Gilles Peskine cbd91e013c Fix entropy_threshold when MBEDTLS_TEST_NULL_ENTROPY is enabled
Don't use the default entropy sources so as not to depend on their
characteristics.

Gilles Peskine 65fc0686a7 Add tests to ensure that we gather as much entropy as expected
There were tests to ensure that each entropy source reaches its
threshold, but no test that covers the total amount of entropy. Add
test cases with a known set of entropy sources and make sure that we
always gather at least MBEDTLS_ENTROPY_BLOCK_SIZE bytes from a strong
source.

Gilles Peskine ed04a676ee Entropy tests: support multiple dummy sources
Always pass a context object to entropy_dummy_source. This lets us
write tests that register more than one source and keep track of how
many times each one is called.

Gilles Peskine 66afcca5a9 entropy_nv_seed: cope with SHA-256
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.

Gilles Peskine e39b903de5 entropy_nv_seed: clean up properly
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.

Jaeden Amero f7dca86522 Allow building with the -Wunused flag
Make some functions non-static, to avoid Wunused function warnings. Make
a function scoped variable block scoped instead, to avoid Wunused
variable warnings in some configurations.

Hanno Becker d4a872ee67 Rename internal MBEDTLS_ENTROPY_HAVE_STRONG to ENTROPY_HAVE_STRONG
This commit renames the test-only flag MBEDTLS_ENTROPY_HAVE_STRONG to ENTROPY_HAVE_STRONG to make it more transparent
that it's an internal flag, and also to content the testscript tests/scripts/check-names.pl which previously complained
about the macro occurring in a comment in `entropy.c` without being defined in a library file.

Simon Butcher b7f45c54a7 Fixes for entropy test suite for some configurations
Changes to allow the entropy tests to work for configurations without an
entropy seed file (MBEDTLS_ENTROPY_NV_SEED), and with no entropy sources
configured (MBEDTLS_TEST_NULL_ENTROPY).

Andres AG e7723ec284 Make entropy bias self test poll multiple times
Instead of polling the hardware entropy source a single time and
comparing the output with itself, the source is polled at least twice
and make sure that the separate outputs are different.

Andres AG b34e42e69e Add a new self test to entropy module
The self test is a quick way to check at startup whether the entropy
sources are functioning correctly. The self test only polls 8 bytes
from the default entropy source and performs the following checks:

- The bytes are not all 0x00 or 0xFF.
- The hardware does not return an error when polled.
- The entropy does not provide data in a patter. Only check pattern
  at byte, word and long word sizes.

Paul Bakker ffbfb4c24c Add test cases for NV seed functionality
A standard 'test' that writes a seed file is added so that regular tests
still can succeed. This is in lieu of a 'SUITE_PRE_CODE' kind of
arrangement where a suite can run code before (and after) all other code
runs.

A test is added that checks if we can read and write the standard NV
seed file

A test is added that actually checks if the entropy and seed file values
that are the result of just using the NV seed are the same as the manual
calculation.
