From 056ff3e3bd1563969a311697323ff929df94415c Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Wed, 3 Feb 2010 12:58:06 +0100 Subject: netfilter: nf_conntrack: fix memory corruption with multiple namespaces As discovered by Jon Masters , the "untracked" conntrack, which is located in the data section, might be accidentally freed when a new namespace is instantiated while the untracked conntrack is attached to a skb because the reference count it re-initialized. The best fix would be to use a seperate untracked conntrack per namespace since it includes a namespace pointer. Unfortunately this is not possible without larger changes since the namespace is not easily available everywhere we need it. For now move the untracked conntrack initialization to the init_net setup function to make sure the reference count is not re-initialized and handle cleanup in the init_net cleanup function to make sure namespaces can exit properly while the untracked conntrack is in use in other namespaces.

If we use a shared slab cache, one object can instantly flight between one hash table (netns ONE) to another one (netns TWO), and concurrent reader (doing a lookup in netns ONE, 'finding' an object of netns TWO) can be fooled without notice, because no RCU grace period has to be observed between object freeing and its reuse. We dont have this problem with UDP/TCP slab caches because TCP/UDP hashtables are global to the machine (and each object has a pointer to its netns). If we use per netns conntrack hash tables, we also *must* use per netns conntrack slab caches, to guarantee an object can not escape from one namespace to another one.

Changing the hash size will only resize the hash in the current namespace however, so other namespaces will use an invalid hash size. This can cause crashes when enlarging the hashsize, or false negative lookups when shrinking it. Move the hash size into the per-namespace data and only use the global hash size to initialize the per-namespace value when instanciating a new namespace. Additionally restrict hash resizing to init_net for now as other namespaces are not handled currently.

However, in some situations (e.g. no traffic) it would be nicer to scan a few channels in a row to speed up the scan itself. Hence, after scanning a channel, check if we have queued up any tx frames and return to the operating channel in that case. Unfortunately we don't know if the AP has buffered any frames for us. Hence, scan only as many channels in a row as the pm_qos latency and the negotiated listen interval allows us to. Signed-off-by: Helmut Schaa Signed-off-by: John W.

This is not very clear in the code right now, unfortunately. Introduce a new IWL_TX_FIFO_UNUSED constant and make the queue/FIFO mapping arrays able to hold that value, and change the setup code to reserve all queues in the arrays (the queue number is the index) and use the new unused constant to not map those queues to any FIFO. Additionally, clear up the AC/queue mapping code to be more understandable. The mapping is the identity mapping right now, but with the mapping function I think it's easier to understand what happens there. Finally, HCCA isn't implemented at all and I think newer microcode removed it, so let's remove all mention of it in the code, some comments remain for 4965.

For drivers like RTL8187 that don't supply their own RC algorithms, this will cause ieee80211_register_hw to fail (making the driver unusable). This will tell kconfig to provide a warning if no rate control algorithms have been selected. That'll at least warn the user; users that know that their drivers supply a rate control algorithm can safely ignore the warning, and those who don't know (or who expect to be using multiple drivers) can select a default RC algorithm.

This is not correct since the HW does padding on RX (and expect the same padding to be present on TX) at the following position : - management : 24 + 6 if 4-addr format - control : 24 + 6 if 4-addr format - data : 24 + 6 if 4-addr format + 2 if QoS - invalid : 24 + 6 if 4-addr format whereas ieee80211_get_hdrlen_from_skb() is : - management : 24 - control : 16 except for ACK/CTS where it is 10 - data : 24 + 6 if 4-addr format + 2 if QoS + 2 if QoS & order - invalid : 24 So, correct frames are not affected : management frames do not use 4-addr format, control frames have no body and invalid frames are ... not valid by definition. However, in order to use monitor interface for debugging purpose, one must be able to send/receive any frames, be it correct or not. Such frames are affected by incorrect padding. Moreover, since padding is added on TX, we need to remove it before calling ieee80211_tx_status. This affect TX packets received by monitor interfaces. It has been tested between an ath5k based card (AR5212) and an ar9170usb based card (netgear WNDA3100) using a frame generator and a monitor interface for each card. v2: Added ath5k_add_padding / ath5k_remove_padding Signed-off-by: Benoit Papillault Signed-off-by: John W.

However, there exists in ath5k_hw_setup_4word_tx_desc (which is called for AR5212 like devices) a set number of retries defined by AR5K_TUNE_HWTXTRIES. The set number of tries is added to the tx_tries0 variable setup by the rate control algorithm. This changes the number of retries the rate control algorithm considers necessary. By removing the AR5K_TUNE_HWTXTRIES from the retry calculation the rate control algorithm is given control over the number of retries. Signed-off-by: Andrew Blaich Signed-off-by: John W.

It was renamed to "libipw", but some occurrences of the old name remained. Rename alloc_ieee80211() to alloc_libipw() and free_ieee80211() to free_libipw(). Adjust comments and label names. Change prefixes in diagnostic messages. Keep /proc/net/ieee80211 under the original name to avoid breaking user interface. Move the affected EXPORT_SYMBOL macros to their proper places.

Both are used in different cases. For both of these, when there is a congestion map update, we want to call rds_cong_map_updated() but not actually send anything -- since loopback local and foreign congestion maps point to the same spot, they're already in sync. The old code never called sw loop's xmit_cong_map(),so rds_cong_map_updated() wasn't being called for it. sw loop ports would not work right with the congestion monitor. Fixing that meant that hw loopback now would send congestion maps to itself. This is also undesirable (racy), so we check for this case in the ib-specific xmit code.

RPS distributes the load of received packet processing across multiple CPUs. Problem statement: Protocol processing done in the NAPI context for received packets is serialized per device queue and becomes a bottleneck under high packet load. This substantially limits pps that can be achieved on a single queue NIC and provides no scaling with multiple cores. This solution queues packets early on in the receive path on the backlog queues of other CPUs. This allows protocol processing (e.g. IP and TCP) to be performed on packets in parallel. For each device (or each receive queue in a multi-queue device) a mask of CPUs is set to indicate the CPUs that can process packets. A CPU is selected on a per packet basis by hashing contents of the packet header (e.g. the TCP or UDP 4-tuple) and using the result to index into the CPU mask. The IPI mechanism is used to raise networking receive softirqs between CPUs. This effectively emulates in software what a multi-queue NIC can provide, but is generic requiring no device support. Many devices now provide a hash over the 4-tuple on a per packet basis (e.g. the Toeplitz hash). This patch allow drivers to set the HW reported hash in an skb field, and that value in turn is used to index into the RPS maps. Using the HW generated hash can avoid cache misses on the packet when steering it to a remote CPU. The CPU mask is set on a per device and per queue basis in the sysfs variable /sys/class/net//queues/rx-/rps_cpus. This is a set of canonical bit maps for receive queues in the device (numbered by ). If a device does not support multi-queue, a single variable is used for the device (rx-0). Generally, we have found this technique increases pps capabilities of a single queue device with good CPU utilization. Optimal settings for the CPU mask seem to depend on architectures and cache hierarcy. Below are some results running 500 instances of netperf TCP_RR test with 1 byte req. and resp. Results show cumulative transaction rate and system CPU utilization. e1000e on 8 core Intel Without RPS: 108K tps at 33% CPU With RPS: 311K tps at 64% CPU forcedeth on 16 core AMD Without RPS: 156K tps at 15% CPU With RPS: 404K tps at 49% CPU bnx2x on 16 core AMD Without RPS 567K tps at 61% CPU (4 HW RX queues) Without RPS 738K tps at 96% CPU (8 HW RX queues) With RPS: 854K tps at 76% CPU (4 HW RX queues) Caveats: - The benefits of this patch are dependent on architecture and cache hierarchy. Tuning the masks to get best performance is probably necessary. - This patch adds overhead in the path for processing a single packet. In a lightly loaded server this overhead may eliminate the advantages of increased parallelism, and possibly cause some relative performance degradation. We have found that masks that are cache aware (share same caches with the interrupting CPU) mitigate much of this. - The RPS masks can be changed dynamically, however whenever the mask is changed this introduces the possibility of generating out of order packets. It's probably best not change the masks too frequently.

This change helps to speed up delivery of retransmitted messages by ensuring that they are not sent repeatedly over a bearer that is no longer working, but not yet recognized as failed.

Originally intended as a means of avoiding wasted work in retransmitting messages that were still on the driver's outbound queue, it also prevented TIPC from retransmitting messages through other means -- such as the secondary bearer of the broadcast link, or another interface in a set of bonded interfaces. This fix removes existing checks for cloned sk_buffs that prevented such retransmission. Origionally-Signed-off-by: Allan Stephens Signed-off-by: Neil Horman Signed-off-by: David S.

Wysocki" Date: Sun, 14 Mar 2010 14:35:17 +0000 Subject: e1000e / PCI / PM: Add basic runtime PM support (rev. 4) Use the PCI runtime power management framework to add basic PCI runtime PM support to the e1000e driver. Namely, make the driver suspend the device when the link is off and set it up for generating a wakeup event after the link has been detected again. [This feature is disabled until the user space enables it with the help of the /sys/devices/.../power/contol device attribute.] Based on a patch from Matthew Garrett. Signed-off-by: Rafael J.

The main change is a 21 bit address split into a 5 bit device ID and a 16 bit register offset. The definition is designed so that normal and extended devices can run on the same MDIO bus. Extend mdio-bitbang to do the new protocol. At the MDIO bus level the protocol is requested by or'ing MII_ADDR_C45 into the register offset. Make phy_read/phy_write/etc pass a full 32 bit register offset. This does not attempt to make the phy layer support C45 style PHYs, just to provide the MDIO bus support. Tested against a Broadcom 10GE phy with ID 0x206034, and several Broadcom 10/100/1000 Phys in normal mode. Signed-off-by: Jason Gunthorpe Signed-off-by: David S.

