The new PSA helper headers are needed at build time. When building
Mbed OS tests, the source files are copied to a directory under TESTS.
The required header files need to be present in this directory.
Create a new header file psa_helpers.h and put the one helper macro
that isn't specific to PSA crypto there. Use this header file in the
ITS test suite.
This file isn't like the other .function files: it isn't concatenated
by a separate preprocessing script, but included via C preprocessing.
Rename this file to .h. This isn't a normal C header, because it
defines auxiliary functions. But the functions aren't big and we only
have one compilation unit per executable, so this is good enough for
what we're doing.
Replace all calls to mbedtls_psa_crypto_free in tests by PSA_DONE.
This is correct for most tests, because most tests close open keys. A
few tests now fail; these tests need to be reviewed and switched back
to mbedtls_psa_crypto_free if they genuinely expected to end with some
slots still in use.
The new macro PSA_DONE calls mbedtls_psa_crypto_free, but before that,
it checks that no key slots are in use. The goal is to allow tests to
verify that functions like psa_close_key properly mark slots as
unused, and more generally to detect key slot leaks. We call
mbedtls_psa_crypto_free at the end of each test case, which could mask
a bug whereby slots are not freed when they should be, but their
content is correctly reclaimed by mbedtls_psa_crypto_free.
Create a specific file for helper functions that are related to the
PSA API. The reason for a separate file is so that it can include
<psa/crypto.h>, without forcing this header inclusion into every test
suite. In this commit, psa_helpers.function doesn't need psa/crypto.h
yet, but this will be the case in a subsequent commit.
Move PSA_ASSERT to psa_helpers.function, since that's the sort of
things it's for.
Include "psa_helpers.function" from the PSA crypto tests.
In the ITS test, don't include "psa_helpers". The ITS tests are
meant to stand alone from the rest of the library.
Now that psa_allocate_key() is no longer a public function, expose
psa_internal_allocate_key_slot() instead, which provides a pointer to
the slot to its caller.
Remove the key creation functions from before the attribute-based API,
i.e. the key creation functions that worked by allocating a slot, then
setting metadata through the handle and finally creating key material.
Use PEP 257 indented docstring style, mostly: always with """, with the
terminating """ on a separate line if the docstring is more than one
line, and with all lines indented to the opening """.
This commit does not change the text to keep the first paragraph single-line.
* Rename internal methods and fields to start with an underscore.
* Rename global constants to uppercase.
* Change methods that don't use self to be class methods or static
methods as appropriate.
No behavior change in this commit.

Modified on the development branch only to implement the enrollment
algorithm, which has been reimplemented on the API branch.
Keep the API branch.
Add parameters to psa_copy_key tests for the enrollment algorithm (alg2).
This commit only tests with alg2=0, which is equivalent to not setting
an enrollment algorithm.
Manually cherry-picked from ca5bed742f
by taking that patch, replacing KEYPAIR by KEY_PAIR
throughout (renaming applied in this branch), and discarding parts
about import_twice in test_suite_psa_crypto (this test function was
removed from this branch).
htmlpreview.github.io breaks some links: in index.html viewed through
this service, the links that should go to from_doxygen.html are shown
as internal links, so the meat of the document is invisible.
Link to Github pages instead. This relies on the documentation being
available on the `master` branch of the mbed-crypto repository.
This has the added benefit of not depending on a third-party service.
When running lcov, files can't be found relative to the parent project
(Mbed TLS) root. Use full, non-relative paths to refer to files used in
building Mbed Crypto from Mbed TLS in order to enable lcov to locate the
files properly.
