2020-06-11Refactor packetimpact Connection typesgVisor bot
Reorganize the Connection types such that the defined types no longer expose the lower-level functions SendFrame and CreateFrame. These methods are still exported on the underlying Connection type, and thus can be accessed via a type-cast. In future, defined types should have one or more type-safe versions of the send() method on Connection, e.g. UDPIPv4 has Send() which allows the UDP header to be overridden and SendIP() which allows both the IPv4 and UDP headers to be modified. testbench.Connection gets a SendFrameStateless method which sends frames without updating the state of any of the layers. This should be used when sending out-of-band control messages such as ICMP messages, as using the normal Send method can result in errors when attempting to update the TCP state using an ICMP packet. Also remove the localAddr field of testbench.Connection and instead compute it on the fly as needed for UDPIPv4 and TCPIPv4. PiperOrigin-RevId: 315969714

2020-06-10Add support for SO_REUSEADDR to UDP sockets/endpoints.Ian Gudger
On UDP sockets, SO_REUSEADDR allows multiple sockets to bind to the same address, but only delivers packets to the most recently bound socket. This differs from the behavior of SO_REUSEADDR on TCP sockets. SO_REUSEADDR for TCP sockets will likely need an almost completely independent implementation. SO_REUSEADDR has some odd interactions with the similar SO_REUSEPORT. These interactions are tested fairly extensively and all but one particularly odd one (that honestly seems like a bug) behave the same on gVisor and Linux. PiperOrigin-RevId: 315844832
