Hello Gilles!

Thank you for your helpful answer! Unfortunately this solution to find memory leakage problems is not working under windows (as I read), but fortunately I was able to locate the source and now my changes are green on the server.

Thank you, again :)

BR, Gábor

Hi Gábor,

Thank you for contributing to Mbed TLS!

For the memory leaks, compile with ASan(+UBSan): export ASAN_OPTIONS='symbolize=1' # also export ASAN_SYMBOLIZER_PATH=/path/to/llvm-symbolizer if it's not found automatically export ASAN_FLAGS='-O2 -fsanitize=address,undefined -fno-sanitize-recover=all' make CFLAGS="$ASAN_FLAGS" LDFLAGS="$ASAN_FLAGS"

The SSL test scripts depend on precise versions of OpenSSL and GnuTLS. Versions that are too old are missing some features and recent versions have removed some features. Even some versions from Linux distributions have removed obsolete algorithms that we're still testing. If you want to pass all the tests on your machine, I recommend that you install them from source. There's a list of the versions we use on our CI at https://developer.trustedfirmware.org/w/mbed-tls/testing/ci/ .

When you're debugging, it's useful to run a single test case or a small number of test cases with ssl-opt -f 'regexp' . The logs are in tests/o-cli-<number>.log and tests/o-srv-<number>.log .

Hope this helps.

Hello Guys!

I am working on an update of MBEDTLS that will support AuthorityKeyId and SubjetKeyId V3 extensions of X509. I have created a pull request, but I have not been able to solve the issues on Travis: https://github.com/ARMmbed/mbedtls/pull/4117

As I see the problems are: memory leakage and the failure of two tests suites. I tried to run these suites and a memory leakage check on my host machine, but the .sh scripts are just flashing once and disappearing in a few seconds after catching some kind of exception.

I have Python2, Perl, Mingw64 (with gcc) installed and added to the Path. These commands are working:

• make CC=gcc
• make tests

All the 87 tests pass.

Tried running ssl-opt.sh without arguments and with "-m", but it exits after a few lines.

Do you have any idea what I am missing? It would make the work much easier if I could run the testsuites reproducing the error and if I could find the memory leaks.

Thank you in advance!

BR, Gábor
