* cluster/afr: remove unnecessary child_up initializationXavier Hernandez2018-02-061-7/+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.

* cluster/dht: Add migration checks to dht_(f)xattropN Balachandran2018-02-069-45/+363
| | | | | | | | | | | | | | | | The dht_(f)xattrop implementation did not implement migration phase1/phase2 checks which could cause issues with rebalance on sharded volumes.

* tests: Fix a broken test casePoornima G2018-02-051-1/+3
| | | | | | | | | | | | | | | | | | | | | | Issue: When using statedump command to take statedump of the gfapi process, we specify the following things: $gluster volume statedump <volname> client <host>:<pid> pid: Pid of the gfapi application host: This should be the IP/hostname as seen by the glusterd, the gfapi application is connected to. In this test case, if gfapi application is running locally, and is connected to $H1 glusterd, the <host> need not be $H1. <host> could be localhost, 127.0.0.1, 127.1.1.1 etc. based on the configuration of the system.

* glusterd: process pmap sign in only when port is marked as freeAtin Mukherjee2018-02-021-0/+15
| | | | | | | | | | | | | | | | | | | Because of some crazy race in volume start code path because of friend handshaking with volumes with quorum enabled we might end up into a situation where glusterd would start a brick and get a disconnect and then immediately try to start the same brick instance based on another friend update request. And then if for the very first brick even if the process doesn't come up at the end sign in event gets sent and we end up having two duplicate portmap entries for the same brick. Since in brick start we mark the previous port as free, its better to consider a sign in request as no op if the corresponding port type is marked as free. >mainline patch : https://review.gluster.org/#/c/19263/ Change-Id: I995c348c7b6988956d24b06bf3f09ab64280fc32 BUG: 1537346 Signed-off-by: Atin Mukherjee <amukherj@redhat.com> (cherry picked from commit 9d708a3739c8201d23f996c413d6b08f8b13dd90)

* geo-rep: Fix data sync issue during hardlink, renameKotresh HR2018-02-021-2/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: The data is not getting synced if master witnessed IO as below. 1. echo "test_data" > f1 2. ln f1 f2 3. mv f2 f3 4. unlink f1 On master, 'f3' exists with data "test_data" but on slave, only f3 exists with zero byte file without backend gfid link. Cause: On master, since 'f2' no longer exists, the hardlink is skipped during processing. Later, on trying to sync rename, since source ('f2') doesn't exist, dst ('f3') is created with same gfid. But in this use case, it succeeds but backend gfid would not have linked as 'f1' exists with the same gfid. So, rsync would fail with ENOENT as backend gfid is not linked with 'f3' and 'f1' is unlinked. Fix: On processing rename, if src doesn't exist on slave, don't blindly create dst with same gfid. The gfid needs to be checked, if it exists, hardlink needs to be created instead of mknod.

* cluster/dht: Use percentages for space checkN Balachandran2018-01-122-5/+25
| | | | | | | | | | | | | | | | | | | | | With heterogenous bricks now being supported in DHT we could run into issues where files are not migrated even though there is sufficient space in newly added bricks which just happen to be considerably smaller than older bricks. Using percentages instead of absolute available space for space checks can mitigate that to some extent. Marking bug-1247563.t as that used to depend on the easier code to prevent a file from migrating. This will be removed once we find a way to force a file migration failure. > Change-Id: I3452520511f304dbf5af86f0632f654a92fcb647 > BUG: 1529440 > Signed-off-by: N Balachandran <nbalacha@redhat.com> Change-Id: I3452520511f304dbf5af86f0632f654a92fcb647 BUG: 1530455 Signed-off-by: N Balachandran <nbalacha@redhat.com>
* quota: fixes issue in quota.conf when setting large number of limitsSanoj Unnikrishnan2018-01-101-12/+33
| | | | | | | | | | | | | | | | Problem: It was not possible to configure more than 7712 quota limits. This was because a stack buffer of size 131072 was used to read from quota.conf file. In the new format of quota.conf file each gfid entry takes 17bytes (16byte gfid + 1 byte type). So, the buf_size was not a multiple of gfid entry size and as per code this was considered as corruption.

