gNFS: Make NFS DRC off by default

2014-06-09T07:27:07+00:00

DRC in NFS causes memory bloat and there are known memory corruptions.
It would be good to disable drc by default till the feature is stable.

gNFS: gNFS drc cache failed to detecte duplicates.

2014-04-28T07:50:24+00:00

After the drc cache get full, message "DRC failed to detect duplicates" keep
printed in the log.
The root cause is drc_compare_reqs use the wrong compare type. This function
should use type drc_cache_op_t as its input type. Since all rbtree related code
(except function rpcsvc_drc_lookup) in drc cache pass drc_cache_op_t as compare
type. Only rpcsvc_drc_lookup use type rpcsvc_request_t. It has been modified
too.

gNFS: Small memory leak in rpcsvc_drc_init()

2014-01-04T06:17:35+00:00

1. The routine rpcsvc_drc_init() is only used while initialization of
NFS xlator. It should just check for nfs.drc option and init DRC feature
accordingly. If it's set to OFF, then rpcsvc_drc_init() allocates memory
for svc.drc and set ret value to 0 and goes to out: block where drc is
leaked.

2. rpcsvc_drc_init() should just allocate svc.drc and init it. Here
svc.drc can never be valid.

3. If svc.drc gets init'd here, no point of checking for drc type here.

gNFS: More clean up for Gluster NFS

2013-11-25T13:40:57+00:00

1) Fix the typo in NFS default ACL
   The typo was introduced as part of the Fix to BZ 1009210 i.e.
   http://review.gluster.org/5980. The user ACL xattr structure
   was passed to default ACL xattr.

2) Clean up NFS code to avoid unnecessary SEGV in
   rpcsvc_drc_reconfigure() which was not validating the
   svc->drc. Add a routine rpcsvc_drc_deinit() to handle
   the clean up of DRC specific data structures. For init(),
   use rpcsvc_drc_init().

3) nfs_init_state() was returning wrong value even if the
   registration with portmapper failed, causing the NFS
   server process to hang around. As a result it used to
   get SEGV during rpcsvc_drc_reconfigure().

4) Clean up memfactor usage across nfs.c nfs3.c.

gNFS: RFE for NFS connection behavior

2013-11-15T00:07:02+00:00

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.

rpc: duplicate request cache for nfs

2013-06-21T17:33:49+00:00

Duplicate request cache provides a mechanism for detecting
duplicate rpc requests from clients. DRC caches replies
and on duplicate requests, sends the cached reply instead of
re-processing the request.
