| |
2.6.29-stable review patch. If anyone has any objections, please let us know.
------------------
From: Johannes Berg <johannes@sipsolutions.net>
upstream commit: 7e0986c17f695952ce5d61ed793ce048ba90a661
"mac80211: fix basic rates setting from association response" introduced a copy/paste error.
Unfortunately, this not just leads to wrong data being passed to the driver but is remotely exploitable for some hardware or driver combinations.
