The corner case tests were designed for 32 and 64 bit limbs
independently and performed only on the target platform. On the other
platform they are not corner cases anymore, but we can still exercise
them.
The corner case tests were designed for 64 bit limbs and failed on 32
bit platforms because the numbers in the test ended up being stored in a
different number of limbs and the function (correctly) returnd an error
upon receiving them.
The signature of mbedtls_mpi_cmp_mpi_ct() meant to support using it in
place of mbedtls_mpi_cmp_mpi(). This meant full comparison functionality
and a signed result.
To make the function more universal and friendly to constant time
coding, we change the result type to unsigned. Theoretically, we could
encode the comparison result in an unsigned value, but it would be less
intuitive.
Therefore we won't be able to represent the result as unsigned anymore
and the functionality will be constrained to checking if the first
operand is less than the second. This is sufficient to support the
current use case and to check any relationship between MPIs.
The only drawback is that we need to call the function twice when
checking for equality, but this can be optimised later if an when it is
needed.
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.

Some sanitizers default to displaying an error message and recovering.
This could result in a test being recorded as passing despite a
complaint from the sanitizer. Turn off sanitizer recovery to avoid
this risk.

Reduce the stack usage of the `test_suite_pkcs1_v21` by reducing the
size of the buffers used in the tests, to a reasonable big enough size,
and change the size sent to the API to sizeof output.
Reduce the stack usage of the `test_suite_rsa` by reducing the
size of the buffers used in the tests, to a reasonable big enough size,
and change the data size to decrypt in the data file.
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).
With the removal of MBEDTLS_MEMORY_BUFFER_ALLOC_C from the
full config, there are no tests for it remaining in all.sh.
This commit adds a build as well as runs of `make test` and
`ssl-opt.sh` with MBEDTLS_MEMORY_BUFFER_ALLOC_C enabled to all.sh.
Previously, numerous all.sh tests manually disabled the buffer allocator
or memory backtracting after setting a full config as the starting point.
With the removal of MBEDTLS_MEMORY_BACKTRACE and MBEDTLS_MEMORY_BUFFER_ALLOC_C
from full configs, this is no longer necessary.
compat.sh used to skip OpenSSL altogether for DTLS 1.2, because older
versions of OpenSSL didn't support it. But these days it is supported.
We don't want to use DTLS 1.2 with OpenSSL unconditionally, because we
still use legacy versions of OpenSSL to test with legacy ciphers. So
check whether the version we're using supports it.
This test case was only executed if the SHA-512 module was enabled and
MBEDTLS_ENTROPY_FORCE_SHA256 was not enabled, so "config.pl full"
didn't have a chance to reach it even if that enabled
MBEDTLS_PLATFORM_NV_SEED_ALT.
Now all it takes to enable this test is MBEDTLS_PLATFORM_NV_SEED_ALT
and its requirements, and the near-ubiquitous MD module.
Call mbedtls_entropy_free on test failure.
Restore the previous NV seed functions which the call to
mbedtls_platform_set_nv_seed() changed. This didn't break anything,
but only because the NV seed functions used for these tests happened
to work for the tests that got executed later in the .data file.
Limit log output in compat.sh and ssl-opt.sh, in case of failures with
these scripts where they may output seemingly unlimited length error
logs.
Note that ulimit -f uses units of 512 bytes, so we use 10 * 1024 * 1024
* 2 to get 10 GiB.
