Add required includes in tests and psa_crypto.c file in order to be able to compilef for the SPM solution.
Some functions needed to be deprecated from psa_crypto.c since they already implemented in the SPM.
Use PSA_BLOCK_CIPHER_BLOCK_SIZE() macro to get the cipher block size instead of accessing the operation struct
additionally, for SPM case, the 'block_size' member is not a member in the operation struct
In tests that had a hard-coded buffer size, use PSA_MAC_MAX_SIZE or
PSA_ASYMMETRIC_SIGNATURE_MAX_SIZE as appropriate.
Test that PSA_xxx_MAX_SIZE is larger than the size used in tests that
expect a specific output.
Make psa_export_key() always set a valid data_length when exporting,
even when there are errors. This makes the API easier to use for buggy
programs (like our test code).
Our test code previously used exported_length uninitialized when
checking to see that the buffer returned was all zero in import_export()
in the case where an error was returned from psa_export_key().
Initialize exported_length to an invalid length, and check that it gets
set properly by psa_export_key(), to avoid this using export_length
uninitialized. Note that the mem_is_zero() check is still valid when
psa_export_key() returns an error, e.g. where exported_length is 0, as
we want to check that nothing was written to the buffer on error.
Out test code also previous passed NULL for the data_length parameter of
psa_export_key() when it expected a failure (in key_policy_fail()).
However, data_length is not allowed to be NULL, especially now that we
write to data_length from psa_export_key() even when there are errors.
Update the test code to not pass in a NULL data_length.
It isn't used to define other macros and it doesn't seem that useful
for users. Remove it, we can reintroduce it if needed.
Define a similar function key_type_is_raw_bytes in the implementation
with a clear semantics: it's a key that's represented as a struct
raw_data.
In the test generate_random, focus on testing that psa_generate_random
is writing all the bytes of the output buffer and no more. Add a check
that it is writing to each byte of the output buffer. Do not try to
look for repeating output as the structure of a unit test isn't likely
to catch that sort of problem anyway.
Also add what was missing in the test suite to support block ciphers
with a block size that isn't 16.
Fix some buggy test data that passed only due to problems with DES
support in the product.
When psa_mac_start(), psa_encrypt_setup() or psa_cipher_setup()
failed, depending on when the failure happened, it was possible that
psa_mac_abort() or psa_cipher_abort() would crash because it would try
to call a free() function uninitialized data in the operation
structure. Refactor the functions so that they initialize the
operation structure before doing anything else.
Add non-regression tests and a few more positive and negative unit
tests for psa_mac_start() and psa_cipher_setup() (the latter via
psa_encrypt_setip()).
In psa_export_key, ensure that each byte of the output buffer either
contains its original value, is zero, or is part of the actual output.
Specifically, don't risk having partial output on error, and don't
leave extra data at the end of the buffer when exporting an asymmetric
key.
Test that exporting to a previously zeroed buffer leaves the buffer
zeroed outside the actual output if any.

This commit only moves test functions and test cases around. It does
not modify, add or remove tests.
Get rid of many redundant casts. In particular, it is not useful to
cast uint32_t values to size_t before performing arithmetic or
comparisons on them.
Rewrap a number of function calls, many of which now have narrower
arguments thanks to the removed casts. When a function call doesn't
fit on a single line, avoid grouping unrelated parameters together,
but do try to group a buffer pointer and the associated size.
Define more auxiliary variables xxx of a particular integer
type (psa_algorithm_t, psa_key_usage_t, etc.) corresponding to a test
function xxx_arg which has the type int. This avoids the need to cast
xxx_arg to an unsigned type sometimes in the code.
Avoid lines longer than 80 columns.
Remove some redundant parentheses, e.g. change
if( ( a == b ) && ( c == d ) )
to
if( a == b && c == d )
which makes lines less long and makes the remaining parentheses more
relevant.
Add missing parentheses around return statements.
There should be no semantic change in this commit.
Always adding things at the end tends to create merge conflicts.
Adding in the middle in this way makes the order more logical in
addition to avoiding conflicts.
