Description of problem:
It was not possible to install few packages for sssd.

Version-Release number of selected component (if applicable):
-bash-4.3$ rpm -q yum mock rpm
yum-3.4.3-507.fc23.noarch
mock-1.2.13-2.fc23.noarch
rpm-4.13.0-0.rc1.3.fc23.x86_64

How reproducible:
Deterministic

Steps to Reproduce:
1. Install the latest 23
2. setup mock
3. try to rebuild sssd from koji
   wget https://kojipkgs.fedoraproject.org//packages/sssd/1.13.1/1.fc24/src/sssd-1.13.1-1.fc24.src.rpm
4. /usr/bin/mock --root fedora-23-x86_64 --resultdir . --rebuild sssd-1.13.1-1.fc24.src.rpm

Actual results:
Preparation of chroot failed.
and rpms was not created.

Expected results:
rpms are created.

Additional info:
It works on fedora 23 with package manager dnf.
-bash-4.3$ grep dnf /etc/mock/fedora-rawhide-x86_64.cfg 
config_opts['package_manager'] = 'dnf'

Comment 2 Miroslav Suchý 2015-10-05 17:47:21 UTC 
I can confirm that it fails with --yum and succeed with --dnf.
Mock on F23 use python3, F22 use python2. However even if I changed shebang of mock to python2 it still behave the same, so that is not an issue.
I tested it in permissive mode - it still fails. I will try it in disabled tomorrow.
Comment 3 Miroslav Suchý 2015-10-05 17:50:04 UTC 
Valentina - as this happen only with yum, do you have an idea what can be the cause?
Comment 4 Lukas Slebodnik 2015-10-06 08:38:19 UTC 
It works fine on fedora 22 with the same root (fedora-23-x86_64). It works with yum and dnf.
Comment 5 Miroslav Suchý 2015-10-06 09:17:14 UTC 
It works with SELinux disabled - therefore flipping to selinux component. If you find that there is something bad in mock then do not hesitate to flip it back.

Strange part is that in audit.log there is no denied lines. Only those (beside success ones):

Do you mean with permissive mode? Let me to test it.

Ah, I see it. You mean disabled ;-).
Comment 8 Lukas Slebodnik 2015-10-06 10:11:40 UTC 
I cannot see any avc or user_avc even with disabled dontaudit.
Comment 9 Lukas Slebodnik 2015-10-06 10:18:56 UTC 
IMHO, the most important fact is that it works on fedora 22.
So I tried to downgrade few mock dependencies (f23->f22) and it seems that bug is caused by one of following packages:

  Downgrading : rpm-plugin-selinux-4.12.0.1-12.fc22.x86_64                1/26

I had to downgrade them in bulk due to dependencies.
Comment 10 Lukas Slebodnik 2015-10-06 10:22:55 UTC 
So chroot can be prepared with yum after downgrading packages and it also fix errors in scriptlets.

Yes, I see the same issue.
Comment 12 Miroslav Suchý 2015-10-06 16:07:45 UTC 
How is it possible that it works with selinux disabled and it does not work in permissive mode?
I am only aware of:
  http://danwalsh.livejournal.com/?skip=20#post-danwalsh-67855
but I do not see those in logs.

I'd say this is a regression in the rpm plugin, caused by this commit:
http://rpm.org/gitweb?p=rpm.git;a=commitdiff;h=148e82833a384b438547c2d3610e3df4a50cf997

The new code path using setexecfilecon() misses this fairly subtle quirk:

Do you know why there is not a problem with dnf?

/usr/bin/mock --dnf --root fedora-23-x86_64 --resultdir . --rebuild sssd-1.13.1-1.fc24.src.rpm

Does the dnf ignores such errors or does dnf implement something differently which should be fixed?
Comment 16 Panu Matilainen 2015-10-08 08:30:37 UTC 
Sorry, no idea. Could be many things, like differences between rpm transaction flags (plugins or no plugins, contexts or no contexts) and whatnot.

It might be worth to file a tracking ticket to investigate it.
I hope dnf do not ignore such important things as setexecfilecon or some rpm plugins.

Yeah, figuring out where exactly the difference comes from is indeed important. That dnf is not affected by this suggests it might not be setting the contexts at all, but whether its due to differences from mock cli options or dnf vs yum themselves...
Comment 19 Lukas Slebodnik 2015-10-12 06:22:51 UTC 
Panu,

Could you backport patch to fedora rawhide and fedora 23?
ATM, I am not able to rebuild src.rpm for epel* on my fedora 23.
Neither yum nor dnf is usable with  mock on my machine.
Comment 20 Panu Matilainen 2015-10-12 09:44:19 UTC 
That is up to the current rpm maintainers. I'm no longer directly involved, I merely pointed out the likely culprit.
