2012-03-29nfsd: only register cld pipe notifier when CONFIG_NFSD_V4 is enabledJeff Layton
Otherwise, we get a warning or error similar to this when building with CONFIG_NFSD_V4 disabled: ERROR: "nfsd4_cld_block" [fs/nfsd/nfsd.ko] undefined! Fix this by wrapping the calls to rpc_pipefs_notifier_register and ..._unregister in another function and providing no-op replacements when CONFIG_NFSD_V4 is disabled.

2011-11-08NFSD: Call nfsd4_init_slabs() from init_nfsd()Bryan Schumaker
init_nfsd() was calling free_slabs() during cleanup code, but the call to init_slabs() was hidden in nfsd4_state_init(). This could be confusing to people unfamiliar with the code. Signed-off-by: Bryan Schumaker <bjschuma@netapp.com> Signed-off-by: J. Bruce Fields <bfields@redhat.com>

2011-08-26Remove include/linux/nfsd/const.hJ. Bruce Fields
Userspace shouldn't have a use for these constants. Nothing here is used outside fs/nfsd. Signed-off-by: J. Bruce Fields <bfields@redhat.com>
2011-01-04nfsd4: name->id mapping should fail with BADOWNER not BADNAMEJ. Bruce Fields
According to rfc 3530 BADNAME is for strings that represent paths; BADOWNER is for user/group names that don't map. And the too-long name should probably be BADOWNER as well; it's effectively the same as if we couldn't map it.

2010-10-12nfsd4: expire clients more promptlyJ. Bruce Fields
Expire clients more promptly, at the expense of possibly running the laundromat thread more frequently. Though it's not the default, I'd like it to be feasible to run with a lease time of just a few seconds, at which point a minimum 10 second wait between laundromat runs seems a little much.

2010-07-29nfsd4: share file descriptors between stateid'sJ. Bruce Fields
The vfs doesn't really allow us to "upgrade" a file descriptor from read-only to read-write, and our attempt to do so in nfs4_upgrade_open is ugly and incomplete. Move to a different scheme where we keep multiple opens, shared between open stateid's, in the nfs4_file struct. Each file will be opened at most 3 times (for read, write, and read-write), and those opens will be shared between all clients and openers. On upgrade we will do another open if necessary instead of attempting to upgrade an existing open. We keep count of the number of readers and writers so we know when to close the shared files.

2010-03-06nfsd4: allow setting grace period timeJ. Bruce Fields
Allow explicit configuration of the grace period time as well as the lease period time. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>
2010-03-06nfsd4: simplify references to nfsd4 lease timeJ. Bruce Fields
Instead of accessing the lease time directly, some users call nfs4_lease_time(), and some a macro, NFSD_LEASE_TIME, defined as nfs4_lease_time(). Neither layer of indirection serves any purpose. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>
2009-12-15nfsd: remove pointless paths in file headersJ. Bruce Fields
The new .h files have paths at the top that are now out of date. While we're here, just remove all of those from fs/nfsd; they never served any purpose. Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>
2009-12-15nfsd: restrict filehandles accepted in V4ROOT caseSteve Dickson
On V4ROOT exports, only accept filehandles that are the *root* of some export. This allows mountd to allow or deny access to individual directories and symlinks on the pseudofilesystem. Note that the checks in readdir and lookup are not enough, since a malicious host with access to the network could guess filehandles that they weren't able to obtain through lookup or readdir.
