| * | lockd: create and use per-net NSM RPC clients on MON/UNMON requestsStanislav Kinsbursky2012-10-021-17/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | NSM RPC client can be required on NFSv3 umount, when child reaper is dying (and destroying it's mount namespace). It means, that current nsproxy is set to NULL already, but creation of RPC client requires UTS namespace for gaining hostname string. This patch creates reference-counted per-net NSM client on first monitor request and destroys it after last unmonitor request.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This new routine is responsible for service registration in a specified network context. The idea is to separate service creation from per-net operations. Note also: since registering service with svc_bind() can fail, the service will be destroyed and during destruction it will try to unregister itself from rpcbind. In this case unregistration has to be skipped. Signed-off-by: Stanislav Kinsbursky <skinsbursky@parallels.com> Signed-off-by: J. Bruce Fields <bfields@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces per-net Lockd initialization and destruction routines. The logic is the same as in global Lockd up and down routines. Probably the solution is not the best one. But at least it looks clear. So per-net "up" routine are called only in case of lockd is running already. If per-net resources are not allocated yet, then service is being registered with local portmapper and lockd sockets created. Per-net "down" routine is called on every lockd_down() call in case of global users counter is not zero.

It also replaces hard-coded init_net with current network namespace context in Lockd sockets creation routines. This approach looks safe, because Lockd is created during NFS mount (or NFS server start) and thus socket is required exactly in current network namespace context. But in the same time it means, that Lockd sockets inherits first Lockd requester network namespace. This issue will be fixed in further patches of the series.

* | locks: rename lock-manager opsJ. Bruce Fields2011-07-211-4/+4
|/ | | | | | | | | | | Both the filesystem and the lock manager can associate operations with a lock. Confusingly, one of them (fl_release_private) actually has the same name in both operation structures. It would save some confusion to give the lock-manager ops different names. Signed-off-by: J.

* NLM: Don't hang forever on NLM unlock requestsTrond Myklebust2011-06-151-1/+7
| | | | | | | | | | | If the NLM daemon is killed on the NFS server, we can currently end up hanging forever on an 'unlock' request, instead of aborting. Basically, if the rpcbind request fails, or the server keeps returning garbage, we really want to quit instead of retrying.
