[PATCH OLK-6.6] sched/core: Disable page allocation in task_tick_mm_cid()
by Zheng Zucheng 05 Dec '24

05 Dec '24

From: Waiman Long <longman(a)redhat.com> stable inclusion from stable-v6.6.59 commit 509c29d0d26f68a6f6d0a05cb1a89725237e2b87 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB2STY CVE: CVE-2024-50140 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 73ab05aa46b02d96509cb029a8d04fca7bbde8c7 ] With KASAN and PREEMPT_RT enabled, calling task_work_add() in task_tick_mm_cid() may cause the following splat. [ 63.696416] BUG: sleeping function called from invalid context at kernel/locking/spinlock_rt.c:48 [ 63.696416] in_atomic(): 1, irqs_disabled(): 1, non_block: 0, pid: 610, name: modprobe [ 63.696416] preempt_count: 10001, expected: 0 [ 63.696416] RCU nest depth: 1, expected: 1 This problem is caused by the following call trace. sched_tick() [ acquire rq->__lock ] -> task_tick_mm_cid() -> task_work_add() -> __kasan_record_aux_stack() -> kasan_save_stack() -> stack_depot_save_flags() -> alloc_pages_mpol_noprof() -> __alloc_pages_noprof() -> get_page_from_freelist() -> rmqueue() -> rmqueue_pcplist() -> __rmqueue_pcplist() -> rmqueue_bulk() -> rt_spin_lock() The rq lock is a raw_spinlock_t. We can't sleep while holding it. IOW, we can't call alloc_pages() in stack_depot_save_flags(). The task_tick_mm_cid() function with its task_work_add() call was introduced by commit 223baf9d17f2 ("sched: Fix performance regression introduced by mm_cid") in v6.4 kernel. Fortunately, there is a kasan_record_aux_stack_noalloc() variant that calls stack_depot_save_flags() while not allowing it to allocate new pages. To allow task_tick_mm_cid() to use task_work without page allocation, a new TWAF_NO_ALLOC flag is added to enable calling kasan_record_aux_stack_noalloc() instead of kasan_record_aux_stack() if set. The task_tick_mm_cid() function is modified to add this new flag. The possible downside is the missing stack trace in a KASAN report due to new page allocation required when task_work_add_noallloc() is called which should be rare.

[PATCH OLK-5.10 v2] drivers/perf: hisi: Add support for HiSilicon DDRC v3 PMU driver
by Junhao He 05 Dec '24

05 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).

[PATCH openEuler-1.0-LTS] usb: typec: altmode should keep reference to parent
by Zhang Zekun 05 Dec '24

05 Dec '24

From: Thadeu Lima de Souza Cascardo <cascardo(a)igalia.com> stable inclusion from stable-v4.19.323 commit 2b0b33e8a58388fa9078f0fbe9af1900e6b08879 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB2SU4 CVE: CVE-2024-50150 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… ------------------------------------------------------------- [ Upstream commit befab3a278c59db0cc88c8799638064f6d3fd6f8 ] The altmode device release refers to its parent device, but without keeping a reference to it. When registering the altmode, get a reference to the parent and put it in the release function.

[PATCH openEuler-1.0-LTS] media: v4l2-tpg: prevent the risk of a division by zero

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).
