From: Stefan Assmann Subject: Introduce config option for pci reroute quirks The config option X86_REROUTE_FOR_BROKEN_BOOT_IRQS is introduced to enable (or disable) the redirection of the interrupt handler to the boot interrupt line by default. Depending on the existence of interrupt masking / threaded interrupt handling in the kernel (vanilla, rt, ...) and the maturity of the rerouting patch, users can enable or disable the redirection by default. This means that the reroute quirk can be applied to any kernel without changing it. Interrupt sharing could be increased if this option is enabled. However this option is vital for threaded interrupt handling, as done by the RT kernel. It should simplify the consolidation with the RT kernel. The option can be overridden by either pci=ioapicreroute or pci=noioapicreroute.

These are even mixed up with hrtimer's lock, resulting in messy lock depencies. Right now, snd-pcsp driver resolves the deadlock by using HRTIMER_CB_SOFTIRQ. However, this isn't nice for a really fast path like bit-flipping. This patch introduces a tasklet for PCM period handling so that the hrtimer callback can be handled fast. This also reduce the use of chip->substream_lock to avoid deadlocks. It's still used in pointer callback, but even this could be removed with a proper barrier. Another good solution is to introduce async trigger callback. But, this will involve with a major rewrite of the PCM core code, so I take first this easy fix.

This should also be a codec-dependent - * flag, maybe the codec should have 3 different - * bits for the three different possibilities how - * it can be hooked up... - * But as long as I don't see any hardware hooked - * up that way... - * - As Apple notes in their code, the tas3004 seems - * to delay the right channel by one sample. You can - * see this when for example recording stereo in - * audacity, or recording the tas output via cable - * on another machine (use a sinus generator or so). - * I tried programming the BiQuads but couldn't - * make the delay work, maybe someone can read the - * datasheet and fix it. The relevant Apple comment - * is in AppleTAS3004Audio.cpp lines 1637 ff. Note - * that their comment describing how they program - * the filters sucks... - * - * Other things: - * - this should actually register *two* aoa_codec - * structs since it has two inputs. Then it must - * use the prepare callback to forbid running the - * secondary output on a different clock. - * Also, whatever bus knows how to do this must - * provide two soundbus_dev devices and the fabric - * must be able to link them correctly. - * - * I don't even know if Apple ever uses the second - * port on the tas3004 though, I don't think their - * i2s controllers can even do it. OTOH, they all - * derive the clocks from common clocks, so it - * might just be possible. The framework allows the - * codec to refine the transfer_info items in the - * usable callback, so we can simply remove the - * rates the second instance is not using when it - * actually is in use. - * Maybe we'll need to make the sound busses have - * a 'clock group id' value so the codec can - * determine if the two outputs can be driven at - * the same time. But that is likely overkill, up - * to the fabric to not link them up incorrectly, - * and up to the hardware designer to not wire - * them up in some weird unusable way. - */ -#include -#include -#include -#include -#include -#include -#include - -MODULE_AUTHOR("Johannes Berg "); -MODULE_LICENSE("GPL"); -MODULE_DESCRIPTION("tas codec driver for snd-aoa"); - -#include "snd-aoa-codec-tas.h" -#include "snd-aoa-codec-tas-gain-table.h" -#include "snd-aoa-codec-tas-basstreble.h" -#include "../aoa.h" -#include "../soundbus/soundbus.h" - -#define PFX "snd-aoa-codec-tas: " - - -struct tas { - struct aoa_codec codec; - struct i2c_client i2c; - u32 mute_l:1, mute_r:1 , - controls_created:1 , - drc_enabled:1, - hw_enabled:1; - u8 cached_volume_l, cached_volume_r; - u8 mixer_l[3], mixer_r[3]; - u8 bass, treble; - u8 acr; - int drc_range; - /* protects hardware access against concurrency from - * userspace when hitting controls and during - * codec init/suspend/resume */ - struct mutex mtx; -}; - -static int tas_reset_init(struct tas *tas); - -static struct tas *codec_to_tas(struct aoa_codec *codec) -{ - return container_of(codec, struct tas, codec); -} - -static inline int tas_write_reg(struct tas *tas, u8 reg, u8 len, u8 *data) -{ - if (len == 1) - return i2c_smbus_write_byte_data(&tas->i2c, reg, *data); - else - return i2c_smbus_write_i2c_block_data(&tas->i2c, reg, len, data); -} - -static void tas3004_set_drc(struct tas *tas) -{ - unsigned char val[6]; - - if (tas->drc_enabled) - val[0] = 0x50; /* 3:1 above threshold */ - else - val[0] = 0x51; /* disabled */ - val[1] = 0x02; /* 1:1 below threshold */ - if (tas->drc_range > 0xef) - val[2] = 0xef; - else if (tas->drc_range < 0) - val[2] = 0x00; - else - val[2] = tas->drc_range; - val[3] = 0xb0; - val[4] = 0x60; - val[5] = 0xa0; - - tas_write_reg(tas, TAS_REG_DRC, 6, val); -} - -static void tas_set_treble(struct tas *tas) -{ - u8 tmp; - - tmp = tas3004_treble(tas->treble); - tas_write_reg(tas, TAS_REG_TREBLE, 1, &tmp); -} - -static void tas_set_bass(struct tas *tas) -{ - u8 tmp; - - tmp = tas3004_bass(tas->bass); - tas_write_reg(tas, TAS_REG_BASS, 1, &tmp); -} - -static void tas_set_volume(struct tas *tas) -{ - u8 block[6]; - int tmp; - u8 left, right; - - left = tas->cached_volume_l; - right = tas->cached_volume_r; - - if (left > 177) left = 177; - if (right > 177) right = 177; - - if (tas->mute_l) left = 0; - if (tas->mute_r) right = 0; - - /* analysing the volume and mixer tables shows - * that they are similar enough when we shift - * the mixer table down by 4 bits.

This patch adds support to the IDT codec families to report jack status to the jack abstraction layer. This required some reorganization in the stac92xx_unsol_event function in which the index value is changed to reporting the nid with the event. Also adds an sigmatel_jack struct to keep track of the nid relation to the jack abstraction layer instance. Also adds functions to set and retrieve data values for each nid, this is used in stac92xx_unsol_event to retrieve the GPIO mask for STAC_VREF_EVENT.

There is a heartbeat bit indicating that the cpu is responding to interrupts, and an idle bit indicating whether the cpu is idle when the heartbeat interrupt occurs. The current period is one second. When a cpu panics, an error code is written by BIOS to this same reg. This patchset provides the following: * x86_64: Add base functionality for writing to the specific SCIR's for each cpu. * heartbeat: Invert "heartbeat" bit to indicate the cpu is "interruptible". If the current thread is the idle thread, then indicate system is "idle". * if hotplug enabled, all bits are set (0xff) when the cpu is disabled.

This can be annoying if you have trace data in the buffers and you experience an oops, but the trace data is old or static. Usually when you want ftrace to dump its contents is when you are debugging your system and you have set up ftrace to trace the events leading to an oops. This patch adds a control variable called "ftrace_dump_on_oops" that will enable the ftrace dump to console on oops. This variable is default off but a developer can enable it either through the kernel command line by adding "ftrace_dump_on_oops" or at run time by setting (or disabling) /proc/sys/kernel/ftrace_dump_on_oops. v2: Replaced /** with /* as Randy explained that kernel-doc does not yet handle variables.

Using code provided by Eric Dumazet, we compute the standard deviation of the average hash bucket chain length while running rt_check_expire. Should any given chain length grow to larger that average plus 4 standard deviations, we trigger an emergency hash table rebuild for that net namespace. This allows for the common case in which chains are well behaved and do not grow unevenly to not incur any latency at all, while those systems (which may be being maliciously attacked), only rebuild when the attack is detected. This patch take 2 other factors into account: 1) chains with multiple entries that differ by attributes that do not affect the hash value are only counted once, so as not to unduly bias system to rebuilding if features like QOS are heavily used 2) if rebuilding crosses a certain threshold (which is adjustable via the added sysctl in this patch), route caching is disabled entirely for that net namespace, since constant rebuilding is less efficient that no caching at all Tested successfully by me.

There were a few things that had conflicts which I have just dropped for now, no harm done. I've built an allyesconfig with this and looked at the files that weren't built very carefully, but it's a huge patch. Signed-off-by: Johannes Berg Signed-off-by: David S.

Biederman" Date: Mon, 27 Oct 2008 17:51:47 -0700 Subject: netns: Coexist with the sysfs limitations v2 To make testing of the network namespace simpler allow the network namespace code and the sysfs code to be compiled and run at the same time. To do this only virtual devices are allowed in the additional network namespaces and those virtual devices are not placed in the kobject tree. Since virtual devices don't actually do anything interesting hardware wise that needs device management there should be no loss in keeping them out of the kobject tree and by implication sysfs. The gain in ease of testing and code coverage should be significant.

This hash table is protected by *one* rwlock. This rwlock is readlocked each time an incoming UDP message is handled. This rwlock is writelocked each time a socket must be inserted in hash table (bind time), or deleted from this table (close time) This is not scalable on SMP machines : 1) Even in read mode, lock() and unlock() are atomic operations and must dirty a contended cache line, shared by all cpus. 2) A writer might be starved if many readers are 'in flight'. This can happen on a machine with some NIC receiving many UDP messages. User process can be delayed a long time at socket creation/dismantle time. This patch prepares RCU migration, by introducing 'struct udp_table and struct udp_hslot', and using one spinlock per chain, to reduce contention on central rwlock. Introducing one spinlock per chain reduces latencies, for port randomization on heavily loaded UDP servers. This also speedup bindings to specific ports. udp_lib_unhash() was uninlined, becoming to big. Some cleanups were done to ease review of following patch (RCUification of UDP Unicast lookups) Signed-off-by: Eric Dumazet Signed-off-by: David S.

Goals are : 1) Optimizing handling of incoming Unicast UDP frames, so that no memory writes should happen in the fast path. Note: Multicasts and broadcasts still will need to take a lock, because doing a full lockless lookup in this case is difficult. 2) No expensive operations in the socket bind/unhash phases : - No expensive synchronize_rcu() calls. - No added rcu_head in socket structure, increasing memory needs, but more important, forcing us to use call_rcu() calls, that have the bad property of making sockets structure cold. (rcu grace period between socket freeing and its potential reuse make this socket being cold in CPU cache). David did a previous patch using call_rcu() and noticed a 20% impact on TCP connection rates. Quoting Cristopher Lameter : "Right. That results in cacheline cooldown. You'd want to recycle the object as they are cache hot on a per cpu basis. That is screwed up by the delayed regular rcu processing. We have seen multiple regressions due to cacheline cooldown. The only choice in cacheline hot sensitive areas is to deal with the complexity that comes with SLAB_DESTROY_BY_RCU or give up on RCU." - Because udp sockets are allocated from dedicated kmem_cache, use of SLAB_DESTROY_BY_RCU can help here. Theory of operation : --------------------- As the lookup is lockfree (using rcu_read_lock()/rcu_read_unlock()), special attention must be taken by readers and writers. Use of SLAB_DESTROY_BY_RCU is tricky too, because a socket can be freed, reused, inserted in a different chain or in worst case in the same chain while readers could do lookups in the same time. In order to avoid loops, a reader must check each socket found in a chain really belongs to the chain the reader was traversing. If it finds a mismatch, lookup must start again at the begining. This *restart* loop is the reason we had to use rdlock for the multicast case, because we dont want to send same message several times to the same socket. We use RCU only for fast path. Thus, /proc/net/udp still takes spinlocks. Signed-off-by: Eric Dumazet Signed-off-by: David S.

"If the socket is moved from one list to another list in-between the time the hash is calculated and the next field is accessed, and the socket has moved to the end of the new list, the traversal will not complete properly on the list it should have, since the socket will be on the end of the new list and there's not a way to tell it's on a new list and restart the list traversal.

On SMP boxes, if code that is being modified is also being executed on another CPU, that CPU will have undefined results. The dynamic ftrace uses kstop_machine to make the system act like a uniprocessor system. But this does not address NMIs, that can still run on other CPUs. One approach to handle this is to make all code that are used by NMIs not be traced. But NMIs can call notifiers that spread throughout the kernel and this will be very hard to maintain, and the chance of missing a function is very high. The approach that this patch takes is to have the NMIs modify the code if the modification is taking place. The way this works is that just writing to code executing on another CPU is not harmful if what is written is the same as what exists. Two buffers are used: an IP buffer and a "code" buffer. The steps that the patcher takes are: 1) Put in the instruction pointer into the IP buffer and the new code into the "code" buffer. 2) Set a flag that says we are modifying code 3) Wait for any running NMIs to finish. 4) Write the code 5) clear the flag. 6) Wait for any running NMIs to finish. If an NMI is executed, it will also write the pending code. Multiple writes are OK, because what is being written is the same. Then the patcher must wait for all running NMIs to finish before going to the next line that must be patched. This is basically the RCU approach to code modification. Thanks to Ingo Molnar for suggesting the idea, and to Arjan van de Ven for his guidence on what is safe and what is not.

Board Compatibility - -This device driver is designed for the Intel i82557 "Speedo3" chip, Intel's -single-chip fast Ethernet controller for PCI, as used on the Intel -EtherExpress Pro 100 adapter. - -II. Board-specific settings - -PCI bus devices are configured by the system at boot time, so no jumpers -need to be set on the board. The system BIOS should be set to assign the -PCI INTA signal to an otherwise unused system IRQ line. While it's -possible to share PCI interrupt lines, it negatively impacts performance and -only recent kernels support it. - -III. Driver operation - -IIIA. General -The Speedo3 is very similar to other Intel network chips, that is to say -"apparently designed on a different planet". This chips retains the complex -Rx and Tx descriptors and multiple buffers pointers as previous chips, but -also has simplified Tx and Rx buffer modes. This driver uses the "flexible" -Tx mode, but in a simplified lower-overhead manner: it associates only a -single buffer descriptor with each frame descriptor. - -Despite the extra space overhead in each receive skbuff, the driver must use -the simplified Rx buffer mode to assure that only a single data buffer is -associated with each RxFD. The driver implements this by reserving space -for the Rx descriptor at the head of each Rx skbuff. - -The Speedo-3 has receive and command unit base addresses that are added to -almost all descriptor pointers. The driver sets these to zero, so that all -pointer fields are absolute addresses. - -The System Control Block (SCB) of some previous Intel chips exists on the -chip in both PCI I/O and memory space. This driver uses the I/O space -registers, but might switch to memory mapped mode to better support non-x86 -processors. - -IIIB. Transmit structure - -The driver must use the complex Tx command+descriptor mode in order to -have a indirect pointer to the skbuff data section. Each Tx command block -(TxCB) is associated with two immediately appended Tx Buffer Descriptor -(TxBD). A fixed ring of these TxCB+TxBD pairs are kept as part of the -speedo_private data structure for each adapter instance. - -The newer i82558 explicitly supports this structure, and can read the two -TxBDs in the same PCI burst as the TxCB. - -This ring structure is used for all normal transmit packets, but the -transmit packet descriptors aren't long enough for most non-Tx commands such -as CmdConfigure. This is complicated by the possibility that the chip has -already loaded the link address in the previous descriptor. So for these -commands we convert the next free descriptor on the ring to a NoOp, and point -that descriptor's link to the complex command. - -An additional complexity of these non-transmit commands are that they may be -added asynchronous to the normal transmit queue, so we disable interrupts -whenever the Tx descriptor ring is manipulated. - -A notable aspect of these special configure commands is that they do -work with the normal Tx ring entry scavenge method. The Tx ring scavenge -is done at interrupt time using the 'dirty_tx' index, and checking for the -command-complete bit. While the setup frames may have the NoOp command on the -Tx ring marked as complete, but not have completed the setup command, this -is not a problem. The tx_ring entry can be still safely reused, as the -tx_skbuff[] entry is always empty for config_cmd and mc_setup frames. - -Commands may have bits set e.g. CmdSuspend in the command word to either -suspend or stop the transmit/command unit. This driver always flags the last -command with CmdSuspend, erases the CmdSuspend in the previous command, and -then issues a CU_RESUME. -Note: Watch out for the potential race condition here: imagine - erasing the previous suspend - the chip processes the previous command - the chip processes the final command, and suspends - doing the CU_RESUME - the chip processes the next-yet-valid post-final-command. -So blindly sending a CU_RESUME is only safe if we do it immediately after -after erasing the previous CmdSuspend, without the possibility of an -intervening delay. Thus the resume command is always within the -interrupts-disabled region. This is a timing dependence, but handling this -condition in a timing-independent way would considerably complicate the code. - -Note: In previous generation Intel chips, restarting the command unit was a -notoriously slow process. This is presumably no longer true. - -IIIC. Receive structure - -Because of the bus-master support on the Speedo3 this driver uses the new -SKBUFF_RX_COPYBREAK scheme, rather than a fixed intermediate receive buffer. -This scheme allocates full-sized skbuffs as receive buffers. The value -SKBUFF_RX_COPYBREAK is used as the copying breakpoint: it is chosen to -trade-off the memory wasted by passing the full-sized skbuff to the queue -layer for all frames vs. the copying cost of copying a frame to a -correctly-sized skbuff. - -For small frames the copying cost is negligible (esp. considering that we -are pre-loading the cache with immediately useful header information), so we -allocate a new, minimally-sized skbuff. For large frames the copying cost -is non-trivial, and the larger copy might flush the cache of useful data, so -we pass up the skbuff the packet was received into. - -IV. Notes - -Thanks to Steve Williams of Intel for arranging the non-disclosure agreement -that stated that I could disclose the information.

This patch adds qdisc_peek_dequeued() wrapper to emulate peek method with qdisc->dequeue() and storing "peeked" skb in qdisc->gso_skb until dequeuing. This is mainly for compatibility reasons not to break some strange configs because peeking is expected for non-work-conserving parent qdiscs to query work-conserving child qdiscs. This implementation requires using qdisc_dequeue_peeked() wrapper instead of directly calling qdisc->dequeue() for all qdiscs ever querried with qdisc->ops->peek() or qdisc_peek_dequeued().

Do this, creating a new unified atmel ASoC architecture to replace the previous at32 and at91 ones.

While an rfkill EPO is active, all transmitters are locked to one of the BLOCKED states and all attempts to change that through the rfkill API (userspace and kernel) will be either ignored or return -EPERM errors. The lock will be released upon receipt of EV_SW SW_RFKILL_ALL ON by rfkill-input, or should modular rfkill-input be unloaded. This makes rfkill and rfkill-input extend the operation of an existing wireless master kill switch to all wireless devices in the system, even those that are not under hardware or firmware control. Since the above is the expected operational behavior for the master rfkill switch, the EPO lock functionality is not optional. Also, extend rfkill-input to allow for three different behaviors when it receives an EV_SW SW_RFKILL_ALL ON input event. The user can set which behavior he wants through the master_switch_mode parameter: master_switch_mode = 0: EV_SW SW_RFKILL_ALL ON just unlocks rfkill controller state changes (so that the rfkill userspace and kernel APIs can now be used to change rfkill controller states again), but doesn't change any of their states (so they will all remain blocked). This is the safest mode of operation, as it requires explicit operator action to re-enable a transmitter. master_switch_mode = 1: EV_SW SW_RFKILL_ALL ON causes rfkill-input to attempt to restore the system to the state before the last EV_SW SW_RFKILL_ALL OFF event, or to the default global states if no EV_SW SW_RFKILL_ALL OFF ever happened. This is the recommended mode of operation for laptops. master_switch_mode = 2: tries to unblock all rfkill controllers (i.e. enable all transmitters) when an EV_SW SW_RFKILL_ALL ON event is received. This is the default mode of operation, as it mimics the previous behavior of rfkill-input. In order to implement these features in a clean way, the entire event handling of rfkill-input was refactored into a single worker function. Protection against input event DoS (repeatedly firing rfkill events for rfkill-input to process) was removed during the code refactoring. It will be added back in a future patch. Note that with these changes, rfkill-input doesn't need to explicitly handle any radio types for which KEY_ or SW_ events do not exist yet. Code to handle EV_SW SW_{WLAN,WWAN,BLUETOOTH,WIMAX,...} was added as it might be needed in the future (and its implementation is not that obvious), but is currently #ifdef'd out to avoid wasting resources.

The old rfkill-input code (before it was refactored) had such a limit in place. It used to drop new events that were past the rate limit. This behaviour was not implemented as an anti-DoS measure, but rather as an attempt to work around deficiencies in input device drivers which would issue multiple KEY_FOO events too soon for a given key FOO (i.e. ones that do not implement mechanical debouncing properly). However, we can't really expect such issues to be worked around by every input handler out there, and also by every userspace client of input devices. It is the input device driver's responsability to do debouncing instead of spamming the input layer with bogus events. The new limiter code is focused only on anti-DoS behaviour, and tries to not lose events (instead, it coalesces them when possible). The transmitters are updated once every 200ms, maximum. Care is taken not to delay a request to _enter_ rfkill transmitter Emergency Power Off (EPO) mode. If mistriggered (e.g. by a jiffies counter wrap), the code delays processing *once* by 200ms.

Once WDS, IBSS or AP/VLAN gets HT capabilities, it will also be wrong, see the comment in ieee80211_enable_ht(). Additionally, this fixes a number of bugs: * mac80211: ieee80211_set_disassoc doesn't notify the driver any more since the refactoring * iwl-agn-rs: always uses the HT capabilities from the wrong stuff mac80211 gives it rather than the actual peer STA * ath9k: a number of bugs resulting from the broken HT API I'm not entirely happy with putting the HT capabilities into struct ieee80211_sta as restricted to our own HT TX capabilities, but I see no cleaner solution for now.

But we cann't kill netdev->priv, because so many drivers reference to it directly. OK, becasue Dave S. Miller said, "every direct netdev->priv usage is a bug", and I want to kill netdev->priv later, I decided to convert all the direct reference of netdev->priv first. In this driver, I don't simply use netdev_priv() to replace netdev->priv. The reason is: Pointer netdev->priv was changed in this driver, but it shouldn't. Because the memory was allocated when alloc_netdev() and netdev->priv should always point to that memory. So I use netdev->ml_priv to replace netdev->priv. After replacing, both ai and ai->wifidev->ml_priv point to the same memory. Signed-off-by: Wang Chen Cc: John W. Linville Cc: Dan Williams Signed-off-by: John W.

Also, since there really is no point in compiling anything without crypto support these days, remove the crypto options and just enable them, leaving only the debugging option which only shows up when a driver is select that requires it. This makes it hard to enable, but most people wouldn't want to anyway. Signed-off-by: Johannes Berg Acked-by: Reinette Chatre Signed-off-by: John W.

Fix this by making mac80211 notify userspace that it didn't associate. [1] my wrt350n in mixed B/G/HT mode often runs into this, maybe it's because one of the antennas is broken off and for whatever reason it decides to use that antenna to transmit the response frames (auth, probe); I do see beacons fine so it's not totally broken.

The consequence is that the STA in ad-hoc mode is inserted/removed quite frequently due to IBSS merging.

I'm convinced that we don't need to do anything to implement multi-domain capability as 802.11-2007 specifies it because it makes only two things mandatory: * starting of BSS/IBSS must have country information (this can easily be done with a mac80211 patch) * a STA must adopt the country information (we already have the framework for this) But we don't have anything implemented anyway for now.

This doesn't exist on legacy-hal but i've tested it on various cards and it works fine. Changes-Licensed-under: ISC Signed-Off-by: Nick Kossifidis Signed-off-by: John W.

This avoids multiple calls to the hypervisor detection function. This patch adds function to detect if we are running under VMware. The current way to check if we are on VMware is following, # check if "hypervisor present bit" is set, if so read the 0x40000000 cpuid leaf and check for "VMwareVMware" signature. # if the above fails, check the DMI vendors name for "VMware" string if we find one we query the VMware hypervisor port to check if we are under VMware. The DMI + "VMware hypervisor port check" is needed for older VMware products, which don't implement the hypervisor signature cpuid leaf. Also note that since we are checking for the DMI signature the hypervisor port should never be accessed on native hardware. This patch also adds a hypervisor_get_tsc_freq function, instead of calibrating the frequency which can be error prone in virtualized environment, we ask the hypervisor for it. We get the frequency from the hypervisor by accessing the hypervisor port if we are running on VMware. Other hypervisors too can add code to the generic routine to get frequency on their platform.

Impact: Changes timebase calibration on Vmware. Use the synthetic TSC_RELIABLE bit to workaround virtualization anomalies. Virtual TSCs can be kept nearly in sync, but because the virtual TSC offset is set by software, it's not perfect. So, the TSC synchronization test can fail. Even then the TSC can be used as a clocksource since the VMware platform exports a reliable TSC to the guest for timekeeping purposes. Use this bit to check if we need to skip the TSC sync checks. Along with this also set the CONSTANT_TSC bit when on VMware, since we still want to use TSC as clocksource on VM running over hardware which has unsynchronized TSC's (opteron's), since the hypervisor will take care of providing consistent TSC to the guest.

Impact: Changes timekeeping on Vmware (or with tsc=reliable). This is achieved by resetting the CLOCKSOURCE_MUST_VERIFY flag. We add a tsc=reliable commandline option to enable this. This enables legacy hardware without HPET, LAPIC, or ACPI timers to enter high-resolution timer mode. Along with that have extended this to be used in virtualization environement too. Now we also set this flag if the X86_FEATURE_TSC_RELIABLE bit is set. This is important since there is a wrap-around problem with the acpi_pm timer. The acpi_pm counter is just 24bits and this can overflow in ~4 seconds. With the NO_HZ kernels in virtualized environment, there can be situations when the guest is descheduled for longer duration, as a result we may miss the wrap of the acpi counter. When TSC is used as a clocksource and acpi_pm timer is being used as the watchdog clocksource this error in acpi_pm results in TSC being marked as unstable, and essentially results in time dropping in chunks of 4 seconds whenever this wrap is missed. Since the virtualized TSC is reliable on VMware, we should always use the TSCs clocksource on VMware, so we skip the verfication at runtime, by checking for the feature bit. Since we reset the flag for mgeode systems too, i have combined the mgeode case with the feature bit check.

