Now, iptables show and configure different set of rules in different
netnss'. Filtering decisions are still made by consulting only
init_net's set.

Changes are identical except naming so no splitting.

P.S.: one need to remove init_net checks in nf_sockopt.c and inet_create()
      to see the effect.

[NETNS]: Fix race between put_net() and netlink_kernel_create().

The comment about "race free view of the set of network
namespaces" was a bit hasty. Look (there even can be only
one CPU, as discovered by Alexey Dobriyan and Denis Lunev):

put_net()
  if (atomic_dec_and_test(&net->refcnt))
    /* true */
      __put_net(net);
        queue_work(...);

/*
 * note: the net now has refcnt 0, but still in
 * the global list of net namespaces
 */

== re-schedule ==

register_pernet_subsys(&some_ops);
  register_pernet_operations(&some_ops);
    (*some_ops)->init(net);
      /*

       * in some places
       */
      netlink_kernel_create();
         sk_alloc();
            get_net(net); /* refcnt = 1 */
         /*
          * now we drop the net refcount not to
          * block the net namespace exit in the
          * future (or this can be done on the

                   /*
                    * true. BOOOM! The net is
                    * scheduled for release twice
                    */

When thinking on this problem, I decided, that getting and
putting the net in init callback is wrong. If some init
callback needs to have a refcount-less reference on the struct
net, _it_ has to be careful himself, rather than relying on
the infrastructure to handle this correctly.

In case of netlink_kernel_create(), the problem is that the
sk_alloc() gets the given namespace, but passing the info
that we don't want to get it inside this call is too heavy.

Instead, I propose to crate the socket inside an init_net
namespace and then re-attach it to the desired one right
after the socket is created.

After doing this, we also have to be careful on error paths
not to drop the reference on the namespace, we didn't get
the one on.

[INET_DIAG]: Fix inet_diag_lock_handler error path.

Fixes: http://bugzilla.kernel.org/show_bug.cgi?id=9825
The inet_diag_lock_handler function uses ERR_PTR to encode errors but
its callers were testing against NULL.

This only happens when the only inet_diag modular user, DCCP, is not
built into the kernel or available as a module.

Also there was a problem with not dropping the mutex lock when a handler
was not found, also fixed in this patch.

This caused an OOPS and ss would then hang on subsequent calls, as
&inet_diag_table_mutex was being left locked.

Thanks to spike at ml.yaroslavl.ru for report it after trying 'ss -d'
on a kernel that doesn't have DCCP available.

This bug was introduced in cset
d523a328fb0271e1a763e985a21f2488fd816e7e ("Fix inet_diag dead-lock

iwlwifi: initialize geo/channel information during probe

The geo/channel information is obtained from the EEPROM, which is read
during probe. We can thus set up channel information at this time. This
helps us to support ioctl commands that rely on this before the interface
is brought up.

Clearly matches _init_channel_map with _free_channel_map and _init_geos
with _free_geos to ensure functions calling these routines can also call
their cleanup routines.

Fixes a few bugs:
- if channel information is not available when ioctl commands are
  issued then we get a NULL pointer oops. Having channel information
  set up during probe we can deal with ioctl commands without requiring
  interface to be brought up.
  This fixes bug: http://www.bughost.org/bugzilla/show_bug.cgi?id=1552
- Fix potential problem if user triggers probe/remove/probe sequence. The
  value of priv->channel_count was used to determine if channel map is
  set up. This value was never reset when channel map was removed.

sched: fix high wake up latencies with FAIR_USER_SCHED

The reason why we are getting better wakeup latencies for
!FAIR_USER_SCHED is because of this snippet of code in place_entity():

if (!initial) {
/* sleeps upto a single latency don't count. */
if (sched_feat(NEW_FAIR_SLEEPERS) && entity_is_task(se))
     ^^^^^^^^^^^^^^^^^^
vruntime -= sysctl_sched_latency;

/* ensure we never gain time by being placed backwards. */
vruntime = max_vruntime(se->vruntime, vruntime);
}

NEW_FAIR_SLEEPERS feature gives credit for sleeping only to tasks and
not group-level entities. With the patch attached, I could see that
wakeup latencies with FAIR_USER_SCHED are restored to the same level as
!FAIR_USER_SCHED.
