Description Ayman Khamouma 2016-06-08 11:27:51 UTC 
Description of problem:
/usr/libexec/lxc/lxc-user-nic is missing the suid bit.

Version-Release number of selected component (if applicable):
lxc version 1.1.5

How reproducible:
try running an unprivileged lxc (see: http://blog.attackzero.net/2016/02/adventures-in-containerization-part-2.html)

Steps to Reproduce:
1. configure an unprivileged lxc like in attackzero's blog
2. configure network (veth)
3. start the lxc

Actual results:
operation not permitted (on network configuration)

Expected results:
guest boot and network properly configured


Additional info:
add suid bit to /usr/libexec/lxc/lxc-user-nic to fix the problem.
PS: see post about this from stephane grabber himself: https://www.stgraber.org/2014/01/17/lxc-1-0-unprivileged-containers/
Comment 1 Fedora End Of Life 2016-11-25 09:14:37 UTC 
This message is a reminder that Fedora 23 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 23. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '23'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 23 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.
