f9f7fdfe49 Rework MAC algorithm / key type validation
Reworked the validation of MAC algorithm with the used key type by
introducing psa_mac_key_can_do, which guarantees that PSA_MAC_LENGTH can
be called successfully after validation of the algorithm and key type.

This means psa_get_mac_output_length is no longer required.

6667a78c9b Add test for mbedtls_net_poll beyond FD_SETSIZE
mbedtls_net_poll() and mbedtls_net_recv_timeout() rely on select(),
which represents sets of file descriptors through the fd_set type.
This type cannot hold file descriptors larger than FD_SETSIZE. Make
sure that these functions identify this failure code.

Without a proper range check of the file descriptor in the
mbedtls_net_xxx function, this test fails when running with UBSan:
```
net_poll beyond FD_SETSIZE ........................................ source/library/net_sockets.c:482:9: runtime error: index 16 out of bounds for type '__fd_mask [16]'

c86a16548c Don't use STATIC_ASSERT_EXPR on non-GCC-compatible compilers
ARRAY_LENGTH has a portable but unsafe implementation, and a
non-portable implementation that causes a compile-time error if the
macro is accidentally used on a pointer.

The safety check was only implemented for __GCC__-defining compilers,
but the part that triggered the compile-time error was always used. It
turns out that this part triggers a build warning with MSVC (at least
with some versions: observed with Visual Studio 2013).
```
C:\builds\workspace\mbed-tls-pr-head_PR-4141-head\src\tests\src\psa_crypto_helpers.c(52): error C2220: warning treated as error - no 'object' file generated [C:\builds\workspace\mbed-tls-pr-head_PR-4141-head\src\mbedtls_test.vcxproj]
C:\builds\workspace\mbed-tls-pr-head_PR-4141-head\src\tests\src\psa_crypto_helpers.c(52): warning C4116: unnamed type definition in parentheses [C:\builds\workspace\mbed-tls-pr-head_PR-4141-head\src\mbedtls_test.vcxproj]
```

Since a compile-time error is never triggered when the compile-time
check for the argument type is not implemented, just use the unsafe
macro directly when there's no safety check.

2385f71abd Fix and simplify test assertions
mbedtls_test_fail does not copy the failure explanation string, so
passing a string on the stack doesn't work. This fixes a garbage
message that would appear if a test triggered a non-implemented code
path.

More generally, just use TEST_ASSERT instead of explicitly calling
mbedtls_test_fail, since we aren't playing any tricks with the error
location.

60b29fea46 Define WANT symbols for always-supported key types
PSA_KEY_TYPE_RAW_DATA and PSA_KEY_TYPE_DERIVE are always supported.
Make this explicit by declaring PSA_WANT_KEY_TYPE_RAW_DATA and
PSA_WANT_KEY_TYPE_DERIVE unconditionally. This makes it easier to
infer dependencies in a systematic way.

Don't generate not-supported test cases for those key types. They
would always be skipped, which is noise and would make it impossible
to eventually validate that all test cases pass in at least one
configuration over the whole CI.

Don't remove the exception in set_psa_test_dependencies.py for now, to
get less noise in dependencies. This may be revised later if it is
deemed more important to be systematic.

7d112ae04c Check in test_suite_psa_crypto_not_supported.generated.data
This test data file is automatically generated. We could do that as
part of the build, since the only requirement is Python and we have a
requirement on Python to build tests anyway (to generate the .c file
from the .function file). However, committing the generating file into
the repository has less impact on build scripts, and will be necessary
for some of the files generated by generate_psa_tests.py (at least the
storage format stability tests, for which stability is guaranteed by
the fact that the generated file doesn't change). To keep things
simple, for now, let's commit all the files generated by
generate_psa_tests.py into the repository.

14e428f921 Generate not-supported test cases automatically: import, generate
For each declared key type, generate test cases for psa_import_key and
psa_generate_key when the corresponding type is not supported.

