From a3b8b0569fbef725597f05278ec58083321f6e9d Mon Sep 17 00:00:00 2001 From: Jouni Malinen Date: Fri, 27 Mar 2009 21:59:49 +0200 Subject: nl80211: Add Michael MIC failure event Define a new nl80211 event, NL80211_CMD_MICHAEL_MIC_FAILURE, to be used to notify user space about locally detected Michael MIC failures. This matches with the MLME-MICHAELMICFAILURE.indication() primitive. Since we do not actually have TSC in the skb anymore when mac80211_ev_michael_mic_failure() is called, that function is changed to take in the TSC as an optional parameter instead of as a requirement to include the TSC after the hdr field (which we did not really follow). For now, TSC is not included in the events from mac80211, but it could be added at some point. Signed-off-by: Jouni Malinen Signed-off-by: John W.
