* libglusterfs: Move devel headers under glusterfs directoryShyamsundarR2018-12-051-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* rpc: Eliminate conn->lock contention by using more granular locksMohit Agrawal2017-11-281-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | rpc_clnt_submit() acquires conn->lock before call to rpc_transport_submit_request() and subsequent queuing of frame into saved_frames list. However, as part of handling RPC_TRANSPORT_MSG_RECEIVED and RPC_TRANSPORT_MSG_SENT notifications in rpc_clnt_notify(), conn->lock is again used to atomically update conn->last_received and conn->last_sent event timestamps. So when conn->lock is acquired as part of submitting a request, a parallel POLLIN notification gets blocked at rpc layer until the request submission completes and the lock is released. To get around this, this patch call clock_gettime (instead to call gettimeofday) to update event timestamps in conn->last_received and conn->last_sent and to call clock_gettime don't need to call mutex_lock because it (clock_gettime) is thread safe call. Note: Run fio on vm after apply the patch, iops is improved after apply the patch.

* Halo Replication feature for AFR translatorKevin Vigor2017-05-021-11/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Halo Geo-replication is a feature which allows Gluster or NFS clients to write locally to their region (as defined by a latency "halo" or threshold if you like), and have their writes asynchronously propagate from their origin to the rest of the cluster. Clients can also write synchronously to the cluster simply by specifying a halo-latency which is very large (e.g. 10seconds) which will include all bricks. In other words, it allows clients to decide at mount time if they desire synchronous or asynchronous IO into a cluster and the cluster can support both of these modes to any number of clients simultaneously. There are a few new volume options due to this feature: halo-shd-latency: The threshold below which self-heal daemons will consider children (bricks) connected. halo-nfsd-latency: The threshold below which NFS daemons will consider children (bricks) connected. halo-latency: The threshold below which all other clients will consider children (bricks) connected. halo-min-replicas: The minimum number of replicas which are to be enforced regardless of latency specified in the above 3 options. If the number of children falls below this threshold the next best (chosen by latency) shall be swapped in. New FUSE mount options: halo-latency & halo-min-replicas: As descripted above. This feature combined with multi-threaded SHD support (D1271745) results in some pretty cool geo-replication possibilities. Operational Notes: - Global consistency is gaurenteed for synchronous clients, this is provided by the existing entry-locking mechanism. - Asynchronous clients on the other hand and merely consistent to their region. Writes & deletes will be protected via entry-locks as usual preventing concurrent writes into files which are undergoing replication. Read operations on the other hand should never block. - Writes are allowed from _any_ region and propagated from the origin to all other regions. The take away from this is care should be taken to ensure multiple writers do not write the same files resulting in a gfid split-brain which will require resolution via split-brain policies (majority, mtime & size). Recommended method for preventing this is using the nfs-auth feature to define which region for each share has RW permissions, tiers not in the origin region should have RO perms. TODO: - Synchronous clients (including the SHD) should choose clients from their own region as preferred sources for reads. Most of the plumbing is in place for this via the child_latency array. - Better GFID split brain handling & better dent type split brain handling (i.e. create a trash can and move the offending files into it). - Tagging in addition to latency as a means of defining which children you wish to synchronously write to Test Plan: - The usual suspects, clang, gcc w/ address sanitizer & valgrind - Prove tests Reviewers: jackl, dph, cjh, meyering Reviewed By: meyering Subscribers: ethanr Differential Revision: https://phabricator.fb.com/D1272053 Tasks: 4117827 Change-Id: I694a9ab429722da538da171ec528406e77b5e6d1 BUG: 1428061 Signed-off-by: Kevin Vigor <kvigor@fb.com> Reviewed-on: http://review.gluster.org/16099 Reviewed-on: https://review.gluster.org/16177 Tested-by: Pranith Kumar Karampuri <pkarampu@redhat.com> Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com>

| | | | | | | | | | | | | | | | | While doing glfs_fini(), all the xlators are first notified of PARENT_DOWN. protocol-client xlator on receving that notification does rpc_clnt_disable which disassociates rpc->conn with its transport object and does socket shutdown.

* rpc: fix deadlock when unref is inside conn->lockKrishnan Parthasarathi2015-04-101-70/+91
| | | | | | | | | | | | | | | | | In ping-timer implementation, the timer event takes a ref on the rpc object. This ref needs to be removed after every timeout event. ping-timer mechanism could be holding the last ref. For e.g, when a peer is detached and its rpc object was unref'd. In this case, ping-timer mechanism would try to acquire conn->mutex to perform the 'last' unref while being inside the critical section already. This will result in a deadlock.

| | | | | | | | | | | | | | | | | | | | | | | | | | | This is to avoid indefinite recursion of the following kind, that could lead to a stack overflow: rpc_clnt_start_ping() -> rpc_clnt_ping() -> rpc_clnt_submit() -> rpc_clnt_start_ping() -> rpc_clnt_ping() -> rpc_clnt_submit() ... and so on, since it is possible that before rpc_clnt_start_ping() is called a second time by the thread executing this codepath, the response to previous ping request could ALWAYS come by and cause epoll thread to reset conn->ping_started to 0. This patch also fixes the issue of excessive ping traffic, which was due to the client sending one ping rpc for every fop in the worst case. Also removed dead code in glusterd.

* glusterd: Ping timer implmentationKrishnan Parthasarathi2014-04-291-0/+266
This patch refactors the existing client ping timer implementation, and makes use of the common code for implementing both client ping timer and the glusterd ping timer. A new gluster rpc program for ping is introduced. The ping timer is only started for peers that have this new program. The deafult glusterd ping timeout is 30 seconds. It is configurable by setting the option 'ping-timeout' in glusterd.vol . Also, this patch introduces changes in the glusterd-handshake path. The client programs for a peer are now set in the callback of dump_versions, for both the older handshake and the newer op-version handshake. This is the only place in the handshake process where we know what programs a peer supports.
