e30d03e4f4 Change the use of pylint to optionally use pylint3
Pylint when installed as a distro package can be installed as pylint3, whilst as
a PEP egg, it can be installed as pylint.

This commit changes the scripts to first use pylint if installed, and optionally
look for pylint3 if not installed. This is to allow a preference for the PEP
version over the distro version, assuming the PEP one is more likely to be
the correct one.

765d240ca6 Test component with malloc(0) returning NULL: run some ssl tests 2020-02-11 19:26:28 +01:00
Gilles Peskine
c4ef7a9de3 Add a test component with malloc(0) returning NULL
Exercise the library functions with calloc returning NULL for a size
of 0. Make this a separate job with UBSan (and ASan) to detect
places where we try to dereference the result of calloc(0) or to do
things like

    buf = calloc(size, 1);
    if (buf == NULL && size != 0) return INSUFFICIENT_MEMORY;
    memcpy(buf, source, size);

which has undefined behavior when buf is NULL at the memcpy call even
if size is 0.

This is needed because other test components jobs either use the system
malloc which returns non-NULL on Linux and FreeBSD, or the
memory_buffer_alloc malloc which returns NULL but does not give as
useful feedback with ASan (because the whole heap is a single C
object).

7cb47de12a query_config: Move to programs/test
As the SSL programs, like ssl_client2 and ssl_server2, are dependent on
SSL and therefore about to be removed, the only consumer of query_config
is the query_compile_time_config test. As such, it makes sense to move
query_config to be next to what uses it.

ec10bf1385 Test GCC and Clang with common build options
Goals:
* Build with common compilers with common options, so that we don't
  miss a (potentially useful) warning only triggered with certain
  build options.
* A previous commit removed -O0 test jobs, leaving only the one with
  -m32. We have inline assembly that is disabled with -O0, falling
  back to generic C code. This commit restores a test that runs the
  generic C code on a 64-bit platform.

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.

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.

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.

8fa1348276 Enumerate metadata test functions explicitly

asymmetric_signature_wildcard was silently ignored as a source of

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.

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.

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.

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.

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.

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.

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.

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.

2e86a206f7 Remove component designed to test MAX_SIGNATURE_SIZE
MBEDTLS_PK_SIGNATURE_MAX_SIZE is tested in Mbed Crypto. Its effect on
Mbed TLS is also tested via the X.509 tests. The case of
MBEDTLS_MPI_MAX_SIZE < MBEDTLS_ECDSA_MAX_LEN, for which this component
was added as a regression test, is covered by config-suite-b.h which
is tested via test-ref-configs.pl.

ce35cb3cc7 'make test' must fail if Asan fails
When running 'make test' with GNU make, if a test suite program
displays "PASSED", this was automatically counted as a pass. This
would in particular count as passing:
* A test suite with the substring "PASSED" in a test description.
* A test suite where all the test cases succeeded, but the final
  cleanup failed, in particular if a sanitizer reported a memory leak.

Use the test executable's return status instead to determine whether
the test suite passed. It's always 0 on PASSED unless the executable's
cleanup code fails, and it's never 0 on any failure.

Add a reference configuration with most symmetric cryptographic
algorithms enabled, but without any asymmetric cryptography. This
checks that we don't have spurious unexpected dependencies on
asymmetric-only modules such as bignum.

Keep HAVE_ASM disabled because it's platform-specific.

Keep HAVEGE disabled because it's untested and not recommended.

Keep MEMORY_BUFFER_ALLOC out because it isn't related to cryptography
at all and it makes memory sanitizers ineffective.

Keep THREADING disabled because it requires special build options.

Since components run in the main process, unsetting

To avoid this, save and restore the value.

31b0a3c351 Add a test component with malloc(0) returning NULL
Exercise the library functions with calloc returning NULL for a size
of 0. Make this a separate job with UBSan (and ASan) to detect
places where we try to dereference the result of calloc(0) or to do
things like

    buf = calloc(size, 1);
    if (buf == NULL && size != 0) return INSUFFICIENT_MEMORY;
    memcpy(buf, source, size);

which has undefined behavior when buf is NULL at the memcpy call even
if size is 0.

This is needed because other test components jobs either use the system
malloc which returns non-NULL on Linux and FreeBSD, or the
memory_buffer_alloc malloc which returns NULL but does not give as
useful feedback with ASan (because the whole heap is a single C
object).
