From: Ivo van Doorn Date: Mon, 5 May 2008 18:40:35 +0000 (+0200) Subject: mac80211: Don't encrypt beacons X-Git-Tag: v2.6.26-rc3~65^2~14^2~11 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=df44205455773852a6af10a7c6ed768fe8a86b31;p=linux-2.6-omap-h63xx.git mac80211: Don't encrypt beacons mac80211 should set the IEEE80211_TX_CTL_DO_NOT_ENCRYPT flag in tx_control structure to inform drivers not to encrypt the beacon. Drivers that only check for that flag before accessing the hw_key field, will otherwise cause a NULL pointer dereference since that field is not configured for beacons.
