* libglusterfs: Move devel headers under glusterfs directoryShyamsundarR2018-12-051-176/+0
| | | | | | | | | | | | | | | | | | | | | | | | libglusterfs devel package headers are referenced in code using include semantics for a program, this while it works can be better especially when dealing with out of tree xlator builds or in general out of tree devel package usage. Towards this, the following changes are done, - moved all devel headers under a glusterfs directory - Included these headers using system header notation <> in all code outside of libglusterfs - Included these headers using own program notation "" within libglusterfs This change although big, is just moving around the headers and making it correct when including these headers from other sources. This helps us correctly include libglusterfs includes without namespace conflicts.

* glusterd: Update op-version from 4.2 to 5.0ShyamsundarR2018-09-131-6/+8
| | | | | | | | | | | | Post changing the max op-version to 4.2, after release 4.1 branching, the decision was to go with increasing release numbers. Thus this needs to change to 5.0. This commit addresses the above change. Fixes: bz#1628664 Change-Id: Ifcc0c6da90fdd51e4eceea40749511110a432cce Signed-off-by: ShyamsundarR <srangana@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Right now there are two types of upcalls * poll method * registering callback But callback can be registered per fs and same callback fn shall be used for any lease recall with object handle as argument as done for cache invalidation. TODO: RECALL LEASE for each glfd (for future reference) (may be needed fo Samba as they do not deal with object handles. In case of RECALL_LEASE, we could associate separate cbk function for each glfd either by - extending pub_glfs_lease to accept new args (recall_cbk_fn, cookie) - or by defining new API "glfs_register_recall_cbk_fn (glfd, recall_cbk_fn, cookie) . In such cases, flag it and instead of calling below upcall functions, define a new one to go through the glfd list and invoke each of theirs recall_cbk_fn. Plus added following as well * passed lease id to dict in required arguments * added flag check in pub_glfs_open Updates: #350 Change-Id: I07a971f0f26ec6aae0b9f9a5613504317dee153b Signed-off-by: Soumya Koduri <skoduri@redhat.com> Signed-off-by: Poornima G <pgurusid@redhat.com> Signed-off-by: Jiffin Tony Thottan <jthottan@redhat.com>
* cluster/dht: avoid overwriting client writes during migrationSusant Palai2018-02-021-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | For more details on this issue see https://github.com/gluster/glusterfs/issues/308 Solution: This is a restrictive solution where a file will not be migrated if a client writes to it during the migration. This does not check if the writes from the rebalance and the client actually do overlap. If dht_writev_cbk finds that the file is being migrated (PHASE1) it will set an xattr on the destination file indicating the file was updated by a non-rebalance client. Rebalance checks if any other client has written to the dst file and aborts the file migration if it finds the xattr. updates gluster/glusterfs#308 Change-Id: I73aec28bc9dbb8da57c7425ec88c6b6af0fbc9dd Signed-off-by: Susant Palai <spalai@redhat.com> Signed-off-by: Raghavendra G <rgowdapp@redhat.com> Signed-off-by: N Balachandran <nbalacha@redhat.com>

* cluster/afr: Adding option to take full file lockkarthik-us2018-01-191-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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".

* glusterd : fix client io-threads option for replicate volumesRavishankar N2017-10-091-0/+2
| | | | | | | | | | | | | | | | | | | Problem: Commit ff075a3d6f9b142911d25c27fd209838782bfff0 disabled loading client-io-threads for replicate volumes (it was set to on by default in commit e068c1997314046658dd502e9118dab32decf879) due to performance issues but in doing so, inadvertently failed to load the xlator even if the user explicitly enabled the option using the volume set command. This was despite returning returning sucess for the volume set. Fix: Modify the check in perfxl_option_handler() and add checks in volume create/add-brick/remove-brick code paths, tying it all to GD_OP_VERSION_3_12_2.

* protocol/server: make listen backlog value as configurableMohammed Rafi KC2017-06-081-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | problem: When we call listen from protocol/server, we are giving a hard coded valie of 10 if it is not manually given. With multiplexing, especially when glusterd restarts all clients may try to connect to the server at a time. Which will result in overflowing the queue, and kernel will complain about the errors. Solution: This patch will introduce a volume set command to make backlog value as a configurable. This patch also changes the default values for backlog from 10 to 128. This changes is only applicable for sockets listening from protocol. Example: gluster volume set <volname> transport.listen-backlog 1024 Note: 1 Brick has to be restarted to get this value in effect 2 This changes won't be reflected in glusterd, or other xlators which calls listen. If you need, you have to add this option to the volfile.

* core: make the per glusterfs_ctx_t timer-wheel refcountedNiels de Vos2017-05-011-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | xlators can use a 'global' timer-wheel for scheduling events. This timer-wheel is managed per glusterfs_ctx_t, but does not need to be allocated for every graph. When an xlator wants to use the timer-wheel, it will be instanciated on demand, and provided to xlators that request it later on. By adding a reference counter to the glusterfs_ctx_t for the timer-wheel, the threads and structures can be cleaned up when the last xlator does not have a need for it anymore. In general, the xlators request the timer-wheel in init(), and they should return it in fini(). Because the timer-wheel is managed per glusterfs_ctx_t, the functions can be added to ctx.c and do not need to live in their very minimal tw.[ch] files.

