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:
v5.18.1 upstream stable release
from git://git.kernel.org/
lockdown: also lock down previous kgdb use
HID: amd_sfh: Add support for sensor discovery
random: fix sysctl documentation nits
init: call time_init() before rand_initialize()
ia64: define get_cycles macro for arch-override
s390: define get_cycles macro for arch-override
parisc: define get_cycles macro for arch-override
alpha: define get_cycles macro for arch-override
powerpc: define get_cycles macro for arch-override
timekeeping: Add raw clock fallback for random_get_entropy()
m68k: use fallback for random_get_entropy() instead of zero
riscv: use fallback for random_get_entropy() instead of zero
mips: use fallback for random_get_entropy() instead of just c0 random
arm: use fallback for random_get_entropy() instead of zero
nios2: use fallback for random_get_entropy() instead of zero
x86/tsc: Use fallback for random_get_entropy() instead of zero
um: use fallback for random_get_entropy() instead of zero
sparc: use fallback for random_get_entropy() instead of zero
xtensa: use fallback for random_get_entropy() instead of zero
random: insist on random_get_entropy() existing in order to simplify
random: do not use batches when !crng_ready()
random: use first 128 bits of input as fast init
random: do not pretend to handle premature next security model
random: order timer entropy functions below interrupt functions
random: do not use input pool from hard IRQs
random: help compiler out with fast_mix() by using simpler arguments
siphash: use one source of truth for siphash permutations
random: use symbolic constants for crng_init states
random: avoid initializing twice in credit race
random: move initialization out of reseeding hot path
random: remove ratelimiting for in-kernel unseeded randomness
random: use proper jiffies comparison macro
random: handle latent entropy and command line from random_init()
random: credit architectural init the exact amount
random: use static branch for crng_ready()
random: remove extern from functions in header
random: use proper return types on get_random_{int,long}_wait()
random: make consistent use of buf and len
random: move initialization functions out of hot pages
random: move randomize_page() into mm where it belongs
random: unify batched entropy implementations
random: convert to using fops->read_iter()
random: convert to using fops->write_iter()
random: wire up fops->splice_{read,write}_iter()
random: check for signals after page of pool writes
ACPI: sysfs: Fix BERT error region memory mapping
ALSA: ctxfi: Add SB046x PCI ID
