* build: rename event.h to gf-event.hNiels de Vos2018-07-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Newer FreeBSD versions (noticed with 10.3-RELEASE) provide a event.h file that on occasion gets included instead of the libglusterfs file. When this happens, 'struct event_pool' will not be defined and building will fail with errors like: autoscale-threads.c:18:55: error: incomplete definition of type 'struct event_pool' int thread_count = pool->eventthreadcount; ~~~~^ autoscale-threads.c:17:16: note: forward declaration of 'struct event_pool' struct event_pool *pool = ctx->event_pool; ^ This problem is caused by 'pkg-config --cflags uuid' that adds /usr/local/include to the GF_CPPFLAGS. The use of libuuid is preferred so that the contrib/uuid/ directory can be removed. By renaming event.h to gf-event.h there is no conflict between the different event.h files anymore and compiling on FreeBSD works without issues.

* server: Set ssl-allow option in options table and rename IDPrashanth Pai2018-07-111-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change explicitly adds 'ssl-allow' options to the server xlator's options table so that glusterd2 can see it as a settable option. This change also marks 'auth.allow' and 'auth.reject' options as a settable. Glusterd2 doesn't maintain a separate volume options table. Glusterd2 dynamically loads shared objects of xlators to read their option table and other information. Glusterd2 reads 'xlator_api_t' if available. If that's not available, it falls back to reading just the options table directly. In glusterd2, volume set operations are performed by users on keys of the format <xlator>.<option-name>. Glusterd2 uses xlator name set in 'xlator_api_t.identifier'. If that's not present it will use the shared object's file name as xlator name. Hence, it is important for 'xlator_api_t.identifier' to be set properly, and in this case, the proper value is "server". This name shall be used by users as prefix while setting volume options implemented in server xlator. The name will also be used in volfile. A user in glusterd2 can authorize a client over TLS as follows: $ glustercli volume set <volname> server.ssl-allow <client1-CN>[,<clientN-CN>] gd2 References: https://github.com/gluster/glusterd2/issues/971 https://github.com/gluster/glusterd2/issues/214 https://github.com/gluster/glusterd2/pull/967 Updates: bz#1193929 Change-Id: I59ef58acb8d51917e6365a83be03e79ae7c5ad17 Signed-off-by: Prashanth Pai <ppai@redhat.com>

* protocol/server: don't assume there would be a volfile idAmar Tumballi2018-05-081-1/+9
| | | | | | | | | | | | | | | | | | | | | Earlier glusterfs never had an assumption someone would start it with right arguments, and brick processes would be spawned by a management layer. It just assume the role based on the volfile. Other than volfile, no other arguments should be technically mandatory for working of glusterfs. With this patch, that assumption holds true. Updates: github issue # 352 A note on why this particular issue for this basic sanity? As per the design of thin-arbiter/tie-breaker, it can be started independently on any machine, without need of glusterd. So, similar to 'glusterd', we should be able to spawn a process with any translator without options/volume id etc. fixes: bz#1569399 Change-Id: I5c0650fe0bfde35ad94ccba60e63f6cdcd1ae5ff Signed-off-by: Amar Tumballi <amarts@redhat.com>
* server/auth: add option for strict authenticationMohammed Rafi KC2018-04-201-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When this option is enabled, we will check for a matching username and password, if not found then the connection will be rejected. This also does a checksum validation of volfile The option is invalid when SSL/TLS is in use, at which point the SSL/TLS certificate user name is used to validate and hence authorize the right user. This expects TLS allow rules to be setup correctly rather than the default *. This option is not settable, as a result this cannot be enabled for volumes using the CLI. This is used with the shared storage volume, to restrict access to the same in non-SSL/TLS environments to the gluster peers only. Tested: ./tests/bugs/protocol/bug-1321578.t ./tests/features/ssl-authz.t - Ran tests on volumes with and without strict auth checking (as brick vol file needed to be edited to test, or rather to enable the option) - Ran tests on volumes to ensure existing mounts are disconnected when we enable strict checking Change-Id: I2ac4f0cfa5b59cc789cc5a265358389b04556b59 fixes: bz#1568844 Signed-off-by: Mohammed Rafi KC <rkavunga@redhat.com> Signed-off-by: ShyamsundarR <srangana@redhat.com>

* gluster: Sometimes Brick process is crashed at the time of stopping brickMohit Agrawal2018-04-191-47/+123
| | | | | | | | | | | | | | | | | | | | | | | | Problem: Sometimes brick process is getting crashed at the time of stop brick while brick mux is enabled. Solution: Brick process was getting crashed because of rpc connection was not cleaning properly while brick mux is enabled.In this patch after sending GF_EVENT_CLEANUP notification to xlator(server) waits for all rpc client connection destroy for specific xlator.Once rpc connections are destroyed in server_rpc_notify for all associated client for that brick then call xlator_mem_cleanup for for brick xlator as well as all child xlators.To avoid races at the time of cleanup introduce two new flags at each xlator cleanup_starting, call_cleanup.

* glusterd: volume inode/fd status broken with brick muxhari gowtham2018-04-191-42/+50
| | | | | | | | | | | | | | | | | | | | | | | Problem: The values for inode/fd was populated from the ctx received from the server xlator. Without brickmux, every brick from a volume belonged to a single brick from the volume. So searching the server and populating it worked. With brickmux, a number of bricks can be confined to a single process. These bricks can be from different volumes too (if we use the max-bricks-per-process option). If they are from different volumes, using the server xlator to populate causes problem. Fix: Use the brick to validate and populate the inode/fd status.

* build: address linkage issuesKaleb S. KEITHLEY2018-03-051-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | We have the following undefined symbol error from protocol/server.so: glusterfs_mgmt_pmap_signout glusterfs_autoscale_threads See https://review.gluster.org/19225 (bz#1532238) and https://review.gluster.org/19657 (bz#1550895) (why are there two different bzs for the same bug?) IMO this is a cleaner solution. I.e. moving the above two functions to libgfrpc (.../rpc/rpc-lib/...) I would also, for (foolish) consistency sake, like to see glusterfs_mgmt_pmap_signin() moved from glusterfsd to libgfrpc as well. This works on f28/rawhide, with its new, more restrictive run-time link semantics. The smoke and regression tests on earlier fedora and centos will confirm that it works on those platforms too.

* mgtm/core : use sha hash function for volfile checkMohammed Rafi KC2017-07-101-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We are storing the entire volfile and using this to check volfile change. With brick multiplexing there will be lot of graphs per process which will increase the memory foot print of the process. So instead of storing the entire graph we could use sha256 and we can compare the hash to see whether volfile change happened or not. Also with Brick multiplexing, the direct comparison of vol file is not correct. There are two problems. Problem 1: We are currently storing one single graph (the last updated volfile) whereas, what we need is the entire graph with all atttached bricks. If we fix this issue, we have second problem Problem 2: With multiplexing we have a graph that contains multiple bricks. But what we are checking as part of the reconfigure is, comparing the entire graph with one single graph, which will always fail. Solution: We create list in glusterfs_ctx_t that stores sha256 hash of individual brick graphs. When a graph changes happens we compare the stored hash and the current hash. If the hash matches, then no need for reconfigure. Otherwise we first do the reconfigure and then update the hash. For now, gfapi has not changed this way. Meaning when gfapi volfile fetch or reconfigure happens, we still store the entire graph and compare, each memory. This is fine, because libgfapi will not load brick graphs. But changing the libgfapi will make the code similar in both glusterfsd-mgmt and api. Also it helps to reduce some memory.

* protocol/server: make listen backlog value as configurableMohammed Rafi KC2017-06-081-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | stopped any volume Problem: After enabled brick mux if any volume has down and then try ot run mount with running volume , mount command is hung. Solution: After enable brick mux server has shared one data structure server_conf for all associated subvolumes.After down any subvolume in some ungraceful manner (remove brick directory) posix xlator sends GF_EVENT_CHILD_DOWN event to parent xlatros and server notify updates the child_up to false in server_conf.When client is trying to communicate with server through mount it checks conf->child_up and it is FALSE so it throws message "translator are not yet ready". From this patch updated structure server_conf to save child_up status for xlator wise. Another improtant correction from this patch is cleanup threads from server side xlators after stop the volume.

* rpcsvc: Add rpchdr and proghdr to iobref before submitting to transportPoornima G2017-02-151-7/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue: When fio is run on multiple clients (each client writes to its own files), and meanwhile the clients does a readdirp, thus the client which did a readdirp will now recieve the upcalls. In this scenario the client disconnects with rpc decode failed error. RCA: Upcall calls rpcsvc_request_submit to submit the request to socket: rpcsvc_request_submit currently: rpcsvc_request_submit () { iobuf = iobuf_new iov = iobuf->ptr fill iobuf to contain xdrised upcall content - proghdr rpcsvc_callback_submit (..iov..) ... if (iobuf) iobuf_unref (iobuf) } rpcsvc_callback_submit (... iov...) { ... iobuf = iobuf_new iov1 = iobuf->ptr fill iobuf to contain xdrised rpc header - rpchdr msg.rpchdr = iov1 msg.proghdr = iov ... rpc_transport_submit_request (msg) ... if (iobuf) iobuf_unref (iobuf) } rpcsvc_callback_submit assumes that once rpc_transport_submit_request() returns the msg is written on to socket and thus the buffers(rpchdr, proghdr) can be freed, which is not the case. In especially high workload, rpc_transport_submit_request() may not be able to write to socket immediately and hence adds it to its own queue and returns as successful. Thus, we have use after free, for rpchdr and proghdr. Hence the clients gets garbage rpchdr and proghdr and thus fails to decode the rpc, resulting in disconnect. To prevent this, we need to add the rpchdr and proghdr to a iobref and send it in msg: iobref_add (iobref, iobufs) msg.iobref = iobref; The socket layer takes a ref on msg.iobref, if it cannot write to socket and is adding to the queue. Thus we do not have use after free.

* core: run many bricks within one glusterfsd processJeff Darcy2017-01-301-44/+127
| | | | | | | | | | | | | | | | | | | | | | | This patch adds support for multiple brick translator stacks running in a single brick server process. This reduces our per-brick memory usage by approximately 3x, and our appetite for TCP ports even more. It also creates potential to avoid process/thread thrashing, and to improve QoS by scheduling more carefully across the bricks, but realizing that potential will require further work. Multiplexing is controlled by the "cluster.brick-multiplex" global option. By default it's off, and bricks are started in separate processes as before. If multiplexing is enabled, then *compatible* bricks (mostly those with the same transport options) will be started in the same process.
