From 28a9bc68124c319b2b3dc861e80828a8865fd1ba Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 17 Dec 2014 13:55:49 +0100 Subject: [PATCH] mac80211: free management frame keys when removing station When writing the code to allow per-station GTKs, I neglected to take into account the management frame keys (index 4 and 5) when freeing the station and only added code to free the first four data frame keys. Fix this by iterating the array of keys over the right length.
