ceph: use complete_all and wake_up_all

2010-07-27T20:11:17Z

This fixes an issue triggered by running concurrent syncs. One of the syncs would go through while the other would just hang indefinitely. In any case, we never actually want to wake a single waiter, so the *_all functions should be used. Signed-off-by: Yehuda Sadeh Signed-off-by: Sage Weil

ceph: fix dentry lease release

2010-07-23T20:54:21Z

When we embed a dentry lease release notification in a request, invalidate our lease so we don't think we still have it. Otherwise we can get all sorts of incorrect client behavior when multiple clients are interacting with the same part of the namespace. Signed-off-by: Sage Weil

ceph: fix leak of dentry in ceph_init_dentry() error path

2010-07-23T17:02:07Z

If we fail to allocate a ceph_dentry_info, don't leak the dn reference. Signed-off-by: Sage Weil

ceph: fix pg_mapping leak on pg_temp updates

2010-07-23T17:02:06Z

Free the ceph_pg_mapping structs when they are removed from the pg_temp rbtree. Also fix a leak in the __insert_pg_mapping() error path. Signed-off-by: Sage Weil

ceph: fix d_release dop for snapdir, snapped dentries

2010-07-23T17:02:05Z

We need to set the d_release dop for snapdir and snapped dentries so that the ceph_dentry_info struct gets released. We also use the dcache to cache readdir results when possible, which only works if we know when dentries are dropped from the cache. Since we don't use the dcache for readdir in the hidden snapdir, avoid that case in ceph_dentry_release. Signed-off-by: Sage Weil

ceph: avoid dcache readdir for snapdir

2010-07-22T20:50:45Z

We should always go to the MDS for readdir on the hidden snapdir. The set of snapshots can change at any time; the client can't trust its cache for that. Signed-off-by: Sage Weil

ceph: do not include cap/dentry releases in replayed messages

2010-07-16T17:30:18Z

Strip the cap and dentry releases from replayed messages. They can cause the shared state to get out of sync because they were generated (with the request message) earlier, and no longer reflect the current client state. Signed-off-by: Sage Weil

ceph: reuse request message when replaying against recovering mds

2010-07-16T17:30:17Z

Replayed rename operations (after an mds failure/recovery) were broken because the request paths were regenerated from the dentry names, which get mangled when d_move() is called. Instead, resend the previous request message when replaying completed operations. Just make sure the REPLAY flag is set and the target ino is filled in. This fixes problems with workloads doing renames when the MDS restarts, where the rename operation appears to succeed, but on mds restart then fails (leading to client confusion, app breakage, etc.).

ceph: fix creation of ipv6 sockets

2010-07-09T22:00:20Z

Use the address family from the peer address instead of assuming IPv4. Signed-off-by: Sage Weil
