* glusterd: Fix management encryption issues with GlusterDv3.6.4Kaushal M2015-07-132-8/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of commit 01b82c6 from master Management encryption was enabled incorrectly in GlusterD leading to issues of cluster deadlocks. This has been fixed with this commit. The fix is in two parts, 1. Correctly enable encrytion for the TCP listener in GlusterD and re-enable own-threads for encrypted connections. Without this, GlusterD could try to esatblish the blocking SSL connects in the epoll thread, for eg. when handling friend updates, which could lead to cluster deadlocks. 2. Explicitly enable encryption for outgoing peer connections. Without enabling encryption explicitly for outgoing connections was causing SSL socket events to be handled in the epoll thread. Some events, like disconnects during peer detach, could lead to connection attempts to happen in the epoll thread, leading to deadlocks again.

| | | | | | | | | | | | | | | | | | | | | failed on src Backport of: http://review.gluster.org/11119 Test bug-948686.t was causing shd to dump core due to gfid being NULL. This was due to the volume being stopped while index heal's in progress, causing afr_selfheal_unlocked_lookup_on() to fail sometimes on the src brick with ENOTCONN. And when afr_selfheal_newentry_mark() copies the gfid off the src iatt, it essentially copies null gfid. This was causing the assertion as part of xattrop in protocol/client to fail.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | read-subvol-entry.t tests that if a brick has pending operations, it is not used for readdir operations. On NetBSD this test exhibits spurious failures, with the wrong brick being used to perform readdir. It happens because when afr_replies_interpret() looks at xattr for pending attributes, it uses alternative bahvior whether it is working on a directory or another object. The decision is based on inode->ia_type, which may be IA_INVAL at that time if we come there from: afr_replies_interpret.() afr_xattrs_are_equal() afr_lookup_metadata_heal_chec() afr_lookup_entry_heal() afr_lookup_cbk() Using replies[i].poststat.ia_type, which is correctly set, works around the problem.

* cluster/dht: Unwind with proper op_retRaghavendra Talur2015-05-041-12/+86
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Expected behavior of get_real_filename feature. A getxattr on a existing dir with glusterfs.get_real_filename:<filename> as key should result in one of the following things. a. A value returned for that key having the real filename (a file whose match is a case insensitive match to the filename passed in key). b. op_ret = -1 and errno set to ENOENT meaning that no such file exists under the specified dir in any case. c. op_ret = -1 and errno set to ENODATA. This is a case assuming no xlator interprets the glusterfs.get_real_filename key and it get passed down to the posix xlator. Naturally, posix xlator would not find any xattr with this key and would return ENODATA. This will be interpreted specially by the caller as the feature not being supported by underlying glusterfs. 2. What assumptions are wrong? Initially the key used to be user.glusterfs.get_real_filename. In that case, when posix xlator did a getxattr call it would have received ENODATA as error. However, the key has now changed to glusterfs.get_real_filename. This leads to a EOPNOTSUPP error instead. Considering the above information, this is a rewrite of get_real_filename logic in dht.

Non-blocking locks also need to be serialized. Otherwise there is a chance that both the mounts which issued same non-blocking inodelk may endup not acquiring the lock on any-brick. Ex: Mount1 and Mount2 request for full length lock on file f1. Mount1 afr may acquire the partial lock on brick-1 and may not acquire the lock on brick-2 because Mount2 already got the lock on brick-2, vice versa. Since both the mounts only got partial locks, afr treats them as failure in gaining the locks and unwinds with EAGAIN errno.

