* mac80211: fix CMAC racesJohannes Berg2011-07-081-1/+1
| | | | | | | | | | | | Just like TKIP and CCMP, CMAC has the PN race. It might not actually be possible to hit it now since there aren't multiple ACs for management frames, but fix it anyway. Also move scratch buffers onto the stack. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mac80211: 802.11w - Add BIP (AES-128-CMAC)Jouni Malinen2009-01-291-0/+19
Implement Broadcast/Multicast Integrity Protocol for management frame protection. This patch adds the needed definitions for the new information element (MMIE) and implementation for the new "encryption" type (though, BIP is actually not encrypting data, it provides only integrity protection). These routines will be used by a follow-on patch that enables BIP for multicast/broadcast robust management frames.
