dd544e1463 Fixed comments and test message output for new PSA tests
Provided a clearer comment for the description for ignoring
MBEDTLS_PSA_CRYPTO_CONFIG for full build setting.

Updated message output for test_psa_crypto_config_basic and
test_psa_want_ecdsa_disabled_software so it is more clear and
concise in what the test is doing. Removed inclusion of the
MBEDTLS_PSA_ACCEL_ALG_ECDSA since it should not have been used
for that particular tests.

5e940c6068 Fix additional data length field check for CCM
The CCM specification (NIST SP 800-38C) mandates that the formatting of
the additional data length l(a) changes when it is greater _or equal_ to
2^16 - 2^8 (>= 0xFF00). Since such lengths are not supported in mbed TLS,
the operation should fail in such cases.

This commit fixes an off-by-one error which allowed encryption/decryption
to be executed when l(a) was equal to 0xFF00, resulting in an
incorrect/non-standard length format being used.

Fixes #3719.

162a1104be Changes PSA key storage format to include key bits
* Stores bits in psa_persistent_key_storage_format.
* psa_load_persistent_key_into_slot still imports plaintext keys which
  ensures that the bits value gets set.
* Updates key specification to match new implementation.
* Expands persistent store and load tests with to check for bits
  attribute.
* Removes bits storage from psa_se_key_data_storage_t.

With the introduction of new tests for PSA crypto config features
the test needs to now be able to set and unset values from the

as a build arguement to modifying the header files using config.py.

f90e3019dd Use PSA_ERROR_INVALID_ARGUMENT for invalid cipher input sizes
... as opposed to PSA_ERROR_BAD_STATE.

The spec on psa_cipher_finish() states that PSA_ERROR_INVALID_ARGUMENT
should be returned when:

"The total input size passed to this operation is not valid for this
particular algorithm. For example, the algorithm is a based on block
cipher and requires a whole number of blocks, but the total input size
is not a multiple of the block size."

Currently, there is a distinction between encryption and decryption
on whether INVALID_ARGUMENT or BAD_STATE is returned, but this is not
a part of the spec.

This fix ensures that PSA_ERROR_INVALID_ARGUMENT is returned
consistently on invalid cipher input sizes.

The toplevel directory is actually just ../..: the makefile commands
are executed in the subdirectory. $(PWD) earlier was wrong because it
comes from the shell, not from make. Looking up $(MAKEFILE_LIST) is
wrong because it indicates where the makefile is (make -f), not which

70d7fb0c2d Don't hardcode TLS 1.3 labels in test cases
ssl_tls1_3_keys.c exports a structure containing all labels used
in the TLS 1.3 key schedule, but the TLS 1.3 key scheduling unit
tests so far replicated those labels in the test file. In particular,
wrong label values in ssl_tls1_3_keys.c wouldn't have been caught
by the unit tests.

This commit modifies the TLS 1.3 key schedule unit tests to use
the TLS 1.3 labels as exported by ssl_tls1_3_keys.c. This not only
makes sure that those labels are correct, but also avoids hardcoding
their hex-encoding in the test file.

2ec2eaac31 Fix test issues with depends-hashes
Needed to make additional fixes so that when MBEDTLS_USE_PSA_CRYPTO
is defined, the depends-hashes test will succeed. There are two
versions of the ecdsa_verify_wrap() function, one with
MBEDTLS_USE_PSA_CRYPTO and when when it is not enabled. The non PSA
version is not using the md_alg parameter since it is not required.
The PSA version was using that parameter to derive a different value
it needed for PSA_ALG_ECDSA. The arguement of PSA_ALG_ECDSA is
ignored for psa_sign_hash and psa_verify_hash. It is present because
it is used and must be a valid hash, not zero, for psa_sign_hash
(but not psa_verify_hash) with PSA_ALG_DETERMINISTIC_ECDSA, and it is
needed for psa_sign_message and psa_verify_message which are not
implemented yet. The local parameter now uses PSA_ALG_ECDSA_ANY for
the verify function to avoid using the md_alg parameter and avoids
returning incorrect error codes.

71016a9ea7 psa: Rename psa_key_file_id_t to mbedtls_svc_key_id_t
With PSA crypto v1.0.0, a volatile key identifier may
contain a owner identifier but no file is associated
to it. Thus rename the type psa_key_file_id_t to
mbedtls_svc_key_id_t to avoid a direct link with a
file when a key identifier involves an owner
identifier.

The new type name is prefixed by mbedtls to highlight
that the type is specific to Mbed TLS implementation
and not defined in the PSA Cryptography API
specification.

The svc in the type name stands for service as this
is the key identifier type from the point of view of
the service providing the Cryptography services.
The service can be completely provided by the present
library or partially in case of a multi-client service.

As a consequence rename as well:
. MBEDTLS_PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER to
  MBEDTLS_PSA_CRYPTO_KEY_ID_ENCODES_OWNER
. PSA_KEY_ID_INIT to MBEDTLS_SVC_KEY_ID_INIT

Cryptography API specification.

Currently psa_key_id_t departs from its specification
definition when MBEDTLS_PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER
configuration flag is set. In that configuration, it is set
to be equal to psa_key_file_id_t which in that configuration
encodes an owner identifier along the key identifier.

Type psa_key_file_id_t was meant to be the key identifier type
used throughout the library code. If
MBEDTLS_PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER is set it
includes both a key and owner identifier, otherwise it is
equal to psa_key_id_t.

It has not been the key identifier type throughout the
library so far because when the PSA Cryptography
specification was developped the library Doxygen
documentation was used to generate the PSA Cryptography API
specification thus the need to use psa_key_id_t and not
psa_key_file_id_t.