So I would suggest so either hard-wire the tfifo qdisc or at least make the assumption that inner qdiscs are work-conserving.", and later: "- a lot of other qdiscs still don't work as inner qdiscs of netem [...]". So, according to his suggestion, this patch removes classful options of netem. The main reason of this change is to remove ops->requeue() method, which is currently used only by netem.

Grepping the kernel I see that forcedeth has the second lowest value of all ethernet drivers (ie, 6). Most are in the 20-40 range. So this patch increases this a bit, from 6 to 15 (at 15 forcedeth becomes the driver with third-lowest max_interrupt_work value). My test stand, which used to print out the above warnings repetitively whenever it was under heavy net load, no longer does so.

Impact: add new tracepoint APIs to allow the batched registration of probes new APIs separate tracepoint_probe_register(), tracepoint_probe_unregister() into 2 steps. The first step of them is just update tracepoint_entry, not connect or disconnect. this patch introduces tracepoint_probe_update_all() for update all. these APIs are very useful for registering lots of probes but just updating once. Another very important thing is that *_noupdate APIs do not require module_mutex.

When WOL is enabled and management firmware is disabled, incoming packets are evaluated and discarded at the chip's rule processor. When management firmware is enabled, the hardware must be informed that there are agents further up the stack that still use the incoming frames. Normally management firmware will configure the MAC correctly on its own, but there can be cases where the setting could get clobbered by the driver. The first hunk of this patch preserves this setting. The second hunk of this patch wipes out the driver present signature of the APE memory space. By doing so, the DASH firmware can assume driver absent behavior. Signed-off-by: Matt Carlson Signed-off-by: Michael Chan Signed-off-by: David S.

The patch was understandably conservative, so this patch elaborates on that work. The patch starts by creating a single point in tg3_set_power_state() to decide whether or not to enable WOL. The rest of the code in tg3_set_power_state() was then pivoted to use the result of this decision. The patch then makes sure the device is allowed to wakeup before reporting whether or not WOL is currently enabled. The final hunks of the patch consolidate where the WOL capability and WOL enabled flags are set to a single location. Signed-off-by: Matt Carlson Signed-off-by: Michael Chan Signed-off-by: David S.

The patch does the following things : * Rename tg3_mdio_config() to tg3_mdio_config_5785(). The 5785 will be the only device that will use it so the name might as well reflect that. * Fix a memory leak if mdiobus_register() fails. * Add code to deal with phy device detection failures. * Add code to correct the supported list of phy features based on the MAC <=> PHY interface.

If the NEED_RESCHED flag is set, a preempt_enable will call schedule. Inside the schedule function, the NEED_RESCHED flag is cleared. The problem arises when a trace happens in the schedule function but before NEED_RESCHED is cleared. The race is as follows: schedule() >> tracer called trace_function() preempt_disable() [ record trace ] preempt_enable() <<- here's the issue. [check NEED_RESCHED] schedule() [ Repeat the above, over and over again ] The naive approach is simply to use preempt_enable_no_schedule instead. The problem with that approach is that, although we solve the schedule recursion issue, we now might lose a preemption check when not in the schedule function. trace_function() preempt_disable() [ record trace ] [Interrupt comes in and sets NEED_RESCHED] preempt_enable_no_resched() [continue without scheduling] The way ftrace handles this problem is with the following approach: int resched; resched = need_resched(); preempt_disable_notrace(); [record trace] if (resched) preempt_enable_no_sched_notrace(); else preempt_enable_notrace(); This may seem like the opposite of what we want. If resched is set then we call the "no_sched" version?? The reason we do this is because if NEED_RESCHED is set before we disable preemption, there's two reasons for that: 1) we are in an atomic code path 2) we are already on our way to the schedule function, and maybe even in the schedule function, but have yet to clear the flag. Both the above cases we do not want to schedule. This solution has already been implemented within the ftrace infrastructure. But the problem is that it has been implemented several times. This patch encapsulates this code to two nice functions. resched = ftrace_preempt_disable(); [ record trace] ftrace_preempt_enable(resched); This way the tracers do not need to worry about getting it right.

If an interrupt occurred, it would not be traced, because the function tracer protects itself from recursion. This may be faster, but the trace output might miss some traces. This patch makes the fuction trace disable interrupts, but it also adds a runtime feature to disable preemption instead. It does this by having two different tracer functions. When the function tracer is enabled, it will check to see which version is requested (irqs disabled or preemption disabled). Then it will use the corresponding function as the tracer. Irq disabling is the default behaviour, but if the user wants better performance, with the chance of missing traces, then they can choose the preempt disabled version. Running hackbench 3 times with the irqs disabled and 3 times with the preempt disabled function tracer yielded: tracing type times entries recorded ------------ -------- ---------------- irq disabled 43.393 166433066 43.282 166172618 43.298 166256704 preempt disabled 38.969 159871710 38.943 159972935 39.325 161056510 Average: irqs disabled: 43.324 166287462 preempt disabled: 39.079 160300385 preempt is 10.8 percent faster than irqs disabled. I wrote a patch to count function trace recursion and reran hackbench. With irq disabled: 1,150 times the function tracer did not trace due to recursion. with preempt disabled: 5,117,718 times. The thousand times with irq disabled could be due to NMIs, or simply a case where it called a function that was not protected by notrace. But we also see that a large amount of the trace is lost with the preempt version.

It doesn't make sense to check the DNAT target against the local route source.

The following feature-negotiation data structures are provided: * a container for the various (SP or NN) values, * symbolic state names to track feature states, * an entry struct which holds all current information together, * elementary functions to fill in and process these structures. Entry structs are arranged as FIFO for the following reason: RFC 4340 specifies that if multiple options of the same type are present, they are processed in the order of their appearance in the packet; which means that this order needs to be preserved in the local data structure (the later insertion code also respects this order). The struct list_head has been chosen for the following reasons: the most frequent operations are * add new entry at tail (when receiving Change or setting socket options); * delete entry (when Confirm has been received); * deep copy of entire list (cloning from listening socket onto request socket). The NN value has been set to 64 bit, which is a currently sufficient upper limit (Sequence Window feature has 48 bit). Thanks to Arnaldo, who contributed the streamlined layout of the entry struct.

While tcp_memory_allocated is seldom used, it appears each incoming UDP frame is currently touching udp_memory_allocated when queued, and when received by application. One possible solution is to use sk_mem_reclaim_partial() instead of sk_mem_reclaim(), so that we keep a small reserve (less than one page) of memory for each UDP socket. We did something very similar on TCP side in commit 9993e7d313e80bdc005d09c7def91903e0068f07 ([TCP]: Do not purge sk_forward_alloc entirely in tcp_delack_timer()) A more complex solution would need to convert prot->memory_allocated to use a percpu_counter with batches of 64 or 128 pages.

This moves the code that looks for the ibm,interrupt-server#-size properties from xics_update_irq_servers() into xics_init_IRQ(). Also this adds a check for mismatched sizes across the interrupt source controller nodes. Not sure this is necessary as in this case the firmware might be seriously busted. This property only appears on POWER6 boxes and is only used in the set-indicator(gqirm) call, and apparently firmware currently ignores the value we pass. Nevertheless we need to fix it in case future firmware versions use it.

These new feature sections will only affect Power6 and Cell because the CPU feature bit was only added to these two processors. Power6 gets its best performance in memcpy() when aligning neither the source nor the destination, while Cell gets its best performance when just the destination is aligned. But in order to save on CPU feature bits we can use the previously added CPU_FTR_CP_USE_DCBTZ feature bit to differentiate between Power6 and Cell (because CPU_FTR_CP_USE_DCBTZ was added to Cell but not Power6). The first feature section acts to nop out the branch that takes us to the code that aligns us to an eight byte boundary for the destination. We only want to nop out this branch on Power6. So the ALT_FTR_SECTION_END() for this feature section creates a test mask of the two feature bits ORed together and provides an expected result of just CPU_FTR_UNALIGNED_LD_STD, thus we nop out the branch if we're on a CPU that has CPU_FTR_UNALIGNED_LD_STD set and CPU_FTR_CP_USE_DCBTZ unset. For the second feature section added, if we're on a CPU that has the CPU_FTR_UNALIGNED_LD_STD bit set then we don't want to do the copy with aligned loads and stores (and the appropriate shifting left and right instructions), so we want to nop out the branch to .Lsrc_unaligned. The andi. used for this branch is moved to just above the branch because this allows us to nop out both instructions with just one feature section which gives us better performance and doesn't hurt readability which two separate feature sections did. Moving the andi. to just above the branch doesn't have any noticeable negative effect on the remaining 64bit processors (the ones that didn't have this feature bit added). On Cell this simple modification results in an improvement to measured memcpy() bandwidth of up to 50% in the hot cache case and up to 15% in the cold cache case. On Power6 we get memory bandwidth results that are up to three times faster in the hot cache case and up to 50% faster in the cold cache case. Commit 2a9294369bd020db89bfdf78b84c3615b39a5c84 ("powerpc: Add new CPU feature: CPU_FTR_CP_USE_DCBTZ") was where CPU_FTR_CP_USE_DCBTZ was added. To say that Cell gets its best performance in memcpy() with just the destination aligned is true but only for the reason that the indirect shift and rotate instructions, sld and srd, are microcoded on Cell. This means that either the destination or the source can be aligned, but not both, and seeing as we get better performance with the destination aligned we choose this option. While we're at it make a one line change from cmpldi r1,... to cmpldi cr1,... for consistency.

This unifies this in large part, by making 32-bit use a routine very similar to what 64-bit does when initially scanning the PCI busses. The actual setup of the PHB resources itself is then moved to a common function in pci-common.c. This should cause no functional change on 64-bit. On 32-bit, the effect is that the PHB resources are going to be setup a bit earlier, instead of being setup from pcibios_fixup_bus().

One is to set up things related to the bus itself, such as reading bridge resources for P2P bridges, fixing them up, or setting up the iommu's associated with bridges on some platforms. The other is some setup for each individual device under that bridge, mostly setting up DMA mappings and interrupts. The problem is that this approach doesn't work well with PCI hotplug when an existing bus is re-probed for new children. We fix this problem by splitting pcibios_fixup_bus into two routines: pcibios_setup_bus_self() is now called to setup the bus itself pcibios_setup_bus_devices() is now called to setup devices pcibios_fixup_bus() is then modified to call these two after reading the bridge bases, and the OF based PCI probe is modified to avoid calling into the first one when rescanning an existing bridge.

The nanoseconds field of the result is obtained by computing a microseconds value and multiplying by 1000. This changes the code in the VDSO to do the computation for clock_gettime with nanosecond resolution. That means that the resolution of the result will ultimately depend on the timebase frequency. Because the timestamp in the VDSO datapage (stamp_xsec, the real time corresponding to the timebase count in tb_orig_stamp) is in units of 2^-20 seconds, it doesn't have sufficient resolution for computing a result with nanosecond resolution. Therefore this adds a copy of xtime to the VDSO datapage and updates it in update_gtod() along with the other time-related fields.

Hallyn" Date: Wed, 5 Nov 2008 16:08:52 -0600 Subject: file capabilities: add no_file_caps switch (v4) Add a no_file_caps boot option when file capabilities are compiled into the kernel (CONFIG_SECURITY_FILE_CAPABILITIES=y). This allows distributions to ship a kernel with file capabilities compiled in, without forcing users to use (and understand and trust) them. When no_file_caps is specified at boot, then when a process executes a file, any file capabilities stored with that file will not be used in the calculation of the process' new capability sets. This means that booting with the no_file_caps boot option will not be the same as booting a kernel with file capabilities compiled out - in particular a task with CAP_SETPCAP will not have any chance of passing capabilities to another task (which isn't "really" possible anyway, and which may soon by killed altogether by David Howells in any case), and it will instead be able to put new capabilities in its pI. However since fI will always be empty and pI is masked with fI, it gains the task nothing. We also support the extra prctl options, setting securebits and dropping capabilities from the per-process bounding set. The other remaining difference is that killpriv, task_setscheduler, setioprio, and setnice will continue to be hooked. That will be noticable in the case where a root task changed its uid while keeping some caps, and another task owned by the new uid tries to change settings for the more privileged task.

For virtual devices left in a network namespace that is exiting we have no need to preserve them and we now have the infrastructure that allows us to delete them. So delete virtual devices when we exit a network namespace. Keeping the necessary user space clean up after a network namespace exits much more tractable.

In looking at the code it became apparrent that we have and will continue to have cases where if we have anything going on in a network namespace there will be assumptions that the loopback device is present. Things like sending igmp unsubscribe messages when we bring down network devices invokes the routing code which assumes that at least the loopback driver is present. Therefore to avoid magic initcall ordering hackery that is hard to follow and hard to get right insert a call to register the loopback device directly from net_dev_init(). This guarantes that the loopback device is the first device registered and the last network device to go away. Signed-off-by: Eric W. Biederman Signed-off-by: David S.

Usage count = 3 unregister_netdevice: waiting for lo to become free. Usage count = 3 unregister_netdevice: waiting for lo to become free. Usage count = 3 It turns out that if you listen on a multicast address an unsubscribe packet is sent when the network device goes down. If you shutdown the network namespace without carefully cleaning up this can trigger the unsubscribe packet to be sent over the loopback interface while the network namespace is going down. All of which is fine except when we drop the packet and forget to free it leaking the skb and the dst entry attached to. As it turns out the dst entry hold a reference to the idev which holds the dev and keeps everything from being cleaned up. Yuck!

Both regular bonds and VLANs over bonds are supported. - Adds a new tunable, num_unsol_na, to limit the number of unsolicited IPv6 Neighbor Advertisements that are sent on a failover event. Default is 1. - Creates two new IPv6 neighbor discovery functions: ndisc_build_skb() ndisc_send_skb() These were required to support VLANs since we have to be able to add the VLAN id to the skb since ndisc_send_na() and friends shouldn't be asked to do this. These two routines are basically __ndisc_send() split into two pieces, in a slightly different order. - Updates Documentation/networking/bonding.txt and bumps the rev of bond support to 3.4.0. On failover, this new code will generate one packet: - An unsolicited IPv6 Neighbor Advertisement, which helps the switch learn that the address has moved to the new slave. Testing has shown that sending just the NA results in pretty good behavior when in active-back mode, I saw no lost ping packets for example.

This causes traffic on those VLANs to all be assigned the same slave. This patch corrects that misbehavior by locating the bonding interface nested below the VLAN interface. Bug reported by Sven Anders , who also tested an earlier version of this patch and confirmed that it resolved the problem.

The existing policy, now termed "stable," selects the active aggregator by greatest bandwidth, and only reselects a new aggregator if the active aggregator is entirely disabled (no more ports or all ports down). This patch adds two new policies: bandwidth and count, selecting the active aggregator by total bandwidth (like the stable policy) or by the number of ports in the aggregator, respectively. These two policies also differ from the stable policy in that they will reselect the active aggregator when availability-related changes occur in the bond (e.g., link state change). This permits "gang failover" within 802.3ad, allowing redundant aggregators along parallel paths to always maintain the "best" aggregator as the active aggregator (rather than having to wait for the active to entirely fail). This patch also updates the driver version to 3.5.0.

It adds a new variable called function_trace_stop which will stop the calls to functions from mcount when set. This is just an on/off switch and does not handle recursion like preempt_disable(). It's main purpose is to help other tracers/debuggers start and stop tracing fuctions without the need to call kstop_machine. The config option HAVE_FUNCTION_TRACE_MCOUNT_TEST is added for archs that implement the testing of the function_trace_stop in the mcount arch dependent code. Otherwise, the test is done in the C code. x86 is the only arch at the moment that supports this.

If tracing_enabled is changed to zero (by echo'ing 0 into the tracing_enabled file) a full shutdown is performed. The full startup and shutdown of a tracer can be expensive and the user can lose out traces when echo'ing in 0 to the tracing_enabled file, because the process takes too long. There can also be places that the user would like to start and stop the tracer several times and doing the full startup and shutdown of a tracer might be too expensive. This patch performs the full startup and shutdown when a tracer is selected. It also adds a way to do a quick start or stop of a tracer. The quick version is just a flag that prevents the tracing from taking place, but the overhead of the code is still there. For example, the startup of a tracer may enable tracepoints, or enable the function tracer. The stop and start will just set a flag to have the tracer ignore the calls when the tracepoint or function trace is called. The overhead of the tracer may still be present when the tracer is stopped, but no tracing will occur. Setting the tracer to the 'nop' tracer (or any other tracer) will perform the shutdown of the tracer which will disable the tracepoint or disable the function tracer. The tracing_enabled file will simply start or stop tracing. This change is all internal. The end result for the user should be the same as before. If tracing_enabled is not set, no trace will happen. If tracing_enabled is set, then the trace will happen. The tracing_enabled variable is static between tracers. Enabling tracing_enabled and going to another tracer will keep tracing_enabled enabled. Same is true with disabling tracing_enabled. This patch will now provide a fast start/stop method to the users for enabling or disabling tracing. Note: There were two methods to the struct tracer that were never used: The methods start and stop. These were to be used as a hook to the reading of the trace output, but ended up not being necessary. These two methods are now used to enable the start and stop of each tracer, in case the tracer needs to do more than just not write into the buffer. For example, the irqsoff tracer must stop recording max latencies when tracing is stopped.

What happens is that the tracer will start tracing the lockdep code while lockdep is testing the ring buffers locks. This can cause lockdep to fail due to testing cases that have not fully finished their locking transition. This patch converts the spin locks used by the ring buffer back into raw spin locks which lockdep does not check.

This patch adds a preparation phase just to probe codec addresses before actually creating codec instances. If any error occurs during this probing phase, the driver resets the controller to recover. This will (hopefully) fix the famous "single_cmd" errors.

It is named lifebook as fujitsu is in use for Amilo machines. This builds on the Quanta FL1 work and supports all analog inputs & outputs that I am aware of. Microphone autoswitch is implemented. The laptop mic port takes precedence over the dock mic port if both happen to have a jack plugged in. This made sense to me as a design decision (imagine a presentation environment with the dock fully wired in and the presenter quickly wanting to override the mic with a headset). There is mention of a digital audio path on the codec graph, so perhaps the headphone socket is dual-function analog/digital.

We started seeing deterioration in it's performance recently. The test should never take more than 10 microseconds, but we started 5-10% failure rate. Using elimination method, we traced the problem to commit 1b12bbc747560ea68bcc132c3d05699e52271da0 (lockdep: re-annotate scheduler runqueues). When LOCKDEP is disabled, this patch only adds an additional function call to double_unlock_balance(). Hence I inlined double_unlock_balance() and the problem went away. Here is a patch to make this change.

Biederman" Date: Fri, 7 Nov 2008 22:54:20 -0800 Subject: net: Guaranetee the proper ordering of the loopback device. v2 I was recently hunting a bug that occurred in network namespace cleanup. In looking at the code it became apparrent that we have and will continue to have cases where if we have anything going on in a network namespace there will be assumptions that the loopback device is present. Things like sending igmp unsubscribe messages when we bring down network devices invokes the routing code which assumes that at least the loopback driver is present. Therefore to avoid magic initcall ordering hackery that is hard to follow and hard to get right insert a call to register the loopback device directly from net_dev_init(). This guarantes that the loopback device is the first device registered and the last network device to go away. But do it carefully so we register the loopback device after we clear dev_boot_phase.

The principle of the classifier is to directly access the task_struct via get_current(). In order for this to work, classification requests from softirqs must be ignored. This is not a problem because the vast majority of packets in softirq context are not assigned to a task anyway. For this to work, a mechanism is needed to trace softirq context. This repost goes back to the method of relying on the number of nested bh disable calls for the sake of not adding too much complexity and the option to come up with something more reliable if actually needed.

If one CPU is very active at the end of the trace, its history will not go as far back as the other CPU traces. This means that output for a particular CPU may not appear for the first part of a trace. To help annotate what is happening, and to prevent any more confusion, this patch adds a line that annotates the start of a CPU buffer output. For example: automount-3495 [001] 184.596443: dnotify_parent <-vfs_write [...] automount-3495 [001] 184.596449: dput <-path_put automount-3496 [002] 184.596450: down_read_trylock <-do_page_fault [...] sshd-3497 [001] 184.597069: up_read <-do_page_fault -0 [000] 184.597074: __exit_idle <-exit_idle [...] automount-3496 [002] 184.597257: filemap_fault <-__do_fault -0 [003] 184.597261: exit_idle <-smp_apic_timer_interrupt Note, parsers of a trace output should always ignore any lines that start with a '#'.

Also set TSF to 0 to start TSF increment on AP mode. We need to handle sleep timers for AR5212 there + add support for PCF. * Properly clean MIC key from keytable when TKIP is used (Bob is working on set_key function etc so i leave it for now). Tested on AR5212 (Hainan) and AR5413 and works fine v2 Set PISR on AR5211+ and ISR on AR5210, got to sleep more ;-) Changes-Licensed-under: ISC Signed-Off-by: Nick Kossifidis Signed-off-by: John W.

For example, a managed interface (wlan0) and a monitor interface (mon0) can exist at the same time. Thus priv->iw_mode is not sufficient to track the wireless mode any more. The patch redefines priv->iw_mode as the first interface mode (the same as priv->vif->type if priv->vif != NULL). If another monitor type interface is created later, we don't change priv->iw_mode into monitor. This way, the original interface still works. The patch also requests mac80211 to do reassociation after we change the Rx filter flags. Signed-off-by: Zhu Yi Signed-off-by: Reinette Chatre Signed-off-by: John W.

Consequently, it is time to allow this mode to be enabled without having to patch the kernel. AP mode requires hostapd for management frame processing and as such, configuring this mode is only allowed through cfg80211 (not with iwconfig and WEXT).

Following values can be written into this file to change PS mode: 0 = power save disabled (constantly awake) 1 = power save enabled (drop all frames; do not send PS-Poll) 2 = power save enabled (send PS-Poll frames automatically to receive buffered unicast frames); not yet fully implemented 3 = manual PS-Poll trigger (send a single PS-Poll frame) Two different behavior for power save mode processing can be tested: - move between modes 1 and 0 (i.e., receive all buffered frames at a time) - move to mode 1 and use manual PS-Poll frames (write 3 to the 'ps' debugfs file) to fetch power save buffered frames one at a time Mode 2 (automatic PS-Poll) does not yet parse Beacon frames, but eventually, it should take a look at TIM IE and send PS-Poll if a traffic bit is set for our AID.

This adds intersection support. When we enable 802.11d support we will use this to intersect the regulatory domain from the AP's country IE and what our regulatory agent believes is correct for a country. This patch enables intersection for now in the case where the last regdomain was set by a country IE which was parsed and the user then wants to set the regulatory domain. Since we don't support country IE parsing yet this code path will not be hit, however this allows us to pave the way for 11d support. Intersection code has been tested in userspace with CRDA.

The lock protects both the + * hardware and the struct orinoco_private. + * + * Another flag, priv->hw_unavailable indicates that the hardware is + * unavailable for an extended period of time (e.g. suspended, or in + * the middle of a hard reset). This flag is protected by the + * spinlock. All code which touches the hardware should check the + * flag after taking the lock, and if it is set, give up on whatever + * they are doing and drop the lock again. The orinoco_lock() + * function handles this (it unlocks and returns -EBUSY if + * hw_unavailable is non-zero). + */ + +#define DRIVER_NAME "orinoco" + +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include + +#include +#include + +#include "hermes_rid.h" +#include "hermes_dld.h" +#include "orinoco.h" + +/********************************************************************/ +/* Module information */ +/********************************************************************/ + +MODULE_AUTHOR("Pavel Roskin & David Gibson "); +MODULE_DESCRIPTION("Driver for Lucent Orinoco, Prism II based and similar wireless cards"); +MODULE_LICENSE("Dual MPL/GPL"); + +/* Level of debugging.

