[Bug 580753] Re: ath9k module causing MIC challenge failures

[Jouni Malinen]

Thanks. Based on the information here so far, this looks likely to be a
race condition in either ath9k or mac80211 which would end up in
triggering incorrect Michael MIC failure event immediately after the
group key is configured (i.e., a broadcast frame being received from the
AP at more or less the exact same time when the key is being set).

Quick review of the current implementation did not result in me finding
any clear problems in this area. As such, I would like to be able to
figure out how to reproduce this without having to use a large number of
client devices and to wait for hours.. If that turns out to be too
difficult, another option would be in adding some more debugging code
into the kernel code to figure out what exactly is the place where this
event is generated and under what conditions. Would you be willing to
run such a test if needed (i.e., to patch the kernel source code and
build your own kernel)?
