Sven Eckelmann 1181e1daac batman-adv: Make vis info stack traversal threadsafe ... The batman-adv vis server has to a stack which stores all information about packets which should be send later. This stack is protected with a spinlock that is used to prevent concurrent write access to it. The send_vis_packets function has to take all elements from the stack and send them to other hosts over the primary interface. The send will be initiated without the lock which protects the stack. The implementation using list_for_each_entry_safe has the problem that it stores the next element as "safe ptr" to allow the deletion of the current element in the list. The list may be modified during the unlock/lock pair in the loop body which may make the safe pointer not pointing to correct next element. It is safer to remove and use the first element from the stack until no elements are available. This does not need reduntant information which would have to be validated each time the lock was removed.
