nfsd4: use xdr_reserve_space in attribute encoding

2014-05-28T18:52:34+00:00

This is a cosmetic change for now; no change in behavior. Note we're just depending on xdr_reserve_space to do the bounds checking for us, we're not really depending on its adjustment of iovec or xdr_buf lengths yet, as those are fixed up by as necessary after the fact by read-link operations and by nfs4svc_encode_compoundres. However we do have to update xdr->iov on read-like operations to prevent xdr_reserve_space from messing with the already-fixed-up length of the the head. When the attribute encoding fails partway through we have to undo the length adjustments made so far. We do it manually for now, but later patches will add an xdr_truncate_encode() helper to handle cases like this. Signed-off-by: J. Bruce Fields

nfsd4: simplify xdr encoding of nfsv4 names

2014-01-08T17:18:53+00:00

We can simplify the idmapping code if it does its own encoding and returns nfs errors. Signed-off-by: J. Bruce Fields

Merge branch 'for-3.9' of git://linux-nfs.org/~bfields/linux

2013-03-01T02:02:55+00:00

Pull nfsd changes from J Bruce Fields: "Miscellaneous bugfixes, plus: - An overhaul of the DRC cache by Jeff Layton. The main effect is just to make it larger. This decreases the chances of intermittent errors especially in the UDP case. But we'll need to watch for any reports of performance regressions. - Containerized nfsd: with some limitations, we now support per-container nfs-service, thanks to extensive work from Stanislav Kinsbursky over the last year." Some notes about conflicts, since there were *two* non-data semantic conflicts here: - idr_remove_all() had been added by a memory leak fix, but has since become deprecated since idr_destroy() does it for us now. - xs_local_connect() had been added by this branch to make AF_LOCAL connections be synchronous, but in the meantime Trond had changed the calling convention in order to avoid a RCU dereference. There were a couple of more obvious actual source-level conflicts due to the hlist traversal changes and one just due to code changes next to each other, but those were trivial. * 'for-3.9' of git://linux-nfs.org/~bfields/linux: (49 commits) SUNRPC: make AF_LOCAL connect synchronous nfsd: fix compiler warning about ambiguous types in nfsd_cache_csum svcrpc: fix rpc server shutdown races svcrpc: make svc_age_temp_xprts enqueue under sv_lock lockd: nlmclnt_reclaim(): avoid stack overflow nfsd: enable NFSv4 state in containers nfsd: disable usermode helper client tracker in container nfsd: use proper net while reading "exports" file nfsd: containerize NFSd filesystem nfsd: fix comments on nfsd_cache_lookup SUNRPC: move cache_detail->cache_request callback call to cache_read() SUNRPC: remove "cache_request" argument in sunrpc_cache_pipe_upcall() function SUNRPC: rework cache upcall logic SUNRPC: introduce cache_detail->cache_request callback NFS: simplify and clean cache library NFS: use SUNRPC cache creation and destruction helper for DNS cache nfsd4: free_stid can be static nfsd: keep a checksum of the first 256 bytes of request sunrpc: trim off trailing checksum before returning decrypted or integrity authenticated buffer sunrpc: fix comment in struct xdr_buf definition ...

SUNRPC: rework cache upcall logic

2013-02-15T15:43:46+00:00

For most of SUNRPC caches (except NFS DNS cache) cache_detail->cache_upcall is redundant since all that it's implementations are doing is calling sunrpc_cache_pipe_upcall() with proper function address argument. Cache request function address is now stored on cache_detail structure and thus all the code can be simplified. Now, for those cache details, which doesn't have cache_upcall callback (the only one, which still has is nfs_dns_resolve_template) sunrpc_cache_pipe_upcall will be called instead.

SUNRPC: introduce cache_detail->cache_request callback

nfsd: Convert idmap to use kuids and kgids

2013-02-13T14:15:49+00:00

Convert nfsd_map_name_to_uid to return a kuid_t value. Convert nfsd_map_name_to_gid to return a kgid_t value. Convert nfsd_map_uid_to_name to take a kuid_t parameter. Convert nfsd_map_gid_to_name to take a kgid_t paramater. Cc: "J. Bruce Fields" Cc: Trond Myklebust Signed-off-by: "Eric W. Biederman"

nfsd: idmap use u32 not uid_t as the intermediate type

2013-02-13T14:15:37+00:00

u32 and uid_t have the same size and semantics so this change should have no operational effect. This just removes the WTF factor when looking at variables that hold both uids and gids whos type is uid_t. Cc: "J. Bruce Fields" Cc: Trond Myklebust Signed-off-by: "Eric W. Biederman"

NFSD: pass null terminated buf to kstrtouint()

The 'buf' is prepared with null termination with intention of using it for this purpose, but 'name' is passed instead! Signed-off-by: Malahal Naineni Cc: stable@vger.kernel.org Signed-off-by: J. Bruce Fields
