Re: iwlwifi WPA-TKIP crypto failure after group rekeying

Hi,

To summarise, a WPA-TKIP managed connection stops passing traffic and
the kernel log shows the message "WPA: Group rekeying".  This apparently
doesn't happen if the connection is in heavy use at the time or with
module parameter swcrypto=1.  WPA2 is not affected either.

I think this is due to my patch "iwlagn: rewrite HW crypto" which
accidentally broke key *removal* (of all things), which causes issues
when the first GTK is removed on the second rekeying.

This patch
[...]h=5dcbf480473f6c3f06ad2426b7517038a2a18911

should fix it. Wey has sent it to John

it's also marked for stable.

Shawn Thompson (cc-ed) tested the patch against 3.2.9 and 3.3-rc6 and
found it to work[1].  What can interested people do to help usher this
into mainline?

Great, thanks for testing. The patch is already on the way into mainline
with a Cc:stable tag, so I don't think there's anything to do at this
point.