* Revert "mount/fuse: report ESTALE as ENOENT"Raghavendra G2018-01-101-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 26d16b90ec7f8acbe07e56e8fe1baf9c9fa1519e. Consider rename (index.new, store.idx) and open (store.idx) being executed in parallel. When we break down operations following sequence is possible. * lookup (store.idx) - as part of open(store.idx) returns gfid1 as the result. * rename (index.new, store.idx) changes gfid of store.idx to gfid2. Note that gfid2 was the nodeid of index.new. Since rename is successful, gfid2 is associated with store.idx. * open (store.idx) resumes and issues open fop to glusterfs with gfid1. open in glusterfs fails as gfid1 doesn't exist and the error returned by glusterfs to kernel-fuse is ENOENT. * kernel passes back the same error to application as a result to open. This error could've been prevented if kernel retries open with gfid2. Interestingly kernel do retry open when it receives ESTALE error. Even though failure to find gfid resulted in ESTALE error, commit 26d16b90ec7f8acb converted that error to ENOENT while sending an error reply to kernel. This prevented kernel from retrying open resulting in error. >Change-Id: I2e752ca60dd8af1b989dd1d29c7b002ee58440b4 >BUG: 1500269 >Signed-off-by: Raghavendra G <rgowdapp@redhat.com> (cherry picked from commit 019a55e708375d2b1e576fcc948a691bcdc5c749) Change-Id: I2e752ca60dd8af1b989dd1d29c7b002ee58440b4 BUG: 1529088 Signed-off-by: Raghavendra G <rgowdapp@redhat.com>

* performance/write-behind: fix bug while handling short writesRaghavendra G2018-01-021-2/+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: 1529095 Signed-off-by: Raghavendra G <rgowdapp@redhat.com>

* mount/fuse: use fstat in getattr implementation if any opened fd is availableRaghavendra G2018-01-022-12/+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: 1529085 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.

But the timeout was not honored and was able to access the file even after the timeout. Fix: Call the inode_invalidate() in afr_set_split_brain_choice_cbk() so that it will triger the cache invalidate after resetting the timer and the split brain choice.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | xattrs may very well contain binary, non-text data with leading 0 values. Using strcmp for checking empty values is not the appropriate thing to do: In the best case, it might treat a binary xattr value starting with 0 from being cached (and hence also from being reported back with xattr). In the worst case, we might read beyond the end of a data blob that does contain any zero byte. We fix this by checking the length of the data blob and checking the first byte against 0 if the length is one. > Signed-off-by: Guenther Deschner <gd@samba.org> > Pair-Programmed-With: Michael Adam <obnox@samba.org> > Change-Id: If723c465a630b8a37b6be58782a2724df7ac6b11 > BUG: 1476324 > Reviewed-on: https://review.gluster.org/17910 > Reviewed-by: Michael Adam <obnox@samba.org> > Smoke: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Poornima G <pgurusid@redhat.com> > Tested-by: Poornima G <pgurusid@redhat.com> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > (cherry picked from commit ab4ffdac9dec1867f2d9b33242179cf2b347319d) Change-Id: If723c465a630b8a37b6be58782a2724df7ac6b11 BUG: 1499892 Signed-off-by: Günther Deschner <gd@samba.org>

* glusterd: clean up portmap on brick disconnectAtin Mukherjee2017-11-064-11/+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. > mainline patch : https://review.gluster.org/#/c/18541/ Change-Id: I04c5be6d11e772ee4de16caf56dbb37d5c944303 BUG: 1507747 Signed-off-by: Atin Mukherjee <amukherj@redhat.com> (cherry picked from commit 30e0b86aae00430823f2523c6efa3c4ebbf0a478)
* glusterd: fix brick restart parallelismAtin Mukherjee2017-11-066-32/+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.

| | | | | | | | | | | | | | | | | | 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.
