2023-10-16NFSD: Add simple u32, u64, and bool encodersChuck Lever1-0/+111
The generic XDR encoders return a length or a negative errno. NFSv4 encoders want to know simply whether the encode ran out of stream buffer space. The return values for server-side encoding are either nfs_ok or nfserr_resource. So far I've found it adds a lot of duplicate code to try to use the generic XDR encoder utilities when encoding the simple data types in the NFSv4 operation encoders. Add a set of NFSv4-specific utilities that handle the basic XDR data types. These are added in xdr4.h so they might eventually be used by the callback server and pNFS driver encoders too.

2023-10-16NFSD: handle GETATTR conflict with write delegationDai Ngo3-14/+121
If the GETATTR request on a file that has write delegation in effect and the request attributes include the change info and size attribute then the request is handled as below: Server sends CB_GETATTR to client to get the latest change info and file size. If these values are the same as the server's cached values then the GETATTR proceeds as normal. If either the change info or file size is different from the server's cached values, or the file was already marked as modified, then: . update time_modify and time_metadata into file's metadata with current time . encode GETATTR as normal except the file size is encoded with the value returned from CB_GETATTR . mark the file as modified If the CB_GETATTR fails for any reasons, the delegation is recalled and NFS4ERR_DELAY is returned for the GETATTR.

2023-10-16SUNRPC: change sp_nrthreads to atomic_tNeilBrown1-6/+5
Using an atomic_t avoids the need to take a spinlock (which can soon be removed). Choosing a thread to kill needs to be careful as we cannot set the "die now" bit atomically with the test on the count. Instead we temporarily increase the count.

2023-10-16SUNRPC: change how svc threads are asked to exit.NeilBrown2-4/+6
svc threads are currently stopped using kthread_stop(). This requires identifying a specific thread. However we don't care which thread stops, just as long as one does. So instead, set a flag in the svc_pool to say that a thread needs to die, and have each thread check this flag instead of calling kthread_should_stop(). The first thread to find and clear this flag then moves towards exiting. This removes an explicit dependency on sp_all_threads which will make a future patch simpler.

2023-10-16lockd: introduce safe async lock opAlexander Aring1-3/+7
This patch reverts mostly commit 40595cdc93ed ("nfs: block notification on fs with its own ->lock") and introduces an EXPORT_OP_ASYNC_LOCK export flag to signal that the "own ->lock" implementation supports async lock requests. The only main user is DLM that is used by GFS2 and OCFS2 filesystem. Those implement their own lock() implementation and return FILE_LOCK_DEFERRED as return value. Since commit 40595cdc93ed ("nfs: block notification on fs with its own ->lock") the DLM implementation were never updated. This patch should prepare for DLM to set the EXPORT_OP_ASYNC_LOCK export flag and update the DLM plock implementation regarding to it.

2023-10-16nfsd: Don't reset the write verifier on a commit EAGAINTrond Myklebust1-10/+23
If fsync() is returning EAGAIN, then we can assume that the filesystem being exported is something like NFS with the 'softerr' mount option enabled, and that it is just asking us to replay the fsync() operation at a later date. If we see an ESTALE, then ditto: the file is gone, so there is no danger of losing the error. For those cases, do not reset the write verifier. A write verifier change has a global effect, causing retransmission by all clients of all uncommitted unstable writes for all files, so it is worth mitigating where possible.