Of course, one can write a rule '-m recent --remove', but you have to know beforehand which entry to delete. This commit adds reaper logic which checks the head of the LRU list when a rule is invoked that has a '--seconds' value and XT_RECENT_REAP set. If an entry ceases to accumulate time stamps, then it will eventually bubble to the top of the LRU list where it is then reaped.

Change this to only add the broadcast station when interface is added by mac80211. With this we need some extra work to ensure broadcast station is always present since station table is cleared when RXON without ASSOC bit set is sent. To deal with this we re-add all driver known stations to uCode after such an RXON command is sent. We also do some cleanup and remove the various calls to clear the station table. We now only clear the station table in two scenarios: - only clear uCode portion of station table when RXON command without ASSOC bit is sent - clear uCode and driver portion when interface goes down or is removed. We need to do this clearing when interface goes down to deal with the device restart/reconfigure routines which do not remove the interface, but do add the interface during reconfiguration. Previously the keys were also cleared when station table in driver is cleared, this is not done anymore since mac80211 will take care that keys are set and cleared correctly. There is a known issue with this change. Associating with different AP without bringing interface down fails with a firmware error. This is because of the lack of full station notification support and the later patches in this series that complete the station notification support will fix this.

The benefot from these new callbacks are that they enable the driver to sleep while performing this work. This is a big patch since a few things need to be coordinated in this move. First we need to decouple station management from rate scaling, which caused a lot of code to be moved and/or deleted. Next we needed to tie in with mac80211's station management callback and let it direct our station management as well as trigger the rate scaling initialization.

The iwlwifi devices behave differently in this regard so this feature is made part of the ops infrastructure so we can have more control on how to monitor and recover from tx queue stall case per device.

This patch reduces timer events while keeping accuracy by rounding our timer and/or batching several address validations in addrconf_verify(). addrconf_verify() is called at earliest timeout among interface addresses' timeouts, but at maximum ADDR_CHECK_FREQUENCY (120 secs). In most cases, all of timeouts of interface addresses are long enough (e.g. several hours or days vs 2 minutes), this timer is usually called every ADDR_CHECK_FREQUENCY, and it is okay to be lazy. (Note this timer could be eliminated if all code paths which modifies variables related to timeouts call us manually, but it is another story.) However, in other least but important cases, we try keeping accuracy. When the real interface address timeout is coming, and the timeout is just before the rounded timeout, we accept some error. When a timeout has been reached, we also try batching other several events in very near future. Signed-off-by: YOSHIFUJI Hideaki Signed-off-by: David S.

The history buffer supports collecting information for all Atheros hardware, one history buffer slot for each chain on each channel used for MIMO operation. For current hardware this means one history buffer slot for each chain on both the control (or primary) channel and the extension (or secondary) channel. We know which noisefloor registers to poke for collecting noisefloor data through the chainmask. For AR9285 and AR9271 devices, both 1x1, the chaimmask is defined as 0x9 = 0b0001001. The first four bits represent each chain out of a maximum of 4 chains [0-3] on the primary channel. The last four bits represent each chain on the extension channel. A chainmask of 0x9 therefore indicates chain 1 is active on both the primary and the extension channel. AR9271 only requires collecting and storing noisefloor history buffer data for the first chain on both the control and extension channel (nfarray[0] and nfarray[3]) so fix the code and avoid which reads and writes to the history buffer for the other chains. Since the noisefloor varies depending on the number of chains your device supports also initialize the noisefloor history buffer with reasonable values seen on 1x1 devices such as AR9285.

The wl1271 has a feature which handles the connection monitor logic in hardware, basically sending periodically nullfunc frames and reporting to the host if AP is lost, after attempting to recover by sending probe-requests to the AP. Add support to mac80211 by adding a new flag IEEE80211_HW_CONNECTION_MONITOR which prevents conn_mon_timer from triggering during idle periods, and prevents sending probe-requests to the AP if beacon-loss is indicated by the hardware.

Via this interface a user-space connection manager may configure and receive pre-warning events of deteriorating WLAN connection quality, and start preparing for roaming in advance, before the connection is already lost. An example usage of such a trigger is starting scanning for nearby AP's in an attempt to find one with better connection quality, and associate to it before the connection characteristics of the existing connection become too bad or the association is even lost, leading in a prolonged delay in connectivity. The interface currently supports only RSSI, but it could be later extended to include other parameters, such as signal-to-noise ratio, if need for that arises.

The support functions include: + + - CFPKT CAIF Packet. Implementation of CAIF Protocol Packet. The + CAIF Packet has functions for creating, destroying and adding content + and for adding/extracting header and trailers to protocol packets. + + - CFLST CAIF list implementation. + + - CFGLUE CAIF Glue. Contains OS Specifics, such as memory + allocation, endianness, etc. + +The CAIF Protocol implementation contains: + + - CFCNFG CAIF Configuration layer. Configures the CAIF Protocol + Stack and provides a Client interface for adding Link-Layer and + Driver interfaces on top of the CAIF Stack. + + - CFCTRL CAIF Control layer. Encodes and Decodes control messages + such as enumeration and channel setup. Also matches request and + response messages. + + - CFSERVL General CAIF Service Layer functionality; handles flow + control and remote shutdown requests. + + - CFVEI CAIF VEI layer. Handles CAIF AT Channels on VEI (Virtual + External Interface). This layer encodes/decodes VEI frames. + + - CFDGML CAIF Datagram layer. Handles CAIF Datagram layer (IP + traffic), encodes/decodes Datagram frames. + + - CFMUX CAIF Mux layer. Handles multiplexing between multiple + physical bearers and multiple channels such as VEI, Datagram, etc. + The MUX keeps track of the existing CAIF Channels and + Physical Instances and selects the apropriate instance based + on Channel-Id and Physical-ID. + + - CFFRML CAIF Framing layer.

The Net device and CAIF socket have an instance of +'struct cflayer', just like the CAIF Core protocol stack. +Net device and Socket implement the 'receive()' function defined by +'struct cflayer', just like the rest of the CAIF stack. In this way, transmit and +receive of packets is handled as by the rest of the layers: the 'dn->transmit()' +function is called in order to transmit data. + +The layer on top of the CAIF Core implementation is +sometimes referred to as the "Client layer". + + +Configuration of Link Layer +--------------------------- +The Link Layer is implemented as Linux net devices (struct net_device). +Payload handling and registration is done using standard Linux mechanisms. + +The CAIF Protocol relies on a loss-less link layer without implementing +retransmission. This implies that packet drops must not happen. +Therefore a flow-control mechanism is implemented where the physical +interface can initiate flow stop for all CAIF Channels. diff --git a/Documentation/networking/caif/README b/Documentation/networking/caif/README new file mode 100644 index 0000000..757ccfa --- /dev/null +++ b/Documentation/networking/caif/README @@ -0,0 +1,109 @@ +Copyright (C) ST-Ericsson AB 2010 +Author: Sjur Brendeland/ sjur.brandeland@stericsson.com +License terms: GNU General Public License (GPL) version 2 +--------------------------------------------------------- + +=== Start === +If you have compiled CAIF for modules do: + +$modprobe crc_ccitt +$modprobe caif +$modprobe caif_socket +$modprobe chnl_net + + +=== Preparing the setup with a STE modem === + +If you are working on integration of CAIF you should make sure +that the kernel is built with module support. + +There are some things that need to be tweaked to get the host TTY correctly +set up to talk to the modem. +Since the CAIF stack is running in the kernel and we want to use the existing +TTY, we are installing our physical serial driver as a line discipline above +the TTY device. + +To achieve this we need to install the N_CAIF ldisc from user space. +The benefit is that we can hook up to any TTY. + +The use of Start-of-frame-extension (STX) must also be set as +module parameter "ser_use_stx". + +Normally Frame Checksum is always used on UART, but this is also provided as a +module parameter "ser_use_fcs". + +$ modprobe caif_serial ser_ttyname=/dev/ttyS0 ser_use_stx=yes +$ ifconfig caif_ttyS0 up + +PLEASE NOTE: There is a limitation in Android shell. + It only accepts one argument to insmod/modprobe! + +=== Trouble shooting === + +There are debugfs parameters provided for serial communication. +/sys/kernel/debug/caif_serial// + +* ser_state: Prints the bit-mask status where + - 0x02 means SENDING, this is a transient state. + - 0x10 means FLOW_OFF_SENT, i.e. the previous frame has not been sent + and is blocking further send operation.

If timeout is set to 400ms, device enters into sleep mode at around 330ms since from last TX. This patch removes the msleep(1), which causes the delay after ELP wakeup.

This is useful for making it possible to allocate the intermediate rx status data separately. Signed-off-by: Felix Fietkau Signed-off-by: John W.

This is fixed by checking result of __xfrm_policy_unlink() when needed. It will always succeed if the policy object is looked up from the hash list (so some checks are removed), but it needs to be checked if we are trying to unlink policy via a reference (appropriate checks added).

This means that if 64-bit support isn't available, even buffers located below 4GB will get copied unnecessarily. -Some drivers set the flag even though they can't actually handle 64-bit DMA, which would mean that on platforms without IOMMU/SWIOTLB they would get a DMA mapping error if the memory they received happened to be located above 4GB. http://lkml.org/lkml/2010/3/3/530 We can use the dma_mask if we need bouncing or not here.

-- cgit v0.10.2 From 21b4aaa14329db793832e865f15000c5c0192ac3 Mon Sep 17 00:00:00 2001 From: James Chapman Date: Fri, 2 Apr 2010 06:18:28 +0000 Subject: l2tp: Relocate pppol2tp driver to new net/l2tp directory This patch moves the existing pppol2tp driver from drivers/net into a new net/l2tp directory, which is where the upcoming L2TPv3 code will live. The existing CONFIG_PPPOL2TP config option is left in its current place to avoid "make oldconfig" issues when an existing pppol2tp user takes this change. (This is the same approach used for the pppoatm driver, which moved to net/atm.) There are no code changes. The existing drivers/net/pppol2tp.c is simply moved to net/l2tp.

