Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2021-01-25NFSD: Update the NFSv2 ACL ACCESS argument decoder to use struct xdr_streamChuck Lever
Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2021-01-25NFSD: Update the NFSv2 ACL GETATTR argument decoder to use struct xdr_streamChuck Lever
Since the ACL GETATTR procedure is the same as the normal GETATTR procedure, simply re-use nfssvc_decode_fhandleargs. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>

Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2021-01-25NFSD: Update the NFSv2 GETACL argument decoder to use struct xdr_streamChuck Lever
Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2021-01-25NFSD: Remove argument length checking in nfsd_dispatch()Chuck Lever
Now that the argument decoders for NFSv2 and NFSv3 use the xdr_stream mechanism, the version-specific length checking logic in nfsd_dispatch() is no longer necessary. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2021-01-25NFSD: Update the NFSv2 SYMLINK argument decoder to use struct xdr_streamChuck Lever
Signed-off-by: Chuck Lever <chuck.lever@oracle.com>

Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2021-01-25NFSD: Update the NFSv2 READDIR argument decoder to use struct xdr_streamChuck Lever
As an additional clean up, move code not related to XDR decoding into readdir's .pc_func call out. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2021-01-25NFSD: Add helper to set up the pages where the dirlist is encodedChuck Lever
Add a helper similar to nfsd3_init_dirlist_pages(). Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2021-01-25NFSD: Update the NFSv2 READLINK argument decoder to use struct xdr_streamChuck Lever
If the code that sets up the sink buffer for nfsd_readlink() is moved adjacent to the nfsd_readlink() call site that uses it, then the only argument is a file handle, and the fhandle decoder can be used instead. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2021-01-25NFSD: Update the NFSv2 WRITE argument decoder to use struct xdr_streamChuck Lever
Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2021-01-25NFSD: Update the NFSv2 READ argument decoder to use struct xdr_streamChuck Lever
The code that sets up rq_vec is refactored so that it is now adjacent to the nfsd_read() call site where it is used. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2021-01-25NFSD: Update the NFSv2 GETATTR argument decoder to use struct xdr_streamChuck Lever
Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2021-01-25NFSD: Update the MKNOD3args decoder to use struct xdr_streamChuck Lever
This commit removes the last usage of the original decode_sattr3(), so it is removed as a clean-up. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2021-01-25NFSD: Update the SYMLINK3args decoder to use struct xdr_streamChuck Lever
Similar to the WRITE decoder, code that checks the sanity of the payload size is re-wired to work with xdr_stream infrastructure. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2021-01-25NFSD: Update the MKDIR3args decoder to use struct xdr_streamChuck Lever
Signed-off-by: Chuck Lever <chuck.lever@oracle.com>

2021-01-25NFSD: Update the NFSv3 DIROPargs decoder to use struct xdr_streamChuck Lever
Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2021-01-25NFSD: Update COMMIT3arg decoder to use struct xdr_streamChuck Lever
Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2021-01-25NFSD: Update READDIR3args decoders to use struct xdr_streamChuck Lever
As an additional clean up, neither nfsd3_proc_readdir() nor nfsd3_proc_readdirplus() make use of the dircount argument, so remove it from struct nfsd3_readdirargs. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2021-01-25NFSD: Add helper to set up the pages where the dirlist is encodedChuck Lever
De-duplicate some code that is used by both READDIR and READDIRPLUS to build the dirlist in the Reply. Because this code is not related to decoding READ arguments, it is moved to a more appropriate spot. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2021-01-25NFSD: Fix returned READDIR offset cookieChuck Lever
Code inspection shows that the server's NFSv3 READDIR implementation handles offset cookies slightly differently than the NFSv2 READDIR, NFSv3 READDIRPLUS, and NFSv4 READDIR implementations, and there doesn't seem to be any need for this difference. As a clean up, I copied the logic from nfsd3_proc_readdirplus(). Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2021-01-25NFSD: Update READLINK3arg decoder to use struct xdr_streamChuck Lever
The NFSv3 READLINK request takes a single filehandle, so it can re-use GETATTR's decoder. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2021-01-25NFSD: Update WRITE3arg decoder to use struct xdr_streamChuck Lever
As part of the update, open code that sanity-checks the size of the data payload against the length of the RPC Call message has to be re-implemented to use xdr_stream infrastructure. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2021-01-25NFSD: Update READ3arg decoder to use struct xdr_streamChuck Lever
The code that sets up rq_vec is refactored so that it is now adjacent to the nfsd_read() call site where it is used. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>

2021-01-25NFSD: Update GETATTR3args decoder to use struct xdr_streamChuck Lever
Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2021-01-25SUNRPC: Move definition of XDR_UNITChuck Lever
Clean up: The unit of XDR alignment is defined by RFC 4506, not as part of the RPC message header. Thus it belongs in include/linux/sunrpc/xdr.h. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2021-01-25SUNRPC: Display RPC procedure names instead of proc numbersChuck Lever
Make the sunrpc trace subsystem trace events easier to use. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2021-01-25SUNRPC: Make trace_svc_process() display the RPC procedure symbolicallyChuck Lever
The next few patches will employ these strings to help make server- side trace logs more human-readable. A similar technique is already in use in kernel RPC client code. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
