* nfs3: Special-case the lookup for parent dir of rootShehjar Tikoo2010-06-011-7/+31
| | | | | | | | | | | | | | | | When a lookup request comes in for (rootfh, ".."), we need to handle it in a way that returns the attributes and handle of the root dir. Not doing so crashes nfsx because the inode table is not able to find a inode for the root's parent. This inode was being referenced in nfs3_lookup_parentdir_resume when filling a loc for the lookup fop. For the record, such a lookup request is sent by vmkernel.

| | | | | | | | | | | | | | | | | In the readdir reply for the root of the export, replace the ino and gen number for the . and .. entries with 1 and 0 respectively. On clients which inspect this field, the client will error out due to the change in inode number of the root directory when see for "." .. also needs to be replaced because we do not have a concept of the parent directory of root. The return of 1 and 0 is the same as the behaviour of: stat /.. command. Signed-off-by: Shehjar Tikoo <shehjart@gluster.com> Signed-off-by: Anand V.

* nfs: Introduce trusted-write and trusted-sync optionsShehjar Tikoo2010-05-213-6/+183
| | | | | | | | | | | | | | | | | | | | | | | | Introduces two new options: 1. nfs3.*.trusted-write: Forces UNSTABLE writes to return STABLE to NFS clients to prevent the clients from sending a COMMIT. STABLE writes are still handled in a sync manner and so are COMMITs if they're sent at all. 2. nfs3.*.trusted-sync: Forces all WRITEs and COMMITs to return STABLE return flags to NFS clients to avoid the overhead of STABLE writes, and COMMITs that follow UNSTABLE writes. This includes the trusted-write functionality. In addition to the trusted-write, it also writes STABLE writes in an UNSTABLE manner. Both violate the NFS protocol but allow better write perf in most configurations. Use with caution. Signed-off-by: Shehjar Tikoo <shehjart@gluster.com> Signed-off-by: Anand V.

| | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | There is a possibility of io-cache or read-ahead returning a read buffer that straddles two separate pages in ioc or ra, through two struct iovecs.

* nfs3: Use nfs3state in call_state to avoid getting from rpc requestShehjar Tikoo2010-04-132-1/+3
| | | | | | | | | | | | | | | | This change avoids having the nfs translator depend on the sanity of the rpcsvc_request_t type after NFS reply has been sent. This was a problem because the request structure is guaranteed to be invalid after the reply for the request has been submitted by the RPC program. NFS3 handler was ignoring this behaviour and accessing the private in request after reply submission resulting in access to corrupted data.

* nfs: Redesign fop argument passing to support single volfile useShehjar Tikoo2010-04-0210-1418/+475
| | | | | | | | | | | | | | | | | | | | | 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.
