platform: fix crash if link has no name after 5e935dfd

2014-03-14T20:58:41+00:00

When a VPN goes down, like at suspend, and the link has already
disappeared, the new platform logging code tries to print the
link information using a link object with only the ifindex filled
in.  When adding/removing/changing links, internal code often fills
in just the ifindex (becuase that's all you need).  Thus
to_string_link() will always fail if that operation fails.

    at platform/nm-linux-platform.c:688
    at platform/nm-linux-platform.c:1835
    at vpn-manager/nm-vpn-connection.c:274

Work around that for now and live with the warnings until
we decide what to actually do about to_string_link().

platform: fix link_type_from_udev() to use ifname from libnl

2014-03-12T15:58:19+00:00

When an interface gets renamed, we first receive a libnl update with
the changed interface name.

This results in the following chain of calls:
  - event_notification()
  - announce_object()
  - link_init()
  - link_extract_type()
  - link_type_from_udev()
Then link_type_from_udev() looks up the name in the udev data (getting
the previous name, because we did not yet recieve the udev notification)
and passes the name to wifi_utils_is_wifi(), which eventually calls
nm_platform_link_get_ifindex() -- doing a lookup by the old name.

Fix this, by passing the ifname from libnl to link_type_from_udev().

Also, change hack_empty_master_iff_lower_up() because it is called
from event_notification(), at a moment when the link cache possibly
does not yet know the ifindex -- so that the call chain to
link_extract_type(), link_type_from_udev(), wifi_utils_is_wifi()
again might lead to lookup for something that does not yet exist.
Note, that in this case the name would not yet exist, because we
did not yet put the libnl object into the link cache.

platform, devices: add support for vxlan devices

2014-03-06T14:48:15+00:00

Since vxlan is new-ish, and vxlan IPv6 support in particular has only
been in the kernel since 3.11, we include our own copy of the vxlan
netlink constants rather than depending on the installed headers.
