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.

Gilles Peskine 73676cbc50 Put handle parameter last: psa_import_key
In psa_import_key, change the order of parameters to pass
the pointer where the newly created handle will be stored last.
This is consistent with most other library functions that put inputs
before outputs.

Gilles Peskine 2c2cf0e36d Update remaining test cases to use key attributes
Finish updating the tests to use psa_key_attributes_t and
psa_import_key instead of psa_key_policy_t and
psa_import_key_to_handle.

Gilles Peskine 87a5e565f4 Rename functions that inject key material to an allocated handle
This commit starts a migration to a new interface for key creation.
Today, the application allocates a handle, then fills its metadata,
and finally injects key material. The new interface fills metadata
into a temporary structure, and a handle is allocated at the same time
it gets filled with both metadata and key material.

This commit was obtained by moving the declaration of the old-style
functions to crypto_extra.h and renaming them with the to_handle
suffix, adding declarations for the new-style functions in crypto.h
under their new name, and running

    perl -i -pe 's/\bpsa_(import|copy|generator_import|generate)_key\b/$&_to_handle/g' library/*.c tests/suites/*.function programs/psa/*.c
    perl -i -pe 's/\bpsa_get_key_lifetime\b/$&_from_handle/g' library/*.c tests/suites/*.function programs/psa/*.c

Many functions that are specific to the old interface, and which will
not remain under the same name with the new interface, are still in
crypto.h for now.

All functional tests should still pass. The documentation may have
some broken links.

This commit is the result of the following command, followed by

Gilles Peskine 79e213cfc8 Don't include mbedtls/platform.h unconditionally
Programs must not include mbedtls/platform.h if MBEDTLS_PLATFORM_C is
not defined. Test suites don't need to include mbedtls/platform.h
because helpers.function takes care of it.

This commit also removes a stray `;` which is technically not standard C.

Gilles Peskine 9e1be6a246 Create the NV seed file for the tests if needed
Write an all-bits-zero NV seed file for the tests. Without this, if
the seed file is not present when this test suite is executed, the
PSA module initialization will fail, causing most test cases to fail.

Also write an all-bits-zero NV seed file at the end. The test cases in
this test suite mess with the file, but subsequent test suites may
need it.

Gilles Peskine 0fce4c5830 Add init tests with entropy from NV seed 2018-11-23 22:58:40 +01:00
Gilles Peskine 0b3b5733fc Support NV seed enabled at compile time but not at runtime
When testing with custom entropy sources, if MBEDTLS_ENTROPY_NV_SEED
is enabled at compile time but the NV seed source is not used at
runtime, mbedtls_entropy_func makes a second pass anyway. Cope with
this in the test code by telling the entropy module not to make this
second pass.

Gilles Peskine ebe770c693 Add tests with a fake entropy source
Add tests with a fake entropy source to check that the required amount
of entropy is one block, fed in one or more steps.

Gilles Peskine 5e76952235 Add a facility to configure entropy sources
Add a function to configure entropy sources. For testing only.

Use it to test that the library initialization fails properly if there is no
entropy source.

Gilles Peskine c6b6907066 Make library init and deinit more robust to errors
Allow mbedtls_psa_crypto_free to be called twice, or without a prior
call to psa_crypto_init. Keep track of the initialization state more
precisely in psa_crypto_init so that mbedtls_psa_crypto_free knows
what to do.