In L2TPv3, protocols other than PPP can be carried, so this split creates a common L2TP core that will handle the common L2TP bits which protocol support modules such as PPP will use. Note that the existing pppol2tp module is split into l2tp_core and l2tp_ppp by this change. There are no feature changes here. Internally, however, there are significant changes, mostly to handle the separation of PPP-specific data from the L2TP session and to provide hooks in the core for modules like PPP to access.

The existing code has some assumptions about the L2TP header which are broken by L2TPv3. Also the sockaddr_pppol2tp structure of the original code is too small to support the increased size of the L2TPv3 tunnel and session id, so a new sockaddr_pppol2tpv3 structure is needed. In the socket calls, the size of this structure is used to tell if the operation is for L2TPv2 or L2TPv3. Signed-off-by: James Chapman Reviewed-by: Randy Dunlap Signed-off-by: David S.

L2TP/IP uses IP protocol 115. Since L2TP/UDP and L2TP/IP packets differ in layout, the datapath packet handling code needs changes too. Userspace uses an L2TPIP socket instead of a UDP socket when IP encapsulation is required.

The number of parameters is significant. So let's use netlink. Userspace uses this API to control L2TP tunnel/session contexts in the kernel. The previous pppol2tp driver was managed using [gs]etsockopt(). This API is retained for backwards compatibility. Unlike L2TPv2 which carries only PPP frames, L2TPv3 can carry raw ethernet frames or other frame types and these do not always have an associated socket family. Therefore, we need a way to use L2TP sessions that doesn't require a socket type for each supported frame type. Hence netlink is used.

These interfaces are named l2tpethN by default, though userspace can specify an alternative name when the L2TP session is created, if preferred. When the pseudowire is established, regular Linux networking utilities may be used to configure the interface, i.e. give it IP address info or add it to a bridge.

Rather than adding info to that file for the new functionality added in this patch series, we add new files in debugfs, leaving the old /proc file for backwards compatibility (L2TPv2 only). Currently only one file is provided: l2tp/tunnels, which lists internal debug info for all l2tp tunnels and sessions. More files may be added later. The info is for debug and problem analysis only - userspace apps should use netlink to obtain status about l2tp tunnels and sessions. Although debugfs does not support net namespaces, the tunnels and sessions dumped in l2tp/tunnels are only those in the net namespace of the process reading the file.

This means L2TP tunnels and sessions can be created manually, without needing an L2TP control protocol implemented in userspace. This might be useful where the user wants a simple ethernet over IP tunnel. A patch to iproute2 adds a new command set under "ip l2tp" to make use of this feature. This will be submitted separately.

The chip architecture has also changed enough that any debugging effort that might use it would have to tailor it to the capabilities of the hardware. This patch just removes the function entirely.

Those masks differ in many bits. Use ah->imask instead of ah->mask_reg in ath9k_hw_set_interrupts() and ath9k_hw_updatetxtriglevel(). That's what the code was meant to do. ah->imask is initialized in ath9k_start(), so we don't need to initialize it from ah->mask_reg.

The modification is in usbnet.c function usbnet_start_xmit(). This patch only adds the zero length flag. A subsequent patch will address the buggy code we found when devices do not advertise FLAG_SEND_ZLP in which case there is a possibility of transferring packets with non-deterministic length. This patch has been tested on kernel-2.6.34-rc3. This patch has been checked against net-2.6 tree. Signed-off-by: Elina Pasheva Signed-off-by: Rory Filer Signed-off-by: David S.

It also allows to destruct object properly, if the last reference was held in flow cache. This is also a prepartion for caching bundles in the flow cache. In return for virtualizing the methods, we save on: - not having to regenerate the whole flow cache on policy removal: each flow matching a killed policy gets refreshed as the getter function notices it smartly. - we do not have to call flow_cache_flush from policy gc, since the flow cache now properly deletes the object if it had any references Signed-off-by: Timo Teras Acked-by: Herbert Xu Signed-off-by: David S.

The xfrm_find_bundle() does a linear search which can kill system performance depending on how many bundles are required per policy. This modifies __xfrm_lookup() to store bundles directly in the flow cache. If we did not get a hit, we just create a new bundle instead of doing slow search. This means that we can now get multiple xfrm_dst's for same flow (on per-cpu basis). Signed-off-by: Timo Teras Signed-off-by: David S.

I have looked at both ath9k and HAL sources (they are nearly the same), and even though i have implemented some things differently, the basic algorithm is practically the same, for now. I hope that this can serve as a clean start to improve the algorithm later. This also adds a possibility to manually control ANI settings, right now only thru a debugfs file: * set lowest sensitivity (=highest noise immunity): echo sens-low > /sys/kernel/debug/ath5k/phy0/ani * set highest sensitivity (=lowest noise immunity): echo sens-high > /sys/kernel/debug/ath5k/phy0/ani * automatically control immunity (default): echo ani-on > /sys/kernel/debug/ath5k/phy0/ani * to see the parameters in use and watch them change: cat /sys/kernel/debug/ath5k/phy0/ani Manually setting sensitivity will turn the automatic control off. You can also control each of the five immunity parameters (noise immunity, spur immunity, firstep, ofdm weak signal detection, cck weak signal detection) manually thru the debugfs file. This is tested on AR5414 and nearly doubles the thruput in a noisy 2GHz band. Signed-off-by: Bruno Randolf Signed-off-by: John W.

In order to meet these requirements, user space applications may need to clear authentication or association state in some cases. Currently, this can be done with deauth/disassoc command, but that ends up sending out Deauthentication or Disassociation frame unnecessarily. Add a new nl80211 attribute to allow this sending of the frame be skipped, but with all other deauth/disassoc operations being completed. Similar state change is also needed for IEEE 802.11r FT protocol in the FT-over-DS case which does not use Authentication frame exchange in a transition to another BSS. For this to work with cfg80211, an authentication entry needs to be created for the target BSS without sending out an Authentication frame. The nl80211 authentication command can be used for this purpose, too, with the new attribute to indicate that the command is only for changing local state. This enables wpa_supplicant to complete FT-over-DS transition successfully. Signed-off-by: Jouni Malinen Signed-off-by: John W.

Fix these issues by using the regular aggregation session teardown code and blocking new aggregation sessions, all before the station is really destructed. As a side effect, this gets rid of the long code block to destroy aggregation safely. Additionally, rename tid_state_rx which can only have the values IDLE and OPERATIONAL to tid_active_rx to make it easier to understand that there is no bitwise stuff going on on the RX side -- the TX side remains because it needs to keep track of the driver and peer states.

There are obvious race conditions here, besides which: 1. The test for availability is done by passing a NULL handler, which now always returns -EINVAL, thus the device cannot be opened: 2. probe_irq_off() will report only the first ISA IRQ handled, potentially leading to a false negative. There was another bug that meant it ignored all error codes from request_irq() except -EBUSY, so it would 'succeed' despite this (possibly causing conflicts with other ISA devices). This was fixed by ab08999d6029bb2c79c16be5405d63d2bedbdfea 'WARNING: some request_irq() failures ignored in el2_open()', which exposed bug 1. This patch: 1. Replaces the use of probe_irq_{on,off}() with a real interrupt handler 2. Adds a delay before checking the interrupt-seen flag 3. Disables interrupts on all failure paths 4. Distinguishes error codes from the second request_irq() call, consistently with the first Compile-tested only. Signed-off-by: Ben Hutchings Signed-off-by: David S.

Otherwise, when hw scan is used, the stack gets error about hw being busy with ongoing scan. This causes the stack to abort scan without notifying the driver about it. This leads to a situation where the hw is scanning and the stack thinks it's not. Then when the scan finishes, the stack will complain by warnings.

This is rather implicit as part of sending a station right now, which is odd. Make it explicit instead and only for agn since 3945 doesn't use hw crypto for WEP. Due to that, iwl_send_static_wepkey_cmd is now only used in iwl-sta.c and can be static.

For default WEP keys, however, mac80211 won't allow using the same key index twice, so the check is not necessary at all -- add/remove are perfectly nested due to those checks. Other keys are allocated in the device in a global array that only has a certain number of slots, so for that we need to keep the allocation bitmap; but the 802.11 key index isn't relevant there.

This requires order-4 allocation for txq->cmd[]. In situations like s2ram, this usually leads to allocation failure in the memory subsystem. The patch fixed this problem by allocating the Tx queues memory only at the first time. Later iwl_down/iwl_up only initialize but don't free and reallocate them. The memory is freed at the device removal time. BTW, we have already done this for the Rx queue.

Miller" Date: Thu, 8 Apr 2010 11:32:30 -0700 Subject: tcp: Set CHECKSUM_UNNECESSARY in tcp_init_nondata_skb Back in commit 04a0551c87363f100b04d28d7a15a632b70e18e7 ("loopback: Drop obsolete ip_summed setting") we stopped setting CHECKSUM_UNNECESSARY in the loopback xmit. This is because such a setting was a lie since it implies that the checksum field of the packet is properly filled in. Instead what happens normally is that CHECKSUM_PARTIAL is set and skb->csum is calculated as needed. But this was only happening for TCP data packets (via the skb->ip_summed assignment done in tcp_sendmsg()). It doesn't happen for non-data packets like ACKs etc. Fix this by setting skb->ip_summed in the common non-data packet constructor. It already is setting skb->csum to zero. But this reminds us that we still have things like ip_output.c's ip_dev_loopback_xmit() which sets skb->ip_summed to the value CHECKSUM_UNNECESSARY, which Herbert's patch teaches us is not valid. So we'll have to address that at some point too. Signed-off-by: David S.

