From 20658702e08ecd693236b443837d28863b93e872 Mon Sep 17 00:00:00 2001 From: Arik Nemtsov Date: Mon, 29 Dec 2014 11:59:59 +0200 Subject: [PATCH] cfg80211: fix deadlock during reg chan check If a P2P GO is active, the cfg80211_reg_can_beacon function will take the wdev lock, in its call to cfg80211_go_permissive_chan. But the wdev lock is already taken by the parent channel-checking function, causing a deadlock. Split the checking code into two parts. The first part will check if the wdev is active and saves the channel under the wdev lock. The second part will check actual channel validity according to type.
