* afr: capture the correct errno in post-op quorum checkrelease-3.13Ravishankar N2018-02-061-8/+8
| | | | | | | | | | If the post-op phase of txn did not meet quorm checks, use that errno to unwind the FOP rather than blindly setting ENOTCONN. Change-Id: I0cb0c8771ec75a45f9a25ad4cd8601103deddf0c BUG: 1536346 Signed-off-by: Ravishankar N <ravishankar@redhat.com> (cherry picked from commit 440a048f24b006c80af3d7bcd0a1f13fe3459d87)
* afr: don't treat all cases all bricks being blamed as split-brainRavishankar N2018-02-062-9/+48
| | | | | | | | | | | | | | | | | | | | | | | | Problem: We currently don't have a roll-back/undoing of post-ops if quorum is not met. Though the FOP is still unwound with failure, the xattrs remain on the disk. Due to these partial post-ops and partial heals (healing only when 2 bricks are up), we can end up in split-brain purely from the afr xattrs point of view i.e each brick is blamed by atleast one of the others. These scenarios are hit when there is frequent connect/disconnect of the client/shd to the bricks while I/O or heal are in progress. Fix: Instead of undoing the post-op, pick a source based on the xattr values. If 2 bricks blame one, the blamed one must be treated as sink. If there is no majority, all are sources. Once we pick a source, self-heal will then do the heal instead of erroring out due to split-brain.

* cluster/afr: remove unnecessary child_up initializationXavier Hernandez2018-02-051-7/+0
| | | | | | | | | | | | | | | The child_up array was initialized with all elements being -1 to allow afr_notify() to differentiate down bricks from bricks that haven't reported yet. With current implementation this is not needed anymore and it was causing unexpected results when other parts of the code considered that if child_up[i] != 0, it meant that it was up.

* afr: add quorum checks in post-opRavishankar N2018-02-011-0/+29
| | | | | | | | | | | 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.

* cluster/afr: Adding option to take full file lockkarthik-us2018-01-194-3/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: In replica 3 volumes there is a possibilities of ending up in split brain scenario, when multiple clients writing data on the same file at non overlapping regions in parallel. Scenario: - Initially all the copies are good and all the clients gets the value of data readables as all good. - Client C0 performs write W1 which fails on brick B0 and succeeds on other two bricks. - C1 performs write W2 which fails on B1 and succeeds on other two bricks. - C2 performs write W3 which fails on B2 and succeeds on other two bricks. - All the 3 writes above happen in parallel and fall on different ranges so afr takes granular locks and all the writes are performed in parallel. Since each client had data-readables as good, it does not see file going into split-brain in the in_flight_split_brain check, hence performs the post-op marking the pending xattrs. Now all the bricks are being blamed by each other, ending up in split-brain. Fix: Have an option to take either full lock or range lock on files while doing data transactions, to prevent the possibility of ending up in split brains. With this change, by default the files will take full lock while doing IO. If you want to make use of the old range lock change the value of "cluster.full-lock" to "no".

* cluster/afr: Fixing the flaws in arbiter becoming source patchkarthik-us2018-01-187-180/+277
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Setting the write_subvol value to read_subvol in case of metadata transaction during pre-op (commit 19f9bcff4aada589d4321356c2670ed283f02c03) might lead to the original problem of arbiter becoming source. Scenario: 1) All bricks are up and good 2) 2 writes w1 and w2 are in progress in parallel 3) ctx->read_subvol is good for all the subvolumes 4) w1 succeeds on brick0 and fails on brick1, yet to do post-op on the disk 5) read/lookup comes on the same file and refreshes read_subvols back to all good 6) metadata transaction happens which makes ctx->write_subvol to be assigned with ctx->read_subvol which is all good 7) w2 succeeds on brick1 and fails on brick0 and this will update the brick in reverse order leading to arbiter becoming source Fix: Instead of setting the ctx->write_subvol to ctx->read_subvol in the pre-op statge, if there is a metadata transaction, check in the function __afr_set_in_flight_sb_status() if it is a data/metadata transaction. Use the value of ctx->write_subvol if it is a data transactions and ctx->read_subvol value for other transactions. With this patch we assign the value of ctx->write_subvol in the afr_transaction_perform_fop() with the on disk value, instead of assigning it in the afr_changelog_pre_op() with the in memory value.

