[PATCH openEuler-1.0-LTS] quota: flush quota_release_work upon quota writeback

[PATCH OLK-5.10] fs/dirty_pages: Add exclusive open lock to prevent null pointer dereference
by Zizhi Wo 15 Jan '25

15 Jan '25

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBHTNK -------------------------------- The current mechanism for printing dirty pages involves "/proc/dirty/buffer_size" and "/proc/dirty/dirty_list" being able to be opened simultaneously. If "buffer_size" is opened firstly and 1 is written to it, and then "dirty_list" is opened, followed by writing 0 to "buffer_size". Then variable "buf_dirty" will be freed and set to NULL. However, the user can still access "buf_dirty" through the already opened "dirty_list", which could lead to a NULL pointer dereference issue. To prevent the NULL pointer dereference problem, add an exclusive open lock. And now "/proc/dirty/buffer_size" and "/proc/dirty/dirty_list" cannot be opened at the same time unless "/proc/dirty/buffer_size" is opened in read-only mode. At the same time, "buff_used" and "buff_lock" in the original code are not needed, and the redundant code is deleted.
