* protocol/server: forget the inodes which got ENOENT in lookupRaghavendra Bhat2015-08-202-22/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | If a looked up object is removed from the backend, then upon getting a revalidated lookup on that object ENOENT error is received. protocol/server xlator handles it by removing dentry upon which ENOENT is received. But the inode associated with it still remains in the inode table, and whoever does nameless lookup on the gfid of that object will be able to do it successfully despite the object being not present. For handling this issue, upon getting ENOENT on a looked up entry in revalidate lookups, protocol/server should forget the inode as well. Though removing files directly from the backend is not allowed, in case of objects corrupted due to bitrot and marked as bad by scrubber, objects are removed directly from the backend in case of replicate volumes, so that the object is healed from the good copy. For handling this, the inode of the bad object removed from the backend should be forgotten. Otherwise, the inode which knows the object it represents is bad, does not allow read/write operations happening as part of self-heal.

* rpc: add owner xlator argument to rpc_clnt_newKrishnan Parthasarathi2015-08-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* rpc: fix concurrency bug in gf_authenticateJeff Darcy2015-07-281-47/+31
| | | | | | | | | | | | | | | | | | | | | The basic problem is that gf_authenticate abused global variables to pass info through dict_foreach. This is not thread-safe, but it wasn't affecting most people until multi-threaded epoll came along. Now, if two threads get into this code at the same time - and there's nothing to prevent it - one of them could free one of the dicts involved while the other is still using it. The fix is to pass this same information using a temporary structure instead of globals. This makes the code smaller and more efficient too.

* rpc,server,glusterd: Init transport list for accepted transportKaushal M2015-07-241-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* protocol/server: use different dict for resolvingRaghavendra Bhat2015-07-151-2/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | protocol/server has to resolve the inode before continuing with any fop coming from the clients. For resolving it, server xlator was using the same dict associated with the fop. It causes problems in some situations. If a directory's inode was forgotten because of lru limit being exceeded, then when a create fop comes for an entry within that directory, server tries to resolve it. But since the parent directory's inode is not found in the inode table, it tries to do a hard resolve by doing a lookup on the parent gfid. If any xlator below server wants to get some extended attributes whenever lookup comes, then they set the new keys in the same dict that came along with the create fop. Now, the lookup of the parent succeeds and the create fop proceeds with the same dict (with extra keys present). posix xlaror creates those xattrs that are present in the dict. Thus the xattrs which were not to be present by default are also set as part of create. (Ex: bit-rot related xattrs such as bad-file, version and sign xattrs) Change-Id: I4bdad175a1d7a04a3aa36073667c556d6c260263 Signed-off-by: Raghavendra Bhat <raghavendra@redhat.com> Reviewed-on: http://review.gluster.org/11661 Reviewed-by: Vijaikumar Mallikarjuna <vmallika@redhat.com> Tested-by: NetBSD Build System <jenkins@build.gluster.org> Reviewed-by: Raghavendra G <rgowdapp@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Avoid conflict between contrib/uuid and system uuidEmmanuel Dreyfus2015-04-044-75/+75
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* core: Add inode context merge callbackVenky Shankar2015-03-241-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Certain translators may require to update the inode context of an already linked inode before unwinding the call to the client. Normally, such a case in encountered during parallel operations when a fresh inode is chosen at call (wind) time. In the callback path, one of inodes is successfully linked in the inode table, thereby the other inodes being thrown away (and the inode pointers for these calls being pointed to the linked inode). Translators which may have strict dependency on the correct value in the inode context would get stale values in inode context. This patch introduces a new callback which provides gives translators an opportunity to "patch" their respective inode contexts. Note that, as of now, this callback is only invoked during create()s unwind path. Although this might needed to be done for all dentry fops and lookup, but let that be done as an when required (bitrot stub requires this *only* for create()).

* cluster/dht: Change the subvolume encoding in d_off to be a "global"Dan Lambright2015-03-185-6/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | position in the graph rather than relative (local) to a particular translator. Encoding the volume in this way allows a single translator to manage which brick is currently being scanned for directory entries. Using a single translator minimizes allocated bits in the d_off. It also allows multiple DHT translators in the same graph to have a common frame of reference (the graph position) for which brick is being read. Multiple DHT translators are needed for the Tiering feature. The fix builds off a previous change (9332) which removed subvolume encoding from AFR. The fix makes an equivalent change to the EC translator. More background can be found in fix 9332 and gluster-dev discussions [1]. DHT and AFR/EC are responsibile (as before) for choosing which brick to enumerate directory entries in over the readdir lifecycle. The client translator receiving the readdir fop encodes the dht_t. It is referred to as the "leaf node" in the graph and corresponds to the brick being scanned. When DHT decodes the d_off, it translates the leaf node to a local subvolume, which represents the next node in the graph leading to the brick. Tracking of leaf nodes is done in common utility functions. Leaf nodes counts and positional information are updated on a graph switch.

* every/where: add GF_FOP_IPC for inter-translator communicationJeff Darcy2015-03-173-47/+264
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several features - e.g. encryption, erasure codes, or NSR - involve multiple cooperating translators which sometimes need a "private" means of communication amongst themselves. Historically we've used virtual or synthetic xattrs, but that's not very elegant and clutters up the getxattr/setxattr path which must also handle real xattr requests. This new fop should address that. The only argument is an int32_t "op" which should be recognized by the target translator. It is recommended that translators using these feature follow some convention regarding the ops that they define, to avoid conflicts. Using a hash of the target translator's type string as a base for a series of ops would probably be a good start. Any other information can be passed in both directions using xdata. The default behavior for this fop, as with any other, is to pass through to FIRST_CHILD. That makes use of this fop "transparent" to other translators that were written before it existed, but it also means that it only really works with pass-through translators. If a routing translator (such as DHT) or a fan-out translator (such as AFR) is involved, the IPC might not reach its intended destination unless those translators are modified to forward IPC fops along all paths. If an IPC gets all the way to storage/posix it is considered an error, much like an uncaught exception. We don't actually *do* anything in that case, but we do log it send back an EOPNOTSUPP error. This makes the "unrecognized opcode" condition distinguishable from the "no IPC support" condition (which would yield an RPC error instead) so clients can probe for the presence of a handler for their own favorite opcode and either use that or use old-school xattrs depending on the result.

* socket: use TCP_USER_TIMEOUT to detect client failures quickerNiels de Vos2015-03-171-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Use the network.ping-timeout to set the TCP_USER_TIMEOUT socket option (see 'man 7 tcp'). The option sets the transport.tcp-user-timeout option that is handled in the rpc/socket layer on the protocol/server side. This socket option makes detecting unclean disconnected clients more reliable. When the socket gets closed, any locks that the client held are been released. This makes it possible to reduce the fail-over time for applications that run on systems that became unreachable due to a network partition or general system error client-side (kernel panic, hang, ...). It is not trivial to create a test-case for this at the moment. We need a client that unclean disconnects and an other client that tries to take over the lock from the disconnected client.

Without establishing a total ordering of events, we can't guarantee that cluster xlators like afr, dht perceive them in the same order. While we would expect afr (say) to perceive it as only one of Brick1 and Brick2 going down at any given time, it is possible for the notification of Brick2 going offline to race with the notification of Brick1 coming back online.
