From a5c628d290b49688bb4dcbce1b127b5ae4a9d1b4 Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Mon, 18 Oct 2010 17:44:51 -0700 Subject: [PATCH] cfg80211: fix regression on processing country IEs The patch 663dfbb: wireless: only use alpha2 regulatory information from country IE removed some complex intersection we were always doing between the AP's country IE info and what we got from CRDA. When CRDA sent us back a regulatory domain we would do some sanity checks on that regulatory domain response we just got. Part of these sanity checks included checking that we already had performed an intersection for the request of NL80211_REGDOM_SET_BY_COUNTRY_IE type. This mean that cfg80211 was only processing country IEs for cases where we already had an intersection, but since we removed enforcing this this is no longer required, we should just apply the country IE country hint with the data received from CRDA. This patch has fixes intended for kernels >= 2.6.36. Cc: stable@kernel.org Reported-by: Easwar Krishnan Signed-off-by: Luis R. Rodriguez Signed-off-by: John W.
