SUNRPC: new svc_bind() routine introduced

2012-07-16T16:04:39+00:00

upstream commit 9793f7c88937e7ac07305ab1af1a519225836823. 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 Signed-off-by: J. Bruce Fields Signed-off-by: Greg Kroah-Hartman

Lockd: per-net up and down routines introduced

2012-02-15T05:19:47+00:00

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. Signed-off-by: Stanislav Kinsbursky Signed-off-by: Trond Myklebust

SUNRPC: unregister service on creation in current network namespace

2012-02-01T00:28:14+00:00

On service shutdown we can be sure, that no more users of it left except current. Thus it looks like using current network namespace context is safe in this case. Signed-off-by: Stanislav Kinsbursky Signed-off-by: Trond Myklebust

SUNRPC: pass network namespace to service registering routines

2012-02-01T00:28:13+00:00

Lockd and NFSd services will handle requests from and to many network nsamespaces. And thus have to be registered and unregistered per network namespace. Signed-off-by: Stanislav Kinsbursky Signed-off-by: Trond Myklebust

NFSd: call svc rpcbind cleanup explicitly

2011-10-25T11:19:40+00:00

We have to call svc_rpcb_cleanup() explicitly from nfsd_last_thread() since this function is registered as service shutdown callback and thus nobody else will done it for us. Signed-off-by: Stanislav Kinsbursky Signed-off-by: Trond Myklebust

SUNRPC: Replace svc_addr_u by sockaddr_storage

2011-09-14T12:21:48+00:00

For IPv6 local address, lockd can not callback to client for missing scope id when binding address at inet6_bind: 324 if (addr_type & IPV6_ADDR_LINKLOCAL) { 325 if (addr_len >= sizeof(struct sockaddr_in6) && 326 addr->sin6_scope_id) { 327 /* Override any existing binding, if another one 328 * is supplied by user. 329 */ 330 sk->sk_bound_dev_if = addr->sin6_scope_id; 331 } 332 333 /* Binding to link-local address requires an interface */ 334 if (!sk->sk_bound_dev_if) { 335 err = -EINVAL; 336 goto out_unlock; 337 } Replacing svc_addr_u by sockaddr_storage, let rqstp->rq_daddr contains more info besides address.

sunrpc: use better NUMA affinities

2011-08-19T17:25:36+00:00

Use NUMA aware allocations to reduce latencies and increase throughput. sunrpc kthreads can use kthread_create_on_node() if pool_mode is "percpu" or "pernode", and svc_prepare_thread()/svc_init_buffer() can also take into account NUMA node affinity for memory allocations.

nfsd: turn on reply cache for NFSv4

2011-07-18T13:39:01+00:00

It's sort of ridiculous that we've never had a working reply cache for NFSv4. On the other hand, we may still not: our current reply cache is likely not very good, especially in the TCP case (which is the only case that matters for v4). What we really need here is some serious testing. Anyway, here's a start. Signed-off-by: J. Bruce Fields
