NFS: Pass error information to the pgio error cleanup routine

2019-02-20T20:14:20+00:00

Allow the caller to pass error information when cleaning up a failed I/O request so that we can conditionally take action to cancel the request altogether if the error turned out to be fatal. Signed-off-by: Trond Myklebust

NFS/NFSD/SUNRPC: replace generic creds with 'struct cred'.

2018-12-19T18:52:46+00:00

SUNRPC has two sorts of credentials, both of which appear as "struct rpc_cred". There are "generic credentials" which are supplied by clients such as NFS and passed in 'struct rpc_message' to indicate which user should be used to authorize the request, and there are low-level credentials such as AUTH_NULL, AUTH_UNIX, AUTH_GSS which describe the credential to be sent over the wires. This patch replaces all the generic credentials by 'struct cred' pointers - the credential structure used throughout Linux. For machine credentials, there is a special 'struct cred *' pointer which is statically allocated and recognized where needed as having a special meaning. A look-up of a low-level cred will map this to a machine credential. Signed-off-by: NeilBrown Acked-by: J. Bruce Fields Signed-off-by: Anna Schumaker

NFS: struct nfs_open_dir_context: convert rpc_cred pointer to cred.

Use the common 'struct cred' to pass credentials for readdir. Signed-off-by: NeilBrown Signed-off-by: Anna Schumaker

NFS: Remove private spinlock in struct nfs_pgio_header

2018-09-30T19:35:17+00:00

Now that each struct nfs_pgio_header corresponds to one RPC call, we only have one writer to the struct nfs_pgio_header. Signed-off-by: Trond Myklebust

NFSv4: Save a few bytes in the nfs_pgio_args/res

2018-09-30T19:35:17+00:00

Save a few bytes by allowing the read/write specific fields of the structures to share storage. Signed-off-by: Trond Myklebust

NFSv3: Improve NFSv3 performance when server returns no post-op attributes

2018-09-30T19:35:17+00:00

When the server fails to return post-op attributes, the client's attempt to place read data directly in the page cache fails, and so we have to do an extra copy in order to realign the data with page borders. This patch attempts to detect servers that don't return post-op attributes on read (e.g. for pNFS) and adjusts the placement calculation accordingly. Signed-off-by: Trond Myklebust

NFS add support for asynchronous COPY

2018-08-09T16:56:39+00:00

Change xdr to always send COPY asynchronously. Keep the list copies send in a list under a server structure. Once copy is sent, it waits on a completion structure that will be signalled by the callback thread that receives CB_OFFLOAD. If CB_OFFLOAD returned an error and even if it returned partial bytes, ignore them (as we can't commit without a verifier to match) and return an error.

NFS COPY xdr handle async reply

If server returns async reply, it must include a callback stateid, wr_callback_id in the write_response4. Signed-off-by: Olga Kornievskaia Signed-off-by: Anna Schumaker