This has always worked fine on my fast machine, but now I know there is a hidden race... The most likely candidate here is ring_control->device_idx. Quintin Pitts had already analyzed the culprit and posted a patch back in Oct 2009. But sadly, no one's picked up on this. ( https://patchwork.kernel.org/patch/53079/ [2 & 3] ).

Update the RT3070 register initialization to be similar to the latest Ralink vendor driver. With this patch my rt3070 based devices start showing a sign of life.

Add RT3390 specific register initializations to rt2x00, based on the latest Ralink rt3390 vendor driver. Untested as I don't actually own an RT3390 based device, but given experiences on rt3070/rt3071 very hopeful that this will actually work..

The RX timestamps are extracted from the padding alingment bytes during the clean_rx_ring operation and copied into the skb_shared_hwtstamps struct of the skb. This extraction only happens if the rx_filter was set to something else than HWTSTAMP_FILTER_NONE with the SIOCSHWTSTAMP ioctl command. Hardware timestamping is only supported for eTSEC devices.

This calls for RCU again :) This patch converts sk_dst_lock to a spinlock, and use RCU for readers. __sk_dst_get() is supposed to be called with rcu_read_lock() or if socket locked by user, so use appropriate rcu_dereference_check() condition (rcu_read_lock_held() || sock_owned_by_user(sk)) This patch avoids two atomic ops per tx packet on UDP connected sockets, for example, and permits sk_dst_lock to be much less dirtied.

Userspace multicast routing daemons can bind to a specific table instance by issuing a setsockopt call using a new option MRT_TABLE. The table number is stored in the raw socket data and affects all following ipmr setsockopt(), getsockopt() and ioctl() calls. By default, a single table (RT_TABLE_DEFAULT) is created with a default routing rule pointing to it. Newly created pimreg devices have the table number appended ("pimregX"), with the exception of devices created in the default table, which are named just "pimreg" for compatibility reasons. Packets are directed to a specific table instance using routing rules, similar to how regular routing rules work. Currently iif, oif and mark are supported as keys, source and destination addresses could be supported additionally. Example usage: - bind pimd/xorp/... to a specific table: uint32_t table = 123; setsockopt(fd, IPPROTO_IP, MRT_TABLE, &table, sizeof(table)); - create routing rules directing packets to the new table: # ip mrule add iif eth0 lookup 123 # ip mrule add oif eth0 lookup 123 Signed-off-by: Patrick McHardy Signed-off-by: David S.

-- cgit v0.10.2 From 56b106ae7b1f6b7cef4ef7e79a03b59cfc940923 Mon Sep 17 00:00:00 2001 From: Giuseppe CAVALLARO Date: Tue, 13 Apr 2010 20:21:12 +0000 Subject: stmmac: rework normal and enhanced descriptors Currently the driver assumes that the mac10/100 can only use the normal descriptor structure and the gmac can only use the enhanced structures. This patch removes the descriptor's code from the dma files and adds two new files just for handling the normal and enhanced descriptors. Signed-off-by: Giuseppe Cavallaro Signed-off-by: David S.

There are several scenarios; some chips (mac10/100 or gmac) want to use the enhanced descriptors; others want the normal ones. For example, on ST platforms: MAC10/100 uses the normal desc structure and the GMAC uses the enhanced one. It can be useful to get this information from the platform. This could also be decided at run-time looking at the chip's ID number; but it could happen that chips with the same ID want to use different descriptor structure.

But on 82599 the logic to disable/enable hardware stripping is different, and the code was not updated correctly when the hardware vlan stripping was enabled as default. This change comprises the creation of two new helper functions and calling them from the right locations to disable and enable hardware stripping of vlan tags at appropriate times.

For encapsulated packets, they ended up overwriting the encapsulating header. The new code copies the Ethernet source MAC address and protocol number before calling dst->neighbour->output(). The Ethernet source MAC and protocol number are copied back in place in br_nf_pre_routing_finish_bridge_slow(). This also makes the IP DNAT more transparent because in the old scheme the source MAC of the bridge was copied into the source address in the Ethernet header. We also let skb->protocol equal ETH_P_IP resp. ETH_P_IPV6 during the execution of the PF_INET resp. PF_INET6 hooks. - Speed up IP DNAT by calling neigh_hh_bridge() instead of neigh_hh_output(): if dst->hh is available, we already know the MAC address so we can just copy it.

This can cause an issue at the event recipient. An example of this is when cfg80211 sends IWEVASSOCREQIE and IWEVASSOCRESPIE events with NULL event body to wpa_supplicant. The wpa_supplicant overwrites the assoc request and assoc response IEs for this station with NULL data. If the association is WPA/WPA2, the wpa_supplicant is not able to generate EAPOL handshake messages, since the IEs are NULL. With the patch, req_ie and resp_ie will be NULL by avoiding the assignment if the driver has not sent the IEs to cfg80211. The event sending code sends the events only if resp_ie and req_ie are not NULL. This will ensure that the events are not sent with NULL event body.

Since the memory was already DMA mapped _before_ the call to write_tx_desc the device didn't get the txwi data at all or only sporadically. The call order is basically as follows (from rt2x00queue.c): 1) write_tx_data 2) rt2x00queue_map_txskb 3) write_tx_desc Hence, we shouldn't touch the skb in write_tx_desc anymore. To fix this issue create a new rt2800pci_write_tx_data callback and use it for updating the txwi _before_ the memory gets DMA mapped. The tx descriptor is still written (as before) in write_tx_desc. This patch allows basic TX on an rt305x soc device but I'm pretty sure that it will fix pci based cards as well. I can associate just fine with an AP now but I wasn't able to get a wpa secured connection working yet. Signed-off-by: Helmut Schaa Acked-by: Gertjan van Wingerde Signed-off-by: John W.

Rodriguez" Date: Thu, 15 Apr 2010 17:38:13 -0400 Subject: ath9k_hw: remove wrapper ath9k_hw_write_regs() This is used only once by ath9k_hw_process_ini() to write an array of phy registers through REG_WRITE_ARRAY(), but we already call REG_WRITE_ARRAY() multiple times on the same caller so just remove this pointless wrapper. We'll eventually just move the ath9k_hw_process_ini() caller as an callback to abstract away between different hardware families. Although this change is subtle I should note that this does change the delay pattern on writing the next series of registers. REG_WRITE_ARRAY() uses a counter for each register write and does a udelay(1) every 64 writes. By removing this call it means that the counter is processed for all the iniBB_RfGain registers and is incremented on ath9k_hw_process_ini(), before this the after the call ath9k_hw_write_regs() was made the register counter was kept at the same index number prior to the call.

First move the RF ops to the private ops and rename them accordingly. We split PHY stuff up first for the AR5008 and AR9002 families. There are some callbacks that AR9002 share with the AR5008 familiy so we set those first, if AR9002 has some different callbacks it will override them upon hardware init.

Rodriguez" Date: Thu, 15 Apr 2010 17:39:13 -0400 Subject: ath9k_hw: restore mac address reading logic Once upon a time the AR_EEPROM_MAC macro was added to let us add a random attribute to the three 4-bytes of MAC addresses entries we read from the EEPROM. This was good while a random high-enough value was used which did not conflict with any of the already existing enum eeprom_param values. With AR9003 support the enums overlap and it means we either increment the random offset or just restore the reading logic to match what the HAL has. I choose to do the later to synchronize the logic on both code bases. This should fix reading the MAC address from the EEPROM on AR9003 hardware. Signed-off-by: Luis R.

It has been tested in an IBSS network where artifical IBSS merges have been done in order to trigger hundreds of rollover for the TSF lower part. It follows the logic mentionned by Derek, with only 2 register reads needed at each additional steps instead of 3 (the minimum number of register reads is still 3).

RFS steers received packets for layer 3 and 4 processing to the CPU where the application for the corresponding flow is running. RFS is an extension of Receive Packet Steering (RPS). The basic idea of RFS is that when an application calls recvmsg (or sendmsg) the application's running CPU is stored in a hash table that is indexed by the connection's rxhash which is stored in the socket structure. The rxhash is passed in skb's received on the connection from netif_receive_skb. For each received packet, the associated rxhash is used to look up the CPU in the hash table, if a valid CPU is set then the packet is steered to that CPU using the RPS mechanisms. The convolution of the simple approach is that it would potentially allow OOO packets. If threads are thrashing around CPUs or multiple threads are trying to read from the same sockets, a quickly changing CPU value in the hash table could cause rampant OOO packets-- we consider this a non-starter. To avoid OOO packets, this solution implements two types of hash tables: rps_sock_flow_table and rps_dev_flow_table. rps_sock_table is a global hash table. Each entry is just a CPU number and it is populated in recvmsg and sendmsg as described above. This table contains the "desired" CPUs for flows. rps_dev_flow_table is specific to each device queue. Each entry contains a CPU and a tail queue counter. The CPU is the "current" CPU for a matching flow. The tail queue counter holds the value of a tail queue counter for the associated CPU's backlog queue at the time of last enqueue for a flow matching the entry. Each backlog queue has a queue head counter which is incremented on dequeue, and so a queue tail counter is computed as queue head count + queue length. When a packet is enqueued on a backlog queue, the current value of the queue tail counter is saved in the hash entry of the rps_dev_flow_table. And now the trick: when selecting the CPU for RPS (get_rps_cpu) the rps_sock_flow table and the rps_dev_flow table for the RX queue are consulted. When the desired CPU for the flow (found in the rps_sock_flow table) does not match the current CPU (found in the rps_dev_flow table), the current CPU is changed to the desired CPU if one of the following is true: - The current CPU is unset (equal to RPS_NO_CPU) - Current CPU is offline - The current CPU's queue head counter >= queue tail counter in the rps_dev_flow table. This checks if the queue tail has advanced beyond the last packet that was enqueued using this table entry. This guarantees that all packets queued using this entry have been dequeued, thus preserving in order delivery. Making each queue have its own rps_dev_flow table has two advantages: 1) the tail queue counters will be written on each receive, so keeping the table local to interrupting CPU s good for locality. 2) this allows lockless access to the table-- the CPU number and queue tail counter need to be accessed together under mutual exclusion from netif_receive_skb, we assume that this is only called from device napi_poll which is non-reentrant. This patch implements RFS for TCP and connected UDP sockets. It should be usable for other flow oriented protocols. There are two configuration parameters for RFS. The "rps_flow_entries" kernel init parameter sets the number of entries in the rps_sock_flow_table, the per rxqueue sysfs entry "rps_flow_cnt" contains the number of entries in the rps_dev_flow table for the rxqueue. Both are rounded to power of two. The obvious benefit of RFS (over just RPS) is that it achieves CPU locality between the receive processing for a flow and the applications processing; this can result in increased performance (higher pps, lower latency). The benefits of RFS are dependent on cache hierarchy, application load, and other factors. On simple benchmarks, we don't necessarily see improvement and sometimes see degradation. However, for more complex benchmarks and for applications where cache pressure is much higher this technique seems to perform very well. Below are some benchmark results which show the potential benfit of this patch. The netperf test has 500 instances of netperf TCP_RR test with 1 byte req. and resp. The RPC test is an request/response test similar in structure to netperf RR test ith 100 threads on each host, but does more work in userspace that netperf. e1000e on 8 core Intel No RFS or RPS 104K tps at 30% CPU No RFS (best RPS config): 290K tps at 63% CPU RFS 303K tps at 61% CPU RPC test tps CPU% 50/90/99% usec latency Latency StdDev No RFS/RPS 103K 48% 757/900/3185 4472.35 RPS only: 174K 73% 415/993/2468 491.66 RFS 223K 73% 379/651/1382 315.61 Signed-off-by: Tom Herbert Signed-off-by: Eric Dumazet Signed-off-by: David S.

