Public bug reported:
SRU Justification
Impact:
The upstream process for stable tree updates is quite similar
in scope to the Ubuntu SRU process, e.g., each patch has to
demonstrably fix a bug, and each patch is vetted by upstream
by originating either directly from a mainline/stable Linux tree or
a minimally backported form of that patch. The v4.4.21 upstream stable
patch set is now available. It should be included in the Ubuntu
kernel as well.
git://git.kernel.org/
TEST CASE: TBD
The following patches from the v4.4.21 stable release shall be
applied:
Revert "i40e: fix: do not sleep in netdev_ops"
fs: Check for invalid i_uid in may_follow_link()
netfilter: x_tables: check for size overflow
ext4: validate that metadata blocks do not overlap superblock
ext4: fix xattr shifting when expanding inodes
ext4: fix xattr shifting when expanding inodes part 2
ext4: properly align shifted xattrs when expanding inodes
ext4: avoid deadlock when expanding inode size
ext4: avoid modifying checksum fields directly during checksum verification
block: Fix race triggered by blk_set_queue_dying()
block: make sure a big bio is split into at most 256 bvecs
cgroup: reduce read locked section of cgroup_threadgroup_rwsem during fork
s390/sclp_ctl: fix potential information leak with /dev/sclp
drm/radeon: fix radeon_move_blit on 32bit systems
drm: Reject page_flip for !DRIVER_MODESET
drm/msm: fix use of copy_from_user() while holding spinlock
ASoC: atmel_ssc_dai: Don't unconditionally reset SSC on stream startup
xfs: fix superblock inprogress check
timekeeping: Cap array access in timekeeping_debug
timekeeping: Avoid taking lock in NMI path with CONFIG_DEBUG_TIMEKEEPING
lustre: remove unused declaration
wrappers for ->i_mutex access
ovl: don't copy up opaqueness
ovl: remove posix_acl_default from workdir
ovl: listxattr: use strnlen()
ovl: fix workdir creation
ubifs: Fix assertion in layout_in_gaps()
bcache: RESERVE_PRIO is too small by one when prio_buckets() is a power of two.
vhost/scsi: fix reuse of &vq->iov[out] in response
x86/apic: Do not init irq remapping if ioapic is disabled
uprobes: Fix the memcg accounting
crypto: caam - fix IV loading for authenc (giv)decryption
ALSA: usb-audio: Add sample rate inquiry quirk for B850V3 CP2114
ALSA: firewire-tascam: accessing to user space outside spinlock
ALSA: fireworks: accessing to user space outside spinlock
ALSA: rawmidi: Fix possible deadlock with virmidi registration
ALSA: hda - Add headset mic quirk for Dell Inspiron 5468
ALSA: hda - Enable subwoofer on Dell Inspiron 7559
ALSA: timer: fix NULL pointer dereference in read()/ioctl() race
ALSA: timer: fix division by zero after SNDRV_TIMER_IOCTL_CONTINUE
ALSA: timer: fix NULL pointer dereference on memory allocation failure
scsi: fix upper bounds check of sense key in scsi_sense_key_string()
metag: Fix atomic_*_return inline asm constraints
cpufreq: Fix GOV_LIMITS handling for the userspace governor
hwrng: exynos - Disable runtime PM on probe failure
