2020-07-22make connect(2) fail when dest is unreachableKevin Krakauer
Previously, ICMP destination unreachable datagrams were ignored by TCP endpoints. This caused connect to hang when an intermediate router couldn't find a route to the host. This manifested as a Kokoro error when Docker IPv6 was enabled. The Ruby image test would try to install the sinatra gem and hang indefinitely attempting to use an IPv6 address. Fixes #3079.

2019-10-25Validate the checksum for incoming ICMPv6 packetsGhanan Gowripalan
This change validates the ICMPv6 checksum field before further processing an ICMPv6 packet. Tests: Unittests to make sure that only ICMPv6 packets with a valid checksum are accepted/processed. Existing tests using checker.ICMPv6 now also check the ICMPv6 checksum field. PiperOrigin-RevId: 276779148
2019-10-17NDP Neighbor Solicitations sent during DAD must have an IP hop limit of 255Ghanan Gowripalan
NDP Neighbor Solicitations sent during Duplicate Address Detection must have an IP hop limit of 255, as all NDP Neighbor Solicitations should have. Test: Test that DAD messages have the IPv6 hop limit field set to 255. PiperOrigin-RevId: 275321680
2019-10-16Do Duplicate Address Detection on permanent IPv6 addresses.Ghanan Gowripalan
This change adds support for Duplicate Address Detection on IPv6 addresses as defined by RFC 4862 section 5.4. Note, this change will not break existing uses of netstack as the default configuration for the stack options is set in such a way that DAD will not be performed. See `stack.Options` and `stack.NDPConfigurations` for more details. Tests: Tests to make sure that the DAD process properly resolves or fails. That is, tests make sure that DAD resolves only if: - No other node is performing DAD for the same address - No other node owns the same address PiperOrigin-RevId: 275189471
