Test suite header code was not gaurded with test suite dependency.
But some test suites have additional code in the headers section.
Variables in that section become unused if suite functions are
gaurded. Hence gaurded the headers section.
But this changed cuased missing types in get_expression() function
that was originally accessing types defined through suite headers.
Hence had to gaurd expressions code as well.
Gaurding expressions does not allow parsing the parameters when
some types or hash defs are gaurded. Hence added function
check_test() to check if test is allowed or not before parsing the
parameters.
- Separate string and hex parameter as unhexify is moved out of the function. It's input should only be hex.
- Fix test mbedtls_ccm_encrypt_and_tag that grows input message buffer with tag
- Add missing expected length parameter in ECP TLS tests
- Add deleted TEST_ASSERT and mbedtls calls that got removed in script based code generation
New target gen-mbed-test generates mebdtls tests in mbed-os test format.
i.e. a dir tree like TESTS/<testgroup>/[<sub testgroup>/]<test case>.
The TESTS dir can then be imported into mbed-os to compile tests with mbed-os.
`mbedtls_ssl_get_record_expansion()` is supposed to return the maximum
difference between the size of a protected record and the size of the
encapsulated plaintext.
It had the following two bugs:
(1) It did not consider the new ChaChaPoly ciphersuites, returning
the error code #MBEDTLS_ERR_SSL_INTERNAL_ERROR in this case.
(2) It did not correctly estimate the maximum record expansion in case
of CBC ciphersuites in (D)TLS versions 1.1 and higher, in which
case the ciphertext is prefixed by an explicit IV.
This commit fixes both bugs.
In `mbedtls_ccm_self_test()`, enforce input and output
buffers sent to the ccm API to be contigous and aligned,
by copying the test vectors to buffers on the stack.
When MBEDTLS_ARC4_C and MBEDTLS_CIPHER_NULL_CIPHER were disabled, the stream
cipher function wasn't being include in the cipher struct, yet Chacha20 requires
it.
In ecp_mul_comb(), if (!p_eq_g && grp->T == NULL) and then ecp_precompute_comb() fails (which can
happen due to OOM), then the new array of points T will be leaked (as it's newly allocated, but
hasn't been asigned to grp->T yet).
Symptom was a memory leak in ECDHE key exchange under low memory conditions.
