From 66ba93c0d7fe63def447ad0afe380307ff9ebcad Mon Sep 17 00:00:00 2001 From: Lino Sanfilippo Date: Tue, 10 Feb 2015 14:08:27 -0800 Subject: [PATCH] fanotify: don't set FAN_ONDIR implicitly on a marks ignored mask Currently FAN_ONDIR is always set on a mark's ignored mask when the event mask is extended without FAN_MARK_ONDIR being set. This may result in events for directories being ignored unexpectedly for call sequences like fanotify_mark(fd, FAN_MARK_ADD, FAN_OPEN | FAN_ONDIR , AT_FDCWD, "dir"); fanotify_mark(fd, FAN_MARK_ADD, FAN_CLOSE, AT_FDCWD, "dir"); Also FAN_MARK_ONDIR is only honored when adding events to a mark's mask, but not for event removal. Fix both issues by not setting FAN_ONDIR implicitly on the ignore mask any more. Instead treat FAN_ONDIR as any other event flag and require FAN_MARK_ONDIR to be set by the user for both event mask and ignore mask. Furthermore take FAN_MARK_ONDIR into account when set for event removal.