As this constraint does not hold anymore, move
to psa_key_file_id_t as the key identifier type throughout
the library code.

By the way, this commit updates the key identifier
initialization in the tests to be compatible with a
composit key identifier. A psa_key_id_make()
inline function is introduced to initialize key
identifiers (composit ot not) at runtime.

aeedd74b42 Pass -std=c99 to arm-none-eabi-gcc
GCC up to 4.x defaults to C89. On our CI, we run the arm-none-eabi-gcc
version from Ubuntu 16.04 on Travis, and that's 4.9, so the gcc-arm
builds started failing on Travis when we introduced a C99 construct in
the configurations that we test on arm on Travis. Other builds, and
Jenkins CI, are not affected because they use GCC 5.x or newer.

If test_fail is called multiple times in the same test case, report
the location of the first failure, not the last one.

With this change, you no longer need to take care in tests that use
auxiliary functions not to fail in the main function if the auxiliary
function has failed.

231befab51 Fix printf escape errors in shell scripts
Fix `printf "$foo"` which treats the value of `foo` as a printf format
rather than a string.

I used the following command to find potentially problematic lines:
```
git ls-files '*.sh' | xargs egrep 'printf +("?[^"]*|[^ ]*)\$'
```
The remaining ones are false positives for this regexp.

The errors only had minor consequences: the output of `ssl-opt.sh`
contained lines like
```
Renegotiation: gnutls server strict, client-initiated .................. ./tests/ssl-opt.sh: 741: printf: %S: invalid directive
PASS
```
and in case of failure the GnuTLS command containing a substring like
`--priority=NORMAL:%SAFE_RENEGOTIATION` was not included in the log
file. With the current tests, there was no risk of a test failure
going undetected.

An early draft of the PSA crypto specification required multipart

does not comply yet, and still allows the operation to keep going.

499bf4c0c8 compat.sh: quit using SHA-1 certificates
Replace server2.crt with server2-sha256.crt which, as the name implies, is
just the SHA-256 version of the same certificate.

Replace server1.crt with cert_sha256.crt which, as the name doesn't imply, is
associated with the same key and just have a slightly different Subject Name,
which doesn't matter in this instance.

The other certificates used in this script (server5.crt and server6.crt) are
already signed with SHA-256.

This change is motivated by the fact that recent versions of GnuTLS (or older
versions with the Debian patches) reject SHA-1 in certificates by default, as
they should. There are options to still accept it (%VERIFY_ALLOW_BROKEN and
%VERIFY_ALLOW_SIGN_WITH_SHA1) but:

- they're not available in all versions that reject SHA-1-signed certs;
- moving to SHA-2 just seems cleaner anyway.

feb0396d20 Fix memory leak in test_suite_x509write with PSA crypto
The documentation of mbedtls_pk_wrap_as_opaque is quite clear:

 * \param handle    Output: a PSA key handle.
 *                  It's the caller's responsibility to call
 *                  psa_destroy_key() on that handle after calling
 *                  mbedtls_pk_free() on the PK context.

But the test failed to call psa_destroy_key().

While at it, also use PSA_DONE(): it ensures that if we fail to destroy the
key, we'll get an explicit error message about it without the need for
valgrind.

This is a preliminary to adding a valgrind-based test for constant-flow code:
we need to make sure the rest of the tests are fully valgrind-clean, which
they weren't.

d4867877f1 Initialize key pointer in ecdh to NULL
Since it is being dereferenced by free on exit it should be inited to NULL.
Also added a small test that would trigger the issue.

3fa684ed91 Allow importing Montgomery public keys in PSA Crypto
PSA Crypto was checking the byte length of a to-be-imported public ECP key
against the expected length for Weierstrass keys, forgetting that
Curve25519/Curve448 exists.

d8902b6e3d tests: Replace "TEST_ASSERT(!memcmp ...)" by ASSERT_COMPARE
The usage of "!memcmp()" is at least not recommended
and better to use the macro dedicated for buffer
comparisons.

8779e9a70b Fix added proxy command when IPv6 is used
For explicit proxy commands (included with `-p "$P_PXY <args>` in the test
case), it's the test's writer responsibility to handle IPv6; only fix the
proxy command when we're auto-adding it.

e55653f085 Improve comments about padlen convention
The convention from the TLS RFC is a bit unusual, so even if the test
function's introductory comment mentions that we're taking the RFC's
definition, it doesn't hurt to repeat it in crucial places.

ca8287cbaf Use test_set_step() in loop in cf_hmac test
We only have a single integer available for two nested loops, but the loop
sizes are small enough compared to the integer's range that we can encode both
indexes. Since the integer is displayed in decimal in case of errors, use a
power of 10 to pack the two indexes together.

9670a59230 Start testing cf_hmac() for constant flow
Currently this breaks all.sh component test_memsan_constant_flow, just as
expected, as the current implementation is not constant flow.

This will be fixed in the next commit.

d3beca9e38 Test Everest with only Curve25519 enabled
tests/scripts/curves.pl tests the library with a single curve enabled.
This uses the legacy ECDH context and the default ECDH implementation.
For Curve25519, there is an alternative implementation, which is
Everest. Test this. This also tests the new ECDH context, which
Everest requires.

a2611604d4 curves.pl: test with each elliptic curve enabled
Previously curves.pl tested with all elliptic curves enabled except
one, for each curve. This catches tests that are missing dependencies
on one of the curve that they use, but does not catch misplaced
conditional directives around parts of the library.

Now, we additionally test with a single curve, for each curve. This
catches missing or extraneous guards around code that is specific to
one particular curve or to a class of curves.
