* Replace GPLV3 MD5 with OpenSSL MD5Kaleb KEITHLEY2012-04-042-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ric asked me to look at replacing the GPL licensed MD5 code with something better, i.e. perhaps faster, and with a less restrictive license, etc. So I took a couple hour holiday from working on wrapping up the client_t and did this. OpenSSL (nee SSLeay) is released under the OpenSSL license, a BSD/MIT style license. OpenSSL (libcrypto.so) is used on Linux, OS X and *BSD, Open Solaris, etc. IOW it's universally available on the platforms we care about. It's written by Eric Young (eay), now at EMC/RSA, and I can say from experience that the OpenSSL implementation of MD5 (at least) is every bit as fast as RSA's proprietary implementation (primarily because the implementations are very, very similar.) The last time I surveyed MD5 implementations I found they're all pretty much the same speed. I changed the APIs (and ABIs) for the strong and weak checksums. Strictly speaking I didn't need to do that. They're only called on short strings of data, i.e. pathnames, so using int32_t and uint32_t is ostensibly okay. My change is arguably a better, more general API for this sort of thing. It's also what bit me when gerrit/jenkins validation failed due to glusterfs segv-ing. (I didn't pay close enough attention to the implementation of the weak checksum. But it forced me to learn what gerrit/jenkins are doing and going forward I can do better testing before submitting to gerrit.)

* protocol/server: send forget on the renamed inodeRaghavendra Bhat2012-03-181-0/+28
| | | | | | | | | | | | | | | | | | | | If rename is given on a file "a" to "b" ("b" is already existing file), then after rename, the inode for "b" would still be in the inode table and would not get forget (for fuse client, the fuse kernel module would send, but on server forget will not come on that inode), thus leading to inode leak even when the mount point is empty. To avoid that before doing inode rename, unlink the previous inode that "b" is pointing to and send forget on that, if "b" is the last dentry for that inode.

* protocol/server: add and remove the transports from the list, inside the lockRaghavendra Bhat2012-03-172-26/+54
| | | | | | | | | | | | | | | | | | | | | | | Till now for graph changes, glusterfs client used to remember the old graph also. Hence the transport object on the server corresponding the old graph never received disconnect. But now since the graph cleanup is happening, transport on the server side gets disconnect for the cleaned up graph. Server maintains, all the transports in a list. But addition of the new transport to the list, or removal of the transport from the list is not happening within the lock. Thus if a thread is accessing a transport (in cases of statedump, where each transprt's information is dumped), and the server gets a disconnect on that transport, then it leads to segfault of the process. To avoid it do the list (of transports) manipulation inside the lock.

| | | | | | | | | | | | | | | | | | | | | | | | 1) Adding the connection to conf->conns used to happen in conf->mutex, but removing happened under conn->lock. Fixed that as below. When the connection object is created conn's ref, bind_ref count is set to '1'. For bind_ref ref/unref happens under conf->mutex whenever server_connection_get, put is called. When bind_ref goes to '0' connection object is removed from conf->conns under conf->mutex. After it is removed from the list, conn_unref is called outside the conf->mutex. conn_ref/unref still happens under conn->lock. 2) Fixed races in server_connection_cleaup in grace_timer_handler and server_setvolume.

| | | | | | | | | | | | | | | | | | | | | | | Till now, send and recieve buffer window sizes for sockets were set to a default glusterfs-specific value. Linux's default window sizes have been found to be better w.r.t performance, and hence, no more setting it to any default value. However, if one wishes, there's the new configuration option: network.tcp-window-size <sane_size> which takes a size value (int or human readable) and will set the window size of sockets for both clients and servers. Nfs clients will also be updated with the same.

* protocol/client,server: fcntl lock self healing.Mohammed Junaid2012-02-206-21/+213
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
