tree-wide: merge pager_open_if_enabled() to the pager_open()
2016-02-26tree-wide: merge pager_open_if_enabled() to the pager_open()Alexander Kuleshov
Many subsystems define own pager_open_if_enabled() function which checks '--no-pager' command line argument and open pager depends on its value. All implementations of pager_open_if_enabled() are the same. Let's merger this function with pager_open() from the shared/pager.c and remove pager_open_if_enabled() from all subsytems to prevent code duplication.

2016-02-22tree-wide: make ++/-- usage consistent WRT spacingVito Caputo
Throughout the tree there's spurious use of spaces separating ++ and -- operators from their respective operands. Make ++ and -- operator consistent with the majority of existing uses; discard the spaces.

See: #2683
2016-02-21sd-lldp: beef up callback logicLennart Poettering
Instead of just notifying about the fact that something changed in the database, actually inform the callback what precisely changed. This is useful, so that the LLDP tx logic can be put into "fast" mode as soon as a previously unknown peer appears, as suggested by the LLDP spec.

2016-02-21networkctl: add missing newline to printf() format stringLennart Poettering
2016-02-21networkd: add basic LLDP transmission supportLennart Poettering
Let's add some minimalistic LLDP sender support. The idea is that this is either on or off, and all fields determined automatically rather than configured explicitly.
2016-02-21sd-lldp: filter out LLDP messages coming from our own MAC addressLennart Poettering
Let's not get confused should we be connected to some bridge that mirrors back our packets.
2016-02-21networkd: make a couple of functions staticLennart Poettering
These functions are nowadays used only within networkd-link.c, hence ther's no point in littering our public namespace with them.
2016-02-21networkd: rework when LLDP reception is enabledLennart Poettering
Being on the link-layer LLDP is nothing we should turn on only when there's a link beat. Instead, turn it on, whenever the iface is UP regardless if there's a link beat or not. This closes the race between a link beat being available and us subscribing to LLDP as a result.
2016-02-21networkctl: print a nice warning when networkd isn't runningLennart Poettering
2016-02-21networkctl: if there's no data from networkd about an iface show as "unmanaged"Lennart Poettering
After all, if we know that an interface exists but networkd did not store any info about it, then it's definitely unmanaged by it. (Note that we add this fix-up to networkctl, and not to sd-network, simply because a missing file might also be result of the interface not existing.)
2016-02-21networkctl: add a couple of (void) castsLennart Poettering
Where we knowingly ignore possible error results, let's cast to void.
2016-02-21networkd: rework how carrier bindings are serializedLennart Poettering
Instead of serializing the interface name, expose the interface index, since that's the only stable identifier.
2016-02-21networkd: turn on LLDP reception by default, in "routers-only" modeLennart Poettering
This way "networkctl status" becomes a bit more useful by default, as router information is just visible, without any further configuration. LLDP reception is fully passive and relatively low simple and low traffic, hence this should be safe to enable by default.
2016-02-21networkctl: extend "networkctl status" per-interface output to include LLDP infoLennart Poettering
This adds a small and useful field to the "systemctl status" output: the router(s) the interface is connected to as reported via LLDP. Example output: ● 2: enp0s25 Link File: /usr/lib/systemd/network/99-default.link Type: ether State: degraded (configured) Path: pci-0000:00:19.0 Driver: e1000e Connected To: GS1900 on port 2 (foobar) i.e. the last line is the relevant one.
2016-02-21networkctl: make use of xsprintf() where we canLennart Poettering
2016-02-21networkctl: simplify networkctlLennart Poettering
Move decode_and_sort_links() into acquire_info_all() which is the only place this is used. The result is then nicely symmetric to acquire_info_strv().
2016-02-21networkctl: rework interface data acquisitionLennart Poettering
Let's always use the same calls to acquire interface data. Specifically port "networkctl status" to use acquire_link_info_strv() and acquire_link_info_all() like the other calls.
2016-02-21networkctl: extend "networkctl list" and "networctl lldp" to optionally take ↵Lennart Poettering
interface names This way, the output may be reduced to only show data about the specified interfaces.

