fcb8711f6f Bump version to Mbed TLS 2.16.3 2019-09-06 13:27:00 +01:00
Teppo Järvelin
f69e641e03 Changed x509_internal.h methods as static.
Moved some functions under defined to get rid of compiler warnings.
Functions moved under defines:
 - mbedtls_x509_get_alg
 - mbedtls_x509_get_alg_null
 - mbedtls_x509_get_time
 - mbedtls_x509_get_ext
 - mbedtls_x509_sig_alg_gets
 - mbedtls_x509_key_size_helper

Left one function (mbedtls_x509_write_names) as non static as it increased code size.

8b3408f1a8 TinyCrypt Test: Run ssl-opt.sh without restrictions
Previously, the TinyCrypt component in all.sh restricted the ssl-opt.sh
to the 'Default, DTLS' test, due to implicit dependencies on Secp384r1.
These dependencies are now explicit and ssl-opt.sh skips corresponding
tests accordingly, so we can introduce a full run of ssl-opt.sh into
the TinyCrypt test in all.sh.

69c6cde728 ssl-opt.sh: Detect use of CRTs using Secp384R1 and potentially skip
This commit modifies ssl-opt.sh to autodetect the use of test certificates

tests if MBEDTLS_ECP_DP_SECP384R1_ENABLED isn't set.

4873fde059 TinyCrypt Test: Expand scope of compatibility testing for TinyCrypt
Previously, the TinyCrypt all.sh test restricted the run of compat.sh
to DTLS 1.2 and listed a few explicit ciphersuites.

This commit widens the scope of the test by testing any ciphersuite
based on ECDHE-ECDSA, regardless of TLS/DTLS or the particular version.

Further, it doesn't exclude SHA-384 as done previously.

7c2cd3e9d3 TinyCrypt Test: Force use of Secp256r1 CRTs and Keys in all.sh test
This commit uses the flexibility of being able to chose CRTs and keys
to be used by compat.sh through predefined environment variables to
force the use of Secp256r1 certificates and keys in the all.sh test
for TinyCrypt.

70c7373f81 compat.sh: Introduce env variable for CRTs, CAs and keys
This commit introduces environment variables

- SRV_ECDSA_CRT
- SRV_ECDSA_KEY
- CLI_ECDSA_CRT
- CLI_ECDSA_KEY
- SRV_RSA_CRT
- SRV_RSA_KEY
- CLI_RSA_CRT
- CLI_RSA_KEY
- CA_FILE

to tests/compat.sh which hold the path of the CA, client and server
certificate and key files to use by the script.

This is a preparatory step towards switching to a different set of
certificates and keys in case the configuration doesn't match the
certificates in use so far (e.g.: the ECDSA certificates use Secp384r1,
so if that's disabled, ECDSA tests will fail).

alone into two tests: one for legacy ECC, and one for TinyCrypt.

49ac40b81b Fixup: Don't reference legacy ECP curve identifier in config.h
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.

2e72dd8b9a ssl-opt.sh: Add var's of context s11n tests for ChaChaPoly,CCM,GCM
This commit splits each test in ssl-opt.sh related to context serialization
in three tests, exercising the use of CCM, GCM and ChaChaPoly separately.

The reason is that the choice of primitive affects the presence and size
of an explicit IV, and we should test that space for those IVs is correctly
restored during context deserialization; in fact, this was not the case
previously, as fixed in the last commit, and was not caught by the tests
because only ChaChaPoly was tested.

843f5bb06c ssl-opt.sh: Configure trusted CA explicitly
ssl_client2 and ssl_server2 either allow loading specific CRTs
and CAs from files, or to leave them unspecified, in which case
they're automatically picked from the test certificates.

The test certificates should be chosen in a way that when
not specifying any CRT or CA parameters, the automatically
chosen ones match - but if one of them is specified but not
the other, one should not expect tests to succeed.

With the recent switch to Secp256r1-based test certificates,
the default test certificates have changed, which breaks some
ssl-opt.sh tests which specify the server CRT explicitly but
not the client trusted CAs.

This commit fixes this by specifying the client's trusted CA
explicitly in accordance with the explicitly specified server CRT.

compat.sh used to skip OpenSSL altogether for DTLS 1.2, because older
versions of OpenSSL didn't support it. But these days it is supported.

We don't want to use DTLS 1.2 with OpenSSL unconditionally, because we
still use legacy versions of OpenSSL to test with legacy ciphers. So
check whether the version we're using supports it.

e03eb7bb64 Don't disallow 'record from another epoch' log msg in proxy ref test
It happens regularly in test runs that the server example application
shuts down a connection, goes into waiting mode for a new connection,
and then receives the encrypted ClosureAlert from the client. The only
reason why this does currently not trigger the 'record from another epoch'
message is that we handle ClientHello parsing outside of the main record
stack because we want to be able to detect SSLv2 ClientHellos. However,
this is likely to go away, and once it happens, we'll see the log message.
Further, when record checking is used, every record, including the mentioned
closure alert, is passed to the record checking API before being passed to
the rest of the stack, which leads to the log message being printed.

In summary, grepping for 'record from another epoch' is a fragile way
of checking whether a reordered message has arrived. A more reliable
way is to grep for 'Buffer record from epoch' which is printed when
a record from a future epoch is actually buffered, and 'ssl_buffer_message'
which is the function buffering a future handshake message.

af5d8abf26 Don't call memset on NULL pointer in NIST KW test suite
Note: There's no need to call `memset()` after `calloc()`
because `calloc()` includes zeroization.

756b3f2c25 entropy_nv_seed: cope with SHA-256
This test case was only executed if the SHA-512 module was enabled and
MBEDTLS_ENTROPY_FORCE_SHA256 was not enabled, so "config.pl full"
didn't have a chance to reach it even if that enabled
MBEDTLS_PLATFORM_NV_SEED_ALT.

Now all it takes to enable this test is MBEDTLS_PLATFORM_NV_SEED_ALT
and its requirements, and the near-ubiquitous MD module.

0450eecfae entropy_nv_seed: clean up properly
Call mbedtls_entropy_free on test failure.

Restore the previous NV seed functions which the call to
mbedtls_platform_set_nv_seed() changed. This didn't break anything,
but only because the NV seed functions used for these tests happened
to work for the tests that got executed later in the .data file.

fc41bd7f35 Don't call memset after calloc
memset has undefined behavior when either pointer can be NULL, which
is the case when it's the result of malloc/calloc with a size of 0.
The memset calls here are useless anyway since they come immediately
after calloc.

627fbee41a Don't offer SHA-1 in CertificateRequest message in TLS 1.2
mbedtls_ssL_set_calc_verify_md() is used to select valid hashes when
writing the server's CertificateRequest message, as well as to verify
and act on the client's choice when reading its CertificateVerify
message.

If enabled at compile-time and configured via mbedtls_ssl_conf_sig_hashes()
the current code also offers SHA-1 in TLS 1.2. However, the SHA-1-based
handshake transcript in TLS 1.2 is different from the SHA-1 handshake
transcript used in TLS < 1.2, and we only maintain the latter
(through ssl_update_checksum_md5sha1()), but not the former.
Concretely, this will lead to CertificateVerify verification failure
if the client picks SHA-1 for the CertificateVerify message in a TLS 1.2
handshake.

This commit removes SHA-1 from the list of supported hashes in
the CertificateRequest message, and adapts two tests in ssl-opt.sh
which expect SHA-1 to be listed in the CertificateRequest message.
