In the test function for export_public_key, don't just check the
length of the result. Compare the actual result to the expected
result.
Take an extra argument that allows using an export buffer that's
larger or smaller than needed. Zero is the size given by
PSA_KEY_EXPORT_MAX_SIZE.
Don't check the output of psa_get_key_information. That's useful in
import_export because it tests both import and export, but not in
import_export_public_key whose goal is only to test public key export.
This commit adjusts the existing test data but does not add new test
cases.
snprintf was only added in Visual Studio 2015. This adds support
for building using Visual Studio versions prior to 2015.
This implementation of snprintf has been taken from platform.c
Wipe the whole MAC intermediate buffer, not just the requested MAC
size. With truncated MAC algorithms, the requested MAC size may be
smaller than what is written to the intermediate buffer.
Add comments noting that the maximum length of a MAC must fit in
PSA_ALG_MAC_TRUNCATION_MASK. Add a unit test that verifies that the
maximum MAC size fits.
Pass the nonce first, then the AD, then the input. This is the order
in which the data is processed and it's the order of the parameters to
the API functions.
There was a lot of repetition between psa_aead_encrypt and
psa_aead_decrypt. Refactor the code into a new function psa_aead_setup.
The new code should behave identically except that in some cases where
multiple error conditions apply, the code may now return a different
error code.
Internally, I rearranged some of the code:
* I removed a check that the key type was in CATEGORY_SYMMETRIC because
it's redundant with mbedtls_cipher_info_from_psa which enumerates
supported key types explicitly.
* The order of some validations is different to allow the split between
setup and data processing. The code now calls a more robust function
psa_aead_abort in case of any error after the early stage of the setup.
Exclude ".git" directories anywhere. This avoids spurious errors in git
checkouts that contain branch names that look like a file
check-files.py would check.
Exclude "mbed-os" anywhere and "examples" from the root. Switch to the
new mechanism to exclude "yotta/module". These are directories where
we store third-party files that do not need to match our preferences.
Exclude "cov-int" from the root. Fix#1691
We don't need to disable ASLR, so don't try. If gdb tries but fails,
the test runs normally, but all.sh then trips up because it sees
`warning: Error disabling address space randomization: Operation not permitted`
and interprets it as an error that indicates a test failure.
Even with a shallow clone of the repo where there are no tags available
to version with, don't error and instead show a unique abbreviated
commit hash as fallback.
Generate the documentation from include and doxygen/input only. Don't
get snared by files containing Doxygen comments that lie in other
directories such as tests, yotta, crypto/include, ...
The only difference this makes in a fresh checkout is that the
documentation no longer lists target_config.h. This file is from
yotta, does not contain any Doxygen comment, and its inclusion in the
rendered documentation was clearly an oversight.
This commit fixes some missing size comparison. In
aead_encrypt_decrypt, aead_encrypt and aead_decrypt, the test code
would not have noticed if the library function had reported an output
length that was not the expected length.
ASSERT_COMPARE tests that the two buffers have the same size and
content. The intended use is to replace TEST_ASSERT( size1 == size2 )
followed by memcmp on the content. Keep using memcmp when comparing
two buffers that have the same size by construction.
This commit resolves a bug whereby some test cases failed on systems
where mbedtls_calloc returns NULL when the size of 0, because the test
case asserted `pointer != NULL` regardless of the size.
The new macro ASSERT_ALLOC allocates memory with mbedtls_calloc and
fails the test if the allocation fails. It outputs a null pointer if
the requested size is 0. It is meant to replace existing calls to
mbedtls_calloc.
