Comment 1 Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2020-04-12 18:53:51 UTC
To be honest, I think this issue may actually be arch-specific.  Could you reproduce it on some other arch in your arsenal?  ;-)

Ago, would you be able to run it through all arches under your disposal and let me know if some of them fail?
Comment 2 Rolf Eike Beer 2020-04-12 19:12:34 UTC
happens the same on hppa (which also has more errors)

It's an unstream endianness bug in acl.c where mode_t was assumed to be unsigned short. Fixed upstream in https://github.com/iustin/pylibacl/commit/2c3c52bcf087c25a5ce58a68968b53f985b77d73.

Comment 5 Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2020-04-13 06:24:59 UTC
I'm confused.  Why is your patch different than upstream's?  Is it because of surrounding code, or does upstream still do it wrong?  If just the former, I think it'd make more sense to do a snapshot.

Comment 7 Sergei Trofimovich gentoo-dev 2020-04-17 17:46:21 UTC
Upstream fixed it in a few iterations.

Initially it used format string "H" (unsigned short) and mode_t* (unsigned int*) mismatch. Then moved away from "H" format string into using runtime inspection of the object type (API change). Probably to workaround obscure bugs caused in other system. Upstream's final state looks reasonable.

But I did not succeed building upstream master with python2.7. I'm not sure I tried properly though.

One-liner to match actual type passed for "H" format string looks least invasive without changing program's semantics.
Comment 8 Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2020-04-18 05:11:56 UTC
I've added 0.5.4 (which is the last release supporting Python 2) and the current snapshot.  I'd appreciate if you could test both and compare the results.
Comment 9 Rolf Eike Beer 2020-04-18 08:59:50 UTC
The snapshot passes tests, 0.5.4 fails with:
