lockd: eliminate LOCKD_DEBUG

2014-11-24T22:24:08Z

LOCKD_DEBUG is always the same value as CONFIG_SUNRPC_DEBUG, so we can just use it instead. Signed-off-by: Jeff Layton Signed-off-by: Trond Myklebust

lockd: rip out deferred lock handling from testlock codepath

2014-09-09T20:01:09Z

As Kinglong points out, the nlm_block->b_fl field is no longer used at all. Also, vfs_test_lock in the generic locking code will only return FILE_LOCK_DEFERRED if FL_SLEEP is set, and it isn't here. The only other place that returns that value is the DLM lock code, but it only does that in dlm_posix_lock, never in dlm_posix_get. Remove all of the deferred locking code from the testlock codepath since it doesn't appear to ever be used anyway. I do have a small concern that this might cause a behavior change in the case where you have a block already sitting on the list when the testlock request comes in, but that looks like it doesn't really work properly anyway. I think it's best to just pass that down to vfs_test_lock and let the filesystem report that instead of trying to infer what's going on with the lock by looking at an existing block.

nfsd: remove

2014-05-06T21:54:53Z

The only real user of this header is fs/nfsd/nfsfh.h, so merge the two. Various lockѕ source files used it to indirectly get other sunrpc or nfs headers, so fix those up. Signed-off-by: Christoph Hellwig Signed-off-by: J. Bruce Fields

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

2013-03-01T02:02:55Z

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 ...

lockd: nlmclnt_reclaim(): avoid stack overflow

2013-02-15T16:29:38Z

Even though nlmclnt_reclaim() is only one call into the stack frame, 928 bytes on the stack seems like a lot. Recode to dynamically allocate the request structure once from within the reclaimer task, then pass this pointer into nlmclnt_reclaim() for reuse on subsequent calls. smatch analysis: fs/lockd/clntproc.c:620 nlmclnt_reclaim() warn: 'reqst' puts 928 bytes on stack Also remove redundant assignment of 0 after memset.

LockD: pass actual network namespace to grace period management functions

LockD: mark host per network namespace on garbage collect

This is required for per-network NLM shutdown and cleanup. This patch passes init_net for a while. Signed-off-by: Stanislav Kinsbursky Signed-off-by: J. Bruce Fields

Lockd: pass network namespace to creation and destruction routines

2012-04-11T21:55:06Z

v2: dereference of most probably already released nlm_host removed in nlmclnt_done() and reclaimer(). These routines are called from locks reclaimer() kernel thread. This thread works in "init_net" network context and currently relays on persence on lockd thread and it's per-net resources. Thus lockd_up() and lockd_down() can't relay on current network context. So let's pass corrent one into them. Signed-off-by: Stanislav Kinsbursky Signed-off-by: J. Bruce Fields
