The user timer tu->qused counter may go to a negative value when multiple concurrent reads are performed since both the check and the decrement of tu->qused are done in two individual locked contexts. This results in bogus read outs, and the endless loop in the user-space side. The fix is to move the decrement of the tu->qused counter into the same spinlock context as the zero-check of the counter. Cc: <stable@vger.kernel.org> Signed-off-by: NTakashi Iwai <tiwai@suse.de>

The i.MX51 datasheet says: Chapter 56.1.2.4 I2S Mode ... When I2S modes are entered (I2S master (01) or I2S slave (10)), the following settings are recommended: ... - TX Frame Rate should be 2 i.e. (STCCR[12:8] = 1) - RX Frame Rate should be 2 i.e. (SRCCR[12:8] = 1) Chapter 56.3.3.12 SSI Transmit and Receive Clock Control Registers (STCCR & SRCCR) ... Bits 12-8 DC4-DC0 Frame Rate Divider Control. These bits are used to control the divide ratio for the programmable frame rate dividers. The divide ratio works on the word clock. In Normal mode, this ratio determines the word transfer rate. In Network mode, this ratio sets the number of words per frame. The divide ratio ranges from 1 to 32 in Normal mode and from 2 to 32 in Network mode. In Normal mode, a divide ratio of 1 (DC=00000) provides continuous periodic data word transfer. A bit-length frame sync must be used in this case. Function fsl_ssi_hw_params() setup Normal mode for MONO output, so with DC=0, SSI enters to continuous periodic data word transfer. To fix this, setup DC for any I2S mode. Patch has tested on custom board based on Digi CCMX-51 module (i.MX51).

Commit fe742fd4 ("Revert "btrfs: switch to ->iterate_shared()"") backed out the conversion to ->iterate_shared() for Btrfs because the delayed inode handling in btrfs_real_readdir() is racy. However, we can still do readdir in parallel if there are no delayed nodes. This is a temporary fix which upgrades the shared inode lock to an exclusive lock only when we have delayed items until we come up with a more complete solution. While we're here, rename the btrfs_{get,put}_delayed_items functions to make it very clear that they're just for readdir. Tested with xfstests and by doing a parallel kernel build: while make tinyconfig && make -j4 && git clean dqfx; do : done along with a bunch of parallel finds in another shell: while true; do for ((i=0; i<4; i++)); do find . >/dev/null & done wait done Signed-off-by: NOmar Sandoval <osandov@fb.com> Signed-off-by: NDavid Sterba <dsterba@suse.com> Signed-off-by: NChris Mason <clm@fb.com>

The value `bytes' comes from the filesystem which is about to be mounted. We cannot trust that the value is always in the range we expect it to be. Check its value before using it to calculate the length for the crc32_le call. It value must be larger (or equal) sumoff + 4. This fixes a kernel bug when accidentially mounting an image file which had the nilfs2 magic value 0x3434 at the right offset 0x406 by chance. The bytes 0x01 0x00 were stored at 0x408 and were interpreted as a s_bytes value of 1. This caused an underflow when substracting sumoff + 4 (20) in the call to crc32_le.

Tetsuo has reported the following potential oom_killer_disable vs. oom_reaper race: (1) freeze_processes() starts freezing user space threads. (2) Somebody (maybe a kenrel thread) calls out_of_memory(). (3) The OOM killer calls mark_oom_victim() on a user space thread P1 which is already in __refrigerator(). (4) oom_killer_disable() sets oom_killer_disabled = true. (5) P1 leaves __refrigerator() and enters do_exit(). (6) The OOM reaper calls exit_oom_victim(P1) before P1 can call exit_oom_victim(P1). (7) oom_killer_disable() returns while P1 not yet finished (8) P1 perform IO/interfere with the freezer. This situation is unfortunate. We cannot move oom_killer_disable after all the freezable kernel threads are frozen because the oom victim might depend on some of those kthreads to make a forward progress to exit so we could deadlock. It is also far from trivial to teach the oom_reaper to not call exit_oom_victim() because then we would lose a guarantee of the OOM killer and oom_killer_disable forward progress because exit_mm->mmput might block and never call exit_oom_victim. It seems the easiest way forward is to workaround this race by calling try_to_freeze_tasks again after oom_killer_disable. This will make sure that all the tasks are frozen or it bails out.
