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).
In some tests in ssl-opt.sh the client finishes sooner and the server
gets killed before it could reach certain errors. Consequently the
the script doesn't find the error it is looking for and the test fails.
To resolve this issue, we introduce a per-test option to wait after the
client finishes.
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.
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.
In the test script tests/scripts/all.sh the armcc build is a baremetal build
and doesn't use MBEDTLS_HAVE_TIME therefore the test configuration
MBEDTLS_PLATFORM_TIME_ALT which is dependent on it must be unset.
The test script tests/scripts/all.sh exits on first error, although it also
attempted to redirect error output from armcc and then output it after armcc
had completed. This never occurred because as soon as armcc failed the script
would end and the redirected output wouldn't be displayed.
This change removes that redirection.
* Add script to print build environment info.
The new script is also included in:
- all.sh
- basic-build-test.sh
* Tidy up environment reporting script.
Changes include:
- making the echo calls portable
- removing unnecessary brackets
- using more efficient checks for the existance of commands
- correcting typos and copyright year
* Update references to output_env.sh
MBEDTLS_ENTROPY_NV_SEED is dependent on platform code unless an
alternative implementation is provided, therefore needs to be disabled
in the disabled filesystem IO build.
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.
Running valgrind on: "DTLS client reconnect from same port: reconnect,
nbio" results in timeouts.
New version added that runs only under valgrind. Original only runs when
valgrind is not used
The glibc package recently enabled compressed debug symbols but valgrind doesn't
support them yet.
Results in messages like:
--14923-- WARNING: Serious error when reading debug info
--14923-- When reading debug info from /lib/x86_64-linux-gnu/ld-2.21.so:
--14923-- Ignoring non-Dwarf2/3/4 block in .debug_info
First line has 'error' in it which triggers some of the ssl-opt tests
The configuration MBEDTLS_MEMORY_BACKTRACE is intended for debug and
is not necessary for test coverage. Because it causes timing problems
in some tests the configuration has been removed as it's not present in
equivalent tests in the all.sh test script.
In order to reduce debugging time, allows you to only run interesting
tests (by number) from the commandline.
e.g. the command 'tests/ssl-opt.sh -n 246,258' will only run test 246
and 258 (as per the number in the log file names)
For a start, they don't even compile with Visual Studio due to strcasecmp
being missing. Secondly, on Windows Perl scripts aren't executable and have
to be run using the Perl interpreter directly; thankfully CMake is able to
find cygwin Perl straight away without problems.

The commit adds to the generate_code.pl script support to add #line directives
to generated code to allow build breaks to be more easily found from the
generated code.
