2020-09-16Bind loopback subnets' lifetime to perm addressGhanan Gowripalan
The lifetime of addreses in a loopback interface's associated subnets should be bound to their respective permanent addresses. This change also fixes a race when the stack attempts to get an IPv4 rereferencedNetworkEndpoint for an address in an associated subnet on a loopback interface. Before this change, the stack would only check if an IPv4 address is contained in an associated subnet while holding a read lock but wouldn't do this same check after releasing the read lock for a write lock to create a temporary address. This may cause the stack to bind the lifetime of the address to a new (temporary) endpoint instead of the associated subnet's permanent address.

When a broadcast packet is received by the stack, the packet should be delivered to each endpoint that may be interested in the packet. This includes all any address and specified broadcast address listeners. Test: integration_test.TestReuseAddrAndBroadcast PiperOrigin-RevId: 332060652

2020-09-15Move reusable IPv4 test code into a testutil module and refactor itArthur Sfez
The refactor aims to simplify the package, by replacing the Go channel with a PacketBuffer slice. This code will be reused by tests for IPv6 fragmentation. PiperOrigin-RevId: 331860411

2020-09-15Don't conclude broadcast from route destinationGhanan Gowripalan
The routing table (in its current) form should not be used to make decisions about whether a remote address is a broadcast address or not (for IPv4). Note, a destination subnet does not always map to a network. E.g. RouterA may have a route to 192.168.0.0/22 through RouterB, but RouterB may be configured with 4x /24 subnets on 4 different interfaces. See https://github.com/google/gvisor/issues/3938.
