Gilles Peskine 09c0a2364b mbedtls_asn1_store_named_data: clarify val allocation behavior
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.

Gilles Peskine 3f37dca794 asn1write: Test short and large buffers more systematically
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).

Gilles Peskine 105031b1e1 asn1_write documentation: say that integers must be non-negative
The documentation never said it explicitly, but the ASN.1 library
doesn't support negative integers. Say it explicitly.

Also fix a copypasta error.

Gilles Peskine 1dbab67ce8 Improve mbedtls_asn1_write_int to support values >255
mbedtls_asn1_write_int had an undocumented restriction to values that
fit in a single octet. Fix this.

Negative integers are still not supported.

Gilles Peskine 3a032c36c1 Add test cases for BOOLEANs and INTEGERs
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.

Gilles Peskine f7d6acd475 mbedtls_asn1_get_int: allow leading zeros properly
Allow any number of leading zeros, not just based on sizeof(int).

Gilles Peskine 27d806fab4 Add ASN.1 parsing tests
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.

Gilles Peskine bcbe1dfb23 Improve the documentation of ASN.1 parsing functions
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.

Ron Eldor 296eca6e76 Fix a buffer overflow in hmac_setup_internal
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`.

Hanno Becker 2fcdd7446e Fix a memory leak in x509write test suite
This leak wasn't discovered by the CI because the only test in
all.sh exercising the respective path enabled the custom memory
buffer allocator implementations of calloc() and free(), hence
bypassing ASan.

This commit adds a build as well as runs of `make test` and
