Although Coverity have now changed their URL to point at the new
project, they did not change the project name, it would seem.

Travis stopped being able to push builds to coverity due to the token
apparently being no longer valid. Rotating the token to see if that
fixes things.

Removes a case in mbedtls_asn1_named_data() where memcpy() could be
called with a null pointer and zero length. A test case is added for
this code path, to catch the undefined behavior when running tests with
UBSan.

These were a mistake when backporting the change from the development
branch, where mbedtls/config.h has been renamed to mbedtls/mbedtls_config.h.

This commit fixes#1992: The documentation of mbedtls_x509_crt_profile
previously stated that the bitfield `allowed_pks` defined which signature
algorithms shall be allowed in CRT chains. In actual fact, however,
the field also applies to guard the public key of the end entity
certificate.
This commit changes the documentation to state that `allowed_pks`
applies to the public keys of all CRTs in the provided chain.

Motivated by CVE-2022-21449, to which we're not vulnerable, but we
didn't have a test for it. Now we do.

MD2 and MD4 were declared as enabled (PSA_WANT_ALG_MD{2,4} defined) but not
actually implemented in the test driver (MBEDTLS_MD{2,4}_C) not defined. Fix
this inconsistency caued deterministic ECDSA tests using those hashes to
fail. Now MD2 and MD4 are consistently off and the offending test cases
don't run.

Validate the size macros directly from the output length in the test data,
rather than using the value returned by the library. This is equivalent
since the value returned by the library is checked to be identical.
Enforce that SIZE() <= MAX_SIZE(), in addition to length <= SIZE(). This is
stronger than the previous code which merely enforced length <= SIZE() and
length <= MAX_SIZE().

In PSA tests, don't try to exercise RC4 keys with other sizes. Do test that
attempts to use RC4 keys of other sizes fail with NOT_SUPPORTED (import does
work, which is not really useful, but removing import support would
technically break backward compatibility).

We test some configurations using drivers where the driver doesn't
support certain hash algorithms, but declares that it supports
compound algorithms that use those hashes. Until this is fixed,
in those configurations, don't try to actually perform operations.
The built-in implementation of asymmetric algorithms that use a
hash internally only dispatch to the internal md module, not to
PSA. Until this is supported, don't try to actually perform
operations when the operation is built-in and the hash isn't.

This both simplifies parsing a little, and suppresses warnings. Suppressing
warnings is both good and bad: on the one hand it resolves problems such as
https://github.com/Mbed-TLS/mbedtls/issues/5731, on the other hand it may
hide clues as to why lsof wouldn't be working as expected.

When ARC4 ciphersuites are compiled in, but removed from the default list,
requires_ciphersuite_enabled does not consider them to be enabled. Therefore
test cases for MBEDTLS_REMOVE_ARC4_CIPHERSUITES, which must run in such
configurations, must not use requires_ciphersuite_enabled.
Instead, require the corresponding cryptographic mechanisms. In addition,
for the test case "RC4: both enabled", bypass the automatic ciphersuite
support detection based on force_ciphersuite= that would otherwise cause
this test case to be skipped. (This automatic detection doesn't cause the
negative tests to be skipped because it has an exception whenthe handshake
is supposed to fail.)

`PSA_ALG_AEAD_WITH_SHORTENED_TAG(aead_alg, len) == aead_alg` when
`len == PSA_AEAD_TAG_LENGTH(aead_alg)`. So skip this case when testing
the printing of constants.
This fixes one test case due to the way arguments of
`PSA_ALG_AEAD_WITH_SHORTENED_TAG` are enumerated (all algorithms are tested
for a value of `len` which isn't problematic, and all values of `len` are
tested for one algorithm).

There's nothing wrong with ECC keys on Brainpool curves,
but operations with them are very slow. So we only exercise them
with a single algorithm, not with all possible hashes. We do
exercise other curves with all algorithms so test coverage is
perfectly adequate like this.

The PSA API does not use public key objects in key agreement
operations: it imports the public key as a formatted byte string.
So a public key object with a key agreement algorithm is not
a valid combination.

RSA-OAEP requires the key to be larger than a function of the hash size.
Ideally such combinations would be detected as a key/algorithm
incompatibility. However key/algorithm compatibility is currently tested
between the key type and the algorithm without considering the key size, and
this is inconvenient to change. So as a workaround, dispense
OAEP-with-too-small-hash from exercising, without including it in the
automatic operation-failure test generation.

Don't try to use {sign,verify}_message on algorithms that only support
{sign_verify}_hash. Normally exercise_key() tries all usage that is
supported by policy, however PSA_KEY_USAGE_{SIGN,VERIFY}_MESSAGE is implied
by PSA_KEY_USAGE_{SIGN,VERIFY}_HASH so it's impossible for the test data to
omit the _MESSAGE policies with hash-only algorithms.

Don't re-code the logic to determine a valid nonce length.
This fixes exercise_key() for PSA_ALG_CHACHA20_POLY1305, which was trying to
