[PATCH net 00/12] net: iflink and link-netnsid fixes
by Sabrina Dubroca
In a lot of places, we use this kind of comparison to detect if a
device has a lower link:
dev->ifindex != dev_get_iflink(dev)
This seems to be a leftover of the pre-netns days, when the ifindex
was unique over the whole system. Nowadays, with network namespaces,
it's very easy to create a device with the same ifindex as its lower
link:
ip netns add main
ip netns add peer
ip -net main link add dummy0 type dummy
ip -net main link add link dummy0 macvlan0 netns peer type macvlan
ip -net main link show type dummy
9: dummy0: <BROADCAST,NOARP> mtu 1500 qdisc noop ...
ip -net peer link show type macvlan
9: macvlan0@if9: <BROADCAST,MULTICAST> mtu 1500 qdisc noop ...
To detect if a device has a lower link, we can simply check the
existence of the dev->netdev_ops->ndo_get_iflink operation, instead of
checking its return value. In particular, I attempted to fix one of
these checks in commit feadc4b6cf42 ("rtnetlink: always put IFLA_LINK
for links with a link-netnsid"), but this patch isn't correct, since
tunnel devices can export IFLA_LINK_NETNSID without IFLA_LINK. That
patch needs to be reverted.
This series will fix all those bogus comparisons, and export missing
IFLA_LINK_NETNSID attributes in bridge and ipv6 dumps.
ipvlan and geneve are also missing the get_link_net operation, so
userspace can't know when those device are cross-netns. There are a
couple of other device types that have an ndo_get_iflink op but no
get_link_net (virt_wifi, ipoib), and should probably also have a
get_link_net.
Sabrina Dubroca (12):
ipvlan: add get_link_net
geneve: add get_link_net
Revert "rtnetlink: always put IFLA_LINK for links with a link-netnsid"
rtnetlink: always put IFLA_LINK for links with ndo_get_iflink
bridge: always put IFLA_LINK for ports with ndo_get_iflink
bridge: advertise IFLA_LINK_NETNSID when dumping bridge ports
ipv6: always put IFLA_LINK for devices with ndo_get_iflink
ipv6: advertise IFLA_LINK_NETNSID when dumping ipv6 addresses
net: link_watch: fix operstate when the link has the same index as the
device
net: link_watch: fix detection of urgent events
batman-adv: fix iflink detection in batadv_is_on_batman_iface
batman-adv: fix detection of lower link in batadv_get_real_netdevice

[PATCH] alfred: notify event listener via unix socket
by Marek Lindner
The alfred server instance accepts event notification registration
via the unix socket. These notification sockets only inform
registered parties of the availibility of an alfred datatype change.
The actual data itself needs to be retrieved via the existing data
retrieval mechanisms.
Unlike the update-command this event monitor allows:
- multiple parallel listeners
- programmatic access to changes without requiring multiple processes
The alfred client allows to monitor events via the newly added '-E'
(event monitor) command line option. Serving as debugging tool and
example code at the same time.

[PATCH] batctl: ping: Skip sleep after last packet
by Sven Eckelmann
The -i option for ping is documented as interval between ping requests. But
the sleep was also applied after all the requested pings already sent out.
As result, the user had to wait additional time until the statistics for
the (limited) ping test was printed.
Just skip the last sleep in case there will be no next ping packet to avoid
this problem.
