From eac03e381957a05f3842ceb8de987a1025966ecf Mon Sep 17 00:00:00 2001 From: Sven Neumann Date: Tue, 30 Aug 2011 23:38:53 +0200 Subject: cfg80211: hold reg_mutex when updating regulatory The function wiphy_update_regulatory() uses the static variable last_request and thus needs to be called with reg_mutex held. This is the case for all users in reg.c, but the function was exported for use by wiphy_register(), from where it is called without the lock being held. Fix this by making wiphy_update_regulatory() private and introducing regulatory_update() as a wrapper that acquires and holds the lock. Signed-off-by: Sven Neumann Cc: John W. Linville Cc: Luis R.
