NFS: hard-code init_net for NFS callback transports

2012-06-14T17:53:43+00:00

In case of destroying mount namespace on child reaper exit, nsproxy is zeroed to the point already. So, dereferencing of it is invalid. This patch hard-code "init_net" for all network namespace references for NFS callback services. This will be fixed with proper NFS callback containerization.

nfsd4: move principal name into svc_cred

2012-06-01T00:29:55+00:00

Instead of keeping the principal name associated with a request in a structure that's private to auth_gss and using an accessor function, move it to svc_cred. Signed-off-by: J. Bruce Fields

SUNRPC: move per-net operations from svc_destroy()

2012-06-01T00:29:40+00:00

The idea is to separate service destruction and per-net operations, because these are two different things and the mix looks ugly. Notes: 1) For NFS server this patch looks ugly (sorry for that). But these place will be rewritten soon during NFSd containerization. 2) LockD per-net counter increase int lockd_up() was moved prior to make_socks() to make lockd_down_net() call safe in case of error.

SUNRPC: new svc_bind() routine introduced

2012-06-01T00:29:39+00:00

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

NFS: Fix a number of sparse warnings

2012-03-11T19:14:16+00:00

Fix a number of "warning: symbol 'foo' was not declared. Should it be static?" conditions. Fix 2 cases of "warning: Using plain integer as NULL pointer" fs/nfs/delegation.c:263:31: warning: restricted fmode_t degrades to integer - We want to allow upgrades to a WRITE delegation, but should otherwise consider servers that hand out duplicate delegations to be borken.

SUNRPC: Move clnt->cl_server into struct rpc_xprt

2012-03-02T20:36:41+00:00

When the cl_xprt field is updated, the cl_server field will also have to change. Since the contents of cl_server follow the remote endpoint of cl_xprt, just move that field to the rpc_xprt.

NFS: start printks w/ NFS: even if func shown

2012-02-06T23:48:00+00:00

This patch addresses printks that have some context to show that they are from fs/nfs/, but for the sake of consistency now start with NFS: Signed-off-by: Weston Andros Adamson Signed-off-by: Trond Myklebust

NFS: create callback transports in parent transport network namespace

2012-01-31T23:20:27+00:00

This patch replaces static "init_net" references with parent transport xprt_net reference. Thus callback transports will be created in the same network namespace as respective NFS mount point was created. Signed-off-by: Stanislav Kinsbursky Signed-off-by: Trond Myklebust

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.

NFS do not find client in NFSv4 pg_authenticate

2011-01-25T20:26:51+00:00

The information required to find the nfs_client cooresponding to the incoming back channel request is contained in the NFS layer. Perform minimal checking in the RPC layer pg_authenticate method, and push more detailed checking into the NFS layer where the nfs_client can be found.
