Gilles Peskine 88e08464f5 Add dedicated test cases for psa_hash_compare
psa_hash_compare is tested for good cases and invalid-signature cases
in hash_compute_compare. Also test invalid-argument cases. Also run a
few autonomous test cases with valid arguments.

Gilles Peskine 06c28890c9 Add test function for effective key attributes
We're going to create some edge cases where the attributes of a key
are not bitwise identical to the attributes passed during creation.
Have a test function ready for that.

Gilles Peskine 841b14be02 Add tests of deprecated PSA macros
When MBEDTLS_TEST_DEPRECATED is defined, run some additional tests to
validate deprecated PSA macros. We don't need to test deprecated
features extensively, but we should at least ensure that they don't
break the build.

Add some code to component_build_deprecated in all.sh to run these
tests with MBEDTLS_DEPRECATED_WARNING enabled. The tests are also
executed when MBEDTLS_DEPRECATED_WARNING and
MBEDTLS_DEPRECATED_REMOVED are both disabled.

Gilles Peskine b8cde4ec03 Consolidate invalid-handle tests
Consolidate the invalid-handle tests from test_suite_psa_crypto and
test_suite_psa_crypto_slot_management. Start with the code in
test_suite_psa_crypto_slot_management and adapt it to test one invalid
handle value per run of the test function.

Gilles Peskine 1a2904c49a derive_input test function: Try output afterwards
After passing some inputs, try getting one byte of output, just to
check that this succeeds (for a valid sequence of inputs) or fails
with BAD_STATE (for an invalid sequence of inputs). Either output a
1-byte key or a 1-byte buffer depending on the test data.

The test data was expanded as follows:
* Output key type (or not a key): same as the SECRET input if success
  is expected, otherwise NONE.
* Expected status: PSA_SUCCESS after valid inputs, BAD_STATE after any
  invalid input.

Gilles Peskine 6842ba4d7a PSA crypto KDF: test bytes/key input independently of the step type
This commit only makes derive_input more flexible so that the key
derivation API can be tested with different key types and raw data for
each input step. The behavior of the test cases remains the same.

Gilles Peskine 5fe5e27591 Test slot_number attribute
Test the behavior of the getter/setter functions.

Test that psa_get_key_slot_number() reports a slot number for a key in
a secure element, and doesn't report a slot number for a key that is
not in a secure element.

Test that psa_get_key_slot_number() reports the correct slot number
for a key in a secure element.

Gilles Peskine bdc96fd636 Add tests to generate more random than MBEDTLS_CTR_DRBG_MAX_REQUEST
Add tests that call psa_generate_random() (possibly via
psa_generate_key()) with a size that's larger than
MBEDTLS_CTR_DRBG_MAX_REQUEST. This causes psa_generate_random() to
fail because it calls mbedtls_ctr_drbg_random() without taking the
maximum request size of CTR_DRBG into account.

Gilles Peskine 72c8c5b352 Merge remote-tracking branch 'upstream-crypto/development' into psa-api-1.0-beta-merge_development_20190801
Conflict resolution:
* `scripts/config.pl`:
  Take the exclusion of `MBEDTLS_PSA_CRYPTO_SE_C` from the API branch.
  Take the removal of `MBEDTLS_PSA_CRYPTO_STORAGE_ITS_C` (obsolete) from
  the development branch.
* `tests/scripts/all.sh`:
  Multiple instances of factoring a sequence of `config.pl` calls into
  a mere `config.pl baremetal` in the development branch, and a change in
  the composition of `baremetal` in the API branch. In each case, take the
  version from development.
* `tests/suites/test_suite_psa_crypto_slot_management.function`:
  A function became non-static in development and disappeared in the API
  branch. Keep the version from the API branch. Functions need to be
  non-static if they're defined but unused in some configurations,
  which is not the case for any function in this file at the moment.
* `tests/suites/test_suite_psa_crypto.function`:
  Consecutive changes in the two branches, reconciled.

Gilles Peskine c744d99386 Limit keys to 65528 bits
65528 bits is more than any reasonable key until we start supporting
post-quantum cryptography.

This limit is chosen to allow bit-sizes to be stored in 16 bits, with
65535 left to indicate an invalid value. It's a whole number of bytes,
which facilitates some calculations, in particular allowing a key of
exactly PSA_CRYPTO_MAX_STORAGE_SIZE to be created but not one bit
more.

As a resource usage limit, this is arguably too large, but that's out
of scope of the current commit.

Test that key import, generation and derivation reject overly large
sizes.

Gilles Peskine 7e0cff90b9 Move attribute fields to a substructure
Move the "core attributes" to a substructure of psa_key_attribute_t.
The motivation is to be able to use the new structure
psa_core_key_attributes_t internally.

variable warnings in some configurations.

Janos Follath 16de4a4017 Adapt the derive_setup tests to the new API
Part of the tests are adapted in this commit, another part is already
covered by the derive_input tests and some of them are not applicable to
the new API (the new API does not request capacity at the setup stage).

The test coverage temporarily drops with this commit, the two test cases
conserning capacity will be re-added in a later commit.

Janos Follath 71a4c9125b Add flag for removing deprecated API
Add the compile time option PSA_PRE_1_0_KEY_DERIVATION. If this is not
turned on, then the function `psa_key_derivation()` is removed.

Most of the tests regarding key derivation haven't been adapted to the
new API yet and some of them have only been adapted partially. When this
new option is turned off, the tests using the old API and test cases
using the old API of partially adapted tests are skipped.

The sole purpose of this option is to make the transition to the new API
smoother. Once the transition is complete it can and should be removed
along with the old API and its implementation.

Gilles Peskine 9e5bcbd8d1 Remove unused functions
These functions became obsolete when the key export format changed
from including the SubjectPublicKeyInfo to being just the key
material.

Gilles Peskine 1838e82190 Rename psa_helpers.function to psa_crypto_helpers.h
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.

Gilles Peskine 1153e7bd57 Replace all calls to mbedtls_psa_crypto_free by PSA_DONE
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.

Gilles Peskine 952f40962a Create PSA-specific helper function file
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.
