2011-02-05genirq: Add missing status flags to modification maskThomas Gleixner
The mask which filters out the valid bits which can be set via irq_modify_status() is missing IRQ_NO_BALANCING, which breaks UV. Add IRQ_PER_CPU as well to avoid another one line patch for 39. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2011-02-04inetpeer: Move ICMP rate limiting state into inet_peer entries.David S. Miller
Like metrics, the ICMP rate limiting bits are cached state about a destination. So move it into the inet_peer entries. If an inet_peer cannot be bound (the reason is memory allocation failure or similar), the policy is to allow. Signed-off-by: David S. Miller <davem@davemloft.net>

2011-02-03mac80211: Add testing functionality for TKIPJouni Malinen
TKIP countermeasures depend on devices being able to detect Michael MIC failures on received frames and for stations to report errors to the AP. In order to test that behavior, it is useful to be able to send out TKIP frames with incorrect Michael MIC. This testing behavior has minimal effect on the TX path, so it can be added to mac80211 for convenient use. The interface for using this functionality is a file in mac80211 netdev debugfs (tkip_mic_test). Writing a MAC address to the file makes mac80211 generate a dummy data frame that will be sent out using invalid Michael MIC value. In AP mode, the address needs to be for one of the associated stations or ff:ff:ff:ff:ff:ff to use a broadcast frame. In station mode, the address can be anything, e.g., the current BSSID. It should be noted that this functionality works correctly only when associated and using TKIP.

2011-02-03mac80211: add HW flag for disabling auto link-PS in AP modeArik Nemtsov
When operating in AP mode the wl1271 hardware filters out null-data packets as well as management packets. This makes it impossible for mac80211 to monitor the PS mode by using the PM bit of incoming frames. Implement a HW flag to indicate that mac80211 should ignore the PM bit. In addition, expose ieee80211_sta_ps_transition() to make low-level drivers capable of controlling PS-mode. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: John W.

2011-02-03tracing: Replace syscall_meta_data struct array with pointer arraySteven Rostedt
Currently the syscall_meta structures for the syscall tracepoints are placed in the __syscall_metadata section, and at link time, the linker makes one large array of all these syscall metadata structures. On boot up, this array is read (much like the initcall sections) and the syscall data is processed. The problem is that there is no guarantee that gcc will place complex structures nicely together in an array format. Two structures in the same file may be placed awkwardly, because gcc has no clue that they are suppose to be in an array. A hack was used previous to force the alignment to 4, to pack the structures together. But this caused alignment issues with other architectures (sparc). Instead of packing the structures into an array, the structures' addresses are now put into the __syscall_metadata section. As pointers are always the natural alignment, gcc should always pack them tightly together (otherwise initcall, extable, etc would also fail). By having the pointers to the structures in the section, we can still iterate the trace_events without causing unnecessary alignment problems with other architectures, or depending on the current behaviour of gcc that will likely change in the future just to tick us kernel developers off a little more. The __syscall_metadata section is also moved into the .init.data section as it is now only needed at boot up. Suggested-by: David Miller <davem@davemloft.net> Acked-by: David S.

2011-02-03tracepoints: Fix section alignment using pointer arrayMathieu Desnoyers
Make the tracepoints more robust, making them solid enough to handle compiler changes by not relying on anything based on compiler-specific behavior with respect to structure alignment. Implement an approach proposed by David Miller: use an array of const pointers to refer to the individual structures, and export this pointer array through the linker script rather than the structures per se. It will consume 32 extra bytes per tracepoint (24 for structure padding and 8 for the pointers), but are less likely to break due to compiler changes. History: commit 7e066fb8 tracepoints: add DECLARE_TRACE() and DEFINE_TRACE() added the aligned(32) type and variable attribute to the tracepoint structures to deal with gcc happily aligning statically defined structures on 32-byte multiples. One attempt was to use a 8-byte alignment for tracepoint structures by applying both the variable and type attribute to tracepoint structures definitions and declarations. It worked fine with gcc 4.5.1, but broke with gcc 4.4.4 and 4.4.5. The reason is that the "aligned" attribute only specify the _minimum_ alignment for a structure, leaving both the compiler and the linker free to align on larger multiples. Because tracepoint.c expects the structures to be placed as an array within each section, up-alignment cause NULL-pointer exceptions due to the extra unexpected padding.