2016-02-21sd-lldp: rework sd-lldp APILennart Poettering
This reworks the sd-lldp substantially, simplifying things on one hand, and extending the logic a bit on the other. Specifically: - Besides the sd_lldp object only one other object is maintained now, sd_lldp_neighbor. It's used both as storage for literal LLDP packets, and for maintainging info about peers in the database. Separation between packet, TLV and chassis data is not maintained anymore. This should be a major simplification. - The sd-lldp API has been extended so that a couple of per-neighbor fields may be queried directly, without iterating through the object. Other fields that may appear multiple times, OTOH have to be iterated through. - The maximum number of entries in the neighbor database is now configurable during runtime. - The generation of callbacks from sd_lldp objects is more restricted: callbacks are only invoked when actual data changed. - The TTL information is now hooked with a timer event, so that removals from the neighbor database due to TTLs now result in a callback event. - Querying LLDP neighbor database will now return a strictly ordered array, to guarantee stability. - A "capabilities" mask may now be configured, that selects what type of LLDP neighbor data is collected. This may be used to restrict collection of LLDP info about routers instead of all neighbors. This is now exposed via networkd's LLDP= setting. - sd-lldp's API to serialize the collected data to text files has been removed. Instead, there's now an API to extract the raw binary data from LLDP neighbor objects, as well as one to convert this raw binary data back to an LLDP neighbor object. networkd will save this raw binary data to /run now, and the client side can simply parse the information. - support for parsing the more exotic TLVs has been removed, since we are not using that. Instead there are now APIs to extract the raw data from TLVs. Given how easy it is to parse the TLVs clients should do so now directly instead of relying on our APIs for that. - A lot of the APIs that parse out LLDP strings have been simplified so that they actually return strings, instead of char arrays with a length. To deal with possibly dangerous characters the strings are escaped if needed. - APIs to extract and format the chassis and port IDs as strings has been added. - lldp.h has been simplified a lot. The enums are anonymous now, since they were never used as enums, but simply as constants. Most definitions we don't actually use ourselves have eben removed.

2016-02-20tree-wide: place #pragma once at the same place everywhereLennart Poettering
Usually, we place the #pragma once before the copyright blurb in header files, but in a few cases we didn't. Move those around, so that we do the same thing everywhere.
2016-02-20sd-lldp: drop "port" objectLennart Poettering
Let's just keep the few parts we actually need of it in the main sd_lldp object, so that we can simplify things quite a bit. While we are at it, remove ifname and mac fields which we make no use of whatsoever.

2016-02-16networkd: rework idle detection logic of networkdLennart Poettering
This patch makes networkd stay around as long as there is more than just a loopback interface around, or the loopback device isn't fully probed yet, or the loopback device has a .network file attached. In essence, this means networkd stays around now continously as it should, unless it is running in some (container?) environment that really has no interface except a loopback device. Fixes #2577.

2016-01-26util: introduce fputs_with_space() and make use of it at various placesLennart Poettering
The call combines outputing a string with prefixing it with a space, optionally. This is useful to shorten the logic for outputing lists of strings, that are space separated.
2016-01-26networkd: optinally use DHCP lease domain info for routing onlyLennart Poettering
This changes the UseDomains= setting of .network files to take an optional third value "route", in addition to the boolean values. If set, the passed domain information is used for routing rules only, but not for the search path logic.
2016-01-26networkd: rename a few Network object properties to be more like the ↵Lennart Poettering
configuration settings All booleans called dhcp_xyz are now called ".dhcp_use_xyz", to match their respective configuration file settings. This should clarify things a bit, in particular as there is a DHCP hostname that was previously called just ".hostname" because ".dhcp_hostname" was already existing as a bool. Since this confusion is removed now because the bool is called ".dhcp_use_hostname", the string field is now renamed to ".dhcp_hostname".
2016-01-26networkd: when filtering out duplicate domain names use DNS comparisonLennart Poettering
When we collect the domain names of the various links and other sources in one ordered set, make sure to use proper DNS name comparison to filter out duplicates.
2016-01-26networkd: use an OrderedSet instead of Set to collect link domainsLennart Poettering
For the search domain logic the order is highly relevant, hence make sure when collecting the various search domains to add them to an ordered set, so that the order between search domains of a specific link is retained.
2016-01-26networkctl: move strv_isempty() check into dump_list()Lennart Poettering
Previously, each invocation of dump_list() was prefixed with a call to strv_isempty() to suppress invocation of the function when the list is empty anyway. Move the check into the function itself, so that we can reduce the code a bit in size. (Also, prefix a couple of invocations we knowingly ignore return errors with a (void) cast).
2016-01-26networkd: rework Domains= settingLennart Poettering
Previously, .network files only knew a vaguely defined "Domains=" concept, for which the documentation declared it was the "DNS domain" for the network connection, without specifying what that means. With this the Domains setting is reworked, so that there are now "routing" domains and "search" domains. The former are to be used by resolved to route DNS request to specific network interfaces, the latter is to be used for searching single-label hostnames with (in addition to being used for routing). Both settings are configured in the "Domains=" setting. Normal domain names listed in it are now considered search domains (for compatibility with existing setups), while those prefixed with "~" are considered routing domains only. To route all lookups to a specific interface the routing domain "." may be used, referring to the root domain. An alternative syntax for this is the "*", as was already implemented before using the "wildcard" domain concept. This commit adds proper parsers for this new logic, and exposes this via the sd-network API. This information is not used by resolved yet, this will be added in a later commit.
