nfs: add minor version to nfs_server_key for fscache

2020-02-25T18:53:24Z

An NFS client that mounts multiple exports from the same NFS server with higher NFSv4 versions disabled (i.e. 4.2) and without forcing a specific NFS version results in fscache index cookie collisions and the following messages: [ 570.004348] FS-Cache: Duplicate cookie detected Each nfs_client structure should have its own fscache index cookie, so add the minorversion to nfs_server_key.

NFS: Additional refactoring for fs_context conversion

2020-01-15T15:15:17Z

Split out from commit "NFS: Add fs_context support." This patch adds additional refactoring for the conversion of NFS to use fs_context, namely: (*) Merge nfs_mount_info and nfs_clone_mount into nfs_fs_context. nfs_clone_mount has had several fields removed, and nfs_mount_info has been removed altogether. (*) Various functions now take an fs_context as an argument instead of nfs_mount_info, nfs_fs_context, etc. Signed-off-by: Scott Mayhew Signed-off-by: Anna Schumaker

NFS: rename nfs_fs_context pointer arg in a few functions

2020-01-15T15:15:17Z

Split out from commit "NFS: Add fs_context support." Rename cfg to ctx in nfs_init_server(), nfs_verify_authflavors(), and nfs_request_mount(). No functional changes. Signed-off-by: Scott Mayhew Signed-off-by: Anna Schumaker

NFS: Rename struct nfs_parsed_mount_data to struct nfs_fs_context

2020-01-15T15:15:17Z

Rename struct nfs_parsed_mount_data to struct nfs_fs_context and rename pointers to it to "ctx". At some point this will be pointed to by an fs_context struct's fs_private pointer. Signed-off-by: David Howells Signed-off-by: Al Viro Signed-off-by: Anna Schumaker

NFSv4.1: Don't rebind to the same source port when reconnecting to the server

2019-11-04T02:28:45Z

NFSv2, v3 and NFSv4 servers often have duplicate replay caches that look at the source port when deciding whether or not an RPC call is a replay of a previous call. This requires clients to perform strange TCP gymnastics in order to ensure that when they reconnect to the server, they bind to the same source port. NFSv4.1 and NFSv4.2 have sessions that provide proper replay semantics, that do not look at the source port of the connection. This patch therefore ensures they can ignore the rebind requirement.

NFS/pnfs: Separate NFSv3 DS and MDS traffic

2019-11-04T02:28:45Z

If a NFSv3 server is being used as both a DS and as a regular NFSv3 server, we may want to keep the IO traffic on a separate TCP connection, since it will typically have very different timeout characteristics. This patch therefore sets up a flag to separate the two modes of operation for the nfs_client. Signed-off-by: Trond Myklebust

NFS: Cleanup if nfs_match_client is interrupted

Don't bail out before cleaning up a new allocation if the wait for searching for a matching nfs client is interrupted. Memory leaks.
