fanotify: fix FAN_Q_OVERFLOW case of fanotify_read()

2012-11-18T19:30:00Z

If the FAN_Q_OVERFLOW bit set in event->mask, the fanotify event metadata will not contain a valid file descriptor, but copy_event_to_user() didn't check for that, and unconditionally does a fd_install() on the file descriptor. Which in turn will cause a BUG_ON() in __fd_install(). Introduced by commit 352e3b249284 ("fanotify: sanitize failure exits in copy_event_to_user()") Mea culpa - missed that path ;-/ Reported-by: Alex Shi Signed-off-by: Al Viro Signed-off-by: Linus Torvalds

fanotify: fix missing break

2012-11-09T05:41:47Z

Anders Blomdell noted in 2010 that Fanotify lost events and provided a test case. Eric Paris confirmed it was a bug and posted a fix to the list https://groups.google.com/forum/?fromgroups=#!topic/linux.kernel/RrJfTfyW2BE but never applied it. Repeated attempts over time to actually get him to apply it have never had a reply from anyone who has raised it So apply it anyway Signed-off-by: Alan Cox Reported-by: Anders Blomdell Cc: Eric Paris Cc: Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

fanotify: sanitize failure exits in copy_event_to_user()

2012-09-27T01:08:52Z

* do copy_to_user() before prepare_for_access_response(); that kills the need in remove_access_response(). * don't do fd_install() until we are past the last possible failure exit. Don't use sys_close() on cleanup side - just put_unused_fd() and fput(). Less racy that way... Signed-off-by: Al Viro

fsnotify: don't BUG in fsnotify_destroy_mark()

2012-01-15T02:01:42Z

Removing the parent of a watched file results in "kernel BUG at fs/notify/mark.c:139". To reproduce add "-w /tmp/audit/dir/watched_file" to audit.rules rm -rf /tmp/audit/dir This is caused by fsnotify_destroy_mark() being called without an extra reference taken by the caller. Reported by Francesco Cosoleto here: https://bugzilla.novell.com/show_bug.cgi?id=689860 Fix by removing the BUG_ON and adding a comment about not accessing mark after the iput.
