Gilles Peskine f65ed6f254 Change key types to a 16-bit encoding
All key types now have an encoding on 32 bits where the bottom 16 bits
are zero. Change to using 16 bits only.

Keep 32 bits for key types in storage, but move the significant
half-word from the top to the bottom.

Likewise, change EC curve and DH group families from 32 bits out of
which the top 8 and bottom 16 bits are zero, to 8 bits only.

Reorder psa_core_key_attributes_t to avoid padding.
2020-01-31 10:24:21 +01:00
Gilles Peskine 228abc5773 Define EC curve family constants
Define constants for ECC curve families and DH group families. These
constants have 0x0000 in the lower 16 bits of the key type.

Support these constants in the implementation and in the PSA metadata
tests.

Switch the slot management and secure element driver HAL tests to the
new curve encodings. This requires SE driver code to become slightly
more clever when figuring out the bit-size of an imported EC key since
it now needs to take the data size into account.

Switch some documentation to the new encodings.

Remove the macro PSA_ECC_CURVE_BITS which can no longer be implemented.

Gilles Peskine 325584889d Add option to show what values are tested
This is useful to inspect what the script does manually, in particular
to check that expected values do get tested. --keep-c provides the
same information but in a way that's harder to access.

Gilles Peskine 49af2d3a4f Support non-ASCII characters in headers
Filter out non-ASCII characters in automatically processed headers.

Do this in a way that minimizes the code change: keep manipulating
strings, but strip off non-ASCII characters when reading lines, which
should only remove characters in comments that we don't parse anyway.
2019-12-11 11:03:07 +01:00
Gilles Peskine 841b14be02 Add tests of deprecated PSA macros
When MBEDTLS_TEST_DEPRECATED is defined, run some additional tests to
validate deprecated PSA macros. We don't need to test deprecated
features extensively, but we should at least ensure that they don't
break the build.

Add some code to component_build_deprecated in all.sh to run these
tests with MBEDTLS_DEPRECATED_WARNING enabled. The tests are also
executed when MBEDTLS_DEPRECATED_WARNING and
MBEDTLS_DEPRECATED_REMOVED are both disabled.
2019-11-26 19:12:35 +01:00
Gilles Peskine 7a894f2142 Move backward compatibility aliases to their own header
Move backward compatibility aliases to a separate header. Reserve
crypto_extra.h for implementation-specific extensions that we intend
to keep supporting.

This is better documentation for users. New users should simply ignore
backward compatibility aliases, and old users can look at
crypto_compat.h to see what is deprecated without bothering about new
features appearing in crypto_extra.h.

This facilitates maintenance because scripts such as
generate_psa_constants that want to ignore backward compability
aliases can simply exclude crypto_compat.h from their parsing.

Gilles Peskine 8fa1348276 Enumerate metadata test functions explicitly
When gathering test cases from test_suite_psa_crypto_metadata, look up
the test function explicitly. This way test_psa_constant_names will
error out if we add a new test function that needs coverage here.

This change highlights an omission in the previous version:
asymmetric_signature_wildcard was silently ignored as a source of
algorithm expressions to test. Fix that.
2019-11-25 17:10:12 +01:00
Gilles Peskine 7961668738 Support key agreement
Key agreement algorithms were excluded back when they were constructed
with a macro conveying the key agreement itself taking the KDF as an
argument, because that was hard to support. Now the encoding has
changed and key agreement algorithms are constructed with
PSA_ALG_KEY_AGREEMENT taking two arguments, one that identifies the
raw key agreement and one that identifies the KDF. This is easy to
process, so add support.
2019-11-25 15:44:24 +01:00
Gilles Peskine 2bcfc714d2 Error out if a test case uses an unknown macro name
Insist that test cases must only use macro names that are declared in
a header. This may catch errors such as not parsing the intended
files.

Make this check easily overridden in a derived class.

Gilles Peskine 592f591c0d all.sh: test CTR_DRBG_USE_128_BIT_KEY and ENTROPY_FORCE_SHA256
Test MBEDTLS_CTR_DRBG_USE_128_BIT_KEY and MBEDTLS_ENTROPY_FORCE_SHA256
together and separately.
2019-11-21 13:54:00 +01:00
Gilles Peskine 2ef377d56d all.sh: support variable seedfile size
The size of the seedfile used by the entropy module when
MBEDTLS_ENTROPY_NV_SEED is enabled is 32 byte when
MBEDTLS_ENTROPY_FORCE_SHA256 is enabled or MBEDTLS_SHA512_C is
disabled, and 64 bytes otherwise. A larger seedfile is ok on
entry (the code just grabs the first N bytes), but a smaller seedfile
is not ok. Therefore, if you run a component with a 32-byte seedfile
and then a component with a 64-byte seedfile, the second component
fails in the unit tests (up to test_suite_entropy which erases the
seedfile and creates a fresh one).

This is ok up to now because we only enable MBEDTLS_ENTROPY_NV_SEED
together with MBEDTLS_ENTROPY_FORCE_SHA256. But it prevents enabling
MBEDTLS_ENTROPY_NV_SEED without MBEDTLS_ENTROPY_FORCE_SHA256.

To fix this, unconditionally create a seedfile before each component.

Gilles Peskine 24600e8290 Disable memory_buffer_alloc in the full config
Enabling MBEDTLS_MEMORY_BUFFER_ALLOC_C module together with
MBEDTLS_PLATFORM_MEMORY causes the library to use its own malloc
replacement. This makes memory management analyzers such as ASan
largely ineffective. We now test MBEDTLS_MEMORY_BUFFER_ALLOC_C
separately. Disable it in the "full" config.

