[PATCH openEuler-1.0-LTS] media: v4l2-tpg: prevent the risk of a division by zero
by Zhao Yipeng 04 Dec '24

04 Dec '24

From: Mauro Carvalho Chehab <mchehab+huawei(a)kernel.org> stable inclusion from stable-v4.19.324 commit e3c36d0bde309f690ed1f9cd5f7e63b3a513f94a category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB5ATB CVE: CVE-2024-50287 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=… -------------------------------- media: v4l2-tpg: prevent the risk of a division by zero commit e6a3ea83fbe15d4818d01804e904cbb0e64e543b upstream. As reported by Coverity, the logic at tpg_precalculate_line() blindly rescales the buffer even when scaled_witdh is equal to zero. If this ever happens, this will cause a division by zero. Instead, add a WARN_ON_ONCE() to trigger such cases and return without doing any precalculation.

[PATCH OLK-5.10] drivers/perf: hisi: Add support for HiSilicon DDRC v3 PMU driver
by Junhao He 04 Dec '24

04 Dec '24

driver inclusion category: featrue bugzilla: https://gitee.com/openeuler/kernel/issues/IARCNN -------------------------------- On HiSilicon HIP10C platform, the DDRC PMU is a v3 PMU. And only the offset of it's interrupt registers offset quite a different tune DDRC v2 PMUs. The control registeres and events code are the same as v2 PMU. Their modification was unexpected, which caused the interrupt handler to not handle counter overflows correctly (HiSilicon Erratum 162400501). The before DDRC PMU driver will probe v3 as v2. Therefore DDRC v3 interrupt handler cannot work properly. We fixed that by adding new ID HISI0235 to correct the DDRC v3 PMU interrupt register offset (including mask/status/clear registers).
