A return code of non-zero of the devs ccwgroup set_offline function
leaves the dev in online state. Having done a partly offlining
may leave the dev in unusable state. To make sure the dev is set to
offline, zero is returned. A setup trace entry is written in case
the offlining steps encountered some trouble.

Communication Server Linux uses the ctcmpc code of the ctcm driver.
Sending problems have shown up caused by a wrong idal word list for
the first ccw. Function ctcmpc_chx_txdone() invokes the function
to prepare the idal word list without setting an appropriate length
for the first ccw, which may lead to an incomplete idal word list.
This patch sets the maximum buffer size as data length of the first
ccw. Thus correct idal word lists are guaranteed in all cases.

If a master would like to raise the security level, it will send a
pairing request. While the pending security level is set on an incoming
security request (from a slave), it is not set on a pairing request. As
a result, the security level would not be raised on the slave in such
case.

Fix this by setting the pending security when receiving pairing
requests according to the requested authorization.

commit a8afca03 (tcp: md5: protects md5sig_info with RCU) added a
lockdep splat in tcp_md5_do_lookup() in case a timer fires a tcp
retransmit.

At this point, socket lock is owned by the sofirq handler, not the user,
so we should adjust a bit the lockdep condition, as we dont hold
rcu_read_lock().

This patch allows you to attach the timeout policy via the
CT target, it adds a new revision of the target to ensure
backward compatibility. Moreover, it also contains the glue
code to stick the timeout object defined via nfnetlink_cttimeout
to the given flow.

Example usage (it requires installing the nfct tool and
libnetfilter_cttimeout):

1) create the timeout policy:

 nfct timeout add tcp-policy0 inet tcp \
	established 1000 close 10 time_wait 10 last_ack 10

2) attach the timeout policy to the packet:

 iptables -I PREROUTING -t raw -p tcp -j CT --timeout tcp-policy0

You have to install the following user-space software:

a) libnetfilter_cttimeout:
   git://git.netfilter.org/libnetfilter_cttimeout

b) nfct:
   git://git.netfilter.org/nfct

You also have to get iptables with -j CT --timeout support.

This patch adds the infrastructure to add fine timeout tuning
over nfnetlink. Now you can use the NFNL_SUBSYS_CTNETLINK_TIMEOUT

to conntrack via the CT target and the conntrack extension
infrastructure.

This patch defines a new interface for l4 protocol trackers:

unsigned int *(*get_timeouts)(struct net *net);

that is used to return the array of unsigned int that contains
the timeouts that will be applied for this flow. This is passed
to the l4proto->new(...) and l4proto->packet(...) functions to
specify the timeout policy.

This interface allows per-net global timeout configuration
(although only DCCP supports this by now) and it will allow
custom custom timeout configuration by means of follow-up
patches.
