commit 22a9f41b upstream. The readdir() function is thread safe as long as just one thread uses a DIR, which is the case when parsing tracepoint event definitions, to avoid breaking the build with glibc-2.23.90 (upcoming 2.24), use it instead of readdir_r(). See: http://man7.org/linux/man-pages/man3/readdir.3.html "However, in modern implementations (including the glibc implementation), concurrent calls to readdir() that specify different directory streams are thread-safe. In cases where multiple threads must read from the same directory stream, using readdir() with external synchronization is still preferable to the use of the deprecated readdir_r(3) function."

commit 3ed5ca2e upstream. We catch this record to provide a visual indication that events are getting lost, then call the default method to allow extra logging shared with the other tools to take place. This extra logging was done twice because we were continuing to the "default" clause where machine__process_event() will end up calling machine__process_lost_event() again, fix it.

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 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 7903d4f5 upstream. We use well known standard names for functions that have name, such as I2C, SPI, SPDIF, etc.. Fix the function name of SPDIF, which was named OWA (One Wire Audio) based on Allwinner datasheets. Fixes: 4730f33f ("pinctrl: sunxi: add allwinner A83T PIO controller support") Signed-off-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 425fffd8 upstream. Currently, inputting the following command will succeed but actually the value will be truncated: # echo 0x12ffffffff > /proc/sys/net/ipv4/tcp_notsent_lowat This is not friendly to the user, so instead, we should report error when the value is larger than UINT_MAX.

commit 5380e564 upstream. I saw some very confusing sysctl output on my system: # cat /proc/sys/net/core/xfrm_aevent_rseqth -2 # cat /proc/sys/net/core/xfrm_aevent_etime -10 # cat /proc/sys/net/ipv4/tcp_notsent_lowat -4294967295 Because we forget to set the *negp flag in proc_douintvec, so it will become a garbage value. Since the value related to proc_douintvec is always an unsigned integer, so we can set *negp to false explictily to fix this issue.

commit b3b51417 upstream. The usbip stack dynamically allocates the transfer_buffer and setup_packet of each urb that got generated by the tcp to usb stub code. As these pointers are always used only once we will set them to NULL after use. This is done likewise to the free_urb code in vudc_dev.c. This patch fixes double kfree situations where the usbip remote side added the URB_FREE_BUFFER. Signed-off-by:
