Previously, we'd omitted OpenSSL's OCSP APIs because they depend on a complex OCSP mechanism and encourage the the unreliable server behavior that hampers using OCSP stapling to fix revocation today. (OCSP responses should not be fetched on-demand on a callback. They should be managed like other server credentials and refreshed eagerly, so temporary CA outage does not translate to loss of OCSP.) But most of the APIs are byte-oriented anyway, so they're easy to support. Intentionally omit the one that takes a bunch of OCSP_RESPIDs. The callback is benign on the client (an artifact of OpenSSL reading OCSP and verifying certificates in the wrong order). On the server, it encourages unreliability, but pyOpenSSL/cryptography.io depends on this. Dcument that this is only for compatibility with legacy software. Also tweak a few things for compatilibility. cryptography.io expects SSL_CTX_set_read_ahead to return something, SSL_get_server_tmp_key's signature was wrong, and cryptography.io tries to redefine SSL_get_server_tmp_key if SSL_CTRL_GET_SERVER_TMP_KEY is missing.

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 theConfigandProtocolBugsstruct 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.
