2020-01-31Use multicast Ethernet address for multicast NDPGhanan Gowripalan
As per RFC 2464 section 7, an IPv6 packet with a multicast destination address is transmitted to the mapped Ethernet multicast address. Test: - ipv6.TestLinkResolution - stack_test.TestDADResolve - stack_test.TestRouterSolicitation PiperOrigin-RevId: 292610529
2020-01-31iptables: enable TCP matching with "-m tcp".Kevin Krakauer
A couple other things that changed: - There's a proper extension registration system for matchers. Anyone adding another matcher can use tcp_matcher.go or udp_matcher.go as a template. - All logging and use of syserr.Error in the netfilter package happens at the highest possible level (public functions). Lower-level functions just return normal, descriptive golang errors.

2020-01-30Fix for panic in endpoint.Close().Bhasker Hariharan
When sending a RST on shutdown we need to double check the state after acquiring the work mutex as the endpoint could have transitioned out of a connected state from the time we checked it and we acquired the workMutex. I added two tests but sadly neither reproduce the panic. I am going to leave the tests in as they are good to have anyway. PiperOrigin-RevId: 292393800

2020-01-27Expose gonet.NewPacketConn, for parity with gonet.NewConn APIMarek Majkowski
gonet.Conn can be created with both gonet.NewConn and gonet.Dial. gonet.PacketConn was created only by gonet.DialUDP. This prevented us from being able to use PacketConn in udp.NewForwarder() context. This simple constructor - NewPacketConn, allows user to create correct structure from that context.
