2005-06-22[PATCH] NFS: Ensure that fstat() always returns the correct mtimeTrond Myklebust
Even if the file is open for writes. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2005-06-22[PATCH] NFS: Cleanup of caching code, and slight optimization of writes.Trond Myklebust
Unless we're doing O_APPEND writes, we really don't care about revalidating the file length. Just make sure that we catch any page cache invalidations. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2005-06-22[PATCH] NFS: Fix the file size revalidationTrond Myklebust
Instead of looking at whether or not the file is open for writes before we accept to update the length using the server value, we should rather be looking at whether or not we are currently caching any writes. Failure to do so means in particular that we're not updating the file length correctly after obtaining a POSIX or BSD lock. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2005-06-22[PATCH] NFSv4: Fix up races in nfs4_proc_setattr()Trond Myklebust
If we do not hold a valid stateid that is open for writes, there is little point in doing an extra open of the file, as the RFC does not appear to mandate this... Make setattr use the correct stateid if we're holding mandatory byte range locks. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2005-06-22[PATCH] NFS: Hide NFS server-generated readdir cookies from userlandOlivier Galibert
NFSv3 currently returns the unsigned 64-bit cookie directly to userspace. The following patch causes the kernel to generate loff_t offsets for the benefit of userland. The current server-generated READDIR cookie is cached in the nfs_open_context instead of in filp->f_pos, so we still end up work correctly under directory insertions/deletion.

2005-06-22[PATCH] RPC: kick off socket connect operations fasterChuck Lever
Make the socket transport kick the event queue to start socket connects immediately. This should improve responsiveness of applications that are sensitive to slow mount operations (like automounters). We are now also careful to cancel the connect worker before destroying the xprt. This eliminates a race where xprt_destroy can finish before the connect worker is even allowed to run. Test-plan: Destructive testing (unplugging the network temporarily). Connectathon with UDP and TCP. Hard-code impossibly small connect timeout.

2005-06-22[PATCH] RPC: TCP reconnects are too slowChuck Lever
When the network layer reports a connection close, the RPC task waiting to reconnect should be notified so it can retry immediately instead of waiting for the normal connection establishment timeout. This reverts a change made in 2.6.6 as part of adding client support for RPC over TCP socket idle timeouts. Test-plan: Destructive testing with NFS over TCP mounts.

2005-06-22[PATCH] RPC: Ensure rpc calls respects the RPC_NOINTR flagTrond Myklebust
For internal purposes, the rpc_clnt_sigmask() call is replaced by a call to rpc_task_sigmask(), which ensures that the current task sigmask respects both the client cl_intr flag and the per-task NOINTR flag. Problem noted by Jiaying Zhang. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2005-06-22[PATCH] NFSv4: Fix an Oops in the callback code.Trond Myklebust
The changeset "trond.myklebust@fys.uio.no|ChangeSet|20050322152404|16979" (RPC: Ensure XDR iovec length is initialized correctly in call_header) causes the NFSv4 callback code to BUG() due to an incorrectly initialized scratch buffer. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2005-06-22[PATCH] NFS: Cache the NFSv3 acls.Andreas Gruenbacher
Attach acls to inodes in the icache to avoid unnecessary GETACL RPC round-trips. As long as the client doesn't retrieve any acls itself, only the default acls of exiting directories and the default and access acls of new directories will end up in the cache, which preserves some memory compared to always caching the access and default acl of all files.

2005-06-22[PATCH] NFS: Fix handling of the umask when an NFSv3 default acl is present.Andreas Gruenbacher
NFSv3 has no concept of a umask on the server side: The client applies the umask locally, and sends the effective permissions to the server. This behavior is wrong when files are created in a directory that has a default ACL. In this case, the umask is supposed to be ignored, and only the default ACL determines the file's effective permissions. Usually its the server's task to conditionally apply the umask. But since the server knows nothing about the umask, we have to do it on the client side. This patch tries to fetch the parent directory's default ACL before creating a new file, computes the appropriate create mode to send to the server, and finally sets the new file's access and default acl appropriately. Many thanks to Buck Huppmann <buchk@pobox.com> for sending the initial version of this patch, as well as for arguing why we need this change.

2005-06-22[PATCH] NFS: Add support for NFSv3 ACLsAndreas Gruenbacher
This adds acl support fo nfs clients via the NFSACL protocol extension, by implementing the getxattr, listxattr, setxattr, and removexattr iops for the system.posix_acl_access and system.posix_acl_default attributes. This patch implements a dumb version that uses no caching (and thus adds some overhead). (Another patch in this patchset adds caching as well.)

Currently we return -ENOMEM for every single failure to create a new auth. This is actually accurate for auth_null and auth_unix, but for auth_gss it's a bit confusing.
