NFS: Store the credential of the mount process in the nfs_server

2019-04-26T20:11:54+00:00

Store the credential of the mount process so that we can determine information such as the user namespace. Signed-off-by: Trond Myklebust Signed-off-by: Anna Schumaker

NFS: Add a mount option "softerr" to allow clients to see ETIMEDOUT errors

2019-04-25T18:18:14+00:00

Add a mount option that exposes the ETIMEDOUT errors that occur during soft timeouts to the application. This allows aware applications to distinguish between server disk IO errors and client timeout errors. Signed-off-by: Trond Myklebust Signed-off-by: Anna Schumaker

NFS: Move internal constants out of uapi/linux/nfs_mount.h

2019-04-25T18:18:14+00:00

When the label says "for internal use only", then it doesn't belong in the 'uapi' subtree. Signed-off-by: Trond Myklebust Signed-off-by: Anna Schumaker

NFS/SUNRPC: don't lookup machine credential until rpcauth_bindcred().

2018-12-19T18:52:45+00:00

When NFS creates a machine credential, it is a "generic" credential, not tied to any auth protocol, and is really just a container for the princpal name. This doesn't get linked to a genuine credential until rpcauth_bindcred() is called. The lookup always succeeds, so various places that test if the machine credential is NULL, are pointless. As a step towards getting rid of generic credentials, this patch gets rid of generic machine credentials. The nfs_client and rpc_client just hold a pointer to a constant principal name. When a machine credential is wanted, a special static 'struct rpc_cred' pointer is used. rpcauth_bindcred() recognizes this, finds the principal from the client, and binds the correct credential.

NFSv4: add cl_root_cred for use when machine cred is not available.

2018-12-19T18:52:45+00:00

NFSv4 state management tries a root credential when no machine credential is available, as can happen with kerberos. It does this by replacing the cl_machine_cred with a root credential. This means that any user of the machine credential needs to take a lock while getting a reference to the machine credential, which is a little cumbersome. So introduce an explicit cl_root_cred, and never free either credential until client shutdown. This means that no locking is needed to reference these credentials. Future patches will make use of this. This is only a temporary addition. both cl_machine_cred and cl_root_cred will disappear later in the series.

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 handle COPY reply CB_OFFLOAD call race

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

It's possible that server replies back with CB_OFFLOAD call and COPY reply at the same time such that client will process CB_OFFLOAD before reply to COPY. For that keep a list of pending callback stateids received and then before waiting on completion check the pending list. Cleanup any pending copies on the client shutdown.

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.
