Handling of /etc/hosts is highly site- and admin- specific in
many more complex cases, and it's exceedingly hard and error-
prone for NetworkManager to handle all those cases. So remove
this functionality entirely. That's not a big loss, as it
turns out there's a much more elegant solution.
The only requirement is that the machine's hostname map back
to an IP address owned by the machine. That requirement can
be satisifed by nss-myhostname or even possibly the distro's
installer. If the user does not want nss-myhostname then it
can be uninstalled. Distros should use a "recommends" feature
in their packaging system so that the NetworkManager package
does *not* have a hard requirement on nss-myhostname. Thus
everyone is happy; things Just Work when nss-myhostname is
installed, but more advanced users can uninstall it and
customize /etc/hosts as they wish.
Another alternative is a dispatcher script that listents for
the 'hostname' event, and updates /etc/hosts according to the
administrator's preference.
When split DNS is used for a local caching nameserver, make sure
that reverse DNS queries for hosts within the VPN tunnel are directed
to the VPN's nameservers, not to the public upstream nameservers.
RFC6101 adds the DNS Search List option to router advertisements. This
allows stateless configuration of suffixes to try when doing DNS lookups.
Make sure we catch these when provided by the kernel and reconfigure
things appropriately.
NOTE: this commit depends on a kernel patch:
http://marc.info/?l=linux-netdev&m=129216173321352&w=2
RFC5006/RFC6106 specifies fairly clearly how to handle multiple RDDNS options.
Unfortunately the previous code didn't deal with this and hence would
misbehave in all but the simplest setups. The new code should be fully
compliant with the following exceptions:
- Router lifetime not respected
- No "sufficient number" management.
- DHCPv6 servers might not be prioritised over RDDNS ones.
We only want to prevent regression to > READY after READY has
been reached, since the interface state will track the supplicant
connection state which legitimately jumps around.
If we find a "iface ..." line, add the interface to
well_known_interfaces no matter if there is a connection for it or not.
Otherwise we fail to mark devices as unmageded in cases like
iface wlan0 inet manual
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
as NM does not know how to parse such a interface configuration.
Bug-Debian: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=569215
This branch now requires wpa_supplicant 0.7 or later with the new
D-Bus interface enabled. It also prefers the "nl80211" supplicant
driver over the WEXT one, but will ask the supplicant to fall back
to the WEXT driver if the device in question does not support the
kernel's nl80211/cfg80211 stack.
If the supplicant cannot be service activated, wait until it shows up
on the bus instead of sitting around doing nothing. This fixes a small
regression introduced when the _READY state was added to the supplicant
interface object.
Don't emit "unmanaged-specs-changed" signal in read_one_connection(),
because it causes that next connections are not listed (get_connections() is
called prematurely and only connections read so far are available).
Steps to reproduce the bug:
1) create ifcfg-fake
DEVICE=loremipsum
HWADDR=01:02:03:04:05:06
NM_CONTROLLED=no
2) restart NetworkManager
3) only connections read *before* ifcfg-fake are available
Thanks to Robert Vogelgesang <vogel@users.sourceforge.net> for updating
the patch and analysis!
GATEWAY0=0.0.0.0 was erroneously denied. Also, missing GATEWAY0 entry caused
ifcfg-rh plugin to regard the connection as invalid. The commit fixes that and
makes it behave in accordance with initscripts.
Don't bother trying to initialize the user settings proxy when it
isn't even active. Would trigger a warning to syslog if PolicyKit
permissions changed via changes to /usr/share/polkit-1/actions/.
By the time we get the udev device removal notification we may not
be able to read properties, since the device has already been
removed from sysfs. That means we can't get the ifindex, so we need
to fall back to the interface name. But we always want to prefer
the ifindex since that will never change as long as the device is
connected, unlike the interface name.
