sunrpc: move address copy/cmp/convert routines and prototypes from clnt.h to addr.h

2013-02-05T14:41:14+00:00

These routines are used by server and client code, so having them in a
separate header would be best.

LOCKD: Clear ln->nsm_clnt only when ln->nsm_users is zero

The current code is clearing it in all cases _except_ when zero.

LOCKD: fix races in nsm_client_get

2012-10-24T14:46:22+00:00

Commit e9406db20fecbfcab646bad157b4cfdc7cadddfb (lockd: per-net
NSM client creation and destruction helpers introduced) contains
a nasty race on initialisation of the per-net NSM client because
it doesn't check whether or not the client is set after grabbing
the nsm_create_mutex.

lockd: create and use per-net NSM RPC clients on MON/UNMON requests

2012-10-01T22:27:43+00:00

NSM RPC client can be required on NFSv3 umount, when child reaper is dying
(and destroying it's mount namespace). It means, that current nsproxy is set
to NULL already, but creation of RPC client requires UTS namespace for gaining
hostname string.

This patch creates reference-counted per-net NSM client on first monitor
request and destroys it after last unmonitor request.

lockd: use rpc client's cl_nodename for id encoding

2012-10-01T22:27:38+00:00

Taking hostname from uts namespace if not safe, because this cuold be
performind during umount operation on child reaper death. And in this case
current->nsproxy is NULL already.

lockd: per-net NSM client creation and destruction helpers introduced

2012-10-01T22:27:34+00:00

NSM RPC client can be required on NFSv3 umount, when child reaper is dying (and
destroying it's mount namespace). It means, that current nsproxy is set to
NULL already, but creation of RPC client requires UTS namespace for gaining
hostname string.
This patch introduces reference counted NFS RPC clients creation and
destruction helpers (similar to RPCBIND RPC clients).

LockD: make NSM network namespace aware

2012-02-15T05:19:48+00:00

NLM host is network namespace aware now.
So NSM have to take it into account.

module_param: make bool parameters really bool (drivers & misc)

2012-01-12T23:02:20+00:00

module_param(bool) used to counter-intuitively take an int.  In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.

It's time to remove the int/unsigned int option.  For this version
it'll simply give a warning, but it'll break next kernel version.