Traditionally, this destructor is called at tx completion time, when skb is freed. When tx completion is performed by another cpu than the sender, this forces some cache lines to change ownership. XPS was an attempt to give tx completion to initial cpu. David idea is to call destructor right before giving skb to device (call to ndo_start_xmit()). Because device queues are usually small, orphaning skb before tx completion is not a big deal. Some drivers already do this, we could do it in upper level. There is one known exception to this early orphaning, called tx timestamping. It needs to keep a reference to socket until device can give a hardware or software timestamp. This patch adds a skb_orphan_try() helper, to centralize all exceptions to early orphaning in one spot, and use it in dev_hard_start_xmit().

This has a well-known drawback: the jumpstack is overwritten on reentry, making it necessary for targets to return absolute verdicts. Also, the ruleset (which might be heavy memory-wise) needs to be replicated for each CPU that can possibly invoke ip6t_do_table. This patch decouples the jumpstack from struct ip6t_entry and instead puts it into xt_table_info. Not being restricted by 'comefrom' anymore, we can set up a stack as needed. By default, there is room allocated for two entries into the traverser. arp_tables is not touched though, because there is just one/two modules and further patches seek to collapse the table traverser anyhow.

HW is configured to stop all DMA transactions to the host and sending packets to the network once parity error is detected, which is meant to prevent silent data corruption. At the same time HW generates the attention interrupt to every function of the device where parity has been detected so that driver can start the recovery flow. The recovery is actually resetting the chip and restarting the driver on all active functions of the chip where the parity error has been reported.

The detailed phenomenon is 1. After a while the clients connected to one of these VAPs will get into a state that no broadcast/multicast packets can be transfered successfully while the unicast packets can be transfered normally. 2. Minutes latter the unitcast packets transfer will fail as well, because the ARP entry is expired and it can't be freshed due to the broadcast trouble. It's caused by the group key overwritten and someone discussed this issue in ath9k-devel maillist before, but haven't work out a fix yet. I referred the method in madwifi, and made a patch for ath9k. The method is to set the high bit of the sender(AP)'s address, and associated that mac and the group key. It requires the hardware supports multicast frame key search. It seems true for AR9160. Not sure whether it's the correct way to fix this issue. But it seems to work in my test. The patch is attached, feel free to revise it. Signed-off-by: Daniel Yingqiang ma Signed-off-by: John W.

Commit 6651ffc8e8bdd5fb4b7d1867c6cfebb4f309512c ("ipv6: Fix tcp_v6_send_response transport header setting.") fixed one half of why ipv6 tcp response checksums were invalid, but it's not the whole story. If we're going to use CHECKSUM_PARTIAL for these things (which we are since commit 2e8e18ef52e7dd1af0a3bd1f7d990a1d0b249586 "tcp: Set CHECKSUM_UNNECESSARY in tcp_init_nondata_skb"), we can't be setting buff->csum as we always have been here in tcp_v6_send_response.

Use a spinlock per fasync_struct to synchronize kill_fasync_rcu() and fasync_{remove|add}_entry().

At least some b43 devices are 'in the wild' that don't have SPROMs at all. When the SSB bus support loads, it attempts to read these (non-existant) SPROMs and causes hard hangs on the box -- no console output, etc. This patch adds some intelligence to determine whether or not the SPROM is present before attempting to read it. This avoids those hard hangs on those devices with no SPROM attached to their SSB bus. The SSB-attached devices (e.g. b43, et al.) won't work, but at least the box will survive to test further patches. :-) Signed-off-by: John W.

However, for hardware drivers with IEEE80211_HW_HAS_RATE_CONTROL this is not performed, as the rate control algorithm is not executed, and because the used rate is not known before the frame has actually been transmitted. This causes atleast a fixed 1Mb/s to be reported to user space. A few other instances of code also rely on this information. Fix this by setting the sta->last_tx_rate in tx_status handling. There, look for last rates entry set by the driver, and use that as value for sta->last_tx_rate. Signed-off-by: Juuso Oikarinen Signed-off-by: John W.

Quoting from the changelog: This patch does it the same way, except that it also prioritize rx data processing, simply because tx routines *can* wait. This is causing an issue with us referencing already freed memory, because some skb's we transmit, we immediately receive back, such as those for reading the eeprom (*) and getting stats. What can happen because of the moving of the tx processing to after the rx processing is that when the tasklet first runs after doing a special skb tx (such as eeprom) we've already received the answer to it. Then the rx processing ends up calling p54_find_and_unlink_skb to find the matching tx skb for the just received special rx skb and frees the tx skb. Then after the processing of the rx skb answer, and thus freeing the tx skb, we go process the completed tx ring entires, and then dereference the free-ed skb, to see if it should free free-ed by p54p_check_tx_ring()."

If the dev_watchdog() timer fires during this time it is possible for a false tx timeout to occur. This patch moves the netif_carrier_off() so that it is called before the tx queues are stopped preventing the dev_watchdog timer from detecting false tx timeouts. The race is seen occosionally when FCoE or DCB settings are being configured or changed. Testing note, running ifconfig up/down will not reproduce this issue because dev_open/dev_close call dev_deactivate() and then dev_activate().

If bit 29 is set, MAC H/W can attempt to decrypt the received aggregate with WEP or TKIP, eventhough the received frame may be a CRC failed corrupted frame. If this bit is set, H/W obeys key type in keycache. If it is not set and if the key type in keycache is neither open nor AES, H/W forces key type to be open. But bit 29 should be set to 1 for AsyncFIFO feature to encrypt/decrypt the aggregate with WEP or TKIP.

This is due to a bug in the rts threshold check. if (len > tx->local->hw.wiphy->rts_threshold) { txrc.rts = rts = true; } Basically it is comparing an int (len) and a u32 (rts_threshold), and the variable len is assigned as: len = min_t(int, tx->skb->len + FCS_LEN, tx->local->hw.wiphy->frag_threshold); However, when frag_threshold is "-1", len is always "-1", which is 0xffffffff therefore rts is always set to true.

We should add backlog size and receive_queue size (aka rmem_alloc) to pace writers, and let user run without being slow down too much. Introduce a sk_rcvqueues_full() helper, to avoid taking socket lock in stress situations. Under huge stress from a multiqueue/RPS enabled NIC, a single flow udp receiver can now process ~200.000 pps (instead of ~100 pps before the patch) on a 8 core machine.

To do this the pci_dev pointer that was in the rings has been replaced with a device pointer, and as a result all references to [tr]x_ring->pdev have been replaced with [tr]x_ring->dev.

Miller" Date: Tue, 27 Apr 2010 16:49:58 -0700 Subject: Revert "bridge: Use hlist_for_each_entry_rcu() in br_multicast_add_router()" This reverts commit ff65e8275f6c96a5eda57493bd84c4555decf7b3. As explained by Stephen Hemminger, the traversal doesn't require RCU handling as we hold a lock. The list addition et al. calls, on the other hand, do. Signed-off-by: David S.

Substitute DPRINTK macro for e_ that uses netdev_ and dev_ similar to e1000e. - Convert printk to pr_ where applicable. - Use common #define pr_fmt for the driver. - Use dev_ for displaying text in parts of the driver where the interface name is not assigned (like e1000_param.c). - Better align test with the new macros.

Due to this the function cfcnfg_linkdestroy_rsp does nothing anymore. o Because disconnect may take down a connection before a connect response is received the function cfcnfg_linkup_rsp is checking if the client is still waiting for the response, if not a disconnect request is sent to the modem. o cfctrl is no longer keeping track of pending disconnect requests. o Added function cfctrl_cancel_req, which is used for deleting a pending connect request if disconnect is done before connect response is received. o Removed unused function cfctrl_insert_req2 o Added better handling of connect reject from modem.

This patch fixes command polling such that it is optimal for the fast commands, but also allows sleep for the longer ones.

After associated scans, the mac80211 does re-set the current channel, causing the join to occur. This would stop the hardware keep alive. To make the joins safer in this respect, this patch adds a join function that does the hardware-keep-alive magic along the join.

