Reversed Locking Order in legacy_drivers.cpp

Reported by: bonefish Owned by: axeld
Priority: normal Milestone: R1
Component: System/Kernel Version: R1/Development

Blocked By: Blocking:
Platform: All

Description

legacy_drivers.cpp calls {add,remove}_node_listener() for sDriverWatcher with sLock held. DriverWatcher::EventOccured() acquires sLock, too. Since the node monitoring service has an internal lock it acquires in {add,remove}_node_listener() and also holds when calling the listeners' EventOccurred(), we have contradicting locking orders for the two cases.
