2014-04-03networkd: smooth transition from ipv4ll to dhcp addressUmut Tezduyar Lindskog
Currently when both ipv4ll and dhcp are enabled, ipv4ll address (if one has been claimed) is removed when dhcp address is aquired. This is not the best thing to do since there might be clients unaware of the removal trying to communicate. This patch provides a smooth transition between ipv4ll and dhcp. If ipv4ll address was claimed [1] before dhcp, address is marked as deprecated. Deprecated address is still a valid address and packets can be received on it but address cannot be selected as a source address. If dhcp lease cannot be extended, then ipv4ll address is marked as valid again. [1] If there is no collision, claiming IPv4LL takes between 4 to 7 seconds.

2014-04-02logind: don't print error if devices vanish during ACL-initDavid Herrmann
If a device is unplugged while we initialize it, we will get ENOENT for ACL-init (and related stuff). We currently print errors then, which is misleading. Print a debug-message early and continue.

2014-04-02sd-dhcp-client: use BPF on raw socketTom Gundersen
Filter out everything except UDP packets destined for the DHCP client port, this should avoid the vast majority of spurious wakeups. Filter based on [0], with permission. Possible improvemnts: also check for the DHCP magic cookie to drop invalid packets. Check for our xid to filter out packets destined for other clients.

2014-04-01sd-ipv4ll: speed up bind() in the same way as for dhcpTom Gundersen
2014-04-01sd-dhcp-client: --omg-optimizedTom Gundersen
Passing the protocol to socket() is redundant as it will be specified again in bind(). Dropping the redundancy reduces the cost of bind() from ~30ms to ~0ms. For details see [0]. networkd in a container (i.e., with next to no network latency) can now negotiate a DHCP lease in 0.7 - 5 ms. Thanks to Kay for help with debugging and to Daniel Borkmann for the pointer to fix the problem.

2014-03-31networkd: rewind rtnl message between passing it to functionsTom Gundersen
This makes updating link status on netdev links work again.

2014-03-31networkd: fix use-after-freeTom Gundersen
Free networks before links (the reverse of creation order).

2014-03-30sd-dhcp: avoid checksum calculation if possibleTom Gundersen
When receiving lots of packets that are not meant for us, we waste a relatively large amount of cpu time computing their checksums before discarding them. Move the checksum calculation last so we never compute it for packets which would otherwise be discarded.

2014-03-30sd-dhcp: check for udp packetsUmut Tezduyar Lindskog
Do not try to parse ICMP packets [tomegun: slightly tweaked debug message]

2014-03-29sd-rtnl: message - fix clang compile warningTom Gundersen
2014-03-28sd-rtnl: message - don't log about out-of-range attribute typesTom Gundersen
We will easily get these when running on newer kernels. However, we can safely ignore them as we anyway don't know what to do with them.

2014-03-28sd-rtnl: rework rtnl type systemTom Gundersen
Use a static table with all the typing information, rather than repeated switch statements. This should make it a lot simpler to add new types. We need to keep all the type info to be able to create containers without exposing their implementation details to the users of the library. As a freebee we verify the types of appended/read attributes. The API is extended to nicely deal with unions of container types.

2014-03-28sd-rtnl: message - don't reference associated rtnl objectTom Gundersen
The object is not currently used, so just drop the refenence. If/when we end up using the object in the future, we must make sure to deal with possible mutual references between rtnl busses and their queued messages; as is done in sd-bus.
2014-03-27udev: persistent naming - we cannot use virtio numbers as they are not stableTom Gundersen
This reverts commit 8741f2defaf26aafe5ee0fd29954cfdf84ee519c: 'Add virtio-blk support to path_id' and commit e3d563346c4237af23335cc6904e0662efdf62ad: 'udev: net_id - handle virtio buses'. Distros may want to take note of this, as it changes behavior.

Before: $ systemd-analyze --user Startup finished in 2.810s (firmware) + 48ms (loader) + 122ms (userspace) = 122ms After: $ systemd-analyze --user Startup finished in 122ms (userspace) = 122ms

2014-03-25sd-rtnl: add support for tunnel attributesSusant Sahani
Added support for tunneling netlink attrributes (ipip, gre, sit). These works with kernel module ipip, gre and sit . The test cases are moved to a separate file and manual test as well because they require respective kernel modules as well.
2014-03-25sd-rtnl: message - don't try to enter unsupported containersTom Gundersen
Currently we only support containers in RTM_*LINK messages. Reported-by: "Thomas H.P. Andersen <phomes@gmail.com>"

2014-03-24networkd: netdev - fix error handling in set_ifindex()Tom Gundersen
Firstly, remove stray assert(). Also be a bit stricter when verifying the received info. If we get an applicable newlink message that we can't make sense of, we will now enter NETDEV_FAILED, as we cannot reasonably continue without knowing the ifindex of our device.

These tests were both broken and redundant, so let's drop them.

2014-03-24core: remove tcpwrap supportLennart Poettering
tcpwrap is legacy code, that is barely maintained upstream. It's APIs are awful, and the feature set it exposes (such as DNS and IDENT access control) questionnable. We should not support this natively in systemd. Hence, let's remove the code. If people want to continue making use of this, they can do so by plugging in "tcpd" for the processes they start. With that scheme things are as well or badly supported as they were from traditional inetd, hence no functionality is really lost.

2014-03-24service: don't take chkconfig priority into accountLennart Poettering
Given that native services do not carry a sysv priority anyway it is pointless reading them from chkconfig headers, and pretend they'd work. So let's drop this.
