Hanno Becker 938f9e9bdb Undo deprecation of MBEDTLS_ERR_CAMELLIA_INVALID_INPUT_LENGTH
Merging MBEDTLS_ERR_CAMELLIA_INVALID_INPUT_LENGTH and
MBEDTLS_ERR_CAMELLIA_INVALID_KEY_LENGTH is an API break.

Hanno Becker 9dbefa1793 Fix conflict between constant deprecation and check-names.sh
The previous introduction of constant deprecation macros
in platform_util.h lead to failure of tests/scrips/check-names.sh
because the regular expressions in the latter choked on the brackets
in the part `__attribute__((deprecated))` of the definition of the
helper type `mbedtls_deprecated_{numeric|string}_constant_t`.

Postponing any further study and potential robustness improvements
in check-names.sh to another time, this commit circumvents this
problem by temporarily abbreviating  `__attribute__((deprecated))`
as `MBEDTLS_DEPRECATED`, which doesn't lead to problems with
check-names.sh.

Hanno Becker 6d0816a8ae Introduce macros to deprecate constants in the API
This commit introduces macros

* MBEDTLS_DEPRECATED_STRING_CONSTANT
* MBEDTLS_DEPRECATED_NUMERIC_CONSTANT

to platform_util.h which can be used to deprecate public macro constants.

Their definition is essentially taken from dhm.h where the
MBEDTLS_DEPRECATED_STRING_CONSTANT was used to deprecate
insecure hardcoded DHM primes.

Gilles Peskine 23fd2bdb94 Update some documentation related to key slots
Some of the documentation is obsolete in its reference to key slots
when it should discuss key handles. This may require a further pass,
possibly with some reorganization of error codes.

Update the documentation of functions that modify key slots (key
material creation and psa_set_key_policy()) to discuss how they affect
storage.

Gilles Peskine 79a11d6c42 Test invalid lifetime regardless of support for persistent keys

psa_create_key must fail if invoked with an invalid lifetime value.

Gilles Peskine 09829036ab Document some functions in internal headers 2018-12-11 16:48:14 +01:00
Gilles Peskine fa4135b135 Move more slot management functions to the proper module
Move psa_load_persistent_key_into_slot,
psa_internal_make_key_persistent and psa_internal_release_key_slot to
the slot management module.

Expose psa_import_key_into_slot from the core.

After this commit, there are no longer any functions declared in
psa_crypto_slot_management.h and defined in psa_crypto.c. There are
still function calls in both directions between psa_crypto.c and
psa_crypto_slot_management.c.
2018-12-11 16:48:14 +01:00
Gilles Peskine 66fb126e87 Move the key slot array to the slot management module
Move the key slot array and its initialization and wiping to the slot
management module.

Also move the lowest-level key slot access function psa_get_key_slot
and the auxiliary function for slot allocation
psa_internal_allocate_key_slot to the slot management module.

Gilles Peskine 408319be3a Remove redundant check for slot->allocated

slots was removed.

Gilles Peskine 039b90cf5b Expose the PSA key slot structure to internal modules
Move psa_key_slot_t to a new header psa_crypto_core.h, to prepare for
moving the responsibility for some fields to
psa_crypto_slot_management.c.

Gilles Peskine 3f10812ff9 Use the library-wide zeroize function
Since Mbed TLS 2.10, there is a single copy of
mbedtls_platform_zeroize for the whole library instead of one per
module. Update the PSA crypto module accordingly.

Gilles Peskine 2f060a8ea5 Rename key_slot_t to psa_key_slot_t in psa_crypto.c
That way it'll be ok to add it to an internal header so as to use it
in multiple source modules.

Gilles Peskine 4a044739a8 Fix the build without persistent storage
Add missing guards on MBEDTLS_PSA_CRYPTO_STORAGE_C.

NOT_SUPPORTED.
2018-12-11 16:48:14 +01:00
Gilles Peskine c5487a8892 Drop support for psa_key_slot_t in psa_crypto.c
This commit finishes the removal of support for direct access to key
slots in psa_crypto.c.

