This unfortunately has created a build time dependency loop in yocto: python3 --> util-linux --> libselinux --> python3 (used to be python2 with 2.8 selinux userspace). Hi Peter, I had sent a series patches to update selinux usersapce tools from 2.8 ot 2.9: <https://www.yoctoproject.org/pipermail/yocto/2019-November/047329.html> https://www.yoctoproject.org/pipermail/yocto/2019-November/047329.html After switch to python3, there is a loop dependency error with libselinux-python package when build libselinux. So I split the original libselinux recipe into libselinux and libselinux-python. You can refer my patchset. Hi Yi, Great! Is there anything stopping these patches being merged? No, no issue as far as I can tell, I'm preparing another merge to master in the next couple of days. This includes Yi's patches, my update refpolicy purge feature and a few other things currently pending on the list from the last few weeks. -J. Excellent , thanks Joe. Peter. Thanks, Peter. //Yi Running "bitbake libselinux" results in a pile of loops, the one below illustrates the point.

It's proving a bit harder to track down the util-linux dependency on libselinux but I believe this is a hard depdency as well. I'm using the master branch of both poky and meta-selinux for testing, my local.conf file has the following to enable testing: DISTRO_FEATURES_append=" acl xattr pam selinux" The crux of the libselinux recipe change is really just changing the python2 deps over to python3 ones in meta-selinux/recipes- security/selinux/libselinux.inc. At this point I'd be trying to look for places where recipes can be split out to remove the loop, but nothing jumps out at me. Can anyone offer any advice or pointers on how to get around this? Or am I just stuffed? Many Thanks, Peter. -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.
