* NFSv4: Follow a referralManoj Naik2006-06-09
| | | | | | | | | | | Respond to a moved error on NFS lookup by setting up the referral. Note: We don't actually follow the referral during lookup/getattr, but later when we detect fsid mismatch in inode revalidation (similar to the processing done for cloning submounts).

| | | | | | | | | | Separate out the function of revalidating the inode metadata, and revalidating the mapping.

* NFS: Fix a race in nfs_sync_inode()Trond Myklebust2006-03-20
| | | | | | | | | | | | | | | | | | | | | | | | | Kudos to Neil Brown for spotting the problem: "in nfs_sync_inode, there is effectively the sequence: nfs_wait_on_requests nfs_flush_inode nfs_commit_inode This seems a bit racy to me as if the only requests are on the ->commit list, and nfs_commit_inode is called separately after nfs_wait_on_requests completes, and before nfs_commit_inode start (say: by nfs_write_inode) then none of these function will return >0, yet there will be some pending request that aren't waited for." The solution is to search for requests to wait upon, search for dirty requests, and search for uncommitted requests while holding the nfsi->req_lock The patch also cleans up nfs_sync_inode(), getting rid of the redundant FLUSH_WAIT flag. It turns out that we were always setting it. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

* nfs: Use UNSTABLE + COMMIT for NFS O_DIRECT writesTrond Myklebust2006-03-20
| | | | | | | | | | | | | | | | | | Currently NFS O_DIRECT writes use FILE_SYNC so that a COMMIT is not necessary. This simplifies the internal logic, but this could be a difficult workload for some servers. Instead, let's send UNSTABLE writes, and after they all complete, send a COMMIT for the dirty range. After the COMMIT returns successfully, then do the wake_up or fire off aio_complete(). Test plan: Async direct I/O tests against Solaris (or any server that requires committed unstable writes). Reboot server during test. Based on an earlier patch by Chuck Lever <cel@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

* NFS: make direct write path generate write requests concurrentlyChuck Lever2006-03-20
| | | | | | | | | | | | | | | | | Duplicate infrastructure from direct read path that will allow write path to generate multiple write requests concurrently. This will enable us to add support for aio in this path. Temporarily we will lose the ability to do UNSTABLE writes followed by a COMMIT in the direct write path. However, all applications I am aware of that use NFS O_DIRECT currently write in relatively small chunks, so this should not be inconvenient in any way. Test plan: Millions of fsx-odirect ops.

* NFS: Cleanup of NFS write code in preparation for asynchronous o_directTrond Myklebust2006-03-20
| | | | | | | | | | | | | | | | | This patch inverts the callback hierarchy for NFS write calls. Instead of having the NFSv2/v3/v4-specific code set up the RPC callback ops, we allow the original caller to do so. This allows for more flexibility w.r.t. how to set up and tear down the nfs_write_data structure while still allowing the NFSv3/v4 code to perform error handling. The greater flexibility is needed by the asynchronous O_DIRECT code, which wants to be able to hold on to the original nfs_write_data structures after the WRITE RPC call has completed in order to be able to replay them if the COMMIT call determines that the server has rebooted.

* NFS: Make stat() return updated mtimes after a write()Trond Myklebust2006-01-06
| | | | | | | | | The SuS states that a call to write() will cause mtime to be updated on the file. In order to satisfy that requirement, we need to flush out any cached writes in nfs_getattr().

* NFS: support large reads and writes on the wireChuck Lever2006-01-06
| | | | | | | | | | | | | | | | | Most NFS server implementations allow up to 64KB reads and writes on the wire. The Solaris NFS server allows up to a megabyte, for instance. Now the Linux NFS client supports transfer sizes up to 1MB, too. This will help reduce protocol and context switch overhead on read/write intensive NFS workloads, and support larger atomic read and write operations on servers that support them.

* NFSv4: Fix problem with OPEN_DOWNGRADETrond Myklebust2005-11-04
| | | | | | | | | | | | | | | | | RFC 3530 states that for OPEN_DOWNGRADE "The share_access and share_deny bits specified must be exactly equal to the union of the share_access and share_deny bits specified for some subset of the OPENs in effect for current openowner on the current file. Setattr is currently violating the NFSv4 rules for OPEN_DOWNGRADE in that it may cause a downgrade from OPEN4_SHARE_ACCESS_BOTH to OPEN4_SHARE_ACCESS_WRITE despite the fact that there exists no open file with O_WRONLY access mode. Fix the problem by replacing nfs4_find_state() with a modified version of nfs_find_open_context(). Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFS: Don't let nfs_end_data_update() clobber attribute update informationTrond Myklebust2005-10-27
| | | | | | | | | | | | Since we almost always call nfs_end_data_update() after we called nfs_refresh_inode(), we now end up marking the inode metadata as needing revalidation immediately after having updated it. This patch rearranges things so that we mark the inode as needing revalidation _before_ we call nfs_refresh_inode() on those operations that need it.

| | | | | | | | | | | | | | | | | Each transport implementation can now set unique bind, connect, reestablishment, and idle timeout values. These are variables, allowing the values to be modified dynamically. This permits exponential backoff of any of these values, for instance. As an example, we implement exponential backoff for the connection reestablishment timeout. Test-plan: Destructive testing (unplugging the network temporarily). Connectathon with UDP and TCP.

* [PATCH] NFS: Introduce the use of inode->i_lock to protect fields in nfsiChuck Lever2005-08-18
| | | | | | | | | | | | | | | | | | | | Down the road we want to eliminate the use of the global kernel lock entirely from the NFS client. To do this, we need to protect the fields in the nfs_inode structure adequately. Start by serializing updates to the "cache_validity" field. Note this change addresses an SMP hang found by njw@osdl.org, where processes deadlock because nfs_end_data_update and nfs_revalidate_mapping update the "cache_validity" field without proper serialization. Test plan: Millions of fsx ops on SMP clients. Run Nick Wilson's breaknfs program on large SMP clients.

* [PATCH] NFS: use atomic bitops to manipulate flags in nfsi->flagsChuck Lever2005-08-18
| | | | | | | | | | | | | | | | | | | | | | | Introduce atomic bitops to manipulate the bits in the nfs_inode structure's "flags" field. Using bitops means we can use a generic wait_on_bit call instead of an ad hoc locking scheme in fs/nfs/inode.c, so we can remove the "nfs_i_wait" field from nfs_inode at the same time. The other new flags field will continue to use bitmask and logic AND and OR. This permits several flags to be set at the same time efficiently. The following patch adds a spin lock to protect these flags, and this spin lock will later cover other fields in the nfs_inode structure, amortizing the cost of using this type of serialization.

* [PATCH] NFS: Ensure we always update inode->i_mode when doing O_EXCL createsTrond Myklebust2005-08-16
| | | | | | | | | | | | | | | | | | | When the client performs an exclusive create and opens the file for writing, a Netapp filer will first create the file using the mode 01777. It does this since an NFSv3/v4 exclusive create cannot immediately set the mode bits. The 01777 mode then gets put into the inode->i_mode. After the file creation is successful, we then do a setattr to change the mode to the correct value (as per the NFS spec). The problem is that nfs_refresh_inode() no longer updates inode->i_mode, so the latter retains the 01777 mode. A bit later, the VFS notices this, and calls remove_suid(). This of course now resets the file mode to inode->i_mode & 0777. Hey presto, the file mode on the server is now magically changed to 0777. Duh...

* [PATCH] NFS: Fix handling of the umask when an NFSv3 default acl is present.Andreas Gruenbacher2005-06-22
| | | | | | | | | | | | | | | | | | | | | | | 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.
