Gilles Peskine 72c8c5b352 Merge remote-tracking branch 'upstream-crypto/development' into psa-api-1.0-beta-merge_development_20190801
Conflict resolution:
* `scripts/config.pl`:
  Take the exclusion of `MBEDTLS_PSA_CRYPTO_SE_C` from the API branch.
  Take the removal of `MBEDTLS_PSA_CRYPTO_STORAGE_ITS_C` (obsolete) from
  the development branch.
* `tests/scripts/all.sh`:
  Multiple instances of factoring a sequence of `config.pl` calls into
  a mere `config.pl baremetal` in the development branch, and a change in
  the composition of `baremetal` in the API branch. In each case, take the
  version from development.
* `tests/suites/test_suite_psa_crypto_slot_management.function`:
  A function became non-static in development and disappeared in the API
  branch. Keep the version from the API branch. Functions need to be
  non-static if they're defined but unused in some configurations,
  which is not the case for any function in this file at the moment.
* `tests/suites/test_suite_psa_crypto.function`:
  Consecutive changes in the two branches, reconciled.

Jaeden Amero 8dd1690993 Merge remote-tracking branch 'tls/development' into development
Resolve conflicts by performing the following operations:
- Reject changes related to building a crypto submodule, since Mbed
  Crypto is the crypto submodule.
- Reject X.509, NET, and SSL changes.
- Reject changes to README, as Mbed Crypto is a different project from
  Mbed TLS, with a different README.
- Avoid adding mention of ssl-opt.sh in a comment near some modified
  code in include/CMakeLists.txt (around where ENABLE_TESTING as added).
- Align config.pl in Mbed TLS with config.pl in Mbed Crypto where PSA
  options are concerned, to make future merging easier. There is no
  reason for the two to be different in this regard, now that Mbed TLS
  always depends on Mbed Crypto. Remaining differences are only the
  PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER option and the absence of X.509,
  NET, and SSL related options in Mbed Crypto's config.pl.
- Align config.h in Mbed Crypto with Mbed TLS's copy, with a few notable
  exceptions:
  - Leave CMAC on by default.
  - Leave storage on by default (including ITS emulation).
  - Avoid documenting the PSA Crypto API as is in beta stage in
    documentation for MBEDTLS_PSA_CRYPTO_C.
  The only remaining differences are a lack of X.509, NET, and SSL
  options in Mbed Crypto's config.h, as well as an additional
  Mbed-Crypto-specific PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER option.
  Documentation for the check params feature and related macros is also
  updated to match Mbed TLS's description.
- Reject tests/data_files/Makefile changes to generate DER versions of
  CRTs and keys, as none of those are used by Mbed Crypto tests.
- Add the "no PEM and no filesystem" test to all.sh, without ssl-opt.sh
  run, as Mbed Crypto doesn't have ssl-opt.sh. Also remove use of PSA
  Crypto storage and ITS emulation, since those depend on filesystem
  support.
- Reject addition of test when no ciphersuites have MAC to all.sh, as
  the option being tested, MBEDTLS_SSL_SOME_MODES_USE_MAC, is not
  present in Mbed Crypto.
- Use baremetal config in all.sh, as Mbed Crypto's baremetal
  configuration does exclude the net module (as it doesn't exist in Mbed
  Crypto)
- Reject cmake_subproject_build changes, continuing to link only
  libmbedcrypto.
- Reject changes to visualc and associated templates. Mbed Crypto
  doesn't need additional logic to handle submodule-sourced headers.
- Avoid adding fuzzers from Mbed TLS. The only relevant fuzzers are the
  privkey and pubkey fuzzers, but non-trivial work would be required to
  integrate those into Mbed Crypto (more than is comfortable in a merge
  commit).
- Reject addition of Docker wrappers for compat.sh and ssl-opt.sh, as
  those are not present in Mbed Crypto.
- Remove calls to SSL-related scripts from basic-in-docker.sh

Fix test errors by performing the following:
- Avoid using a link that Doxygen can't seem to resolve in Mbed Crypto,
  but can resolve in Mbed TLS. In documentation for
  MBEDTLS_CHECK_PARAMS, don't attempt to link to MBEDTLS_PARAM_FAILED.

Gilles Peskine 84867cffdd Don't use dynamic pointer dispatch in md
In the generic message digest abstraction, instead of storing method
pointers in the per-algorithm data structure and using wrapper
functions as those methods, call the per-algorithm function directly.

This saves some code size (2336B -> 2043B for md with all algorithms
enabled on M0+ with gcc -Os). This should also make it easier to
optimize the case when a single algorithm is supported. In addition,
this is a very slight security improvement since it removes one
opportunity for a buffer overflow to directly turn into letting the
attacker overwrite a pointer to a function pointer.

This commit does not modify the documented API. However, it removes
the possibility for users to define their own hash implementations and
use them by building their own md_info.

Changing mbedtls_md_context to contain a md type identifier rather
than a pointer to an info structure would save a few more bytes and a
few more runtime memory accesses, but would be a major API break since
a lot of code uses `const mbedtls_md_info *` to keep track of which
hash is in use.

