* rpc: changes to glusterfs programs that can take an optional payload argument.Raghavendra G2010-08-063-29/+44
| | | | | | | | | | | | | | | - The existing interface required the transport to separate the procedure header and procedure payload into two different buffers. Making this separation can prove cumbersome for transports like rdma wherein the header and payload can be received in a single buffer (For eg., header and payload of write fop sent as inline msg using rdma-send). This patch delegates the responsiblity of separating out header and payload to programs. Signed-off-by: Raghavendra G <raghavendra@gluster.com> Signed-off-by: Anand V.

| | | | | | | | | | | | | | | | | | - use mem-pool for requests and saved_frames. - preserve the rpc_req structure till rpc invokes program's reply. This will enable us to store transport specific data that has to last till reply has come (eg., memory regions of chunk lists in case of rdma). - change signature of rpc_clnt_submit to accept rsphdr_vector and rsppayload_vector. The buffers pointed by these vectors will be from iobufs and these iobufs are added to an iobref which should also be passed as an arguement to rpc_clnt_submit.

* nfs3: NULL fdentry check before removing from fdcacheShehjar Tikoo2010-07-281-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | Suppose a file name 1 is created and some data is written to it. After this another 512 files are newly created and written to. When the the 513th file is created and an fd_t opened for it, it results in 1's fd_t being replaced in the fd-lru with 513th file's fd_t. This is the correct behaviour resulting in all refs getting unref from the fd_t of 1 and the fd and all related state being freed. But, in some workloads, some refs are still pending even after the fd_t is removed from LRU, resulting in the fd still being bound to the inode. In nfs3svc_remove_cbk, while removing the inode state, we also ensure that any fd_ts in the cache for this inode are also removed. While removing the fd_t, this situation where the fd_t has replaced with another, even while a ref remains on the fd_t, results in a crash in the fdcache_remove path in nfs3svc_remove_cbk. This happens because the fd_ctx_get results in a NULL value because the ctx was already deleted when this fd_t was removed from fd-lru earlier. This patch fixes the crash by introducing a NULL check.

* replicate: Set setxattr wait-count to child-count to avoid raceShehjar Tikoo2010-07-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | A race is seen during a compilebench load against NFS where a NFSv3 MKDIR is immediately followed by a LOOKUP on the new directory. By the time this lookup comes in, the setxattr issued by distribute for the mkdir has not returned yet from all the replicas. Since replicate returns a reply for setxattr after receiving reply only from one subvol, the MKDIR is unwound from distribute. When the LOOKUP is received at distribute, the setxattr has still not completed at the second replica, whereas that is where the lookup is sent by replicate. Finding that the xattr is missing from the dir, distribute returns ESTALE to NFS, which return NFS3ERR_STALE to nfs client. This patch changes replicate setxattr behaviour by forcing replicate to wait for all children rather than one to call back before unwinding the stack.
