config-symmetric-only.h enables MBEDTLS_ENTROPY_NV_SEED so it needs a
seedfile. Create it in test-ref-configs.pl so that the script works on
its own, even if it is not invoked by all.sh.
Add a reference configuration with most symmetric cryptographic
algorithms enabled, but without any asymmetric cryptography. This
checks that we don't have spurious unexpected dependencies on
asymmetric-only modules such as bignum.
Keep HAVE_ASM disabled because it's platform-specific.
Keep HAVEGE disabled because it's untested and not recommended.
Keep MEMORY_BUFFER_ALLOC out because it isn't related to cryptography
at all and it makes memory sanitizers ineffective.
Keep THREADING disabled because it requires special build options.
mbedtls_ctr_drbg_seed() always set the entropy length to the default,
so a call to mbedtls_ctr_drbg_set_entropy_len() before seed() had no
effect. Change this to the more intuitive behavior that
set_entropy_len() sets the entropy length and seed() respects that and
only uses the default entropy length if there was no call to
set_entropy_len().
This removes the need for the test-only function
mbedtls_ctr_drbg_seed_entropy_len(). Just call
mbedtls_ctr_drbg_set_entropy_len() followed by
mbedtls_ctr_drbg_seed(), it works now.
Consolidate the invalid-handle tests from test_suite_psa_crypto and
test_suite_psa_crypto_slot_management. Start with the code in
test_suite_psa_crypto_slot_management and adapt it to test one invalid
handle value per run of the test function.
mbedtls_asn1_get_int() and mbedtls_asn1_get_mpi() behave differently
on negative INTEGERs (0200). Don't change the library behavior for now
because this might break interoperability in some applications. Change
the test function to the library behavior.
Fix the test data with negative INTEGERs. These test cases were
previously not run (they were introduced but deliberately deactivated
in 27d806fab41a11441d97017158fcb1356ef7e74f). The test data was
actually wrong: ASN.1 uses two's complement, which has no negative 0,
and some encodings were wrong. Now the tests have correct data, and
the test code rectifies the expected data to match the library
behavior.
mbedtls_asn1_get_int() and mbedtls_asn1_get_mpi() behave differently
on an empty INTEGER (0200). Don't change the library behavior for now
because this might break interoperability in some applications. Write
a test function that matches the library behavior.
When the asn1parse module is enabled but the bignum module is
disabled, the asn1parse test suite did not work. Fix this.
* Fix a syntax error in get_integer() (label immediately followed by a
closing brace).
* Fix an unused variable in get_integer().
* Fix `TEST_ASSERT( *p == q );` in nested_parse() failing because `*p`
was not set.
* Fix nested_parse() not outputting the length of what it parsed.
Add some ECDSA test cases where the hash is shorter or longer than the
key length, to check that the API doesn't enforce a relationship
between the two.
For the sign_deterministic tests, the keys are
tests/data_files/ec_256_prv.pem and tests/data_files/ec_384_prv.pem
and the signatures were obtained with Python Cryptodome:
from binascii import hexlify, unhexlify
from Crypto.Hash import SHA256, SHA384
from Crypto.PublicKey import ECC
from Crypto.Signature import DSS
k2 = ECC.import_key(unhexlify("3077020101042049c9a8c18c4b885638c431cf1df1c994131609b580d4fd43a0cab17db2f13eeea00a06082a8648ce3d030107a144034200047772656f814b399279d5e1f1781fac6f099a3c5ca1b0e35351834b08b65e0b572590cdaf8f769361bcf34acfc11e5e074e8426bdde04be6e653945449617de45"))
SHA384.new(b'hello').hexdigest()
hexlify(DSS.new(k2, 'deterministic-rfc6979').sign(SHA384.new(b'hello')))
k3 = ECC.import_key(unhexlify("3081a402010104303f5d8d9be280b5696cc5cc9f94cf8af7e6b61dd6592b2ab2b3a4c607450417ec327dcdcaed7c10053d719a0574f0a76aa00706052b81040022a16403620004d9c662b50ba29ca47990450e043aeaf4f0c69b15676d112f622a71c93059af999691c5680d2b44d111579db12f4a413a2ed5c45fcfb67b5b63e00b91ebe59d09a6b1ac2c0c4282aa12317ed5914f999bc488bb132e8342cc36f2ca5e3379c747"))
SHA256.new(b'hello').hexdigest()
hexlify(DSS.new(k3, 'deterministic-rfc6979').sign(SHA256.new(b'hello')))
There were tests to ensure that each entropy source reaches its
threshold, but no test that covers the total amount of entropy. Add
test cases with a known set of entropy sources and make sure that we
always gather at least MBEDTLS_ENTROPY_BLOCK_SIZE bytes from a strong
source.
Always pass a context object to entropy_dummy_source. This lets us
write tests that register more than one source and keep track of how
many times each one is called.

Add invasive checks that peek at the stored persistent data after some
successful import, generation or destruction operations and after
reinitialization to ensure that the persistent data in storage has the
expected content.
Add a parameter to the p_validate_slot_number method to allow the
driver to modify the persistent data.
With the current structure of the core, the persistent data is already
updated. All it took was adding a way to modify it.
When registering a key in a secure element, go through the transaction
mechanism. This makes the code simpler, at the expense of a few extra
storage operations. Given that registering a key is typically very
rare over the lifetime of a device, this is an acceptable loss.
Drivers must now have a p_validate_slot_number method, otherwise
registering a key is not possible. This reduces the risk that due to a
mistake during the integration of a device, an application might claim
a slot in a way that is not supported by the driver.
Since components run in the main process, unsetting
MBEDTLS_TEST_OUTCOME_FILE unset it in subsequent components as well.
To avoid this, save and restore the value.
(Making each component run in a subshell would be a better solution,
but it would be a much bigger change.)
Fix copypasta in some test cases with
MBEDTLS_TLS_DEFAULT_ALLOW_SHA1_IN_CERTIFICATES enabled.
Add unique suffix to the two
"DTLS fragmenting: proxy MTU: auto-reduction" test cases.
This is testing with $kex, not without $kex, so use $kex, not "-$kex".
In test-ref-configs.pl, use $conf rather than "$conf". This is purely
a matter of Perl coding style.
This script checks test case descriptions in test_suite_*.data and
ssl-opt.sh.
It reports the following issues:
* Error: forbidden character in a test case description.
* Error: Duplicate test description.
* Warning: Test description is too long.