This is how they are implemented and what it says in the DebugFS documentation. DebugFS can not be compiled as a module. As a result, we only need to check for error pointers and particularly -ENODEV one time to know that DebugFS is enabled. This patch keeps the first check for error pointers and removes the rest. The other reason for this patch, is that it silences some Smatch warnings. Smatch sees the condition "(result != -ENODEV)" and assumes that it's possible for "result" to equal -ENODEV. If it were possible it would lead to an error pointer dereference. But since it's not, we can just remove the check. Signed-off-by: Dan Carpenter Signed-off-by: John W.

This patch introduces lock_sock_bh() and unlock_sock_bh() synchronization primitives, avoiding one atomic operation and backlog processing. skb_free_datagram_locked() uses them instead of full blown lock_sock()/release_sock(). skb is orphaned inside locked section for proper socket memory reclaim, and finally freed outside of it.

The comments in mac80211.h show there are actually three different, relevant variables, of which we are currently using two, both incorrectly. Fix this by making - ampdu_ack_len -> the number of ACKed frames (i.e. successes) - ampdu_ack_map -> the bitmap - ampdu_len -> the total number of frames sent (i.e., attempts) to match the header file (and verified with ath9k's usage) and updating Intel's RS code to match.

The MBM devices are instead identified by GUID. In order for cdc_ether to handle these devices the GUID in the MDLM descriptor is tested. All MBM devices currently handled by cdc_ether as well as future CDC Ethernet MBM devices can be identified by the GUID. This is the same solution used in Carl Nordbeck's mbm driver, http://kerneltrap.org/mailarchive/linux-usb/2008/11/17/4141384/thread I post this as RFC to get feedback on however cdc_ether is the correct place to do the binding, or if it should be done in a separate driver, e.g. zaurus.

RCU conversion is pretty much needed : 1) Add a new structure, called "struct socket_wq" to hold all fields that will need rcu_read_lock() protection (currently: a wait_queue_head_t and a struct fasync_struct pointer). [Future patch will add a list anchor for wakeup coalescing] 2) Attach one of such structure to each "struct socket" created in sock_alloc_inode(). 3) Respect RCU grace period when freeing a "struct socket_wq" 4) Change sk_sleep pointer in "struct sock" by sk_wq, pointer to "struct socket_wq" 5) Change sk_sleep() function to use new sk->sk_wq instead of sk->sk_sleep 6) Change sk_has_sleeper() to wq_has_sleeper() that must be used inside a rcu_read_lock() section. 7) Change all sk_has_sleeper() callers to : - Use rcu_read_lock() instead of read_lock(&sk->sk_callback_lock) - Use wq_has_sleeper() to eventually wakeup tasks. - Use rcu_read_unlock() instead of read_unlock(&sk->sk_callback_lock) 8) sock_wake_async() is modified to use rcu protection as well. 9) Exceptions : macvtap, drivers/net/tun.c, af_unix use integrated "struct socket_wq" instead of dynamically allocated ones. They dont need rcu freeing. Some cleanups or followups are probably needed, (possible sk_callback_lock conversion to a spinlock for example...). Signed-off-by: Eric Dumazet Signed-off-by: David S.

Tsirkin" Date: Wed, 17 Mar 2010 17:45:01 +0200 Subject: tun: add ioctl to modify vnet header size virtio added mergeable buffers mode where 2 bytes of extra info is put after vnet header but before actual data (tun does not need this data). In hindsight, it would have been better to add the new info *before* the packet: as it is, users need a lot of tricky code to skip the extra 2 bytes in the middle of the iovec, and in fact applications seem to get it wrong, and only work with specific iovec layout. The fact we might need to split iovec also means we might in theory overflow iovec max size. This patch adds a simpler way for applications to handle this, and future proofs the interface against further extensions, by making the size of the virtio net header configurable from userspace. As a result, tun driver will simply skip the extra 2 bytes on both input and output. Signed-off-by: Michael S. Tsirkin Acked-by: David S.

The original orinoco_usb patches had a boolean variable controlling whether spin_lock_bh was used, or irq based locking. This version provides wrappers for the lock functions and the drivers specify the functions pointers needed. This will introduce a performance penalty, but I'm not expecting it to be noticable.

Also, to debug mac80211 code itself, make hwsim "support" aggregation sessions. It will still just transfer the frame, but go through the setup and teardown handshakes.

I already tested it for bridge, bonding, bridge over bonding, and bonding over bridge. It looks fine now. To make bridge and bonding support netpoll, we need to adjust some netpoll generic code. This patch does the following things: 1) introduce two new priv_flags for struct net_device: IFF_IN_NETPOLL which identifies we are processing a netpoll; IFF_DISABLE_NETPOLL is used to disable netpoll support for a device at run-time; 2) introduce one new method for netdev_ops: ->ndo_netpoll_cleanup() is used to clean up netpoll when a device is removed. 3) introduce netpoll_poll_dev() which takes a struct net_device * parameter; export netpoll_send_skb() and netpoll_poll_dev() which will be used later; 4) hide a pointer to struct netpoll in struct netpoll_info, ditto. 5) introduce ->real_dev for struct netpoll. 6) introduce a new status NETDEV_BONDING_DESLAE, which is used to disable netconsole before releasing a slave, to avoid deadlocks.

The code in question is: * too big and complex (more than 550 SLOC.) This is enough to qualify for a new separate code file! * unbalanced quantity & quality over-engineered areas like: * xmit scheduling and queuing frames for multiple HT peers * redundant frame sorting are confronted by gaping holes: * accurate transmission feedback * firmware error-handling and device reset * HT rate control algorithm * error-prone Since its inclusion, hardly anything was done to fix any of the outlined flaws from the initial commit message. => This also indicates poor maintainability. * relies heavily on several spinlocks. As a result of this shortcomings, the code is slow and does not even support the most basic 11n requirement: HT station mode. Therefore, I request to purge my heap of **** from the kernel: "ar9170: implement transmit aggregation". The next item on the agenda is: (re-)start from scratch with an adequate design to accommodate the special requirements and features of the available frameworks and tools.

In order to improve this situation, first make the configuration APIs (cfg80211 and nl80211) aware of multi-channel operation -- we'll eventually need that in the future anyway. There's one userland API change and one API addition. The API change is that now SET_WIPHY must be called with virtual interface index rather than only wiphy index in order to take effect for that interface -- luckily all current users (hostapd) do that. For monitor interfaces, the old setting is preserved, but monitors are always slaved to other devices anyway so no guarantees. The second userland API change is the introduction of a per virtual interface SET_CHANNEL command, that hostapd should use going forward to make it easier to understand what's going on (it can automatically detect a kernel with this command). Other than mac80211, no existing cfg80211 drivers are affected by this change because they only allow a single virtual interface. mac80211, however, now needs to be aware that the channel settings are per interface now, and needs to disallow (for now) real multi-channel operation, which is another important part of this patch. One of the immediate benefits is that you can now start hostapd to operate on a hardware that already has a connection on another virtual interface, as long as you specify the same channel. Note that two things are left unhandled (this is an improvement -- not a complete fix): * different HT/no-HT modes currently you could start an HT AP and then connect to a non-HT network on the same channel which would configure the hardware for no HT; that can be fixed fairly easily * CSA An AP we're connected to on a virtual interface might indicate switching channels, and in that case we would follow it, regardless of how many other interfaces are operating; this requires more effort to fix but is pretty rare after all Signed-off-by: Johannes Berg Signed-off-by: John W.

This is clearly undesirable, since the new one might switch to no-HT while another one is operating in HT. Address this issue by keeping track of the HT mode per interface, and allowing only changes that are compatible, i.e. switching into HT40+ is not possible when another interface is in HT40-, in that case the second one needs to fall back to HT20. Also, to allow drivers to know what's going on, store the per-interface HT mode (channel type) in the virtual interface's bss_conf. Signed-off-by: Johannes Berg Signed-off-by: John W.

But transmission of beacons goes through the normal SKB queue maintained in hif_usb, leading to a situation where __skb_dequeue() in the TX completion handler goes kaput. Fix this by simply getting a beacon from mac80211 for every SWBA and free it in its completion routine. Signed-off-by: Sujith Signed-off-by: John W.

The reason for this is that the firmware JOIN command clears WPA(2) key material, and if done while associated to a WPA(2) secured AP, will render the data-path unusable. While the channel is not usually changed while associated (and currently we could not even support something like that), after performing a scan operation while associated, mac80211 will re-set the current channel to the driver. This caused our problem. Also, the mac80211 is assuming that the driver channel configuration remains persistent over periods of IDLE.

Given that we've had the ability to do emergency route cache rebuilds for awhile now, based on a statistical analysis of the various hash chain lengths in the cache, the use of the flush timer is somewhat redundant. This patch removes the rt_secret_interval sysctl, allowing us to rely solely on the statistical analysis mechanism to determine the need for route cache flushes.

The socket locks for that contexts are different, the user context uses a mutex(which can sleep) and the second one uses a spinlock_bh. That creates a race condition when we have interruptions on both contexts at the same time. The better way to solve this is to add a new spinlock to lock l2cap_ertm_send() and the vars it access. The other solution was to defer l2cap_ertm_send() with a workqueue, but we the sending process already has one defer on the hci layer. It's not a good idea add another one. The patch refactor the code to create l2cap_retransmit_frames(), then we encapulate the lock of l2cap_ertm_send() for some call. It also changes l2cap_retransmit_frame() to l2cap_retransmit_one_frame() to avoid confusion Signed-off-by: Gustavo F.

