2016-02-21github: add a basic issue templateLennart Poettering
As documented here: https://help.github.com/articles/creating-an-issue-template-for-your-repository/
2016-02-21github: move CONTRIBUTING.md into .github subdirectoryLennart Poettering
As suggested by: https://github.com/blog/2111-issue-and-pull-request-templates
2016-02-21man: document the new EmitLLDP= .network settingLennart Poettering
Also, beef up the LLDP documentation a bit.
2016-02-21update TODOLennart Poettering
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: ellipsize long LLDP fields in table outputLennart Poettering
2016-02-21networkctl: add missing newline to printf() format stringLennart Poettering
2016-02-21network: turn on LLDP tx+rx for the default container network configurationLennart Poettering
Containers are relatively trusted and the veth tunnels are small networks, hence let's turn on LLDP both ways for them.
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.
2016-02-21import: don't claim we had copied a settings file if we didn'tLennart Poettering
2016-02-21man: update references to fedora cloud imageLennart Poettering
We are now at F23, hence let's use that as example.
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.)
2016-02-21sd-network: use xsprintf() instead of asprintf() where we canLennart Poettering
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.
2016-02-21networkctl: add new call that unifies link data acquisition between "status" ↵Lennart Poettering
and "lldp" verbs
2016-02-21networkctl: fix dispatch_verb() tableLennart Poettering
VERB_DEFAULT may only appear once.
2016-02-21networkctl: split out system status stuff into its own functionLennart Poettering
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.
2016-02-21udev-rules: use _cleanup_ for fcloseZbigniew Jędrzejewski-Szmek
2016-02-21udev-rules: make error messages about rules more uniformZbigniew Jędrzejewski-Szmek
Also downgrade non-fatal warnings to log_warning. Previously rule_add_key() would check the output array and log a cryptic error and return -1. Most of the time the return value was ignored. This does not seems right, because the buffer can overflow with enough rules. It would also check if we have enough space for the *next* rule, even if there might be not next rule, i.e. off-by-one. Replace this with a check that we have enough space for a next rule before we start parsing. Normally using macros to alter flow is not allowed, but in this case I think it is worth it, because it allows lots of boilerplate code to be removed and hides repeated boring parameters, making function logic much easier to follow.
2016-02-21udev-rules: rewrite function to avoid clobbering argumentsZbigniew Jędrzejewski-Szmek
If the attribute wasn't found, the last filename looked at was returned in the input/output argument. This just seems bad style. The return value was ignored, so change function to return void.
2016-02-21udev-rules: modernize syntax a bitZbigniew Jędrzejewski-Szmek
2016-02-21udev-rules: log_oom() on memory error and abort processing of eventZbigniew Jędrzejewski-Szmek
CID #1313566. Also, change the return value to void, because it is ignored anyway.
2016-02-20sd-device: use (void) before set_iterate callsZbigniew Jędrzejewski-Szmek
set_iterate sets the output argument to NULL on error, and the return value is not used in this case. CID #1306804-09.
2016-02-20time-util: check for overflow in conversion from ts to nsec_tZbigniew Jędrzejewski-Szmek
CID #1320855.

2016-02-20networkd: enable LLDP only on ethernetLennart Poettering
2016-02-20sd-netlink: fix ifi_iftype typeLennart Poettering
The iftype is an unsigned short, and not just an unsigned.
2016-02-20sd-lldp: fix how we create the LLDP listening socketLennart Poettering
Specifiy the ethernet family, and make sure we se the O_CLOEXEC and O_NONBLOCK bits how we should for all fds.
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: simplify lldp_network_bind_raw_socket() a bitLennart Poettering
Let's constify the filter program, drop a few includes and structure definitions.
2016-02-20sd-lldp: move ETHERTYPE_LLDP to missing.hLennart Poettering
After all, most ETHERTYPE variables are defined in the system headers, hence define these where we defined all other fill-ins for system headers.
2016-02-20test-lldp: fix error checking expressionsLennart Poettering
2016-02-20libsystemd-network: sd-event uses 64bit priorities, expose them in the APIs ↵Lennart Poettering
as such
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.
2016-02-20sd-lldp: drop keeping of statisticsLennart Poettering
We don't expose them, and they are only of questionnable use.
