2016-06-10networkd: fix dbus matchmac interface (#3485)Andrew Jeddeloh
Fix issue where the *Network passed via userdata is being offset by offsetof(Network, matchmac) leading to incorrect values being exposed in dbus.

2016-06-09networkd: clean up vlan handling a bit (#3478)Lennart Poettering
Let's add a generic parser for VLAN ids, which should become handy as preparation for PR #3428. Let's also make sure we use uint16_t for the vlan ID type everywhere, and that validity checks are already applied at the time of parsing, and not only whne we about to prepare a netdev. Also, establish a common definition VLANID_INVALID we can use for non-initialized VLAN id fields.
2016-06-09bus_util: add support to map double (#3479)Susant Sahani

it (#3457) Let's add an extra safety check before we chmod/chown a TTY to the right user, as we might end up having connected something to STDIN/STDOUT that is actually not a TTY, even though this might have been requested, due to permissive StandardInput= settings or transient service activation with fds passed in.

2016-06-07networkd: rename IPv6AcceptRouterAdvertisements to IPv6AcceptRALennart Poettering
The long name is just too hard to type. We generally should avoid using acronyms too liberally, if they aren't established enough, but it appears that "RA" is known well enough. Internally we call the option "ipv6_accept_ra" anyway, and the kernel also exposes it under this name. Hence, let's rename the IPv6AcceptRouterAdvertisements= setting and the [IPv6AcceptRouterAdvertisements] section to IPv6AcceptRA= and [IPv6AcceptRA]. The old setting IPv6AcceptRouterAdvertisements= is kept for compatibility with older configuration. (However the section [IPv6AcceptRouterAdvertisements] is not, as it was never available in a published version of systemd.

2016-06-07sd-netlink: fix deep recursion in message destruction (#3455)David Herrmann
On larger systems we might very well see messages with thousands of parts. When we free them, we must avoid recursing into each part, otherwise we very likely get stack overflows. Fix sd_netlink_message_unref() to use an iterative approach rather than recursion (also avoid tail-recursion in case it is not optimized by the compiler).

2016-06-06mount: make sure got into MOUNT_DEAD state after a successful umount (#3444)michaelolbrich
Without this code the following can happen: 1. Open a file to keep a mount busy 2. Try to stop the corresponding mount unit with systemctl -> umount fails and the failure is remembered in mount->result 3. Close the file and umount the filesystem manually -> mount_dispatch_io() calls "mount_enter_dead(mount, MOUNT_SUCCESS)" -> Old error in mount->result is reused and the mount unit enters a failed state Clear the old error result when 'mountinfo' reports a successful umount to fix this.
2016-06-06network: beef up ipv6 RA support considerablyLennart Poettering
This reworks sd-ndisc and networkd substantially to support IPv6 RA much more comprehensively. Since the API is extended quite a bit networkd has been ported over too, and the patch is not as straight-forward as one could wish. The rework includes: - Support for DNSSL, RDNSS and RA routing options in sd-ndisc and networkd. Two new configuration options have been added to networkd to make this configurable. - sd-ndisc now exposes an sd_ndisc_router object that encapsulates a full RA message, and has direct, friendly acessor functions for the singleton RA properties, as well as an iterative interface to iterate through known and unsupported options. The router object may either be retrieved from the wire, or generated from raw data. In many ways the sd-ndisc API now matches the sd-lldp API, except that no implicit database of seen data is kept. (Note that sd-ndisc actually had a half-written, but unused implementaiton of such a store, which is removed now.) - sd-ndisc will now collect the reception timestamps of RA, which is useful to make sd_ndisc_router fully descriptive of what it covers. Fixes: #1079

2016-06-06lldp: deal properly with recv() returning EAGAIN/EINTRLennart Poettering
It might very well return EAGAIN in case of packet checksum problems and suchlike, hence let's better handle this nicely, the same way as we do it in the other sd-network libraries for incoming datagrams.
2016-06-06lldp: pass correct neighbor object to REMOVED callbackLennart Poettering
2016-06-06lldp: rename TLV accessor pseudo-macrosLennart Poettering
Let's make sure the inline functions for retrieving TLV data actually carry TLV in the name, so that we don#t assume they retrieve the whole, raw packet data.
2016-06-06lldp: make sd_lldp_neighbor_tlv_rewind() return whether there's a first entryLennart Poettering
This way it's nicer to use as it matches how sd_lldp_neighbor_tlv_next() indicates an EOF too via its return value.

setting the ifindex Let's make sd-lldp a bit more like sd-ndisc ant the other APIs, and add proper ref counting and a separate call for setting the ifindex. This also adds a new lldp_reset() call we can use at various places to close all fds. This is also similar to how sd-ndisc already does it.

2016-06-06sd-lldp: take triple timestamp when reading LLDP packetsLennart Poettering
It's a good idea to store away the recption time of LLDP packets in the neighbor object, simply because the LLDP data only has a validity of a certain amount of time. Hence, let's record the timestamp when we receive the datagram and expose an API for it. Also, automatically expire LLDP neighbors based on this new timestamp.
2016-06-06sd-event: port over to new triple timestamp logicLennart Poettering
2016-06-06time-util: add triple timestamp objectLennart Poettering
We already have a double timestamp object that we use whenever we need both a MONOTONIC and a REALTIME timestamp taken and stored. With this change we also add a triple timestamp object that in addition stores a BOOTTIME timestamp, which is useful for a few usecases. Note that we keep dual_timestamp around, as it is useful in many cases where triple_timestamp is not, in particular because retrieving the monotonic and realtime timestamps is much cheaper on Linux that getting the boottime timestamp.
2016-06-06resolved: also rewrite private /etc/resolv.conf when configuration is ↵Lennart Poettering
changed via bus calls This also moves log message generation into manager_write_resolv_conf(), so that it is shorter to invoke the function, given that we have to invoke it at a couple of additional places now. Fixes: #3225
2016-06-06resolved: support IPv6 DNS servers on the local linkLennart Poettering
Make sure we can parse DNS server addresses that use the "zone id" syntax for local link addresses, i.e. "fe80::c256:27ff:febb:12f%wlp3s0", when reading /etc/resolv.conf. Also make sure we spit this out correctly again when writing /etc/resolv.conf and via the bus. Fixes: #3359

2016-06-05automount: handle expire_tokens when the mount unit changes its state (#3434)michaelolbrich
This basically reverts 7b2fd9d51259f6cf350791434e640ac3519acc6c ("core: remove duplicate code in automount_update_mount()"). This was not duplicate code. The expire_tokens need to be handled as well: Send 0 == success for MOUNT_DEAD (umount successful), do nothing for MOUNT_UNMOUNTING (not yet done) and an error for everything else. Otherwise the automount logic will assume unmounting is not done and will not send any new requests for mounting. As a result, the corresponding mount unit is never mounted. Without this, automounts with TimeoutIdleSec= are broken. Once the idle timeout triggered a umount, any access to the corresponding filesystem hangs forever. Fixes #3332.