* libglusterfs: provide standardized atomic operationsNiels de Vos2017-04-051-17/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The current macros ATOMIC_INCREMENT() and ATOMIC_DECREMENT() expect a lock as first argument. There are at least two issues with this approach: 1. this lock is unused on architectures that have atomic operations 2. some structures use a single lock for multiple variables By defining a gf_atomic_t type, the unused lock can be removed, saving a few bytes on modern architectures. Because the gf_atomic_t type locates the lock for the variable (in case of older architectures), each variable is protected the same on all architectures. This makes the behaviour across all architectures more equal (per variable locking, by a gf_lock_t or compiler optimization).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Fix to https://bugzilla.redhat.com/show_bug.cgi?id=1316873 has made changes to set dirty flag before every update fop, data or metadata, and unset it after successful operation. That makes some of the fops very slow such as entry operations or metadata operations. Solution: File data operations are the only operation which take some time and setting dirty flag before a fop and unsetting it after serves the purpose as probability of failure of a fop is high when the time duration is more. For all the other operations, set dirty flag at the end of the fop, if any brick is down and need heal. Providing following option to choose between high performance or better heal marking for metadata and entry fops. Set/Unset dirty flag for every update fop at the start of the fop. If ON, this option impacts performance of entry operations or metadata operations as it will set dirty flag at the start and unset it at the end of ALL update fop. If OFF and all the bricks are good, dirty flag will be set at the start only for file fops For metadata and entry fops dirty flag will not be set at the start, if all the bricks are good. This does not impact performance for metadata operations and entry operation but has a very small window to miss marking entry as dirty in case it is required to be healed.

* glusterd: Get maximum supported op-version in a clusterSamikshan Bairagya2017-01-081-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | gluster volume get <VOLNAME> cluster.opversion gives us the current op-version on which the cluster is operating. There is no command that lets the user know the maximum supported op-version that the cluster can run on. This patch adds a new global option cluster.max-op-version, that can be used to retrieve the maximum supported op-version in a cluster. Usage: # gluster volume get all cluster.max-op-version Example output: Option Value ------ ----- cluster.max-op-version 30900 NOTE: The only way to test this feature for now is to set the GD_OP_VERSION_MAX macro to different values (30800 for 3.8,30900 for 3.9, and so on) and rebuild glusterd. Since the regression test framework currently doesn't have support to simulate these tests, there are no accompanying regression tests for this feature. It should be possible to add tests once glusto comes in and makes it easier to run a heterogeneous cluster.

Also, since the aforementioned commit was reverted from 3.7 and 3.8 branches, introduce GD_OP_VERSION_3_9_0 and change the op-version for this feature to GD_OP_VERSION_3_9_0.

* cluster/ec: Provide an option to enable/disable eager lockAshish Pandey2016-03-151-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: If a fop takes lock, and completes its operation, it waits for 1 second before releasing the lock. However, If ec find any lock contention within this time period, it release the lock immediately before time expires. As we take lock on first brick, for few operations, like read, it might happen that discovery of lock contention might take long time and can degrades the performance. Solution: Provide an option to enable/disable eager lock. If eager lock is disabled, lock will be released as soon as fop completes. gluster v set <VOLUME NAME> disperse.eager-lock on gluster v set <VOLUME NAME> disperse.eager-lock off Change-Id: I000985a787eba3c190fdcd5981dfbf04e64af166 BUG: 1314649 Signed-off-by: Ashish Pandey <aspandey@redhat.com> Reviewed-on: http://review.gluster.org/13605 Smoke: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> Tested-by: Pranith Kumar Karampuri <pkarampu@redhat.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org>

* rpc: add owner xlator argument to rpc_clnt_newKrishnan Parthasarathi2015-08-121-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The @owner argument tells RPC layer the xlator that owns the connection and to which xlator THIS needs be set during network notifications like CONNECT and DISCONNECT. Code paths that originate from the head of a (volume) graph and use STACK_WIND ensure that the RPC local endpoint has the right xlator saved in the frame of the call (callback pair). This guarantees that the callback is executed in the right xlator context. The client handshake process which includes fetching of brick ports from glusterd, setting lk-version on the brick for the session, don't have the correct xlator set in their frames. The problem lies with RPC notifications. It doesn't have the provision to set THIS with the xlator that is registered with the corresponding RPC programs. e.g, RPC_CLNT_CONNECT event received by protocol/client doesn't have THIS set to its xlator. This implies, call(-callbacks) originating from this thread don't have the right xlator set too. The fix would be to save the xlator registered with the RPC connection during rpc_clnt_new. e.g, protocol/client's xlator would be saved with the RPC connection that it 'owns'. RPC notifications such as CONNECT, DISCONNECT, etc inherit THIS from the RPC connection's xlator.

| | | | | | | | | | | | | | | | | | | | | | | | | Till now, the op-version was an incrementing integer that was incremented by 1 for every Y release (when using the X.Y.Z release numbering). This is not flexible enough to handle backports of features into Z releases. Going forward, from the upcoming 3.6.0 release, the op-versions will be multi-digit integer values composed of the version numbers, instead of a simple incrementing integer. An X.Y.Z release will have XYZ as its op-version. Y and Z will always be 2 digits wide and will be padded with 0 if required. This way of bumping op-versions allows for gaps in between the subsequent Y releases. These gaps will allow backporting features from new Y releases into old Z releases.
