2011-07-16svcrpc: fix list-corrupting race on nfsd shutdownJ. Bruce Fields1-5/+6
After commit 3262c816a3d7fb1eaabce633caa317887ed549ae "[PATCH] knfsd: split svc_serv into pools", svc_delete_xprt (then svc_delete_socket) no longer removed its xpt_ready (then sk_ready) field from whatever list it was on, noting that there was no point since the whole list was about to be destroyed anyway. That was mostly true, but forgot that a few svc_xprt_enqueue()'s might still be hanging around playing with the about-to-be-destroyed list, and could get themselves into trouble writing to freed memory if we left this xprt on the list after freeing it. (This is actually functionally identical to a patch made first by Ben Greear, but with more comments.)

2011-07-16nfsd: Remove deprecated nfsctl system call and related code.NeilBrown1-78/+0
As promised in feature-removal-schedule.txt it is time to remove the nfsctl system call. Userspace has perferred to not use this call throughout 2.6 and it has been excluded in the default configuration since 2.6.36 (9 months ago). So this patch removes all the code that was being compiled out. There are still references to sys_nfsctl in various arch systemcall tables and related code. These should be cleaned out too, probably in the next merge window. Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: J. Bruce Fields <bfields@redhat.com>

2011-05-28SUNRPC: Support for RPC over AF_LOCAL transportsChuck Lever2-3/+400
TI-RPC introduces the capability of performing RPC over AF_LOCAL sockets. It uses this mainly for registering and unregistering local RPC services securely with the local rpcbind, but we could also conceivably use it as a generic upcall mechanism. This patch provides a client-side only implementation for the moment. We might also consider a server-side implementation to provide AF_LOCAL access to NLM (for statd downcalls, and such like). Autobinding is not supported on kernel AF_LOCAL transports at this time. Kernel ULPs must specify the pathname of the remote endpoint when an AF_LOCAL transport is created. rpcbind supports registering services available via AF_LOCAL, so the kernel could handle it with some adjustment to ->rpcbind and ->set_port. But we don't need this feature for doing upcalls via well-known named sockets. This has not been tested with ULPs that move a substantial amount of data. Thus, I can't attest to how robust the write_space and congestion management logic is. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

Clean up. The documenting comment at the top of net/sunrpc/clnt.c is out of date. We adopted BSD's RTO estimation mechanism years ago. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
