[PATCH OLK-6.6 V1] media: dvbdev: fix the logic when DVB_DYNAMIC_MINORS is not set
by Zicheng Qu 28 Nov '24

28 Nov '24

From: Mauro Carvalho Chehab <mchehab+huawei(a)kernel.org> stable inclusion from stable-v6.6.63 commit db12e874e1a202206c734d89920e4aa9e290efa2 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB5KR8 CVE: CVE-2024-53063 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit a4aebaf6e6efff548b01a3dc49b4b9074751c15b upstream. When CONFIG_DVB_DYNAMIC_MINORS, ret is not initialized, and a semaphore is left at the wrong state, in case of errors. Make the code simpler and avoid mistakes by having just one error check logic used weather DVB_DYNAMIC_MINORS is used or not.

[PATCH OLK-5.10] arm64: mm: Stop use spinlock during pbha early init
by Wupeng Ma 28 Nov '24

28 Nov '24

From: Ma Wupeng <mawupeng1(a)huawei.com> hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I96IZH -------------------------------- During early_pbha_init() in __primary_switched(), debug spinlock related function is not fully initialized. This will lead to kernel unable to boot with CONFIG_LOCK_STAT=y or related configs. Since kernel is running with only one cpu during startup, there is no need to use lock.
