At the time of pre-op, pre_op_xdata is populted with the xattrs we get from the disk and at the time of post-op it gets over-written without unreffing the previous value stored leading to a leak. This is a regression we missed in https://review.gluster.org/#/q/ba149bac92d169ae2256dbc75202dc9e5d06538e Originally: > Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> > (cherry picked from commit e7b79c59590c203c65f7ac8548b30d068c232d33) Change-Id: I0456f9ad6f77ce6248b747964a037193af3a3da7 Fixes: bz#1613512 Signed-off-by: Amar Tumballi <amarts@redhat.com>
If one of the paths given to _is_prefix is 0-length, then it is not a prefix of the other. Hence, _is_prefix should return false. Change-Id: I54aa577a64a58940ec91872d0d74dc19cff9106d BUG: 1599788 Signed-off-by: Kaushal M <kaushal@redhat.com>
Backport of https://review.gluster.org/#/c/20509/ BZ 1564071 complains of directories with missing gfid symlinks and corresponding "Found stale gfid handle" messages in the logs. Hence add a check to see if the symlink points to an actual directory before removing it. Note: Removing stale symlinks was added via commit 3e9a9c029fac359477fb26d9cc7803749ba038b2 Change-Id: I5d91fab8e5f3a621a9ecad4a1f9c898a3c2d346a BUG: 1603093 Signed-off-by: Ravishankar N <ravishankar@redhat.com>
Backport of: https://review.gluster.org/#/c/20029/ 3.12 still supports quorum-reads, hence modified afr_inode_refresh_done() to support that. If inode refresh failed on all children of afr due to ENOENT (say file migrated by dht), it resets the readables to zero. Any inflight txn which then later comes on the inode fails with EIO because no readable children present for the inode. Fix: Don't update readables when inode refresh fails on *all* children of afr. In that way any inflight txns will either proceed with its own inode refresh if needed and fail it with the right errno or use the old value of readables and continue with the txn. Also, add quorum checks to the beginning of afr_transaction(). Otherwise, we seem to be winding the lock and checking for quorum only in pre-op pahse. Note: This should ideally fix BZ 1329505 since the stop gap fix for it is has been reverted at https://review.gluster.org/#/c/20028.

Backport of https://review.gluster.org/#/c/20271/ (only change is in .t) commit 20fa80057eb430fd72b4fa31b9b65598b8ec1265 introduced a regression wherein if a file is present in only 1 brick of replica *and* doesn't have a gfid associated with it, it doesn't get healed upon the next lookup from the client. Fix it.

Backport of https://review.gluster.org/#/c/20036/ Note: We need to update inode context's write_subvol even in case of compound fops. This is not there in master and 4.1 since compound FOPS was removed in it. Problem: In the .t, when the only good brick was brought down, writes on the fd were still succeeding on the bad bricks. The inflight split-brain check was marking the write as failure but since the write succeeded on all the bad bricks, afr_txn_nothing_failed() was set to true and we were unwinding writev with success to DHT and then catching the failure in post-op in the background. Fix: Don't wind the FOP phase if the write_subvol (which is populated with readable subvols obtained in pre-op cbk) does not have at least 1 good brick which was up when the transaction started.

Backport of https://review.gluster.org/#/c/19781/ Problem: We seem to be winding the FOP if pre-op did not succeed on quorum bricks and then failing the FOP with EROFS since the fop did not meet quorum. This essentially masks the actual error due to which pre-op failed. (See BZ). Fix: Skip FOP phase if pre-op quorum is not met and go to post-op.

If the post-op phase of txn did not meet quorm checks, use that errno to unwind the FOP rather than blindly setting ENOTCONN.

afr relies on pending changelog xattrs to identify source and sinks and the setting of these xattrs happen in post-op. So if post-op fails, we need to unwind the write txn with a failure.
