* protocol client/server: Fix client-server handshakeAvra Sengupta2016-03-105-11/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* protocol/client: give preference to loc->gfid over inode->gfidRavishankar N2015-10-131-6/+6
| | | | | | | | | | | | | | | | | | There are xlators which perform fops even before inode gets linked. Because of this loc.gfid is preferred at the time of inodelk/entrylk but by the time unlock can happen, inode could be linked with a different gfid than the one in loc.gfid (because of the way dht was giving preference) Due to this unlock goes on a different inode than the one we sent inodelk on, which leads to hang.

| | | | | | | | | | | | | | | | | | | | Normally GF_EVENT_CHILD_UP is dispatched after client handshake. But we have some dead code in client_rpc_notify which is assumed to do the same on receiving RPC_CLNT_CONNECT. This dispatch is based on a condition whether "disable-handshake" is enabled or not. Since we require client-handshake everytime we have a connect this check for "disable-handshake" is invalid and no longer required. Moreover this option is never handled in any of the translators.

* build: export minimum symbols from xlators for correct resolutionKaleb S. KEITHLEY2015-09-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | We've been lucky that we haven't had any symbol collisions until now. Now we have a collision between the snapview-client's svc_lookup() and libntirpc's svc_lookup() with nfs-ganesha's FSAL_GLUSTER and libgfapi. As a short term solution all the snapview-client's FOP methods were changed to static scope. See http://review.gluster.org/11805. This works in snapview-client because all the FOP methods are defined in a single source file. This solution doesn't work for other xlators with FOP methods defined in multiple source files. To address this we link with libtool's '-export-symbols $symbol-file' (a wrapper around `ld --version-script ...` --- on linux anyway) and only export the minimum required symbols from the xlator sharedlib. N.B. the libtool man page says that the symbol file should be named foo.sym, thus the rename of *.exports to *.sym. While foo.exports worked, we will follow the documentation. Signed-off-by: Kaleb S.

* protocol-client/server: Fix incorrect grace-timeout value in logsAnoop C S2015-09-032-21/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When grace-timer is initialized via server/client init, the default or reconfigured value for grace-timeout is displayed incorrectly in both server and client logs. This is because we use gf_time_fmt() to format this grace-timeout value with gf_timefmt_s as the time format as shown below: gf_time_fmt (timestr, sizeof timestr, conf->grace_ts.tv_sec, gf_timefmt_s); gf_timefmt_s format is a wrapper for %s format specification used in strftime library call which populates the number of seconds since the Epoch [1970-01-01 00:00:00 +0000 (UTC)]. But this particular format is dependent on timezone [1970-01-01 05:30:00 +0530 (IST)]and thus displayed incorrectly in logs. Example: For IST with default grace-timeout value 10, it is displayed as -19790 which is calculated as follows, 1970-01-01 00:00:10 - 1970-01-01 05:30:00 = -19790 seconds.

* 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.

* Avoid conflict between contrib/uuid and system uuidEmmanuel Dreyfus2015-04-042-62/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* cluster/dht: Change the subvolume encoding in d_off to be a "global"Dan Lambright2015-03-185-6/+30

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 Darcy2015-03-172-47/+170
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

With MT epoll, notification events from client xlators could reach cluster xlators like afr, dht, ec, stripe etc. in different orders. For e.g, In a distributed replicate volume of 2 bricks, namely Brick1 and Brick2, the following network events are observed by a mount process. - connection to Brick1 is broken. - connection to Brick1 has been restored. - connection to Brick2 is broken. - connection to Brick2 has been restored. 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the ability to configure the number of event threads for various gluster services. Currently with the multi thread epoll patch, it is possible to have more than one thread waiting on socket activity and processing the same. This thread count is currently static, which this commit makes dynamic. The current services which use IO path, i.e brick processes, any client process (nfs, FUSE, gfapi, heal, rebalance, etc.a), gain 2 set parameters to control the number of threads that are processing events. These settings are, - client.event-threads <n> - server.event-threads <n> The client setting affects the client graph consumers, and the server setting affects the brick processes. These are processed and inited/reconfigured using the client/server protocol xlators. Other services (say glusterd) would need to extend similar configuration settings to take advantage of multi threaded event processing. At present glusterd is not enabled with this commit, as it does not stand to gain from this multi-threading (as I understand it).

Plus a minor tweak to return a ptr to the dest-string to allow gf_time_fmt() to be passed as a param in a *printf().

So for tcp,rdma volume there will be an entry with '.rdma', but it will fail for rdma type only volume. So we will try again, this time without appending '.rdma' using a flag variable need_different_port, and it will succeed, but the reconnection happens only after 3 seconds. In this patch for rdma only type volume we will append '.rdma' during the pmap_signin. So during the handshake we will get the correct port for first try itself. Since we don't need to retry , we can remove the need_different_port flag variable.