* mount/fuse: use fstat in getattr implementation if any opened fd is availableRaghavendra G2018-01-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The restriction of using fds opened by the same Pid means fds cannot be shared across threads of multithreaded application. Note that fops from kernel have different Pid for different threads. Imagine following sequence of operations: * Turn off performance.open-behind * Thread t1 opens an fd - fd1 - on file "file". Let's assume nodeid of "file" is "nodeid-file". * Thread t2 does RENAME ("newfile", "file"). Let's assume nodeid of "newfile" as "nodeid-newfile". * t2 proceeds to do fstat (fd1) The above set of operations can sometimes result in ESTALE/ENOENT errors. RENAME overwrites "file" with "newfile" changing its nodeid from "nodeid-file" to "nodeid-newfile" and post RENAME, "nodeid-file" is removed from the backend. If fstat carries nodeid-file as argument, which can happen if lookup has not refreshed the nodeid of "file" and since t2 doesn't have an fd opened, fuse_getattr_resume uses STAT which will fail as "nodeid-file" no longer exists. Since the above set of operations and sharing of fds across multiple threads are valid, this is a bug. The fix is to use any fd opened on the inode. In this specific example fuse_getattr_resume will find fd1 and winds down the call as fstat (fd1) which won't fail. Cross-checked with "Miklos Szeredi" <mszeredi.at.redhat.dot.com> for any security issues with this solution and he approves the solution. Thanks to "Miklos Szeredi" <mszeredi.at.redhat.dot.com> for all the pointers and discussions. >Change-Id: I88dd29b3607cd2594eee9d72a1637b5346c8d49c >BUG: 1510401 >Signed-off-by: Raghavendra G <rgowdapp@redhat.com> (cherry picked from commit 8b57378e5596f287a7b9d106dd6fb56a624b42ee) Change-Id: I88dd29b3607cd2594eee9d72a1637b5346c8d49c BUG: 1529084 Signed-off-by: Raghavendra G <rgowdapp@redhat.com>

* performance/write-behind: fix bug while handling short writesRaghavendra G2017-12-261-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The variabled "fulfilled" in wb_fulfill_short_write is not reset to 0 while handling every member of the list. This has some interesting consequences: * If we break from the loop while processing last member of the list head->winds, req is reset to head as the list is a circular one. However, head is already fulfilled and can potentially be freed. So, we end up adding a freed request to wb_inode->todo list. This is the RCA for the crash tracked by the bug associated with this patch (Note that we saw "holder" which is freed in todo list). * If we break from the loop while processing any of the last but one member of the list head->winds, req is set to next member in the list, skipping the current request, even though it is not entirely synced. This can lead to data corruption. The fix is very simple and we've to change the code to make sure "fulfilled" reflects whether the current request is fulfilled or not and it doesn't carry history of previous requests in the list. >Change-Id: Ia3d6988175a51c9e08efdb521a7b7938b01f93c8 >BUG: 1528558 >Signed-off-by: Raghavendra G <rgowdapp@redhat.com> (cherry picked from commit 0bc22bef7f3c24663aadfb3548b348aa121e3047) Change-Id: Ia3d6988175a51c9e08efdb521a7b7938b01f93c8 BUG: 1529094 Signed-off-by: Raghavendra G <rgowdapp@redhat.com>

* feature/bitrot: remove internal xattrs from lookup cbkRavishankar N2017-12-192-7/+21
| | | | | | | | | | | | | | | | | | | | | | Problem: afr requests all xattrs in lookup via the list-xattr key. If bitrot is enabled and later disabled, or if the bitrot xattrs were present due to an older version of bitrot which used to create the xattrs without enabling the feature, the xattrs (trusted.bit-rot.version in particular) was not getting filtered and ended up reaching the client stack. AFR, on noticing different values of the xattr across bricks of the replica, started triggering spurious metadata heals. Fix: Filter all internal xattrs in bitrot xlator before unwinding lookup, (f)getxattr. Thanks to Kotresh for the help in RCA'ing.