This marks the end of the necessary phase of the transition to key
handles. The code should subsequently be refactored to move key slot
management from psa_crypto.c to psa_crypto_slot_management.c.
2018-12-11 16:48:13 +01:00
Gilles Peskine b77a6b25c0 Remove psa_set_key_lifetime
This function is no longer relevant. Use psa_create_key instead.
2018-12-11 16:48:13 +01:00
Gilles Peskine f6cc435a8a Remove psa_key_slot_t from public headers
This commit marks the beginning of the removal of support for direct
access to key slots. From this commit on, programs that use
psa_key_slot_t will no longer compile.

Subsequent commits will remove the now-unused legacy support in
psa_crypto.c.

Gilles Peskine 7bc9f68232 Convert the PSA crypto persistent storage tests to the new handle API
Switch from the direct use of slot numbers to handles allocated by
psa_allocate_key.

The general principle for each function is:
* Change `psa_key_slot_t slot` to `psa_key_handle_t handle` or
  `psa_key_id_t key_id` depending on whether it's used as a handle to
  an open slot or as a persistent name for a key.
* Call psa_create_key() before using a slot, instead of calling
  psa_set_key_lifetime to make a slot persistent.

Remove the unit test persistent_key_is_configurable which is no longer
relevant.

Gilles Peskine a23eafce3a Fix snprintf call to assume less about integral type sizes
The code only worked if psa_key_id_t (formerly psa_key_slot_t)
promoted to int and every value fit in int. Now the code only assumes
that psa_key_id_t is less wide than unsigned long, which is the case
since psa_key_id_t is a 32-bit type in our implementation.
2018-12-11 16:48:13 +01:00
Gilles Peskine 8d4919bc6a Persistent storage implementation: psa_key_slot_t -> psa_key_id_t
Move the persistent storage implementation from psa_key_slot_t to
psa_key_id_t. For the most part, this just means changing the types of
function arguments.

Update the documentation of some functions to reflect the fact that
the slot identifier is purely a storage identifier and is not related
to how the slot is designated in memory.

Gilles Peskine b0edfb513b Convert the PSA example programs to the new handle API
Switch from the direct use of slot numbers to handles allocated by
psa_allocate_key.
2018-12-11 16:48:13 +01:00
Gilles Peskine bdf309ccdb Convert the PSA crypto cryptography tests to the new handle API
Switch from the direct use of slot numbers to handles allocated by
psa_allocate_key.

This commit does not affect persistent key tests except for the one
test function in test_suite_psa_crypto that uses persistent keys
(persistent_key_load_key_from_storage).

The general principle for each function is:
* Change `psa_key_slot_t slot` to `psa_key_handle_t handle`.
* Call psa_allocate_key() before setting the policy of the slot,
  or before creating key material in functions that don't set a policy.
* Some PSA_ERROR_EMPTY_SLOT errors become PSA_ERROR_INVALID_HANDLE
  because there is now a distinction between not having a valid
  handle, and having a valid handle to a slot that doesn't contain key
  material.
* In tests that use symmetric keys, calculate the max_bits parameters
  of psa_allocate_key() from the key data size. In tests where the key
  may be asymmetric, call an auxiliary macro KEY_BITS_FROM_DATA which
  returns an overapproximation. There's no good way to find a good
  value for max_bits with the API, I think the API should be tweaked.

Gilles Peskine a8860b2990 Remove lifetime test functions
With the handle-based slot management interface, psa_set_key_lifetime
will no longer exist, so remove the corresponding unit tests.
2018-12-11 16:48:13 +01:00
Gilles Peskine dc911fd594 Remove redundant slot-based test
fill_slots is superseded by many_transient_handles.
2018-12-11 16:48:13 +01:00
Gilles Peskine f77ed1f20b Factor the common idiom psa_wipe_key_slot into a function
Many places in the code called psa_remove_key_data_from_memory (which
preserves metadata for the sake of failues in psa_import_key) followed
by clearing the slot data. Use an auxiliary function for this.
