[PATCH] fanotify: fix merging marks masks with FAN_ONDIR
by Yang Yingliang 10 Dec '20

10 Dec '20

From: Amir Goldstein <amir73il(a)gmail.com> mainline inclusion from mainline-5.7-rc1 commit 55bf882c7f13dda8bbe624040c6d5b4fbb812d16 category: bugfix bugzilla: 46764 CVE: NA https://gitee.com/openeuler/kernel/issues/I27PTB?from=project-issue --------------------------- Change the logic of FAN_ONDIR in two ways that are similar to the logic of FAN_EVENT_ON_CHILD, that was fixed in commit 54a307ba8d3c ("fanotify: fix logic of events on child"): 1. The flag is meaningless in ignore mask 2. The flag refers only to events in the mask of the mark where it is set This is what the fanotify_mark.2 man page says about FAN_ONDIR: "Without this flag, only events for files are created." It doesn't say anything about setting this flag in ignore mask to stop getting events on directories nor can I think of any setup where this capability would be useful. Currently, when marks masks are merged, the FAN_ONDIR flag set in one mark affects the events that are set in another mark's mask and this behavior causes unexpected results. For example, a user adds a mark on a directory with mask FAN_ATTRIB | FAN_ONDIR and a mount mark with mask FAN_OPEN (without FAN_ONDIR). An opendir() of that directory (which is inside that mount) generates a FAN_OPEN event even though neither of the marks requested to get open events on directories.

by Yang Yingliang 08 Dec '20

08 Dec '20

From: Tang Yizhou <tangyizhou(a)huawei.com> ascend inclusion category: bugfix bugzilla: NA CVE: NA ------------------------------------------------- 1. Error handling of sp_free(). 2. When sp_alloc(..., SP_HUGEPAGE, ...) rollbacks to normal page, we need to call vfs_fallocate() otherwise memory leaks until sp group is dead. 3. When sp_alloc(..., SP_HUGEPAGE, ...) rollbacks to normal page, we need to clear SP_HUGEPAGE bit in sp_flags then spa_stat interface will show the spa as a normal page spa correctly. 4. Add the reference count of a spg in find_or_alloc_sp_group() due to closer relationship.
