PR #3959 has proven that by adding a prefix
(LIBTESTDRIVER1/libtestdriver1_ in this commit) to
all MBEDTLS/PSA_* and mbedtls/psa_* symbols of a copy
of the Mbed TLS library, we can build a library that
can be linked with the Mbed TLS library.
This commit leverages this to build a PSA test driver
library based on the Mbed TLS library code.
The cryptographic features supported by the test
library are defined by:
. a minimal configuration (in the sense of config.h),
see config_test_driver.h
. PSA_WANT_* and PSA_ACCEL_* defined macros.
The PSA_WANT_* macros have to be the same as the ones
used to build the Mbed TLS library the test driver
library is supposed to be linked to as the PSA_WANT_*
macros are used in the definition of structures and
macros that are shared by the PSA crypto core,
Mbed TLS drivers and the driver test library.
The PSA_ACCEL_* macros are intended to define the
cryptographic features that have to be removed
from the Mbed TLS library and thus supported by the
test library in test scenarios. The PSA_ACCEL_* macros
to build the test library are thus mirrored from the
ones to build the Mbed TLS library by extended the
crypto_config.h: see
crypto_config_test_driver_entension.h.

At least twice, we added a classification flag but forgot to test it in the
relevant test functions. Add some protection so that this doesn't happen
again. In each classification category, put a macro xxx_FLAG_MASK_PLUS_ONE
at the end. In the corresponding test function, keep track of the flags that
are tested, and check that their mask is xxx_FLAG_MASK_PLUS_ONE - 1 which is
all the bits of the previous flags set.
Now, if we add a flag without testing it, the test
TEST_EQUAL( classification_flags_tested, xxx_FLAG_MASK_PLUS_ONE - 1 )
will fail. It will also fail if we make the set of flag numbers
non-consecutive, which is ok.
This reveals that three algorithm flags had been added but not tested (in
two separate occasions). Also, one key type flag that is no longer used by
the library was still defined but not tested, which is not a test gap but is
inconsistent. It's for DSA, which is relevant to the PSA encoding even if
Mbed TLS doesn't implement it, so keep the flag and do test it.

The status of signature wildcards with respect to PSA_ALG_IS_HASH_AND_SIGN
is unclear in the specification. A wildcard is usually instantiated with a
specific hash, making the implementation hash-and-sign, but it could also be
instantiated with a non-hash-and-sign algorithm. For the time being, go with
what's currently implemented, which is that they are considered
hash-and-sign.
Signed-off-by: Gilles Peskine <Gilles.Peskine@arm.com>
The current definition of PSA_ALG_IS_HASH_AND_SIGN includes
PSA_ALG_RSA_PKCS1V15_SIGN_RAW and PSA_ALG_ECDSA_ANY, which don't strictly
follow the hash-and-sign paradigm: the algorithm does not encode a hash
algorithm that is applied prior to the signature step. The definition in
fact encompasses what can be used with psa_sign_hash/psa_verify_hash, so
it's the correct definition for PSA_ALG_IS_SIGN_HASH. Therefore this commit
moves definition of PSA_ALG_IS_HASH_AND_SIGN to PSA_ALG_IS_SIGN_HASH, and
replace the definition of PSA_ALG_IS_HASH_AND_SIGN by a correct one (based
on PSA_ALG_IS_SIGN_HASH, excluding the algorithms where the pre-signature
step isn't to apply the hash encoded in the algorithm).
In the definition of PSA_ALG_SIGN_GET_HASH, keep the condition for a nonzero
output to be PSA_ALG_IS_HASH_AND_SIGN.
Everywhere else in the code base (definition of PSA_ALG_IS_SIGN_MESSAGE, and
every use of PSA_ALG_IS_HASH_AND_SIGN outside of crypto_values.h), we meant
PSA_ALG_IS_SIGN_HASH where we wrote PSA_ALG_IS_HASH_AND_SIGN, so do a
global replacement.

Set the build type to Release (-O2) when running CPU-intensive tests (ssl-opt,

when the main objective of the build is to check for build errors or warnings
and there aren't many tests to run; in this commit there are no such test
cases to change. Only use cmake with no build type (which results in not
passing a -O option, and thus missing some GCC warnings) when exercising cmake

* 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.

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).

Use case pattern matching instead of multiline split, given there is
only the well formatted PIDs to match on this should be safe.

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.

digits is also a local variable in host_test.function, leading to compilers
complaining about that shadowing the global variable in
test_suite_base64.function.

This is part of the definition of the encoding, not a choice of test
parameter, so keep it with the test code.