If you do not delete the + * provisions above, a recipient may use your version of this file + * under either the MPL or the GPL. + * + * Here's the general details on how the PLX9052 adapter works: + * + * - Two PCI I/O address spaces, one 0x80 long which contains the + * PLX9052 registers, and one that's 0x40 long mapped to the PCMCIA + * slot I/O address space. + * + * - One PCI memory address space, mapped to the PCMCIA attribute space + * (containing the CIS). + * + * Using the later, you can read through the CIS data to make sure the + * card is compatible with the driver. Keep in mind that the PCMCIA + * spec specifies the CIS as the lower 8 bits of each word read from + * the CIS, so to read the bytes of the CIS, read every other byte + * (0,2,4,...). Passing that test, you need to enable the I/O address + * space on the PCMCIA card via the PCMCIA COR register. This is the + * first byte following the CIS. In my case (which may not have any + * relation to what's on the PRISM2 cards), COR was at offset 0x800 + * within the PCI memory space. Write 0x41 to the COR register to + * enable I/O mode and to select level triggered interrupts. To + * confirm you actually succeeded, read the COR register back and make + * sure it actually got set to 0x41, in case you have an unexpected + * card inserted. + * + * Following that, you can treat the second PCI I/O address space (the + * one that's not 0x80 in length) as the PCMCIA I/O space. + * + * Note that in the Eumitcom's source for their drivers, they register + * the interrupt as edge triggered when registering it with the + * Windows kernel. I don't recall how to register edge triggered on + * Linux (if it can be done at all). But in some experimentation, I + * don't see much operational difference between using either + * interrupt mode. Don't mess with the interrupt mode in the COR + * register though, as the PLX9052 wants level triggers with the way + * the serial EEPROM configures it on the WL11000. + * + * There's some other little quirks related to timing that I bumped + * into, but I don't recall right now. Also, there's two variants of + * the WL11000 I've seen, revision A1 and T2. These seem to differ + * slightly in the timings configured in the wait-state generator in + * the PLX9052. There have also been some comments from Eumitcom that + * cards shouldn't be hot swapped, apparently due to risk of cooking + * the PLX9052. I'm unsure why they believe this, as I can't see + * anything in the design that would really cause a problem, except + * for crashing drivers not written to expect it. And having developed + * drivers for the WL11000, I'd say it's quite tricky to write code + * that will successfully deal with a hot unplug. Very odd things + * happen on the I/O side of things. But anyway, be warned. Despite + * that, I've hot-swapped a number of times during debugging and + * driver development for various reasons (stuck WAIT# line after the + * radio card's firmware locks up). + */ + +#define DRIVER_NAME "orinoco_plx" +#define PFX DRIVER_NAME ": " + +#include +#include +#include +#include +#include +#include + +#include "orinoco.h" +#include "orinoco_pci.h" + +#define COR_OFFSET (0x3e0) /* COR attribute offset of Prism2 PC card */ +#define COR_VALUE (COR_LEVEL_REQ | COR_FUNC_ENA) /* Enable PC card with interrupt in level trigger */ +#define COR_RESET (0x80) /* reset bit in the COR register */ +#define PLX_RESET_TIME (500) /* milliseconds */ + +#define PLX_INTCSR 0x4c /* Interrupt Control & Status Register */ +#define PLX_INTCSR_INTEN (1<<6) /* Interrupt Enable bit */ + +/* + * Do a soft reset of the card using the Configuration Option Register + */ +static int orinoco_plx_cor_reset(struct orinoco_private *priv) +{ + hermes_t *hw = &priv->hw; + struct orinoco_pci_card *card = priv->card; + unsigned long timeout; + u16 reg; + + iowrite8(COR_VALUE | COR_RESET, card->attr_io + COR_OFFSET); + mdelay(1); + + iowrite8(COR_VALUE, card->attr_io + COR_OFFSET); + mdelay(1); + + /* Just in case, wait more until the card is no longer busy */ + timeout = jiffies + (PLX_RESET_TIME * HZ / 1000); + reg = hermes_read_regn(hw, CMD); + while (time_before(jiffies, timeout) && (reg & HERMES_CMD_BUSY)) { + mdelay(1); + reg = hermes_read_regn(hw, CMD); + } + + /* Still busy? */ + if (reg & HERMES_CMD_BUSY) { + printk(KERN_ERR PFX "Busy timeout\n"); + return -ETIMEDOUT; + } + + return 0; +} + +static int orinoco_plx_hw_init(struct orinoco_pci_card *card) +{ + int i; + u32 csr_reg; + static const u8 cis_magic[] = { + 0x01, 0x03, 0x00, 0x00, 0xff, 0x17, 0x04, 0x67 + }; + + printk(KERN_DEBUG PFX "CIS: "); + for (i = 0; i < 16; i++) { + printk("%02X:", ioread8(card->attr_io + (i << 1))); + } + printk("\n"); + + /* Verify whether a supported PC card is present */ + /* FIXME: we probably need to be smarted about this */ + for (i = 0; i < sizeof(cis_magic); i++) { + if (cis_magic[i] != ioread8(card->attr_io + (i << 1))) { + printk(KERN_ERR PFX "The CIS value of Prism2 PC " + "card is unexpected\n"); + return -ENODEV; + } + } + + /* bjoern: We need to tell the card to enable interrupts, in + case the serial eprom didn't do this already.

Keep in mind that the PCMCIA - * spec specifies the CIS as the lower 8 bits of each word read from - * the CIS, so to read the bytes of the CIS, read every other byte - * (0,2,4,...). Passing that test, you need to enable the I/O address - * space on the PCMCIA card via the PCMCIA COR register. This is the - * first byte following the CIS. In my case (which may not have any - * relation to what's on the PRISM2 cards), COR was at offset 0x800 - * within the PCI memory space. Write 0x41 to the COR register to - * enable I/O mode and to select level triggered interrupts. To - * confirm you actually succeeded, read the COR register back and make - * sure it actually got set to 0x41, in case you have an unexpected - * card inserted. - * - * Following that, you can treat the second PCI I/O address space (the - * one that's not 0x80 in length) as the PCMCIA I/O space. - * - * Note that in the Eumitcom's source for their drivers, they register - * the interrupt as edge triggered when registering it with the - * Windows kernel. I don't recall how to register edge triggered on - * Linux (if it can be done at all). But in some experimentation, I - * don't see much operational difference between using either - * interrupt mode. Don't mess with the interrupt mode in the COR - * register though, as the PLX9052 wants level triggers with the way - * the serial EEPROM configures it on the WL11000. - * - * There's some other little quirks related to timing that I bumped - * into, but I don't recall right now. Also, there's two variants of - * the WL11000 I've seen, revision A1 and T2. These seem to differ - * slightly in the timings configured in the wait-state generator in - * the PLX9052. There have also been some comments from Eumitcom that - * cards shouldn't be hot swapped, apparently due to risk of cooking - * the PLX9052. I'm unsure why they believe this, as I can't see - * anything in the design that would really cause a problem, except - * for crashing drivers not written to expect it. And having developed - * drivers for the WL11000, I'd say it's quite tricky to write code - * that will successfully deal with a hot unplug. Very odd things - * happen on the I/O side of things. But anyway, be warned.

This plug-in stores return addresses on the thread_info structure of the current task. The index of the current return address is initialized when the task is the first one (init) and when a process forks (the child). It is not needed when a task does a sys_execve because after this syscall, it still needs to return on the kernel functions it called. Note that the code of return_to_handler has been suggested by Steven Rostedt as almost all of the ideas of improvements in this V3. For purpose of security, arch/x86/kernel/process_32.c is not traced because __switch_to() changes the current task during its execution. That could cause inconsistency in the stored return address of this function even if I didn't have any crash after testing with tracing on this function enabled.

For example, the current method to obtain exec time of a group entity is not always accurate. One has to read the exec times of all the tasks(/proc//sched) in the group and add them. This method fails (or becomes difficult) if we want to collect stats of a group over a duration where tasks get created and terminated. This patch makes it easier to obtain group stats by directly including them in /proc/sched_debug. Stats like group exec time would help user programs (like LTP) to accurately measure the group fairness.

Its possible (and actually often happens) that the capability system accidentally stumbled into a valid memory region but it also regularly happens that it hits invalid memory and BUGs. If such an operation does get past cap_capable then the selinux system is sure to have problems as it already does a (simple) validity check and BUG. This is known to happen by the broken and buggy firegl driver. This patch cleanly checks all capable calls and BUG if a call is for an invalid capability. This will likely break the firegl driver for some situations, but it is the right thing to do.

Currently this is the case at least for filesystems when deciding if a process can use the reserved 'root' blocks and for the case of things like the oom algorithm determining if processes are root processes and should be less likely to be killed. These types of security system requests should not be audited or logged since they are not really security decisions. It would be possible to solve this problem like the vm_enough_memory security check did by creating a new LSM interface and moving all of the policy into that interface but proves the needlessly bloat the LSM and provide complex indirection. This merely allows those decisions to be made where they belong and to not flood logs or printk with denials for thing that are not security decisions.

When command 'halt -f' is invoked, the message "System halted." is displayed but this is not really true because all CPUs are still running. There are also similar inconsistencies for other arches (some uses power-off for halt or forever-loop with IRQs enabled/disabled).

If port CF9 seems to be safe to touch, attempt it before trying the keyboard controller. Port CF9 is not available on all chipsets (a significant but decreasing number of modern chipsets don't implement it), but port CF9 itself should in general be safe to poke (no ill effects if unimplemented) on any system which has PCI Configuration Method #1 or #2, as it falls inside the PCI configuration port range in both cases. No chipset without PCI is known to have port CF9, either, although an explicit "pci=bios" would mean we miss this and therefore don't use port CF9. An explicit "reboot=pci" can be used to force the use of port CF9. Signed-off-by: H.

Although it is theoretically possible to perform feature negotiation at any time (and RFC 4340 supports this), in practice this is prohibitively complex, as it requires to put traffic on hold for each new negotiation. 2. As a byproduct of restricting feature negotiation to connection setup, the feature-negotiation retransmit timer is no longer required. This part is now mapped onto the protocol-level retransmission. Details indicating why timers are no longer needed can be found on http://www.erg.abdn.ac.uk/users/gerrit/dccp/notes/feature_negotiation/\ implementation_notes.html This patch disables anytime negotiation, subsequent patches work out full feature negotiation support for connection setup.

The data structure is a table which is filled in at compile-time with the list of available CCIDs (which in turn depends on the Kconfig choices). Using the copy function for cloning the list of supported CCIDs is useful for feature negotiation, since the negotiation is now with the full list of available CCIDs (e.g. {2, 3}) instead of the default value {2}.

Most notably, this is the Send Ack Vector feature, but also Ack Ratio and Send Loss Event Rate (also taken care of). For Send Ack Vector, the situation is as follows: * since CCID2 mandates the use of Ack Vectors, there is no point in allowing endpoints which use CCID2 to disable Ack Vector features such a connection; * a peer with a TX CCID of CCID2 will always expect Ack Vectors, and a peer with a RX CCID of CCID2 must always send Ack Vectors (RFC 4341, sec. 4); * for all other CCIDs, the use of (Send) Ack Vector is optional and thus negotiable. However, this implies that the code negotiating the use of Ack Vectors also supports it (i.e. is able to supply and to either parse or ignore received Ack Vectors). Since this is not the case (CCID-3 has no Ack Vector support), the use of Ack Vectors is here disabled, with a comment in the source code. An analogous consideration arises for the Send Loss Event Rate feature, since the CCID-3 implementation does not support the loss interval options of RFC 4342. To make such use explicit, corresponding feature-negotiation options are inserted which signal the use of the loss event rate option, as it is used by the CCID3 code. Lastly, the values of the Ack Ratio feature are matched to the choice of CCID. The patch implements this as a function which is called after the user has made all other registrations for changing default values of features. The table is variable-length, the reserved (and hence for feature-negotiation invalid, confirmed by considering section 19.4 of RFC 4340) feature number `0' is used to mark the end of the table.

Note: the unlikely case had 71 hits that were more than 25%. Note: After submitting my first version of this patch, Andrew Morton showed me a version written by Daniel Walker, where I picked up the following ideas from: 1) Using __builtin_constant_p to avoid profiling fixed values. 2) Using __FILE__ instead of instruction pointers. 3) Using the preprocessor to stop all profiling of likely annotations from vsyscall_64.c. Thanks to Andrew Morton, Arjan van de Ven, Theodore Tso and Ingo Molnar for their feed back on this patch. (*) Not ever unlikely is recorded, those that are used by vsyscalls (a few of them) had to have profiling disabled.

This patch adds a tracer called "branch" that will just trace the branch profiling. The advantage of adding this tracer is that it can be added to the ftrace selftests on startup.

I've tried to figure out all of the race condition that could happen when the tracer pushes or pops a return address trace to/from the current thread_info. Theory: _ One thread can only execute on one cpu at a time. So this code doesn't need to be SMP-safe. Just drop the spinlock. _ The only race could happen between the current thread and an interrupt. If an interrupt is raised, it will increase the index of the return stack storage and then execute until the end of the tracing to finally free the index it used. We don't need to disable irqs. This is theorical. In practice, I've tested it with a two-core SMP and had no problem at all. Perhaps -tip testing could confirm it.

But we cann't kill netdev->priv, because so many drivers reference to it directly. This patch is a safe convert for netdev->priv to netdev_priv(netdev). Since all of the netdev->priv is only for read. But it is too big to be sent in one mail. I split it to 4 parts and make every part smaller than 100,000 bytes, which is max size allowed by vger.

But we cann't kill netdev->priv, because so many drivers reference to it directly. This patch is a safe convert for netdev->priv to netdev_priv(netdev). Since all of the netdev->priv is only for read. But it is too big to be sent in one mail. I split it to 4 parts and make every part smaller than 100,000 bytes, which is max size allowed by vger.

But we cann't kill netdev->priv, because so many drivers reference to it directly. This patch is a safe convert for netdev->priv to netdev_priv(netdev). Since all of the netdev->priv is only for read. But it is too big to be sent in one mail. I split it to 4 parts and make every part smaller than 100,000 bytes, which is max size allowed by vger.

But we cann't kill netdev->priv, because so many drivers reference to it directly. This patch is a safe convert for netdev->priv to netdev_priv(netdev). Since all of the netdev->priv is only for read. But it is too big to be sent in one mail. I split it to 4 parts and make every part smaller than 100,000 bytes, which is max size allowed by vger.

Kernel developers were confused by the "missing" data of that one CPU at the beginning of the trace output. An annotation was added to the trace output to show that the buffer had started: # tracer: function # # TASK-PID CPU# TIMESTAMP FUNCTION # | | | | | ##### CPU 3 buffer started #### -0 [003] 158.192959: smp_apic_timer_interrupt [...] -0 [003] 161.556520: default_idle ##### CPU 1 buffer started #### -0 [001] 161.592494: hrtimer_force_reprogram [etc] But this annotation gets a bit messy when tracers do not fill the buffers. This patch does a couple of things: One) it adds a flag to trace_options to disable these annotations Two) it does not annotate if the tracer did not overflow its buffer. This makes the output much cleaner.

Currently this specifies a keyring in the target process to link the key into, creating the keyring if it doesn't exist. This, however, can be a problem for copy-on-write credentials as it means that the instantiating process can alter the credentials of the requesting process. This patch alters the behaviour such that: (1) If keyctl_instantiate_key() or keyctl_negate_key() are given a specific keyring by ID (ringid >= 0), then that keyring will be used. (2) If keyctl_instantiate_key() or keyctl_negate_key() are given one of the special constants that refer to the requesting process's keyrings (KEY_SPEC_*_KEYRING, all <= 0), then: (a) If sys_request_key() was given a keyring to use (destringid) then the key will be attached to that keyring. (b) If sys_request_key() was given a NULL keyring, then the key being instantiated will be attached to the default keyring as set by keyctl_set_reqkey_keyring(). (3) No extra link will be made. Decision point (1) follows current behaviour, and allows those instantiators who've searched for a specifically named keyring in the requestor's keyring so as to partition the keys by type to still have their named keyrings. Decision point (2) allows the requestor to make sure that the key or keys that get produced by request_key() go where they want, whilst allowing the instantiator to request that the key is retained. This is mainly useful for situations where the instantiator makes a secondary request, the key for which should be retained by the initial requestor: +-----------+ +--------------+ +--------------+ | | | | | | | Requestor |------->| Instantiator |------->| Instantiator | | | | | | | +-----------+ +--------------+ +--------------+ request_key() request_key() This might be useful, for example, in Kerberos, where the requestor requests a ticket, and then the ticket instantiator requests the TGT, which someone else then has to go and fetch. The TGT, however, should be retained in the keyrings of the requestor, not the first instantiator. To make this explict an extra special keyring constant is also added.

This means that current will not need to lock its own credentials when reading them against interference by other processes. This has effectively been the case for a while anyway, since: (1) Without LSM enabled, sys_capset() is disallowed. (2) With file-based capabilities, sys_capset() is neutered.

This uses RCU to manage the credentials pointer in the task_struct with respect to accesses by other tasks. A process may only modify its own credentials, and so does not need locking to access or modify its own credentials. A mutex (cred_replace_mutex) is added to the task_struct to control the effect of PTRACE_ATTACHED on credential calculations, particularly with respect to execve(). With this patch, the contents of an active credentials struct may not be changed directly; rather a new set of credentials must be prepared, modified and committed using something like the following sequence of events: struct cred *new = prepare_creds(); int ret = blah(new); if (ret < 0) { abort_creds(new); return ret; } return commit_creds(new); There are some exceptions to this rule: the keyrings pointed to by the active credentials may be instantiated - keyrings violate the COW rule as managing COW keyrings is tricky, given that it is possible for a task to directly alter the keys in a keyring in use by another task. To help enforce this, various pointers to sets of credentials, such as those in the task_struct, are declared const. The purpose of this is compile-time discouragement of altering credentials through those pointers. Once a set of credentials has been made public through one of these pointers, it may not be modified, except under special circumstances: (1) Its reference count may incremented and decremented. (2) The keyrings to which it points may be modified, but not replaced. The only safe way to modify anything else is to create a replacement and commit using the functions described in Documentation/credentials.txt (which will be added by a later patch). This patch and the preceding patches have been tested with the LTP SELinux testsuite. This patch makes several logical sets of alteration: (1) execve(). This now prepares and commits credentials in various places in the security code rather than altering the current creds directly. (2) Temporary credential overrides. do_coredump() and sys_faccessat() now prepare their own credentials and temporarily override the ones currently on the acting thread, whilst preventing interference from other threads by holding cred_replace_mutex on the thread being dumped. This will be replaced in a future patch by something that hands down the credentials directly to the functions being called, rather than altering the task's objective credentials. (3) LSM interface. A number of functions have been changed, added or removed: (*) security_capset_check(), ->capset_check() (*) security_capset_set(), ->capset_set() Removed in favour of security_capset(). (*) security_capset(), ->capset() New. This is passed a pointer to the new creds, a pointer to the old creds and the proposed capability sets. It should fill in the new creds or return an error. All pointers, barring the pointer to the new creds, are now const. (*) security_bprm_apply_creds(), ->bprm_apply_creds() Changed; now returns a value, which will cause the process to be killed if it's an error. (*) security_task_alloc(), ->task_alloc_security() Removed in favour of security_prepare_creds(). (*) security_cred_free(), ->cred_free() New. Free security data attached to cred->security. (*) security_prepare_creds(), ->cred_prepare() New. Duplicate any security data attached to cred->security. (*) security_commit_creds(), ->cred_commit() New. Apply any security effects for the upcoming installation of new security by commit_creds(). (*) security_task_post_setuid(), ->task_post_setuid() Removed in favour of security_task_fix_setuid(). (*) security_task_fix_setuid(), ->task_fix_setuid() Fix up the proposed new credentials for setuid(). This is used by cap_set_fix_setuid() to implicitly adjust capabilities in line with setuid() changes. Changes are made to the new credentials, rather than the task itself as in security_task_post_setuid(). (*) security_task_reparent_to_init(), ->task_reparent_to_init() Removed. Instead the task being reparented to init is referred directly to init's credentials. NOTE! This results in the loss of some state: SELinux's osid no longer records the sid of the thread that forked it. (*) security_key_alloc(), ->key_alloc() (*) security_key_permission(), ->key_permission() Changed. These now take cred pointers rather than task pointers to refer to the security context. (4) sys_capset(). This has been simplified and uses less locking. The LSM functions it calls have been merged. (5) reparent_to_kthreadd(). This gives the current thread the same credentials as init by simply using commit_thread() to point that way. (6) __sigqueue_alloc() and switch_uid() __sigqueue_alloc() can't stop the target task from changing its creds beneath it, so this function gets a reference to the currently applicable user_struct which it then passes into the sigqueue struct it returns if successful. switch_uid() is now called from commit_creds(), and possibly should be folded into that. commit_creds() should take care of protecting __sigqueue_alloc(). (7) [sg]et[ug]id() and co and [sg]et_current_groups. The set functions now all use prepare_creds(), commit_creds() and abort_creds() to build and check a new set of credentials before applying it. security_task_set[ug]id() is called inside the prepared section. This guarantees that nothing else will affect the creds until we've finished. The calling of set_dumpable() has been moved into commit_creds(). Much of the functionality of set_user() has been moved into commit_creds(). The get functions all simply access the data directly. (8) security_task_prctl() and cap_task_prctl(). security_task_prctl() has been modified to return -ENOSYS if it doesn't want to handle a function, or otherwise return the return value directly rather than through an argument. Additionally, cap_task_prctl() now prepares a new set of credentials, even if it doesn't end up using it. (9) Keyrings. A number of changes have been made to the keyrings code: (a) switch_uid_keyring(), copy_keys(), exit_keys() and suid_keys() have all been dropped and built in to the credentials functions directly. They may want separating out again later. (b) key_alloc() and search_process_keyrings() now take a cred pointer rather than a task pointer to specify the security context. (c) copy_creds() gives a new thread within the same thread group a new thread keyring if its parent had one, otherwise it discards the thread keyring. (d) The authorisation key now points directly to the credentials to extend the search into rather pointing to the task that carries them. (e) Installing thread, process or session keyrings causes a new set of credentials to be created, even though it's not strictly necessary for process or session keyrings (they're shared). (10) Usermode helper. The usermode helper code now carries a cred struct pointer in its subprocess_info struct instead of a new session keyring pointer. This set of credentials is derived from init_cred and installed on the new process after it has been cloned. call_usermodehelper_setup() allocates the new credentials and call_usermodehelper_freeinfo() discards them if they haven't been used. A special cred function (prepare_usermodeinfo_creds()) is provided specifically for call_usermodehelper_setup() to call. call_usermodehelper_setkeys() adjusts the credentials to sport the supplied keyring as the new session keyring. (11) SELinux. SELinux has a number of changes, in addition to those to support the LSM interface changes mentioned above: (a) selinux_setprocattr() no longer does its check for whether the current ptracer can access processes with the new SID inside the lock that covers getting the ptracer's SID. Whilst this lock ensures that the check is done with the ptracer pinned, the result is only valid until the lock is released, so there's no point doing it inside the lock. (12) is_single_threaded(). This function has been extracted from selinux_setprocattr() and put into a file of its own in the lib/ directory as join_session_keyring() now wants to use it too. The code in SELinux just checked to see whether a task shared mm_structs with other tasks (CLONE_VM), but that isn't good enough. We really want to know if they're part of the same thread group (CLONE_THREAD). (13) nfsd. The NFS server daemon now has to use the COW credentials to set the credentials it is going to use. It really needs to pass the credentials down to the functions it calls, but it can't do that until other patches in this series have been applied.

This patch and the preceding patches have been tested with the LTP SELinux testsuite. This patch makes several logical sets of alteration: (1) execve(). The credential bits from struct linux_binprm are, for the most part, replaced with a single credentials pointer (bprm->cred). This means that all the creds can be calculated in advance and then applied at the point of no return with no possibility of failure. I would like to replace bprm->cap_effective with: cap_isclear(bprm->cap_effective) but this seems impossible due to special behaviour for processes of pid 1 (they always retain their parent's capability masks where normally they'd be changed - see cap_bprm_set_creds()). The following sequence of events now happens: (a) At the start of do_execve, the current task's cred_exec_mutex is locked to prevent PTRACE_ATTACH from obsoleting the calculation of creds that we make. (a) prepare_exec_creds() is then called to make a copy of the current task's credentials and prepare it. This copy is then assigned to bprm->cred. This renders security_bprm_alloc() and security_bprm_free() unnecessary, and so they've been removed. (b) The determination of unsafe execution is now performed immediately after (a) rather than later on in the code. The result is stored in bprm->unsafe for future reference. (c) prepare_binprm() is called, possibly multiple times. (i) This applies the result of set[ug]id binaries to the new creds attached to bprm->cred. Personality bit clearance is recorded, but now deferred on the basis that the exec procedure may yet fail. (ii) This then calls the new security_bprm_set_creds(). This should calculate the new LSM and capability credentials into *bprm->cred. This folds together security_bprm_set() and parts of security_bprm_apply_creds() (these two have been removed). Anything that might fail must be done at this point. (iii) bprm->cred_prepared is set to 1. bprm->cred_prepared is 0 on the first pass of the security calculations, and 1 on all subsequent passes. This allows SELinux in (ii) to base its calculations only on the initial script and not on the interpreter. (d) flush_old_exec() is called to commit the task to execution. This performs the following steps with regard to credentials: (i) Clear pdeath_signal and set dumpable on certain circumstances that may not be covered by commit_creds(). (ii) Clear any bits in current->personality that were deferred from (c.i). (e) install_exec_creds() [compute_creds() as was] is called to install the new credentials. This performs the following steps with regard to credentials: (i) Calls security_bprm_committing_creds() to apply any security requirements, such as flushing unauthorised files in SELinux, that must be done before the credentials are changed. This is made up of bits of security_bprm_apply_creds() and security_bprm_post_apply_creds(), both of which have been removed. This function is not allowed to fail; anything that might fail must have been done in (c.ii). (ii) Calls commit_creds() to apply the new credentials in a single assignment (more or less). Possibly pdeath_signal and dumpable should be part of struct creds. (iii) Unlocks the task's cred_replace_mutex, thus allowing PTRACE_ATTACH to take place. (iv) Clears The bprm->cred pointer as the credentials it was holding are now immutable. (v) Calls security_bprm_committed_creds() to apply any security alterations that must be done after the creds have been changed. SELinux uses this to flush signals and signal handlers. (f) If an error occurs before (d.i), bprm_free() will call abort_creds() to destroy the proposed new credentials and will then unlock cred_replace_mutex. No changes to the credentials will have been made. (2) LSM interface. A number of functions have been changed, added or removed: (*) security_bprm_alloc(), ->bprm_alloc_security() (*) security_bprm_free(), ->bprm_free_security() Removed in favour of preparing new credentials and modifying those. (*) security_bprm_apply_creds(), ->bprm_apply_creds() (*) security_bprm_post_apply_creds(), ->bprm_post_apply_creds() Removed; split between security_bprm_set_creds(), security_bprm_committing_creds() and security_bprm_committed_creds(). (*) security_bprm_set(), ->bprm_set_security() Removed; folded into security_bprm_set_creds(). (*) security_bprm_set_creds(), ->bprm_set_creds() New. The new credentials in bprm->creds should be checked and set up as appropriate. bprm->cred_prepared is 0 on the first call, 1 on the second and subsequent calls. (*) security_bprm_committing_creds(), ->bprm_committing_creds() (*) security_bprm_committed_creds(), ->bprm_committed_creds() New. Apply the security effects of the new credentials. This includes closing unauthorised files in SELinux. This function may not fail. When the former is called, the creds haven't yet been applied to the process; when the latter is called, they have. The former may access bprm->cred, the latter may not. (3) SELinux. SELinux has a number of changes, in addition to those to support the LSM interface changes mentioned above: (a) The bprm_security_struct struct has been removed in favour of using the credentials-under-construction approach. (c) flush_unauthorized_files() now takes a cred pointer and passes it on to inode_has_perm(), file_has_perm() and dentry_open().

Processes/tasks are the obvious exception: + they do stuff; they access and manipulate things. + + Objects other than tasks may under some circumstances also be subjects. + For instance an open file may send SIGIO to a task using the UID and EUID + given to it by a task that called fcntl(F_SETOWN) upon it. In this case, + the file struct will have a subjective context too. + + (5) The subjective context. + + A subject has an additional interpretation of its credentials. A subset + of its credentials forms the 'subjective context'. The subjective context + is used as part of the security calculation that is carried out when a + subject acts. + + A Linux task, for example, has the FSUID, FSGID and the supplementary + group list for when it is acting upon a file - which are quite separate + from the real UID and GID that normally form the objective context of the + task. + + (6) Actions. + + Linux has a number of actions available that a subject may perform upon an + object. The set of actions available depends on the nature of the subject + and the object. + + Actions include reading, writing, creating and deleting files; forking or + signalling and tracing tasks. + + (7) Rules, access control lists and security calculations. + + When a subject acts upon an object, a security calculation is made. This + involves taking the subjective context, the objective context and the + action, and searching one or more sets of rules to see whether the subject + is granted or denied permission to act in the desired manner on the + object, given those contexts. + + There are two main sources of rules: + + (a) Discretionary access control (DAC): + + Sometimes the object will include sets of rules as part of its + description. This is an 'Access Control List' or 'ACL'. A Linux + file may supply more than one ACL. + + A traditional UNIX file, for example, includes a permissions mask that + is an abbreviated ACL with three fixed classes of subject ('user', + 'group' and 'other'), each of which may be granted certain privileges + ('read', 'write' and 'execute' - whatever those map to for the object + in question). UNIX file permissions do not allow the arbitrary + specification of subjects, however, and so are of limited use. + + A Linux file might also sport a POSIX ACL. This is a list of rules + that grants various permissions to arbitrary subjects. + + (b) Mandatory access control (MAC): + + The system as a whole may have one or more sets of rules that get + applied to all subjects and objects, regardless of their source. + SELinux and Smack are examples of this. + + In the case of SELinux and Smack, each object is given a label as part + of its credentials. When an action is requested, they take the + subject label, the object label and the action and look for a rule + that says that this action is either granted or denied. + + +==================== +TYPES OF CREDENTIALS +==================== + +The Linux kernel supports the following types of credentials: + + (1) Traditional UNIX credentials. + + Real User ID + Real Group ID + + The UID and GID are carried by most, if not all, Linux objects, even if in + some cases it has to be invented (FAT or CIFS files for example, which are + derived from Windows). These (mostly) define the objective context of + that object, with tasks being slightly different in some cases. + + Effective, Saved and FS User ID + Effective, Saved and FS Group ID + Supplementary groups + + These are additional credentials used by tasks only. Usually, an + EUID/EGID/GROUPS will be used as the subjective context, and real UID/GID + will be used as the objective. For tasks, it should be noted that this is + not always true. + + (2) Capabilities. + + Set of permitted capabilities + Set of inheritable capabilities + Set of effective capabilities + Capability bounding set + + These are only carried by tasks. They indicate superior capabilities + granted piecemeal to a task that an ordinary task wouldn't otherwise have. + These are manipulated implicitly by changes to the traditional UNIX + credentials, but can also be manipulated directly by the capset() system + call. + + The permitted capabilities are those caps that the process might grant + itself to its effective or permitted sets through capset(). This + inheritable set might also be so constrained. + + The effective capabilities are the ones that a task is actually allowed to + make use of itself. + + The inheritable capabilities are the ones that may get passed across + execve(). + + The bounding set limits the capabilities that may be inherited across + execve(), especially when a binary is executed that will execute as UID 0. + + (3) Secure management flags (securebits). + + These are only carried by tasks. These govern the way the above + credentials are manipulated and inherited over certain operations such as + execve(). They aren't used directly as objective or subjective + credentials. + + (4) Keys and keyrings. + + These are only carried by tasks. They carry and cache security tokens + that don't fit into the other standard UNIX credentials. They are for + making such things as network filesystem keys available to the file + accesses performed by processes, without the necessity of ordinary + programs having to know about security details involved. + + Keyrings are a special type of key. They carry sets of other keys and can + be searched for the desired key. Each process may subscribe to a number + of keyrings: + + Per-thread keying + Per-process keyring + Per-session keyring + + When a process accesses a key, if not already present, it will normally be + cached on one of these keyrings for future accesses to find. + + For more information on using keys, see Documentation/keys.txt. + + (5) LSM + + The Linux Security Module allows extra controls to be placed over the + operations that a task may do. Currently Linux supports two main + alternate LSM options: SELinux and Smack. + + Both work by labelling the objects in a system and then applying sets of + rules (policies) that say what operations a task with one label may do to + an object with another label. + + (6) AF_KEY + + This is a socket-based approach to credential management for networking + stacks [RFC 2367]. It isn't discussed by this document as it doesn't + interact directly with task and file credentials; rather it keeps system + level credentials. + + +When a file is opened, part of the opening task's subjective context is +recorded in the file struct created. This allows operations using that file +struct to use those credentials instead of the subjective context of the task +that issued the operation. An example of this would be a file opened on a +network filesystem where the credentials of the opened file should be presented +to the server, regardless of who is actually doing a read or a write upon it. + + +============= +FILE MARKINGS +============= + +Files on disk or obtained over the network may have annotations that form the +objective security context of that file. Depending on the type of filesystem, +this may include one or more of the following: + + (*) UNIX UID, GID, mode; + + (*) Windows user ID; + + (*) Access control list; + + (*) LSM security label; + + (*) UNIX exec privilege escalation bits (SUID/SGID); + + (*) File capabilities exec privilege escalation bits. + +These are compared to the task's subjective security context, and certain +operations allowed or disallowed as a result. In the case of execve(), the +privilege escalation bits come into play, and may allow the resulting process +extra privileges, based on the annotations on the executable file. + + +================ +TASK CREDENTIALS +================ + +In Linux, all of a task's credentials are held in (uid, gid) or through +(groups, keys, LSM security) a refcounted structure of type 'struct cred'. +Each task points to its credentials by a pointer called 'cred' in its +task_struct. + +Once a set of credentials has been prepared and committed, it may not be +changed, barring the following exceptions: + + (1) its reference count may be changed; + + (2) the reference count on the group_info struct it points to may be changed; + + (3) the reference count on the security data it points to may be changed; + + (4) the reference count on any keyrings it points to may be changed; + + (5) any keyrings it points to may be revoked, expired or have their security + attributes changed; and + + (6) the contents of any keyrings to which it points may be changed (the whole + point of keyrings being a shared set of credentials, modifiable by anyone + with appropriate access). + +To alter anything in the cred struct, the copy-and-replace principle must be +adhered to. First take a copy, then alter the copy and then use RCU to change +the task pointer to make it point to the new copy. There are wrappers to aid +with this (see below). + +A task may only alter its _own_ credentials; it is no longer permitted for a +task to alter another's credentials. This means the capset() system call is no +longer permitted to take any PID other than the one of the current process. +Also keyctl_instantiate() and keyctl_negate() functions no longer permit +attachment to process-specific keyrings in the requesting process as the +instantiating process may need to create them. + + +IMMUTABLE CREDENTIALS +--------------------- + +Once a set of credentials has been made public (by calling commit_creds() for +example), it must be considered immutable, barring two exceptions: + + (1) The reference count may be altered. + + (2) Whilst the keyring subscriptions of a set of credentials may not be + changed, the keyrings subscribed to may have their contents altered. + +To catch accidental credential alteration at compile time, struct task_struct +has _const_ pointers to its credential sets, as does struct file. Furthermore, +certain functions such as get_cred() and put_cred() operate on const pointers, +thus rendering casts unnecessary, but require to temporarily ditch the const +qualification to be able to alter the reference count. + + +ACCESSING TASK CREDENTIALS +-------------------------- + +A task being able to alter only its own credentials permits the current process +to read or replace its own credentials without the need for any form of locking +- which simplifies things greatly. It can just call: + + const struct cred *current_cred() + +to get a pointer to its credentials structure, and it doesn't have to release +it afterwards. + +There are convenience wrappers for retrieving specific aspects of a task's +credentials (the value is simply returned in each case): + + uid_t current_uid(void) Current's real UID + gid_t current_gid(void) Current's real GID + uid_t current_euid(void) Current's effective UID + gid_t current_egid(void) Current's effective GID + uid_t current_fsuid(void) Current's file access UID + gid_t current_fsgid(void) Current's file access GID + kernel_cap_t current_cap(void) Current's effective capabilities + void *current_security(void) Current's LSM security pointer + struct user_struct *current_user(void) Current's user account + +There are also convenience wrappers for retrieving specific associated pairs of +a task's credentials: + + void current_uid_gid(uid_t *, gid_t *); + void current_euid_egid(uid_t *, gid_t *); + void current_fsuid_fsgid(uid_t *, gid_t *); + +which return these pairs of values through their arguments after retrieving +them from the current task's credentials. + + +In addition, there is a function for obtaining a reference on the current +process's current set of credentials: + + const struct cred *get_current_cred(void); + +and functions for getting references to one of the credentials that don't +actually live in struct cred: + + struct user_struct *get_current_user(void); + struct group_info *get_current_groups(void); + +which get references to the current process's user accounting structure and +supplementary groups list respectively. + +Once a reference has been obtained, it must be released with put_cred(), +free_uid() or put_group_info() as appropriate. + + +ACCESSING ANOTHER TASK'S CREDENTIALS +------------------------------------ + +Whilst a task may access its own credentials without the need for locking, the +same is not true of a task wanting to access another task's credentials. It +must use the RCU read lock and rcu_dereference(). + +The rcu_dereference() is wrapped by: + + const struct cred *__task_cred(struct task_struct *task); + +This should be used inside the RCU read lock, as in the following example: + + void foo(struct task_struct *t, struct foo_data *f) + { + const struct cred *tcred; + ... + rcu_read_lock(); + tcred = __task_cred(t); + f->uid = tcred->uid; + f->gid = tcred->gid; + f->groups = get_group_info(tcred->groups); + rcu_read_unlock(); + ... + } + +A function need not get RCU read lock to use __task_cred() if it is holding a +spinlock at the time as this implicitly holds the RCU read lock. + +Should it be necessary to hold another task's credentials for a long period of +time, and possibly to sleep whilst doing so, then the caller should get a +reference on them using: + + const struct cred *get_task_cred(struct task_struct *task); + +This does all the RCU magic inside of it. The caller must call put_cred() on +the credentials so obtained when they're finished with. + +There are a couple of convenience functions to access bits of another task's +credentials, hiding the RCU magic from the caller: + + uid_t task_uid(task) Task's real UID + uid_t task_euid(task) Task's effective UID + +If the caller is holding a spinlock or the RCU read lock at the time anyway, +then: + + __task_cred(task)->uid + __task_cred(task)->euid + +should be used instead. Similarly, if multiple aspects of a task's credentials +need to be accessed, RCU read lock or a spinlock should be used, __task_cred() +called, the result stored in a temporary pointer and then the credential +aspects called from that before dropping the lock. This prevents the +potentially expensive RCU magic from being invoked multiple times. + +Should some other single aspect of another task's credentials need to be +accessed, then this can be used: + + task_cred_xxx(task, member) + +where 'member' is a non-pointer member of the cred struct. For instance: + + uid_t task_cred_xxx(task, suid); + +will retrieve 'struct cred::suid' from the task, doing the appropriate RCU +magic. This may not be used for pointer members as what they point to may +disappear the moment the RCU read lock is dropped. + + +ALTERING CREDENTIALS +-------------------- + +As previously mentioned, a task may only alter its own credentials, and may not +alter those of another task. This means that it doesn't need to use any +locking to alter its own credentials. + +To alter the current process's credentials, a function should first prepare a +new set of credentials by calling: + + struct cred *prepare_creds(void); + +this locks current->cred_replace_mutex and then allocates and constructs a +duplicate of the current process's credentials, returning with the mutex still +held if successful. It returns NULL if not successful (out of memory). + +The mutex prevents ptrace() from altering the ptrace state of a process whilst +security checks on credentials construction and changing is taking place as +the ptrace state may alter the outcome, particularly in the case of execve(). + +The new credentials set should be altered appropriately, and any security +checks and hooks done. Both the current and the proposed sets of credentials +are available for this purpose as current_cred() will return the current set +still at this point. + + +When the credential set is ready, it should be committed to the current process +by calling: + + int commit_creds(struct cred *new); + +This will alter various aspects of the credentials and the process, giving the +LSM a chance to do likewise, then it will use rcu_assign_pointer() to actually +commit the new credentials to current->cred, it will release +current->cred_replace_mutex to allow ptrace() to take place, and it will notify +the scheduler and others of the changes. + +This function is guaranteed to return 0, so that it can be tail-called at the +end of such functions as sys_setresuid(). + +Note that this function consumes the caller's reference to the new credentials. +The caller should _not_ call put_cred() on the new credentials afterwards. + +Furthermore, once this function has been called on a new set of credentials, +those credentials may _not_ be changed further. + + +Should the security checks fail or some other error occur after prepare_creds() +has been called, then the following function should be invoked: + + void abort_creds(struct cred *new); + +This releases the lock on current->cred_replace_mutex that prepare_creds() got +and then releases the new credentials. + + +A typical credentials alteration function would look something like this: + + int alter_suid(uid_t suid) + { + struct cred *new; + int ret; + + new = prepare_creds(); + if (!new) + return -ENOMEM; + + new->suid = suid; + ret = security_alter_suid(new); + if (ret < 0) { + abort_creds(new); + return ret; + } + + return commit_creds(new); + } + + +MANAGING CREDENTIALS +-------------------- + +There are some functions to help manage credentials: + + (*) void put_cred(const struct cred *cred); + + This releases a reference to the given set of credentials. If the + reference count reaches zero, the credentials will be scheduled for + destruction by the RCU system. + + (*) const struct cred *get_cred(const struct cred *cred); + + This gets a reference on a live set of credentials, returning a pointer to + that set of credentials. + + (*) struct cred *get_new_cred(struct cred *cred); + + This gets a reference on a set of credentials that is under construction + and is thus still mutable, returning a pointer to that set of credentials. + + +===================== +OPEN FILE CREDENTIALS +===================== + +When a new file is opened, a reference is obtained on the opening task's +credentials and this is attached to the file struct as 'f_cred' in place of +'f_uid' and 'f_gid'. Code that used to access file->f_uid and file->f_gid +should now access file->f_cred->fsuid and file->f_cred->fsgid. + +It is safe to access f_cred without the use of RCU or locking because the +pointer will not change over the lifetime of the file struct, and nor will the +contents of the cred struct pointed to, barring the exceptions listed above +(see the Task Credentials section). + + +======================================= +OVERRIDING THE VFS'S USE OF CREDENTIALS +======================================= + +Under some circumstances it is desirable to override the credentials used by +the VFS, and that can be done by calling into such as vfs_mkdir() with a +different set of credentials. This is done in the following places: + + (*) sys_faccessat(). + + (*) do_coredump(). + + (*) nfs4recover.c. diff --git a/include/linux/cred.h b/include/linux/cred.h index 8edb4d1..794aab5 100644 --- a/include/linux/cred.h +++ b/include/linux/cred.h @@ -1,4 +1,4 @@ -/* Credentials management +/* Credentials management - see Documentation/credentials.txt * * Copyright (C) 2008 Red Hat, Inc.

These are not visible to the other tasks in the system. __task_cred(task) then refers to the objective/real credentials of the task in question. current_cred() refers to the effective subjective credentials of the current task. prepare_creds() uses the objective creds as a base and commit_creds() changes both pointers in the task_struct (indeed commit_creds() requires them to be the same). override_creds() and revert_creds() change the subjective creds pointer only, and the former returns the old subjective creds. These are used by NFSD, faccessat() and do_coredump(), and will by used by CacheFiles. In SELinux, current_has_perm() is provided as an alternative to task_has_perm(). This uses the effective subjective context of current, whereas task_has_perm() uses the objective/real context of the subject.

The first vector is used to grant a process the right to nominate an alternate process security ID for the kernel to use as an override for the SELinux subjective security when accessing stuff on behalf of another process. For example, CacheFiles when accessing the cache on behalf on a process accessing an NFS file needs to use a subjective security ID appropriate to the cache rather then the one the calling process is using. The cachefilesd daemon will nominate the security ID to be used. The second vector is used to grant a process the right to nominate a file creation label for a kernel service to use.

This is used, for example, by CacheFiles which has to transparently access the cache on behalf of a process that thinks it is doing, say, NFS accesses with a potentially inappropriate (with respect to accessing the cache) set of credentials. This patch provides two LSM hooks for modifying a task security record: (*) security_kernel_act_as() which allows modification of the security datum with which a task acts on other objects (most notably files). (*) security_kernel_create_files_as() which allows modification of the security datum that is used to initialise the security data on a file that a task creates. The patch also provides four new credentials handling functions, which wrap the LSM functions: (1) prepare_kernel_cred() Prepare a set of credentials for a kernel service to use, based either on a daemon's credentials or on init_cred. All the keyrings are cleared. (2) set_security_override() Set the LSM security ID in a set of credentials to a specific security context, assuming permission from the LSM policy. (3) set_security_override_from_ctx() As (2), but takes the security context as a string. (4) set_create_files_as() Set the file creation LSM security ID in a set of credentials to be the same as that on a particular inode.

Christian Pellegrin reported that on some systems the patch caused DMA to fail which is much more serious than the original skipped audio issue. Further investigation by Dave shows that the behaviour depends on the clock speed of the SoC - a better fix is neeeded.

Since x86 does not have the same limitations as other architectures, the ftrace interaction between the generic code and the architecture specific code was not flexible enough to handle some of the issues that other architectures have. Most notably, module trampolines. Due to the limited branch distance that archs make in calling kernel core code from modules, the module load code must create a trampoline to jump to what will make the larger jump into core kernel code. The problem arises when this happens to a call to mcount. Ftrace checks all code before modifying it and makes sure the current code is what it expects. Right now, there is not enough information to handle modifying module trampolines. This patch changes the API between generic dynamic ftrace code and the arch dependent code. There is now two functions for modifying code: ftrace_make_nop(mod, rec, addr) - convert the code at rec->ip into a nop, where the original text is calling addr. (mod is the module struct if called by module init) ftrace_make_caller(rec, addr) - convert the code rec->ip that should be a nop into a caller to addr. The record "rec" now has a new field called "arch" where the architecture can add any special attributes to each call site record.

The whole difference with normal dynamic function tracing is that we don't need to hook on a particular callback. The only pro that we want is to nop or set dynamically the calls to ftrace_caller (which is ftrace_return_caller here). Some security checks ensure that we are not trying to launch dynamic tracing for return tracing while normal function tracing is already running. An example of trace with getnstimeofday set as a filter: ktime_get_ts+0x22/0x50 -> getnstimeofday (2283 ns) ktime_get_ts+0x22/0x50 -> getnstimeofday (1396 ns) ktime_get_ts+0x22/0x50 -> getnstimeofday (1382 ns) ktime_get_ts+0x22/0x50 -> getnstimeofday (1825 ns) ktime_get_ts+0x22/0x50 -> getnstimeofday (1426 ns) ktime_get_ts+0x22/0x50 -> getnstimeofday (1464 ns) ktime_get_ts+0x22/0x50 -> getnstimeofday (1524 ns) ktime_get_ts+0x22/0x50 -> getnstimeofday (1382 ns) ktime_get_ts+0x22/0x50 -> getnstimeofday (1382 ns) ktime_get_ts+0x22/0x50 -> getnstimeofday (1434 ns) ktime_get_ts+0x22/0x50 -> getnstimeofday (1464 ns) ktime_get_ts+0x22/0x50 -> getnstimeofday (1502 ns) ktime_get_ts+0x22/0x50 -> getnstimeofday (1404 ns) ktime_get_ts+0x22/0x50 -> getnstimeofday (1397 ns) ktime_get_ts+0x22/0x50 -> getnstimeofday (1051 ns) ktime_get_ts+0x22/0x50 -> getnstimeofday (1314 ns) ktime_get_ts+0x22/0x50 -> getnstimeofday (1344 ns) ktime_get_ts+0x22/0x50 -> getnstimeofday (1163 ns) ktime_get_ts+0x22/0x50 -> getnstimeofday (1390 ns) ktime_get_ts+0x22/0x50 -> getnstimeofday (1374 ns) Signed-off-by: Frederic Weisbecker Signed-off-by: Ingo Molnar diff --git a/arch/x86/kernel/entry_32.S b/arch/x86/kernel/entry_32.S index f976211..74defe2 100644 --- a/arch/x86/kernel/entry_32.S +++ b/arch/x86/kernel/entry_32.S @@ -1190,7 +1190,7 @@ ENTRY(mcount) jnz trace #ifdef CONFIG_FUNCTION_RET_TRACER cmpl $ftrace_stub, ftrace_function_return - jnz trace_return + jnz ftrace_return_caller #endif .globl ftrace_stub ftrace_stub: @@ -1211,9 +1211,15 @@ trace: popl %ecx popl %eax jmp ftrace_stub +END(mcount) +#endif /* CONFIG_DYNAMIC_FTRACE */ +#endif /* CONFIG_FUNCTION_TRACER */ #ifdef CONFIG_FUNCTION_RET_TRACER -trace_return: +ENTRY(ftrace_return_caller) + cmpl $0, function_trace_stop + jne ftrace_stub + pushl %eax pushl %ecx pushl %edx @@ -1223,7 +1229,8 @@ trace_return: popl %edx popl %ecx popl %eax - jmp ftrace_stub + ret +END(ftrace_return_caller) .globl return_to_handler return_to_handler: @@ -1237,10 +1244,7 @@ return_to_handler: popl %ecx popl %eax ret -#endif /* CONFIG_FUNCTION_RET_TRACER */ -END(mcount) -#endif /* CONFIG_DYNAMIC_FTRACE */ -#endif /* CONFIG_FUNCTION_TRACER */ +#endif .section .rodata,"a" #include "syscall_table_32.S" diff --git a/arch/x86/kernel/ftrace.c b/arch/x86/kernel/ftrace.c index d98b5a8..924153e 100644 --- a/arch/x86/kernel/ftrace.c +++ b/arch/x86/kernel/ftrace.c @@ -24,134 +24,6 @@ #include - -#ifdef CONFIG_FUNCTION_RET_TRACER - -/* - * These functions are picked from those used on - * this page for dynamic ftrace.

Must update all tracepoint users. Add DEFINE_TRACE() to tracepoints to let them declare the tracepoint structure in a single spot for all the kernel. It helps reducing memory consumption, especially when declaring a lot of tracepoints, e.g. for kmalloc tracing. *API CHANGE WARNING*: now, DECLARE_TRACE() must be used in headers for tracepoint declarations rather than DEFINE_TRACE().

Aditional changes to mdio-gpio: - use gpio_request() and gpio_free() - place irq[] array in struct mdio_gpio_info - add module description, author and license - add note about compiling this driver as module - rename mdc and mdio function (were ugly names) - change MII to MDIO in bus name - add __init __exit to module (un)loading functions - probe fails if no phys added to the bus - kzalloc bitbang with sizeof(*bitbang) Changes since v3: - keep bus naming "%x" to be compatible with existing drivers. Changes since v2: - more #ifdefs reduction - platform driver will be registered on OF platforms also - unified platform and OF bus_id to phy%i Changes since v1: - removed NO_IRQ - reduced #idefs Laurent, please test this driver under OF.

RCUification already done on UDP two weeks ago. Using hlist_nulls permits us to avoid some memory barriers, both at lookup time and delete time. Patch is large because it adds new macros to include/net/sock.h. These macros will be used by TCP & DCCP in next patch. Signed-off-by: Eric Dumazet Signed-off-by: David S.

This patch uses same infrastructure for TCP/DCCP established and timewait sockets. Thanks to SLAB_DESTROY_BY_RCU, no slowdown for applications using short lived TCP connections. A followup patch, converting rwlocks to spinlocks will even speedup this case. __inet_lookup_established() is pretty fast now we dont have to dirty a contended cache line (read_lock/read_unlock) Only established and timewait hashtable are converted to RCU (bind table and listen table are still using traditional locking) Signed-off-by: Eric Dumazet Signed-off-by: David S.

We cannot use __atribute((aligned)), so manually pad the structure for 32 and 64 bit arches. for 32bit : offsetof(truct dst_entry, __refcnt) is 0x80 for 64bit : offsetof(truct dst_entry, __refcnt) is 0xc0 As it is not possible to guess at compile time cache line size, we use a generic value of 64 bytes, that satisfies many current arches. (Using 128 bytes alignment on 64bit arches would waste 64 bytes) Add a BUILD_BUG_ON to catch future updates to "struct dst_entry" dont break this alignment.

This uses up 20 ring entries, allowing us to supply only 20 packet buffers to the host with a 256 entry ring. This is a huge overhead when receiving small packets, and is most keenly felt when receiving MTU sized packets from off-host. The VIRTIO_NET_F_MRG_RXBUF feature flag is set by hosts which support using receive buffers which are smaller than the maximum packet size. In order to transfer large packets to the guest, the host merges together multiple receive buffers to form a larger logical buffer. The number of merged buffers is returned to the guest via a field in the virtio_net_hdr. Make use of this support by supplying single page receive buffers to the host. On receive, we extract the virtio_net_hdr, copy 128 bytes of the payload to the skb's linear data buffer and adjust the fragment offset to point to the remaining data. This ensures proper alignment and allows us to not use any paged data for small packets. If the payload occupies multiple pages, we simply append those pages as fragments and free the associated skbs. This scheme allows us to be efficient in our use of ring entries while still supporting large packets. Benchmarking using netperf from an external machine to a guest over a 10Gb/s network shows a 100% improvement from ~1Gb/s to ~2Gb/s. With a local host->guest benchmark with GSO disabled on the host side, throughput was seen to increase from 700Mb/s to 1.7Gb/s. Based on a patch from Herbert Xu.

