* rpc: duplicate request cache for nfsRajesh Amaravathi2013-06-211-22/+22
| | | | | | | | | | | | | | | 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.

* nfs: Unable to resolve FHRajesh Joseph2013-05-241-10/+8
| | | | | | | | | | | | | | | | | | | | Bug (965435): while deleting files/directory from multiple machines nfs server logs show "Unable to resolve FH" error. Cause: The error is shown whenever the server receives rmdir/remove call and the file/directory is already deleted. Server always shows "Unable to resolve FH" irrespective of what is the actual error. Fix: The error message seems little misleading therefore changed the error message to display the actual cause.

* nfs: handle stable write with @flags rather than fsync()Anand Avati2013-03-201-67/+26
| | | | | | | | | | | | | | | stable writes can be "made stable" by simply setting O_SYNC (or O_DSYNC, accordingly) in the write flags or fd->flags. Performing fsync() at the end of the write is extremely inefficient and completely messes up eager-locking logic in AFR.

* nfs: opendir/closedir for every readdirAnand Avati2010-11-151-13/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Revert "nfs3: Unref & unbind dir fd with inode lock on EOF" This reverts commit 4e6fb304ce41acbaf7c9ba67c06bf443e65082e8. The above commit (which unbinds fds at EOF) does not fix the original bug (1619) because a readdir from a second app could have already started before the readdir_cbk of the first app's readdir reaches NFS code. Hence the race still exists. Performing extra unrefs when EOF is received is not a reliable way of detecting that a client has performed a closedir (and to close the fd ourselves). Neither is interpreting a 0 cookies a new opendir. Clients can always use telldir/seekdir and hit EOFs twice. Due to the way NFS3 protocol is designed, it is just not possible for the server to reliably detect opendirs/closedirs performed by the client and map the corresponding readdirs to the same dir fd on the server side. The only reliable way of fixing this is to perform opendir/closedir at the cost of performance. Any optimization towards keeping dir fds open attempting to map them with application's opendir/closedir will either result in fd leaks or extra fd unrefs. Signed-off-by: Anand V.

* nfs: avoid assignment of structure pointer into serialized bufferAnand Avati2010-10-121-2/+4
| | | | | | | | | | | | | With the introduction of variable sized file handle feature in NFS, on-wire lengths of file handles can be lesser than file handle structure of code. Direct pointer assignment into the offsetted buffer and dereference and result in reads beyond the end of buffer and crashes. Signed-off-by: Anand V.
