2014-12-22in6: fix conflict with glibcstephen hemminger
Resolve conflicts between glibc definition of IPV6 socket options and those defined in Linux headers. Looks like earlier efforts to solve this did not cover all the definitions. It resolves warnings during iproute2 build. Please consider for stable as well.

2014-12-22virtio_net: Fix napi poll list corruptionHerbert Xu
The commit d75b1ade567ffab085e8adbbdacf0092d10cd09c (net: less interrupt masking in NAPI) breaks virtio_net in an insidious way. It is now required that if the entire budget is consumed when poll returns, the napi poll_list must remain empty. However, like some other drivers virtio_net tries to do a last-ditch check and if there is more work it will call napi_schedule and then immediately process some of this new work. Should the entire budget be consumed while processing such new work then we will violate the new caller contract. This patch fixes this by not touching any work when we reschedule in virtio_net. The worst part of this bug is that the list corruption causes other napi users to be moved off-list. In my case I was chasing a stall in IPsec (IPsec uses netif_rx) and I only belatedly realised that it was virtio_net which caused the stall even though the virtio_net poll was still functioning perfectly after IPsec stalled.

2014-12-22stmmac: Don't init ptp again when resume from suspend/hibernationHuacai Chen
Both stmmac_open() and stmmac_resume() call stmmac_hw_setup(), and stmmac_hw_setup() call stmmac_init_ptp() unconditionally. However, only stmmac_release() calls stmmac_release_ptp(). Since stmmac_suspend() doesn't call stmmac_release_ptp(), stmmac_resume() also needn't call stmmac_init_ptp(). This patch also fix a "scheduling while atomic" problem when resume from suspend/hibernation. Because stmmac_init_ptp() will trigger scheduling while stmmac_resume() hold a spinlock. Callgraph of "scheduling while atomic": stmmac_resume() --> stmmac_hw_setup() --> stmmac_init_ptp() --> stmmac_ptp_register() --> ptp_clock_register() --> device_create() --> device_create_groups_vargs() --> device_add() --> devtmpfs_create_node() --> wait_for_common() --> schedule_timeout() --> __schedule() Signed-off-by: Huacai Chen <chenhc@lemote.com> Signed-off-by: David S.

2014-12-22packet: Fixed TPACKET V3 to signal poll when block is closed rather than ↵Dan Collins
every packet Make TPACKET_V3 signal poll when block is closed rather than for every packet. Side effect is that poll will be signaled when block retire timer expires which didn't previously happen. Issue was visible when sending packets at a very low frequency such that all blocks are retired before packets are received by TPACKET_V3. This caused avoidable packet loss. The fix ensures that the signal is sent when blocks are closed which covers the normal path where the block is filled as well as the path where the timer expires. The case where a block is filled without moving to the next block (ie. all blocks are full) will still cause poll to be signaled.

2014-12-22cifs: make new inode cache when file type is differentNakajima Akira
In spite of different file type, if file is same name and same inode number, old inode cache is used. This causes that you can not cd directory, can not cat SymbolicLink. So this patch is that if file type is different, return error. Reproducible sample : 1. create file 'a' at cifs client. 2. repeat rm and mkdir 'a' 4 times at server, then direcotry 'a' having same inode number is created. (Repeat 4 times, then same inode number is recycled.) (When server is under RHEL 6.6, 1 time is O.K. Always same inode number is recycled.) 3. ls -li at client, then you can not cd directory, can not remove directory. SymbolicLink has same problem.

2014-12-22audit: correctly record file names with different path name typesPaul Moore
There is a problem with the audit system when multiple audit records are created for the same path, each with a different path name type. The root cause of the problem is in __audit_inode() when an exact match (both the path name and path name type) is not found for a path name record; the existing code creates a new path name record, but it never sets the path name in this record, leaving it NULL. This patch corrects this problem by assigning the path name to these newly created records. There are many ways to reproduce this problem, but one of the easiest is the following (assuming auditd is running): # mkdir /root/tmp/test # touch /root/tmp/test/567 # auditctl -a always,exit -F dir=/root/tmp/test # touch /root/tmp/test/567 Afterwards, or while the commands above are running, check the audit log and pay special attention to the PATH records. A faulty kernel will display something like the following for the file creation: type=SYSCALL msg=audit(1416957442.025:93): arch=c000003e syscall=2 success=yes exit=3 ... comm="touch" exe="/usr/bin/touch" type=CWD msg=audit(1416957442.025:93): cwd="/root/tmp" type=PATH msg=audit(1416957442.025:93): item=0 name="test/" inode=401409 ... nametype=PARENT type=PATH msg=audit(1416957442.025:93): item=1 name=(null) inode=393804 ... nametype=NORMAL type=PATH msg=audit(1416957442.025:93): item=2 name=(null) inode=393804 ... nametype=NORMAL While a patched kernel will show the following: type=SYSCALL msg=audit(1416955786.566:89): arch=c000003e syscall=2 success=yes exit=3 ... comm="touch" exe="/usr/bin/touch" type=CWD msg=audit(1416955786.566:89): cwd="/root/tmp" type=PATH msg=audit(1416955786.566:89): item=0 name="test/" inode=401409 ... nametype=PARENT type=PATH msg=audit(1416955786.566:89): item=1 name="test/567" inode=393804 ... nametype=NORMAL This issue was brought up by a number of people, but special credit should go to hujianyang@huawei.com for reporting the problem along with an explanation of the problem and a patch.

2014-12-22crypto: af_alg - fix backlog handlingRabin Vincent
If a request is backlogged, it's complete() handler will get called twice: once with -EINPROGRESS, and once with the final error code. af_alg's complete handler, unlike other users, does not handle the -EINPROGRESS but instead always completes the completion that recvmsg() is waiting on. This can lead to a return to user space while the request is still pending in the driver. If userspace closes the sockets before the requests are handled by the driver, this will lead to use-after-frees (and potential crashes) in the kernel due to the tfm having been freed. The crashes can be easily reproduced (for example) by reducing the max queue length in cryptod.c and running the following (from http://www.chronox.de/libkcapi.html) on AES-NI capable hardware: $ while true; do kcapi -x 1 -e -c '__ecb-aes-aesni' \ -k 00000000000000000000000000000000 \ -p 00000000000000000000000000000000 >/dev/null & done Cc: stable@vger.kernel.org Signed-off-by: Rabin Vincent <rabin.vincent@axis.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

Unfortunately in the same time the commit 4904a82a9399 (arm: mvebu: move Armada 370/XP pinctrl node definition armada-370-xp.dtsi) was merged and it introduced again the hog pins muxing.

2014-12-19audit: use supplied gfp_mask from audit_buffer in kauditd_send_multicast_skbRichard Guy Briggs
Eric Paris explains: Since kauditd_send_multicast_skb() gets called in audit_log_end(), which can come from any context (aka even a sleeping context) GFP_KERNEL can't be used. Since the audit_buffer knows what context it should use, pass that down and use that.

2014-12-19audit: don't attempt to lookup PIDs when changing PID filtering audit rulesPaul Moore
Commit f1dc4867 ("audit: anchor all pid references in the initial pid namespace") introduced a find_vpid() call when adding/removing audit rules with PID/PPID filters; unfortunately this is problematic as find_vpid() only works if there is a task with the associated PID alive on the system. The following commands demonstrate a simple reproducer. # auditctl -D # auditctl -l # autrace /bin/true # auditctl -l This patch resolves the problem by simply using the PID provided by the user without any additional validation, e.g. no calls to check to see if the task/PID exists.
