Description of problem:
fter a recent update.  Starting nmcli or internet from NetworkManager throws an AVC. Initially, this prevented internet access until I disabled Selinux, relabelled all files an enabled Selinux again.

Now there is internet access but the AVCs persist

This is preventing live images from having network access, as /etc/resolv.conf is an empty file; note matching line in journalctl:

Jan 23 17:13:08 localhost NetworkManager[985]: <warn>  could not commit DNS changes: (0) Could not create symlink /etc/.resolv.conf.NetworkManager pointing to /var/run/NetworkManager/resolv.conf: Permission denied

I think it 'works' for Onyeibo after #c1 because NM managed to create resolv.conf while he was running with SELinux disabled, but if NM needed to *change* it at all, that wouldn't work.

Nominating as an Alpha blocker per criterion "It must be possible to run the default web browser and a terminal application from all release-blocking desktop environments. ... The web browser must be able to download files, load extensions (if applicable), and log into FAS." - it can't do that if the network doesn't work. https://fedoraproject.org/wiki/Fedora_22_Alpha_Release_Criteria#Required_applications

There is no new package with the fix for this bug yet, so of course it's not fixed in a current nightly.

    Allow apps that create net_conf_t content to create .resolv.conf.NetworkManager

I built a live image with selinux-policy -107 and it does not fix the bug, for me. On boot, I still have no /etc/resolv.conf and a bunch of AVCs relating to .resolv.conf.NetworkManager and resolv.conf . Filing them now.

    Fix labels, improve sysnet_manage_config interface.

I add fix for this issue. Also, doing build for F22 at the moment. Could you test this with selinux-policy-3.13.1-108.fc22 ?

Thank you.

Description of problem:
probly related to networkManager's dispatcher having a script tha tampers with /etc/resolv.conf , etc.

Version-Release number of selected component:
selinux-policy-3.13.1-107.fc22.noarch

Additional info:
reporter:       libreport-2.3.0
hashmarkername: setroubleshoot
kernel:         3.19.0-0.rc7.git0.3.fc22.x86_64
type:           libreport

OK, looks to be properly fixed with -110. Workstation live image boots and connects to the network with no AVCs.

Thank you for testing Adam.