Continuing to support it leads to ugly code since the old approach did not distinguish between NN and SP values. This patch removes the old setsockopt interface and replaces it with two new functions to register NN/SP values for feature negotiation. These are essentially wrappers around the internal __feat_register functions, with checking added to avoid * wrong usage (type); * changing values while the connection is in progress.

Feature-negotiation options are now generated for both sender and receiver coverage, i.e. when the peer has `forgotten' to enable partial coverage then feature negotiation will automatically enable (negotiate) the partial coverage value for this connection.

The only reasonable place for Ack Ratio is to print it for debugging. It is planned to do this later on, as part of e.g. dccp_probe. With this patch Ack Ratio is now under full control of feature negotiation: * Ack Ratio is resolved as a dependency of the selected CCID; * if the chosen CCID supports it (i.e. CCID == CCID-2), Ack Ratio is set to the default of 2, following RFC 4340, 11.3 - "New connections start with Ack Ratio 2 for both endpoints"; * what happens then is part of another patch set, since it concerns the dynamic update of Ack Ratio while the connection is in full flight.

So NUMAQ is using wrong wakeup_secondary_cpu. WAKE_SECONDARY_VIA_NMI, WAKE_SECONDARY_VIA_INIT and WAKE_SECONDARY_VIA_MIP are variants of a weird and fragile preprocessor-driven "HAL" mechanisms to specify the kind of secondary-CPU wakeup strategy a given x86 kernel will use. The vast majority of systems want to use INIT for secondary wakeup - NUMAQ uses an NMI, (old-style-) ES7000 uses 'MIP' (a firmware driven in-memory flag to let secondaries continue). So convert these mechanisms to x86_quirks and add a ->wakeup_secondary_cpu() method to specify the rare exception to the sane default. Extend genapic accordingly as well, for 32-bit. While looking further, I noticed that functions in wakecup.h for numaq and es7000 are different to the default in mach_wakecpu.h - but smpboot.c will only use default mach_wakecpu.h with smphook.h. So we need to add mach_wakecpu.h for mach_generic, to properly support numaq and es7000, and vectorize the following SMP init methods: int trampoline_phys_low; int trampoline_phys_high; void (*wait_for_init_deassert)(atomic_t *deassert); void (*smp_callin_clear_local_apic)(void); void (*store_NMI_vector)(unsigned short *high, unsigned short *low); void (*restore_NMI_vector)(unsigned short *high, unsigned short *low); void (*inquire_remote_apic)(int apicid);

Some notes: - Shall we show an empty file if the ELD content is not valid? Well it's not that simple. There could be partially populated ELD, and there may be malformed ELD provided by buggy drivers/monitors. So expose ELD as it is. - The ELD retrieval routines rely on the Intel HDA interface, others are/could be universal and independent ones. - How do we name the proc file? If there are going to be two HDMI pins per codec, then the current naming scheme (eld#) will fail. Luckily the user space dependencies should be minimal, so it would be trivial to do the rename if that happens. - The ELD proc file content is designed to be easy for scripts and human reading. Its lines all have the pattern: \t[\t]* where is a keyword in c language, while could be any contents, including white spaces. could also be a null value.

But we have no way to implement custom flags handling for a specific tracer. This patch proposes a new callback for the struct tracer which called set_flag and a structure that represents a 32 bits variable flag. A tracer can implement a struct tracer_flags on which it puts the initial value of the flag integer. Than it can place a range of flags with their name and their flag mask on the flag integer. The structure that implement a single flag is called struct tracer_opt. These custom flags will be available through the trace_options file like the general tracing flags. Changing their value is done like the other general flags. For example if you have a flag that calls "foo", you can activate it by writing "foo" or "nofoo" on trace_options. Note that the set_flag callback is optional and is only needed if you want the flags changing to be signaled to your tracer and let it to accept or refuse their assignment. V2: Some arrangements in coding style....

This can result in inconsistent situations if several userspace processes modify the connection tracking table by means of ctnetlink at the same time. Specifically, using the conntrack command line tool and conntrackd at the same time can trigger unconsistencies. This patch also modifies the event cache infrastructure to pass the process PID and the ECHO flag to nfnetlink_send() to report back to userspace if the process that triggered the change needs so. Based on a suggestion from Patrick McHardy.

After all its just that they get called from non-preemptible context: kernel_init() will execute all initcalls, however the first line in kernel_init() is lock_kernel(), which causes the preempt_count to be increased. Any later calls to add_preempt_count() (especially those from the selftests) will therefore not result in a call to trace_preempt_off() since the check below in add_preempt_count() will be false: if (preempt_count() == val) trace_preempt_off(CALLER_ADDR0, get_parent_ip(CALLER_ADDR1)); Hence the trace buffer will be empty.

This effectively implements a working runtime console in terms of the simple udbg primitives. This is kind of a hack - since udbg isn't something you really want to be using routinely - but it's really useful during bringup. This can be used to quickly implement a userspace-usable console while you're working on a proper driver for whatever console I/O device the hardware has. Or, it can be used to avoid writing a full blown tty/console driver entirely for quick-and-dirty I/O hardware that will later be replaced by something else.

We can make these same changes to __copy_tofrom_user() because the basic copy algorithm is the same as in memcpy() - this version just has all the exception handling logic needed when copying to or from userspace as well as a special case for copying whole 4K pages that are page aligned.

The problem is that the per-cpu tg->cfs_rq load weight used in the sd_rq_weight aggregation and actual redistribution of the cfs_rq->shares are collected at different time. Under moderate system load, we've seen quite a bit of variation on the cfs_rq->shares and ultimately wildly affects sched_entity's load weight. This patch caches the result of initial per-cpu load weight when doing the sum calculation, and then pass it down to update_group_shares_cpu() for redistributing per-cpu cfs_rq shares. This allows consistent total cfs_rq shares across all CPUs. It also simplifies the rounding and zero load weight check.

This patch involves some hackery to maintain compatablity between the new and old model, so all 300+ drivers don't have to be changed at once. For drivers that aren't converted yet, the netdevice_ops virt function list still resides in the net_device structure. For old protocols, the new net_device_ops are copied out to the old net_device pointers. After the transistion is completed the nag message can be changed to an WARN_ON, and the compatiablity code can be made configurable. Some function pointers aren't moved: * destructor can't be in net_device_ops because it may need to be referenced after the module is unloaded. * neighbor setup is manipulated in a couple of places that need special consideration * hard_start_xmit is in the fast path for transmit.

This is not suitable to look for a specific matching inside a set of nested attributes. For example, in ctnetlink messages, if we look for the CTA_V6_SRC attribute in a message that talks about an IPv4 connection, SKF_AD_NLATTR returns the offset of CTA_STATUS which has the same value of CTA_V6_SRC but outside the nest. To differenciate CTA_STATUS and CTA_V6_SRC, we would have to make assumptions on the size of the attribute and the usual offset, resulting in horrible BSF code. This patch adds SKF_AD_NLATTR_NEST, which is a variant of SKF_AD_NLATTR, that looks for an attribute inside the limits of a nested attributes, but not further. This patch validates that we have enough room to look for the nested attributes - based on a suggestion from Patrick McHardy.

The save_args function becomes really straightforward and easy to understand, with the possible exception of the stack switch code, which now needs to copy the return address of to the calling function. Normal interrupts arrive with ((~vector)-0x80) on the stack, which gets adjusted in common_interrupt: : (5) addq $0xffffffffffffff80,(%rsp) /* -> ~(vector) */ (4) sub $0x50,%rsp /* space for registers */ (5) callq ffffffff80211290 (5) callq ffffffff80214290 : ... An apic interrupt stub now look like this: : (5) pushq $0xffffffffffffff05 /* ~(vector) */ (4) sub $0x50,%rsp /* space for registers */ (5) callq ffffffff80211290 (5) callq ffffffff80212b8f (5) jmpq ffffffff80211f93 Similarly the exception handler register saving function becomes simpler, without the need of any parameter shuffling. The stub for an exception without errorcode looks like this: : (6) callq *0x1cad12(%rip) # ffffffff803dd448 (2) pushq $0xffffffffffffffff /* no syscall */ (4) sub $0x78,%rsp /* space for registers */ (5) callq ffffffff8030e3b0 (3) mov %rsp,%rdi /* pt_regs pointer */ (2) xor %esi,%esi /* no error code */ (5) callq ffffffff80213446 (5) jmpq ffffffff8030e460 And one for an exception with errorcode like this: : (6) callq *0x1cab92(%rip) # ffffffff803dd448 (4) sub $0x78,%rsp /* space for registers */ (5) callq ffffffff8030e3b0 (3) mov %rsp,%rdi /* pt_regs pointer */ (5) mov 0x78(%rsp),%rsi /* load error code */ (9) movq $0xffffffffffffffff,0x78(%rsp) /* no syscall */ (5) callq ffffffff80213209 (5) jmpq ffffffff8030e460 Unfortunately, this last type is more than 32 bytes. But the total space savings due to this patch is about 2500 bytes on an smp-configuration, and I think the code is clearer than it was before. The tested kernels were non-paravirt ones (i.e., without the indirect call at the top of the exception handlers). Anyhow, I tested this patch on top of a recent -tip. The machine was an 2x4-core Xeon at 2333MHz. Measured where the delays between (almost-)adjacent rdtsc instructions. The graphs show how much time is spent outside of the program as a function of the measured delay. The area under the graph represents the total time spent outside the program. Eight instances of the rdtsctest were started, each pinned to a single cpu. The histogams are added. For each kernel two measurements were done: one in mostly idle condition, the other while running "bonnie++ -f", bound to cpu 0. Each measurement took 40 minutes runtime. See the attached graphs for the results. The graphs overlap almost everywhere, but there are small differences.

Per-port registers are accessed in the following way: #define PORT_STATUS(p) (0x0444 + ((p) << 10)) [...] static inline u32 rdl(struct mv643xx_eth_private *mp, int offset) { return readl(mp->shared->base + offset); } [...] port_status = rdl(mp, PORT_STATUS(mp->port_num)); By giving the per-port 'struct mv643xx_eth_private' its own 'void __iomem *base' pointer that points to the per-port register area, we can get rid of both the double indirection and the << 10 that is done for every per-port register access -- this patch does that.

This patch switches mv643xx_eth over from ->set_multicast_list() to ->set_rx_mode(), and implements support for secondary unicast addresses. The hardware can handle multiple unicast addresses as long as their first 11 nibbles are the same (i.e. are of the form xx:xx:xx:xx:xx:xy where the x part is the same for all addresses), so if that is the case, we use that mode. If it's not the case, we enable unicast promiscuous mode in the hardware, which is slightly better than enabling promiscuous mode for multicasts as well, which is what would happen before. While we are at it, change the programming sequence so that we don't clear all filter bits first, so we don't lose all incoming packets while the filter is being reprogrammed.

The mic inputs are lost on such hardware by the change 5d5d5f43f1b835c375de9bd270cce030d16e2871. This patch adds back the old laptop-eapd model, and create a new model "samsung" for the new one specific to Samsung laptops with automatic mic selection feature.

The DCB feature support included are Priority Grouping (PG) - which allows bandwidth guarantees to be allocated to groups to traffic based on the 802.1q priority, and Priority Based Flow Control (PFC) - which introduces a new MAC control PAUSE frame which works at granularity of the 802.1p priority instead of the link (IEEE 802.3x).

These SFP+ PHY's are accessed via an I2C interface so the patch also includes functions to support this. Another feature of note is that the PHY is pluggable and some rearchitecting was needed to support this.

For example, machine wide data such as the struct snd_card are maintained as part of the CODEC data structure, preventing the use of multiple codecs. This has been addressed by refactoring the data structures so that all the data for the ALSA card is contained in a single structure snd_soc_card which replaces the existing snd_soc_machine and snd_soc_device. Begin the process of backporting this by renaming struct snd_soc_machine to struct snd_soc_card, better reflecting its function and bringing it closer to standard ALSA terminology.

Backport this change. This paves the way for future work allowing any combination of DAIs to be connected rather than having fixed purpose CODEC and CPU DAIs and only allowing CODEC<->CPU interconnections.

The board has two options for the MCLK of the WM9713: either the standard AC97 system clock can be used or the 13MHz CLK_POUT output of the PXA3xx can be used, selected via SW15 on the board. Currently only the AC97 system clock is supported by this driver.

Linville" Date: Fri, 31 Oct 2008 14:13:12 -0400 Subject: netdevice zd1201: Convert directly reference of netdev->priv to netdev_priv() We have some reasons to kill netdev->priv: 1. netdev->priv is equal to netdev_priv(). 2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously netdev_priv() is more flexible than netdev->priv. But we cann't kill netdev->priv, because so many drivers reference to it directly. OK, becasue Dave S. Miller said, "every direct netdev->priv usage is a bug", and I want to kill netdev->priv later, I decided to convert all the direct reference of netdev->priv first. (Original patch posted by Wang Chen w/ above changelog but using dev->ml_priv. That doesn't seem appropriate to me for this driver, so I've revamped it to use netdev_priv() instead. -- JWL) Reviewed-by: Wang Chen Signed-off-by: John W.

The device name is managed in the kobject anyway, and without any size limitation, and just needlessly copied into "struct device". To set and read the device name dev_name(dev) and dev_set_name(dev) must be used. If your code uses static kobjects, which it shouldn't do, "const char *init_name" can be used to statically provide the name the registered device should have. At registration time, the init_name field is cleared, to enforce the use of dev_name(dev) to access the device name at a later time. We need to get rid of all occurrences of bus_id in the entire tree to be able to enable the new interface. Please apply this patch, and possibly convert any remaining remaining occurrences of bus_id. We want to submit a patch to -next, which will remove bus_id from "struct device", to find the remaining pieces to convert, and finally switch over to the new api, which will remove the 20 bytes array and does no longer have a size limitation.

This makes sure that the LEDS will always be in a sane state after the state switch. Note that when unregister is called but the LED class wasn't resumed yet, we shouldn't change the LED state since we might not have access to the device (device was unplugged while suspended). Also remove the checks in the activity, assoc and radio LEDS which blocked calls to brightness_set() when the state hasn't changed. Some of those LEDS could be enabled by themselves when something happens in the hardware (e.g. firmware is loaded). We already did called rt2x00leds to switch the LED off, but those calls were blocked. Signed-off-by: Ivo van Doorn Signed-off-by: John W.

This fixes that by catching the value early in rt2x00config.c and replacing it with a sensible value. This also fixes a problem where the antenna is not being initialized at all when the radio is enabled. Since it no longer is part of the mac80211 configuration the only place where rt2x00 configured it was the SW diversity handler. Obviously this is broken for all non-diversity hardware and breaks SW diversity due to a broken initialization. When the radio is enabled the antenna will be configured once as soon as the config() callback function is called. Signed-off-by: Ivo van Doorn Signed-off-by: John W.

This must be protected under a lock to prevent race conditions which could cause invalid data to be returned when reading from the indirect register or silent failures when writing data to the indirect register. USB drivers where already protected under a mutex, so rename the mutex and make PCI drivers use the mutex as well. This now means that BBP and RF registers are no longer accessible in interrupt context. That is not a bad situation since the slow behavior of accessing those registers means we don't _want_ to access them in interrupt context either. Signed-off-by: Ivo van Doorn Signed-off-by: John W.

The WRITE index points +to the _next_ packet to be written and is advanced when after the TBD has been +filled. + +The firmware pulls from the TBD queue at the READ index. The READ index points +to the currently being read entry, and is advanced once the firmware is +done with a packet. + +When data is sent to the firmware, the first TBD is used to indicate to the +firmware if a Command or Data is being sent.

beb2a7f331361bfe81e71acdb0739eae570475a2 Mon Sep 17 00:00:00 2001 From: "John W. Linville" Date: Tue, 11 Nov 2008 16:45:38 -0500 Subject: net/ieee80211 -> drivers/net/ipw2x00/libipw_* rename The old ieee80211 code only remains as a support library for the ipw2100 and ipw2200 drivers. So, move the code and rename it appropriately to reflects it's true purpose and status. Signed-off-by: John W.

For ICH8/9, the valid NVM bank detect function was not checking whether the SEC1VAL (sector 1 valid) bit in the EECD register was itself valid (bits 8 and 9 also have to be set). If invalid, it would have defaulted to the possibly invalid bank 0. Instead, try to use the valid bank detection method used by ICH10 which has been cleaned up a bit. [1] - reads and updates only; not writes because those are only writing to the Shadow RAM, the update following the write is the only thing actually writing the modified Shadow RAM contents to the NVM.

Checkin 14d7ca5c575853664d8fe4f225a77b8df1b7de7d changed the default reboot method to "pci", a.k.a. port CF9. Unfortunately this has been shown to cause lockups on at least two systems for which REBOOT_KBD worked, both Thinkpads with Intel chipsets.

But it could be unsafe to store these return addresses to the stack. So these arrays will now be allocated dynamically into task_struct of current only when the tracer is activated. Typical scheme when tracer is activated: - allocate a return stack for each task in global list. - fork: allocate the return stack for the newly created task - exit: free return stack of current - idle init: same as fork I chose a default depth of 50. I don't have overruns anymore.

They should never change. But the compiler complains when they are passed into the debugfs_create_file as a data pointer, because the function discards the qualifier. This patch typecasts the parameter to debugfs_create_file back to a void pointer. To remind the callbacks that they are pointing to a constant value, I also modified the callback local pointers to be const struct ftrace_pointer * as well.

The only trick here is that a socket of a given type (TCP ipv4, TCP ipv6, ...) can now flight between two different tables (established and listening) during a RCU grace period, so we must use different 'nulls' end-of-chain values for two tables. We define a large value : #define LISTENING_NULLS_BASE (1U << 29) So that slots in listening table are guaranteed to have different end-of-chain values than slots in established table.

It is made against the 2008-11-23 snapshot. Added Realtek ALC888 model entry for the Fujitsu-Siemens Amilo Xa3530 laptop. It has 4 jacks: HP out, Mic-in, Line-in and Line-out/Side/SPDIF (this one is on the laptop side, the other ones are on the rear). Model detection works. Headphone jack sense works now. Front mic works now, was same as Acer Aspire 4930G. Added channel mode from 2 to 8 channels. In 2ch and 4ch modes, the front is also sent to the Line-out/side jack for convenience instead of just muting the Line-out/side jack like other models do. When using the Mic-in jack as CLFE, the sound is very low (bug?). To work it around, in 6ch mode the CLFE channel is duplicated to the Line-out/side jack because this one has a better amp.

David mentioned the HAVE_EFFICIENT_UNALIGNED_ACCESS test to handle this on all arches that have efficient unailgned accesses. I tried this idea and got nice assembly on 32 bits: 158: 33 82 38 01 00 00 xor 0x138(%edx),%eax 15e: 33 8a 34 01 00 00 xor 0x134(%edx),%ecx 164: c1 e0 10 shl $0x10,%eax 167: 09 c1 or %eax,%ecx 169: 74 0b je 176 And very nice assembly on 64 bits of course (one xor, one shl) Nice oprofile improvement in eth_type_trans(), 0.17 % instead of 0.41 %, expected since we remove 8 instructions on a fast path. This patch implements a compare_ether_addr_64bits() function, that uses the CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS ifdef to efficiently perform the 6 bytes comparison on all capable arches.

Unfortunately this has been shown to cause lockups on at least two systems for which REBOOT_KBD worked, both Thinkpads with Intel chipsets. Checkin 3889d0cea2b73049bdca062d9ff1e5d33468289c reverted the default, but did not revert the fallback chain.

This pressure is visible on RTP servers when delivering content to mediagateways, especially big ones, handling thousand of streams. Several cpus send UDP frames to the same destination, hence use the same dst entry. This patch makes ip_append_data() eventually steal the refcount its callers had to take on the dst entry.

Corresponding ecryptfs fixes (by David Howells) are here as well. Fix refcounting. The following rules now apply: 1. The task pins the user struct. 2. The user struct pins its user namespace. 3. The user namespace pins the struct user which created it. User namespaces are cloned during copy_creds(). Unsharing a new user_ns is no longer possible. (We could re-add that, but it'll cause code duplication and doesn't seem useful if PAM doesn't need to clone user namespaces). When a user namespace is created, its first user (uid 0) gets empty keyrings and a clean group_info. This incorporates a previous patch by David Howells. Here is his original patch description: >I suggest adding the attached incremental patch. It makes the following >changes: > > (1) Provides a current_user_ns() macro to wrap accesses to current's user > namespace. > > (2) Fixes eCryptFS. > > (3) Renames create_new_userns() to create_user_ns() to be more consistent > with the other associated functions and because the 'new' in the name is > superfluous. > > (4) Moves the argument and permission checks made for CLONE_NEWUSER to the > beginning of do_fork() so that they're done prior to making any attempts > at allocation. > > (5) Calls create_user_ns() after prepare_creds(), and gives it the new creds > to fill in rather than have it return the new root user.

This pressure is visible on RTP servers when delivering content to mediagateways, especially big ones, handling thousand of streams. Several cpus send UDP frames to the same destination, hence use the same dst entry. This patch makes ip_push_pending_frames() steal the refcount its callers had to take when filling inet->cork.dst.

Then we're in problems when cleanup work for them has to be done when a large cumulative ACK comes. Try to return back to pre-split state already while more and more SACK info gets discovered by combining newly discovered SACK areas with the previous skb if that's SACKed as well. This approach has a number of benefits: 1) The processing overhead is spread more equally over the RTT 2) Write queue has less skbs to process (affect everything which has to walk in the queue past the sacked areas) 3) Write queue is consistent whole the time, so no other parts of TCP has to be aware of this (this was not the case with some other approach that was, well, quite intrusive all around). 4) Clean_rtx_queue can release most of the pages using single put_page instead of previous PAGE_SIZE/mss+1 calls In case a hole is fully filled by the new SACK block, we attempt to combine the next skb too which allows construction of skbs that are even larger than what tso split them to and it handles hole per on every nth patterns that often occur during slow start overshoot pretty nicely. Though this to be really useful also a retransmission would have to get lost since cumulative ACKs advance one hole at a time in the most typical case. TODO: handle upwards only merging. That should be rather easy when segment is fully sacked but I'm leaving that as future work item (it won't make very large difference anyway since this current approach already covers quite a lot of normal cases). I was earlier thinking of some sophisticated way of tracking timestamps of the first and the last segment but later on realized that it won't be that necessary at all to store the timestamp of the last segment. The cases that can occur are basically either: 1) ambiguous => no sensible measurement can be taken anyway 2) non-ambiguous is due to reordering => having the timestamp of the last segment there is just skewing things more off than does some good since the ack got triggered by one of the holes (besides some substle issues that would make determining right hole/skb even harder problem). Anyway, it has nothing to do with this change then. I choose to route some abnormal looking cases with goto noop, some could be handled differently (eg., by stopping the walking at that skb but again). In general, they either shouldn't happen at all or are rare enough to make no difference in practice. In theory this change (as whole) could cause some macroscale regression (global) because of cache misses that are taken over the round-trip time but it gets very likely better because of much less (local) cache misses per other write queue walkers and the big recovery clearing cumulative ack. Worth to note that these benefits would be very easy to get also without TSO/GSO being on as long as the data is in pages so that we can merge them. Currently I won't let that happen because DSACK splitting at fragment that would mess up pcounts due to sk_can_gso in tcp_set_skb_tso_segs. Once DSACKs fragments gets avoided, we have some conditions that can be made less strict. TODO: I will probably have to convert the excessive pointer passing to struct sacktag_state... :-) My testing revealed that considerable amount of skbs couldn't be shifted because they were cloned (most likely still awaiting tx reclaim)... [The rest is considering future work instead since I got repeatably EFAULT to tcpdump's recvfrom when I added pskb_expand_head to deal with clones, so I separated that into another, later patch] ...To counter that, I gave up on the fifth advantage: 5) When growing previous SACK block, less allocs for new skbs are done, basically a new alloc is needed only when new hole is detected and when the previous skb runs out of frags space ...which now only happens of if reclaim is fast enough to dispose the clone before the SACK block comes in (the window is RTT long), otherwise we'll have to alloc some.

With rt2800usb on its way, we should favor the 32bit register access and move those wrappers into rt2x00usb. That saves duplicate code, since only rt2500usb will need the special 16bit wrappers.

This means that if that function fails the queue must be stopped in mac80211. When rt2x00queue_get_queue() returns NULL in the TX path, it means mac80211 has passed us an invalid queue, although this should be impossible, it shouldn't hurt if we send mac80211 a signal to stop the queue either. Both issues can simply be resolved by removing their manual failure handler and making them use the failure path provided in rt2x00mac_tx(). Signed-off-by: Ivo van Doorn Signed-off-by: John W.

We now can support 5 mac80211 filter flags: FIF_OTHER_BSS, FIF_ALLMULTI, FIF_PROMISC_IN_BSS, FIF_BCN_PRBRESP_PROMISC and FIF_CONTROL. This patch also avoids reconnecting if the filter flags are changed when the STA is associated. Because rx_assoc is used when full rxon is not necessary.

So remove the informative complaint about it assuming it will tell us such things. Note that you can determine if CRDA is present after loading cfg80211 by using: is_old_static_regdom(cfg80211_regdomain) but this doesn't account for possible user install after initial boot, and also for when the user uses the static EU regulatory domain.

We parse the country IEs only on management beacons for the BSSID you are associated to and disregard the IEs when the country and environment (indoor, outdoor, any) matches the already processed country IE. To avoid following misinformed or outdated APs we build and use a regulatory domain out of the intersection between what the AP provides us on the country IE and what CRDA is aware is allowed on the same country. A secondary device is allowed to follow only the same country IE as it make no sense for two devices on a system to be in two different countries. In the case the AP is using country IEs for an incorrect country the user may help compliance further by setting the regulatory domain before or after the IE is parsed and in that case another intersection will be performed. CONFIG_WIRELESS_OLD_REGULATORY is supported but requires CRDA present. Signed-off-by: Luis R. Rodriguez Acked-by: Johannes Berg Signed-off-by: John W.

