[IPV6]: Unify ip6_onlink() and ipip6_onlink().
Both are identical, let's create ipv6_chk_prefix() and use it
in both places.

[VLAN]: Proc entry is not renamed when vlan device name changes.
This may lead to situations, when each of two proc entries produce
data for the other's device.

Looks like a BUG, so this patch is for net-2.6. It will not apply to
net-2.6.26 since dev->nd_net access is replaced with dev_net(dev)
one.

bluetooth : __rfcomm_dlc_close lock fix
Lockdep warning will be trigged while rfcomm connection closing.

The locks taken in rfcomm_dev_add:
rfcomm_dev_lock --> d->lock

In __rfcomm_dlc_close:
d->lock --> rfcomm_dev_lock (in rfcomm_dev_state_change)

There's two way to fix it, one is in rfcomm_dev_add we first locking
d->lock then the rfcomm_dev_lock

The other (in this patch), remove the locking of d->lock for
rfcomm_dev_state_change because just locking "d->state = BT_CLOSED;"
is enough.

bluetooth : use lockdep sub-classes for diffrent bluetooth protocol
'rfcomm connect' will trigger lockdep warnings which is caused by
locking diffrent kinds of bluetooth sockets at the same time.

So using sub-classes per AF_BLUETOOTH sub-type for lockdep.

Thanks for the hints from dave jones.

[ROSE/AX25] af_rose: rose_release() fix
rose_release() doesn't release sockets properly, e.g. it skips
sock_orphan(), so OOPSes are triggered in sock_def_write_space(),
which was observed especially while ROSE skbs were kfreed from
ax25_frames_acked(). There is also sock_hold() and lock_sock() added -
similarly to ax25_release(). Thanks to Bernard Pidoux for substantial

Also clean up the code doing it internally to be a bit clearer and

mac80211: automatically free sta struct when insertion fails
When STA structure insertion fails, it has been allocated but isn't
really alive yet, it isn't reachable by any other code and also can't
yet have much configured. This patch changes the code so that when
the insertion fails, the resulting STA pointer is no longer valid
because it is freed.

mac80211: fix sta_info_destroy(NULL)
sta_info_destroy(NULL) should be valid, but currently isn't because
the argument is dereferenced before the NULL check. There are no
users that currently pass in NULL, i.e. all check before calling the
function, but I want to change that.

mac80211: trigger ieee80211_sta_work after opening interface
ieee80211_sta_work is disabled while network interface
is down. Therefore, if you configure wireless parameters
before bringing the interface up, these configurations are
not yet effective and association fails.

A workaround from userspace is calling a command like
'iwconfig wlan0 ap any' after the interface is brought up.

To fix this behaviour, trigger execution of ieee80211_sta_work from
ieee80211_open when in STA or IBSS mode.

[SOCK][NETNS]: Add the percpu prot_inuse counter in the struct net.
Such an accounting would cost us two more dereferences to get the
percpu variable from the struct net, so I make sock_prot_inuse_get
and _add calls work differently depending on CONFIG_NET_NS - without
it old optimized routines are used.

The per-cpu counter for init_net is prepared in core_initcall, so
that even af_inet, that starts as fs_initcall, will already have the
init_net prepared.

This counter is about to become per-proto-and-per-net, so we'll need 
two arguments to determine which cell in this "table" to work with.

All the places, but proc already pass proper net to it - proc will be
tuned a bit later.

Some indentation with spaces in proc files is done to keep the file
coding style consistent.

[IPV6] MCAST: Ensure to check multicast listener(s).
In ip6_mc_input(), we need to check whether we have listener(s) for
the packet.

After commit ae7bf20a63, all packets
for multicast destinations are delivered to upper layer if
IFF_PROMISC or IFF_ALLMULTI is set.

In fact, bug was rather ancient; the original (before the commit)
intent of the dev->flags check was to skip the ipv6_chk_mcast_addr()
call, assuming L2 filters packets appropriately, but it was even not
true.

Let's explicitly check our multicast list.
