[PATCH openEuler-1.0-LTS] dhugetlb: keep refcount to 0 while page is actually free in pool
by Liu Shixin 24 Dec '24

24 Dec '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBDF90 -------------------------------- While we split/merge page in dynamic pool, the refcount of page may be increased to 1 due to prep_new_page(), and we then set the refcount to 0. That means there's a time window that the refcount of the free page is not 0. split_huge_pages_set() will scan all pages and try to get the refcount If try to get refcount in the above time window and put_page() after the refcount is set to 0, the refcount will be decreased to -1. It's dangerous if the refcount for page is not 0 when split/merge, so try not to get refcount there.

[PATCH openEuler-1.0-LTS] ACPI: battery: Fix possible crash when unregistering a battery hook
by Heyuan Wang 24 Dec '24

24 Dec '24

From: Armin Wolf <W_Armin(a)gmx.de> stable inclusion from stable-v4.19.323 commit 76fb2cbf01571926da8ecf6876cc8cb07d3f5183 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBBN6V Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… ------------------------------------------------------------- [ Upstream commit 76959aff14a0012ad6b984ec7686d163deccdc16 ] When a battery hook returns an error when adding a new battery, then the battery hook is automatically unregistered. However the battery hook provider cannot know that, so it will later call battery_hook_unregister() on the already unregistered battery hook, resulting in a crash. Fix this by using the list head to mark already unregistered battery hooks as already being unregistered so that they can be ignored by battery_hook_unregister().