For this aim, we now call two handler for each function: one on the entry and one other on return. This way we can draw a well-ordered call stack. The pid of the previous trace is loosely stored to be compared against the one of the current trace to see if there were a context switch. Without this little feature, the call tree would seem broken at some locations. We could use the sched_tracer to capture these sched_events but this way of processing is much more simpler. 2 spaces have been chosen for indentation to fit the screen while deep calls. The time of execution in nanosecs is printed just after closed braces, it seems more easy this way to find the corresponding function. If the time was printed as a first column, it would be not so easy to find the corresponding function if it is called on a deep depth. I plan to output the return value but on 32 bits CPU, the return value can be 32 or 64, and its difficult to guess on which case we are. I don't know what would be the better solution on X86-32: only print eax (low-part) or even edx (high-part). Actually it's thee same problem when a function return a 8 bits value, the high part of eax could contain junk values... Here is an example of trace: sys_read() { fget_light() { } 526 vfs_read() { rw_verify_area() { security_file_permission() { cap_file_permission() { } 519 } 1564 } 2640 do_sync_read() { pipe_read() { __might_sleep() { } 511 pipe_wait() { prepare_to_wait() { } 760 deactivate_task() { dequeue_task() { dequeue_task_fair() { dequeue_entity() { update_curr() { update_min_vruntime() { } 504 } 1587 clear_buddies() { } 512 add_cfs_task_weight() { } 519 update_min_vruntime() { } 511 } 5602 dequeue_entity() { update_curr() { update_min_vruntime() { } 496 } 1631 clear_buddies() { } 496 update_min_vruntime() { } 527 } 4580 hrtick_update() { hrtick_start_fair() { } 488 } 1489 } 13700 } 14949 } 16016 msecs_to_jiffies() { } 496 put_prev_task_fair() { } 504 pick_next_task_fair() { } 489 pick_next_task_rt() { } 496 pick_next_task_fair() { } 489 pick_next_task_idle() { } 489 ------------8<---------- thread 4 ------------8<---------- finish_task_switch() { } 1203 do_softirq() { __do_softirq() { __local_bh_disable() { } 669 rcu_process_callbacks() { __rcu_process_callbacks() { cpu_quiet() { rcu_start_batch() { } 503 } 1647 } 3128 __rcu_process_callbacks() { } 542 } 5362 _local_bh_enable() { } 587 } 8880 } 9986 kthread_should_stop() { } 669 deactivate_task() { dequeue_task() { dequeue_task_fair() { dequeue_entity() { update_curr() { calc_delta_mine() { } 511 update_min_vruntime() { } 511 } 2813 Signed-off-by: Frederic Weisbecker Acked-by: Steven Rostedt Signed-off-by: Ingo Molnar diff --git a/arch/x86/kernel/ftrace.c b/arch/x86/kernel/ftrace.c index 3595a4c..26b2d92 100644 --- a/arch/x86/kernel/ftrace.c +++ b/arch/x86/kernel/ftrace.c @@ -347,7 +347,7 @@ void ftrace_nmi_exit(void) /* Add a function return address to the trace stack on thread info.*/ static int push_return_trace(unsigned long ret, unsigned long long time, - unsigned long func) + unsigned long func, int *depth) { int index;

Since IRQSAFE mode is removed, we have to change the pcsp start-up code. This patch splits the callback function to two parts, the triggering of the port and the calculation of the expire time, and the update of the ALSA PCM core. The first part is called both from the trigger-start and the hrtimer callback while the latter is handled only in the hrtimer callback.

This means there is potentially a hidden call in the resume code flow that changes rfkill->state (i.e. rfkill_force_state()), so the previous state of the transmitter was being lost. The simplest and most future-proof way to fix this is to explicitly store the pre-sleep state on the rfkill structure, and restore from that on resume.

This patch reorders entry_64.S and explicitly generates a separate section for functions that need the protection. The generated code before and after the patch is equal. Implicitly changing sections in assembly files makes it more difficult to follow why the assembler is doing certain things. For example, .p2align 5 KPROBE_ENTRY(...) was not doing what you would expect. Other section changes (__ex_table, .fixup, .init.rodata) are done explicitly already.

The mcount locations are now found at compile time. The mcount function no longer needs to store registers and call a stub function. It can now just simply return. Since there are some functions that do not get converted to a nop (.init sections and other code that may disappear), this patch should help speed up that code. Also, the stub for mcount on PowerPC 32 can not be a simple branch link register like it is on PowerPC 64. According to the ABI specification: "The _mcount routine is required to restore the link register from the stack so that the profiling code can be inserted transparently, whether or not the profiled function saves the link register itself." This means that we must restore the link register that was used to make the call to mcount. The minimal mcount function for PPC32 ends up being: mcount: mflr r0 mtctr r0 lwz r0, 4(r1) mtlr r0 bctr Where we move the link register used to call mcount into the ctr register, and then restore the link register from the stack. Then we use the ctr register to jump back to the mcount caller. The r0 register is free for us to use.

The Bluetooth 1.0b specification was ambiguous on how the device firmware was suppose to handle it. Almost every device was triggering a transport reset at the same time. In case of USB this ended up in disconnects from the bus. All modern Bluetooth dongles handle this perfectly fine and a lot of them actually require that HCI Reset is sent. If not then they are either stuck in their HID Proxy mode or their internal structures for inquiry and paging are not correctly setup. To handle old and new devices smoothly the Bluetooth subsystem contains a quirk to force the HCI Reset on initialization. However maintaining such a quirk becomes more and more complicated. This patch turns the logic around and lets the old devices disable the HCI Reset command. The only device where the HCI_QUIRK_NO_RESET is still needed are the original Digianswer devices and dongles with an early CSR firmware. CSR reported that they fixed this for version 12 firmware. The last official release of version 11 firmware is build ID 115. The first version 12 candidate was build ID 117.

Create a new RFCOMM device (using RFCOMMCREATEDEV ioctl) 2. (Try to) open the device 3. Release the RFCOMM device (using RFCOMMRELEASEDEV ioctl) At this point, the "/dev/rfcomm*" device is still in use, but it is gone from the internal list, so the device id can be reused. 4. Create a new RFCOMM device with the same device id as before And now kobject will complain that the TTY already exists. (See http://lkml.org/lkml/2008/7/13/89 for a reproducible test-case.) This patch attempts to correct this by only removing the device from the internal list of devices at the final unregister stage, so that the id won't get reused until the device has been completely destructed. This should be safe as the RFCOMM_TTY_RELEASED bit will be set for the device and prevent the device from being reopened after it has been released.

To this purpose, handlers are used and added to the dccp_feat_table. Each handler is passed a boolean flag whether the RX or TX side of the feature is meant. Several handlers are provided already, new handlers can easily be added. The initialisation is now fully dynamic, i.e. CCIDs are activated only after the feature negotiation. The integration of this dynamic activation is done in the subsequent patches. Thanks to Wei Yongjun for pointing out the necessity of skipping over empty Confirm options while copying the negotiated feature values.

Both static and dynamic tracing are supported. This causes some small CPP conditional asm on arch/x86/kernel/ftrace.c I wanted to use probe_kernel_read/write to make the return address saving/patching code more generic but it causes tracing recursion. That would be perhaps useful to implement a notrace version of these function for other archs ports. Note that arch/x86/process_64.c is not traced, as in X86-32. I first thought __switch_to() was responsible of crashes during tracing because I believed current task were changed inside but that's actually not the case (actually yes, but not the "current" pointer). So I will have to investigate to find the functions that harm here, to enable tracing of the other functions inside (but there is no issue at this time, while process_64.c stays out of -pg flags). A little possible race condition is fixed inside this patch too. When the tracer allocate a return stack dynamically, the current depth is not initialized before but after. An interrupt could occur at this time and, after seeing that the return stack is allocated, the tracer could try to trace it with a random uninitialized depth. It's a prevention, even if I hadn't problems with it.

But it can happen that an unmap operation unmaps memory which is behind the current next_bit location. If these addresses are reused it may result in stale GART IO/TLB entries. Fix this by setting the GART next_bit always behind an unmapped location.

Well, it was hard for me to find out that was happening because the bug would not print, it would just cause a hard lockup or reboot. The reason is that it is not safe to call printk from this function. Looking further, I also found that it calls unregister_ftrace_graph, which grabs a mutex and calls kstop machine. This would definitely lock the box up if it were to trigger. This patch adds a fast and safe ftrace_graph_stop() which will stop the function tracer. Then it is safe to call the WARN ON.

But we lose out where the actually function was called from. This patch adds in hooks to the dumpstack mechanism that detects this and finds the real function to print. Both are printed to let the user know that a hook is still in place.

If PPC_NEED_DMA_SYNC_OPS is not defined, the dma_sync_*_for_* ops compile to nothing. Otherwise, they access the dma_ops pointers for the sync ops.

Previously, the BSR driver only supported a single OF node describing a BSR. Apparently when an LPAR is set to use "all system resources" the BSR appears as a single node, but when it is handed out in pieces, each 8 byte piece gets its own node. So, this keeps a list of BSR devices instead of the array and includes all nodes. Also, this makes the code be more inclusive of what BSR devices we accept by only checking compatibility and not the device name property (which might change in the future versions of BSR).

This patch adds input source controls. It modifies default register values to have no inputs selected and ADCs disabled. When some input is selected, control handlers enable apropriate input amplifier and ADC. If a microphone is selected, bias power is automatically enabled. When some input is deselected, unused chip parts are disabled. Microphone and line input recording tested on OMAP3 pandora board.

This patch add the handlers of SPE/EFP exceptions. The code is used to emulate float point arithmetic, when MSR(SPE) is enabled and receive EFP data interrupt or EFP round interrupt. This patch has no conflict with or dependence on FP math-emu. The code has been tested by TestFloat. Now the code doesn't support SPE/EFP instructions emulation (it won't be called when receive program interrupt), but it could be easily added.

If this code supported booting a secondary processor, which it doesn't yet, but if it did, then when a secondary processor boots, it would probably signal the primary processor by setting a variable called something like __secondary_hold_acknowledge. However, due to the lack of the M bit, the primary processor would not snoop the transaction (even if a transaction were broadcast). If primary CPU's L1 D-cache had a copy, it would not be flushed and the CPU would never see the ack. Which would have resulted in the primary CPU spinning for a long time, perhaps a full second before it gives up, while it would have waited for the ack from the secondary CPU that it wouldn't have been able to see because of the stale cache. The value of MAS2 for the boot page TLB1 entry is a compile time constant, so there is no need to calculate it in powerpc assembly language. Also, from the MPC8572 manual section 6.12.5.3, "Bits that represent offsets within a page are ignored and should be cleared." Existing code didn't clear them, this code does. The same when the page of KERNELBASE is found; we don't need to use asm to mask the lower 12 bits off. In the code that computes the address to rfi from, don't hard code the offset to 24 bytes, but have the assembler figure that out for us.

Although Linux has been supporting HD-audio since long +time ago, there are often problems with new machines. A part of the +problem is broken BIOS, and rest is the driver implementation. This +document explains the trouble-shooting and debugging methods for the +HD-audio hardware. + +The HD-audio component consists of two parts: the controller chip and +the codec chips on the HD-audio bus. Linux provides a single driver +for all controllers, snd-hda-intel. Since the HD-audio controllers +are supposed to be compatible, the single snd-hda-driver should work +in most cases. But, not surprisingly, there are known bugs and issues +specific to each controller type. The snd-hda-intel driver has a +bunch of workarounds for these as described below. + +A controller may have multiple codecs. Usually you have one audio +codec and optionally one modem codec. In some cases, there can be +multiple audio codecs, e.g. for analog and digital outputs, but the +driver might not work properly. + +The snd-hda-intel driver has several different codec parsers depending +on the codec. It has a generic parser as a fallback, but this +functionality is fairly limited until now. Instead of the generic +parser, usually the codec-specific parser (coded in patch_*.c) is used +for the codec-specific implementations. The details about the +codec-specific problems are explained in the later sections. + +If you are interested in the deep debugging of HD-audio, read the +HD-audio specification at first. The specification is found on +Intel's web page, for example: + +- http://www.intel.com/standards/hdaudio/ + + +HD-AUDIO CONTROLLER +------------------- + +DMA-Position Problem +~~~~~~~~~~~~~~~~~~~~ +The most common problem of the controller is the inaccurate DMA +pointer reporting. The DMA pointer for playback and capture can be +read in two ways, either via a LPIB register or via a position-buffer +map. As default the driver tries to reads from the io-mapped +position-buffer, and falls back to LPIB if it appears unupdated. +However, this detection isn't perfect on some devices. In such a +case, you can change the default method via `position_fix` option. + +`position_fix=1` means to use LPIB method explicitly. +`position_fix=2` means to use the position-buffer. 0 is the default +value, the automatic check. If you get a problem of repeated sounds, +this option might help. + +In addition to that, every controller is known to be broken regarding +the wake-up timing. It wakes up a few samples before actually +processing the data on the buffer. This caused a lot of problems, for +example, with ALSA dmix or JACK. Since 2.6.27 kernel, the driver puts +an artificial delay to the wake up timing. This delay is controlled +via `bdl_pos_adj` option. + +When `bdl_pos_adj` is a negative value (as default), it's assigned to +an appropriate value depending on the controller chip. For Intel +chip, it'd be 1 while it'd be 32 for others. Usually this works. +Only in case it doesn't work and you get warning messages, you should +change to other values. + + +Codec-Probing Problem +~~~~~~~~~~~~~~~~~~~~~ +A less often but a more severe problem is the codec probing. When +BIOS reports the available codec slots wrongly, the driver gets +confused and tries to access the non-existing codec slot. This often +results in the total screw-up, and destruct the further communication +with the codec chips. The symptom appears usually as the error +message like: +------------------------------------------------------------------------ + hda_intel: azx_get_response timeout, switching to polling mode: \ + last cmd=0x12345678 + hda_intel: azx_get_response timeout, switching to single_cmd mode: \ + last cmd=0x12345678 +------------------------------------------------------------------------ + +The first line is a warning, and this is usually relatively harmless. +It means that the codec response isn't notified via an IRQ. The +driver uses explicit polling method to read the response. It gives +very slight CPU overhead, but you'd unlikely notice it. + +The second line is, however, a fatal error. If this happens, usually +it means that something is really wrong. Most likely you are +accessing a non-existing codec slot. + +Thus, if the second error message appears, try to narrow the probed +codec slots via `probe_mask` option. It's a bitmask, and each bit +corresponding to the codec slot. For example, to probe only the +first slot, pass `probe_mask=1`. For the first and the third slots, +pass `probe_mask=5` (where 5 = 1 | 4), and so on. + +Since 2.6.29 kernel, the driver has a more robust probing method, so +this error might happen rarely, though. + + +Interrupt Handling +~~~~~~~~~~~~~~~~~~ +In rare but some cases, the interrupt isn't properly handled as +default. You would notice this by the DMA transfer error reported by +ALSA PCM core, for example. Using MSI might help in such a case. +Pass `enable_msi=1` option for enabling MSI. + + +HD-AUDIO CODEC +-------------- + +Model Option +~~~~~~~~~~~~ +The most common problems with the HD-audio driver is the unsupported +codec features or the mismatched device configuration. Most of +codec-specific code has several preset models, either to override the +BIOS setup or to provide more comprehensive features. + +The driver checks PCI SSID and looks through the static configuration +table until any matching entry is found. If you have a new machine, +you may see a message like below: +------------------------------------------------------------------------ + hda_codec: Unknown model for ALC880, trying auto-probe from BIOS... +------------------------------------------------------------------------ +Even if you such a message, DON'T PANIC. Take a deep breath (and keep +your towel). First of all, it's an informational message, no warning, +no error. This means that the PCI SSID of your device isn't listed in +the known preset model list. But, this doesn't mean that the driver +is broken. Many codec-driver provides the automatic configuration +based on the BIOS setup. + +The HD-audio codec has usually "pin" widgets, and BIOS sets the default +configuration of each pin, which indicates the location, the +connection type, the jack color, etc. The HD-audio driver can guess +the right connection judging from these default configuration values. +However -- some codec support codes, such as patch_analog.c, don't +support the automatic probing (yet as of 2.6.28). And, BIOS is often, +yes, pretty often broken. It sets up wrong values and screws up the +driver. + +The preset model is provided basically to override such a situation. +When the matching preset model is found in the list, the driver +assumes the static configuration of that preset and builds the mixer +and PCM based on the static information. Thus, if you have a newer +machine with a slightly different PCI SSID from the existing one, you +may have a good chance to re-use the same model. You can pass the +`model` option to specify the preset model instead of PCI SSID +look-up. + +What `model` option values are available depends on the codec chip. +Check your codec chip from the codec proc file (see "Codec Proc-File" +section below). It will show the vendor/product name of your codec +chip. Then, see Documentation/sound/alsa/ALSA-Configuration.txt file. +In the section of HD-audio driver, you can find a list of codecs and +`model` options belonging to each codec. For example, for Realtek +ALC262 codec chip, pass `model=ultra` for devices that are compatible +with Samsung Q1 Ultra. + +Thus, the first thing you can do for any brand-new, unsupported +HD-audio hardware is to check HD-audio codec and several different +`model` option values. If you have a luck, some of them might suit +with your device well. + +Some codecs such as ALC880 have a special model option `model=test`. +This configures the driver to provide as many mixer controls as +possible for every single pin feature except for the unsolicited +events (and maybe some other specials). Adjust each mixer element and +try the I/O in the way of trial-and-error until figuring out the whole +I/O pin mappings. + +Note that `model=generic` has a special meaning. It means to use the +generic parser regardless of the codec. Usually the codec-specific +parser is much better than the generic parser (as now). Thus this +option is more about the debugging purpose. + + +Speaker and Headphone Output +~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +One of the most frequent (and obvious) bugs with HD-audio is the +silent output from either or both of a built-in speaker and a +headphone jack. In general, you should try a headphone output at +first. A speaker output often requires more additional controls like +the amplifier. Thus a headphone output has a slightly better chance. + +Before making a bug report, double-check whether the mixer is set up +correctly. The recent version of snd-hda-intel driver provides mostly +"Master" volume control as well as "Front" volume. In addition, there +are individual "Headphone" and "Speaker" controls. + +Ditto for the speaker output. There can be "External Amplifier" +switch on some codecs. Turn on this if present. + +Another related problem is the automatic mute of speaker output by +headphone plugging. This feature is implemented in most cases, but +not on every preset model or codec-support code. + +In anyway, try a different model option if you have such a problem. +Some other models may match better and give you more matching +functionality. If none of the available models works, send a bug +report. See the bug report section for details. + +If you are masochistic enough to debug the driver problem, note the +following: + +- The speaker (and the headphone, too) output often requires the + external amplifier. This can be set usually via EAPD verb or a + certain GPIO. If the codec pin supports EAPD, you have a better + chance via SET_EAPD_BTL verb (0x70c). On others, GPIO pin (mostly + it's either GPIO0 or GPIO1) can turn on/off EAPD. +- Some Realtek codecs require special vendor-specific coefficients to + turn on the amplifier. See patch_realtek.c. +- IDT codecs may have extra power-enable/disable controls on each + analog pin. See patch_sigmatel.c. +- Very rare but some devices don't accept the pin-detection verb until + triggered. Issuing GET_PIN_SENSE verb (0xf09) may result in the + codec-communication stall. Some examples are found in + patch_realtek.c. + + +Capture Problems +~~~~~~~~~~~~~~~~ +The capture problems are often missing setups of mixers. Thus, before +submitting a bug report, make sure that you set up the mixer +correctly. For example, both "Capture Volume" and "Capture Switch" +have to be set properly in addition to the right "Capture Source" or +"Input Source" selection. Some devices have "Mic Boost" volume or +switch. + +When the PCM device is opened via "default" PCM (without pulse-audio +plugin), you'll likely have "Digital Capture Volume" control as well. +This is provided for the extra gain/attenuation of the signal in +software, especially for the inputs without the hardware volume +control such as digital microphones. Unless really needed, this +should be set to exactly 50%, corresponding to 0dB. When you use "hw" +PCM, i.e., a raw access PCM, this control will have no influence, +though. + +It's known that some codecs / devices have fairly bad analog circuits, +and the recorded sound contains a certain DC-offset. This is no bug +of the driver. + +Most of modern laptops have no analog CD-input connection. Thus, the +recording from CD input won't work in many cases although the driver +provides it as the capture source. + +The automatic switching of the built-in and external mic per plugging +is implemented on some codec models but not on every model. Partly +because of my laziness but mostly lack of testers. Feel free to +submit the improvement patch to the author. + + +Direct Debugging +~~~~~~~~~~~~~~~~ +If no model option gives you a better result, and you are a touch guy +to fight again the evil, try debugging via hitting the raw HD-audio +codec verbs to the device. Some tools are available: hda-emu and +hda-analyzer. The detailed description is found in the sections +below. You'd need to enable hwdep for using these tools. See "Kernel +Configuration". + + +OTHER ISSUES +------------ + +Kernel Configuration +~~~~~~~~~~~~~~~~~~~~ +In general, I recommend you to enable the sound debug option, +`CONFIG_SND_DEBUG=y`, no matter whether you are debugging or not. +This enables snd_printd() macro and others, and you'll get additional +kernel messages at probing. + +In addition, you can enable `CONFIG_SND_DEBUG_VERBOSE=y`. But this +will give you far more messages. Thus turn this on only when you are +sure to want it. + +Don't forget to turn on the appropriate `CONFIG_SND_HDA_CODEC_*` +options. Note that each of them corresponds to the codec chip, not +the controller chip. Thus, even if lspci shows the Nvidia controller, +you may choose the option for other vendors. If you are unsure, just +choose all yes. + +`CONFIG_SND_HDA_HWDEP` is a useful option for debugging the driver. +When this is enabled, the driver creates hardware-dependent devices +(one per each codec), and you have a raw access to the device via +hda-verb program. For example, `hwC0D2` will be created for the card +0 codec slot #2. For debug tools such as hda-verb and hda-analyzer, +the hwdep device has to be enabled. Thus, turn this on always. + +`CONFIG_SND_HDA_RECONFIG` is a new option, and this depends on the +hwdep option above. When enabled, you'll have some sysfs files under +the corresponding hwdep directory. See "HD-audio reconfiguration" +section below. + +`CONFIG_SND_HDA_POWER_SAVE` option enables the power-saving feature. +See "Power-saving" section below. + + +Codec Proc-File +~~~~~~~~~~~~~~~ +The codec proc-file is a treasure-chest for debugging HD-audio. +It shows most of useful information of each codec widget. + +The proc file is located in /proc/asound/card*/codec#*, one file per +each codec slot. You can know the codec vendor, product id and +names, the type of each widget, capabilities and so on. +This file, however, doesn't show the jack sensing state, so far. This +is because the jack-sensing might be depending on the trigger state. + +This file will be picked up by the debug tools, and also it can be fed +to the emulator as the primary codec information. See the debug tools +section below. + +This proc file can be also used to check whether the generic parser is +used. When the generic parser is used, the vendor/product ID name +will appear as "Realtek ID 0262", instead of "Realtek ALC262". + + +HD-Audio Reconfiguration +~~~~~~~~~~~~~~~~~~~~~~~~ +This is an experimental feature to allow you re-configure the HD-audio +codec dynamically without reloading the driver. The following sysfs +files are available under each codec-hwdep device directory (e.g. +/sys/class/sound/hwC0D0): + +vendor_id:: + Shows the 32bit codec vendor-id hex number. You can change the + vendor-id value by writing to this file. +subsystem_id:: + Shows the 32bit codec subsystem-id hex number. You can change the + subsystem-id value by writing to this file. +revision_id:: + Shows the 32bit codec revision-id hex number. You can change the + revision-id value by writing to this file. +afg:: + Shows the AFG ID. This is read-only. +mfg:: + Shows the MFG ID. This is read-only. +name:: + Shows the codec name string. Can be changed by writing to this + file. +modelname:: + Shows the currently set `model` option. Can be changed by writing + to this file. +init_verbs:: + The extra verbs to execute at initialization. You can add a verb by + writing to this file. Pass tree numbers, nid, verb and parameter. +hints:: + Shows hint strings for codec parsers for any use. Right now it's + not used. +reconfig:: + Triggers the codec re-configuration. When any value is written to + this file, the driver re-initialize and parses the codec tree + again. All the changes done by the sysfs entries above are taken + into account. +clear:: + Resets the codec, removes the mixer elements and PCM stuff of the + specified codec, and clear all init verbs and hints. + + +Power-Saving +~~~~~~~~~~~~ +The power-saving is a kind of auto-suspend of the device. When the +device is inactive for a certain time, the device is automatically +turned off to save the power. The time to go down is specified via +`power_save` module option, and this option can be changed dynamically +via sysfs. + +The power-saving won't work when the analog loopback is enabled on +some codecs. Make sure that you mute all unneeded signal routes when +you want the power-saving. + +The power-saving feature might cause audible click noises at each +power-down/up depending on the device. Some of them might be +solvable, but some are hard, I'm afraid. Some distros such as +openSUSE enables the power-saving feature automatically when the power +cable is unplugged. Thus, if you hear noises, suspect first the +power-saving. See /sys/modules/snd_hda_intel/parameters/power_save to +check the current value. If it's non-zero, the feature is turned on. + + +Sending a Bug Report +~~~~~~~~~~~~~~~~~~~~ +If any model or module options don't work for your device, it's time +to send a bug report to the developers. Give the following in your +bug report: + +- Hardware vendor, product and model names +- Kernel version (and ALSA-driver version if you built externally) +- `alsa-info.sh` output; run with `--no-upload` option. See the + section below about alsa-info + +If it's a regression, at best, send alsa-info outputs of both working +and non-working kernels. This is really helpful because we can +compare the codec registers directly. + +Send a bug report either the followings: + +kernel-bugzilla:: + http://bugme.linux-foundation.org/ +alsa-devel ML:: + alsa-devel@alsa-project.org + + +DEBUG TOOLS +----------- + +This section describes some tools available for debugging HD-audio +problems. + +alsa-info +~~~~~~~~~ +The script `alsa-info.sh` is a very useful tool to gather the audio +device information. You can fetch the latest version from: + +- http://www.alsa-project.org/alsa-info.sh + +Run this script as root, and it will gather the important information +such as the module lists, module parameters, proc file contents +including the codec proc files, mixer outputs and the control +elements. As default, it will store the information onto a web server +on alsa-project.org. But, if you send a bug report, it'd be better to +run with `--no-upload` option, and attach the generated file. + +There are some other useful options. See `--help` option output for +details. + + +hda-verb +~~~~~~~~ +hda-verb is a tiny program that allows you to access the HD-audio +codec directly. It executes a HD-audio codec verb directly. +This program accesses the hwdep device, thus you need to enable the +kernel config `CONFIG_SND_HDA_HWDEP=y` beforehand. + +The hda-verb program takes four arguments: the hwdep device file, the +widget NID, the verb and the parameter. When you access to the codec +on the slot 2 of the card 0, pass /dev/snd/hwC0D2 to the first +argument, typically. (However, the real path name depends on the +system.) + +The second parameter is the widget number-id to access. The third +parameter can be either a hex/digit number or a string corresponding +to a verb. Similarly, the last parameter is the value to write, or +can be a string for the parameter type. + +------------------------------------------------------------------------ + % hda-verb /dev/snd/hwC0D0 0x12 0x701 2 + nid = 0x12, verb = 0x701, param = 0x2 + value = 0x0 + + % hda-verb /dev/snd/hwC0D0 0x0 PARAMETERS VENDOR_ID + nid = 0x0, verb = 0xf00, param = 0x0 + value = 0x10ec0262 + + % hda-verb /dev/snd/hwC0D0 2 set_a 0xb080 + nid = 0x2, verb = 0x300, param = 0xb080 + value = 0x0 +------------------------------------------------------------------------ + +Although you can issue any verbs with this program, the driver state +won't be always updated. For example, the volume values are usually +cached in the driver, and thus changing the widget amp value directly +via hda-verb won't change the mixer value. + +The hda-verb program is found in the ftp directory: + +- ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/misc/ + +Also a git repository is available: + +- git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/hda-verb.git + +See README file in the tarball for more details about hda-verb +program. + + +hda-analyzer +~~~~~~~~~~~~ +hda-analyzer provides a graphical interface to access the raw HD-audio +control, based on pyGTK2 binding. It's a more powerful version of +hda-verb. The program gives you a easy-to-use GUI stuff for showing +the widget information and adjusting the amp values, as well as the +proc-compatible output. + +The hda-analyzer is a part of alsa.git repository in +alsa-project.org: + +- http://git.alsa-project.org/?p=alsa.git;a=tree;f=hda-analyzer + + +hda-emu +~~~~~~~ +hda-emu is a HD-audio emulator. The main purpose of this program is +to debug an HD-audio codec without the real hardware. Thus, it +doesn't emulate the behavior with the real audio I/O, but it just +dumps the codec register changes and the ALSA-driver internal changes +at probing and operating the HD-audio driver. + +The program requires a codec proc-file to simulate. Get a proc file +for the target codec beforehand, or pick up an example codec from the +codec proc collections in the tarball. Then, run the program with the +proc file, and the hda-emu program will start parsing the codec file +and simulates the HD-audio driver: + +------------------------------------------------------------------------ + % hda-emu codecs/stac9200-dell-d820-laptop + # Parsing.. + hda_codec: Unknown model for STAC9200, using BIOS defaults + hda_codec: pin nid 08 bios pin config 40c003fa + .... +------------------------------------------------------------------------ + +The program gives you only a very dumb command-line interface. You +can get a proc-file dump at the current state, get a list of control +(mixer) elements, set/get the control element value, simulate the PCM +operation, the jack plugging simulation, etc. + +The package is found in: + +- ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/misc/ + +A git repository is available: + +- git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/hda-emu.git + +See README file in the tarball for more details about hda-emu +program. -- cgit v0.10.2 From 384c89e2e4cb5879b86a38414d1b3bb2b23ec8ee Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Wed, 3 Dec 2008 17:34:03 +0000 Subject: ASoC: Push debugfs files out of the snd_soc_device structure This is in preparation for the removal of struct snd_soc_device.

