* more conservative S_NOSEC handlingAl Viro2011-06-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | Caching "we have already removed suid/caps" was overenthusiastic as merged. On network filesystems we might have had suid/caps set on another client, silently picked by this client on revalidate, all of that *without* clearing the S_NOSEC flag. AFAICS, the only reasonably sane way to deal with that is * new superblock flag; unless set, S_NOSEC is not going to be set. * local block filesystems set it in their ->mount() (more accurately, mount_bdev() does, so does btrfs ->mount(), users of mount_bdev() other than local block ones clear it) * if any network filesystem (or a cluster one) wants to use S_NOSEC, it'll need to set MS_NOSEC in sb->s_flags *AND* take care to clear S_NOSEC when inode attribute changes are picked from other clients. It's not an earth-shattering hole (anybody that can set suid on another client will almost certainly be able to write to the file before doing that anyway), but it's a bug that needs fixing.

| * | ocfs2/dlm: Do not migrate resource to a node that is leaving the domainSunil Mushran2011-05-252-95/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During dlm domain shutdown, o2dlm has to free all the lock resources. Ones that have no locks and references are freed. Ones that have locks and/or references are migrated to another node. The first task in migration is finding a target. Currently we scan the lock resource and find one node that either has a lock or a reference. This is not very efficient in a parallel umount case as we might end up migrating the lock resource to a node which itself may have to migrate it to a third node. The patch scans the dlm->exit_domain_map to ensure the target node is not leaving the domain. If no valid target node is found, o2dlm does not migrate the resource but instead waits for the unlock and deref messages that will allow it to free the resource.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new dlm message DLM_BEGIN_EXIT_DOMAIN_MSG and ups the dlm protocol to 1.2. o2dlm sends this new message in dlm_unregister_domain() to mark the beginning of the exit domain. This message is sent to all nodes in the domain. Currently o2dlm has no way of informing other nodes of its impending exit. This information is useful as the other nodes could disregard the exiting node in certain operations. For example, in resource migration. If two or more nodes were umounting in parallel, it would be more efficient if o2dlm were to choose a non-exiting node to be the new master node rather than an exiting one.

* | | ocfs2/dlm: Target node death during resource migration leads to thread spinSunil Mushran2011-05-131-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | During resource migration, if the target node were to die, the thread doing the migration spins until the target node is not removed from the domain map. This patch slows the spin by making the thread wait for the recovery to kick in. Signed-off-by: Sunil Mushran <sunil.mushran@oracle.com> Signed-off-by: Joel Becker <jlbec@evilplan.org>

* | | ocfs2/cluster: Heartbeat mismatch message improvedSunil Mushran2011-05-131-17/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If o2hb finds unexpected values in the heartbeat slot, it prints a message "ERROR: Device "dm-6": another node is heartbeating in our slot!" This message could be misleading. This patch adds two more messages to help users better diagnose the problem.

* | | ocfs2/cluster: Increase the live threshold for global heartbeatSunil Mushran2011-05-131-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have seen isolated cases (very few, I might add) of o2hb not detecting all live nodes on startup. One plausible reasoning for it is that other node had a hb io delay at the same time. The live threshold set at 2 (as low as it can be) could be increased to ameliorate the situation. But increasing the threshold directly affects mount time. Currently it takes around 5 secs to mount a volume in o2cb cluster with local heartbeat. Increasing the threshold will make mounts even slower. As the issue itself is rare, we have left things as they are for the local heartbeat mode. However we can improve the situation for global heartbeat mode as in that mode, we start the heartbeat much before the mount. This patch doubles the live threshold for the start of the first region in global heartbeat mode. Addresses internal Oracle bug#10635585.
