[ Upstream commit bb53f4d4 ] The 8000 series adapters uses catch-all filters for encapsulated traffic to support filtering VXLAN, NVGRE and GENEVE traffic. This new filter functionality requires a longer MCDI command. This patch increases the size of buffers on stack that were missed, which fixes a kernel panic from the stack protector.

[ Upstream commit 60abc0be ] The per netns loopback_dev->ip6_ptr is unregistered and set to NULL when its mtu is set to smaller than IPV6_MIN_MTU, this leads to that we could set rt->rt6i_idev NULL after a rt6_uncached_list_flush_dev() and then crash after another call. In this case we should just bring its inet6_dev down, rather than unregistering it, at least prior to commit 176c39af ("netns: fix addrconf_ifdown kernel panic") we always override the case for loopback. Thanks a lot to Andrey for finding a reliable reproducer. Fixes: 176c39af ("netns: fix addrconf_ifdown kernel panic") Reported-by:

[ Upstream commit b866203d ] The commit ("net/phy: micrel: Add workaround for bad autoneg") fixes an autoneg failure case by resetting the hardware. This turns off intterupts. Things will work themselves out if the phy polls, as it will figure out it's state during a poll. However if the phy uses only intterupts, the phy will stall, since interrupts are off. This patch fixes the issue by calling config_intr after resetting the phy. Fixes: d2fd719b ("net/phy: micrel: Add workaround for bad autoneg ") Signed-off-by:

commit 99c13b8c upstream. The pat_enabled() logic is broken on CPUs which do not support PAT and where the initialization code fails to call pat_init(). Due to that the enabled flag stays true and pat_enabled() returns true wrongfully. As a consequence the mappings, e.g. for Xorg, are set up with the wrong caching mode and the required MTRR setups are omitted. To cure this the following changes are required: 1) Make pat_enabled() return true only if PAT initialization was invoked and successful. 2) Invoke init_cache_modes() unconditionally in setup_arch() and remove the extra callsites in pat_disable() and the pat disabled code path in pat_init(). Also rename __pat_enabled to pat_disabled to reflect the real purpose of this variable. Fixes: 9cd25aac ("x86/mm/pat: Emulate PAT when it is disabled") Signed-off-by:

commit 42cfcafb upstream. Changes in the SW cts (ciphertext stealing) code in commit 0605c41c ("crypto: cts - Convert to skcipher") revealed a problem in the CAAM driver: when cts(cbc(aes)) is executed and cts runs in SW, cbc(aes) is offloaded in CAAM; cts encrypts the last block in atomic context and CAAM incorrectly decides to use GFP_KERNEL for memory allocation. Fix this by allowing GFP_KERNEL (sleeping) only when MAY_SLEEP flag is set, i.e. remove MAY_BACKLOG flag. We split the fix in two parts - first is sent to -stable, while the second is not (since there is no known failure case).

commit a9332e9a upstream. There is a clean-up bug in the core comedi module initialization functions, `comedi_init()`. If the `comedi_num_legacy_minors` module parameter is non-zero (and valid), it creates that many "legacy" devices and registers them in SysFS. A failure causes the function to clean up and return an error. Unfortunately, it fails to destroy the "comedi" class that was created earlier. Fix it by adding a call to `class_destroy(comedi_class)` at the appropriate place in the clean-up sequence. Signed-off-by:

commit a0c4acd2 upstream. If a writer could been woken up, the above branch if (sem->count == 0) break; would have moved us to taking the sem. So, it's not the time to wake a writer now, and only readers are allowed now. Thus, 0 must be passed to __rwsem_do_wake(). Next, __rwsem_do_wake() wakes readers unconditionally. But we mustn't do that if the sem is owned by writer in the moment. Otherwise, writer and reader own the sem the same time, which leads to memory corruption in callers. rwsem-xadd.c does not need that, as: 1) the similar check is made lockless there, 2) in __rwsem_mark_wake::try_reader_grant we test, that sem is not owned by writer.

Self-destruct in 5 seconds. Have a nice day... > BUG: unable to handle kernel NULL pointer dereference at (null) > IP: _raw_spin_lock+0xc/0x30 > PGD 0 Fix this by taking a reference to the super block in proc_sys_prune_dcache. The superblock reference is the core of the fix however the sysctl_inodes list is converted to a hlist so that hlist_del_init_rcu may be used. This allows proc_sys_prune_dache to remove inodes the sysctl_inodes list, while not causing problems for proc_sys_evict_inode when if it later choses to remove the inode from the sysctl_inodes list. Removing inodes from the sysctl_inodes list allows proc_sys_prune_dcache to have a progress guarantee, while still being able to drop all locks. The fact that head->unregistering is set in start_unregistering ensures that no more inodes will be added to the the sysctl_inodes list. Previously the code did a dance where it delayed calling iput until the next entry in the list was being considered to ensure the inode remained on the sysctl_inodes list until the next entry was walked to. The structure of the loop in this patch does not need that so is much easier to understand and maintain. Reported-by:

commit f991af3d upstream. The retry logic for netlink_attachskb() inside sys_mq_notify() is nasty and vulnerable: 1) The sock refcnt is already released when retry is needed 2) The fd is controllable by user-space because we already release the file refcnt so we when retry but the fd has been just closed by user-space during this small window, we end up calling netlink_detachskb() on the error path which releases the sock again, later when the user-space closes this socket a use-after-free could be triggered. Setting 'sock' to NULL here should be sufficient to fix it. Reported-by:

commit fe0dfd63 upstream. Thinkpad Helix 2 is a tablet PC, the audio is powered by Core M broadwell-audio and rt286 codec. For all versions of Linux kernel, the stereo output doesn't work properly when earphones are plugged in, the sound was coming out from both channels even if the audio contains only the left or right channel. Furthermore, if a music recorded in stereo is played, the two channels cancle out each other out, as a result, no voice but only distorted background music can be heard, like a sound card with builtin a Karaoke sount effect. Apparently this tablet uses a combo jack with polarity incorrectly set by rt286 driver. This patch adds DMI information of Thinkpad Helix 2 to force_combo_jack_table[] and the issue is resolved. The microphone input doesn't work regardless to the presence of this patch and still needs help from other developers to investigate. This is my first patch to LKML directly, sorry for CC-ing too many people here. Link: https://bugzilla.kernel.org/show_bug.cgi?id=93841Signed-off-by:

commit 236222d3 upstream. According to the Intel datasheet, the REP MOVSB instruction exposes a pretty heavy setup cost (50 ticks), which hurts short string copy operations. This change tries to avoid this cost by calling the explicit loop available in the unrolled code for strings shorter than 64 bytes. The 64 bytes cutoff value is arbitrary from the code logic point of view - it has been selected based on measurements, as the largest value that still ensures a measurable gain. Micro benchmarks of the __copy_from_user() function with lengths in the [0-63] range show this performance gain (shorter the string, larger the gain): - in the [55%-4%] range on Intel Xeon(R) CPU E5-2690 v4 - in the [72%-9%] range on Intel Core i7-4810MQ Other tested CPUs - namely Intel Atom S1260 and AMD Opteron 8216 - show no difference, because they do not expose the ERMS feature bit.

commit d1bd4a79 upstream. If a TPM2 loses power without a TPM2_Shutdown command being issued (a "disorderly reboot"), it may lose some state that has yet to be persisted to NVRam, and will increment the DA counter. After the DA counter gets sufficiently large, the TPM will lock the user out. NOTE: This only changes behavior on TPM2 devices. Since TPM1 uses sysfs, and sysfs relies on implicit locking on chip->ops, it is not safe to allow this code to run in TPM1, or to add sysfs support to TPM2, until that locking is made explicit.

commit da6c2add upstream. To set the mux mode of a pin two bits must be set. Up to now this is implemented using the following idiom: writel(mask, reg + CLR); writel(value, reg + SET); . This however results in the mux mode being 0 between the two writes. On my machine there is an IC's reset pin connected to LCD_D20. The bootloader configures this pin as GPIO output-high (i.e. not holding the IC in reset). When Linux reconfigures the pin to GPIO the short time LCD_D20 is muxed as LCD_D20 instead of GPIO_1_20 is enough to confuse the connected IC. The same problem is present for the pin's drive strength setting which is reset to low drive strength before using the right value. So instead of relying on the hardware to modify the register setting using two writes implement the bit toggling using read-modify-write.

commit b7c747d4 upstream. In stm32_pconf_parse_conf function, stm32_pmx_gpio_set_direction is called with wrong parameter value. Indeed, using NULL value for range will raise an oops. Fixes: aceb16dc ("pinctrl: Add STM32 MCUs support") Reported-by:

commit 97ba26b8 upstream. The nand_groups table uses different names for the NAND DQS pins than the GROUP() definition in meson8b_cbus_groups (nand_dqs_0 vs nand_dqs0). This prevents using the NAND DQS pins in the devicetree. Fix this by ensuring that the GROUP() definition and the meson8b_cbus_groups use the same name for these pins.

commit 3908632f upstream. The R8A7791 PFC driver was apparently based on the preliminary revisions of the user's manual, which omitted the DVC_MUTE signal altogether in the PFC section. The modern manual has the signal described, so just add the necassary data to the driver... Fixes: 50884519 ("pinctrl: sh-pfc: r8a7791 PFC support") Signed-off-by:

commit 58439280 upstream. PINMUX_IPSR_MSEL() macro invocation for the TX2 signal has apparently wrong 1st argument -- most probably a result of cut&paste programming... Fixes: 50884519 ("pinctrl: sh-pfc: r8a7791 PFC support") Signed-off-by:

commit 5f4c8caf upstream. All R8A7794 manuals I have here (0.50 and 1.10) agree that the PFC driver has ATAG0# and ATAWR0# signals in IPSR12 swapped -- fix this. Fixes: 43c4436e ("pinctrl: sh-pfc: add R8A7794 PFC support") Signed-off-by:

commit f70b281b upstream. The sysfs cpu_capacity entry for each CPU has nothing to do with PROC_FS, nor it's in /proc/sys path. Remove such ifdef. Cc: Russell King <linux@arm.linux.org.uk> Reported-and-suggested-by:
