* Replace GPLV3 MD5 with OpenSSL MD5Kaleb KEITHLEY2012-04-046-43/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.)

Fix For symlinks getxattr now always winds to the first subvol and for directories setxattr sets the xattr on all subvols.

| | | | | | | | | | | | | | | in each translator, which uses 'frame->local', we are using GF_CALLOC/GF_FREE, which would be costly considering the number of allocation happening in a lifetime of 'fop'. It would be good to utilize the mem pool framework for xlator's local structures, so there is no allocation overhead.

* fuse-bridge: Handle graph-switch.Raghavendra G2012-02-214-2/+109
| | | | | | | | | | | | | | | | | The purpose of this patch is to let protocol/client know when its transports can be disconnected, without application running on gluster mount noticing any effects of graph switch. In order to do this, we migrate all fds and blocked locks to new graph. Once this migration is complete and there are no in-transit frames as viewed by fuse-bridge, we send a PARENT_DOWN event to its children. protocol/client on receiving this event, can disconnect up its transports.

* protocol/client,server: fcntl lock self healing.Mohammed Junaid2012-02-206-8/+552
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
