Adam Langley 4702db6306 Update dummy PQ extension for round two. 
In this round, Google servers will echo the extension in order to test
the latency of both parties sending a PQ key-agreement message.

The extension is sent (and echoed) for both full and resumption
handshakes. This is intended to mirror the overhead of TLS 1.3 (even
when using TLS 1.2), as a resumption in TLS 1.3 still does a fresh key
agreement.

BoringSSL SSL Tests

This directory contains BoringSSL's protocol-level test suite.

Testing a TLS implementation can be difficult. We need to produce invalid but sufficiently correct handshakes to get our implementation close to its edge cases. TLS's cryptographic steps mean we cannot use a transcript and effectively need a TLS implementation on the other end. But we do not wish to litter BoringSSL with options for bugs to test against.

Instead, we use a fork of the Go crypto/tls package, heavily patched with configurable bugs. This code, along with a test suite and harness written in Go, lives in the runner directory. The harness runs BoringSSL via a C/C++ shim binary which lives in this directory. All communication with the shim binary occurs with command-line flags, sockets, and standard I/O.

This strategy also ensures we always test against a second implementation. All features should be implemented twice, once in C for BoringSSL and once in Go for testing. If possible, the Go code should be suitable for potentially upstreaming. However, sometimes test code has different needs. For example, our test DTLS code enforces strict ordering on sequence numbers and has controlled packet drop simulation.

To run the tests manually, run go test from the runner directory. It takes command-line flags found at the top of runner/runner.go. The -help option also works after using go test -c to make a runner.test binary first.

If adding a new test, these files may be a good starting point:

  • runner/runner.go: the test harness and all the individual tests.
  • runner/common.go: contains the Config and ProtocolBugs struct which control the Go TLS implementation's behavior.
  • test_config.h, test_config.cc: the command-line flags which control the shim's behavior.
  • bssl_shim.cc: the shim binary itself.

For porting the test suite to a different implementation see PORTING.md.
