Update the crypto submodule to the top of the Mbed Crypto development
branch. This brings in a version of Mbed Crypto that enables building
Mbed Crypto tests that depend on private headers, like
'psa_crypto_invasive.h'.
This also requires updating our config.h to include new configuration
options added to Mbed Crypto. MBEDTLS_PSA_ITS_FILE_C replaces
MBEDTLS_PSA_CRYPTO_STORAGE_FILE_C and MBEDTLS_PSA_CRYPTO_STORAGE_ITS_C.
MBEDTLS_PSA_INJECT_ENTROPY replaces MBEDTLS_PSA_HAS_ITS_IO.
Some tests use internal-only header files, which are stored in the
'library' folder, and therefore need the library folder passed in on the
include path. For non-submoudle builds, this is set globally in the
top-level CMakeLists.txt file. For submodule builds, this is set through
target includes to a path only meaningful when Mbed Crypto is built as a
submodule.
MBEDTLS_PSA_HAS_ITS_IO is not really useful since it doesn't actually
enable anything except the entropy seed file support, which only
requires the ITS interface and not a native implemetation. Remove it.
Since there is now a single storage backend, we don't need a backend
interface. Make the functions that were declared in
psa_crypto_storage_backend.h and are now both defined and used in
psa_crypto_storage.c static, except for psa_is_key_present_in_storage
which is used by the gray-box tests and is now declared in
psa_crypto_storage.h.
Since the ITS API has stabilized and we don't plan to make use of more
than ITS, we don't need an abstraction layer between key storage and
key storage over ITS. Merge the ITS code into the generic storage
module.
Now that we have ITS over files, we no longer need a direct backend
for key storage over files. Remove psa_crypto_storage_file and its
tests.
Switch MBEDTLS_PSA_CRYPTO_STORAGE_ITS_C and MBEDTLS_PSA_ITS_FILE_C on
by default. This preserves functionality and test coverage in the
default configuration, but forgets any key previously stored using the
file backend.
Merge storage_common.h and internal_trusted_storage.h into a single
file for convenience.
Remove #include of <psa/error.h> which crypto doesn't have yet and
include <psa/crypto_types.h> and <psa/crypto_values.h> instead.
Drop __cplusplus support which we don't need.
Tweak style (whitespace, line breaks, comment formatting) to satisfy
check-names.sh and check-files.sh.
Commit a72c10c44d5d54d05aceb00e0368f02f9f62151a in the
psa_trusted_storage_api repository, from which the PSA ITS
specification version 1.1 is derived.
Update the crypto submodule to the top of the Mbed Crypto development
branch. This brings in a version of Mbed Crypto compatible with being
tested using its tests (as it avoids adding duplicate and conflicting
CMake jobs).
Test the crypto implementation via tests from the Mbed Crypto submodule
instead of at the Mbed TLS top level.
The version test is the only test that is tested from both TLS and
Crypto, despite being entirely in libmbedcrypto. This is because the
test data is code-gen'd from the version updating script and the version
between Mbed TLS and Mbed Crypto don't necessarily always agree. The
test data must come from the top level module, as only the top level
module will have test data that matches the expected version.
For DH, ECC (Weierstrass curves) and DSA, specify that the re-drawing
method is the one defined by NIST as
"key-pair generation by testing candidates", and describe it
unambiguously.
Also specify DES explicitly.
Prepend ".crypto" to tests that came from the crypto submodule. This
allows, when this project is used as a submodule, for tests with names
the same between the parent and this project when used as a submodule to
both be built and run.
The version test suite is duplicated between Mbed TLS and Mbed Crypto.
Use TLS's copy and not Crypto's copy when Crypto is used as a submodule
of TLS.
The version test is the only test that is tested from both TLS and
Crypto, despite being entirely in libmbedcrypto. This is because the

test data must come from the top level module, as only the top level
module will have test data that matches the expected version.
For Makefiles, enable overriding where includes can come from in order
to enable the parent module to set the include path. This allows the
parent module to specify that its config.h should be used, even when the
submodule when built standalone would use a different config.h.
For CMake, always look in the parent's include folder and our own. List
the parent's include folder first, so that preference is given to parent
include files.
platform.h should only be used internally by the library implementation
itself, not the examples. Remove the dependency on platform.h from all
PSA programs.
As the SSL programs, like ssl_client2 and ssl_server2, are dependent on
SSL and therefore about to be removed, the only consumer of query_config
is the query_compile_time_config test. As such, it makes sense to move
query_config to be next to what uses it.
Doxygen will fail to build if we have references to files that don't
exist. Since we are planning on removing X.509 soon, we even need to
remove explicit Doxygen references to X.509 things as those will no
longer resolve once the X.509 files are deleted.
fixup! asn1: Remove dependency on X.509
There is some commented out X.509 certificate writing code present in
rsa_genkey. It looks like it has been commented out since the beginning
of time. Let's remove it, since commented out code is not in good style.
Our default configuration file, include/mbedtls/config.h, should always
match configs/config-psa-crypto.h. It had gotten out of sync, so put it
back into sync.
psa_generator_import_key() was only specified for "symmetric keys",
and there were some mistakes in the specification. Rewrite the
specification and extend it to other key types.
* For most private key types, specify that the function draws a byte
string repeatedly until the byte string is suitable.
* For DES, despite being a symmetric key type, re-drawing is
necessary.
* For Montgomery curves, despite being asymmetric, no re-drawing is
necessary.
* Specify the behavior for every standard key type other than RSA.
An implementation doesn't have to support all key types, but if it
does, it's better to have a standard.
