* 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/cli: cli to get local state representation from glusterdSamikshan Bairagya2016-08-261-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently there is no existing CLI that can be used to get the local state representation of the cluster as maintained in glusterd in a readable as well as parseable format. The CLI added has the following usage: # gluster get-state [daemon] [odir <path/to/output/dir>] [file <filename>] This would dump data points that reflect the local state representation of the cluster as maintained in glusterd (no other daemons are supported as of now) to a file inside the specified output directory. The default output directory and filename is /var/run/gluster and glusterd_state_<timestamp> respectively. The option for specifying the daemon name leaves room to add support for other daemons in the future. Following are the data points captured as of now to represent the state from the local glusterd pov: * Peer: - Primary hostname - uuid - state - connection status - List of hostnames * Volumes: - name, id, transport type, status - counts: bricks, snap, subvol, stripe, arbiter, disperse, redundancy - snapd status - quorum status - tiering related information - rebalance status - replace bricks status - snapshots * Bricks: - Path, hostname (for all bricks these info will be shown) - port, rdma port, status, mount options, filesystem type and signed in status for bricks running locally. * Services: - name, online status for initialised services * Others: - Base port, last allocated port - op-version - MYUUID Change-Id: I4a45cc5407ab92d8afdbbd2098ece851f7e3d618 BUG: 1353156 Signed-off-by: Samikshan Bairagya <samikshan@gmail.com> Reviewed-on: http://review.gluster.org/14873 Reviewed-by: Avra Sengupta <asengupt@redhat.com> Smoke: Gluster Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Reviewed-by: Atin Mukherjee <amukherj@redhat.com>

* changelog/rpc: Fix rpc_clnt_t mem leaksKotresh HR2016-07-222-6/+99
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PROBLEM: 1. Freeing up rpc_clnt object might lead to crashes. Well, it was not a necessity to free rpc-clnt object till now because all the existing use cases needs to reconnect back on disconnects. Hence timer code was not taking ref on rpc-clnt object. Glusterd had some use-cases that led to crash due to ping-timer and they fixed only those code paths that involve ping-timer. Now, since changelog has an use-case where rpc-clnt need to be freed up, we need to fix timer code to take refs 2. In changelog, because of issue 1, only mydata was being freed which is incorrect. And there are races where rpc-clnt object would access the freed mydata which would lead to crashes. Since changelog xlator resides on brick side and is long living process, if multiple libgfchangelog consumers register to changelog and disconnect/reconnect mulitple times, it would result in leak of 'rpc-clnt' object for every connect/disconnect. SOLUTION: 1. Handle ref/unref of 'rpc_clnt' structure in timer functions properly. 2. In changelog, unref 'rpc_clnt' in RPC_CLNT_DISCONNECT after disabling timers and free mydata on RPC_CLNT_DESTROY. RPC SETUP IN CHANGELOG: 1. changelog xlator initiates rpc server say 'changelog_rpc_server' 2. libgfchangelog initiates one rpc server say 'libgfchangelog_rpc_server' 3. libgfchangelog initiates rpc client and connects to 'changelog_rpc_server' 4. In return changelog_rpc_server initiates a rpc client and connects back to 'libgfchangelog_rpc_server' REF/UNREF HANDLING IN TIMER FUNCTIONS: Let's say rpc clnt refcount = 1 1. Take the ref before reigstering callback to timer queue >>>> rpc_clnt_ref (say ref count becomes = 2) 2. Register a callback to timer say 'callback1' 3. If register fails: >>>> rpc_clnt_unref (ref count = 1) 4. On timer expiration, 'callback1' gets called. So unref rpc clnt at the end in 'callback1'. This is corresponding to ref taken in step 1 >>>> rpc_clnt_unref (ref count = 1) 5. The cycle from step-1 to step-4 continues....until timer cancel event happens 6. timer cancel of say 'callback1' If timer cancel fails: Do nothing, Step-4 would have unrefd If timer cancel succeeds: >>>> rpc_clnt_unref (ref count = 1) Change-Id: I91389bc511b8b1a17824941970ee8d2c29a74a09 BUG: 1316178 Signed-off-by: Kotresh HR <khiremat@redhat.com> Reviewed-on: http://review.gluster.org/13658 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: Raghavendra G <rgowdapp@redhat.com>

