Lennart Poettering d3cf48f4bd networkd: run as unpriviliged "systemd-network" user 
This allows us to run networkd mostly unpriviliged with the exception of
CAP_NET_* and CAP_SYS_MODULE. I'd really like to get rid of the latter
though...

Tom Gundersen 68baa8faf3 sd-network: avoid false positive compiler warning caused by LTO 
Djalal Harouni <tixxdz@opendz.org>:
There is also this one genrated by LTO, IMO it's a false positive since
we do *check* for "lease" but the code is not consistent since in that
code path, "lease" is initialized to NULL in other places, except for
this one:

src/resolve/resolved-manager.c: In function 'manager_update_resolv_conf':
src/libsystemd-network/sd-dhcp-lease.c:67:18: warning: 'lease' may be used uninitialized in this function [-Wmaybe-uninitialized]
        if (lease->dns_size) {
                 ^
src/network/sd-network.c:146:24: note: 'lease' was declared here
        sd_dhcp_lease *lease;
                       ^

Lennart Poettering 19befb2d5f sd-bus: introduce sd_bus_slot objects encapsulating callbacks or vtables attached to a bus connection 
This makes callback behaviour more like sd-event or sd-resolve, and
creates proper object for unregistering callbacks.

Taking the refernce to the slot is optional. If not taken life time of
the slot will be bound to the underlying bus object (or in the case of
an async call until the reply has been recieved).

Susant Sahani 7951dea209 networkd: introduce ipip tunnel 
This patch enables basic ipip tunnel support.
It works with kernel module ipip

example conf:

file: ipip.netdev

[NetDev]
Name=ipip-tun
Kind=ipip
MTUBytes=1480

[Tunnel]
Local=192.168.223.238
Remote=192.169.224.239
TTL=64

file: ipip.network

[Match]
Name=em1

[Network]
Tunnel=ipip-tun

Tom Gundersen 2e9f08eaf1 networkd: listen for address changes 
This is proof-of-concept only, as we only log the changes but don't do anything
with it.

Tom Gundersen 897e184c7d rtnl: change from bitmask to enum for rtnl groups 
The bitmask is deprecated in the kernel, so move to the new interface. At the moment
this does not make a difference for us, but it avoids having to change the API in the future.

Tom Gundersen 389cc5f743 networkd: link - redo flag change logging 
Make the logging less verbose by only printing all the changed flags on one line,
at the same time make it more complete by supporting all flags currently supported
by the kernel.

We still fall back to printing the raw flags in case we get something we do not recognize
This may be useful when running on new kernels.

We were ignoring the wrong errno.

Tom Gundersen 7619683b46 networkd: link - handle links coming back to life 
When enslaving devices, we may receieve DELLINK/NEWLINK for the same ifindex,
let's not be confused by this.

Tom Gundersen d9c67ea112 networkd: reorder bonding and bridging 
A link should only ever be part of one, but if we accidentally do both, let's do it
in the right order so the failure is more obvious in the logs.
 2014-05-09 14:41:27 +02:00
Tom Gundersen f22364691b networkd: manager - drop links and netdevs when we receive DELLINK 2014-05-09 14:41:27 +02:00
Tom Gundersen 37ebeb77cf networkd: netdev - drop if creation fails 
This ensures that all links waiting to be enslaved are notified that the netdev does not exist.

Tom Gundersen 370e9930c3 networkd: link - introduce LINGER state and link_drop()
