# 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.

# In the following tests, --recordsize is the value used by the G_NEXT_CLI (3.7.2) to configure the
# maximum record size using gnutls_record_set_max_size()
# (https://gnutls.org/reference/gnutls-gnutls.html#gnutls-record-set-max-size).
# There is currently a lower limit of 512, caused by gnutls_record_set_max_size()
# not respecting the "%ALLOW_SMALL_RECORDS" priority string and not using the
# more recent function gnutls_record_set_max_recv_size()
# (https://gnutls.org/reference/gnutls-gnutls.html#gnutls-record-set-max-recv-size).
# There is currently an upper limit of 4096, caused by the cli arg parser:
# https://gitlab.com/gnutls/gnutls/-/blob/3.7.2/src/cli-args.def#L395.
# Thus, these tests are currently limited to the value range 512-4096.
# Also, the value sent in the extension will be one larger than the value
# set at the command line:
# https://gitlab.com/gnutls/gnutls/-/blob/3.7.2/lib/ext/record_size_limit.c#L142

# Currently test certificates being used do not fit in 513 record size limit
# so for 513 record size limit tests we use preshared key to avoid sending
# the certificate.

# 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.

MAX_IM_CA='8'

# The tests for the max_int tests can pass with any number higher than MAX_IM_CA
# because only a chain of MAX_IM_CA length is tested. Equally, the max_int+1
# tests can pass with any number less than MAX_IM_CA. However, stricter preconditions

# The purpose of the next two tests is to test the client's behaviour when receiving a server

# 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.

# . 1.2/1.3 means that only TLS 1.2/TLS 1.3 is enabled.
# . 1.2+1.3 means that both TLS 1.2 and TLS 1.3 are enabled.
# . 1.2+(1.3)/(1.2)+1.3 means that TLS 1.2/1.3 is enabled and that
#   TLS 1.3/1.2 may be enabled or not.
# . max=1.2 means that both TLS 1.2 and TLS 1.3 are enabled at build time but
#   TLS 1.3 is disabled at runtime (maximum negotiable version is TLS 1.2).
# . min=1.3 means that both TLS 1.2 and TLS 1.3 are enabled at build time but
#   TLS 1.2 is disabled at runtime (minimum negotiable version is TLS 1.3).

# a TLS 1.3 and TLS 1.2 capable server is supposed to negotiate TLS 1.2 and
# to indicate in the ServerHello that it downgrades from TLS 1.3. The GnuTLS
# client then detects the downgrade indication and aborts the handshake even
# if TLS 1.2 was its preferred version. Keeping the test even if the
# handshake fails eventually as it exercices parts of the Mbed TLS

# The following test cases for restartable ECDH come in two variants:
# * The "(USE_PSA)" variant expects the current behavior, which is the behavior
#   from Mbed TLS 3.x when MBEDTLS_USE_PSA_CRYPTO is disabled. This tests
#   the partial implementation where ECDH in TLS is not actually restartable.
# * The "(no USE_PSA)" variant expects the desired behavior. These test
#   cases cannot currently pass because the implementation of restartable ECC
#   in TLS is partial: ECDH is not actually restartable. This is the behavior
#   from Mbed TLS 3.x when MBEDTLS_USE_PSA_CRYPTO is enabled.
#
# As part of resolving https://github.com/Mbed-TLS/mbedtls/issues/7294,
# we will remove the "(USE_PSA)" test cases and run the "(no USE_PSA)" test
# cases.

# With USE_PSA disabled we expect full restartable behaviour.

# Test server-initiated renegotiation with fragmented handshake on TLS1.2

# Note: The /reneg endpoint serves as a directive for OpenSSL's s_server
# to initiate a handshake renegotiation.
# Note: Adjusting the renegotiation delay beyond the library's default
# value of 16 is necessary. This parameter defines the maximum
# number of records received before renegotiation is completed.
# By fragmenting records and thereby increasing their quantity,
# the default threshold can be reached more quickly.
# Setting it to -1 disables that policy's enforment.