* afr: stop encoding subvolume id in readdir d_offAnand Avati2015-03-033-131/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of http://review.gluster.org/9332 The purpose of encoding d_off in AFR is to indicate the selected subvolume for the first readdir, and continue all further readdirs of the session on the same subvolume. This is required because, unlike files, dir d_offs are specific to the backend and cannot be re-used on another subvolume. The d_off transformation encodes the subvolume id and prevents such invalid use of d_offs on other servers. However, this approach could be quite wasteful of precious d_off bit-space. Unlike DHT, where server id can change from entry to entry and thus encoding the server id in the transformed d_off is necessary, we could take a slightly relaxed approach in AFR. The approach is to save the subvolume where the last readdir request was sent in the fd_ctx. This consumes constant space (i.e no per-entry cache), and serves the purpose of avoiding d_off "misuse" (i.e using d_off from one server on another). The compromise here is NFS resuming readdir from a non-0 cookie after an extended delay (either anonymous FD has been reclaimed, or server has restarted). In such cases a subvolume is picked freshly. To make this fresh picking more deterministic (i.e, to pick the same subvolume whenever possible, even after reboots), the function afr_hash_child (used by afr_read_subvol_select_by_policy) is modified to skip all dynamic inputs (i.e PID) for the case of directories.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glusterd op-sm infrastructure has some loophole in handing error cases in locking/unlocking phases which ends up having stale locks restricting further transactions to go through. This patch still doesn't handle all possible unlocking error cases as the framework neither has retry mechanism nor the lock timeout. For eg - if unlocking fails in one of the peer, cluster wide lock is not released and further transaction can not be made until and unless originator node/the node where unlocking failed is restarted. Following test cases were executed (with the help of gdb) after applying this patch: * RPC timesout in lock cbk * Decoding of RPC response in lock cbk fails * RPC response is received from unknown peer in lock cbk * Setting peerinfo in dictionary fails while sending lock request for first peer in the list * Setting peerinfo in dictionary fails while sending lock request for other peers * Lock RPC could not be sent for peers For all above test cases the success criteria is not to have any stale locks Patch link : http://review.gluster.org/9012 Change-Id: Ia1550341c31005c7850ee1b2697161c9ca04b01a BUG: 1179136 Signed-off-by: Atin Mukherjee <amukherj@redhat.com> Reviewed-on: http://review.gluster.org/9012 Reviewed-by: Krishnan Parthasarathi <kparthas@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Kaushal M <kaushal@redhat.com> Reviewed-on: http://review.gluster.org/9393 Reviewed-by: Raghavendra Bhat <raghavendra@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In current implementation xaction_peers list is maintained in a global variable (glustrd_priv_t) for syncop/mgmt_v3. This means consistency and atomicity of peerinfo list across transactions is not guranteed when multiple syncop/mgmt_v3 transaction are going through. We had got into a problem in mgmt_v3-locks.t which was failing spuriously, the reason for that was two volume set operations (in two different volume) was going through simultaneouly and both of these transaction were manipulating the same xaction_peers structure which lead to a corrupted list. Because of which in some cases unlock request to peer was never triggered and we end up with having stale locks. Solution is to maintain a per transaction local xaction_peers list for every syncop. Please note I've identified this problem in op-sm area as well and a separate patch will be attempted to fix it.

| | | | | | | | | | | | | | | | | | | | | | | When command 'clear-locks' from cli is executed, a getxattr request is received by ec. This request was handled as usual, first locking the inode. Once this request was processed by the bricks, all locks were removed, including the lock used by ec. When ec tried to unlock the previously acquired lock (which was already released), caused a crash in glusterfsd. This fix executes the getxattr request without any lock acquired for the clear-locks command.

* ec: Fix posix compliance failuresXavier Hernandez2015-02-116-87/+101
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch solves some problems that caused dispersed volumes to not pass posix smoke tests: * Problems in open/create with O_WRONLY Opening files with -w- permissions using O_WRONLY returned an EACCES error because internally O_WRONLY was replaced with O_RDWR. * Problems with entrylk on renames. When source and destination were the same, ec tried to acquire the same entrylk twice, causing a deadlock. * Overwrite of a variable when reordering locks. On a rename, if the second lock needed to be placed at the beggining of the list, the 'lock' variable was overwritten and later its timer was cancelled, cancelling the incorrect one. * Handle O_TRUNC in open. When O_TRUNC was received in an open call, it was blindly propagated to child subvolumes. This caused a discrepancy between real file size and the size stored into trusted.ec.size xattr. This has been solved by removing O_TRUNC from open and later calling ftruncate.

* ec: Fix failures with missing filesXavier Hernandez2015-02-112-102/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When a file does not exist on a brick but it does on others, there could be problems trying to access it because there was some loc_t structures with null 'pargfid' but 'name' was set. This forced inode resolution based on <pargfid>/name instead of <gfid> which would be the correct one. To solve this problem, 'name' is always set to NULL when 'pargfid' is not present. Another problem was caused by an incorrect management of errors while doing incremental locking. The only allowed error during an incremental locking was ENOTCONN, but missing files on a brick can be returned as ESTALE. This caused an EIO on the operation. This patch doesn't care of errors during an incremental locking. At the end of the operation it will check if there are enough successfully locked bricks to continue or not.
