From b2898a27809f54a33050a70d0eaa4a78194163a0 Mon Sep 17 00:00:00 2001 From: Ivo van Doorn Date: Tue, 1 Jul 2008 10:45:13 +0200 Subject: [PATCH] mac80211: Don't request encryption for probe response Probe responses shouldn't be encrypted, and mac80211 doesn't set the crypto key accordingly. However it didn't set the IEEE80211_TX_CTL_DO_NOT_ENCRYPT flag which means drivers could make an attempt to encrypt it, and causing a NULL pointer dereference when accessing the provided hw_key field.
