Description Laurent Wandrebeck 2013-10-05 03:08:53 EDT
Description of problem:
launched Networkmanager by hand as there was something buggy about network management in F20 alpha, updates-testing enabled. « Les services réseau du système ne sont pas compatibles avec cette version. » in french, gnome paramaters, network. Should be something like « Network services are not compatible with this version. »
Once NM launched (and properly gavec me network access, wifi and eth were both non functionnal before that), I got this SELinux alert.
SELinux is preventing /usr/libexec/nm-dhcp-helper from 'connectto' accesses on the unix_stream_socket /run/NetworkManager/private-dhcp.

*****  Plugin catchall (100. confidence) suggests   **************************

If vous pensez que nm-dhcp-helper devrait être autorisé à accéder connectto sur private-dhcp unix_stream_socket par défaut.
Then vous devriez rapporter ceci en tant qu'anomalie.
Vous pouvez générer un module de stratégie local pour autoriser cet accès.
autoriser cet accès pour le moment en exécutant :
# grep nm-dhcp-helper /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Looks like the latest batch of updates fixed the problem. Sorry for the noise.
