NFS: hard-code init_net for NFS callback transports

2012-07-16T16:04:40+00:00

upstream commit 12918b10d59e975fd5241eef03ef9e6d5ea3dcfe.

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.

SUNRPC: move per-net operations from svc_destroy()

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

upstream commit 786185b5f8abefa6a8a16695bb4a59c164d5a071.

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

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

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: 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.

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.
