From 97ebe12a035e11f8af7a06a34f4d848f9b2f0b49 Mon Sep 17 00:00:00 2001 From: Jouni Malinen Date: Thu, 8 Jan 2009 13:32:08 +0200 Subject: [PATCH] mac80211: 802.11w - Drop unprotected robust management frames if MFP is used Use ieee80211_drop_unencrypted() to decide whether a received frame should be dropped with management frames, too. If MFP is negotiated, unprotected robust management frames will be dropped. Signed-off-by: Jouni Malinen Acked-by: Johannes Berg Signed-off-by: John W.