Padovan" Date: Tue, 4 May 2010 23:16:01 -0300 Subject: Bluetooth: Fix spec error in the RemoteBusy Logic On the receipt of an RR(P=1) under RemoteBusy set to TRUE(on the RECV state table) we have to call sendIorRRorRNR(F=1) and just after set RemoteBusy to False. This leads to a freeze in the sending process since it's not allowed send data with RemoteBusy set to true and no one call SendPending-I-Frames after set RemoteBusy to false(The last action for that event). Actually sendIorRRorRNR() calls SendPending-I-Frames but at that moment RemoteBusy is still True and we cannot send any frame, after, no one calls SendPending-I-Frames again and the sending process stops. The solution here is to set RemoteBusy to false inside SendPending-I-Frames just before call SendPending-I-Frames. That will make SendPending-I-Frames able to send frames. This solution is similar to what RR(P=0)(F=0) on the RECV table and RR(P=1) on the SREJ_SENT table do.

All of the driver's kick_tx_queue callback functions treat the TX queue for beacons in a special manner. Clean this up by integrating the kicking of the beacon queue into the write_beacon callback function, and let the generic code no longer call the kick_tx_queue callback function when updating the beacon.

That leads to a bug with injection -- it is currently not possible to inject frames when the only virtual interface is a monitor, because in that the required broadcast station is missing. Additionally, allocating and deallocating the broadcast station's LQ all the time is wasteful, and the code to support this is fairly complex. So this changes completely the way we manage the broadcast station. Rather than manage it along with any interface, we now allocate it when we bring the device up, and remove it again when we bring the device down. When we bring the device up, we don't immediately program the broadcast station into it, instead we just mark it active and rely on the next restore cycle to upload it to the device. This works because an unassociated RXON is always required at least once to set up device parameters, which implies a reprogramming of stations into the device. As we now manage all stations properly, there no longer is a need for forcing a clearing of them via iwl_clear_ucode_stations(), which can become a lot simpler.

A consequence of that is that the driver will know that it is not communicating on HT anymore, but the rate scaling table is still under the impression it is operating in HT. Any time after driver has been notified channel is not HT anymore there will thus be a firmware SYSASSERT when the current active LQ command is sent. A workaround for this issue is to not send a LQ command in the short time between being notified channel is not HT anymore and rate scaling table being updated.

Userspace multicast routing daemons can bind to a specific table instance by issuing a setsockopt call using a new option MRT6_TABLE. The table number is stored in the raw socket data and affects all following ip6mr setsockopt(), getsockopt() and ioctl() calls. By default, a single table (RT6_TABLE_DFLT) is created with a default routing rule pointing to it. Newly created pim6reg devices have the table number appended ("pim6regX"), with the exception of devices created in the default table, which are named just "pim6reg" for compatibility reasons. Packets are directed to a specific table instance using routing rules, similar to how regular routing rules work. Currently iif, oif and mark are supported as keys, source and destination addresses could be supported additionally. Example usage: - bind pimd/xorp/... to a specific table: uint32_t table = 123; setsockopt(fd, SOL_IPV6, MRT6_TABLE, &table, sizeof(table)); - create routing rules directing packets to the new table: # ip -6 mrule add iif eth0 lookup 123 # ip -6 mrule add oif eth0 lookup 123 Signed-off-by: Patrick McHardy diff --git a/include/linux/ipv6.h b/include/linux/ipv6.h index 0e26903..99e1ab7 100644 --- a/include/linux/ipv6.h +++ b/include/linux/ipv6.h @@ -383,6 +383,7 @@ struct raw6_sock { __u32 checksum; /* perform checksum */ __u32 offset; /* checksum offset */ struct icmp6_filter filter; + __u32 ip6mr_table; /* ipv6_pinfo has to be the last member of raw6_sock, see inet6_sk_generic */ struct ipv6_pinfo inet6; }; diff --git a/include/linux/mroute6.h b/include/linux/mroute6.h index 0370dd4..6091ab7 100644 --- a/include/linux/mroute6.h +++ b/include/linux/mroute6.h @@ -24,7 +24,8 @@ #define MRT6_DEL_MFC (MRT6_BASE+5) /* Delete a multicast forwarding entry */ #define MRT6_VERSION (MRT6_BASE+6) /* Get the kernel multicast version */ #define MRT6_ASSERT (MRT6_BASE+7) /* Activate PIM assert mode */ -#define MRT6_PIM (MRT6_BASE+8) /* enable PIM code */ +#define MRT6_PIM (MRT6_BASE+8) /* enable PIM code */ +#define MRT6_TABLE (MRT6_BASE+9) /* Specify mroute table ID */ #define SIOCGETMIFCNT_IN6 SIOCPROTOPRIVATE /* IP protocol privates */ #define SIOCGETSGCNT_IN6 (SIOCPROTOPRIVATE+1) @@ -229,11 +230,17 @@ extern int ip6mr_get_route(struct net *net, struct sk_buff *skb, struct rtmsg *rtm, int nowait); #ifdef CONFIG_IPV6_MROUTE -extern struct sock *mroute6_socket(struct net *net); +extern struct sock *mroute6_socket(struct net *net, struct sk_buff *skb); extern int ip6mr_sk_done(struct sock *sk); #else -static inline struct sock *mroute6_socket(struct net *net) { return NULL; } -static inline int ip6mr_sk_done(struct sock *sk) { return 0; } +static inline struct sock *mroute6_socket(struct net *net, struct sk_buff *skb) +{ + return NULL; +} +static inline int ip6mr_sk_done(struct sock *sk) +{ + return 0; +} #endif #endif diff --git a/include/linux/rtnetlink.h b/include/linux/rtnetlink.h index 5a42c36..fbc8cb0 100644 --- a/include/linux/rtnetlink.h +++ b/include/linux/rtnetlink.h @@ -11,7 +11,8 @@ * families, values above 128 may be used arbitrarily. */ #define RTNL_FAMILY_IPMR 128 -#define RTNL_FAMILY_MAX 128 +#define RTNL_FAMILY_IP6MR 129 +#define RTNL_FAMILY_MAX 129 /**** * Routing/neighbour discovery messages. diff --git a/include/net/netns/ipv6.h b/include/net/netns/ipv6.h index 4e2780e..81abfcb 100644 --- a/include/net/netns/ipv6.h +++ b/include/net/netns/ipv6.h @@ -59,7 +59,12 @@ struct netns_ipv6 { struct sock *tcp_sk; struct sock *igmp_sk; #ifdef CONFIG_IPV6_MROUTE +#ifndef CONFIG_IPV6_MROUTE_MULTIPLE_TABLES struct mr6_table *mrt6; +#else + struct list_head mr6_tables; + struct fib_rules_ops *mr6_rules_ops; +#endif #endif }; #endif diff --git a/net/ipv6/Kconfig b/net/ipv6/Kconfig index a578096..36d7437 100644 --- a/net/ipv6/Kconfig +++ b/net/ipv6/Kconfig @@ -229,6 +229,20 @@ config IPV6_MROUTE Experimental support for IPv6 multicast forwarding.

Introduce a new netlink interface to dump multicast routes from all tables, similar to the netlink interface for regular routes.

Also, instead of dropping them immediately though move the check *after* we check for all sort of frame errors. This should enable us to discard these frames if the hardware picks other bogus items first. Lets see if we still get those jumbo counters increasing still with this. Jumbo frames would happen if we tell hardware we can support a small 802.11 chunks of DMA'd frame, hardware would split RX'd frames into parts and we'd have to reconstruct them in software. This is done with USB due to the bulk size but with ath5k we already provide a good limit to hardware and this should not be happening. This is reported quite often and if it fills the logs then this needs to be addressed and to avoid spurious reports. Cc: stable@kernel.org Signed-off-by: Luis R. Rodriguez Signed-off-by: John W.

Therefore, on SDIO interface, the reset event should be still detected and handled by dev_reset_handle(). Problem description: Whenever a reboot barker is received during operational mode (i2400m->boot_mode == 0), dev_reset_handle() is invoked to handle that function reset event. dev_reset_handle() then sets the flag i2400m->boot_mode to 1 indicating the device is back to bootmode before proceeding to dev_stop() and dev_start(). If dev_start() returns failure, a bus reset is triggered by dev_reset_handle(). The flag i2400m->boot_mode then remains 1 when the second reboot barker arrives. However the interrupt service routine i2400ms_rx() instead of invoking dev_reset_handle() to handle that reset event, it filters out that boot event to bootmode because it sees the flag i2400m->boot_mode equal to 1. The fix: Maintain the flag i2400m->boot_mode within dev_reset_handle() and set the flag i2400m->boot_mode to 1 when entering dev_reset_handle(). It remains 1 until the dev_reset_handle() issues a bus reset. ie: the bus reset is taking place just like it happens for the first time during operational mode. To denote the actual device state and the state we expect, a flag i2400m->alive is introduced in addition to the existing flag i2400m->updown. It's maintained with the same way for i2400m->updown but instead of reflecting the actual state like i2400m->updown does, i2400m->alive maintains the state we expect. i2400m->alive is set 1 just like whenever i2400m->updown is set 1. Yet i2400m->alive remains 1 since we expect the device to be up all the time until the driver is removed. See the doc for @alive in i2400m.h. An enumeration I2400M_BUS_RESET_RETRIES is added to define the maximum number of bus resets that a device reboot can retry. A counter i2400m->bus_reset_retries is added to track how many bus resets have been retried in one device reboot. If I2400M_BUS_RESET_RETRIES bus resets were retried in this boot, we give up any further retrying so the device would enter low power state. The counter i2400m->bus_reset_retries is incremented whenever dev_reset_handle() is issuing a bus reset and is cleared to 0 when dev_start() is successfully done, ie: a successful reboot.

The intention is to bring back the device to some known state whenever TX sees -110 (-ETIMEOUT) on copying the data to the HW FIFO. The TX failure could mean a device bus stuck or function stuck, so the current error recovery implementation is to trigger a bus reset and expect this can bring back the device. Since the TX work is done in a thread context, there may be a queue of TX works already that all hit the -ETIMEOUT error condition because the device has somewhat stuck already. We don't want any consecutive bus resets simply because multiple TX works in the queue all hit the same device erratum, the flag "error_recovery" is introduced to denote if we are ready for taking any error recovery.

