It seems I was actually able to hit this deadlock, on my quad G5 softmac
locks up more often than not. This fixes it by using an own workqueue
that can safely be flushed under RTNL.
Not sure if the patch is correct with the workqueue naming. And don't
think with the patch it doesn't continually lock up. It still does, just
doesn't invoke lockdep warnings all the time.

SSB is an SoC bus used in a number of embedded devices. The most
well-known of these devices is probably the Linksys WRT54G, but there
are others as well. The bus is also used internally on the BCM43xx
and BCM44xx devices from Broadcom.
This patch also includes support for SSB ID tables in modules, so
that SSB drivers can be loaded automatically.

I proposed introducing a list_for_each_entry_continue_reverse macro
to be used in setup_net() when unrolling the failed ->init callback.
Here is the macro and some more cleanup in the setup_net() itself
to remove one variable from the stack :) The same thing is for the
cleanup_net() - the existing list_for_each_entry_reverse() is used.
Minor, but the code looks nicer.

SCTP-AUTH, Section 6.2:
Endpoints MUST send all requested chunks authenticated where this has
been requested by the peer. The other chunks MAY be sent
authenticated or not. If endpoint pair shared keys are used, one of
them MUST be selected for authentication.
To send chunks in an authenticated way, the sender MUST include these
chunks after an AUTH chunk. This means that a sender MUST bundle
chunks in order to authenticate them.
If the endpoint has no endpoint pair shared key for the peer, it MUST
use Shared Key Identifier 0 with an empty endpoint pair shared key.
If there are multiple endpoint shared keys the sender selects one and
uses the corresponding Shared Key Identifier

Background: RFC 4293 deprecates existing individual, named ICMP
type counters to be replaced with the ICMPMsgStatsTable. This table
includes entries for both IPv4 and IPv6, and requires counting of all
ICMP types, whether or not the machine implements the type.
These patches "remove" (but not really) the existing counters, and
replace them with the ICMPMsgStats tables for v4 and v6.
It includes the named counters in the /proc places they were, but gets the
values for them from the new tables. It also counts packets generated
from raw socket output (e.g., OutEchoes, MLD queries, RA's from
radvd, etc).
Changes:
1) create icmpmsg_statistics mib
2) create icmpv6msg_statistics mib
3) modify existing counters to use these
4) modify /proc/net/snmp to add "IcmpMsg" with all ICMP types
listed by number for easy SNMP parsing
5) modify /proc/net/snmp printing for "Icmp" to get the named data
from new counters.

It contains a list of chunks that a particular SCTP extension
uses. Current extensions supported are Partial Reliability
(FWD-TSN) and ADD-IP (ASCONF and ASCONF-ACK).
When implementing new extensions (AUTH, PKT-DROP, etc..), new
chunks need to be added to this parameter. Parameter processing
would be modified to negotiate support for these new features.

We now have struct net_device_stats embedded in struct net_device,
and the default ->get_stats() hook does the obvious thing for us.
Run through drivers/net/* and remove the driver-local storage of
statistics, and driver-local ->get_stats() hook where applicable.
This was just the low-hanging fruit in drivers/net; plenty more drivers
remain to be updated.

The TKIP mixing code was added for the benefit of Intel's ipw3945
chipset but that code ended up not using it. We have previously
identified many problems with this code and it crystallized that
library functions for mixing are likely to handle this in much
more generality and might allow b43 to take advantage of hardware
acceleration for TKIP.
Due to these reasons, remove the TKIP mixing for hardware
accelerated crypto operations.

This patch makes the mac80211/driver interface rely only on the
IEEE80211_TXCTL_DO_NOT_ENCRYPT flag to signal to the driver whether
a frame should be encrypted or not, since mac80211 internally no
longer relies on HW_KEY_IDX_INVALID either this removes it, changes
the key index to be a u8 in all places and makes the full range of
the value available to drivers.

No existing drivers use this callback, hence there's no telling
how it might be used. In fact, it is unlikely to be of much use
as-is because the default key index isn't something that the
driver can do much with without knowing which interface it was
for etc. And if it needs the key index for the transmitted frame,
it can get it by keeping a reference to the key_conf structure
and looking it up by hw_key_idx.

As Dmitry pointed out earlier, rfkill-input.c

and we shouldn't add unrequired KEY_ defines.
However, RFKILL_TYPE_IRDA was defined in the

about whether it is implemented or not.

The problem: proc_net files remember which network namespace the are
against but do not remember hold a reference count (as that would pin
the network namespace). So we currently have a small window where
the reference count on a network namespace may be incremented when opening
a /proc file when it has already gone to zero.
To fix this introduce maybe_get_net and get_proc_net.
maybe_get_net increments the network namespace reference count only if it is
greater then zero, ensuring we don't increment a reference count after it
has gone to zero.
get_proc_net handles all of the magic to go from a proc inode to the network
namespace instance and call maybe_get_net on it.
PROC_NET the old accessor is removed so that we don't get confused and use
the wrong helper function.
Then I fix up the callers to use get_proc_net and handle the case case
where get_proc_net returns NULL. In that case I return -ENXIO because
effectively the network namespace has already gone away so the files
we are trying to access don't exist anymore.
