The extra call to cache_revisit_request in cache_fresh_unlocked is not needed, as should have been fairly clear at the time of commit 4013edea If there are requests to be revisited, then we can be sure that CACHE_PENDING is set, so the second call is sufficient. So remove the first call. Then remove the 'new' parameter, then remove the return value for cache_fresh_locked which is only used to provide the value for 'new'.

As "cache_defer_req" does not sound like a predicate, having it return a boolean value can be confusing. It is more consistent to return 0 for success and negative for error. Exactly what error code to return is not important as we don't differentiate between reasons why the request wasn't deferred, we only care about whether it was deferred or not.

nfsd4_path() allocates a temporary filehandle and then fails to free it before the function exits, leaking reference counts to the dentry and export that it refers to. Also, nfsd4_lookupp() puts the result of exp_pseudoroot() in a temporary filehandle which it releases on success of exp_pseudoroot() but not on failure; fix exp_pseudoroot to ensure that on failure it releases the filehandle before returning.

Use NFSD_SLOT_CACHE_SIZE size buffers for sessions DRC instead of holding nfsd pages in cache. Connectathon testing has shown that 1024 bytes for encoded compound operation responses past the sequence operation is sufficient, 512 bytes is a little too small. Set NFSD_SLOT_CACHE_SIZE to 1024. Allocate memory for the session DRC in the CREATE_SESSION operation to guarantee that the memory resource is available for caching responses. Allocate each slot individually in preparation for slot table size negotiation. Remove struct nfsd4_cache_entry and helper functions for the old page-based DRC. The iov_len calculation in nfs4svc_encode_compoundres is now always correct. Replay is now done in nfsd4_sequence under the state lock, so the session ref count is only bumped on non-replay. Clean up the nfs4svc_encode_compoundres session logic. The nfsd4_compound_state statp pointer is also not used. Remove nfsd4_set_statp(). Move useful nfsd4_cache_entry fields into nfsd4_slot.

This fixes a bug in the sequence operation reply. The sequence operation returns the highest slotid it will accept in the future in sr_highest_slotid, and the highest slotid it prefers the client to use. Since we do not re-negotiate the session slot table yet, these should both always be set to the session ca_maxrequests. Signed-off-by: NAndy Adamson <andros@netapp.com> Signed-off-by: NJ.

By using the requested ca_maxresponsesize_cached * ca_maxresponses to bound a forechannel drc request size, clients can tailor a session to usage. For example, an I/O session (READ/WRITE only) can have a much smaller ca_maxresponsesize_cached (for only WRITE compound responses) and a lot larger ca_maxresponses to service a large in-flight data window.

Compounds consisting of only a sequence operation don't need any additional caching beyond the sequence information we store in the slot entry. Fix nfsd4_is_solo_sequence to identify this case correctly. The additional check for a failed sequence in nfsd4_store_cache_entry() is redundant, since the nfsd4_is_solo_sequence call lower down catches this case. The final ce_cachethis set in nfsd4_sequence is also redundant. Signed-off-by: NAndy Adamson <andros@netapp.com> Signed-off-by: NJ. Bruce Fields <bfields@citi.umich.edu>

RFC 3530 says "ACE4_IDENTIFIER_GROUP flag MUST be ignored on entries with these special identifiers. When encoding entries with these special identifiers, the ACE4_IDENTIFIER_GROUP flag SHOULD be set to zero." It really shouldn't matter either way, but the point is that this flag is used to distinguish named users from named groups (since unix allows a group to have the same name as a user), so it doesn't really make sense to use it on a special identifier such as this.)

lock_kernel() in knfsd was replaced with a mutex. The later commit 03cf6c9f ("knfsd: add file to export stats about nfsd pools") did not follow that change. This patch fixes the issue.

The group deny entries end up denying tcy even though tcy was just allowed by the allow entry. This appears to be due to: ace->access_mask = mask_from_posix(deny, flags); instead of: ace->access_mask = deny_mask_from_posix(deny, flags); Denying a previously allowed bit has no effect, so this shouldn't affect behavior, but it's ugly.

When a SETCLIENTID call comes in, one of the args given is the svc_rqst. This struct contains an rq_addr field which holds the address that sent the call. If this is an IPv6 address, then we can use the sin6_scope_id field in this address to populate the sin6_scope_id field in the callback address. AFAICT, the rq_addr.sin6_scope_id is non-zero if and only if the client mounted the server's link-local address.
