This finishes getting rid of ssl_read_bytes! Now we have separate entry-points for the various cases. For now, I've kept TLS handshake consuming records partially. When we do the BIO-less API, I expect that will need to change, since we won't have the record buffer available. (Instead, the ssl3_read_handshake_bytes and extend_handshake_buffer pair will look more like the DTLS side or Go and pull the entire record into init_buf.) This change opts to make read_app_data drive the message to completion in anticipation of DTLS 1.3. That hasn't been specified, but NewSessionTicket certainly will exist. Knowing that DTLS necessarily has interleave seems something better suited for the SSL_PROTOCOL_METHOD internals to drive. It needs refining, but SSL_PROTOCOL_METHOD is now actually a half-decent abstraction boundary between the higher-level protocol logic and DTLS/TLS-specific record-layer and message dispatchy bits.

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.
