Enhanced maintenance and test capability for pbha.
Enable ARM64_PBHA by default.
Changelog since v1:
- let {pte,pmd}_pbha return false if pbha is not enabled
Ma Wupeng (7):
proc: introduce proc_hide_ents to hide proc files
arm64: mm: Cleanup in pbha_bit0_pte_range
mm: cpufeature: Make update_pbha_perf_only_bit static
arm64: mm: Do not show info during startup if pbha is not enabled
arm64: mm: Hide pbha_bit0 in procfs if pbha is not enabled
arm64: mm: pagemap: Export pbha bit0 info
config: Enable ARM64_PBHA by default

[PATCH openEuler-1.0-LTS] hwrng: core - Fix page fault dead lock on mmap-ed hwrng
by Yi Yang 20 Mar '24
by Yi Yang 20 Mar '24

stable inclusion
from stable-v4.19.307
commit eafd83b92f6c044007a3591cbd476bcf90455990
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I99JR3
CVE: CVE-2023-52615
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
commit 78aafb3884f6bc6636efcc1760c891c8500b9922 upstream.
There is a dead-lock in the hwrng device read path. This triggers
when the user reads from /dev/hwrng into memory also mmap-ed from
/dev/hwrng. The resulting page fault triggers a recursive read
which then dead-locks.
Fix this by using a stack buffer when calling copy_to_user.

commit 78aafb3884f6bc6636efcc1760c891c8500b9922 upstream.
There is a dead-lock in the hwrng device read path. This triggers
when the user reads from /dev/hwrng into memory also mmap-ed from
/dev/hwrng. The resulting page fault triggers a recursive read
which then dead-locks.
Fix this by using a stack buffer when calling copy_to_user.