Gilles Peskine 85aba47715 Consistently spell -Wextra

Manuel Pégourié-Gonnard d8167e85d6 Build from submodule by default (make, cmake)
Adapt tests in all.sh:
- tests with submodule enabled (default) no longer need to enable it
  explicitly, and no longer need runtime tests, as those are now handled by
all other test cases in this script
- tests with submodule disabled (old default) now need to disable it
  explicitly, and execute some runtime tests, as those are no longer tested
anywhere else in this script

Adapt documentation in Readme: remove the section "building with submodule"
and replace it with a new section before the other building sections.
Purposefully don't document how to build not from the submodule, as that
option is going away soon.

Jaeden Amero 8d4d4f55f0 Makefile: Use full paths to refer to parent files
When running lcov, files can't be found relative to the parent project
(Mbed TLS) root. Use full, non-relative paths to refer to files used in
building Mbed Crypto from Mbed TLS in order to enable lcov to locate the
files properly.

Jaeden Amero 92da0bd862 Makefile: Use generated source files from parent

Jaeden Amero 8df5de42e2 Makefile: Output to explicit target
Don't depend on the C compiler's default output file name and path. Make

always align with the C compiler default, so tell the C compilter to
output to the Make target explicitly.

Gilles Peskine 088b77f39c Merge psa_crypto_storage_its into psa_crypto_storage
Since the ITS API has stabilized and we don't plan to make use of more
than ITS, we don't need an abstraction layer between key storage and
key storage over ITS. Merge the ITS code into the generic storage
module.
2019-03-15 11:15:01 +01:00
Gilles Peskine e435f23019 Remove psa_crypto_storage_file
Now that we have ITS over files, we no longer need a direct backend
for key storage over files. Remove psa_crypto_storage_file and its
tests.

Switch MBEDTLS_PSA_CRYPTO_STORAGE_ITS_C and MBEDTLS_PSA_ITS_FILE_C on
by default. This preserves functionality and test coverage in the
default configuration, but forgets any key previously stored using the
file backend.

Jaeden Amero 67ea2c5e6d Merge branch 'development-psa-proposed' into development
Resolve conflicts by performing the following.

- Take the upstream Mbed TLS ChangeLog verbatim.
- Reject changes to Makefiles and CMake that are related to using Mbed
  Crypto as a submodule. It doesn't make sense to use Mbed Crypto as a
  submodule of itself.
- Reject README changes, as Mbed Crypto has its own, different README.
- Reject PSA-related changes to config.h. We don't want to disable the
  availability of the PSA Crypto API by default in the Mbed Crypto
  config.h.
- Don't inadvertently revert dead code removal in
  mbedtls_cipher_write_tag() which was added in f2a7529403 ("Fix
  double return statement in cipher.c")
- Where Mbed Crypto already had some MBEDTLS_USE_PSA_CRYPTO code (from
  past companion PRs) take the latest version from Mbed TLS which
  includes integration with MBEDTLS_CHECK_PARAMS.
- Update the version of the shared library files to match what's
  currently present in Mbed TLS.
- Reject removal of testing with PSA from config full tests.
- Resolve conflicts in test tests/suites/helpers.function, where both
  Mbed Crypto and Mbed TLS both added documentation for TEST_ASSERT.
  Combine text from both documentation efforts.
- Reject adding a submodule of ourselves.
- Reject addition of submodule tests in all.sh.
- Reject addition of submodule to library path in
  tests/scripts/run-test-suites.pl.
- Avoid using USE_CRYPTO_SUBMODULE=1 in
  component_test_use_psa_crypto_full_cmake_asan() in all.sh.

Gilles Peskine 961849f6d1 Implement slot allocation
Implement psa_allocate_key, psa_open_key, psa_create_key,
psa_close_key.

Add support for keys designated to handles to psa_get_key_slot, and
thereby to the whole API.

Allocated and non-allocated keys can coexist. This is a temporary
stage in order to transition from the use of direct slot numbers to
allocated handles only. Once all the tests and sample programs have
been migrated to use handles, the implementation will be simplified
and made more robust with support for handles only.

Jaeden Amero c6e4ab00a8 Use parent module includes when used as a submodule
For Makefiles, enable overriding where includes can come from in order to
enable the parent module to set the include path. This allows the parent
module to specify that its config.h should be used, even when the submodule
when built standalone would use a different config.h.

For CMake, always look in the parent's include folder and our own. List the
parent's include folder first, so that preference is given to parent
include files.

Darryl Green db2b8db715 psa: Add storage implementation for files
Add new functions, psa_load_persistent_key(),
psa_free_persistent_key_data(), and psa_save_persistent_key(), for
managing persistent keys. These functions load to or save from our
internal representation of key slots. Serialization is a concern of the
storage backend implementation and doesn't abstraction-leak into the
lifetime management code.

An initial implementation for files is provided. Additional storage
backends can implement this interface for other storage types.

Manuel Pégourié-Gonnard dca3a5d884 Rename aead_chacha20_poly1305 to chachapoly
While the old name is explicit and aligned with the RFC, it's also very long,
so with the mbedtls_ prefix prepended we get a 31-char prefix to each
identifier, which quickly conflicts with our 80-column policy.

The new name is shorter, it's what a lot of people use when speaking about
that construction anyway, and hopefully should not introduce confusion at
it seems unlikely that variants other than 20/1305 be standardised in the
foreseeable future.
