https://bugzilla.kernel.org/show_bug.cgi?id=215676 Bug ID: 215676 Summary: fanotify Ignoring/Excluding a Directory not working with FAN_MARK_MOUNT Product: File System Version: 2.5 Kernel Version: 5.11.0-27 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: ext4 Assignee: fs_ext4@xxxxxxxxxxxxxxxxxxxx Reporter: talkwithsrinivas@xxxxxxxxxxx Regression: No Created attachment 300557 --> https://bugzilla.kernel.org/attachment.cgi?id=300557&action=edit Test program to show directory exclusion not working If a process calls fanotify_mark(fd, FAN_MARK_ADD | FAN_MARK_MOUNT, FAN_OPEN_PERM, 0, "/mountpoint") no other directory exclusions can be applied. However a path (file) exclusion can still be applied using fanotify_mark(fd, FAN_MARK_ADD | FAN_MARK_IGNORED_MASK | FAN_MARK_IGNORED_SURV_MODIFY, FAN_OPEN_PERM | FAN_CLOSE_WRITE, AT_FDCWD, "/tmp/fio/abc"); ===> path exclusion that works. I think the directory exclusion not working is a bug as otherwise AV solutions cant exclude directories when using FAN_MARK_MOUNT. I believe the change should be simple since we are already supporting path exclusions. So we should be able to add the same for the directory inode. -- You may reply to this email to add a comment.
