* protocol/client,server: fcntl lock self healing.Mohammed Junaid2012-02-201-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently(with out this patch), on a disconnect the server cleans up the transport which inturn closes the fd's and releases the locks acquired on those fd's by that client. On a reconnect, client just reopens the fd's but doesn't reacquire the locks. The application that had previously acquired the locks still is under the assumption that it is the owner of those locks which might have been granted to other clients(if they request) by the server leading to data corruption. This patch allows the client to reacquire the fcntl locks (held on the fd's) during client-server handshake. * The server identifies the client via process-uuid-xl (which is a combination of uuid and client-protocol name, it is assumed to be unique) and lk-version number. * The client maintains a list of process-uuid-xl, lk-version pair for each accepted connection. On a connect, the server traverses the list for a matching pair, if a matching pair is not found the the server returns lk-version with value 0, else it returns the lk-version it has in store. * On a disconnect, the server and client enter grace period, and on the completion of the grace period, the client bumps up its lk-version number (which means, it will reacquire the locks the next time) and the server will distroy the connection. If reconnection happens within the grace period, the server will find the matching (process-uuid-xl, lk-version) pair in its list which guarantees that the fd's and there corresponding locks are still valid for this client. Configurable options: To set grace-timeout, the following options are option server.grace-timeout value option client.grace-timeout value To enable or disable the lk-heal, option lk-heal [on|off] gluster volume set command can be used to configurable options Change-Id: Id677ef1087b300d649f278b8b2aa0d94eae85ed2 BUG: 795386 Signed-off-by: Mohammed Junaid <junaid@redhat.com> Reviewed-on: http://review.gluster.com/2766 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Vijay Bellur <vijay@gluster.com>

* glusterd: auth allow enhancementsRajesh Amaravathi2012-02-2014-144/+538
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * PROBLEM: When address-based authentication is enabled on a volume, the gNfs server, self-heal daemon (shd), and other operations such as quota, rebalance, replace-brick and geo-replication either stop working or the services are not started if all the peers' ipv{4,6} addresses or hostnames are not added in the "set auth.allow" operation, breaking the functionality of several operations. E.g: volume vol in a cluster of two peers: /mnt/brick1 in 192.168.1.4 /mnt/brick2 in 192.168.1.5 option auth.allow 192.168.1.6 (allow connection requests only from 192.168.1.6) This will disrupt the nfs servers on 192.168.1.{4,5}. brick server processes reject connection requests from both nfs servers (on 4,5), because the peer addresses are not in the auth.allow list. Same holds true for local mounts (on peer machines), self-heal daemon, and other operations which perform a glusterfs mount on one of the peers. * SOLUTION: Login-based authentication (username/password pairs, henceforth referred to as "keys") for gluster services and operations. These *per-volume* keys can be used to by-pass the addr-based authentication, provided none of the peers' addresses are put in the auth.reject list, to enable gluster services like gNfs, self-heal daemon and internal operations on volumes when auth.allow option is exercised. * IMPLEMENTATION: 1. Glusterd generates keys for each volume and stores it in memory as well as in respective volfiles. A new TRUSTED-FUSE volfile is generated which is fuse volfile + keys in protocol/client, and is named trusted-<volname>-fuse.vol. This is used by all local mounts. ANY local mount (on any peer) is granted the trusted-fuse volfile instead of fuse volfile via getspec. non-local mounts are NOT granted the trusted fuse volfile. 2. The keys generated for the volume is written to each server volfile telling servers to allow users with these keys. 3. NFS, self-heal daemon and replace-brick volfiles are updated with the volume's authentication keys. 4. The keys are NOT written to fuse volfiles for obvious reasons. 5. The ownership of volfiles and logfiles is restricted to root users. 6. Merging two identical definitions of peer_info_t in auth/addr and rpc-lib, throwing away the one in auth/addr. 7. Code cleanup in numerous places as appropriate. * IMPORTANT NOTES: 1. One SHOULD NOT put any of the peer addresses in the auth.reject list if one wants any of the glusterd services and features such as gNfs, self-heal, rebalance, geo-rep and quota. 2. If one wants to use username/password based authentication to volumes, one shall append to the server, nfs and shd volfiles, the keys one wants to use for authentication, *while_retaining those_generated_by_glusterd*. See doc/authentication.txt file for details.

| | | | | | | | | | | | | | | | | | | | | | | This patch enables gluster cli to output data in xml format. XML output can be obtained by passing "--xml" as an argument. A new "volume list" command, which lists the volumes present in a cluster, has been added. This can be used for obtaining a quick list of volumes. Several commands, including "volume top", "volume profile", "volume status" and "volume info", "volume list", have custom XML output routines. Other commands use either one of the 2 generic output routines, cli_xml_output_str() & cli_xml_output_dict(). NOTE: When using "all" for "volume status" and "volume info" the XML output will have multiple roots.

| | | | | | | | | | | | | | | | | | | | | | | to op_sm Today if an rpc call made inside an op_sm can fail due to a disconnected peer, resulting in the rpc callback to be called in the same stack with appropriate status set. All glusterd rpc cbks move the state machine based on the status returned by the rpc layer, which would result in a nested call to op_sm. With the current scheme of locking, glusterd would end up in a deadlock situation The new scheme will fail the nested glusterd_op_sm (). This prevents the deadlock. It would work without any change in overall behaviour, as the current op_sm () call in execution wouldn't return until all events in the queue are processed.
