* NFS: create completion structure to pass into page_init functionsFred Isaman2012-04-27

* NFS: merge _full and _partial write rpc_opsFred Isaman2012-04-27
| | | | | | | | | | | | | | | | | Decouple nfs_pgio_header and nfs_write_data, and have (possibly multiple) nfs_write_datas each take a refcount on nfs_pgio_header. For the moment keeps nfs_write_header as a way to preallocate a single nfs_write_data with the nfs_pgio_header. The code doesn't need this, and would be prettier without, but given the amount of churn I am already introducing I didn't want to play with tuning new mempools. This also fixes bug in pnfs_ld_handle_write_error. In the case of desc->pg_bsize < PAGE_CACHE_SIZE, the pages list was empty, causing replay attempt to do nothing.

* NFS: create common nfs_pgio_header for both read and writeFred Isaman2012-04-27
| | | | | | | | | | | | | | | | | In order to avoid duplicating all the data in nfs_read_data whenever we split it up into multiple RPC calls (either due to a short read result or due to rsize < PAGE_SIZE), we split out the bits that are the same per RPC call into a separate "header" structure. The goal this patch moves towards is to have a single header refcounted by several rpc_data structures. Thus, want to always refer from rpc_data to the header, and not the other way. This patch comes close to that ideal, but the directio code currently needs some special casing, isolated in the nfs_direct_[read_write]hdr_release() functions. This will be dealt with in a future patch. Signed-off-by: Fred Isaman <iisaman@netapp.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

* NFSv4: Ensure we do not reuse open owner namesTrond Myklebust2012-04-20
| | | | | | | | | | The NFSv4 spec is ambiguous about whether or not it is permissible to reuse open owner names, so play it safe. This patch adds a timestamp to the state_owner structure, and combines that with the IDA based uniquifier. Fixes a regression whereby the Linux server returns NFS4ERR_BAD_SEQID.

| * NFSv4: Fix an Oops in the NFSv4 getacl codeTrond Myklebust2012-02-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit bf118a342f10dafe44b14451a1392c3254629a1f (NFSv4: include bitmap in nfsv4 get acl data) introduces the 'acl_scratch' page for the case where we may need to decode multi-page data. However it fails to take into account the fact that the variable may be NULL (for the case where we're not doing multi-page decode), and it also attaches it to the encoding xdr_stream rather than the decoding one. The immediate result is an Oops in nfs4_xdr_enc_getacl due to the call to page_address() with a NULL page pointer.

* | NFS: Request fh_expire_type attribute in "server caps" operationChuck Lever2012-03-02
| | | | | | | | | | | | | | | | | | | | | | | | | | The fh_expire_type file attribute is a filesystem wide attribute that consists of flags that indicate what characteristics file handles on this FSID have. Our client doesn't support volatile file handles. It should find out early (say, at mount time) whether the server is going to play shenanighans with file handles during a migration.

* | NFS: Introduce NFS_ATTR_FATTR_V4_LOCATIONSChuck Lever2012-03-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Linux NFS client must distinguish between referral events (which it currently supports) and migration events (which it does not yet support). In both types of events, an fs_locations array is returned. But upper layers, not the XDR layer, should make the distinction between a referral and a migration. There really isn't a way for an XDR decoder function to distinguish the two, in general. Slightly adjust the FATTR flags returned by decode_fs_locations() to set NFS_ATTR_FATTR_V4_LOCATIONS only if a non-empty locations array was returned from the server. Then have logic in nfs4proc.c distinguish whether the locations array is for a referral or something else.

* NFSv4: Save the owner/group name string when doing openTrond Myklebust2012-01-07
| | | | | | | | | | | | | | | ...so that we can do the uid/gid mapping outside the asynchronous RPC context. This fixes a bug in the current NFSv4 atomic open code where the client isn't able to determine what the true uid/gid fields of the file are, (because the asynchronous nature of the OPEN call denies it the ability to do an upcall) and so fills them with default values, marking the inode as needing revalidation. Unfortunately, in some cases, the VFS will do some additional sanity checks on the file, and may override the server's decision to allow the open because it sees the wrong owner/group fields.

* NFSv4: include bitmap in nfsv4 get acl dataAndy Adamson2012-01-05
| | | | | | | | | | | | | | | | | | | The NFSv4 bitmap size is unbounded: a server can return an arbitrary sized bitmap in an FATTR4_WORD0_ACL request. Replace using the nfs4_fattr_bitmap_maxsz as a guess to the maximum bitmask returned by a server with the inclusion of the bitmap (xdr length plus bitmasks) and the acl data xdr length to the (cached) acl page data. This is a general solution to commit e5012d1f "NFSv4.1: update nfs4_fattr_bitmap_maxsz" and fixes hitting a BUG_ON in xdr_shrink_bufhead when getting ACLs. Fix a bug in decode_getacl that returned -EINVAL on ACLs > page when getxattr was called with a NULL buffer, preventing ACL > PAGE_SIZE from being retrieved.

* nfs: when attempting to open a directory, fall back on normal lookup (try #5)Jeff Layton2011-11-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | commit d953126 changed how nfs_atomic_lookup handles an -EISDIR return from an OPEN call. Prior to that patch, that caused the client to fall back to doing a normal lookup. When that patch went in, the code began returning that error to userspace. The d_revalidate codepath however never had the corresponding change, so it was still possible to end up with a NULL ctx->state pointer after that. That patch caused a regression. When we attempt to open a directory that does not have a cached dentry, that open now errors out with EISDIR. If you attempt the same open with a cached dentry, it will succeed. Fix this by reverting the change in nfs_atomic_lookup and allowing attempts to open directories to fall back to a normal lookup Also, add a NFSv4-specific f_ops->open routine that just returns -ENOTDIR. This should never be called if things are working properly, but if it ever is, then the dprintk may help in debugging. To facilitate this, a new file_operations field is also added to the nfs_rpc_ops struct.
