ip-neighbor: GARP sent to bogus ip address
The function ip4_neighbor_advertise may be called with NULL addr. In that case, it looks up addr from fib by calling fib_sas4_get which returns true or false to indicate whether there is an ip address associated with the interface or not. But the caller to fib_sas4_get does not check the return code and blindly assumes there is always an ip address associated with the interface. As a result, it ends up sending GARP to the bogus ip address if there is no ip address associated with the interface.
