- component_build_deprecated - chosen the refactored version from 2.16.6,
but with extra flags from baremetal.
- rest of the _no_xxx tests - merged make options to have PTHREAD=1 and
other changes from 2.16.6 (like -O1 instead of -O0).
- component_build_arm_none_eabi_gcc_no_64bit_multiplication - added
TINYCRYPT_BUILD=0 to the 2.16.6 version of make.

-Add config option for AES encyption only to config.h. Feature is
disabled by default.
-Enable AES encrypt only feature in baremetal.h configuration
-Remove AES encypt only feature from full config
- Do not include MBEDTLS_AES_ONLY_128_BIT_KEY_LENGTH to full config
as it requires also MBEDTLS_CTR_DRBG_USE_128_BIT_KEY
- Update check_config to check availability of flags:
MBEDTLS_AES_ONLY_128_BIT_KEY_LENGTH
MBEDTLS_CTR_DRBG_USE_128_BIT_KEY
This commit modifies the example programs ssl_client2 and ssl_server2
to allocate various structures on the heap instead of the stack. This
allows more fine-grained memory usage tracking via valgrind massif.
Use MBEDTLS_ENTROPY_HARDWARE_ALT instead of a new global RNG
flag. When this flag is enabled, the platform provides the RNG.
When running unit tests, rnd_std_rand should be used by overriding
the mbedtls_hardware_poll.
No effect for now, just declaring it here, implemented in subsequent commits.
The option requires MBEDTLS_USE_TINYCRYPT and is incompatible with
MBEDTLS_PK_RSA_ALT_SUPPORT and MBEDTLS_RSA_C.
Currently users (including the X.509 and SSL libraries) assume that if both PK
and RSA are enabled, then RSA is available through PK. If we allowed RSA to be
enabled together with PK_SINGLE_TYPE, we'd break that assumption. Going
through the code to find all place that rely on that assumption and fix them
would be cumbersome, and people who want PK_SINGLE_TYPE are unlikely to care
about RSA anyway, so let's just make them incompatible.
This is also consistent with what's done in the MD module: MD_SINGLE_HASH
requires that exactly one hash be enabled.
This commit introduces the configuration option
MBEDTLS_MD_SINGLE_HASH
which can be used to hardcode support for a single digest algorithm
at compile-time, at the benefit of reduced code-size.
To use, it needs to be defined to evaluate to a macro of the form
MBEDTLS_MD_INFO_{DIGEST}, and macros MBEDTLS_MD_INFO_{DIGEST}_FIELD
must be defined, giving rise to the various aspects (name, type,
size, ...) of the chosen digest algorithm. MBEDTLS_MD_INFO_SHA256
provides an example, but other algorithms can be added if needed.
At the moment, the effect of using MBEDTLS_MD_SINGLE_HASH is that
the implementation of the MD API (e.g. mbedtls_md_update()) need no
longer to through the abstraction of the mbedtls_md_info structures
by calling their corresponding function pointers fields (akin to
virtual functions in C++), but the directly call the corresponding
core digest function (such as mbedtls_sha256_update()).
Therefore, MBEDTLS_MD_SINGLE_HASH so far removes the second layer
of indirection in the chain
User calls MD API -> MD API calls underlying digest impl'n
-> Core digest impl'n does the actual work,
but the first indirection remains, as the MD API remains untouched
and cannot yet be inlined. Studying to what extend inlining the
shortened MD API implementations would lead to further code-savings
is left for a later commit.
TinyCrypt should be used as a replacement of legacy ECC. In particular,
there shouldn't be any use of identifiers from the legacy ECC module.
So far, there's the configuration option
MBEDTLS_SSL_CONF_SINGLE_EC_GRP_ID
that's relevant if MBEDTLS_SSL_CONF_SINGLE_CURVE is set, and which in
this case must resolve to an identifier of type mbedtls_ecp_group_id
indicating which single curve to enable.
With the introduction of TinyCrypt, we must either change the type
of this option to mbedtls_uecc_group_id, or introduce a separate
compilation option.
In order to avoid type confusion, this commit follows tha latter
approach, introducing the configuration option
MBEDTLS_SSL_CONF_SINGLE_UECC_GRP_ID
that indicatesthe TinyCrypt group identifier of the single curve
to use (must be Secp256r1) if MBEDTLS_SSL_CONF_SINGLE_CURVE
and MBEDTLS_USE_TINYCRYPT are set.
So far, ssl_client2 and ssl_server2 were relying on MBEDTLS_CTR_DRBG_C
being set. This commit adapts them to use HMAC DRBG in case CTR DRBG
is disabled in the configuration.
Note that disabling CTR DRBG in favor of HMAC DRBG can be useful on
constrained systems because Mbed TLS' HMAC DRBG is slightly smaller,
and moreover needed anyway as part of deterministic ECDSA.
Now function mbedtls_ssl_set_hostname is compile-time configurable
in config.h with define MBEDTLS_X509_REMOVE_HOSTNAME_VERIFICATION.
This affects to many x509 API's. See config.h for details.
This was found as a warning when running scripts/baremetal.sh --ram
--build-only manually, but it should have been found in a more automated way.
Adding -Werror so that future such issues will be caught by all.sh
(component_test_baremetal already invokes baremetal.sh --ram --build-only).
