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 following upstream
stable patches should be included in the Ubuntu kernel:
v5.4.218 upstream stable release
from git://git.kernel.org/
mm: pagewalk: Fix race between unmap and page walker
perf tools: Fixup get_current_dir_name() compilation
firmware: arm_scmi: Add SCMI PM driver remove routine
dmaengine: xilinx_dma: cleanup for fetching xlnx,num-fstores property
dmaengine: xilinx_dma: Report error in case of dma_set_mask_and_coherent API
failure
ARM: dts: fix Moxa SDIO 'compatible', remove 'sdhci' misnomer
scsi: qedf: Fix a UAF bug in __qedf_probe()
net/ieee802154: fix uninit value bug in dgram_sendmsg
um: Cleanup syscall_handler_t cast in syscalls_32.h
um: Cleanup compiler warning in arch/x86/um/tls_32.c
arch: um: Mark the stack non-executable to fix a binutils warning
usb: mon: make mmapped memory read only
USB: serial: ftdi_sio: fix 300 bps rate for SIO
mmc: core: Replace with already defined values for readability
mmc: core: Terminate infinite loop in SD-UHS voltage switch
rpmsg: qcom: glink: replace strncpy() with strscpy_pad()
nilfs2: fix NULL pointer dereference at nilfs_bmap_lookup_at_level()
nilfs2: fix leak of nilfs_root in case of writer thread creation failure
nilfs2: replace WARN_ONs by nilfs_error for checkpoint acquisition failure
ceph: don't truncate file in atomic_open
random: clamp credited irq bits to maximum mixed
ALSA: hda: Fix position reporting on Poulsbo
efi: Correct Macmini DMI match in uefi cert quirk
USB: serial: qcserial: add new usb-id for Dell branded EM7455
random: restore O_NONBLOCK support
random: avoid reading two cache lines on irq randomness
random: use expired timer rather than wq for mixing fast pool
Input: xpad - add supported devices as contributed on github
Input: xpad - fix wireless 360 controller breaking after suspend
Linux 5.4.218