Some special cases:
* Public keys can never be generated.
* Omit key types that Mbed TLS does not support at all.
* ECC and FFDH, which depend on a curve/group, are not covered yet.

The generated test cases are written to
tests/suites/test_suite_psa_crypto_not_supported.generated.data .

069346cdab New test suite for not-supported cases: key creation (import, generate)
To start with, test that key creation fails as intended when the key
type is not supported. This commit only covers psa_import_key and
psa_generate_key. A follow-up will cover psa_key_derivation_output_key.

My primary intent in creating this new test suite is to automatically
generate test cases by enumerating the key types and algorithms that
the library supports. But this commit only adds a few manually written
test cases, to get the ball rolling.

Move the relevant test cases of test_suite_psa_crypto.data that only
depend on generic knowledge about the API. Keep test cases that depend
more closely on the implementation, such as tests of non-supported key
sizes, in test_suite_psa_crypto.data.

b168c0d2e6 More robust code to set the IV
Check that the source address and the frame counter have the expected
length. Otherwise, if the test data was invalid, the test code could
build nonsensical inputs, potentially overflowing the iv buffer.

The primary benefit of this change is that it also silences a warning
from compiling with `gcc-10 -O3` (observed with GCC 10.2.0 on
Linux/amd64). GCC unrolled the loops and complained about a buffer
overflow with warnings like:
```
suites/test_suite_ccm.function: In function 'test_mbedtls_ccm_star_auth_decrypt':
suites/test_suite_ccm.function:271:15: error: writing 1 byte into a region of size 0 [-Werror=stringop-overflow=]
  271 |         iv[i] = source_address->x[i];
      |         ~~~~~~^~~~~~~~~~~~~~~~~~~~~~
suites/test_suite_ccm.function:254:19: note: at offset [13, 14] to object 'iv' with size 13 declared here
  254 |     unsigned char iv[13];
```
Just using memcpy instead of loops bypasses this warnings. The added
checks are a bonus.

9189202156 Remove trail check in the generate_random test
The test function generate_random allocated a few extra bytes after
the expected output and checked that these extra bytes were not
overwritten. Memory sanity checks such as AddressSanitizer and
Valgrind already detect this kind of buffer overflow, so having this
test in our code was actually redundant. Remove it.

This has the benefit of not triggering a build error with GCC
(observed with 7.5.0 and 9.3.0) when ASan+UBSan is enabled: with the
previous code using trail, GCC complained about an excessively large
value passed to calloc(), which was (size_t)(-sizeof(trail)).
Thus this commit fixes #4122.

2fa6b5f503 ECC import: more useful choice of INVALID_ARGUMENT vs NOT_SUPPORTED
Attempting to create an ECC key with a curve specification that is not
valid can plausibly fail with PSA_ERROR_INVALID_ARGUMENT ("this is not
a curve specification at all") or PSA_ERROR_NOT_SUPPORTED ("this may
be a curve specification, but not one I support"). The choice of error
is somewhat subjective.

Before this commit, due to happenstance in the implementation, an
attempt to use a curve that is declared in the PSA API but not
implemented in Mbed TLS returned PSA_ERROR_INVALID_ARGUMENT, whereas
an attempt to use a curve that Mbed TLS supports but for which support
was disabled at compile-time returned PSA_ERROR_NOT_SUPPORTED. This
inconsistency made it difficult to write negative tests that could
work whether the curve is implemented via Mbed TLS code or via a
driver.

After this commit, any attempt to use parameters that are not
recognized fails with NOT_SUPPORTED, whether a curve with the
specified size might plausibly exist or not, because "might plausibly
exist" is not something Mbed TLS can determine.

To keep returning INVALID_ARGUMENT when importing an ECC key with an
explicit "bits" attribute that is inconsistent with the size of the
key material, this commit changes the way mbedtls_ecc_group_of_psa()
works: it now works on a size in bits rather than bytes, with an extra
flag indicating whether the bit-size must be exact or not.