This mirrors a change that was made in Mbed TLS on config.pl and had
not been ported to Mbed Crypto yet.

With this commit, config.py is aligned in Mbed Crypto and Mbed TLS.

Gilles Peskine 9afbfdc833 Merge remote-tracking branch 'myfork-public/development' into merge-crypto-development-20191115
First deal with deleted files.

* Files deleted by us: keep them deleted.

git add -- $(git status -s | sed -n 's/^UD //p')
```

Individual files with conflicts:

* `3rdparty/everest/library/Hacl_Curve25519_joined.c`: spurious conflict because git mistakenly identified this file as a rename. Keep our version.
* `README.md`: conflict due to their change in a paragraph that doesn't exist in our version. Keep our version of this paragraph.
* `docs/architecture/Makefile`: near-identical additions. Adapt the definition of `all_markdown` and include the clean target.
* `doxygen/input/docs_mainpage.h`: conflict in the version number. Keep our version number.
* `include/mbedtls/config.h`: two delete/modify conflicts. Keep the removed chunks out.
* `library/CMakeLists.txt`: discard all their changes as they are not relevant.
* `library/Makefile`:
    * Discard the added chunk about the crypto submodule starting with `INCLUDING_FROM_MBEDTLS:=1`.
    * delete/modify: keep the removed chunk out.
    * library build: This is almost delete/modify. Their changes are mostly not applicable. Do keep the `libmbedcrypto.$(DLEXT): | libmbedcrypto.a` order dependency.
    * `.c.o`: `-o` was added on both sides but in a different place. Change to their place.
* `library/error.c`: to be regenerated.
* `library/version_features.c`: to be regenerated.
* `programs/Makefile`: Most of the changes are not relevant. The one relevant change is in the `clean` target for Windows; adapt it by removing `/S` from our version.
* `programs/test/query_config.c`: to be regenerated.
* `scripts/config.py`: added in parallel on both sides. Keep our version.
* `scripts/footprint.sh`: parallel changes. Keep our version.
* `scripts/generate_visualc_files.pl`: one delete/modify conflict. Keep the removed chunks out.
* `tests/Makefile`: discard all of their changes.
* `tests/scripts/all.sh`:
    * `pre_initialize_variables` add `append_outcome`: add it.
    * `pre_initialize_variables` add `ASAN_CFLAGS`: already there, keep our version.
    * `pre_parse_command_line` add `--no-append-outcome`: add it.
    * `pre_parse_command_line` add `--outcome-file`: add it.
    * `pre_print_configuration`: add `MBEDTLS_TEST_OUTCOME_FILE`.
    * Several changes in SSL-specific components: keep our version without them.
    * Several changes where `config.pl` was changed to `config.py` and there was an adjacent difference: keep our version.
    * Changes regarding the inclusion of `MBEDTLS_MEMORY_xxx`: ignore them here, they will be normalized in a subsequent commit.
    * `component_test_full_cmake_gcc_asan`: add it without the TLS tests.
    * `component_test_no_use_psa_crypto_full_cmake_asan`: keep the fixed `msg`, discard other changes.
    * `component_test_memory_buffer_allocator_backtrace`, `component_test_memory_buffer_allocator`: add them without the TLS tests.
    * `component_test_m32_everest`: added in parallel on both sides. Keep our version.

* `tests/scripts/test-ref-configs.pl`: the change in the conflict is not relevant, so keep our version there.
* `visualc/VS2010/*.vcxproj`: to be regenerated.

Regenerate files:

```

Rejected changes in non-conflicting files:

* `CMakeLists.txt`: discard their addition which has already been side-ported.
* `doxygen/mbedtls.doxyfile`: keep the version number change. Discard the changes related to `../crypto` paths.

Keep the following changes after examination:

* `.travis.yml`: all of their changes are relevant.
* `include/mbedtls/error.h`: do keep their changes. Even though Crypto doesn't use TLS errors, it must not encroach on TLS's allocated numbers.
* `tests/scripts/check-test-cases.py`: keep the code dealing with `ssl-opt.sh`. It works correctly when the file is not present.

Gilles Peskine adc82f3535 Add set+get tests
The tests were not covering get for a symbol with a value. No symbol
has an uncommented value in the default config.h. (Actually there's
_CRT_SECURE_NO_DEPRECATE, but that's a bit of a hack that this script
is not expected to handle, so don't use it).

Add tests of "get FOO" after "set FOO" and "set FOO value", so that we
have coverage for "get FOO" when "FOO" has a value.
2019-11-13 14:33:34 +00:00
Gilles Peskine bc86f997ca Consolidate tests for set with/without values
We currently test setting a symbol with a value even if it didn't
originally had one and vice versa. So there's no need to have separate
lists of symbols to test with. Just test everything we want to test
with each symbol.

Gilles Peskine 261742bd59 Fix config.py output when a symbol has acquired or lost a value
Normally a valueless symbol remains valueless and a symbol with a
value keeps having one. But just in case a symbol does get changed
from valueless to having a value, make sure there's a space between
the symbol and the value. And if a symbol gets changed from having a
value to valueless, strip trailing whitespace.

Add corresponding tests.

Also fix the case of a valueless symbol added with the set method,
which would have resulted in attempting to use None as a string. This
only happened with the Python API, not with the command line API.

Gilles Peskine aebf0027c0 Test script for config.py
Run config.py with various options and store the results in files.

This script also supports the now-removed config.pl.

This is a framework to run non-regression tests on config.py: run it
with the old version, run it with the new version, and compare the
output.

This is deliberately not a functional test suite so that we don't need
to maintain a set of known outputs. When something changes in
config.py (or config.h), run the script before, run it after, and
check manually whether any differences in the output are acceptable.
