2020-12-09NFSD: Fix 5 seconds delay when doing inter server copyDai Ngo1-0/+1
Since commit b4868b44c5628 ("NFSv4: Wait for stateid updates after CLOSE/OPEN_DOWNGRADE"), every inter server copy operation suffers 5 seconds delay regardless of the size of the copy. The delay is from nfs_set_open_stateid_locked when the check by nfs_stateid_is_sequential fails because the seqid in both nfs4_state and nfs4_stateid are 0. Fix by modifying nfs4_init_cp_state to return the stateid with seqid 1 instead of 0. This is also to conform with section 4.8 of RFC 7862. Here is the relevant paragraph from section 4.8 of RFC 7862: A copy offload stateid's seqid MUST NOT be zero. In the context of a copy offload operation, it is inappropriate to indicate "the most recent copy offload operation" using a stateid with a seqid of zero (see Section 8.2.2 of [RFC5661]). It is inappropriate because the stateid refers to internal state in the server and there may be several asynchronous COPY operations being performed in parallel on the same file by the server. Therefore, a copy offload stateid with a seqid of zero MUST be considered invalid.

2020-12-09NFSD: Fix sparse warning in nfs4proc.cChuck Lever1-6/+2
linux/fs/nfsd/nfs4proc.c:1542:24: warning: incorrect type in assignment (different base types) linux/fs/nfsd/nfs4proc.c:1542:24: expected restricted __be32 [assigned] [usertype] status linux/fs/nfsd/nfs4proc.c:1542:24: got int Clean-up: The dup_copy_fields() function returns only zero, so make it return void for now, and get rid of the return code check.

2020-12-09SUNRPC: Remove XDRBUF_SPARSE_PAGES flag in gss_proxy upcallChuck Lever2-6/+10
There's no need to defer allocation of pages for the receive buffer. - This upcall is quite infrequent - gssp_alloc_receive_pages() can allocate the pages with GFP_KERNEL, unlike the transport - gssp_alloc_receive_pages() knows exactly how many pages are needed Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Reviewed-by: Olga Kornievskaia <kolga@netapp.com>
2020-12-09sunrpc: clean-up cache downcallRoberto Bergantinos Corpas1-30/+11
We can simplify code around cache_downcall unifying memory allocations using kvmalloc. This has the benefit of getting rid of cache_slow_downcall (and queue_io_mutex), and also matches userland allocation size and limits.

The warning message from nfsd terminating normally can confuse system adminstrators or monitoring software.

2020-11-30NFSD: Remove macros that are no longer usedChuck Lever2-49/+0
Now that all the NFSv4 decoder functions have been converted to make direct calls to the xdr helpers, remove the unused C macros. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
2020-11-30NFSD: Replace READ* macros in nfsd4_decode_compound()Chuck Lever1-40/+29
And clean-up: Now that we have removed the DECODE_TAIL macro from nfsd4_decode_compound(), we observe that there's no benefit for nfsd4_decode_compound() to return nfs_ok or nfserr_bad_xdr only to have its sole caller convert those values to one or zero, respectively. Have nfsd4_decode_compound() return 1/0 instead. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>
