* glusterd: socketfile & pidfile related fixes for brick multiplexing featureMohit Agrawal2017-05-101-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: While brick-muliplexing is on after restarting glusterd, CLI is not showing pid of all brick processes in all volumes. Solution: While brick-mux is on all local brick process communicated through one UNIX socket but as per current code (glusterd_brick_start) it is trying to communicate with separate UNIX socket for each volume which is populated based on brick-name and vol-name.Because of multiplexing design only one UNIX socket is opened so it is throwing poller error and not able to fetch correct status of brick process through cli process. To resolve the problem write a new function glusterd_set_socket_filepath_for_mux that will call by glusterd_brick_start to validate about the existence of socketpath. To avoid the continuous EPOLLERR erros in logs update socket_connect code. Test: To reproduce the issue followed below steps 1) Create two distributed volumes(dist1 and dist2) 2) Set cluster.brick-multiplex is on 3) kill glusterd 4) run command gluster v status After apply the patch it shows correct pid for all volumes > BUG: 1444596 > Change-Id: I5d10af69dea0d0ca19511f43870f34295a54a4d2 > Signed-off-by: Mohit Agrawal <moagrawa@redhat.com> > Reviewed-on: https://review.gluster.org/17101 > Smoke: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Prashanth Pai <ppai@redhat.com> > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Atin Mukherjee <amukherj@redhat.com> > (cherry picked from commit 21c7f7baccfaf644805e63682e5a7d2a9864a1e6) Change-Id: Ia95b9d36e50566b293a8d6350f8316dafc27033b BUG: 1449004 Signed-off-by: Mohit Agrawal <moagrawa@redhat.com> Reviewed-on: https://review.gluster.org/17212 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Reviewed-by: Atin Mukherjee <amukherj@redhat.com> Reviewed-by: Prashanth Pai <ppai@redhat.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.org>
* glusterd: Fix removing pmap entry on rpc disconnectPrashanth Pai2017-04-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Problem: The following line of code intended to remove pmap entry for the connection during disconnects: pmap_registry_remove (this, 0, NULL, GF_PMAP_PORT_NONE, xprt); However, no pmap entry will have it's type set to GF_PMAP_PORT_NONE at any point in time. So a call to pmap_registry_search_by_xprt() in pmap_registry_remove() will always fail to find a match. Fix: Optionally ignore pmap entry's type in pmap_registry_search_by_xprt().

| | | | | | | | | | | | | | | | | | | On FreeBSD the S_ISVTX flag is completely ignored when creating a regular file. Since gluster needs to create files with this flag set, specialy for DHT link files, it's necessary to force the flag. This fix does this by calling fchmod() after creating a file that must have this flag set.

* rpcsvc: Add rpchdr and proghdr to iobref before submitting to transportPoornima G2017-02-151-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* glusterd: add a cli command to trigger a statedump on a clientPoornima G2017-01-231-0/+67
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this, we will be able to trigger statedumps on remote Gluster clients, mainly targetted for applications using libgfapi. Design: SIGUSR signal is the most comman way of taking a statedump in Gluster. But it cannot be used for libgfapi based processes, as the process loading the library might have already consumed SIGUSR signal. Hence going by the command way. One has to issue a Gluster command to initiate a statedump on the libgfapi based client. The command takes hostname and PID as an argument. All the glusterds in the cluster, check if they are connected to the specified hostname, and send an RPC request to all the connected clients from that hostname (via the mgmt connection).

* geo-rep: Separate slave mount logs for each connectionKotresh HR2017-01-181-3/+3
| | | | | | | | | | | | | | | | | | | | | Geo-rep worker mounts the slave volume on the slave node. If multiple worker connects to same slave node, all workers share the same mount log file. This is very difficult to debug as logs are cluttered from different mounts. Hence creating separate mount log file for each connection from worker. Each connection from worker is identified uniquely using 'mastervol uuid', 'master host', 'master brickpath', 'salve vol'. The log file name will be combination of the above.

