When regulatory information changes our HT behavior (e.g,
when we get a country code from the AP we have just associated
with), we should use this information to change the power with
which we transmit, and what channels we transmit. Sometimes
the channel parameters we derive from regulatory information
contradicts the parameters we used in association. For example,
we could have associated specifying HT40, but the regulatory
rules we apply may forbid HT40 operation.
In the situation above, we should reconfigure ourselves to
transmit in HT20 only, however it makes no sense for us to
disable receive in HT40, since if we associated with these
parameters, the AP has every reason to expect we can and
will receive packets this way. The code in mac80211 does
not have the capability of sending the appropriate action
frames to signal a change in HT behaviour so the AP has
no clue we can no longer receive frames encoded this way.
In some broken AP implementations, this can leave us
effectively deaf if the AP never retries in lower HT rates.
This change breaks up the channel_type parameter in the
ieee80211_enable_ht function into a separate receive and
transmit part. It honors the channel flags set by regulatory
in order to configure the rate control algorithm, but uses
the capability flags to configure the channel on the radio,
since these were used in association to set the AP's transmit
rate.

As we've discussed, we want to avoid channel changes
while associated. While the part when we actually
associate needs a bit more work, the bit that happens
on disassociating can be changed quite easily. Move
the channel type change later in the disassociate
process to set the channel only after the driver was
told that it's now disassociated.
As the driver could expect powersave to be enabled

added a serious regression on synflood handling.
Simon Kirby discovered a successful connection was delayed by 20 seconds

In my tests, I discovered that xmit frames were lost, and needed ~4
retransmits and a socket dst rebuild before being really sent.
In case of syncookie initiated connection, we use a different path to
initialize the socket dst, and inet->cork.fl.u.ip4 is left cleared.
As ip_queue_xmit() now depends on inet flow being setup, fix this by

mac80211 is lenient with respect to reception of corrupted beacons.
Even if the frame is corrupted as a whole, the available IE elements
are still passed back and accepted, sometimes replacing legitimate
data. It is unknown to what extent this "feature" is made use of,
but it is clear that in some cases, this is detrimental. One such
case is reported in http://crosbug.com/26832 where an AP corrupts
its beacons but not its probe responses.
One approach would be to completely reject frames with invaid data
(for example, if the last tag extends beyond the end of the enclosing
PDU). The enclosed approach is much more conservative: we simply
prevent later IEs from overwriting the state from previous ones.
This approach hopes that there might be some salient data in the
IE stream before the corruption, and seeks to at least prevent that
data from being overwritten. This approach will fix the case above.
Further, we flag element structures that contain data we think might
be corrupted, so that as we fill the mac80211 BSS structure, we try
not to replace data from an un-corrupted probe response with that
of a corrupted beacon, for example.
Short of any statistics gathering in the various forms of AP breakage,
it's not possible to ascertain the side effects of more stringent
discarding of data.

backward compatibility. Moreover, it also contains the glue

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:
