priv->ip_iface gets destroyed in vpn_cleanup() when the class
signal handler handles FAILED/DISCONNECTED, but the dispatcher
is only called *after* that, so it gets a NULL ip_iface. Fix that
so that the dispatcher always gets the tunnel interface for
vpn-up and vpn-down.
ifcfg-rh plugin didn't prepend 's:' prefix when writing out ASCII WEP
keys. That rendered the keys file invalid. Moreover, the reading part
was incorrect too not having recognized correct ASCII keys.
dnsmasq may read from its default config file location, which if that
location is a valid config file, it will combine with the options here
and cause undesirable side-effects. Like sending bogus IP addresses
as the gateway or whatever. So give dnsmasq a bogus config file
location to avoid screwing up the configuration we're passing to it.
If the wired setting isn't modified at all from the default values
it won't get written out anymore after 12dcc07b74,
so make sure we include it when necessary.
Since forever we've used sleep/wake as the way to implement
Networking Enabled. When the state file was introduced to make the
networking and wifi states persistent, we ran into a bug where
a failed suspend (like if the machine ran out of power while
suspended) would result in networking being disabled on reboot
since suspend/resume used the same knob as enable/disable.
This patch adds a distinct call for enable/disable networking
which changes the state file, while sleep/wake no longer change
the state file.
All IPv6 enabled sites are expected to provide router advertisement
support apparently. If standalone DHCP is really used in the wild
then we can clearly re-enable it later.
Pad the DNS server expiry somewhat to give a bit of slack in cases
where one RA gets lost or something (which can happen on unreliable
links like wifi where certain types of frames are not retransmitted).