* glusterd: Get maximum supported op-version in a clusterSamikshan Bairagya2017-01-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* glusterd : Introduce reset brickAnuradha Talur2016-08-291-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The command basically allows replace brick with src and dst bricks as same. Usage: gluster v reset-brick <volname> <hostname:brick-path> start This command kills the brick to be reset. Once this command is run, admin can do other manual operations that they need to do, like configuring some options for the brick. Once this is done, resetting the brick can be continued with the following options. gluster v reset-brick <vname> <hostname:brick> <hostname:brick> commit {force} Does the job of resetting the brick. 'force' option should be used when the brick already contains volinfo id. Problem: On doing a disk-replacement of a brick in a replicate volume the following 2 scenarios may occur : a) there is a chance that reads are served from this replaced-disk brick, which leads to empty reads. b) potential data loss if next writes succeed only on replaced brick, and heal is done to other bricks from this one. Solution: After disk-replacement, make sure that reset-brick command is run for that brick so that pending markers are set for the brick and it is not chosen as source for reads and heal. But, as of now replace-brick for the same brick-path is not allowed. In order to fix the above mentioned problem, same brick-path replace-brick is needed. With this patch reset-brick commit {force} will be allowed even when source and destination <hostname:brickpath> are identical as long as 1) destination brick is not alive 2) source and destination brick have the same brick uuid and path. Also, the destination brick after replace-brick will use the same port as the source brick.

* glusterd: Fix gsyncd upgrade issueKotresh HR2016-07-131-2/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: gluster upgrade is not generating new volfiles Cause: During upgrade, "glusterd --xlator-option *.upgrade=on -N" is run to generate new volfiles. It is run post 'glusterfs' rpm installation. The above command fails during upgrade if geo-replication is installed. This is because on glusterd start 'gsyncd' binary is called to configure geo-replication related stuff. Since 'glusterfs' rpm is installed prior to 'geo-rep' rpm, the 'gsyncd' binary used to glusterd upgrade command is of old version and hence it fails before generating new volfiles. Solution: Don't call geo-replication configure during upgrade/downgrade. Geo-replication configuration happens during start of glusterd after upgrade.

* glusterd/geo-rep: slave volume uuid to identify a geo-rep sessionSaravanakumar Arumugam2016-05-121-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Currently, it is possible to create multiple geo-rep session from the Master host to Slave host(s), where Slave host(s) belonging to the same volume. For example: Consider Master Host M1 having volume tv1 and Slave volume tv2, which spans across two Slave hosts S1 and S2. Currently, it is possible to create geo-rep session from M1(tv1) to S1(tv2) as well as from M1(tv1) to S2(tv2). When the Slave Host is alone modified, it is identified as a new geo-rep session (as slave host and slave volume together are identifying Slave side). Also, it is possible to create both root and non-root geo-rep session between same Master volume and Slave volume. This should also be avoided. Solution: This multiple geo-rep session creation must be avoided and in order to avoid, use Slave volume uuid to identify a Slave. This way, we can identify whether a session is already created for the same Slave volume and avoid creating again (using different host). When the session creation is forced in the above scenario, rename the existing geo-rep session directory with new Slave Host mentioned.

* all: reduce "inline" usageJeff Darcy2015-09-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | There are three kinds of inline functions: plain inline, extern inline, and static inline. All three have been removed from .c files, except those in "contrib" which aren't our problem. Inlines in .h files, which are overwhelmingly "static inline" already, have generally been left alone. Over time we should be able to "lower" these into .c files, but that has to be done in a case-by-case fashion requiring more manual effort. This part was easy to do automatically without (as far as I can tell) any ill effect. In the process, several pieces of dead code were flagged by the compiler, and were removed.

