Description
A race condition in the logic of interface down handling leads to leaking of the socket and other resources.
The sock_usage ref count is checked to be 0 in AFPSwitchState. If it is, the resources are freed. If it isn't, which is a common thing in autofp, there are never freed and AFPTryReopen will overwrite the socket and other resources.
