e1ee8f157c Test that SE driver persistent data is saved correctly
Add invasive checks that peek at the stored persistent data after some
successful import, generation or destruction operations and after
reinitialization to ensure that the persistent data in storage has the

5ec3a30edb SE driver: validate_slot_number: support changing persistent data
Add a parameter to the p_validate_slot_number method to allow the
driver to modify the persistent data.

With the current structure of the core, the persistent data is already
updated. All it took was adding a way to modify it.

3efcebbc5e SE support: Use a transaction when registering a key
When registering a key in a secure element, go through the transaction
mechanism. This makes the code simpler, at the expense of a few extra
storage operations. Given that registering a key is typically very
rare over the lifetime of a device, this is an acceptable loss.

Drivers must now have a p_validate_slot_number method, otherwise
registering a key is not possible. This reduces the risk that due to a
mistake during the integration of a device, an application might claim
a slot in a way that is not supported by the driver.

717cd76e8a Restore MBEDTLS_TEST_OUTCOME_FILE after test_default_out_of_box
Since components run in the main process, unsetting
MBEDTLS_TEST_OUTCOME_FILE unset it in subsequent components as well.
To avoid this, save and restore the value.

(Making each component run in a subshell would be a better solution,
but it would be a much bigger change.)

178c9aa966 Key derivation: forbid output_key without input_key
If none of the inputs to a key derivation is a
PSA_KEY_DERIVATION_INPUT_SECRET passed with
psa_key_derivation_input_key(), forbid
psa_key_derivation_output_key(). It usually doesn't make sense to
derive a key object if the secret isn't itself a proper key.

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.

224b0d656a Key derivation: allow both keys and direct inputs
Allow a direct input as the SECRET input step in a key derivation, in
addition to allowing DERIVE keys. This makes it easier for
applications to run a key derivation where the "secret" input is
obtained from somewhere else. This makes it possible for the "secret"
input to be empty (keys cannot be empty), which some protocols do (for
example the IV derivation in EAP-TLS).

Conversely, allow a RAW_DATA key as the INFO/LABEL/SALT/SEED input to a key
derivation, in addition to allowing direct inputs. This doesn't
improve security, but removes a step when a personalization parameter
is stored in the key store, and allows this personalization parameter
to remain opaque.

Add test cases that explore step/key-type-and-keyhood combinations.

6842ba4d7a PSA crypto KDF: test bytes/key input independently of the step type

31b0a3c351 Add a test component with malloc(0) returning NULL
Exercise the library functions with calloc returning NULL for a size
of 0. Make this a separate job with UBSan (and ASan) to detect
places where we try to dereference the result of calloc(0) or to do
things like

    buf = calloc(size, 1);
    if (buf == NULL && size != 0) return INSUFFICIENT_MEMORY;
    memcpy(buf, source, size);

which has undefined behavior when buf is NULL at the memcpy call even
if size is 0.

This is needed because other test components jobs either use the system
malloc which returns non-NULL on Linux and FreeBSD, or the
memory_buffer_alloc malloc which returns NULL but does not give as
useful feedback with ASan (because the whole heap is a single C
object).

efa2ac879d Uniquify test case descriptions
Make check-test-cases.py pass.

Prior to this commit, there were many repeated test descriptions, but
none with the same test data and dependencies and comments, as checked
with the following command:

    for x in tests/suites/*.data; do perl -00 -ne 'warn "$ARGV: $. = $seen{$_}\n" if $seen{$_}; $seen{$_}=$.' $x; done

Wherever a test suite contains multiple test cases with the exact same
description, add " [#1]", " [#2]", etc. to make the descriptions
unique. We don't currently use this particular arrangement of
punctuation, so all occurrences of " [#" were added by this script.

I used the following ad hoc code:

import sys

def fix_test_suite(data_file_name):
    in_paragraph = False
    total = {}
    index = {}
    lines = None
    with open(data_file_name) as data_file:
        lines = list(data_file.readlines())
        for line in lines:
            if line == '\n':
                in_paragraph = False
                continue
            if line.startswith('#'):
                continue
            if not in_paragraph:
                # This is a test case description line.
                total[line] = total.get(line, 0) + 1
                index[line] = 0
            in_paragraph = True
    with open(data_file_name, 'w') as data_file:
        for line in lines:
            if line in total and total[line] > 1:
                index[line] += 1
                line = '%s [#%d]\n' % (line[:-1], index[line])
            data_file.write(line)

44393c81aa psa_crypto: Add an ECDH+HKDF test with longer output
A test case for 32+0 was present three times, evidently overeager
copy-paste. Replace the duplicates by test cases that read more than
32 bytes, which exercises HKDF a little more (32 bytes is significant
because HKDF-SHA-256 produces output in blocks of 32 bytes).

I obtained the test data by running our implementation, because we're
confident in our implementation now thanks to other test cases: this
data is useful as a non-regression test.
