git://anongit.freedesktop.org/drm-intel into drm-fixes Yeah a pull for one patch is a bit overkill but I started to assemble the various patches for 3.20 in a branch for atomic props/ioctl and didn't realize that this bugfix here at the beginnning of the branch should be in 3.19 (because msm is using the helpers arleady). So if you'd merge we'd have it twice or or I need to shuffle branches again.

2014-12-22caif: Fix napi poll list corruptionHerbert Xu
The commit d75b1ade567ffab085e8adbbdacf0092d10cd09c (net: less interrupt masking in NAPI) breaks caif. 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 caif 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 caif.

While the Mentor/Alcatel PE-MCXMAC IP core is also used in other designs (Freescale Gianfar/UCC, QLogic NetXen, Solarflare, Agere ET-1310, Netlogic XLR/XLS), none of these use this driver as it heavily depends on the s6000 DMA engine.

2014-12-22tg3: tg3_disable_ints using uninitialized mailbox value to disable interruptsPrashant Sreedharan
During driver load in tg3_init_one, if the driver detects DMA activity before intializing the chip tg3_halt is called. As part of tg3_halt interrupts are disabled using routine tg3_disable_ints. This routine was using mailbox value which was not initialized (default value is 0). As a result driver was writing 0x00000001 to pci config space register 0, which is the vendor id / device id. This driver bug was exposed because of the commit a7877b17a667 (PCI: Check only the Vendor ID to identify Configuration Request Retry). Also this issue is only seen in older generation chipsets like 5722 because config space write to offset 0 from driver is possible. The newer generation chips ignore writes to offset 0. Also without commit a7877b17a667, for these older chips when a GRC reset is issued the Bootcode would reprogram the vendor id/device id, which is the reason this bug was masked earlier. Fixed by initializing the interrupt mailbox registers before calling tg3_halt. Please queue for -stable.

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.

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>

2014-12-21udf: Check component length before reading itJan Kara
Check that length specified in a component of a symlink fits in the input buffer we are reading. Also properly ignore component length for component types that do not use it. Otherwise we read memory after end of buffer for corrupted udf image. Reported-by: Carl Henrik Lunde <chlunde@ping.uio.no> CC: stable@vger.kernel.org Signed-off-by: Jan Kara <jack@suse.cz>

2014-12-21thermal: cpu_cooling: document node in struct cpufreq_cooling_deviceJavi Merino
The node field of struct cpufreq_cooling_device was reintroduced in 2dcd851fe4b4 (thermal: cpu_cooling: Update always cpufreq policy with thermal constraints) but without the documentation that it once had. Add it back so that all the fields of struct cpufreq_cooling_device are documented.
