Bug 1416813

Description of problem:

The following command gives an error:

docker run --cap-add=SYS_ADMIN --name 7-f23-d41d8cd98f00b204e9800998ecf8427e -v /tmp/tmplCbW9M:/tmp/tmplCbW9M -w /tmp/tmplCbW9M 8dad1bfbf15d /usr/bin/mock -r fedora-rawhide-x86_64 --uniqueext 7-f23 --scm-enable --scm-option method=git --scm-option package=example --scm-option branch= --scm-option write_tar=True --scm-option spec=subpkg/example.spec --scm-option git_get=git clone --depth 1 https://github.com/clime/example2.git example --buildsrpm --resultdir=/tmp/tmplCbW9M

The error is:

With selinux disabled, the error no longer occurs.

Version-Release number of selected component (if applicable):
Name        : docker
Arch        : x86_64
Epoch       : 2
Version     : 1.12.6
Release     : 5.git037a2f5.fc25

Name        : mock
Arch        : noarch
Epoch       : 0
Version     : 1.3.3
Release     : 1.fc25

How reproducible:
Always


Actual results:
The command fails to build srpm.

Expected results:
The command builds srpm.

Additional info:
The command is run from a service on a machine providing dist-git repos. That machine has currently selinux disabled so this is not a critical issue. When trying to reproduce the issue in shell I encountered another error that also disappeared after disabling SELinux:
