SUNRPC: create GSS auth cache per network namespace

2012-02-01T00:28:15+00:00

This patch makes GSS auth cache details allocated and registered per network
namespace context.
Thus with this patch rsi_cache and rsc_cache contents for network namespace "X"
are controlled from proc file system mount for the same network namespace "X".

SUNRPC: create unix gid cache per network namespace

2012-02-01T00:28:15+00:00

v2:
1) fixed silly usage of template cache as a real one (this code left from
static global cache for all)

This patch makes unix_gid_cache cache detail allocated and registered per
network namespace context.
Thus with this patch unix_gid_cache contents for network namespace "X" are
controlled from proc file system mount for the same network namespace "X".

SUNRPC: move rpcbind internals to sunrpc part of network namespace context

2012-02-01T00:28:09+00:00

This patch makes rpcbind logic works in network namespace context. IOW each
network namespace will have it's own unique rpcbind internals (clients and
friends) required for registering svc services per network namespace.

SUNRPC: make SUNPRC clients list per network namespace context

2012-01-31T23:20:25+00:00

This patch moves static SUNRPC clients list and it's lock to sunrpc_net
structure.
Currently this list is used only for debug purposes. But later it will be used
also for selecting clients by networks namespace on PipeFS mount/umount events.
Per-network namespace lists will make this faster and simplier.

Note: client list is taken from "init_net" network namespace context in
rpc_show_tasks(). This will be changed some day later with making SUNRPC
sysctl's per network namespace context.

SUNRPC: pipefs per-net operations helper introduced

2012-01-31T23:20:24+00:00

During per-net pipes creation and destruction we have to make sure, that pipefs
sb exists for the whole creation/destruction cycle. This is done by using
special mutex which controls pipefs sb reference on network namespace context.
Helper consists of two parts: first of them (rpc_get_dentry_net) searches for
dentry with specified name and returns with mutex taken on success. When pipe
creation or destructions is completed, caller should release this mutex by
rpc_put_dentry_net call.

SUNRPC: put pipefs superblock link on network namespace

2012-01-31T23:20:24+00:00

We have modules (like, pNFS blocklayout module) which creates pipes on
rpc_pipefs. Thus we need per-net operations for them. To make it possible we
require appropriate super block. So we have to put sb link on network namespace
context. Note, that it's not strongly required to create pipes in per-net
operations. IOW, if pipefs wasn't mounted yet, that no sb link reference will
present on network namespace and in this case we need just need to pass through
pipe creation. Pipe dentry will be created during pipefs mount notification.

sunrpc: Make the ip_map_cache be per-net

2010-09-27T14:16:12+00:00

Everything that is required for that already exists:
* the per-net cache registration with respective proc entries
* the context (struct net) is available in all the users