So we had a commandline that looked like this: ... -I -Wall ... This had the undesired side effect that gcc assumed "-Wall" was a path to look for include files so this options was effectively ignored. This happens only when we build the generated module.mod.c files as part of the final modules builds and is as such harmless with current kbuild.

For example: file /sbin/kinit ${RFS_BASE}/usr/src/klibc/kinit/kinit 0755 0 0 given RFS_BASE is "/some/directory" in the environment would be expanded to file /sbin/kinit /some/directory/usr/src/klibc/kinit/kinit 0755 0 0 If several environment variables appear in a line, they are all expanded with processing happening from left to right. Undefined variables expand to a null string. Syntax errors stop processing, letting the existing error handling show the user offending line.

When a checksum change occurs, it can be hard to figure out what caused this change: underlying types may have changed, or additional type information may simply have become available at the point where a symbol is exported. Add a new --reference option to genksyms which allows it to report why checksums change, based on the type information dumps it creates with the --dump-types flag. Genksyms will read in such a dump from a previous run, and report which symbols have changed (and why). The behavior can be controlled for an entire build as follows: If KBUILD_SYMTYPES is set, genksyms uses --dump-types to produce *.symtypes dump files.

When a symbol is overridden, the symbol's old definition will be used for computing checksums instead of the new one, preserving the previous checksum. (Genksyms will still warn about the change.) This is meant to allow distributions to hide minor actual as well as fake ABI changes. (For example, when extra type information becomes available because additional headers are included, this may change checksums even though none of the types used have actully changed.) This approach also allows to get rid of "#ifdef __GENKSYMS__" hacks in the code, which are currently used in some vendor kernels to work around checksum changes.

This mirrors the behavior of other drivers including e1000 and tg3. Without the patch, ifconfig down leaves the physical link up, which confuses datacenter users who expect the link lights both on the NIC and the switch to go out when they bring an interface down. Furthermore, even though the phy is powered on, autonegotiation stops working, so a normally gigabit link might suddenly become 100 Mbit half-duplex when the interface goes down, and become gigabit when it comes up again. Ayaz said: I would not include this patch until further testing is performed. NVIDIA MCP chips use 3rd party PHY vendors. By powering down the phy, it could have adverse affects on certain phys. Arthur Jones said: I just ran across this patch. Tested on a Marvell 88E1121R (GigE PHY) and works great. This is a very important feature for me.

This patch deals with most of it, and I can now at least use BR2684 and PPPoATM with 32-bit userspace. I haven't added a .compat_ioctl method to struct atm_ioctl, because AFAICT none of the current users need any conversion -- so we can just call the ->ioctl() method in every case. I looked at br2684, clip, lec, mpc, pppoatm and atmtcp. In svc_compat_ioctl() the only mangling which is needed is to change COMPAT_ATM_ADDPARTY to ATM_ADDPARTY. Although it's defined as _IOW('a', ATMIOC_SPECIAL+4,struct atm_iobuf) it doesn't actually _take_ a struct atm_iobuf as an argument -- it takes a struct sockaddr_atmsvc, which _is_ the same between 32-bit and 64-bit code, so doesn't need conversion. Almost all of vcc_ioctl() would have been identical, so I converted that into a core do_vcc_ioctl() function with an 'int compat' argument. I've done the same with atm_dev_ioctl(), where there _are_ a few differences, but still it's relatively contained and there would otherwise have been a lot of duplication. I haven't done any of the actual device-specific ioctls, although I've added a compat_ioctl method to struct atmdev_ops. Signed-off-by: David Woodhouse Signed-off-by: David S.

It is a resolved cache entry, 10 packets used it... The second line represents an unresolved entry, and the columns Pkts(4th), Bytes(5th) and Wrong(6th) just show garbage. In struct mfc_cache, there's an union to store data for resolved and unresolved cases. And what ipmr_mfc_seq_show() is printing in these columns for the unresolved entries is some bytes from mfc_cache.mfc_un.res. Bad. (eg. In our case -559067475 is in fact 0xdead4ead which is the spinlock magic from mfc_cache.mfc_un.unres.unresolved.lock.magic). This patch replaces the garbage data written in these columns for the unresolved entries by '0' (zeros) which is more correct. This change doesn't break the ABI. Also, mfc->mfc_un.res.pkt, mfc->mfc_un.res.bytes, mfc->mfc_un.res.wrong_if are unsigned long. It applies on top of net-next-2.6. The patch for net-2.6 is slightly different because of the NIP6_FMT to %pI6 conversion that was made in the seq_printf.

Indeed, it expects to see -1 in 'Iif' column to identify unresolved entries but the kernel outputs 65535. It's a signed/unsigned issue: 'Iif', the source interface, is retrieved from member mfc_parent in struct mfc_cache. mfc_parent is a vifi_t: unsigned short, but is displayed in ipmr_mfc_seq_show() as "%-3d", signed integer. In unresolevd entries, the 65535 value (0xFFFF) comes from this define: #define ALL_VIFS ((vifi_t)(-1)) That may explains why the guy who added support for this in iproute2 thought a -1 should be expected. I don't know if this must be fixed in kernel or in iproute2. Who is right? What is the correct API? How was it designed originally? I let you decide if it should goes in the kernel or be fixed in iproute2. Signed-off-by: Benjamin Thery Signed-off-by: David S.

When this file is empty, the function graph tracer will act as usual. When the file has a function in it, the function graph tracer will only trace that function. For example: # echo blk_unplug > /debugfs/tracing/set_graph_function # cat /debugfs/tracing/trace [...] ------------------------------------------ | 2) make-19003 => kjournald-2219 ------------------------------------------ 2) | blk_unplug() { 2) | dm_unplug_all() { 2) | dm_get_table() { 2) 1.381 us | _read_lock(); 2) 0.911 us | dm_table_get(); 2) 1. 76 us | _read_unlock(); 2) + 12.912 us | } 2) | dm_table_unplug_all() { 2) | blk_unplug() { 2) 0.778 us | generic_unplug_device(); 2) 2.409 us | } 2) 5.992 us | } 2) 0.813 us | dm_table_put(); 2) + 29. 90 us | } 2) + 34.532 us | } You can add up to 32 functions into this file. Currently we limit it to 32, but this may change with later improvements. To add another function, use the append '>>': # echo sys_read >> /debugfs/tracing/set_graph_function # cat /debugfs/tracing/set_graph_function blk_unplug sys_read Using the '>' will clear out the function and write anew: # echo sys_write > /debug/tracing/set_graph_function # cat /debug/tracing/set_graph_function sys_write Note, if you have function graph running while doing this, the small time between clearing it and updating it will cause the graph to record all functions. This should not be an issue because after it sets the filter, only those functions will be recorded from then on. If you need to only record a particular function then set this file first before starting the function graph tracer. In the future this side effect may be corrected. The set_graph_function file is similar to the set_ftrace_filter but it does not take wild cards nor does it allow for more than one function to be set with a single write. There is no technical reason why this is the case, I just do not have the time yet to implement that. Note, dynamic ftrace must be enabled for this to appear because it uses the dynamic ftrace records to match the name to the mcount call sites.

This was changed to 'unsigned long' when the thread_info*.h for i386 and x86_64 were merged. Change it back. We can do this as only 27 bits of 'flags' are actually used. This change actually packs down thread_info by 64 bits: 32 bits are saved by the smaller flags, and 32 bits are saved by the following 'mm_segment_t field' becoming naturally 64-bit aligned.

The patch includes changes to the Bamboo and Canyonlands device-trees to add such a hole, others can be updated separately. The ISA memory hole is an additional outbound window configured in the bridge to generate PCI cycles in the low memory addresses, thus allowing to access things such as the hard-decoded VGA aperture at 0xa0000..0xbffff or other similar things. It's made accessible to userspace via the new legacy_mem file in sysfs for which support was added by a previous patch.

It also replaces the separate memcpy() calls for extracting key material into the hardware format with a loop that works regardless of key size.

The API version number is stored as part of the filename, we first try to load the most recent firmware and progressively try lower versions. The API version is also read from the firmware self and stored as part of the iwl_priv structure. Only firmware that is supported by driver will be loaded. The version number read from firmware is compared to supported versions in the driver not the API version used as part of filename.

This enables sending of direct probes on passive channels, as long as some traffic is detected on that channel. This improves the scanning for hidden SSIDs in A-band,which is all passive channels. This patch fixes the bug no 1748. http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1748 2) This fix will only work with uCode version 15.28.2.8 and above. Prior versions of uCode would work only if we heard the traffic within active dwell time, which is much shorter than passive dwell time and is shorter than typical beacon periods. This patch also provids full active dwell time even if we hear traffic late in passive dwell. 3) uCode API version is incremented to 2.

If they get some ACKs, then I hope to feed this into security-next. After these two, I think we're ready to tackle userns+capabilities) Fairsched creates a per-uid directory under /sys/kernel/uids/. So when you clone(CLONE_NEWUSER), it tries to create /sys/kernel/uids/0, which already exists, and you get back -ENOMEM. This was supposed to be fixed by sysfs tagging, but that was postponed (ok, rejected until sysfs locking is fixed).

The patch also ensures that the client feature-negotiation queue is flushed only when entering the OPEN state. Since confirmed Change options are removed as soon as they are confirmed (in the DCCP-Response), this ensures that Confirm options are retransmitted. Note on retransmitting Confirm options: --------------------------------------- Implementation experience showed that it is necessary to retransmit Confirm options. Thanks to Leandro Melo de Sales who reported a bug in an earlier revision of the patch set, resulting from not retransmitting these options. As long as the client is in PARTOPEN, it needs to retransmit the Confirm options for the Change options received on the DCCP-Response from the server. Otherwise, if the packet containing the Confirm options gets dropped in the network, the connection aborts due to undefined feature negotiation state.

When dccp_parse_options() fails, the reset code is already set; request_sent\ _state_process() currently overrides this with `Packet Error', which is not intended - changed to use the reset code supplied by dccp_parse_options(). 2. When feature negotiation fails, the socket should be marked as not usable, so that the application is notified that an error occurred. This is achieved by a new label 'unable_to_proceed': generating an error code of `Aborted', setting the socket state to CLOSED, returning with ECOMM in sk_err. 3. Avoids parsing the Ack twice in Respond state by not doing option processing again in dccp_rcv_respond_partopen_state_process (as option processing has already been done on the request_sock in dccp_check_req). Since this addresses congestion-control initialisation, a corresponding FIXME has been removed. Signed-off-by: Gerrit Renker Acked-by: Ian McDonald Signed-off-by: David S.

Allowing the user to change NDP values leads to unpredictable and failing behaviour, since it is then possible to disable NDP counts even when they are needed (e.g. in CCID-3). This means that only those user settings are sensible that agree with the values for Send NDP Count implied by the choice of CCID. But those settings are already activated by the feature negotiation (CCID dependency tracking), hence this form of support is redundant. At startup the initialisation of the NDP count feature uses the default value of 0, which is done implicitly by the zeroing-out of the socket when it is allocated. If the choice of CCID or feature negotiation enables NDP count, this will then be updated via the NDP activation handler. Signed-off-by: Gerrit Renker Acked-by: Ian McDonald Signed-off-by: David S.

Using a sysctl in parallel to this implementation would open the door to crashes, since much of the code relies on tests of the boolean minisock / sysctl variable. Thus, this patch replaces all tests of type if (dccp_msk(sk)->dccpms_send_ack_vector) /* ... */ with if (dp->dccps_hc_rx_ackvec != NULL) /* ... */ The dccps_hc_rx_ackvec is allocated by the dccp_hdlr_ackvec() when feature negotiation concluded that Ack Vectors are to be used on the half-connection. Otherwise, it is NULL (due to dccp_init_sock/dccp_create_openreq_child), so that the test is a valid one. The activation handler for Ack Vectors is called as soon as the feature negotiation has concluded at the * server when the Ack marking the transition RESPOND => OPEN arrives; * client after it has sent its ACK, marking the transition REQUEST => PARTOPEN. Adding the sequence number of the Response packet to the Ack Vector has been removed, since (a) connection establishment implies that the Response has been received; (b) the CCIDs only look at packets received in the (PART)OPEN state, i.e. this entry will always be ignored; (c) it can not be used for anything useful - to detect loss for instance, only packets received after the loss can serve as pseudo-dupacks. There was a FIXME to change the error code when dccp_ackvec_add() fails. I removed this after finding out that: * the check whether ackno < ISN is already made earlier, * this Response is likely the 1st packet with an Ackno that the client gets, * so when dccp_ackvec_add() fails, the reason is likely not a packet error.

The reason is that in sd_parent_degenerate(), it found that the child and parent does not have comon sched_domain flags due to SD_SERIALIZE. However, for non-numa smp box, the top level is a dummy with a single sched_group. Filter out SD_SERIALIZE if it is on non-numa machine to properly degenerate top level node sched_domain. this will cut back some of the sd domain walk in the load balancer code.

After some debugging, I saw that the "current" task point was changed inside__swtich_to(), ie: "write_pda(pcurrent, next_p);" inside process_64.c Since the tracer store the original return address of the function inside current, we had crashes. Only __switch_to() has to be excluded from tracing. kernel/module.c and kernel/extable.c: Because of a function used internally by the function graph tracer: __kernel_text_address() To let the other functions inside these files to be traced, this patch introduces the __notrace_funcgraph function prefix which is __notrace if function graph tracer is configured and nothing if not.

Solving this inside of the BT_DBG() macro is non-trivial since it's varargs. And these ifdefs are ugly. So, just mark this 'sk' thing __maybe_unused and kill the ifdefs. Signed-off-by: David S.

This patch records all TIOCSTI calls to disambiguate the input. It generates one audit message per character pushed back; considering TIOCSTI is used very rarely, this simple solution is probably good enough. (The only program I could find that uses TIOCSTI is mailx/nail in "header editing" mode, e.g. using the ~h escape. mailx is used very rarely, and the escapes are used even rarer.)

As part of backporting Liam's work introduce an initial version of the card registration functions.

Declare variable cache_resolve_queue_len per-namespace: moves it into struct netns_ipv6. This variable counts the number of unresolved cache entries queued in the list mfc_unres_queue. This list is kept global to all netns as the number of entries per namespace is limited to 10 (hardcoded in routine ip6mr_cache_unresolved). Entries belonging to different namespaces in mfc_unres_queue will be identified by matching the mfc_net member introduced previously in struct mfc6_cache. Keeping this list global to all netns, also allows us to keep a single timer (ipmr_expire_timer) to handle their expiration. In some places cache_resolve_queue_len value was tested for arming or deleting the timer. These tests were equivalent to testing mfc_unres_queue value instead and are replaced in this patch. At the moment, cache_resolve_queue_len is only referenced in init_net. Signed-off-by: Benjamin Thery Signed-off-by: David S.

This consists mainly in replacing all the remaining init_net occurences with current netns pointer retrieved from sockets, net devices or mfc6_caches depending on the routines' contexts. Some routines receive a new 'struct net' parameter to propagate the current netns: * ip6mr_get_route * ip6mr_cache_report * ip6mr_cache_find * ip6mr_cache_unresolved * mif6_add/mif6_delete * ip6mr_mfc_add/ip6mr_mfc_delete * ip6mr_reg_vif All the IPv6 multicast forwarding variables moved to struct netns_ipv6 by the previous patches are now referenced in the correct namespace. Changelog: ========== * Take into account the net associated to mfc6_cache when matching entries in mfc_unres_queue list. * Call mroute_clean_tables() in ip6mr_net_exit() to free memory allocated per-namespace. * Call dev_net_set() in ip6mr_reg_vif() to initialize dev->nd_net correctly.

Implements the KS8695 ethernet device (ks8695net). This driver is only of use on the KS8695 which is an ARM9 based SoC. The documentation on this SoC is sparse and poor, with barely a register description and a rough outline of how the ethernet works, this driver was therefore written with strong reference to the Micrel supplied Linux 2.6.9 port, and to Andrew Victor's ks8695eth driver.

For 3945 driver, it sets REPLY_RATE_SCALE command every time we connect to a new network. In this command we set for every rate the number of try and next rate. The problem mac80211 reports same mode for both B and G mode as IEEE80211_BAND_2GHZ which will cause using invalid rate other than CCK in B only network. THis patch on association will examine sta valid rate on association, if no OFDM rate in valid available rates it considers it as B only mode so we can set REPLY_RATE_SCALE command with valid B only network and only choose CCK rate in rate scaling.

This results in Beacon frame timestamp being off by 25 milliseconds or so which can cause issues with multicast power save buffering in AP mode. Some client stations fail to receive multicast frames when there is this large an offset between TBTT and actual Beacon transmission time. Since ath9k does not yet support multiple BSSes anyway, the staggered Beacon frame scheduling is just increasing the number of interrupts at this point. The easiest fix for the timestamp offset is to disable staggered Beacon frames for now. We need to redesign beacon.c anyway when adding multi-BSS support with mac80211 since the existing code depends on different mechanism for Beacon frame transmission.

The firmware will quietly cancel a scan (while associated) if the dwell time for a channel to be scanned is larger than the time it may stay away from the operating channel (because of DTIM catching). Unfortunately the driver is not notified about the canceled scan and therefore the scan watchdog timeout will be hit and the driver causes a firmware restart which results in disassociation. This mainly happens on passive channels which use a dwell time of 120 whereas a typical beacon interval is around 100. The patch changes the dwell time for passive channels to be slightly smaller than the actual beacon interval to work around the firmware issue. Furthermore the number of allowed beacon misses is increased from one to three as otherwise most scans (while associated) won't complete successfully. However scanning while associated will still fail in corner cases such as a beacon intervals below 30. Signed-off-by: Helmut Schaa Signed-off-by: John W.

While this could be implemented in a way that does not cause too many problems, it is not very simple and will require synchronization with Beacon frame scheduling in the drivers (scan one channel at a time between Beacon frames). Furthermore, such scanning takes quite a bit longer time and existing userspace applications would be likely to timeout while waiting for the results. For now, just refuse requests for new scans (SIOCSIWSCAN) when in AP mode. In practice, this moves the rejection from iwl* drivers into mac80211 to make it apply to every mac80211-based driver. This issue shows up in associated stations getting disconnected when something (e.g., Network Manager) requests a scan while the interface is in AP mode. When doing this continuously (e.g., NM does it every 120 seconds), the network gets close to useless. Signed-off-by: Jouni Malinen Acked-by: Johannes Berg Signed-off-by: John W.

As such we require all frag_list members terminate on exact MSS boundaries. This is checked using BUG_ON. As there should only be one producer in the kernel of such packets, namely GRO, this requirement should not be difficult to maintain. Signed-off-by: Herbert Xu Signed-off-by: David S.

Most hardware won't (and aren't expected to) support handling GRO frag_list packets directly. Therefore we will perform GSO in software for those cases. However, for drivers that can support it (such as virtual NICs) we may not have to segment the packets at all. Whether the added overhead of GRO/GSO is worthwhile for bridges and routers when weighed against the benefit of potentially increasing the MTU within the host is still an open question. However, for the case of host nodes this is undoubtedly a win. Signed-off-by: Herbert Xu Signed-off-by: David S.

This is pretty similar to LRO except that this is protocol-independent. Instead of holding packets in an lro_mgr structure, they're now held in napi_struct. For drivers that intend to use this, they can set the NETIF_F_GRO bit and call napi_gro_receive instead of netif_receive_skb or just call netif_rx. The latter will call napi_receive_skb automatically. When napi_gro_receive is used, the driver must either call napi_complete/napi_rx_complete, or call napi_gro_flush in softirq context if the driver uses the primitives __napi_complete/__napi_rx_complete. Protocols will set the gro_receive and gro_complete function pointers in order to participate in this scheme. In addition to the packet, gro_receive will get a list of currently held packets. Each packet in the list has a same_flow field which is non-zero if it is a potential match for the new packet. For each packet that may match, they also have a flush field which is non-zero if the held packet must not be merged with the new packet. Once gro_receive has determined that the new skb matches a held packet, the held packet may be processed immediately if the new skb cannot be merged with it. In this case gro_receive should return the pointer to the existing skb in gro_list. Otherwise the new skb should be merged into the existing packet and NULL should be returned, unless the new skb makes it impossible for any further merges to be made (e.g., FIN packet) where the merged skb should be returned. Whenever the skb is merged into an existing entry, the gro_receive function should set NAPI_GRO_CB(skb)->same_flow. Note that if an skb merely matches an existing entry but can't be merged with it, then this shouldn't be set. If gro_receive finds it pointless to hold the new skb for future merging, it should set NAPI_GRO_CB(skb)->flush. Held packets will be flushed by napi_gro_flush which is called by napi_complete and napi_rx_complete. Currently held packets are stored in a singly liked list just like LRO. The list is limited to a maximum of 8 entries. In future, this may be expanded to use a hash table to allow more flows to be held for merging. Signed-off-by: Herbert Xu Signed-off-by: David S.

The criteria for merging is more stringent than LRO, in particular, we require all fields in the IP header to be identical except for the length, ID and checksum. In addition, the ID must form an arithmetic sequence with a difference of one. The ID requirement might seem overly strict, however, most hardware TSO solutions already obey this rule. Linux itself also obeys this whether GSO is in use or not. In future we could relax this rule by storing the IDs (or rather making sure that we don't drop them when pulling the aggregate skb's tail).

This patch fixes it. If UDP checksums are enabled in the tunnel's UDP socket, the L2TP driver now properly validates the checksum on receive and fills in the checksum on transmit. If the network device has hardware checksum support and is enabled, it is used instead of generating/checking the checksum in software. Signed-off-by: James Chapman Signed-off-by: David S.

The function in question decides whether a device should enable TX and RX flow control in a standard way (IEEE 802.3-2005 table 28B-3), so this should also be useful for other drivers.

