PSA_ALG_RSA_PSS algorithm now accepts only the same salt length for

Fixes#4946.
Signed-off-by: Gilles Peskine <Gilles.Peskine@arm.com>
Test the following combinations:
* 1024-bit key, SHA-256, salt=0
* 1024-bit key, SHA-256, salt=31 (1 byte shorter than standard)
* 1024-bit key, SHA-256, salt=32 (standard length)
* 1024-bit key, SHA-256, salt=94 (maximum possible length)
* 1024-bit key, SHA-512, salt=61 (1 byte shorter than standard)
* 1024-bit key, SHA-512, salt=62 (standard = maximum possible length)
* 528-bit key, SHA-512, salt=0 (only possible length)
Test psa_verify_hash() for both PSA_ALG_RSA_PSS and PSA_ALG_RSA_PSS_ANY_SALT
with all of these combinations. For psa_verify_message(), just test once
with the standard length and once with a different length.
Note that as of this commit, both PSA_ALG_RSA_PSS and
PSA_ALG_RSA_PSS_ANY_SALT accept any salt length during verification, hence
all the new test cases are positive.
The verify test cases were generated using the Python script below.

This is a variant of PSA_ALG_RSA_PSS which currently has exactly the same
behavior, but is intended to have a different behavior when verifying
signatures.
In a subsequent commit, PSA_ALG_RSA_PSS will change to requiring the salt
length to be what it would produce when signing, as is currently documented,
whereas PSA_ALG_RSA_PSS_ANY_SALT will retain the current behavior of
allowing any salt length (including 0).
Changes in this commit:
* New algorithm constructor PSA_ALG_RSA_PSS_ANY_SALT.
* New predicates PSA_ALG_IS_RSA_PSS_STANDARD_SALT (corresponding to
PSA_ALG_RSA_PSS) and PSA_ALG_IS_RSA_PSS_ANY_SALT (corresponding to
PSA_ALG_RSA_PSS_ANY_SALT).
* Support for the new predicates in macro_collector.py (needed for
generate_psa_constant_names).

On machines with more modern kernels (>5.4 from testing so far) the
useage of -b seems to conflict with the usage of -p. Whilst the usage of
-b seems like a good idea to avoid blocks as we are tight looping on it,
the usage of -p seems to require the usage of stat() (specifically in
/proc) which -b forbids. All you get is a load of warnings
(suppressable by -w) but never a positive result, which means that all
servers are reported as "Failed to start". We are not keen on losing
-b, so instead parse the output of lsof (using -F to format it) to
check the if PIDs that it outputs match that we are looking for.

A DES or AES block operation can fail in alternative implementations of

mbedtls_internal_aes_decrypt() (under MBEDTLS_AES_DECRYPT_ALT),
mbedtls_des_crypt_ecb() (under MBEDTLS_DES_CRYPT_ECB_ALT),
mbedtls_des3_crypt_ecb() (under MBEDTLS_DES3_CRYPT_ECB_ALT).
A failure can happen if the accelerator peripheral is in a bad state.
Several block modes were not catching the error.
This commit does the following code changes, grouped together to avoid
having an intermediate commit where the build fails:
* Add MBEDTLS_CHECK_RETURN to all functions returning int in aes.h and des.h.
* Fix all places where this causes a GCC warning, indicating that our code
was not properly checking the result of an AES operation:
* In library code: on failure, goto exit and return ret.
* In pkey programs: goto exit.
* In the benchmark program: exit (not ideal since there's no error
message, but it's what the code currently does for failures).
* In test code: TEST_ASSERT.
* Changelog entry.

Add test cases validating that if a stored key only had the hash policy,
then after loading it psa_get_key_attributes reports that it also has the
message policy, and the key can be used with message functions.

Negative x coordinate was tested with the value -1. It happens to be one
of the low order points both for Curve25519 and Curve448 and might be
rejected because of that and not because it is negative. Make sure that
x < 0 is the only plausible reason for the point to be rejected.

A test case for which the loop would take practically forever if it was
reached. The point would be to validate that the loop is not reached.
The test case should cause the CI to time out if starting with the
current code, ecp_check_pubkey_mx() was changed to call
ecp_check_pubkey_x25519() first and run the mbedtls_mpi_size(() test
afterwards, which would make no semantic difference in terms of memory
contents when the function returns, but would open the way for a DoS.

We were already rejecting them at the end, due to the fact that with the
usual (x, z) formulas they lead to the result (0, 0) so when we want to
normalize at the end, trying to compute the modular inverse of z will
give an error.
If we wanted to support those points, we'd a special case in
ecp_normalize_mxz(). But it's actually permitted by all sources
(RFC 7748 say we MAY reject 0 as a result) and recommended by some to
reject those points (either to ensure contributory behaviour, or to
protect against timing attack when the underlying field arithmetic is
not constant-time).
Since our field arithmetic is indeed not constant-time, let's reject
those points before they get mixed with sensitive data (in
ecp_mul_mxz()), in order to avoid exploitable leaks caused by the
special cases they would trigger. (See the "May the Fourth" paper

Backport 2.x: Fix and test the MBEDTLS_PSA_CRYPTO_SPM build
Straightforward backport from development to developement_2.x plus one trivial commit, only one approval is enough.
Modify tests to test mbedtls_psa_cipher_operation_t,
mbedtls_transparent_test_driver_cipher_operation_t and
mbedtls_opaque_test_driver_cipher_operation_t struct initialization macros.

Tests for psa_cipher_encrypt and psa_cipher_decrypt functions.
The psa_cipher_encrypt function takes no parameter for IV and always generates
it therefore there will be a randomness in the calculation and cannot be
validated by comparing the actual output with the expected output.
The function is tested by:
- doing a prtially randomized test with an encryption then a decryption
and validating the input with output of the decryption
- validating against the multipart encryption
The combination of this two methods provides enough coverage like a
known answer test.

Various functions for PSA hash operations call abort
on failure; test that this is done. The PSA spec does not require
this behaviour, but it makes our implementation more robust in
case the user does not abort the operation as required by the

The psa_verify_hash() is the pre-hashed version of the API and supposed
to work on hashes generated by the user. There were tests passing that
were getting "hashes" of sizes different from the expected.

Fix a bug introduced in "Fix multiplication producing a negative zero" that
caused the sign to be forced to +1 when A > 0, B < 0 and B's low-order limb
is 0.
Add a non-regression test. More generally, systematically test combinations
of leading zeros, trailing zeros and signs.

No need to bypass the API to fill limbs. It's a better test to just
set the top bit that we want to have set, and it's one less bypass of
the API.
