[PATCH OLK-5.10] uprobes: check anon before compound when unregister
by Tengda Wu 02 Jul '25

02 Jul '25

From: Chen Zhongjin <chenzhongjin(a)huawei.com> hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ICJG91 -------------------------------- In uprobe unregister, if the old_page is a compound page, it will trigger a warning and cause the unregister operation to fail: "uprobe unregister should never work on compound page" If old_page is allocated by uprobe through alloc_page_vma(), this page cannot be compounded, so this warning means old_page is a remapped page after register. In this scenario, check PageAnon() first to determine whether the page is a remapped page. Just pass the PageCompound() check and unregister uprobe safely.

[PATCH OLK-6.6] drm/v3d: Add job to pending list if the reset was skipped
by GONG Ruiqi 02 Jul '25

02 Jul '25

From: Maíra Canal <mcanal(a)igalia.com> stable inclusion from stable-v6.6.91 commit 12125f7d9c15e6d8ac91d10373b2db2f17dcf767 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IC9933 CVE: CVE-2025-37951 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 35e4079bf1a2570abffce6ababa631afcf8ea0e5 upstream. When a CL/CSD job times out, we check if the GPU has made any progress since the last timeout. If so, instead of resetting the hardware, we skip the reset and let the timer get rearmed. This gives long-running jobs a chance to complete. However, when `timedout_job()` is called, the job in question is removed from the pending list, which means it won't be automatically freed through `free_job()`. Consequently, when we skip the reset and keep the job running, the job won't be freed when it finally completes. This situation leads to a memory leak, as exposed in [1] and [2]. Similarly to commit 704d3d60fec4 ("drm/etnaviv: don't block scheduler when GPU is still active"), this patch ensures the job is put back on the pending list when extending the timeout.
