* nfs3: Unref dir fd once usage ends in hard fh resolutionShehjar Tikoo2010-08-311-3/+29
| | | | | | | | | | | | | | | | | | There are three conditions when a dir fd_t needs to be unrefed when: a. the inode being searched is found as the candidate entry, b. we have exhausted all the entries in the current dir, c. we decide to step into a child directory because of a hash match. This decision is made in nfs3_fh_resolve_check_response.

* 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.

* nfs3: Round-up read reply bytes of multi-vector replyShehjar Tikoo2010-05-101-3/+1
| | | | | | | | | | | | | | | | | A previos commit brought in support for returning read replies when subvolumes return reads in multiple iovecs. This did not completely fix the problem since the bytes in iovecs all together could be unaligned with the 4 byte boundary as needed by XDR for the opaque data. This resulted in read requests being either retransmitted or rejected with an error message in syslog on the NFS client.

* nfs: Redesign fop argument passing to support single volfile useShehjar Tikoo2010-04-021-20/+20
| | | | | | | | | | | | | | | | | | | | | The current design of the interaction between the generic NFS layer and the protocol handlers like mount3 and nfs3 is such that it does not allow using a single volume file which contains the nfs/server and the protocol/server. This is because the common nfs-fops layer assumes that ctx->top is always the nfs/server. This is wrong. The fops layer needs access to top because top or rather the generic NFS xlator's private state has a mem-pool. The fops layer needs this mem-pool to get memory for storing per-fop state. Since the fops layer cannot anymore take ctx->top be the nfs/server, all layers need to start passing the nfs/server xlator_t right down to the fops layer. I am also taking this chance to remove the synchronous equivalents of the fops and also remove the dirent caching directory operations.