80eaa93b59 tests: psa: Reactivate and expand key management through test driver
The compilation guards in key_management.c are now
accelerator compilation guards (MBEDTLS_PSA_ACCEL_KEY_TYPE_xyz).

As a consequence when running the PSA driver wrapper
tests as part of test_psa_crypto_config_basic
and test_psa_crypto_drivers all.sh components all
key management cryptographic operations were handled by
the software builtin fallback, and not by the test driver
as intended in the first place.

This commits fixes this issue by:
. declaring an accelerator for ECC key pairs in
  test_psa_crypto_config_basic.
. declaring an accelerator for both ECC and RSA
  key pairs in test_psa_crypto_drivers.

It is possible to declare an accelerator for both
ECC and RSA key pairs in test_psa_crypto_drivers
and not in test_psa_crypto_config_basic because
in the case of test_psa_crypto_drivers the new
PSA configuration is not activated. That way,
the builtin fallback software implementation
is present to supply the transparent test driver
when some support is missing in it (mainly
RSA key generation).

Note that the declaration of accelerators does
much more than just "fixing" the execution flow of
driver wrapper tests, it makes all import and public
key export cryptographic operations in all unit
tests being handled by the transparent test driver
(provided that it supports the key type).

One test case related to key generation is
partially disabled. This will be fixed with the
rework of psa_generate_key along the lines
described in psa-crypto-implementation-structure.md.

72d8e0ad04 Key policy negative tests don't actually require the algorithm
It doesn't make much difference in practice, but to keep closer to
what the current code does, run negative key policy tests even if the
algorithm for the operation attempt is not supported.

In particular, this allows the following test cases to run:
* "PSA key policy: agreement + KDF, wrong agreement algorithm"
* "PSA key policy: raw agreement, wrong algorithm"
Without this exception, those two test cases would never run, because
they would depend on PSA_ALG_WANT_FFDH. Since FFDH is not implemented
yet, it isn't enabled in any configuration. There's no alternative to
FFDH for these particular test cases because ECDH is the only key
agreement that is implemented in Mbed TLS so far.

20987b9a46 Detect test cases that require something not to be supported
PSA_xxx_CATEGORY_yyy is used in metadata tests where it doesn't
involve any particular support, and elsewhere it's used as a value
that is definitely not supported but is in a plausible range. Such
symbols do not require any dependency.

If a test case is expects PSA_ERROR_NOT_SUPPORTED, its
dependencies (often including one negative dependency) cannot be
determined automatically, so leave that test case alone.

1af872d23b Move the fake PSA external RNG to its own header and source files
Move the declaration of the functions needed to use the test
implementation of mbedtls_psa_external_get_random() to a new header
file. Before, they were declared in
tests/include/test/psa_crypto_helpers.h, but this header file can't be
included in sample programs because it also includes headers from the
library directory which is not on the include path for sample
programs.

This fixes the build of the sample programs when
MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG and MBEDTLS_USE_PSA_CRYPTO are
enabled.

Move the implementation of the functions to a separate .c file as
well. This isn't strictly necessary, but makes the structure of the
source code easier to understand.

c85c20147b Don't call TEST_ASSERT in PSA_DONE
TEST_ASSERT jumps to the exit label, so it must not be called from
cleanup code executed after the exit label. It's legitimate (and
indeed very common) to call PSA_DONE in cleanup code, so PSA_DONE must
not jump to exit.

Define an auxiliary function test_fail_if_psa_leaking() that calls
test_fail() with the error message provided by
mbedtls_test_helper_is_psa_leaking(). This function currently needs to
be in helpers.function rather than in a PSA-specific helper file
because it calls test_fail which is defined in helpers.function.

d71539fd03 Fix test_psa_collect_statuses: update makefile dependencies
`tests/scripts/all.sh test_psa_collect_statuses` calls
`tests/scripts/psa_collect_statuses.py` which calls
`make -DRECORD_PSA_STATUS_COVERAGE_LOG` which must generate
`include/test/instrument_record_status.h`.
