* rpc/clnt: Don't let consumers manage "connected" stateRaghavendra G2018-06-0410-99/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The state management of "connected" in rpc is ad-hoc as far as the responsibility goes. Note that there is nothing wrong with functionality itself. rpc layer manages this state in disconnect codepath and has exposed an api to manage this one from consumers. Note that rpc layer never sets "connected" to true by itself, which forces the consumers to use this api to get a working rpc connection. The situation is best captured from a comment in code from Jeff Darcy in glusterfsd/src/gf-attach.c: -/* - * In a sane world, the generic RPC layer would be capable of tracking - * connection status by itself, with no help from us. It might invoke our - * callback if we had registered one, but only to provide information. Sadly, - * we don't live in that world. Instead, the callback *must* exist and *must* - * call rpc_clnt_{set,unset}_connected, because that's the only way those - * fields get set (with RPC both above and below us on the stack). If we don't - * do that, then rpc_clnt_submit doesn't think we're connected even when we - * are. It calls the socket code to reconnect, but the socket code tracks this - * stuff in a sane way so it knows we're connected and returns EINPROGRESS. - * Then we're stuck, connected but unable to use the connection. To make it - * work, we define and register this trivial callback. - */ Also, consumers of rpc know about state of connection only through the notifications sent by rpc-clnt. So, consumers don't have any extra information to manage the state and hence letting them manage the state is counter intuitive. This patch cleans that up and instead moves the responsibility of state management of rpc layer into itself.

* posix/ctime: Fix fops racing in updating mtime/atimeKotresh HR2018-06-031-11/+31
| | | | | | | | | | | | | | | | In distributed systems, there could be races with fops updating mtime/atime which could result in different mtime/atime for same file. So updating them only if time is greater than the existing makes sure, only the highest time is retained. If the mtime/atime update comes from the explicit utime syscall, it is allowed to set to previous time. Thanks Xavi for helping in rooting the issue. fixes: bz#1584981 Change-Id: If1230a75b96d7f9a828795189fcc699049e7826e Signed-off-by: Kotresh HR <khiremat@redhat.com>

* glusterd: address test failures with brick mux enabledAtin Mukherjee2018-05-315-2/+22
| | | | | | | | | | | | | | | | | | | | | | This patch addresses following: 1. On volume stop, for the last brick, pmap_registry_remove () is invoked by glusterd. 2. If a brick process is sigkilled, remove all the associated brick instances from the portmap. 3. Bump up PROCESS_UP_TIMEOUT to 45. 4. gf_attach to kill a brick takes more time in mux (which is an issue that needs a fix), but in the interim, give br-state-check.t more time to complete (there are 2 kill_bricks, each taking 120 seconds, and the test usually passes in 30 odd seconds, hence bumping this up to 350 seconds) 5. The test bug-1559004-EMLINK-handling.t is taking ~950 seconds at times on master without mux, in mux cases, when it fails, it is almost at the last iteration, hence bumping the timeout for this test case to reduce regression error rates Updates: bz#1577672 Change-Id: I1922675e112baca4c125c4c094eaa42a11e34e67 Signed-off-by: Atin Mukherjee <amukherj@redhat.com>
* protocol/client: Don't send fops till SETVOLUME is completeRaghavendra G2018-05-312-3/+9
| | | | | | | | | | | | | | | | | An earlier commit set conf->connected just after rpc layer sends RPC_CLNT_CONNECT event. However, success of socket level connection connection doesn't indicate brick stack is ready to receive fops, as an handshake has to be done b/w client and server after RPC_CLNT_CONNECT event. Any fop sent to brick in the window between, * protocol/client receiving RPC_CLNT_CONNECT event * protocol/client receiving a successful setvolume response can end up accessing an uninitialized brick stack. So, set conf->connected only after a successful SETVOLUME. Change-Id: I139a03d2da6b0d95a0d68391fcf54b00e749decf fixes: bz#1583937 Signed-off-by: Raghavendra G <rgowdapp@redhat.com>

Prashanth notes that unicode strings in py2 need 'u' prefix; unicode strings in py3 3.0, 3.1, and 3.2 a 'u' prefix will throw an error, but in py3 3.3+ it is legal (or just ignored). All Linux dists we care about have 3.3 or later so we can leave 'u' prefixes on unicode strings. Change-Id: I49bba2f328b0ee24b9a8115a7183be979981563e updates: #411 Signed-off-by: Kaleb S.

* Revert "performance/write-behind: fix flush stuck by former failed writes"Raghavendra G2018-05-291-7/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 9340b3c7a6c8556d6f1d4046de0dbd1946a64963. operations/writes across different fds of the same file cannot be considered as independent. For eg., man 2 fsync states, <man 2 fsync> fsync() transfers ("flushes") all modified in-core data of (i.e., modified buffer cache pages for) the file referred to by the file descriptor fd to the disk device </man> This means fsync is an operation on file and fd is just a way to reach file. So, it has to sync writes done on other fds too. Patch 9340b3c7a6c, prevents this. The problem fixed by patch 9340b3c7a6c - a flush on an fd is hung on a failed write (held in cache for retrying) on a different fd - is solved in this patch by making sure __wb_request_waiting_on considers failed writes on any fd as dependent on flush/fsync on any fd (not just the fd on which writes happened) opened on the same file. This means failed writes on any fd are either synced or thrown away on witnessing flush/fsync on any fd of the same file.

