From: Johannes Berg Date: Wed, 16 Jan 2008 20:47:40 +0000 (+0100) Subject: mac80211: fix RCU locking in __ieee80211_rx_handle_packet X-Git-Tag: v2.6.25-rc1~1162^2~62 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f99b751fca5b16bea53c0d6724935e1949350052;p=platform%2Fkernel%2Flinux-3.10.git mac80211: fix RCU locking in __ieee80211_rx_handle_packet Commit c7a51bda ("mac80211: restructure __ieee80211_rx") extracted __ieee80211_rx_handle_packet out of __ieee80211_rx and hence changed the locking rules for __ieee80211_rx_handle_packet(), it is now invoked under RCU lock. There is, however, one instance left where it contains an rcu_read_unlock() in an error path, which is a bug. Signed-off-by: Johannes Berg Signed-off-by: John W.
