* ceph: only send one flushsnap per cap_snap per mds sessionSage Weil2010-09-17
| | | | | | | | | | | Sending multiple flushsnap messages is problematic because we ignore the response if the tid doesn't match, and the server may only respond to each one once. It's also a waste. So, skip cap_snaps that are already on the flushing list, unless the caller tells us to resend (because we are reconnecting). Signed-off-by: Sage Weil <sage@newdream.net>
* ceph: fix cap_snap and realm splitSage Weil2010-09-16
| | | | | | | | | | | | | | The cap_snap creation/queueing relies on both the current i_head_snapc _and_ the i_snap_realm pointers being correct, so that the new cap_snap can properly reference the old context and the new i_head_snapc can be updated to reference the new snaprealm's context. To fix this, we: - move inodes completely to the new (split) realm so that i_snap_realm is correct, and - generate the new snapc's _before_ queueing the cap_snaps in ceph_update_snap_trace().

* ceph: stop sending FLUSHSNAPs when we hit a dirty capsnapSage Weil2010-09-14

* ceph: correctly set 'follows' in flushsnap messagesSage Weil2010-09-14
| | | | | | | | | The 'follows' should match the seq for the snap context for the given snap cap, which is the context under which we have been dirtying and writing data and metadata. The snapshot that _contains_ those updates thus _follows_ that context's seq #. Signed-off-by: Sage Weil <sage@newdream.net>
* ceph: fix dn offset during readdir_prepopulateSage Weil2010-09-13
| | | | | | | | | | | When adding the readdir results to the cache, ceph_set_dentry_offset was clobbered our just-set offset. This can cause the readdir result offsets to get out of sync with the server. Add an argument to the helper so that it does not. This bug was introduced by 1cd3935bedccf592d44343890251452a6dd74fc4.

* ceph: fix null pointer deref on anon root dentry releaseSage Weil2010-09-11
| | | | | | | | | | | | | | | | | | When we release a root dentry, particularly after a splice, the parent (actually our) inode was evaluating to NULL and was getting dereferenced by ceph_snap(). This is reproduced by something as simple as mount -t ceph monhost:/a/b mnt mount -t ceph monhost:/a mnt2 ls mnt2 A splice_dentry() would kill the old 'b' inode's root dentry, and we'd crash while releasing it. Fix by checking for both the ROOT and NULL cases explicitly. We only need to invalidate the parent dir when we have a correct parent to invalidate. Signed-off-by: Sage Weil <sage@newdream.net>

| * fsnotify: drop two useless bools in the fnsotify main loopEric Paris2010-08-27
| | | | | | | | | | | | | | | | | | The fsnotify main loop has 2 bools which indicated if we processed the inode or vfsmount mark in that particular pass through the loop. These bool can we replaced with the inode_group and vfsmount_group variables and actually make the code a little easier to understand. Signed-off-by: Eric Paris <eparis@redhat.com>
| * fsnotify: fix list walk orderEric Paris2010-08-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Marks were stored on the inode and vfsmonut mark list in order from highest memory address to lowest memory address. The code to walk those lists thought they were in order from lowest to highest with unpredictable results when trying to match up marks from each. It was possible that extra events would be sent to userspace when inode marks ignoring events wouldn't get matched with the vfsmount marks. This problem only affected fanotify when using both vfsmount and inode marks simultaneously. Signed-off-by: Eric Paris <eparis@redhat.com>

| * fanotify: flush outstanding perm requests on group destroyEric Paris2010-08-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an fanotify listener is closing it may cause a deadlock between the listener and the original task doing an fs operation. If the original task is waiting for a permissions response it will be holding the srcu lock. The listener cannot clean up and exit until after that srcu lock is syncronized. Thus deadlock. The fix introduced here is to stop accepting new permissions events when a listener is shutting down and to grant permission for all outstanding events. Thus the original task will eventually release the srcu lock and the listener can complete shutdown.

| * fsnotify: fix ignored mask handling between inode and vfsmount marksEric Paris2010-08-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The interesting 2 list lockstep walking didn't quite work out if the inode marks only had ignores and the vfsmount list requested events. The code to shortcut list traversal would not run the inode list since it didn't have real event requests. This code forces inode list traversal when a vfsmount mark matches the event type. Maybe we could add an i_fsnotify_ignored_mask field to struct inode to get the shortcut back, but it doesn't seem worth it to grow struct inode again. I bet with the recent changes to lock the way we do now it would actually not be a major perf hit to just drop i_fsnotify_mark_mask altogether. But that is for another day.

| * fsnotify: reset used_inode and used_vfsmount on each passEric Paris2010-08-22
| | | | | | | | | | | | | | | | | | | | The fsnotify main loop has 2 booleans which tell if a particular mark was sent to the listeners or if it should be processed in the next pass. The problem is that the booleans were not reset on each traversal of the loop. So marks could get skipped even when they were not sent to the notifiers.

| * fanotify: do not dereference inode_mark when it is unsetEric Paris2010-08-22
| | | | | | | | | | | | | | | | | | The fanotify code is supposed to get the group from the mark. It accidentally only used the inode_mark. If the vfsmount_mark was set but not the inode_mark it would deref the NULL inode_mark. Get the group from the correct place.