CHOKe ("CHOose and Kill" or "CHOose and Keep") is an alternative packet scheduler based on the Random Exponential Drop (RED) algorithm. The core idea is: For every packet arrival: Calculate Qave if (Qave < minth) Queue the new packet else Select randomly a packet from the queue if (both packets from same flow) then Drop both the packets else if (Qave > maxth) Drop packet else Admit packet with proability p (same as RED) See also: Rong Pan, Balaji Prabhakar, Konstantinos Psounis, "CHOKe: a stateless active queue management scheme for approximating fair bandwidth allocation", Proceeding of INFOCOM'2000, March 2000.

2011-02-03memcg: prevent endless loop when charging huge pages to near-limit groupJohannes Weiner
If reclaim after a failed charging was unsuccessful, the limits are checked again, just in case they settled by means of other tasks. This is all fine as long as every charge is of size PAGE_SIZE, because in that case, being below the limit means having at least PAGE_SIZE bytes available. But with transparent huge pages, we may end up in an endless loop where charging and reclaim fail, but we keep going because the limits are not yet exceeded, although not allowing for a huge page. Fix this up by explicitely checking for enough room, not just whether we are within limits.

For the following rule: iptables -I PREROUTING -t raw -j CT --ctevents assured The event delivered looks like the following: [UPDATE] tcp 6 src=192.168.0.2 dst=192.168.1.2 sport=37041 dport=80 src=192.168.1.2 dst=192.168.1.100 sport=80 dport=37041 [ASSURED] Note that the TCP protocol state is not included. For that reason the CT event filtering is not very useful for conntrackd. To resolve this issue, instead of conditionally setting the CT events bits based on the ctmask, we always set them and perform the filtering in the late stage, just before the delivery. Thus, the event delivered looks like the following: [UPDATE] tcp 6 432000 ESTABLISHED src=192.168.0.2 dst=192.168.1.2 sport=37041 dport=80 src=192.168.1.2 dst=192.168.1.100 sport=80 dport=37041 [ASSURED] Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: Patrick McHardy <kaber@trash.net>

2011-02-01netfilter: ipset: list:set set type supportJozsef Kadlecsik
The module implements the list:set type support in two flavours: without and with timeout. The sets has two sides: for the userspace, they store the names of other (non list:set type of) sets: one can add, delete and test set names. For the kernel, it forms an ordered union of the member sets: the members sets are tried in order when elements are added, deleted and tested and the process stops at the first success.

2011-02-01netfilter: ipset: hash:ip set type supportJozsef Kadlecsik
The module implements the hash:ip type support in four flavours: for IPv4 or IPv6, both without and with timeout support. All the hash types are based on the "array hash" or ahash structure and functions as a good compromise between minimal memory footprint and speed. The hashing uses arrays to resolve clashes. The hash table is resized (doubled) when searching becomes too long. Resizing can be triggered by userspace add commands only and those are serialized by the nfnl mutex. During resizing the set is read-locked, so the only possible concurrent operations are the kernel side readers. Those are protected by RCU locking. Because of the four flavours and the other hash types, the functions are implemented in general forms in the ip_set_ahash.h header file and the real functions are generated before compiling by macro expansion. Thus the dereferencing of low-level functions and void pointer arguments could be avoided: the low-level functions are inlined, the function arguments are pointers of type-specific structures.

