2021-01-13Do not resolve remote link address at transport layerGhanan Gowripalan
Link address resolution is performed at the link layer (if required) so we can defer it from the transport layer. When link resolution is required, packets will be queued and sent once link resolution completes. If link resolution fails, the transport layer will receive a control message indicating that the stack failed to route the packet. tcpip.Endpoint.Write no longer returns a channel now that writes do not wait for link resolution at the transport layer. tcpip.ErrNoLinkAddress is no longer used so it is removed. Removed calls to stack.Route.ResolveWith from the transport layer so that link resolution is performed when a route is created in response to an incoming packet (e.g. to complete TCP handshakes or send a RST). Tests: - integration_test.TestForwarding - integration_test.TestTCPLinkResolutionFailure Fixes #4458 RELNOTES: n/a PiperOrigin-RevId: 351684158

2021-01-12Fix Go branch building.Adin Scannell
Files removed from the working tree were not being properly removed from the branch, leading to symbol conflicts while building. This requires the change to 'git add --all' in the tools/go_branch.sh script. But why was this not caught by CI? The "git clean -f" command by default only cleans files in the current working directory. In order to clean the whole tree recursively, we need to specify a pathspec, which is ".". In addition to these fixes, re-add the "go tests" command to help prevent this from happening again, since merges on the Go branch will happen in GitHub actions for simplicity. The Go test is retained in BuildKite. PiperOrigin-RevId: 351503804
2021-01-12Drop TransportEndpointID from HandleControlPacketGhanan Gowripalan
When a control packet is delivered, it is delivered to a transport endpoint with a matching stack.TransportEndpointID so there is no need to pass the ID to the endpoint as it already knows its ID. PiperOrigin-RevId: 351497588

2021-01-11Fix Go branch for arm64.Adin Scannell
This requires several changes: * Templates must preserve relevant tags. * Pagetables templates are split into two targets, each preserving tags. * The binary VDSO is similarly split into two targets, with some juggling. * The top level tools/go_branch.sh now does a crossbuild of ARM64 as well, and checks and merges the results of the two branches together.
