2014-04-11sd-ipv4ll: Add an explicit stop state for IPv4LLPatrik Flykt
Add an explicit stop state for IPv4LL so that the user can stop the IPv4LL client from the callback. When returning from the callback, check also the stop state in order to halt any further protocol processing.
2014-04-11sd-ipv4ll: Add reference counting for IPv4LLPatrik Flykt
Similar to DHCP, the IPv4LL library user can decide to free the LL client any time the callback is called. Guard against freeing the LL client in the callback by introducing proper reference counting. Also update code using the IPv4LL library to properly handle a returned NULL from the notify and stop functions if the IPv4LL client was freed.
2014-04-11sd-dhcp-client: Add an explicit stop state for the DHCP clientPatrik Flykt
Add an explicit stop state for the DHCP client so that the library user can issue a stop at any time the callback has been called. When returning from the callback, check also the stop state and stop any further DHCP processing.
2014-04-11sd-dhcp-client: Add reference counting for DHCPPatrik Flykt
The DHCP library user can decide to free the DHCP client any time the callback is called. After the callback has been called, other computations may still be needed - the best example being a full restart of the DHCP procedure in case of lease expiry. Fix this by introducing proper reference counting. Properly handle a returned NULL from the notify and stop functions if the DHCP client was freed.

2014-04-11sd-rtnl: use SO_PASSCREDTom Gundersen
This unifies the socket handling with other sd-* libraries.

2014-04-10sd-rtnl: don't drop multi-part messagesTom Gundersen
We still only return the first message part in callback/synchronous calls.
2014-04-10sd-rtnl: use GREEDY_REALLOC for message queuesTom Gundersen
2014-04-10sd-dhcp-client: test - fix for jenkinsTom Gundersen
This test should have been updated when changing the magic cookie handling around. Reported by Ken MacLeod.
2014-04-10nspawn: Fix erroneous OOM when building group listPhilip Lorenz
change_uid_gid() never initialises sz which may cause greedy_realloc to skip the initial buffer allocation.
2014-04-10cgls: fix running with -M optionLukas Nykryn
systemd-machined doesn't store cgroup path in a state file anymore. Let's figure it out from the scope.
2014-04-09login: add 'mir' to the list of session typesDavid Herrmann
Add Mir to the list of session types. This is implemented for LightDM in lp:~robert-ancell/lightdm/xdg-session-desktop [1]. [1] https://code.launchpad.net/~robert-ancell/lightdm/xdg-session-desktop/+merge/214108 (david: adjusted commit-header and fixed whitespace issues)

This should never be a problem, but better be safe than sorry.

2014-04-07libsystemd-network: Speed up checksum computation using 64 bit integersTom Gundersen
Improve the checksum computation by using 64 bit integers instead of the 16 bit integers in the existing implementation. This change speeds up the computation with approximately 78% both on 64 bit and 32 bit systems. Please see RFC 1071 for details.
2014-04-07ipv4ll: use BPF on raw socketTom Gundersen
This should significantly reduce spurious wakeups.
2014-04-07sd-ipv4ll: fix packet broadcastingTom Gundersen
Umut said: 'I have noticed a bug that we are sending PROBE/ANNOUNCE messages on 00:00:00:00:00:00 address where it should be broadcast.'
2014-04-06sd-dhcp-client: improve BPFTom Gundersen
Try a bit harder to make the kernel drop packets not for us. This should reduce the number of wakeups from n^2 to n in the number of dhcp clients, which admittedly only makes a differenc in very extreme cases.
2014-04-06sd-dhcp-client: eagerly drop too small packetsTom Gundersen
If they are too small to fit the IP+UDP+DHCP headers they can be of no use, so don't waste resources parsing them. This is at the cost of losing some verbosity in the logging.
2014-04-06sd-dhcp-client: move magic cookie into DHCPMessage structTom Gundersen
Also move the checking of it to the main message handler, rather than the options parser. Fix a bug, so we now drop the packet if any of the magic bytes don't match. Before we used to only drop the packet if they were all wrong.

A parameter which was always null before, now get's set to the module.
2014-04-05systemd-python: use .hex instead of .get_hex()Zbigniew Jędrzejewski-Szmek
It turns out the latter got removed in Python 3. https://bugs.freedesktop.org/show_bug.cgi?id=77086

2014-04-05tty-ask-password-agent: return negative errnoFlorian Albrechtskirchinger
Return negative errno in wall_tty_block(). get_ctty_devnr() already returns a negative errno in case of failure, no need to negate it again. Reported-by: Simon <hwold@odai.homelinux.net>

2014-04-05journal: fix export of messages containing newlinesZbigniew Jędrzejewski-Szmek
In "export" format, newlines are significant, and messages containing newlines must be exported as "binary".

2014-04-04backlight: do nothing if max_brightness is 0Thomas Bächler
On virtually any newer Asus mainboard, the eeepc-wmi driver is loaded. It exposes a backlight device despite the lack of any physical backlight devices. This fake backlight device has max_brightness set to 0. Since the introduction of the clamp_brightness function, systemd-backlight tries to write '1' to brightness and fails. This patch changes systemd-backlight to exit gracefully when max_brightness is 0 before performing any action. This affects both the load and save actions.
2014-04-03sd-rtnl: fix broken test cases and add support for tunnelSusant Sahani
This patch fixes the broken test-cases for sd-rtnl and add support for ipip and sit tunnel. [tomegun: minor fixups]
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.