* glusterd: glusterd is releasing the locks before timeoutSanju Rakonde2018-05-287-0/+80
| | | | | | | | | | | | | | | | | | | Problem: We introduced lock timer in mgmt v3, which will realease the lock after 3 minutes from command execution. Some commands related to heal/profile will take more time to execute. For these comands timeout is set to 10 minutes. As the lock timer is set to 3 minutes glusterd is releasing the lock after 3 minutes. That means locks are released before the command is completed its execution. Solution: Pass a timeout parameter from cli to glusterd, when there is a change in default timeout value(i.e, default timeout value can be changed through command line or for the commands related to profile/heal we will change the default timeout value to 10 minutes.) glusterd will set the lock timer timeout according to the timeout value passed.

Following is the race we are trying to solve with this patch. 1) We have a file with content 'abc' 2) lookup and writev which replaces 'abc' with 'def' comes. Lookup fetches abc but yet to update the cache, and then immediately writev is wound which zeros out the cache. Now lookup_cbk updates the buffer with 'abc' even though on disk it is 'def'. Now writev completes and returns to application. 3) application does a readv which will be fetched from quick-read as 'abc'.

* cluster/dht: Increase failure count for lookup failure in remove-brick opSusant Palai2018-05-281-3/+31
| | | | | | | | | | | | | | | | | | An entry from readdirp might get renamed just before migration leading to lookup failures. For such lookup failure, remove-brick process does not see any increment in failure count. Though there is a warning message after remove-brick commit for the user to check in the decommissioned brick for any files those are not migrated, it's better to increase the failure count so that user can check in the decommissioned bricks for files before commit. Note: This can result in false negative cases for rm -rf interaction with remove-brick op, where remove-brick shows non-zero failed count, but the entry was actually deleted by user.

* features/sdfs: implement readdirpRaghavendra G2018-05-241-3/+144
| | | | | | | | | | Since readdirp acts as a batched lookup for all dentries it reads, it has to synchronize with any entry operation within the directory being read. Change-Id: I923a6ebd21856dbaa5fa5db4a26a29b7b29b3159 Signed-off-by: Raghavendra G <rgowdapp@redhat.com> fixes: #421
* rpc: Don't reset auth_value in disconnectKotresh HR2018-05-241-12/+48
| | | | | | | | | | | | | The auth_value was being reset to AUTH_GLUSTERFS_v2 during rpc disconnect. It shoud not be reset. The disconnect during portmap request can race with handshake. If handshake happens first and disconnect later, auth_value would set to default value and it never sets back to actual auth_value fixes: bz#1579276 Change-Id: Ib46c9e01a97f6defb3fd1e0423fdb4b899b4a361 Signed-off-by: Kotresh HR <khiremat@redhat.com>
* cluster/ec: Fix pre-op xattrop managementXavi Hernandez2018-05-233-32/+66
| | | | | | | | | | | | | | | | | | | | Multiple pre-op xattrop can be simultaneously being processed. On the cbk it was checked if the fop was waiting for some specific data (like size and version) and, if so, it was assumed that this answer should contain that data. This is not true, since a fop can be waiting for some data, but it may come from the xattrop of another fop. This patch differentiates between needing some information and providing it. This is related to parallel writes. Disabling them fixed the problem, but also prevented concurrent reads. A change has been made so that disabling parallel writes still allows parallel reads.

* features/cloudsync: Make plugins configurableSusant Palai2018-05-223-6/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch brings the configuration option for plugins. For new plugins, an entry has to be created in to cs_plugin structure e.g. struct cs_plugin plugins[] = { { .name = "amazons3", .library = "libamazons3.so", .description = "amazon s3 store." }, {.name = NULL}, }; Library field describes the name of the shared library for the plugin. To configure plugin type "feature.cloudsync-storetype" option need to be set to the remote-store type. e.g. gluster volume set VOLNAME cloudsync-storetype amazons3. This should be same as the ".name" field in cs_plugin structure. cs_init will pick this up in run time to load the plugin.

* afr: fix bug-1363721.t failureRavishankar N2018-05-214-2/+63
| | | | | | | | | | | | | | | | | | | | | | 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. Note: This fix is not related to brick muliplexing. I ran the .t 10 times with this fix and brick-mux enabled without any failures.

* Fix for memory-leak in crypt xlatorGergo Huszty2018-05-212-235/+248
| | | | | | | | | | | | Crypt xlator occasionaly uses local storage in it's call frame. These frames are managed with common macroes, which does not take care about cleaning up such local storages. The fix is similar to the other xlators' solution. A crypt specific macro handles the cleaning of the local storage when it is allocated.