| | | | | | | | | | | | | | | | | | | | | | | | | Superflous dentries that cannot be fit in the buffer size provided by kernel are thrown away by fuse-bridge. This means, * the next readdir(p) seen by readdir-ahead would have an offset of a dentry returned in a previous readdir(p) response. When readdir-ahead detects non-monotonic offset it turns itself off which can result in poor readdir performance. * readdirp can be cpu-intensive on brick and there is no point to read all those dentries just to be thrown away by fuse-bridge. So, the best strategy would be to fill the buffer optimally - neither overfill nor underfill. >Change-Id: Idb3d85dd4c08fdc4526b2df801d49e69e439ba84 >BUG: 1492625 >Signed-off-by: Raghavendra G <rgowdapp@redhat.com> (cherry picked from commit e785faead91f74dce7c832848f2e8f3f43bd0be5) Change-Id: Idb3d85dd4c08fdc4526b2df801d49e69e439ba84 BUG: 1522710 Signed-off-by: Raghavendra G <rgowdapp@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: When eager-lock is on, and two writes happen in parallel on a FD we were observing the following behaviour: - First write fails on one data brick - Since the post-op is not yet happened, the inode refresh will get both the data bricks as readable and set it in the inode context - In flight split brain check see both the data bricks as readable and allows the second write - Second write fails on the other data brick - Now the post-op happens and marks both the data bricks as bad and arbiter will become source for healing Fix: Adding one more variable called write_suvol in inode context and it will have the in memory representation of the writable subvols. Inode refresh will not update this value and its lifetime is pre-op through unlock in the afr transaction. Initially the pre-op will set this value same as read_subvol in inode context and then in the in flight split brain check we will use this value instead of read_subvol. After all the checks we will update the value of this and set the read_subvol same as this to avoid having incorrect value in that.

| | | | | | | | | | | | | | | | | | | | | | | Problem: In an arbiter volume, lookup was being served from one of the sink bricks (source brick was down). shard uses the iatt values from lookup cbk to calculate the size and block count, which in this case were incorrect values. shard_local_t->last_block was thus initialised to -1, resulting in an infinite while loop in shard_common_resolve_shards(). Fix: Use client quorum logic to allow or fail the lookups from afr if there are no readable subvolumes. So in replica-3 or arbiter vols, if there is no good copy or if quorum is not met, fail lookup with ENOTCONN. With this fix, we are also removing support for quorum-reads xlator option. So if quorum is not met, neither read nor write txns are allowed and we fail the fop with ENOTCONN.

| | | | | | | | | | | | | | | | The trusted.SGI_ACL_FILE appears to set posix ACLs on the linkto file that is a target of file migration. This can mess up file permissions and cause linkto identification to fail. Now we remove all ACL xattrs from the results of the listxattr call on the source before setting them on the target. > BUG: 1514329 > Signed-off-by: N Balachandran <nbalacha@redhat.com> Change-Id: I56802dbaed783a16e3fb90f59f4ce849f8a4a9b4 BUG: 1515045 Signed-off-by: N Balachandran <nbalacha@redhat.com>

* glusterd: fix brick restart parallelismAtin Mukherjee2017-11-016-32/+87
| | | | | | | | | | | | | | | | | | | | | | | | | | glusterd's brick restart logic is not always sequential as there is atleast three different ways how the bricks are restarted. 1. through friend-sm and glusterd_spawn_daemons () 2. through friend-sm and handling volume quorum action 3. through friend handshaking when there is a mimatch on quorum on friend import. In a brick multiplexing setup, glusterd ended up trying to spawn the same brick process couple of times as almost in fraction of milliseconds two threads hit glusterd_brick_start () because of which glusterd didn't have any choice of rejecting any one of them as for both the case brick start criteria met. As a solution, it'd be better to control this madness by two different flags, one is a boolean called start_triggered which indicates a brick start has been triggered and it continues to be true till a brick dies or killed, the second is a mutex lock to ensure for a particular brick we don't end up getting into glusterd_brick_start () more than once at same point of time.

* glusterd: clean up portmap on brick disconnectAtin Mukherjee2017-10-314-11/+46
| | | | | | | | | | | | | | | | | | | | GlusterD's portmap entry for a brick is cleaned up when a PMAP_SIGNOUT event is initiated by the brick process at the shutdown. But if the brick process crashes or gets killed through SIGKILL then this event is not initiated and glusterd ends up with a stale port. Since GlusterD's portmap traversal happens both ways, forward for allocation and backward for registry search, there is a possibility that glusterd might end up running with a stale port for a brick which eventually will end up with clients to fail to connect to the bricks. Solution is to clean up the port entry in case the process is down as part of the brick disconnect event. Although with this the handling PMAP_SIGNOUT event becomes redundant in most of the cases, but this is the safeguard method to avoid glusterd getting into the stale port issues.

* glusterd: persist brickinfo's port change into glusterd's storeGaurav Yadav2017-10-315-10/+62
| | | | | | | | | | | | | | | | | | Problem: Consider a case where node reboot is performed and prior to reboot brick was listening to 49153. Post reboot glusterd assigned 49152 to brick and started the brick process but the new port was never persisted. Now when glusterd restarts glusterd always read the port from its persisted store i.e 49153 however pmap signin happens with the correct port i.e 49152. Fix: Make sure when glusterd_brick_start is called, glusterd_store_volinfo is eventually invoked.
