#
# Purpose
#
# Executes tests to prove various TLS/SSL options and extensions.
#
# The goal is not to cover every ciphersuite/version, but instead to cover
# specific options (max fragment length, truncated hmac, etc) or procedures
# (session resumption from cache or ticket, renego, etc).
#
# The tests assume a build with default options, with exceptions expressed
# with a dependency.  The tests focus on functionality and do not consider
# performance.

# The purpose of the next two tests is to test the client's behaviour when receiving a server
# certificate with an unsupported elliptic curve. This should usually not happen because
# the client informs the server about the supported curves - it does, though, in the
# corner case of a static ECDH suite, because the server doesn't check the curve on that
# occasion (to be fixed). If that bug's fixed, the test needs to be altered to use a
# different means to have the server ignoring the client's supported curve list.

## Bug report: https://github.com/openssl/openssl/issues/6902

# - MBEDTLS_SSL_DTLS_MAX_BUFFERING must be large enough to allow buffering
#   of the NewSessionTicket, but small enough to also allow buffering of
#   the encrypted Finished message.
# - The MTU setting on the server must be so small that the NewSessionTicket

# - All messages sent by the server must be small enough to be either sent
#   without fragmentation or be reassembled within the bounds of
#   MBEDTLS_SSL_DTLS_MAX_BUFFERING. Achieve this by testing with a PSK-based
#   handshake, omitting CRTs.
