Slightly simplify is_significantly_above_a_power_of_2() to make it
easier to understand:
* Remove the explicit negative answer for x <= 4. The only functional
difference this makes is that is_significantly_above_a_power_of_2(3)
is now true.
* Shift the most significant bit of x to position 8 rather than 15.

Add unit tests for mbedtls_mpi_fill_random() and mbedtls_mpi_random()
when the resulting MPI object previously had a nonzero value. I wrote
those to catch a bug that I introduced during the development of
mbedtls_mpi_random() (but does not appear in a committed version).
Signed-off-by: Gilles Peskine <Gilles.Peskine@arm.com>
mbedtls_mpi_random() uses mbedtls_mpi_cmp_mpi_ct(), which requires its
two arguments to have the same storage size. This was not the case
when the upper bound passed to mbedtls_mpi_random() had leading zero
limbs.
Fix this by forcing the result MPI to the desired size. Since this is
not what mbedtls_mpi_fill_random() does, don't call it from
mbedtls_mpi_random(), but instead call a new auxiliary function.
Add tests to cover this and other conditions with varying sizes for
the two arguments.

Rename mbedtls_ecp_gen_privkey_sw to mbedtls_mpi_random since it has
no particular connection to elliptic curves beyond the fact that its

The library rejected an RNG input of all-bits-zero, which led to the
key 2^{254} (for Curve25519) having a 31/32 chance of being generated
compared to other keys. This had no practical impact because the
probability of non-compliance was 2^{-256}, but needlessly
complicated the code.
The exception was added in 98e28a74e3 to
avoid the case where b - 1 wraps because b is 0. Instead, change the

The call to `tests/scripts/generate_psa_tests.py` added by the commit

In generate_psa_tests, use InputsForTest rather than PSAMacroCollector
to gather values. This way, the enumeration of values to test includes
values used in metadata tests in addition to constructors parsed from
header files. This allows greater coverage of values built from
constructors with arguments. This doesn't make a difference yet, but
it will once algorithm constructors with arguments are supported in
generate_psa_tests.
Make the injection of numerical values optional. They are useful for
test_psa_constant_names, so keep them there. Don't use them for
not-supported tests: they might make sense, but the current code
wouldn't work since it doesn't know how to make up fake key material
or what dependencies to generate. Don't use them for storage tests:
they only make sense for supported values.

On space-constrained platforms, it is a useful configuration to be able
to import/export and perform RSA key pair operations, but to exclude RSA
key generation, potentially saving flash space. It is not possible to
express this with the PSA_WANT_ configuration system at the present
time. However, in previous versions of Mbed TLS (v2.24.0 and earlier) it
was possible to configure a software PSA implementation which was
capable of making RSA signatures but not capable of generating RSA keys.
To do this, one unset MBEDTLS_GENPRIME.
Since the addition of MBEDTLS_PSA_BUILTIN_KEY_TYPE_RSA_KEY_PAIR, this
expressivity was lost. Expressing that you wanted to work with RSA key
pairs forced you to include the ability to generate key pairs as well.
Change psa_crypto_rsa.c to only call mbedtls_rsa_gen_key() if
MBEDTLS_GENPRIME is also set. This restores the configuration behavior
present in Mbed TLS v2.24.0 and earlier versions.
It left as a future exercise to add the ability to PSA to be able to
express a desire for a software or accelerator configuration that
includes RSA key pair operations, like signature, but excludes key pair
generation.
Without this change, linker errors will occur when attempts to call,
which doesn't exist when MBEDTLS_GENPRIME is unset.

For exporting keys, the test driver no longer reaches into the key

responsibility to be able to detect the key material it returned as part

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

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.

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.

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)).

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.

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.

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

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

This phase adds in support for the following features being
added to the list of features that can be configured in the

macros: ECDH, HMAC, HKDF, and RSA. These changes include changes to
the PSA crypto library to use the appropriate new guards that
will allow the feature to be compiled in or out either using
new PSA_WANT_ALG_xxx or the previous MBEDTLS_xxx macros.
For HKDF and HMAC, most of the PSA library code did not have a
specific matching MBEDTLS_xxx macro for that feature, but was instead
using the generic dependent MBEDTLS_MD_C macro. The ECDH and RSA
features more closely aligned with a direct replacement with a similar
macro.
The new tests for RSA, HMAC, and HKDF would normally unset additional
dependent macros, but when attempting to implement that level of
testing it required removal of too many core features like MD_C, PK_C,
ECP_C and other low level features. This may point to additional phases of
work to complete the transition of these features to the new model.

particular algorithm. For example, the algorithm is a based on block
cipher and requires a whole number of blocks, but the total input size
is not a multiple of the block size."
Currently, there is a distinction between encryption and decryption

The pk_ec_test_vec() was incorrectly using MBEDTLS_MD_SHA1 for the
parameter to mbedtls_pk_verify(). It should use MBEDTLS_MD_NONE since
that parameter is ignored for this test case.

Needed to make additional fixes so that when MBEDTLS_USE_PSA_CRYPTO
is defined, the depends-hashes test will succeed. There are two
versions of the ecdsa_verify_wrap() function, one with
MBEDTLS_USE_PSA_CRYPTO and when when it is not enabled. The non PSA
version is not using the md_alg parameter since it is not required.
The PSA version was using that parameter to derive a different value
it needed for PSA_ALG_ECDSA. The arguement of PSA_ALG_ECDSA is
ignored for psa_sign_hash and psa_verify_hash. It is present because
it is used and must be a valid hash, not zero, for psa_sign_hash
(but not psa_verify_hash) with PSA_ALG_DETERMINISTIC_ECDSA, and it is
needed for psa_sign_message and psa_verify_message which are not
implemented yet. The local parameter now uses PSA_ALG_ECDSA_ANY for
the verify function to avoid using the md_alg parameter and avoids
returning incorrect error codes.

