e6d0ac26ca mbedtls_test.py: Tell mypy to ignore mbed_host_tests
Since no typing stubs are available for mbed_host_tests.py, mypy
errors out on mbedtls_test.py with

    error: Skipping analyzing 'mbed_host_tests': found module but no type hints or library stubs

Ignore this import to get at least some benefit from mypy without
spending significant effort to write stubs.

c109b37b07 Test MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG
Add two builds with MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG to all.sh:
* full minus all DRBG (validates that PSA can work without any of the
  DRBG modules).
* with MBEDTLS_USE_PSA_CRYPTO and no CTR_DRBG (validates that PSA can
  work without CTR_DRBG, and that it works for USE_PSA_CRYPTO).

The goal is to exercise default/full, with/out USE_PSA_CRYPTO, and
with/out deterministic ECDSA (which requires HMAC_DRBG). The choice of
pairing is rather arbitrary.

c3623dbc76 State PSA_CRYPTO_KEY_ID_ENCODES_OWNER and USE_PSA_CRYPTO incompatibility
Code under MBEDTLS_USE_PSA_CRYPTO define is PSA client
code intended to use key identifiers of type psa_key_id_t.
Thus the MBEDTLS_PSA_CRYPTO_KEY_ID_ENCODES_OWNER
configuration option is incompatible with
MBEDTLS_USE_PSA_CRYPTO.

State this in config.h and check_config.h.

As a consequence:
. remove MBEDTLS_PSA_CRYPTO_KEY_ID_ENCODES_OWNER from
  the full configuration, as MBEDTLS_USE_PSA_CRYPTO is
  part of it.

. add a new component in all.sh to keep testing the
  library when MBEDTLS_PSA_CRYPTO_KEY_ID_ENCODES_OWNER
  is set.

d032195278 Phase 2 support for MBEDTLS_PSA_CRYPTO_CONFIG
This phase adds in support for the following features being
added to the list of features that can be configured in the
include/psa/crypto_config.h header file using the PSA_WANT_ALG_xxx
macros: ECDH, HMAC, HKDF, and RSA. These changes include changes to
the PSA crypto library to use the appropriate new guards that
will allow the feature to be compiled in or out either using
new PSA_WANT_ALG_xxx or the previous MBEDTLS_xxx macros.

For HKDF and HMAC, most of the PSA library code did not have a
specific matching MBEDTLS_xxx macro for that feature, but was instead
using the generic dependent MBEDTLS_MD_C macro. The ECDH and RSA
features more closely aligned with a direct replacement with a similar
macro.

The new tests for RSA, HMAC, and HKDF would normally unset additional
dependent macros, but when attempting to implement that level of
testing it required removal of too many core features like MD_C, PK_C,
ECP_C and other low level features. This may point to additional phases of
work to complete the transition of these features to the new model.

Updated the test_psa_want_ecdsa_disabled_software to enable and disable
the correct macros to accomplish the desired test. The previous version
left out the disabling of additional macros to ensure items related

of the accelerators MBEDTLS_PSA_ACCEL_ALG_ECDSA and DETERMINISTIC_ECDSA.

With the accelerators enabled the test portion had to be temporarily
disabled until the accelerator code is completed so the test will work
properly.

MBEDTLS_ECDSA_C is unset.

2ec2eaac31 Fix test issues with depends-hashes
Needed to make additional fixes so that when MBEDTLS_USE_PSA_CRYPTO
is defined, the depends-hashes test will succeed. There are two
versions of the ecdsa_verify_wrap() function, one with
MBEDTLS_USE_PSA_CRYPTO and when when it is not enabled. The non PSA
version is not using the md_alg parameter since it is not required.
The PSA version was using that parameter to derive a different value
it needed for PSA_ALG_ECDSA. The arguement of PSA_ALG_ECDSA is
ignored for psa_sign_hash and psa_verify_hash. It is present because
it is used and must be a valid hash, not zero, for psa_sign_hash
(but not psa_verify_hash) with PSA_ALG_DETERMINISTIC_ECDSA, and it is
needed for psa_sign_message and psa_verify_message which are not
implemented yet. The local parameter now uses PSA_ALG_ECDSA_ANY for
the verify function to avoid using the md_alg parameter and avoids
returning incorrect error codes.

231befab51 Fix printf escape errors in shell scripts
Fix `printf "$foo"` which treats the value of `foo` as a printf format

I used the following command to find potentially problematic lines:
```
git ls-files '*.sh' | xargs egrep 'printf +("?[^"]*|[^ ]*)\$'
```
The remaining ones are false positives for this regexp.

The errors only had minor consequences: the output of `ssl-opt.sh`
contained lines like
```
Renegotiation: gnutls server strict, client-initiated .................. ./tests/ssl-opt.sh: 741: printf: %S: invalid directive
PASS
```
and in case of failure the GnuTLS command containing a substring like
`--priority=NORMAL:%SAFE_RENEGOTIATION` was not included in the log
file. With the current tests, there was no risk of a test failure
going undetected.

d3beca9e38 Test Everest with only Curve25519 enabled
tests/scripts/curves.pl tests the library with a single curve enabled.
This uses the legacy ECDH context and the default ECDH implementation.
For Curve25519, there is an alternative implementation, which is
Everest. Test this. This also tests the new ECDH context, which
Everest requires.

a2611604d4 curves.pl: test with each elliptic curve enabled
Previously curves.pl tested with all elliptic curves enabled except
one, for each curve. This catches tests that are missing dependencies
on one of the curve that they use, but does not catch misplaced
conditional directives around parts of the library.

Now, we additionally test with a single curve, for each curve. This
catches missing or extraneous guards around code that is specific to
one particular curve or to a class of curves.

6240defd17 Add MBEDTLS_TEST_CONSTANT_FLOW_MEMSAN
This option allows to test the constant-flow nature of selected code, using
MemSan and the fundamental observation behind ctgrind that the set of
operations allowed on undefined memory by dynamic analysers is the same as the
set of operations allowed on secret data to avoid leaking it to a local
attacker via side channels, namely, any operation except branching and
dereferencing.

(This isn't the full story, as on some CPUs some instructions have variable
execution depending on the inputs, most notably division and on some cores
multiplication. However, testing that no branch or memory access depends on
secret data is already a good start.)

65a6fa3e26 Make cf_hmac() STATIC_TESTABLE
The test function now depends on MBEDTLS_TEST_HOOKS, which is enabled by
config.py full, and since there are already components in all.sh exercising
the full config, this test function is sill exercised even with this new
dependency.

Since this is the first time a test function depends on MBEDTLS_TEST_HOOKS,
fix a bug in check-names.sh that wasn't apparent so far: headers from
library/*.h were not considered when looking for macro definitions. This
became apparent because MBEDTLS_STATIC_TESTABLE is defined in library/common.h
and started being used in library/ssl_msg.c, so was flagged as a likely typo.

f1f180a6a1 all.sh: keep dd output in non-quiet mode
Since dd prints everything on stderr, both normal status update and actual
errors when they occur, redirecting that to /dev/null is a trade-off that's
acceptable in quiet mode (typically used on a developer's machine and the
developer will re-run in non-quiet mode if anything fails without sufficient
detail in the output), but not that much in non-quiet mode.

For example, if our dd invocation fails because the disk in full on a CI
machine, we want the error to be reported at the time we invoke dd, and not
later when a seemingly unrelated test fails due to an incorrect seedfile.

53fb66db12 Add support for RESTARTABLE with internal RNG
Currently we draw pseudo-random numbers at the beginning and end of the main
loop. With ECP_RESTARTABLE, it's possible that between those two occasions we
returned from the multiplication function, hence lost our internal DRBG
context that lives in this function's stack frame. This would result in the
same pseudo-random numbers being used for blinding in multiple places. While
it's not immediately clear that this would give rise to an attack, it's also
absolutely not clear that it doesn't. So let's avoid that by using a DRBG
context that lives inside the restart context and persists across
return/resume cycles. That way the RESTARTABLE case uses exactly the
same pseudo-random numbers as the non-restartable case.

Testing and compile-time options:

- The case ECP_RESTARTABLE && !ECP_NO_INTERNAL_RNG is already tested by
  component_test_no_use_psa_crypto_full_cmake_asan.
- The case ECP_RESTARTABLE && ECP_NO_INTERNAL_RNG didn't have a pre-existing
  test so a component is added.

Testing and runtime options: when ECP_RESTARTABLE is enabled, the test suites
already contain cases where restart happens and cases where it doesn't
(because the operation is short enough or because restart is disabled (NULL
restart context)).

2b2bdaa793 Add a --quiet option to all.sh
The primary purpose is to use it to run all.sh -k -q in the pre-push hook, but
this can be useful in any circumstance where you're not interested in the full
output from each component and just want a short summary of which components
were run (and if any failed).

Note that only stdout from components is suppressed, stderr is preserved so
that errors are reported. This means components should avoid printing to
stderr in normal usage (ie in the absence of errors).

Currently all the `check_*` components obey this convention except:
- check_generate_test_code: unittest prints progress to stderr
- check_test_cases: lots of non-fatal warnings printed to stderr

These components will be fixed in follow-up commits.
