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
2016-06-06network: use inet_ntop() rather than SD_NDISC_ADDRESS_FORMAT_VAL() when ↵Lennart Poettering
serializing Let's use the usual libc API for serializing IPv6 addresses, instead of the NDISC-specific macro we should get rid of anyway.

2016-06-06lldp: include sys/types.h in sd-lldp.hLennart Poettering
After all, we use clockid_t which is defined there.
2016-06-06lldp: minor coding style improvementLennart Poettering
2016-06-06lldp: add sd_lldp_get_event() callLennart Poettering
sd-ndisc has something like this, let's add this for sd-lldp, too.
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.
2016-06-06lldp: use NULL instead 0, when we deal with a pointerLennart Poettering
2016-06-06lldp: add _public_ to a two exported functions missing itLennart Poettering
2016-06-06lldp: clarify that sd_lldp_neighbor_get_ttl() returns secondsLennart Poettering
Let's simply encode this in the parameter name.
2016-06-06lldp: add proper ref counting to sd_lldp object and a separate call for ↵Lennart Poettering
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.
2016-06-06exit-code: minor coding style updatesLennart Poettering
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.

2016-06-05automount: 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.

core: log cgroup legacy and unified hierarchy setting translations
2016-06-03core: always use "infinity" for no upper limit instead of "max" (#3417)Tejun Heo
Recently added cgroup unified hierarchy support uses "max" in configurations for no upper limit. While consistent with what the kernel uses for no upper limit, it is inconsistent with what systemd uses for other controllers such as memory or pids. There's no point in introducing another term. Update cgroup unified hierarchy support so that "infinity" is the only term that systemd uses for no upper limit.

2016-06-03resolved: fix comments in resolve.conf for search domain overflows (#3422)Martin Pitt
Write comments about "too many search domains" and "Total length of all search domains is too long" just once. Also put it on a separate line, as resolv.conf(5) only specifies comments in a line by themselves. This is ugly to do if write_resolv_conf_search() gets called once for every search domain. So change it to receive the complete OrderedSet instead and do the iteration by itself. Add test cases to networkd-test.py. https://launchpad.net/bugs/1588229
2016-06-03hwdb: Add Thinkpad X1 carbon 4th gen to 70-pointingstick.hwdb (#3426)Matthieu Codron
Like many other recent thinkpads the factory default pointingstick sensitivity on these devices is quite low, making the pointingstick very slow in moving the cursor. This extends the existing hwdb rules for tweaking the sensitivity to also apply to the X1 carbon 4thgen model.
2016-06-02core: log cgroup legacy and unified hierarchy setting translationsTejun Heo
To accommodate changes in kernel interface, cgroup unified hierarchy support added several configuration items which overlap with the existing resource control settings and there is simple config translation between the overlapping settings to ease the transition. As why certain cgroup knobs are being configured can become confusing, this patch adds a master warning message which is printed once when such translation is first used and logs each translation with a debug message. v2: - Switched to log_unit*().
2016-06-02core: pass Unit into cgroup_context_apply() and use log_unit*()Tejun Heo
cgroup_context_apply() and friends take CGroupContext and cgroup path as input and has no way of getting back to the associated Unit and thus uses raw cgroup path for logging. This makes the log messages difficult to track down. There's no reason to avoid passing in Unit into these functions. Pass in Unit and use log_unit*() instead. While at it, make cgroup_context_apply(), which has no outside users, static. Also, drop cgroup path from log messages where the path itself isn't too interesting and can be easily obtained from the unit.
2016-06-02networkd-ndisc: do not start DHCPv6 when after NDISC timeoutTom Yan
For it's silly and unnecessary. Although it was apparently mandated by RFC 2462 in [5.5.2. Absence of Router Advertisements], that has been changed in the same section of RFC 4862, which obsoleted the former RFC.

2016-06-01units: wait for plymouth to shut down in rescue.sevice (#3367)Franck Bui
In the same vein as commit ac59f0c12c117b9bb5b7e17f33987b0107791239 which added the --wait option to the emergency service, this patch makes sure that plymouth has exited before entering into the rescue mode.
2016-06-01networkd-dhcp6: generalize DHCPv6 client (re)startingTom Yan
dhcp6_request_address() was merely a function to switch the DHCPv6 client from "stateless" mode to "stateful" mode. It was also a one-way switch. Also, to (re)start the client, we would need to repeat separate function calls. In this patch, dhcp6_request_address() is made a general starter/manager of the DHCPv6 client. It now takes an extra parameter so we will be specifying which mode the DHCPv6 client should be started in. Also it will keep track of the current mode and compare with the newly requested mode, and only restart the client in case there is a difference between them. This also makes sure that the DHCPv6 client will be (re)started accordingly as per the Router Advertisement flags.