With PSA crypto v1.0.0, a volatile key identifier may
contain a owner identifier but no file is associated
to it. Thus rename the type psa_key_file_id_t to
mbedtls_svc_key_id_t to avoid a direct link with a
file when a key identifier involves an owner
identifier.
The new type name is prefixed by mbedtls to highlight
that the type is specific to Mbed TLS implementation
and not defined in the PSA Cryptography API
specification.
The svc in the type name stands for service as this
is the key identifier type from the point of view of
the service providing the Cryptography services.
The service can be completely provided by the present
library or partially in case of a multi-client service.
As a consequence rename as well:
. MBEDTLS_PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER to
MBEDTLS_PSA_CRYPTO_KEY_ID_ENCODES_OWNER
. PSA_KEY_ID_INIT to MBEDTLS_SVC_KEY_ID_INIT
. PSA_KEY_FILE_GET_KEY_ID to MBEDTLS_SVC_KEY_ID_GET_KEY_ID
. psa_key_file_id_make to mbedtls_svc_key_id_make

Define always psa_key_id_t as defined in the PSA
Cryptography API specification independently of
whether the MBEDTLS_PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER

As a consequence, get rid of `psa_app_key_id_t` that is
not needed anymore.
Signed-off-by: Ronald Cron <ronald.cron@arm.com>
The purpose of this commit and the following is for
psa_key_id_t to always be as defined by the PSA
Cryptography API specification.
Currently psa_key_id_t departs from its specification
definition when MBEDTLS_PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER
configuration flag is set. In that configuration, it is set
to be equal to psa_key_file_id_t which in that configuration
encodes an owner identifier along the key identifier.
Type psa_key_file_id_t was meant to be the key identifier type
used throughout the library code. If
MBEDTLS_PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER is set it
includes both a key and owner identifier, otherwise it is
equal to psa_key_id_t.
It has not been the key identifier type throughout the
library so far because when the PSA Cryptography
specification was developped the library Doxygen
documentation was used to generate the PSA Cryptography API
specification thus the need to use psa_key_id_t and not
psa_key_file_id_t.
As this constraint does not hold anymore, move
to psa_key_file_id_t as the key identifier type throughout
the library code.
By the way, this commit updates the key identifier
initialization in the tests to be compatible with a
composit key identifier. A psa_key_id_make()
inline function is introduced to initialize key
identifiers (composit ot not) at runtime.

GCC up to 4.x defaults to C89. On our CI, we run the arm-none-eabi-gcc

If `$FILTER` (`-f`) and `$EXCLUDE` (`-e`) are simple selections that
can be expressed as shell patterns, use a case statement instead of
calling grep to determine whether a test case should be executed.
Using a case statement significantly reduces the time it takes to
determine that a test case is excluded (but the improvement is small
compared to running the test).
This noticeably speeds up running a single test or a small number of
tests. Before:
```
tests/ssl-opt.sh -f Default 1.75s user 0.54s system 79% cpu 2.885 total
```
After:
```
tests/ssl-opt.sh -f Default 0.37s user 0.14s system 29% cpu 1.715 total
```
There is no perceptible difference when running a large number of tests.

Avoid using the external command grep for simple string-based checks.
Prefer a case statement. This improves performance.
The performance improvement is moderate but noticeable when skipping
most tests. When a test is run, the cost of the associated grep calls
is negligible. In this commit, I focused on the uses of grep that can
be easily replaced and that are executed a large number of times.

Fix `printf "$foo"` which treats the value of `foo` as a printf format
rather than a string.
I used the following command to find potentially problematic lines:
```
git ls-files '*.sh' | xargs egrep 'printf +("?[^"]*|[^ ]*)\$'
```
The remaining ones are false positives for this regexp.
The errors only had minor consequences: the output of `ssl-opt.sh`
contained lines like
```
Renegotiation: gnutls server strict, client-initiated .................. ./tests/ssl-opt.sh: 741: printf: %S: invalid directive
PASS
```
and in case of failure the GnuTLS command containing a substring like
`--priority=NORMAL:%SAFE_RENEGOTIATION` was not included in the log
file. With the current tests, there was no risk of a test failure
going undetected.

Replace server2.crt with server2-sha256.crt which, as the name implies, is
just the SHA-256 version of the same certificate.
Replace server1.crt with cert_sha256.crt which, as the name doesn't imply, is
associated with the same key and just have a slightly different Subject Name,
which doesn't matter in this instance.
The other certificates used in this script (server5.crt and server6.crt) are
already signed with SHA-256.
This change is motivated by the fact that recent versions of GnuTLS (or older
versions with the Debian patches) reject SHA-1 in certificates by default, as
they should. There are options to still accept it (%VERIFY_ALLOW_BROKEN and
%VERIFY_ALLOW_SIGN_WITH_SHA1) but:
- they're not available in all versions that reject SHA-1-signed certs;
- moving to SHA-2 just seems cleaner anyway.

The documentation of mbedtls_pk_wrap_as_opaque is quite clear:
* \param handle Output: a PSA key handle.
* It's the caller's responsibility to call
* psa_destroy_key() on that handle after calling
* mbedtls_pk_free() on the PK context.
But the test failed to call psa_destroy_key().
While at it, also use PSA_DONE(): it ensures that if we fail to destroy the
key, we'll get an explicit error message about it without the need for
valgrind.
This is a preliminary to adding a valgrind-based test for constant-flow code:
we need to make sure the rest of the tests are fully valgrind-clean, which
