nfsd: be more systematic about selecting error codes for internal use.

2024-09-20T23:31:03+00:00

Rather than using ad hoc values for internal errors (30000, 11000, ...) use 'enum' to sequentially allocate numbers starting from the first known available number - now visible as NFS4ERR_FIRST_FREE. The goal is values that are distinct from all be32 error codes. To get those we must first select integers that are not already used, then convert them with cpu_to_be32().

NFSv4: Add support for the FATTR4_OPEN_ARGUMENTS attribute

2024-07-08T17:47:25+00:00

Query the server for the OPEN arguments that it supports so that we can figure out which extensions we can use. Signed-off-by: Trond Myklebust Signed-off-by: Lance Shelton Reviewed-by: Jeff Layton Signed-off-by: Trond Myklebust Signed-off-by: Anna Schumaker

nfsd: trivial GET_DIR_DELEGATION support

2024-05-06T13:07:17+00:00

This adds basic infrastructure for handing GET_DIR_DELEGATION calls from clients, including the decoders and encoders. For now, it always just returns NFS4_OK + GDD4_UNAVAIL. Eventually clients may start sending this operation, and it's better if we can return GDD4_UNAVAIL instead of having to abort the whole compound.

NFSD: Copy FATTR4 bit number definitions from RFCs

2023-10-16T16:44:26+00:00

I'd like to convert nfsd4_encode_fattr() to rotate through the attrmask using for_each_bit() instead of explicitly testing the bitmask for each bit value. This means I need the bit numbers, as defined in the specs, instead of our internal bitmask constants. As a clean up, use the new spec-derived values to define the WORD# bitmask constants.

NFSD: add delegation reaper to react to low memory condition

2022-12-10T16:01:12+00:00

The delegation reaper is called by nfsd memory shrinker's on the 'count' callback. It scans the client list and sends the courtesy CB_RECALL_ANY to the clients that hold delegations. To avoid flooding the clients with CB_RECALL_ANY requests, the delegation reaper sends only one CB_RECALL_ANY request to each client per 5 seconds.

NFS: Move NFS protocol display macros to global header

Refactor: surface useful show_ macros so they can be shared between the client and server trace code. Additional clean up: - Housekeeping: ensure the correct #include files are pulled in and add proper TRACE_DEFINE_ENUM where they are missing - Use a consistent naming scheme for the helpers - Store values to be displayed symbolically as unsigned long, as that is the type that the __print_yada() functions take Signed-off-by: Chuck Lever Signed-off-by: Trond Myklebust
