On some systems with python-libselinux a bug[1] related to recursive
restorecon fails but the distro release does not yet include
an update. This change will accept the error and log a warning.
On systems with selinux enabled, some of the networking commands executed
successfully do not return 0. Allow these commands to return 1 since the
output is valid.
Ultimately we need to get this information in some way so that we can
display it correctly. For now, work around the stack trace when selinux
does not allow us to collect it.
In cases where the config json specifies nameserver entries,
if there are interfaces configured to use dhcp, NetworkManager,
if enabled, will clobber the /etc/resolv.conf that cloud-init
has produced, which can break dns. If there are no interfaces
configured to use dhcp, NetworkManager could clobber
/etc/resolv.conf with an empty file.
This patch adds a mechanism for dropping additional configuration
into /etc/NetworkManager/conf.d/ and disables management of
/etc/resolv.conf by NetworkManager when nameserver information is
provided in the config.
Use distro release version to determine if we use systemd in redhat spec
The typical rpm build process will examine the spec file to determine
which packages should be installed in the boot root. This requires
the specfile to declare that it needs system. Provide this information
by checking which version in which the rpm is being built and exporting
requirements for systemd.
The network_state object's network and route keys would have different
information depending upon how the network_state object was populated.
This change cleans that up. Now:
* address will always contain an IP address.
* prefix will always include an integer value that is the
network_prefix for the address.
* netmask will be present only if the address is ipv4, and its
value will always correlate to the 'prefix'.
