* nfsd: make NFSd service boot time per-netStanislav Kinsbursky2012-12-101-5/+0
| | | | | | | | | This is simple: an NFSd service can be started at different times in different network environments. So, its "boot time" has to be assigned per net. Signed-off-by: Stanislav Kinsbursky <skinsbursky@parallels.com> Signed-off-by: J. Bruce Fields <bfields@redhat.com>
* nfsd: pass net to nfsd_set_nrthreads()Stanislav Kinsbursky2012-12-101-1/+1
| | | | | | | | Precursor patch. Hard-coded "init_net" will be replaced by proper one in future. Signed-off-by: Stanislav Kinsbursky <skinsbursky@parallels.com> Signed-off-by: J. Bruce Fields <bfields@redhat.com>

* nfsd: make NFSv4 grace time per netStanislav Kinsbursky2012-11-281-2/+0
| | | | | | | | Grace time is a part of NFSv4 state engine, which is constructed per network namespace. Signed-off-by: Stanislav Kinsbursky <skinsbursky@parallels.com> Signed-off-by: J. Bruce Fields <bfields@redhat.com>
* nfsd: make NFSv4 lease time per netStanislav Kinsbursky2012-11-281-1/+0

* nfsd: call state init and shutdown twiceStanislav Kinsbursky2012-11-281-0/+4
| | | | | | | | | | | Split NFSv4 state init and shutdown into two different calls: per-net one and generic one. Per-net cwinit/shutdown pair have to be called for any namespace, generic pair - only once on NSFd kthreads start and shutdown respectively.

* nfsd: remove redundant "port" argumentJ. Bruce Fields2012-08-211-1/+1
| | | | | | | | | "port" in all these functions is always NFS_PORT. nfsd can already be run on a nonstandard port using the "nfsd/portlist" interface. Signed-off-by: J. Bruce Fields <bfields@redhat.com>

* NFSd: set nfsd_serv to NULL after service destructionStanislav Kinsbursky2012-07-251-0/+2
| | | | | | | | | | | | | | In nfsd_destroy(): if (destroy) svc_shutdown_net(nfsd_serv, net); svc_destroy(nfsd_server); svc_shutdown_net(nfsd_serv, net) calls nfsd_last_thread(), which sets nfsd_serv to NULL, causing a NULL dereference on the following line.

* nfsd: only register cld pipe notifier when CONFIG_NFSD_V4 is enabledJeff Layton2012-03-291-1/+6
| | | | | | | | | | | | | | | 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.

* NFSD: Call nfsd4_init_slabs() from init_nfsd()Bryan Schumaker2011-11-071-2/+4
| | | | | | | | | 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.

* nfsd4: name->id mapping should fail with BADOWNER not BADNAMEJ. Bruce Fields2011-01-041-0/+1
| | | | | | | | | | | | | 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.

* nfsd4: expire clients more promptlyJ. Bruce Fields2010-10-111-1/+1
| | | | | | | | | | | 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.

* nfsd4: share file descriptors between stateid'sJ. Bruce Fields2010-07-291-0/+1
| | | | | | | | | | | | | | | | 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.

* nfsd4: simplify references to nfsd4 lease timeJ. Bruce Fields2010-03-061-3/+2
| | | | | | | | 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>
* nfsd: remove pointless paths in file headersJ. Bruce Fields2009-12-151-2/+0
| | | | | | | | 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>
* nfsd: restrict filehandles accepted in V4ROOT caseSteve Dickson2009-12-151-0/+5
| | | | | | | | | | | | | 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.
