commit bed3d9c0 upstream. commit 7a532fe7 ath9k_hw: fix interpretation of the rx KeyMiss flag This commit used the rx key miss indication to detect packets that were passed from the hardware without being decrypted, however it seems that this bit is not only undefined in the static WEP case, but also for dynamically allocated WEP keys. This caused a regression when using WEP-LEAP. This patch fixes the regression by keeping track of which key indexes refer to CCMP keys and only using the key miss indication for those. Reported-by:

commit f03ba7e9 upstream. After association, STA will go through eapol handshake with WPS enabled AP. It's observed that WPS handshake fails with some 11n AP. The reason for the failure is that the eapol packet is sent via 11n frame aggregation. The eapol packet should be sent directly without 11n aggregation. This patch fixes the problem by adding WPS session control while dequeuing Tx packets for transmission. Signed-off-by:

commit 92583924 upstream. Currently we check the sequence number of last packet received against start_win. If a sequence hole is detected, start_win is updated to next sequence number. Since the rx sequence number is initialized to 0, a corner case exists when BA setup happens immediately after association. As 0 is a valid sequence number, start_win gets increased to 1 incorrectly. This causes the first packet with sequence number 0 being dropped. Initialize rx sequence number as 0xffff and skip adjusting start_win if the sequence number remains 0xffff. The sequence number will be updated once the first packet is received. Signed-off-by:

commit 32587371 upstream. Fix a regression introduced by 7eaceacc ("block: remove per-queue plugging"). In that patch, Jens removed the whole mm_unplug_device() function, which used to be the trigger to make umem start to work. We need to implement unplugging to make umem start to work, or I/O will never be triggered. Signed-off-by:

commit 047fe360 upstream. Dave Jones reported a kernel BUG at mm/slub.c:3474! triggered by splice_shrink_spd() called from vmsplice_to_pipe() commit 35f3d14d (pipe: add support for shrinking and growing pipes) added capability to adjust pipe->buffers. Problem is some paths don't hold pipe mutex and assume pipe->buffers doesn't change for their duration. Fix this by adding nr_pages_max field in struct splice_pipe_desc, and use it in place of pipe->buffers where appropriate. splice_shrink_spd() loses its struct pipe_inode_info argument. Reported-by:

commit 5870adc6 upstream. bug introduced with 59b699cd If the source or destination mac address of an ethernet packet could not be found in the translation table the packet was dropped if AP isolation was turned on. This behavior would make it impossible to send broadcast packets over the mesh as the broadcast address will never enter the translation table. Signed-off-by:

commit 5f160126 upstream. The acpi_pad driver can get stuck in destroy_power_saving_task() waiting for kthread_stop() to stop a power_saving thread. The problem is that the isolated_cpus_lock mutex is owned when destroy_power_saving_task() calls kthread_stop(), which waits for a power_saving thread to end, and the power_saving thread tries to acquire the isolated_cpus_lock when it calls round_robin_cpu(). This patch fixes the issue by making round_robin_cpu() use its own mutex. https://bugzilla.kernel.org/show_bug.cgi?id=42981Signed-off-by:

commit 85f2f834 upstream. The freescale arm i.MX series platform can support this driver, and usually the arm cpu works in the little endian mode by default, while device tree entry value is stored in big endian format, we should use be32_to_cpup() to handle them, after modification, it can work well both on the le cpu and be cpu.

commit eb3979f6 upstream. Distribution kernel maintainers routinely backport fixes for users that were deemed important but not "something critical" as defined by the rules. To users of these kernels they are very serious and failing to fix them reduces the value of -stable. The problem is that the patches fixing these issues are often subtle and prone to regressions in other ways and need greater care and attention. To combat this, these "serious" backports should have a higher barrier to entry. This patch relaxes the rules to allow a distribution maintainer to merge to -stable a backported patch or small series that fixes a "serious" user-visible performance issue. They should include additional information on the user-visible bug affected and a link to the bugzilla entry if available. The same rules about the patch being already in mainline still apply.

commit 4ad33411 upstream. It makes sense to label "Digital Thermal Sensor" as "DTS", but unfortunately the string "dts" was already used for "Debug Store", and /proc/cpuinfo is a user space ABI. Therefore, rename this to "dtherm".

commit 58bf8062 upstream. After banging my head against this for the past few months, I still don't see how this could possible race under the premise that once an irq bit is masked in PM_IMR and reset in PM_IIR it won't show up again until we unmask it in PM_IMR. Still, we have reports of this being seen in the wild. Now Bspec has this little bit of lovely language in the PMIIR register: Public SNB Docs, Vol3Part2, 2.5.14 "PMIIR": "For each bit, the IIR can store a second pending interrupt if two or more of the same interrupt conditions occur before the first condition is cleared. Upon clearing the interrupt, the IIR bit will momentarily go low, then return high to indicate there is another interrupt pending." Now if we presume that PMIMR only prevent new interrupts from being queued, we could easily end up masking an interrupt and clearing it, but the 2nd pending interrupt setting the bit in PMIIR right away again. Which leads, the next time the irq handler runs, to hitting the WARN. Also, no bad side effects of this have ever been reported. And we've tracked down our issues with the gpu turbo getting stuck to bogus interrupt generation limits in th RPLIMIT register. So let's just rip out this WARN as bogus and call it a day. The only shallow thing here is that this 2-deep irq queue in the hw makes you wonder how racy the windows irq handler is ... Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=42907Acked-by:

commit e734568b upstream. The OProfile perf backend uses a static array to keep track of the perf events on the system. When compiling with CONFIG_CPUMASK_OFFSTACK=y && SMP, nr_cpumask_bits is not a compile-time constant and the build will fail with: oprofile_perf.c:28: error: variably modified 'perf_events' at file scope This patch uses NR_CPUs instead of nr_cpumask_bits for the array initialisation. If this causes space problems in the future, we can always move to dynamic allocation for the events array. Cc: Matt Fleming <matt@console-pimps.org> Reported-by:

commit f18e3c6b upstream. "ath9k: Fix softlockup in AR9485" with commit id 64bc1239 fixed the reported issue, yet its better to avoid the possible infinite loop in ar9003_get_pll_sqsum_dvc by having a timeout as suggested by ath9k maintainers. http://www.spinics.net/lists/linux-wireless/msg92126.html. Based on my testing PLL's locking measurement is done in ~200us (2 iterations).

commit 2c995ff8 upstream. skb_linearize(skb) possibly rearranges the skb internal data and then changes the skb->data pointer value. For this reason any other pointer in the code that was assigned skb->data before invoking skb_linearise(skb) must be re-assigned. In the current tt_query message handling code this is not done and therefore, in case of skb linearization, the pointer used to handle the packet header ends up in pointing to free'd memory.

commit fe20b39e upstream. reg_timeout_work() calls restore_regulatory_settings() which takes cfg80211_mutex. reg_set_request_processed() already holds cfg80211_mutex before calling cancel_delayed_work_sync(reg_timeout), so it might deadlock. Call the async cancel_delayed_work instead, in order to avoid the potential deadlock.

commit 2031b4c2 upstream. this patch is dependent on the patch "cfg80211: fix interface combinations" In ath9k currently we have ADHOC interface as a single incompatible interface. when drv_add_interface is called during resume we got to consider number of vifs already present in addition to checking the drivers 'opmode' information about ADHOC. we incorrectly assume an ADHOC interface is already present. Then we may miss some driver specific data for the ADHOC interface after resume. The above mentioned checks can be removed from the driver, as the patch 'cfg80211: fix interface combinations' ensures that if an interface type is not advertised by the driver in any of the interface combinations(via ieee80211_iface_combination) then it shall be treated as a single incompatible interface. Fixes the following warning on suspend/resume with ibss interface. ath: phy0: Cannot create ADHOC interface when other interfaces already exist.

commit 03aaae7c upstream. Fix a significant memory leak inadvertently introduced during simplification of cell_release_singleton() in commit 6f94a4c4 ("dm thin: fix stacked bi_next usage"). A cell's hlist_del() must be accompanied by a mempool_free(). Use __cell_release() to do this, like before. Signed-off-by:

commit 9bd0c15f upstream. nv_two_heads() was never meant to be used outside of pre-nv50 code. The code checks for >= NV_10 for 2 CRTCs, then downgrades a few specific chipsets to 1 CRTC based on (pci_device & 0x0ff0). The breakage example seen is on GTX 560Ti, with a pciid of 0x1200, which gets detected as an NV20 (0x020x) with 1 CRTC by nv_two_heads(), causing memory corruption because there's actually 2 CRTCs.. This switches fbcon to use the CRTC count directly from the mode_config structure, which will also fix the same issue on Kepler boards which have 4 CRTCs. Signed-off-by:

commit 0d05568a upstream. rtsx_transport.c (rtsx_transfer_sglist_adma_partial): pointer struct scatterlist *sg, which is mapped in dma_map_sg, is used as an iterator in later transfer operation. It is corrupted and passed to dma_unmap_sg, thus causing fatal unmap of some erroneous address. Fix it by duplicating *sg_ptr for iterating. Signed-off-by:
