Gilles Peskine b13ed70b32 Check scripts/mbedtls_dev/*.py with pylint
mypy automatically checks the modules when it encounters them as
imports. Don't make it check them twice, because it would complain
about encountering them through different paths (via the command line
as scripts/mbedtls_dev/*.py and via imports as just mbedtls_dev/*.py).

Gilles Peskine 504c1a361e ssl_test_lib: move common functions and variables
Move from ssl_*2.c to ssl_test_lib.c:
* Functions that have exactly identical definitions in the two
  programs, and that don't reference the global variable opt which
  has a different type in the client and in the server. Also declare
  these functions in ssl_test_lib.h.

Move from ssl_*2.c to ssl_test_common_source.c:
* Functions that have exactly identical definitions in the two
  programs, but access fields of the global variable opt which
  has a different structure type in the client and in the server.
* The array ssl_sig_hashes_for_test, because its type is incomplete.

Gilles Peskine c11eb1fa07 Prepare to merge identical code from ssl_client2.c and ssl_server2.c
Adjust whitespace and comments in code of ssl_client2.c and
ssl_server2.c that was almost identical to make these chunks exactly
identical.

Make the common functions non-static.

This is in preparation for moving the common code to ssl_test_lib.c.

Move from ssl_*2.c to ssl_test_lib.h:

  server2 also had snprintf and the order and whitespace was slightly

Create a new source file for code that is shared between ssl_client2.c
and ssl_server2.c, but cannot be compiled separately and instead needs
to be #include'd in each program that uses it.

This is for code that references macros or types that are defined

Fredrik Strupe 462aa575a4 PSA Crypto: Don't skip key data removal when SE driver is not in use
Closing a wrapped key with the new SE driver interface while
MBEDTLS_PSA_CRYPTO_SE_C is also enabled leads to the key material not
being freed, even though an old SE driver is not in use, leading to a
memory leak. This is because a wrapped key is also considered external.

This commit extends the check for skipping by checking whether an
old-style SE driver is registered with the provided slot, in addition to
checking whether the key is external.

Initial revision.

Save-compare-load approach: the test case data contains attributes of
the object under test and the expected file content. Create the
object, save it, check that the file has the expected content, load
the file and check that the new object has the expected attributes.

Gilles Peskine 8814fc4a34 Make mbedtls_psa_get_random more usable outside psa_crypto.c
In the external RNG case, don't make mbedtls_psa_get_random() a
static inline function: this would likely result in identical
instances of this function in every module that uses it. Instead, make
it a single function with external linkage.

In the non-external case, instead of a trivial wrapper function, make
mbedtls_psa_get_random a constant pointer to whichever DRBG function
is being used.

Gilles Peskine 5894e8e7a4 Replace mbedtls_psa_random_state( ... ) by MBEDTLS_PSA_RANDOM_STATE
Hide the obtention of the pointer to the RNG state behind a macro.

To make it possible to use this macro in a module other than
psa_crypto.c, which will happen in the future, make sure that the
definition of the macro does not reference internal variables of
psa_crypto.c. For this purpose, in the internal-DRBG case, export a
symbol containing the address of the DRBG state.

When the RNG state is a pointer a DRBG state, just keep this pointer
in a variable: there's no need to store a pointer to a larger structure.
