2020-03-27Support Hop By Hop and Destination Options ext hdrGhanan Gowripalan
Enables handling the Hop by Hop and Destination Options extension headers, but options are not yet supported. All options will be treated as unknown and their respective action will be followed. Note, the stack does not yet support sending ICMPv6 error messages in response to options that cannot be handled/parsed. That will come in a later change (Issue #2211). Tests: - header_test.TestIPv6UnknownExtHdrOption - header_test.TestIPv6OptionsExtHdrIterErr - header_test.TestIPv6OptionsExtHdrIter - ipv6_test.TestReceiveIPv6ExtHdrs PiperOrigin-RevId: 303433085

2020-03-26Handle IPv6 Fragment & Routing extension headersGhanan Gowripalan
Enables the reassembly of fragmented IPv6 packets and handling of the Routing extension header with a Segments Left value of 0. Atomic fragments are handled as described in RFC 6946 to not interfere with "normal" fragment traffic. No specific routing header type is supported. Note, the stack does not yet support sending ICMPv6 error messages in response to IPv6 packets that cannot be handled/parsed. That will come in a later change (Issue #2211). Test: - header_test.TestIPv6RoutingExtHdr - header_test.TestIPv6FragmentExtHdr - header_test.TestIPv6ExtHdrIterErr - header_test.TestIPv6ExtHdrIter - ipv6_test.TestReceiveIPv6ExtHdrs - ipv6_test.TestReceiveIPv6Fragments RELNOTES: n/a PiperOrigin-RevId: 303189584
2020-03-26Support owner matching for iptables.Nayana Bidari
This feature will match UID and GID of the packet creator, for locally generated packets. This match is only valid in the OUTPUT and POSTROUTING chains. Forwarded packets do not have any socket associated with them. Packets from kernel threads do have a socket, but usually no owner.

When list elements are removed from a list but not discarded, it becomes important to invalidate the references they hold to their former neighbors to prevent memory leaks. PiperOrigin-RevId: 299412421

2020-02-24Add support for tearing down protocol dispatchers and TIME_WAIT endpoints.Ian Gudger
Protocol dispatchers were previously leaked. Bypassing TIME_WAIT is required to test this change. Also fix a race when a socket in SYN-RCVD is closed. This is also required to test this change. PiperOrigin-RevId: 296922548

2020-01-09New sync package.Ian Gudger
* Rename syncutil to sync. * Add aliases to sync types. * Replace existing usage of standard library sync package. This will make it easier to swap out synchronization primitives. For example, this will allow us to use primitives from github.com/sasha-s/go-deadlock to check for lock ordering violations. Updates #1472 PiperOrigin-RevId: 289033387