* glusterd: add defence mechanism to avoid brick port clashesPrasanna Kumar Kalever2016-05-041-40/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Intro: Currently glusterd maintain the portmap registry which contains ports that are free to use between 49152 - 65535, this registry is initialized once, and updated accordingly as an then when glusterd sees they are been used. Glusterd first checks for a port within the portmap registry and gets a FREE port marked in it, then checks if that port is currently free using a connect() function then passes it to brick process which have to bind on it. Problem: We see that there is a time gap between glusterd checking the port with connect() and brick process actually binding on it. In this time gap it could be so possible that any process would have occupied this port because of which brick will fail to bind and exit. Case 1: To avoid the gluster client process occupying the port supplied by glusterd : we have separated the client port map range with brick port map range more @ http://review.gluster.org/#/c/13998/ Case 2: (Handled by this patch) To avoid the other foreign process occupying the port supplied by glusterd : To handle above situation this patch implements a mechanism to return EADDRINUSE error code to glusterd, upon which a new port is allocated and try to restart the brick process with the newly allocated port. Note: Incase of glusterd restarts i.e. runner_run_nowait() there is no way to handle Case 2, becuase runner_run_nowait() will not wait to get the return/exit code of the executed command (brick process). Hence as of now in such case, we cannot know with what error the brick has failed to connect. This patch also fix the runner_end() to perform some cleanup w.r.t return values.

* protocol client/server: Fix client-server handshakeAvra Sengupta2016-03-101-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Currently on a successful connection between protocol server and client, the protocol client initiates a CHILD_UP event in the client stack. At this point in time, only the connection between server and client is established, and there is no guarantee that the server side stack is ready to serve requests. It works fine now, as most server side translators are not dependent on any other factors, before being able to serve requests today and hence they are up by the time the client stack translators receive the CHILD_UP (initiated by client handshake). The gap here is exposed when certain server side translators like NSR-Server for example, have a couple of protocol clients as their child(connecting them to other bricks), and they can't really serve requests till a quorum of their children are up. Hence these translators should defer sending CHILD_UP till they have enough children up, and the same needs to be propagated to the client stack translators. Fix: Maintain a child_up variable in both the protocol client and protocol server translators. The protocol server should update this value based on the CHILD_UP and CHILD_DOWN events it receives from the translators below it. On receiving such an event it should forward that event to the client. The protocol client on receiving such an event should forward it up the client stack, thereby letting the client translators correctly know that the server is up and ready to serve. The clients connecting later(long after a server has initialized and processed it's CHILD_UP events), will receive a child_up status as part of the handshake, and based on the status of the server's child_up, can either propagate a CHILD_UP event or defer it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Glusterd not working using ipv6 transport. The idea is with proper glusterd.vol configuration, 1. glusterd needs to listen on default port (240007) as IPv6 TCP listner. 2. Volume creation/deletion/mounting/add-bricks/delete-bricks/peer-probe needs to work using ipv6 addresses. 3. Bricks needs to listen on ipv6 addresses. All the above functionality is needed to say that glusterd supports ipv6 transport and this is broken. Fix: When "option transport.address-family inet6" option is present in glusterd.vol file, it is made sure that glusterd creates listeners using ipv6 sockets only and also the same information is saved inside brick volume files used by glusterfsd brick process when they are starting.

* server/protocol: option for dynamic authorization of client permissionsPrasanna Kumar Kalever2015-10-042-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | problem: assuming gluster volume is already mounted (for gfapi: say client transport connection has already established), now if somebody change the volume permissions say *.allow | *.reject for a client, gluster should allow/terminate the client connection based on the fresh set of volume options immediately, but in existing scenario neither we have any option to set this behaviour nor we take any action until and unless we remount the volume manually solution: Introduce 'dynamic-auth' option (default: on). If 'dynamic-auth' is 'on' gluster will perform dynamic authentication to allow/terminate client transport connection immediately in response to *.allow | *.reject volume set options, thus if volume permissions have changed for a particular client (say client is added to auth.reject list), his transport connection to gluster volume will be terminated immediately.

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.

* rpc: add owner xlator argument to rpc_clnt_newKrishnan Parthasarathi2015-08-122-2/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The structure 'rpcsvc_state', which maintains rpc server state had no separate pointer to track the translator. It was using the mydata pointer itself. So callers were forced to send xlator pointer as mydata which is opaque (void pointer) by function prototype. 'rpcsvc_register_init' is setting svc->mydata with xlator pointer. 'rpcsvc_register_notify' is overwriting svc->mydata with mydata pointer. And rpc interprets svc->mydata as xlator pointer internally. If someone passes non xlator structure pointer to rpcsvc_register_notify as libgfchangelog currently does, it might corrupt mydata. So interpreting opaque mydata as xlator pointer is incorrect as it is caller's choice to send mydata as any type of data to 'rpcsvc_register_notify'. Maintaining two different pointers in 'rpcsvc_state' for xlator and mydata solves the issue.

* 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.
