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 5ecce4c9 upstream. The ib_uverbs_create_ah() ind ib_uverbs_modify_qp() calls receive the port number from user input as part of its attributes and assumes it is valid. Down on the stack, that parameter is used to access kernel data structures. If the value is invalid, the kernel accesses memory it should not. To prevent this, verify the port number before using it.

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 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 70365027 upstream. After commit 47c950d1 ("pinctrl: cherryview: Do not add all southwest and north GPIOs to IRQ domain") the driver does not add all GPIOs to the irqdomain. The reason for that is that those GPIOs cannot generate IRQs at all, only GPEs (General Purpose Events). This causes Linux virtual IRQ numbering to change. However, it seems some CYAN Chromebooks, including Acer Chromebook hardcodes these Linux IRQ numbers in the ACPI tables of the machine. Since the numbering is different now, the IRQ meant for keyboard does not match the Linux virtual IRQ number anymore making the keyboard non-functional. Work this around by adding special quirk just for these machines where we add back all GPIOs to the irqdomain. Rest of the Cherryview/Braswell based machines will not be affected by the change.

commit 6836796d upstream.

Avoid making these calls. This problem manifested as intermittent cases where the au8522 would be reset on analog video startup, in particular when starting up ALSA audio streaming in parallel - the sysfs entries created by snd-usb-audio on streaming startup would result in unsupported control messages being sent during tuning which would put the chip into an unknown state.
