This commit continues the introduction of the MD digest implementation
abstraction layer given by `mbedtls_md_handle_t` by adding getter
functions returning the various properties of an implementation
(e.g. name, digest type, digest size). For the existing implementation,
these are just structure field accesses; however, in configurations
hardcoding the choice of a fixed digest algorithm, we'll be able to
implement them as inline functions returning compile-time constants.
As has been previously done for ciphersuites, this commit introduces
a zero-cost abstraction layer around the type
mbedtls_md_info const *
whose valid values represent implementations of message digest algorithms.
Access to a particular digest implementation can be requested by name or
digest ID through the API mbedtls_md_info_from_xxx(), which either returns
a valid implementation or NULL, representing failure.
This commit replaces such uses of `mbedtls_md_info const *` by an abstract
type `mbedtls_md_handle_t` whose valid values represent digest implementations,
and which has a designated invalid value MBEDTLS_MD_INVALID_HANDLE.
The purpose of this abstraction layer is to pave the way for builds which
support precisely one digest algorithm. In this case, mbedtls_md_handle_t
can be implemented as a two-valued type, with one value representing the
invalid handle, and the unique valid value representing the unique enabled
digest.
Even though exhaustive testing of TinyCrypt is left for later,
without this test we don't have any evidence that PK writing
works for TinyCrypt-based PK context.
TinyCrypt only supports Secp256r1, so skip all tests in test_suite_x509parse
which use different curves, while splitting those which rely on Secp256r1
alone into two tests: one for legacy ECC, and one for TinyCrypt.
Studying and improving the TinyCrypt test coverage is left for a later commit.
The current pkwrite tests involving ECC all use curves different
from Secp256r1, so they don't apply to TinyCrypt.
Adding tests for TinyCrypt is left to a later commit.
- The underlying test vectors are for Secp192r1, while TinyCrypt uses Secp256r1.
- The test implementation is specific to the structure of legacy-ECC PK ctxs.
Addition of analogous tests for TinyCrypt-based ECC PK contexts are left
for a later commit.

Refactor receive_uint32()
Refactor get_byte function
Make the script portable to both pythons
Update the test encoding to support python3
update the test script
tests: Limit each log to 10 GiB
This test case was only executed if the SHA-512 module was enabled and
MBEDTLS_ENTROPY_FORCE_SHA256 was not enabled, so "config.pl full"
didn't have a chance to reach it even if that enabled
MBEDTLS_PLATFORM_NV_SEED_ALT.
Now all it takes to enable this test is MBEDTLS_PLATFORM_NV_SEED_ALT
and its requirements, and the near-ubiquitous MD module.
Call mbedtls_entropy_free on test failure.
Restore the previous NV seed functions which the call to
mbedtls_platform_set_nv_seed() changed. This didn't break anything,
but only because the NV seed functions used for these tests happened
to work for the tests that got executed later in the .data file.
memset has undefined behavior when either pointer can be NULL, which
is the case when it's the result of malloc/calloc with a size of 0.
The memset calls here are useless anyway since they come immediately
after calloc.
Call `greentea_getc()` 8 times, and then `unhexify` once, instead of
calling `receive_byte()`, which inside calls `greentea_getc()` twice,
for every hex digit.
Since Python3 handles encoding differently than Python2,
a change in the way the data is encoded and sent to the target is needed.
1. Change the test data to be sent as hex string
2. Convert the characters to binary bytes.
This is done because the mbed tools translate the encoding differently
(mbed-greentea, and mbed-htrunner)
If MBEDTLS_SSL_SINGLE_CIPHERSUITE is enabled, the type
mbedtls_ssl_ciphersuite_handle_t
is logically a boolean (concretely realized as `unsigned char`),
containing the invalid handle and the unique valid handle, which
represents the single enabled ciphersuite.
The SSL session structure mbedtls_ssl_session contains an instance
of mbedtls_ssl_ciphersuite_handle_t which is guaranteed to be valid,
and which is hence redundant in any two-valued implementation of
mbedtls_ssl_ciphersuite_handle_t.
This commit replaces read-uses of
mbedtls_ssl_session::ciphersuite_info
by a getter functions which, and defines this getter function
either by just reading the field from the session structure
(in case MBEDTLS_SSL_SINGLE_CIPHERSUITE is disabled), or by
returning the single valid ciphersuite handle (in case
MBEDTLS_SSL_SINGLE_CIPHERSUITE is enabled) and removing the
field from mbedtls_ssl_session in this case.

The previous tests used 100 parallel workers which for EC certificates
leads to a memory usage of more than 1Mb, hence leading to an out of memory
condition in tests using the memory buffer allocator which has a pool of 1Mb.
Use 25 workers but an increased number of iterations per worker instead.
This allows to build the library + tests via `make` without
specifying `PTHREAD=1`, in which case the X.509 threading
test suite will be silently dropped.
This is analogous to the pre-existing handling of the example
application `ssl_pthread_server`, which is only build if `PTHREAD=1`
and silently dropped otherwise.
This commit enhances the X.509 parsing test suite by a test
which exercises multiple threads concurrently verifying the
same certificate with the same set of trusted roots.
