[Windows] Running tests

[sfhacker]

Hi.

We are new to this project and have just built master branch from source on Windows 10 x64. While running tests one of them is failing. No idea how to debug/troubleshoot this issue. Any pointers would be greatly appreciated. Cheers.

All other tests are ok. For example:

Do I correctly understand that you use Linux subsystem on Windows? Which OpenSSL version do you use? Could you please provide a stack trace of the segfault?

[sfhacker]

Thanks for your prompt response (and in English language!). No Linux subsystem, thank you very much!

We have already provided a stack trace.

Thanks again.

evp_cipher_init_internal (where the SEGFAULT happens) is internal OpenSSL function. So the problem look to be present in OpenSSL (or in the engine tests). I kindly ask you to build OpenSSL (and gost engine/provider) with debug info to get more information from the stack trace.

The upstream behaviour was recently fixed by https://github.com/openssl/openssl/pull/20662, could you please check that you have this fix in your build tree? If it is present and the issue is still reproducible, I'd recommend raise it against OpenSSL.

[sfhacker]

Pardon my ignorance, but what is the difference between an engine and a provider? Why do we need both at the same time? That bizarre thing seems to cause more problems than benefits (see, for instance, #18487).

We will continue debugging/troubleshooting further and report here.

Cheers.

Well. There was an engine I have been maintaining for ages and now there is also a provider which unfortunately isn't as capable as engine was because I don't have enough capacity now

[sfhacker]

If, for whatever reason, BOTH the engine and the provider are enabled (or active), a segmentation fault is thrown! (See here). Is it possible to refactor the code and 'merge' (or conflate) both into one? The 'gost_prov.c' file is using/calling code from 'eng_prov.c' file. Even though it is/tries to be a wrapper, it smells!. If ONLY the provider is enabled, then almost all tests fail. The test files in this repo (e.g. test_digest, etc), are they engine tests only?

You failed to answer/explain the question/difference between them. Anyway, that's ok.

Regarding the failing test posted here, I have built OpenSSL master branch from source 'in debug mode' and this the backtrace:

We know nothing about this project as to understand what is going on here! It looks like Russian language! Any ideas/hints how I can further troubleshoot this issue?

Thanks in advance.

[beldmit]

Currently you don't have any reasons to use GOST engine and provider together. The engine is enough.

In future there are chances that someone (probably me) will rewrite it to provider model completely. Patches are strongly welcome.

More testing (and gratis!) ...

Any ideas?

By the way, which version number is master branch at? 1.0? 3.0.4-dev?

[beldmit]

No ideas. What do you use, engine or provider? Looks like it tries to go the provider way
