Raoul Strackx 2a8e9587a7 Always revoke certificate on CRL
RFC5280 does not state that the `revocationDate` should be checked.

In addition, when no time source is available (i.e., when MBEDTLS_HAVE_TIME_DATE is not defined), `mbedtls_x509_time_is_past` always returns 0. This results in the CRL not being checked at all.

Manuel Pégourié-Gonnard 426c2d4a38 Add an option to test constant-flow with valgrind
Currently the new component in all.sh fails because
mbedtls_ssl_cf_memcpy_offset() is not actually constant flow - this is on
purpose to be able to verify that the new test works.

Bence Szépkúti 44bfbe3b95 Update copyright notices to use Linux Foundation guidance
As a result, the copyright of contributors other than Arm is now
acknowledged, and the years of publishing are no longer tracked in the
source files.

Also remove the now-redundant lines declaring that the files are part of
MbedTLS.

Manuel Pégourié-Gonnard 2b223fd539 Add comment on memsan + constant-flow testing 2020-07-28 13:03:29 +02:00
Manuel Pégourié-Gonnard 40597cef01 Add MBEDTLS_TEST_CONSTANT_FLOW_MEMSAN
This option allows to test the constant-flow nature of selected code, using
MemSan and the fundamental observation behind ctgrind that the set of
operations allowed on undefined memory by dynamic analysers is the same as the
set of operations allowed on secret data to avoid leaking it to a local
attacker via side channels, namely, any operation except branching and
dereferencing.

(This isn't the full story, as on some CPUs some instructions have variable
execution depending on the inputs, most notably division and on some cores
multiplication. However, testing that no branch or memory access depends on
secret data is already a good start.)

Manuel Pégourié-Gonnard c09bb4c3ab all.sh: clean up some uses of "local" variables
While pure sh doesn't have a concept of local variables, we can partially
emulate them by unsetting variables before we exit the function, and use the
convention of giving them lowercase names to distinguish from global
variables.

Manuel Pégourié-Gonnard 73341a0f84 Add a --quiet option to all.sh
The primary purpose is to use it to run all.sh -k -q in the pre-push hook, but
this can be useful in any circumstance where you're not interested in the full
output from each component and just want a short summary of which components
were run (and if any failed).

Note that only stdout from components is suppressed, stderr is preserved so
that errors are reported. This means components should avoid printing to
stderr in normal usage (ie in the absence of errors).

Currently all the `check_*` components obey this convention except:
- check_generate_test_code: unittest prints progress to stderr
- check_test_cases: lots of non-fatal warnings printed to stderr

These components will be fixed in follow-up commits.

Manuel Pégourié-Gonnard 138109133d Remove SHA-1 as a fallback option
- it's 2020, there shouldn't be too many systems out there where SHA-1 is the
  only available hash option, so its usefulness is limited
- OTOH testing configurations without SHA-2 reveal bugs that are not easy to
  fix in a fully compatible way

So overall, the benefit/cost ratio is not good enough to justify keeping SHA-1
as a fallback option here.

Manuel Pégourié-Gonnard 6d61498e05 Add fall-back to hash-based KDF for internal ECP DRBG
The dependency on a DRBG module was perhaps a bit strict for LTS branches, so
let's have an option that works with no DRBG when at least one SHA module is
present.

This changes the internal API of ecp_drbg_seed() by adding the size of the
MPI as a parameter. Re-computing the size from the number of limbs doesn't
work too well here as we're writing out to a fixed-size buffer and for some
curves (P-521) that would round up too much. Using mbedtls_mpi_get_len() is
not entirely satisfactory either as it would mean using a variable-length
encoding, with could open side channels.

Manuel Pégourié-Gonnard c98fde5ca8 Add test for building without CTR_DRBG
People who prefer to rely on HMAC_DRBG (for example because they use it for
deterministic ECDSA and don't want a second DRBG for code size reasons) should
be able to build and run the tests suites without CTR_DRBG.

Ideally we should make sure the level of testing (SSL) is the same regardless
of which DRBG modules is enabled, but that's a more significant piece of work.
For now, just ensure everything builds and `make test` passes.

Gilles Peskine a21c5e9988 Document and fix the MBEDTLS_xxx_ALT logic for the full config
The intended logic around MBEDTLS_xxx_ALT is to exclude them from full
because they require the alternative implementation of one or more
library functions, except that MBEDTLS_PLATFORM_xxx_ALT are different:
they're alternative implementations of a platform function and they
have a built-in default, so they should be included in full. Document
this.

Fix a bug whereby MBEDTLS_PLATFORM_xxx_ALT didn't catch symbols where
xxx contains an underscore. As a consequence, MBEDTLS_PLATFORM_NV_SEED_ALT
is now enabled in the full config. Explicitly exclude
MBEDTLS_PLATFORM_SETUP_TEARDOWN_ALT because it behaves like the
non-platform ones, requiring an extra build-time dependency.
Explicitly exclude MBEDTLS_PLATFORM_NV_SEED_ALT from baremetal
because it requires MBEDTLS_ENTROPY_NV_SEED, and likewise explicitly
unset it from builds that unset MBEDTLS_ENTROPY_NV_SEED.

Gilles Peskine 0981a5d7ab 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).