2011-02-01netfilter: ipset: IP set core supportJozsef Kadlecsik
The patch adds the IP set core support to the kernel. The IP set core implements a netlink (nfnetlink) based protocol by which one can create, destroy, flush, rename, swap, list, save, restore sets, and add, delete, test elements from userspace. For simplicity (and backward compatibilty and for not to force ip(6)tables to be linked with a netlink library) reasons a small getsockopt-based protocol is also kept in order to communicate with the ip(6)tables match and target. The netlink protocol passes all u16, etc values in network order with NLA_F_NET_BYTEORDER flag. The protocol enforces the proper use of the NLA_F_NESTED and NLA_F_NET_BYTEORDER flags. For other kernel subsystems (netfilter match and target) the API contains the functions to add, delete and test elements in sets and the required calls to get/put refereces to the sets before those operations can be performed. The set types (which are implemented in independent modules) are stored in a simple RCU protected list. A set type may have variants: for example without timeout or with timeout support, for IPv4 or for IPv6. The sets (i.e. the pointers to the sets) are stored in an array. The sets are identified by their index in the array, which makes possible easy and fast swapping of sets. The array is protected indirectly by the nfnl mutex from nfnetlink. The content of the sets are protected by the rwlock of the set. There are functional differences between the add/del/test functions for the kernel and userspace: - kernel add/del/test: works on the current packet (i.e. one element) - kernel test: may trigger an "add" operation in order to fill out unspecified parts of the element from the packet (like MAC address) - userspace add/del: works on the netlink message and thus possibly on multiple elements from the IPSET_ATTR_ADT container attribute. - userspace add: may trigger resizing of a set Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu> Signed-off-by: Patrick McHardy <kaber@trash.net>

2011-02-01ipv4: Consolidate all default route selection implementations.David S. Miller
Both fib_trie and fib_hash have a local implementation of fib_table_select_default(). This is completely unnecessary code duplication. Since we now remember the fib_table and the head of the fib alias list of the default route, we can implement one single generic version of this routine. Looking at the fib_hash implementation you may get the impression that it's possible for there to be multiple top-level routes in the table for the default route. The truth is, it isn't, the insert code will only allow one entry to exist in the zero prefix hash table, because all keys evaluate to zero and all keys in a hash table must be unique.

2011-01-31drm/i915: Suppress spurious vblank interruptsChris Wilson
Hugh Dickins found that characters in xterm were going missing and oft delayed. Being the curious type, he managed to associate this with the new high-precision vblank patches; disabling these he found, restored the orderliness of his characters. The oddness begins when one realised that Hugh was not using vblanks at all on his system (fvwm and some xterms). Instead, all he had to go on were warning of a pipe underrun, curiously enough at around 60Hz. He poked and found that in addition to the underrun warning, the hardware was flagging the start of a new frame, a vblank, which in turn was kicking off the pending vblank processing code. There is little we can do for the underruns on Hugh's machine, a Crestline [965GM], which must have its FIFO watermarks set to 8. However, we do not need to process the vblank if we know that they are disabled... Reported-by: Hugh Dickins <hughd@google.com> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-01-30net: Add compat ioctl support for the ipv4 multicast ioctl SIOCGETSGCNTEric W. Biederman
SIOCGETSGCNT is not a unique ioctl value as it it maps tio SIOCPROTOPRIVATE +1, which unfortunately means the existing infrastructure for compat networking ioctls is insufficient. A trivial compact ioctl implementation would conflict with: SIOCAX25ADDUID SIOCAIPXPRISLT SIOCGETSGCNT_IN6 SIOCGETSGCNT SIOCRSSCAUSE SIOCX25SSUBSCRIP SIOCX25SDTEFACILITIES To make this work I have updated the compat_ioctl decode path to mirror the the normal ioctl decode path. I have added an ipv4 inet_compat_ioctl function so that I can have ipv4 specific compat ioctls. I have added a compat_ioctl function into struct proto so I can break out ioctls by which kind of ip socket I am using. I have added a compat_raw_ioctl function because SIOCGETSGCNT only works on raw sockets. I have added a ipmr_compat_ioctl that mirrors the normal ipmr_ioctl. This was necessary because unfortunately the struct layout for the SIOCGETSGCNT has unsigned longs in it so changes between 32bit and 64bit kernels. This change was sufficient to run a 32bit ip multicast routing daemon on a 64bit kernel. Reported-by: Bill Fenner <fenner@aristanetworks.com> Signed-off-by: Eric W.