When a device reset happens and the TX FIFO is released/re-allocated, a new block of memory may be allocated for the TX FIFO, therefore tx_msg should be cleared so that no any TX threads (tx_worker, tx) would access to the out-of-date addresses. Also, the TX threads use tx_in and tx_out to decide where to put the new host-to-device messages and from where to copy them to the device HW FIFO, these indices have to be cleared so after the TX FIFO is re-allocated during the reset, the indices both refer to the head of the FIFO, ie. a new start. The same rational applies to tx_msg_size and tx_sequence. To protect the indices from being accessed by multiple threads simultaneously, the lock tx_lock has to be obtained before the initializations and released afterwards.

This means that we can end up doing the work for an association request item when (for whatever reason) we receive another frame type, for example a probe response. Processing the wrong type of frame will lead to completely invalid data being processed, and will lead to various problems like thinking the association was successful even if the AP never sent an assocation response. Fix this by making each processing function check that it is invoked for the right work struct type only and continue processing otherwise (and drop frames that we didn't expect). This bug was uncovered during the debugging for https://bugzilla.kernel.org/show_bug.cgi?id=15862 but doesn't seem to be the cause for any of the various problems reported there.

The handling of tx descriptors for beacons can be simplified by updating write_tx_desc implementations of each driver to write directly to the queue entry descriptor instead of to a provided memory area. This is also a preparation for further clean ups where descriptors are properly reserved in the skb instead of fiddling with the skb data pointer.

The ARC subsystem is currently only available on 80003es2lan and 82573 parts supported by the driver. A new flag, has_fwsm, is introduced to be used when checking if manageability is enabled but only on parts that acutally have an FWSM register. While the above parts have an FWSM register, there are other parts that have FWSM but do not have support for the ARC subsystem, namely 82571/2 and ICHx/PCH. And then there are parts that have manageability, but do not have either FWSM register or support for the ARC subsystem - these are 82574 and 82583. For 80003es2lan, 82571/2/3 and ICH/PCH parts, this patch makes no functional changes, it only corrects the usage of the manageability flags. For 82574 and 82583, it fixes the incorrect accesses of the non-existent FWSM register and ARC subsystem as well as corrects the check for management pass-through.

However, e1000_lan_init_done_ich8lan() had already been called in one of the two places where PHY reset occurs for ICHx/PCHx parts, which caused the second call to busy-wait for 150 msec because the LAN_INIT_DONE bit had already been checked and cleared. ii) Cleanup the two separate PHY reset code paths, i.e. the full-chip reset in e1000_reset_hw_ich8lan() and the PHY-only reset in e1000_phy_hw_reset_ich8lan(). There was duplicate code in both paths to be performed post-reset that are now combined into one new function - e1000_post_phy_reset_ich8lan(). This cleanup also included moving the clearing of the PHY Reset Asserted bit in the STATUS register (now done for all ICH/PCH parts) and the check for the indication from h/w that basic configuration has completed back to where it previously was in e1000_get_cfg_done_ich8lan(). iii) Corrected a few comments Signed-off-by: Bruce Allan Signed-off-by: Jeff Kirsher Signed-off-by: David S.

As well as being unable to remove interfaces after this occurs (because userspace tools don't recognise the new name, and the kernel won't recognise the old name), adding another interface with the old name to the bridge will cause an error trying to create the sysfs link.

As we are about to add another integer handling proc function a little bit of cleanup is in order: add a few helper functions to improve code readability and decrease code duplication. In the process a bug is also fixed: if the user specifies a number with more then 20 digits it will be interpreted as two integers (e.g. 10000...13 will be interpreted as 100.... and 13). Behavior for EFAULT handling was changed as well. Previous to this patch, when an EFAULT error occurred in the middle of a write operation, although some of the elements were set, that was not acknowledged to the user (by shorting the write and returning the number of bytes accepted). EFAULT is now treated just like any other errors by acknowledging the amount of bytes accepted. Signed-off-by: Octavian Purdila Signed-off-by: WANG Cong Cc: Eric W. Biederman Signed-off-by: David S.

If netif_receive_skb() is used, its deferred after RPS dispatch. If netif_rx() is used, its done before RPS dispatch. This can give strange tcpdump timestamps results. I think timestamping should be done as soon as possible in the receive path, to get meaningful values (ie timestamps taken at the time packet was delivered by NIC driver to our stack), even if NAPI already can defer timestamping a bit (RPS can help to reduce the gap) Tom Herbert prefer to sample timestamps after RPS dispatch. In case sampling is expensive (HPET/acpi_pm on x86), this makes sense. Let admins switch from one mode to another, using a new sysctl, /proc/sys/net/core/netdev_tstamp_prequeue Its default value (1), means timestamps are taken as soon as possible, before backlog queueing, giving accurate timestamps. Setting a 0 value permits to sample timestamps when processing backlog, after RPS dispatch, to lower the load of the pre-RPS cpu. Signed-off-by: Eric Dumazet Signed-off-by: David S.

Change _skb_dst to _skb_refdst to make sure all uses are catched. skb_dst() returns the dst, regardless of noref bit set or not, but with a lockdep check to make sure a noref dst is not given if current user is not rcu protected. New skb_dst_set_noref() helper to set an notrefcounted dst on a skb. (with lockdep check) skb_dst_drop() drops a reference only if skb dst was refcounted. skb_dst_force() helper is used to force a refcount on dst, when skb is queued and not anymore RCU protected. Use skb_dst_force() in __sk_add_backlog(), __dev_xmit_skb() if !IFF_XMIT_DST_RELEASE or skb enqueued on qdisc queue, in sock_queue_rcv_skb(), in __nf_queue(). Use skb_dst_force() in dev_requeue_skb(). Note: dst_use_noref() still dirties dst, we might transform it later to do one dirtying per jiffies. Signed-off-by: Eric Dumazet Signed-off-by: David S.

prevent timeout. Based on original patch from Stanislaw Gruszka . Using netif_carrier_off() is better than updating all the ->trans_start on all the tx queues. netif_carrier_off() needs to be called after bnx2_disable_int_sync() to guarantee no race conditions with the serdes timers that can modify the carrier state. If the chip or phy is reset, carrier will turn back on when we get the link interrupt. If there is no reset, we need to turn carrier back on in bnx2_netif_start(). Again, the phy_lock prevents race conditions with the serdes timers. Signed-off-by: Michael Chan Signed-off-by: Matt Carlson Signed-off-by: David S.

Some stacks (old linux for example) try to negotiate MD5+SACK+TSTAMP sessions, but since 40 bytes of tcp options space are not enough to store all the bits needed, we chose to disable timestamps in this case. We send a SYN-ACK _without_ timestamp option, but socket has timestamps enabled and all further outgoing messages contain a TS block, all with the initial timestamp of the remote peer. Fix is to really disable timestamps option for the whole session. Reported-by: Bijay Singh Signed-off-by: Eric Dumazet Signed-off-by: David S.

Extends netlink socket RTM_SETLINK/ RTM_GETLINK with two new sub msgs called IFLA_VF_PORTS and IFLA_PORT_SELF (added to end of IFLA_cmd list). These are both nested atrtibutes using this layout: [IFLA_NUM_VF] [IFLA_VF_PORTS] [IFLA_VF_PORT] [IFLA_PORT_*], ... [IFLA_VF_PORT] [IFLA_PORT_*], ... ... [IFLA_PORT_SELF] [IFLA_PORT_*], ... These attributes are design to be set and get symmetrically. VF_PORTS is a list of VF_PORTs, one for each VF, when dealing with an SR-IOV device. PORT_SELF is for the PF of the SR-IOV device, in case it wants to also have a port-profile, or for the case where the VF==PF, like in enic patch 2/2 of this patch set. A port-profile is used to configure/enable the external switch virtual port backing the netdev interface, not to configure the host-facing side of the netdev. A port-profile is an identifier known to the switch. How port- profiles are installed on the switch or how available port-profiles are made know to the host is outside the scope of this patch. There are two types of port-profiles specs in the netlink msg. The first spec is for 802.1Qbg (pre-)standard, VDP protocol. The second spec is for devices that run a similar protocol as VDP but in firmware, thus hiding the protocol details. In either case, the specs have much in common and makes sense to define the netlink msg as the union of the two specs. For example, both specs have a notition of associating/deassociating a port-profile. And both specs require some information from the hypervisor manager, such as client port instance ID. The general flow is the port-profile is applied to a host netdev interface using RTM_SETLINK, the receiver of the RTM_SETLINK msg communicates with the switch, and the switch virtual port backing the host netdev interface is configured/enabled based on the settings defined by the port-profile. What those settings comprise, and how those settings are managed is again outside the scope of this patch, since this patch only deals with the first step in the flow.

Enic dynamic devices are just like normal enic eth devices except dynamic enics require an extra configuration step to assign a port-profile identifier to the interface before the interface is useable. Once a port-profile is assigned, link comes up on the interface and is ready for I/O. The port-profile is used to configure the network port assigned to the interface. The network port configuration includes VLAN membership, QoS policies, and port security settings typical of a data center network. A dynamic enic initially has a zero-mac address. Before a port-profile is assigned, a valid non-zero unicast mac address should be assign to the dynamic enic interface.

The SJA1000 data sheet, 6.4.4 COMMAND REGISTER (CMR) states: "Between two commands at least one internal clock cycle is needed in order to proceed. The internal clock is half of the external oscillator frequency." On SMP systems the current implementation leads to a write stall in the tx-path, which can be solved by adding some general locking and some time to settle the write_reg() operation for the command register. Thanks to Klaus Hitschler for the original fix and detailed problem description. This patch applies on net-2.6 and (with some offsets) on net-next-2.6 .
