@christmart can you provide some information on how OpenSSL is packaged for s390x? Failures here could also be due to the lack of EC support being compiled in.
We'll work on a way to get more detailed errors reported from OpenSSL otherwise.

@linuxwolf the errors occur in a build of 0.4.1 which was released before reformatting; so jws.c:536 refers to this line:
Line 536 in 67eba48
from cjose.

@zandbelt @christmart there are only three ways for cjose_base64url_encode to fail:
- memory errors
- NULL or 0 input
- NULL outputs
The jws.c code definitely prevents # 3 from happening, which leaves either memory errors or bad inputs. I think I recall some versions of OpenSSL with EC features compiled out would not return errors, but might not return values either.

Hi,
maybe this is a hint about the problems with build on s390x.

The attachement of the previous message is missing.
I got the following hint from Aurelien Jarno [email protected]:
Looking at the failures, it seems to fails on all 64-bit big-endian
architectures (ppc64, s390x, sparc64). Looking at the code, there is
an issue with at least this part of the code from jws.c:
if (RSA_sign(digest_alg, jws->dig, jws->dig_len, jws->sig, (unsigned int *)&jws->sig_len, (RSA *)jwk->keydata) != 1)
You can't cast a pointer to a pointer of different size.

Thanks for the hint. I don't see anything in the openssl configuration items that point to a particular problem. That line is certainly a bug that should be addressed, but I have no way to confirm it's the cause of this issue.

If you have a fix for this, I can test if it helps for the original problem.

The patch is working and also fixes the problem with the failing test after building on s390x, sparc64 and ppc64.
