* fuse: revalidate group id cache on uid/gid change detectionAnand Avati2013-11-211-1/+3
| | | | | | | | | | | | | | | | | | | - Remember the uid and gid of the pid at the time of caching the group id list. - Next time when referring to the cache confirm that uid and gid of that pid has not changed since. If it has, treat it like a timeout/cache miss. - Solves group id caching issue caused when Samba runs on gluster FUSE mount and changes the uid/gid on a per syscall basis.

* gNFS: RFE for NFS connection behaviorSantosh Kumar Pradhan2013-11-141-0/+1
| | | | | | | | | | | | | | | Implement reconfigure() for NFS xlator so that volume set/reset wont restart the NFS server process. But few options can not be reconfigured dynamically e.g. nfs.mem-factor, nfs.port etc which needs NFS to be restarted.

* libglusterfs,mount/fuse: implement gidcache mechanism in fuse-bridgeBrian Foster2012-07-171-0/+52
This change genericizes the cache mechanism implemented in commit 8efd2845 into libglusterfs/src/gidcache.[ch] and adds fuse-bridge as a client. The cache mechanism is fundamentally equivalent, with some minor changes: - Change cache key from uid_t to uint64_t. - Modify the cache add logic to locate and use an entry with a matching ID, should it already exist. This addresses a bug in the existing mechanism where an expired entry supercedes a newly added entry in lookup, causing repeated adds and flushing of a cache bucket. The fuse group cache is disabled by default. It can be enabled via the 'gid-timeout' fuse-bridge translator option and accompanying mount option (i.e., '-o gid-timeout=1' for a 1s entry timeout).
