The new macro ASSERT_ALLOC_WEAK does not fail the test case if the
memory allocation fails. This is useful for tests that allocate a
large amount of memory, but that aren't useful on platforms where
allocating such a large amount is not possible.
Ideally this macro should mark the test as skipped. We don't yet have
a facility for that but we're working on it. Once we have a skip
functionality, this macro should be changed to use it.
Document how mbedtls_asn1_store_named_data allocates val.p in the new
or modified entry.
Change the behavior to be more regular, always setting the new length
to val_len. This does not affect the previous documented behavior
since this aspect was not documented. This does not affect current
usage in Mbed TLS's X.509 module where calls with the same OID always
use the same size for the associated value.
Use the test-many-sizes framework for string writes as
well (previously, it was only used for booleans and integers). This
way, more edge cases are tested with less test code.
This commit removes buffer overwrite checks. Instead of these checks,
run the test suite under a memory sanitizer (which we do in our CI).
Omit negative integers and MPIs that would result in values that look
like negative INTEGERs, since the library doesn't respect the
specifications there, but fixing it has a serious risk of breaking
interoperability when ASN.1 is used in X.509 and other
cryptography-related applications.
Add self-contained ASN.1 parsing tests, so that ASN.1 parsing is not
solely tested through X.509 and TLS.
The tests cover every function and almost complete line coverage in
asn1parse.c.
A few test cases containing negative and edge case INTEGER values are
deliberately deactivated because the historical library behavior is at
odds with official specifications, but changing the behavior might
break interoperability.
Other than that, these tests revealed a couple of minor bugs which
will be fixed in subsequent commits.
Document preconditions on parameters, values changed through pointers,
and error codes.
This commit leaves some issues regarding integers (especially negative
integers) open, because we don't have a policy decision on how to
handle them yet.
At the end of `psa_hmac_setup_internal()`, the ipad is cleared.
However, the size that was given to clear was `key_len` which is larger
than the size of `ipad`.
Add infrastructure to run unit tests and collect the return values for
every PSA API function that returns psa_status_t.

Previously, not all flags were supported by the gcc version that was used
(pre-4.9). Now, since the minimum version gcc version tested is 5.4,
the flags can be unified.
