(This PR is probably related to kern/84953)

Hi!

I'm having a problem with rpc.lockd

Clients are mainly FreeBSD 5.4-stable, server is FreeBSD-4.11-RELEASE-p13.

/home is nfs mounted via amd.

rpc.statd and rpc.lockd is on for both clients and server

Since we started using eclipse (which requires file locking to
operate) we get problems where the number of open priviledged UDP
ports on the server are exhausted.

running sockstat | grep rpc.lock show over 400 lines like this:

root     rpc.lock   174  440 udp4   *:580                 *:*

The default setting for FreeBSD-4.11 seems to be a portrange of 400
ports, I've bumped this by lowering net.inet.ip.portrange.lowlast from
600 -> 500, but eventually they will all be in use too. I have not
found good way to free them properly apart from rebooting the server.

All nfs traffic is UDP only, perhaps that is a problem?

nfsiod -n 4 on all clients

nfs_server_flags="-u -n 12" on the server, perhaps it is too low?

There are only six workstations attached to the server. Each have
about ten rpc.lockd sockets open, while the server has about 400, so
it seems to be a leakage in the server?

See also kern/84953.

   Log:
   Add the new kernel-mode NFS Lock Manager. To use it instead of the
   user-mode lock manager, build a kernel with the NFSLOCKD option and
   add '-k' to 'rpc_lockd_flags' in rc.conf.
   
   Highlights include:
   
   * Thread-safe kernel RPC client - many threads can use the same RPC
     client handle safely with replies being de-multiplexed at the socket
     upcall (typically driven directly by the NIC interrupt) and handed
     off to whichever thread matches the reply. For UDP sockets, many RPC
     clients can share the same socket. This allows the use of a single
     privileged UDP port number to talk to an arbitrary number of remote
     hosts.
   
   * Single-threaded kernel RPC server. Adding support for multi-threaded
     server would be relatively straightforward and would follow
     approximately the Solaris KPI. A single thread should be sufficient
     for the NLM since it should rarely block in normal operation.
   
   * Kernel mode NLM server supporting cancel requests and granted
     callbacks. I've tested the NLM server reasonably extensively - it
     passes both my own tests and the NFS Connectathon locking tests
     running on Solaris, Mac OS X and Ubuntu Linux.
   
   * Userland NLM client supported. While the NLM server doesn't have
     support for the local NFS client's locking needs, it does have to
     field async replies and granted callbacks from remote NLMs that the
     local client has contacted. We relay these replies to the userland
     rpc.lockd over a local domain RPC socket.
   
   * Robust deadlock detection for the local lock manager. In particular
     it will detect deadlocks caused by a lock request that covers more
     than one blocking request. As required by the NLM protocol, all
     deadlock detection happens synchronously - a user is guaranteed that
     if a lock request isn't rejected immediately, the lock will
     eventually be granted. The old system allowed for a 'deferred
     deadlock' condition where a blocked lock request could wake up and
     find that some other deadlock-causing lock owner had beaten them to
     the lock.
   
   * Since both local and remote locks are managed by the same kernel
     locking code, local and remote processes can safely use file locks
     for mutual exclusion. Local processes have no fairness advantage
     compared to remote processes when contending to lock a region that
     has just been unlocked - the local lock manager enforces a strict
     first-come first-served model for both local and remote lockers.

   Log:
   Add the new kernel-mode NFS Lock Manager. To use it instead of the
   user-mode lock manager, build a kernel with the NFSLOCKD option and
   add '-k' to 'rpc_lockd_flags' in rc.conf.
   
   Highlights include:
   
   * Thread-safe kernel RPC client - many threads can use the same RPC
     client handle safely with replies being de-multiplexed at the socket
     upcall (typically driven directly by the NIC interrupt) and handed
     off to whichever thread matches the reply. For UDP sockets, many RPC
     clients can share the same socket. This allows the use of a single
     privileged UDP port number to talk to an arbitrary number of remote
     hosts.
   
   * Single-threaded kernel RPC server. Adding support for multi-threaded
     server would be relatively straightforward and would follow
     approximately the Solaris KPI. A single thread should be sufficient
     for the NLM since it should rarely block in normal operation.
   
   * Kernel mode NLM server supporting cancel requests and granted
     callbacks. I've tested the NLM server reasonably extensively - it
     passes both my own tests and the NFS Connectathon locking tests
     running on Solaris, Mac OS X and Ubuntu Linux.
   
   * Userland NLM client supported. While the NLM server doesn't have
     support for the local NFS client's locking needs, it does have to
     field async replies and granted callbacks from remote NLMs that the
     local client has contacted. We relay these replies to the userland
     rpc.lockd over a local domain RPC socket.
   
   * Robust deadlock detection for the local lock manager. In particular
     it will detect deadlocks caused by a lock request that covers more
     than one blocking request. As required by the NLM protocol, all
     deadlock detection happens synchronously - a user is guaranteed that
     if a lock request isn't rejected immediately, the lock will
     eventually be granted. The old system allowed for a 'deferred
     deadlock' condition where a blocked lock request could wake up and
     find that some other deadlock-causing lock owner had beaten them to
     the lock.
   
   * Since both local and remote locks are managed by the same kernel
     locking code, local and remote processes can safely use file locks
     for mutual exclusion. Local processes have no fairness advantage
     compared to remote processes when contending to lock a region that
     has just been unlocked - the local lock manager enforces a strict
     first-come first-served model for both local and remote lockers.

State-Changed-From-To: open->closed 
State-Changed-By: dfr 
State-Changed-When: Tue May 6 16:24:36 UTC 2008 
State-Changed-Why:  
Fixed in the new NFSLOCKD code which is available in: 

RELENG_6 after __FreeBSD_version 603102 
RELENG_7 after __FreeBSD_version 700103 
current after __FreeBSD_version 800028 

To use the new NFS locking server, either add the NFSLOCKD kernel option or 
build the nfslockd.ko and krpc.ko kernel modules.
