Hanno Becker f765ce617f Remove ExtendedMS configuration API if hardcoded at compile-time
If the ExtendedMasterSecret extension is configured at compile-time
by setting MBEDTLS_SSL_CONF_EXTENDED_MASTER_SECRET and/or
MBEDTLS_SSL_CONF_ENFORCE_EXTENDED_MASTER_SECRET, the runtime
configuration APIs mbedtls_ssl_conf_extended_master_secret()
and mbedtls_ssl_conf_extended_master_secret_enforce() must
either be removed or modified to take no effect (or at most
check that the runtime value matches the hardcoded one, but
that would undermine the code-size benefits the hardcoding
is supposed to bring in the first place).

Previously, the API was kept but modified to have no effect.
While convenient for us because we don't have to adapt example
applications, this comes at the danger of users calling the runtime
configuration API, forgetting that the respective fields are
potentially already hardcoded at compile-time - and hence silently
using a configuration they don't intend to use.

This commit changes the approach to removing the configuration
API in case the respective field is hardcoded at compile-time,
and exemplifies it in the only case implemented so far, namely
the configuration of the ExtendedMasterSecret extension.

It adapts ssl_client2 and ssl_server2 by omitting the call to
the corresponding API if MBEDTLS_SSL_CONF_XXX are defined and
removing the command line parameters for the runtime configuration
of the ExtendedMasterSecret extension.

Manuel Pégourié-Gonnard c84511fb1f Add check for undocumented positive option 2019-06-18 10:32:25 +02:00
Manuel Pégourié-Gonnard ba8b1eb5d9 Use negated option for controlling TLS support.
A positive option looks better, but comes with the following compatibility
issue: people using a custom config.h that is not based on the default
config.h and need TLS support would need to manually change their config in
order to still get TLS.

Work around that by making the public option negative. Internally the positive
option is used, though.

In the future (when preparing the next major version), we might want to switch
back to a positive option as this would be more consistent with other options
we have.

Manuel Pégourié-Gonnard a771160799 Introduce new config.h flag for TLS
For now the option has no effect.

Adapted existing example config files. The fact that I needed to do this
highlights that this is a slightly incompatible change: existing users need to
update their existing custom configs (if standalone as opposed to based on the
default config) in order to still get the same behaviour.

The alternative would be to have a negative config option (eg NO_TLS or
DTLS_ONLY) but this doesn't fit as nicely with the existing options, so
hopefully the minor incompatibility is acceptable.

I don't think it's worth adding a new component to all.sh:
- builds with both DTLS and TLS are done in the default (and full) config
- TLS-only builds are done with eg config-suite-b.h in test-ref-configs
- a DTLS-only build is done with config-thread.h in test-ref-configs
- builds with none of them (and SSL_TLS_C enabled) are forbidden

Manuel Pégourié-Gonnard afdc1b5cbd Consistently use the name tinycrypt over uecc
We called in tinycrypt in the file names, but uecc in config.h, all.sh and
other places, which could be confusing. Just use tinycrypt everywhere because
that's the name of the project and repo where we took the files.

The changes were made using the following commands (with GNU sed and zsh):

sed -i 's/uecc/tinycrypt/g' **/*.[ch] tests/scripts/all.sh
sed -i 's/MBEDTLS_USE_UECC/MBEDTLS_USE_TINYCRYPT/g' **/*.[ch] tests/scripts/all.sh scripts/config.pl

temporarily fall back to the old, non-compliant implementation of the truncated
HMAC extension.

Andres Amaya Garcia 1e4ec667a4 Check time platform abstraction macro definitions (#534)
* Check time platform abstraction macro definitions

This patch adds some checks to check_config.h to ensure that macro
definitions for the time platform abstraction are acceptable. In this
case the requirements are:
  - MBEDTLS_PLATFORM_C and MBEDTLS_HAVE_TIME must be defined whenever
    MBEDTLS_PLATFORM_TIME_ALT, MBEDTLS_PLATFORM_TIME_TYPE_MACRO or
    MBEDTLS_PLATFORM_TIME_MACRO is defined.
  - MBEDTLS_PLATFORM_STD_TIME and MBEDTLS_PLATFORM_TIME_ALT cannot be
    defined simultaneously with MBEDTLS_PLATFORM_TIME_TYPE_MACRO or
    MBEDTLS_PLATFORM_TIME_MACRO.
  - MBEDTLS_HAVE_TIME and MBEDTLS_PLATFORM_TIME_ALT must be defined
    whenever MBEDTLS_PLATFORM_STD_TIME is defined.

* Document requirements for time abstraction macros

Document that time platform abstraction macros
MBEDTLS_PLATFORM_TIME_ALT, MBEDTLS_PLATFORM_TIME_MACRO,
MBEDTLS_PLATFORM_TIME_TYPE_MACRO and MBEDTLS_PLATFORM_STD_TIME require
MBEDTLS_HAVE_TIME to be defined in config.h.

* Fix requires comment in config.h

* Split preprocessor condition for simplicity