After having changed _PAGE_PROTNONE in our Xen kernel to no longer overlap _PAGE_PAT, live locks and crashes were reported that could have been avoided if these macros properly used the symbolic constants. Since, as pointed out earlier, for Xen Dom0 support mainline likewise will need to eliminate the conflict between _PAGE_PAT and _PAGE_PROTNONE, this patch does all the necessary adjustments, plus it introduces a mechanism to check consistency between MAX_SWAPFILES_SHIFT and the actual encoding macros. This also fixes a latent bug in that x86-64 used a 6-bit mask in __swp_type(), and if MAX_SWAPFILES_SHIFT was increased beyond 5 in (the seemingly unrelated) linux/swap.h, this would have resulted in a collision with _PAGE_FILE. Non-PAE 32-bit code gets similarly adjusted for its pte_to_pgoff() and pgoff_to_pte() calculations.

These modifications however broke the detection of Cablestar 2 DVB-C cards. The reason is that the earlier version of the driver used to retry unsuccessful i2c operations. The demodulator of Cablestar 2 cards (stv0297) seems to be very dependent on these retries and adding them back fixes Cablestar detection. This patch restores this behaviour for the CableStar2.

This bit means that the TSC is invariant with C/P/T states and always runs at constant frequency. With Intel CPUs, we have 3 classes * CPUs where TSC runs at constant rate and does not stop n C-states * CPUs where TSC runs at constant rate, but will stop in deep C-states * CPUs where TSC rate will vary based on P/T-states and TSC will stop in deep C-states. To cover these 3, one feature bit (CONSTANT_TSC) is not enough. So, add a second bit (NONSTOP_TSC). CONSTANT_TSC indicates that the TSC runs at constant frequency irrespective of P/T-states, and NONSTOP_TSC indicates that TSC does not stop in deep C-states. CPUID_0x8000000_Bit8 indicates both these feature bit can be set. We still have CONSTANT_TSC _set_ and NONSTOP_TSC _not_set_ on some older Intel CPUs, based on model checks. We can use TSC on such CPUs for time, as long as those CPUs do not support/enter deep C-states.

After reviewing recent changes to the way kernel page tables are allocated and initialized, and the lack of bugs caught by this debugging code, I've concluded it is now totally useless to have around, and it's already been #if 0'd for quite some time. There's no rush to get this in mainline, but it's also totally harmless, so I'll let the x86 maintainers decide where it should be tucked.

Partition systems do not have physical memory at address 0. Instead, a chunk of high memory is remapped by the chipset so that it appears to be at address 0. This remapping is INVISIBLE to most of the OS. The only OS functions that need to be aware of the remaping are functions that directly interface to the chipset. The GRU is one example. Also, delete a couple of unused macros related to global memory addresses.

It can not be disabled when it is configured on. (besides disabling the function tracer that it uses) This patch adds a way to enable or disable the stack tracer at run time. It defaults off on bootup, but a kernel parameter 'stacktrace' has been added to enable it on bootup. A new sysctl has been added "kernel.stack_tracer_enabled" to let the user enable or disable the stack tracer at run time.

The integrated audio CODEC provides all the necessary functions for high-quality stereo recording and playback. Programmable on-chip amplifiers allow for the direct connection of headphones and microphones with a minimum of external components. A programmable low-noise bias voltage is available to feed one or more electret microphones. Additional audio features include programmable high-pass filter in the ADC input path.

Drivers use mmap followed by pgprot_* and remap_pfn_range or vm_insert_pfn, in order to export reserved memory to userspace. Currently, such mappings are not tracked and hence not kept consistent with other mappings (/dev/mem, pci resource, ioremap) for the sme memory, that may exist in the system. The following patchset adds x86 PAT attribute tracking and untracking for pfnmap related APIs. First three patches in the patchset are changing the generic mm code to fit in this tracking. Last four patches are x86 specific to make things work with x86 PAT code. The patchset aso introduces pgprot_writecombine interface, which gives writecombine mapping when enabled, falling back to pgprot_noncached otherwise. This patch: While working on x86 PAT, we faced some hurdles with trackking remap_pfn_range() regions, as we do not have any information to say whether that PFNMAP mapping is linear for the entire vma range or it is smaller granularity regions within the vma. A simple solution to this is to use vm_pgoff as an indicator for linear mapping over the vma region. Currently, remap_pfn_range only sets vm_pgoff for COW mappings. Below patch changes the logic and sets the vm_pgoff irrespective of COW. This will still not be enough for the case where pfn is zero (vma region mapped to physical address zero). But, for all the other cases, we can look at pfnmap VMAs and say whether the mappng is for the entire vma region or not.

I bisected the problem to the following commit: commit c8019bf3aff653cceb64f66489fc299ee5957b57 Author: Wang Chen Date: Thu Nov 20 04:24:17 2008 -0800 netdevice ppp: Convert directly reference of netdev->priv 1. Use netdev_priv(dev) to replace dev->priv. 2. Alloc netdev's private data by alloc_netdev(). Signed-off-by: Wang Chen Signed-off-by: David S. Miller The original ppp_generic code treated the netdev and struct ppp as independent data structures which were freed separately. In moving the ppp struct into the netdev, it is now possible for the private data to be freed before the call to ppp_shutdown_interface(), which is bad. The kfree(ppp) in ppp_destroy_interface() is also wrong; presumably ppp hasn't worked since the above commit. The following patch fixes both problems.

Each SPI transfer entails two kernel thread context switches. One major source of SPI transfers is the enc28j60_set_bank() functions which runs before every register access. This patch reduces the number of SPI transfers that enc28j60_set_bank() performs in two ways: 1. removes unnecessary bank switch for the registers that are present in all banks 2. when switching from banks 0 or 3 to banks 1 or 2 (i.e. only one bit changes) enc28j60_set_bank() does only one SPI transfer instead of two According to my tests these changes reduce the number of SPI transfers in about 25%.

The discard counters for the NIU neptune chip are only 16-bit (even though this is a 64-bit chip). These 16-bit counters can overflow quickly, especially considering this is a 10Gbit/s ethernet card. The overflow indication bit is, unfortunatly, not usable as the counter value does not wrap, but remains at max value 0xFFFF. Resulting in lost counts until the counter is reset. The read and reset scheme also poses a problem. Both in theory and in practice counters can be lost in between reading nr64() and clearing the counter nw64(). For this reason, the number of counter clearings nw64() is limited/reduced. On the fast-path the counters are only syncronized once it exceeds 0x7FFF. When read by userspace, its syncronized fully.

We need the PHY reset for at least MPC8360E-MDS boards with Marvell 88E1111 PHY, the PHY won't recover from timeouts w/o the reset.

Furthermore, rebooting the system with a ping running caused a GPF every time.

However, the default key entries in sc_keymap were always set and as such, frames could have been claimed to be decrypted by hardware when they were not. This can cause problems especially with TKIP since mac80211 is validating the Michael MIC in the frame and this will result in MIC failure and potentially TKIP countermeasures if the frame was not decrypted correctly.

Basically it means enabling power save mode after an idle period. Implementing it dynamically gives a good compromise of low power consumption and low latency. Some hardware have support for this in firmware, but some require the host to do it. The dynamic power save is implemented by adding an timeout to ieee80211_subif_start_xmit(). The timeout can be enabled from userspace with Wireless Extensions. For example, the command below enables the dynamic power save and sets the time timeout to 500 ms: iwconfig wlan0 power timeout 500m Power save now only works with devices which handle power save in firmware. It's also disabled by default and the heuristics when and how to enable is considered as a policy decision and will be left for the userspace to handle. In case the firmware has support for this, drivers can disable this feature with IEEE80211_HW_NO_STACK_DYNAMIC_PS. Big thanks to Johannes Berg for the help with the design and code.

While at this, also strip other generated symbols during module installation. One potentially debatable point is the handling of the flags passeed to gcc when translating the intermediate assembly file into an object: passing $(c_flags) unchanged doesn't work as gcc passes --gdwarf2 to gas whenever is sees any -g* option, even for -g0, and despite the fact that the compiler would have already produced all necessary debug info in the C->assembly translation phase. I took the approach of just filtering out all -g* options, but an alternative to such negative filtering might be to have a positive filter which might, in the ideal case allow just all the -Wa,* options to pass through.

Using CONFIG_KALLSYMS_STRIP_GENERATED reduces the overhead of CONFIG_KALLSYMS_ALL from 245k/310k to 65k/80k for the (i386/x86-64) kernels I tested with. The patch also does away with the need to special case the kallsyms- internal symbols by making them available even in the first linking stage. While it is a generated file, the patch includes the changes to scripts/genksyms/keywords.c_shipped, as I'm unsure what the procedure here is.

Periodically, the CMM will query the hypervisor for a loan request, which is a single signed value. When kexec'ing into a kdump kernel, the CMM driver in the kdump kernel is not aware of the pages the previous kernel had marked as "loaned", so the hypervisor and the CMM driver are out of sync. This results in the CMM driver getting a negative loan request, which can then get treated as a large unsigned value and can cause kdump to hang due to the CMM driver inflating too large. Since there really is no clean way for the CMM driver in the kdump kernel to clean this up, simply disable CMM in the kdump kernel. This fixes hangs we were seeing doing kdump with AMS.

It adds support for SMP by implementing a concept of stale context map to lazily flush the TLB on processors where a context may have been invalidated. This also contains the ground work for generalizing such lazy TLB flushing by just picking up a new PID and marking the old one stale. This will be implemented later. This is a first implementation that uses a global spinlock. Ideally, we should try to get at least the fast path (context ID already assigned) lockless or limited to a per context lock, but for now this will do. I tried to keep the UP case reasonably simple to avoid adding too much overhead to 8xx which does a lot of context stealing since it effectively has only 16 PIDs available.

I moved over the 32-bit MMU related ones, added base features for MMU type families, but didn't move over any 64-bit only feature yet.

Note that I'm using local invalidations for D->I cache coherency. At worst, if another processor is trying to execute the same and has the old entry in its TLB, it will just take a fault and re-do the TLB flush locally (it won't re-do the cache flush in any case).

This moves things around such that _tlbie is now defined in hash_low_32.S and is only used by the 32-bit hash code, and all nohash CPUs use the various _tlbil_* forms that are now moved to a new file, tlb_nohash_low.S. I moved all the definitions for that stuff out of include/asm/tlbflush.h as they are really internal mm stuff, into mm/mmu_decl.h The code should have no functional changes. I kept some variants inline for trivial forms on things like 40x and 8xx.

Only the main free map and CPU 0 stale map are allocated at boot time. Other CPU maps are allocated when those CPUs are brought up and freed if they are unplugged. This also moves the initialization of the MMU context management slightly later during the boot process, which should be fine as it's really only needed when userland if first started anyways.

We also manipulate _PAGE_NO_CACHE and _PAGE_GUARDED by hand in all sorts of places. This changes the logic so that instead, the PTE now contains _PAGE_COHERENT for all normal RAM pages thay have I = 0 on platforms that need it. The hash code clears it if the feature bit is not set. It also adds some clean accessors to setup various valid combinations of access flags and change various bits of code to use them instead. This should help having the PTE actually containing the bit combinations that we really want. I also removed _PAGE_GUARDED from _PAGE_BASE on 44x and instead set it explicitely from the TLB miss. I will ultimately remove it completely as it appears that it might not be needed after all but in the meantime, having it in the TLB miss makes things a lot easier.

The various core errata related to prefetch should be sorted out by firmware by disabling icache prefetching in CCR0. We add the workaround to the kernel however just in case oooold firmwares don't do it. This is valid for -all- 4xx core variants. Later ones hard wire the absence of prefetch but it doesn't harm to clear the bits in CCR0 (they should already be cleared anyway).

The critical + * group has 3 irqs, External IRQ0, slice timer 0 irq, and wake from deep + * sleep. Main group include the other 3 external IRQs, slice timer 1, RTC, + * gpios, and the general purpose timers. Peripheral group contains the + * remaining irq sources from all of the on-chip peripherals (PSCs, Ethernet, + * USB, DMA, etc). + * + * virqs + * ----- + * The Linux IRQ subsystem requires that each irq source be assigned a + * system wide unique IRQ number starting at 1 (0 means no irq). Since + * systems can have multiple interrupt controllers, the virtual IRQ (virq) + * infrastructure lets each interrupt controller to define a local set + * of IRQ numbers and the virq infrastructure maps those numbers into + * a unique range of the global IRQ# space. + * + * To define a range of virq numbers for this controller, this driver first + * assigns a number to each of the irq groups (called the level 1 or L1 + * value). Within each group individual irq sources are also assigned a + * number, as defined by the MPC5200 user guide, and refers to it as the + * level 2 or L2 value. The virq number is determined by shifting up the + * L1 value by MPC52xx_IRQ_L1_OFFSET and ORing it with the L2 value. + * + * For example, the TMR0 interrupt is irq 9 in the main group. The + * virq for TMR0 is calculated by ((1 << MPC52xx_IRQ_L1_OFFSET) | 9). + * + * The observant reader will also notice that this driver defines a 4th + * interrupt group called 'bestcomm'. The bestcomm group isn't physically + * part of the MPC5200 interrupt controller, but it is used here to assign + * a separate virq number for each bestcomm task (since any of the 16 + * bestcomm tasks can cause the bestcomm interrupt to be raised). When a + * bestcomm interrupt occurs (peripheral group, irq 0) this driver determines + * which task needs servicing and returns the irq number for that task. This + * allows drivers which use bestcomm to define their own interrupt handlers. + * + * irq_chip structures + * ------------------- + * For actually manipulating IRQs (masking, enabling, clearing, etc) this + * driver defines four separate 'irq_chip' structures, one for the main + * group, one for the peripherals group, one for the bestcomm group and one + * for external interrupts. The irq_chip structures provide the hooks needed + * to manipulate each IRQ source, and since each group is has a separate set + * of registers for controlling the irq, it makes sense to divide up the + * hooks along those lines. + * + * You'll notice that there is not an irq_chip for the critical group and + * you'll also notice that there is an irq_chip defined for external + * interrupts even though there is no external interrupt group. The reason + * for this is that the four external interrupts are all managed with the same + * register even though one of the external IRQs is in the critical group and + * the other three are in the main group. For this reason it makes sense for + * the 4 external irqs to be managed using a separate set of hooks. The + * reason there is no crit irq_chip is that of the 3 irqs in the critical + * group, only external interrupt is actually support at this time by this + * driver and since external interrupt is the only one used, it can just + * be directed to make use of the external irq irq_chip. + * + * device tree bindings + * -------------------- + * The device tree bindings for this controller reflect the two level + * organization of irqs in the device. #interrupt-cells = <3> where the + * first cell is the group number [0..3], the second cell is the irq + * number in the group, and the third cell is the sense type (level/edge). + * For reference, the following is a list of the interrupt property values + * associated with external interrupt sources on the MPC5200 (just because + * it is non-obvious to determine what the interrupts property should be + * when reading the mpc5200 manual and it is a frequently asked question). + * + * External interrupts: + * <0 0 n> external irq0, n is sense (n=0: level high, + * <1 1 n> external irq1, n is sense n=1: edge rising, + * <1 2 n> external irq2, n is sense n=2: edge falling, + * <1 3 n> external irq3, n is sense n=3: level low) + */ #undef DEBUG #include @@ -24,11 +104,19 @@ #include #include #include -#include "mpc52xx_pic.h" -/* - * -*/ +/* HW IRQ mapping */ +#define MPC52xx_IRQ_L1_CRIT (0) +#define MPC52xx_IRQ_L1_MAIN (1) +#define MPC52xx_IRQ_L1_PERP (2) +#define MPC52xx_IRQ_L1_SDMA (3) + +#define MPC52xx_IRQ_L1_OFFSET (6) +#define MPC52xx_IRQ_L1_MASK (0x00c0) +#define MPC52xx_IRQ_L2_MASK (0x003f) + +#define MPC52xx_IRQ_HIGHTESTHWIRQ (0xd0) + /* MPC5200 device tree match tables */ static struct of_device_id mpc52xx_pic_ids[] __initdata = { @@ -53,10 +141,7 @@ static unsigned char mpc52xx_map_senses[4] = { IRQ_TYPE_LEVEL_LOW, };

This causes problems because the various bcom_... functions dereference the buffer descriptor pointer by using the array operator which doesn't work when the buffer descriptors are a different size. This patch adds the bcom_get_bd() function which uses the value in bcom_task.bd_size to calculate the offset into the BD table. This patch also changes the definition of bcom_bd to specify a data size of 0 instead of 1 so that it will never work if anyone attempts to dereference the bd list as an array (as opposed to something that might work even though it is wrong). Finally, this patch moves the definition of bcom_bd up in the file to eliminate a forward declaration. Based on patch originally written by Tim Yamin.

RFC 5046 refers to these PDUs as "unexpected". NOP-In PDUs with itt=RESERVED and Asynchronous Message PDUs occupy this category. The amount of active "unexpected" PDU's an iSER target may have at any time is governed by the MaxOutstandingUnexpectedPDUs key, which is not yet supported. Currently when an iSER target sends an "unexpected" PDU, the initiators recv buffer consumed by the PDU is not replaced. If over initial_post_recv_bufs_num "unexpected" PDUs are received then the receive queue will run out of receive work requests entirely. This patch ensures recv buffers consumed by "unexpected" PDUs are replaced in the next iser_post_receive_control() call.

Addresses passed to ioremap() should be physical addresses, so the best option is usually to convert the virtual address to a physical address before calling ioremap. This will give you a virtual address in P2 which matches the physical address and this works well for most internal hardware blocks on the SuperH architecture. However, some hardware blocks must be accessed through P4. Converting the P4 address to a physical and then back to a P2 does not work. One example of this is the sh7722 TMU block, it must be accessed through P4. Without this patch P4 addresses will be mapped using PTEs which requires the page allocator to be up and running.

We chan't share code for udivsi3 and udivsi3_i4, because they have a different clobber list. Copy udivsi3 from gcc-4.1.2.

But, this results unwanted code with gcc 4.1. In gcc, these three are treated as pseudo instructions that have their own clobber list apart from the usual calling convention. According to sh's machine description. The clobber list is as follows: - udivsi3_i4i : t,r1,pr,mach,macl - udivsi3_i4 : t,r0,r1,r4,r5,pr,dr0,dr2,dr4 - udivsi3 : t,r4,pr The caller of udivsi3 will be left with a broken r1 and mac*. gcc-4.1.x and older(at least to 3.4) generate udivsi3.

Based on a description from Henry Bell , it -has been modified to account for quirks in the current implementation. - -Version -======= - -This version of KGDB was written for 2.4.xx kernels for the SH architecture. -Further documentation is available from the linux-sh project website. - - -Debugging Setup: Host -====================== - -The two machines will be connected together via a serial line - this -should be a null modem cable i.e. with a twist. - -On your DEVELOPMENT machine, go to your kernel source directory and -build the kernel, enabling KGDB support in the "kernel hacking" section. -This includes the KGDB code, and also makes the kernel be compiled with -the "-g" option set -- necessary for debugging. - -To install this new kernel, use the following installation procedure. - -Decide on which tty port you want the machines to communicate, then -cable them up back-to-back using the null modem. On the DEVELOPMENT -machine, you may wish to create an initialization file called .gdbinit -(in the kernel source directory or in your home directory) to execute -commonly-used commands at startup. - -A minimal .gdbinit might look like this: - - file vmlinux - set remotebaud 115200 - target remote /dev/ttyS0 - -Change the "target" definition so that it specifies the tty port that -you intend to use. Change the "remotebaud" definition to match the -data rate that you are going to use for the com line (115200 is the -default). - -Debugging Setup: Target -======================== - -By default, the KGDB stub will communicate with the host GDB using -ttySC1 at 115200 baud, 8 databits, no parity; these defaults can be -changed in the kernel configuration. As the kernel starts up, KGDB will -initialize so that breakpoints, kernel segfaults, and so forth will -generally enter the debugger. - -This behavior can be modified by including the "kgdb" option in the -kernel command line; this option has the general form: - - kgdb=, - -The indicates the port to use, and can optionally specify -baud, parity and databits -- e.g. "ttySC0,9600N8" or "ttySC1,19200". - -The can be "halt" or "disabled". The "halt" action enters the -debugger via a breakpoint as soon as kgdb is initialized; the "disabled" -action causes kgdb to ignore kernel segfaults and such until explicitly -entered by a breakpoint in the code or by external action (sysrq or NMI). - -(Both and can appear alone, w/o the separating comma.) - -For example, if you wish to debug early in kernel startup code, you -might specify the halt option: - - kgdb=halt - -Boot the TARGET machine, which will appear to hang. - -On your DEVELOPMENT machine, cd to the source directory and run the gdb -program. (This is likely to be a cross GDB which runs on your host but -is built for an SH target.) If everything is working correctly you -should see gdb print out a few lines indicating that a breakpoint has -been taken. It will actually show a line of code in the target kernel -inside the gdbstub activation code. - -NOTE: BE SURE TO TERMINATE OR SUSPEND any other host application which -may be using the same serial port (for example, a terminal emulator you -have been using to connect to the target boot code.) Otherwise, data -from the target may not all get to GDB! - -You can now use whatever gdb commands you like to set breakpoints. -Enter "continue" to start your target machine executing again. At this -point the target system will run at full speed until it encounters -your breakpoint or gets a segment violation in the kernel, or whatever. - -Serial Ports: KGDB, Console -============================ - -This version of KGDB may not gracefully handle conflict with other -drivers in the kernel using the same port. If KGDB is configured on the -same port (and with the same parameters) as the kernel console, or if -CONFIG_SH_KGDB_CONSOLE is configured, things should be fine (though in -some cases console messages may appear twice through GDB). But if the -KGDB port is not the kernel console and used by another serial driver -which assumes different serial parameters (e.g. baud rate) KGDB may not -recover. - -Also, when KGDB is entered via sysrq-g (requires CONFIG_KGDB_SYSRQ) and -the kgdb port uses the same port as the console, detaching GDB will not -restore the console to working order without the port being re-opened. - -Another serious consequence of this is that GDB currently CANNOT break -into KGDB externally (e.g. via ^C or ); unless a breakpoint or -error is encountered, the only way to enter KGDB after the initial halt -(see above) is via NMI (CONFIG_KGDB_NMI) or sysrq-g (CONFIG_KGDB_SYSRQ). - -Code is included for the basic Hitachi Solution Engine boards to allow -the use of ttyS0 for KGDB if desired; this is less robust, but may be -useful in some cases. (This cannot be selected using the config file, -but only through the kernel command line, e.g. "kgdb=ttyS0", though the -configured defaults for baud rate etc. still apply if not overridden.) - -If gdbstub Does Not Work -======================== - -If it doesn't work, you will have to troubleshoot it. Do the easy -things first like double checking your cabling and data rates. You -might try some non-kernel based programs to see if the back-to-back -connection works properly. Just something simple like cat /etc/hosts -/dev/ttyS0 on one machine and cat /dev/ttyS0 on the other will tell you -if you can send data from one machine to the other. There is no point -in tearing out your hair in the kernel if the line doesn't work. - -If you need to debug the GDB/KGDB communication itself, the gdb commands -"set debug remote 1" and "set debug serial 1" may be useful, but be -warned: they produce a lot of output. - -Threads -======= - -Each process in a target machine is seen as a gdb thread. gdb thread related -commands (info threads, thread n) can be used. CONFIG_KGDB_THREAD must -be defined for this to work. - -In this version, kgdb reports PID_MAX (32768) as the process ID for the -idle process (pid 0), since GDB does not accept 0 as an ID. - -Detaching (exiting KGDB) -========================= - -There are two ways to resume full-speed target execution: "continue" and -"detach". With "continue", GDB inserts any specified breakpoints in the -target code and resumes execution; the target is still in "gdb mode". -If a breakpoint or other debug event (e.g. NMI) happens, the target -halts and communicates with GDB again, which is waiting for it. - -With "detach", GDB does *not* insert any breakpoints; target execution -is resumed and GDB stops communicating (does not wait for the target). -In this case, the target is no longer in "gdb mode" -- for example, -console messages no longer get sent separately to the KGDB port, or -encapsulated for GDB. If a debug event (e.g. NMI) occurs, the target -will re-enter "gdb mode" and will display this fact on the console; you -must give a new "target remote" command to gdb. - -NOTE: TO AVOID LOSSING CONSOLE MESSAGES IN CASE THE KERNEL CONSOLE AND -KGDB USING THE SAME PORT, THE TARGET WAITS FOR ANY INPUT CHARACTER ON -THE KGDB PORT AFTER A DETACH COMMAND. For example, after the detach you -could start a terminal emulator on the same host port and enter a ; -however, this program must then be terminated or suspended in order to -use GBD again if KGDB is re-entered. - - -Acknowledgements -================ - -This code was mostly generated by Henry Bell ; -largely from KGDB by Amit S.

Date: Wed, 17 Dec 2008 14:41:54 +0900 Subject: sh: Kill off cf-enabler with extreme prejudice. Now that the rest of the boards that were using cf-enabler "generically" have switched to setting up their mappings on their own, only the mach-se boards were left using it. All of the cf-enabler using mach-se boards use a special initialization of the MRSHPC windows rather than going through the special PTE as other SH-4 platforms do. This consolidates the MRSHPC setup logic, hooks it up on the boards that care, and gets rid of any and all remaining references to cf-enabler. This has been long overdue, as cf-enabler has been the bane of arch/sh/kernel for the last 7 years. Good riddance.

The LCDC hardware block managed by the sh_mobile_lcdcfb driver supports RGB or SYS panel configurations. SYS panels come with an external display controller that is resposible for refreshing the actual LCD panel. RGB panels are controlled directly by the LCDC and they need to be refreshed by the LCDC hardware. In the case of SYS panels we can save some power by configuring the LCDC hardware block in one-shot mode. In this one-shot mode panel refresh is managed by software. This works well together with deferred io since it allows us to stop clocks for most of the time and only enable clocks when we actually want to trigger an update. When there is no fbdev activity the clocks are kept stopped which allows us to deep sleep. The refresh rate in deferred io mode is set using platform data. The same platform data can also be used to disable deferred io mode. As with other deferred io frame buffers user space code should use fsync() on the frame buffer device to trigger an update.