With the refactoring of `psa_crypto_helpers.{h,c}`, this now
needs to be done before building `psa_crypto_helpers.c`.

Also, remove `include/test/instrument_record_status.h` unconditionally
in `make clean`, which helps keep the build tree clean.

1e00565111 Refactor PSA test helpers: don't depend on test_info access
Refactor some PSA test helper functions and macros to avoid depending
on test_info and test_fail inside functions. These identifiers are
only defined in helpers.function, so they're only available in test
suites, and not in test helper modules (tests/src/*.c) which are also
linked into example programs.

This is in preparation for moving function definitions from
psa_crypto_helpers.h to psa_crypto_helpers.c.

No behavior change.

86cadb37d1 Remove now-redundant test result check
Since 349eadc58f, test_fail() reports
the first failure. So it's safe to call test_fail() again to report a
cleanup failure when we don't want to potentially erase information
about an earlier failure.

The behavior of mbedtls_test_helper_is_psa_pristine() changes if
test_info.result was neither TEST_RESULT_SUCCESS nor
TEST_RESULT_FAILED, but this should not matter since a skipped test
should not cause mbedtls_test_helper_is_psa_pristine() to fail.

The test suite assumed that if SHA512 was enabled, then

config MBEDTLS_SHA512_NO_SHA384 which allows precisely
to add SHA512 and not SHA384.

668a78d952 Added sppecific test cases for mbedtls_rsa_rsassa_pss_sign_ext()
- all positibe test cases were sampled from the CAVP test suite
  (SigGenPSS_186-2.txt, SigGenPSS_186-3.txt)
  Only kept one representative for each triple (modlen, sha, saltlen)
- two extra test cases were added to cover the maximum salt length
  (slen=olen-slen-2 and slen=(olen-slen-2)-1)
- in rsa.c, the salt intermediate buffer was too small to cover cases
  where slen > hlen. So reworked the code to generate the salt in the
  encoded message directly. This has the advantage to remove a memcpy
  and a memset.

557b8d663a Remove Extraneous bytes from buffer post pem write
In order to remove large buffers from the stack, the der data is written
into the same buffer that the pem is eventually written into, however
although the pem data is zero terminated, there is now data left in the
buffer after the zero termination, which can cause
mbedtls_x509_crt_parse to fail to parse the same buffer if passed back
in. Patches also applied to mbedtls_pk_write_pubkey_pem, and
mbedtls_pk_write_key_pem, which use similar methods of writing der data
to the same buffer, and tests modified to hopefully catch any future
regression on this.

taken when the exponent is large enough however, on builds where

In two test cases, the exponentiation computation was not being fully tested
as when A_bytes (the base) == N_bytes (the modulus) -> A = N. When this is the

know how many leading zeros it has because we know how the function
consumes bytes and when the test RNG produces null bytes.

Negative tests: test that if the RNG is willing to emit less than the
number of wanted bytes, the function fails.

80448aae2c Fix GCC warning about test_snprintf
GCC 11 generated the warnings because the parameter `ret_buf`
was declared as `const char[10]`, but some of the arguments
provided in `run_test_snprintf` are shorter literals, like "".

Now the type of `ret_buf` is `const char *`.
Both implementations of `test_snprintf` were fixed.

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.

3a4f0e3cc4 tests: psa: Reset key attributes where needed
After a call to psa_get_key_attributes() to retrieve
the attributes of a key into a psa_key_attributes_t
structure, a call to psa_reset_key_attributes() is
mandated to free the resources that may be
referenced by the psa_key_attributes_t structure.
Not calling psa_reset_key_attributes() may result in
a memory leak.

When a test function calls psa_get_key_parameters()
the associated key attributes are systematically
reset in the clean-up part of the function with a
comment to emphasize the need for the reset and make
it more visible.
