commit a5e8e825 upstream. The readdir() function is thread safe as long as just one thread uses a DIR, which is the case in 'perf script', so, 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 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 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.

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.

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:

commit 6836796d upstream. The USB core and sysfs will attempt to enumerate certain parameters which are unsupported by the au0828 - causing inconsistent behavior and sometimes causing the chip to reset. 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.

commit 04fb365c upstream. %p will leak kernel pointers, so let's not expose the information on dmesg and instead use %pK. %pK will only show the actual addresses if explicitly enabled under /proc/sys/kernel/kptr_restrict. Acked-by:

commit 9e52b325 upstream. Always try to parse an address, since kstrtoul() will safely fail when given a symbol as input. If that fails (which will be the case for a symbol), try to parse a symbol instead. This allows creating a probe such as: p:probe/vlan_gro_receive 8021q:vlan_gro_receive+0 Which is necessary for this command to work: perf probe -m 8021q -a vlan_gro_receive Link: http://lkml.kernel.org/r/fd72d666f45b114e2c5b9cf7e27b91de1ec966f1.1498122881.git.sd@queasysnail.net Fixes: 413d37d1 ("tracing: Add kprobe-based event tracer") Acked-by:

Added debugging output reveals that we enter the function with sc->gfp_mask == GFP_NOFS|__GFP_NOFAIL|__GFP_HARDWALL|__GFP_MOVABLE requested_highidx = gfp_zone(sc->gfp_mask) == 2 (ZONE_NORMAL) Inside the for loop, however: gfp_zone(sc->gfp_mask) == 3 (ZONE_MOVABLE) This means we have gone through this branch: if (buffer_heads_over_limit) sc->gfp_mask |= __GFP_HIGHMEM; This changes the gfp_zone() result, but requested_highidx remains unchanged. On nodes where the only populated zone is movable, the inner while loop will check only lower zones, which are not populated, and underflow classzone_idx. To sum up, the bug occurs in configurations with ZONE_MOVABLE (such as when booted with the movable_node parameter) and only in situations when buffer_heads_over_limit is true, and there's an allocation with __GFP_MOVABLE and without __GFP_HIGHMEM performing direct reclaim. This patch makes sure that classzone_idx starts with the correct zone. Mainline has been affected in versions 4.6 and 4.7, but the culprit commit has been also included in stable trees. In mainline, this has been fixed accidentally as part of 34-patch series (plus follow-up fixes) "Move LRU page reclaim from zones to nodes", which makes the mainline commit unsuitable for stable backport, unfortunately.
