From f612cedfe152b536197c0120f2e7779bc90219d0 Mon Sep 17 00:00:00 2001 From: Jouni Malinen Date: Thu, 11 Aug 2011 11:46:22 +0300 Subject: nl80211/cfg80211: Make addition of new sinfo fields safer Add a comment pointing out the use of enum station_info_flags for all new struct station_info fields. In addition, memset the sinfo buffer to zero before use on all paths in the current tree to avoid leaving uninitialized pointers in the data. Signed-off-by: Jouni Malinen Signed-off-by: John W.
