[Commotion-dev] Possible hostapd / IBSS-RSN regression on OpenWRT AA r36682+

[Ben West]

Hi All,

I'm away from home and not able to easily test this hypothesis, but I see
the recent hostapd update to AA includes 802.11r functionality:
https://dev.openwrt.org/changeset/36533

802.11r, which is now implemented in full hostapd package (as opposed to
hostapd-mini), looks rather useful:
http://en.wikipedia.org/wiki/IEEE_802.11r-2008

While a regression is indeed still possible, I am actually curious if this
hostapd update just means that nodes running r36682+ will not do IBSS-RSN
encryption with nodes running r36681 and earlier.  Not necessarily that
IBSS-RSN fully broken in r36682+.