* glusterd: initialize the daemon services on demandAtin Mukherjee2015-07-271-54/+13
| | | | | | | | | | | | | | | | | | | | | | As of now all the daemon services are initialized at glusterD init path. Since socket file path of per node daemon demands the uuid of the node, MY_UUID macro is invoked as part of the initialization. The above flow breaks the usecases where a gluster image is built following a template could be Dockerfile, Vagrantfile or any kind of virtualization environment. This means bringing instances of this image would have same UUIDs for the node resulting in peer probe failure. Solution is to lazily initialize the services on demand.

| | | | | | | | | | | | | | | | | | | | | | | | | | | GlusterD or a brick would crash when encrypted transport was enabled and an unencrypted client tried to connect to them. The crash occured when GlusterD/server tried to remove the transport from their xprt_list due to a DISCONNECT event. But as the client transport's list head wasn't inited, the process would crash when list_del was performed. Initing the client transports list head during acceptence, prevents this crash. Also, an extra check has been added to the GlusterD and Server notification handlers for client DISCONNECT events. The handlers will now first check if the client transport is a member of any list. GlusterD and Server DISCONNECT event handlers could be called without the ACCEPT handler, which adds the transport to the list, being called. This situation also occurs when an unencrypted client tries to establish a connection with an encrypted server.

* glusterd: Fix management encryption issues with GlusterDKaushal M2015-07-091-8/+5
| | | | | | | | | | | | | | | | | | | | | | | | | Management encryption was enabled incorrectly in GlusterD leading to issues of cluster deadlocks. This has been fixed with this commit. The fix is in two parts, 1. Correctly enable encrytion for the TCP listener in GlusterD and re-enable own-threads for encrypted connections. Without this, GlusterD could try to esatblish the blocking SSL connects in the epoll thread, for eg. when handling friend updates, which could lead to cluster deadlocks. 2. Explicitly enable encryption for outgoing peer connections. Without enabling encryption explicitly for outgoing connections was causing SSL socket events to be handled in the epoll thread. Some events, like disconnects during peer detach, could lead to connection attempts to happen in the epoll thread, leading to deadlocks again.

* Avoid conflict between contrib/uuid and system uuidEmmanuel Dreyfus2015-04-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glusterfs relies on Linux uuid implementation, which API is incompatible with most other systems's uuid. As a result, libglusterfs has to embed contrib/uuid, which is the Linux implementation, on non Linux systems. This implementation is incompatible with systtem's built in, but the symbols have the same names. Usually this is not a problem because when we link with -lglusterfs, libc's symbols are trumped. However there is a problem when a program not linked with -lglusterfs will dlopen() glusterfs component. In such a case, libc's uuid implementation is already loaded in the calling program, and it will be used instead of libglusterfs's implementation, causing crashes. A possible workaround is to use pre-load libglusterfs in the calling program (using LD_PRELOAD on NetBSD for instance), but such a mechanism is not portable, nor is it flexible. A much better approach is to rename libglusterfs's uuid_* functions to gf_uuid_* to avoid any possible conflict. This is what this change attempts.

| | | | | | | | | | | | | | | | | | | | In function glusterd_dump_peer() it is copying "input_key" into "key" buffer without checking the length which might cause string_overflow overrun. Similar problem with other coverity issue. With this fix it will copy "input_key" into "key" buffer by maximum length of buffer.

* glusterd: statedump supportAtin Mukherjee2014-10-151-4/+219
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Although glusterd currently has statedump support but it doesn't dump its context information. Implementing glusterd_dump_priv function to export per-node glusterd information would be useful for debugging bugs. Once implemented, we could enhance sos-report to fetch this information. This would potentially reduce our time to root cause and data needed for debugability can be dumped gradually. Following is the main items of the dump list targeted in this patch : * Supported max/min op-version and current op-version * Information about peer list * Information about peer list involved while a transaction is going on (xaction_peers) * option dictionary in glusterd_conf_t * mgmt_v3_lock in glusterd_conf_t * List of connected clients * uuid of glusterd * A section of rpc related information like live connections and their statistics There are couple of issues which were found during implementation and testing phase: - xaction_peers of glusterd_conf_t was not initialized in init because of which traversing through this list head was crashing when there was no active transaction - gf_free was not setting the typestr to NULL if the the alloc count becomes 0 for a mem-type earlier allocated.

* snapview-server: register a callback with glusterd to get notificationsRaghavendra Bhat2014-09-081-0/+37
| | | | | | | | | | | | | | | * As of now snapview-server is polling (sending rpc requests to glusterd) to get the latest list of snapshots at some regular time intervals (non configurable). Instead of that register a callback with glusterd so that glusterd sends notifications to snapd whenever a snapshot is created/deleted and snapview-server can configure itself.
