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.

The output didn't specify if the default for --cname/--search/--legend and
other options was yes or no. Change the description to be explicit about that.
Also make the --help output and man page closer.
|
|
I think example output allows the reader of the man page to
see what functionlity is provided without running the commands
themselves. Specific values in the examples are bound to get out
of date but this is not a problem.

remove bus-proxyd
|
|
It has fairly wide functionality now and the interface has been
stable for a while. It it a useful testing tool.
The name is changed to better indicate what it does.
|
|
Previous code only allowed a single name to be passed, and duplicated
it over all descriptors. For the sake of testing, allow different
names and in arbitrary number. If just one is given, duplicate it
to match the number of sockets. This matches previuos behaviour.
Since this is a testing tool, it seems useful to allow passing invalid
names to test application behaviour with invalid names. Hence, only
warn. When warning, escape the name.
|
|
Some spring cleaning
|
|
The setting is hardly useful (since its effect is generally reduced to zero due
to file system caps), and with the advent of ambient caps an actually useful
replacement exists, hence let's get rid of this.
I am pretty sure this was unused and our man page already recommended against
its use, hence this should be a safe thing to remove.
|
|
Better support of OPENPGPKEY, CAA, TLSA packets and tests
|
|
As kdbus won't land in the anticipated way, the bus-proxy is not needed in
its current form. It can be resurrected at any time thanks to the history,
but for now, let's remove it from the sources. If we'll have a similar tool
in the future, it will look quite differently anyway.
Note that stdio-bridge is still available. It was restored from a version
prior to f252ff17, and refactored to make use of the current APIs.

Remove kdbus custom endpoint support

This feature will not be used anytime soon, so remove a bit of cruft.
The BusPolicy= config directive will stay around as compat noop.

The "is-enabled" command doesn't care whether the symlinks are declared in the
[Install] section of a unit file or not, when returning "enabled". Any alias,
.wants/ or .requires/ symlinks suffice.

cgroup: remove support for NetClass= directive
|
|
Support for net_cls.class_id through the NetClass= configuration directive
has been added in v227 in preparation for a per-unit packet filter mechanism.
However, it turns out the kernel people have decided to deprecate the net_cls
and net_prio controllers in v2. Tejun provides a comprehensive justification
for this in his commit, which has landed during the merge window for kernel
v4.5:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=bd1060a1d671
As we're aiming for full support for the v2 cgroup hierarchy, we can no
longer support this feature. Userspace tool such as nftables are moving over
to setting rules that are specific to the full cgroup path of a task, which
obsoletes these controllers anyway.
This commit removes support for tweaking details in the net_cls controller,
but keeps the NetClass= directive around for legacy compatibility reasons.

Corrects an incompatibility introduced with 36c16a7cdd6c33d7980efc2cd6a2211941f302b4.
Fixes: #2537
|

Previously, using --accept would enable inetd-style socket activation in addition to per-connection operation. This is
now split into two switches: --accept only switches between per-connection or single-instance operation. --inetd
switches between inetd-style or new-style fd passing.
This breaks the interface of the tool, but given that it is a debugging tool shipped in /usr/lib/systemd/ it's not
really a public interface.
This change allows testing new-style per-connection daemons.

Fix for #2467

unit, not just services
This moves the StartLimitBurst=, StartLimitInterval=, StartLimitAction=, RebootArgument= from the [Service] section
into the [Unit] section of unit files, and thus support it in all unit types, not just in services.
This way we can enforce the start limit much earlier, in particular before testing the unit conditions, so that
repeated start-up failure due to failed conditions is also considered for the start limit logic.
For compatibility the four options may also be configured in the [Service] section still, but we only document them in
their new section [Unit].
This also renamed the socket unit failure code "service-failed-permanent" into "service-start-limit-hit" to express
more clearly what it is about, after all it's only triggered through the start limit being hit.
Finally, the code in busname_trigger_notify() and socket_trigger_notify() is altered to become more alike.

This is similar how we already do it for logind or machined.
|
|
Build sys and man fixes
|
|
Just a clarification. At least systemd-openqa-generator from
openqa gets this wrong.
|
|
Saying it is the "default" is misleading, because it is almost
never used.
|
|
All distribution-specific code was removed ages ago.
|
|
This makes sure we never run two control processes at the same time, we cannot keep track off.
This introduces a slight change of behaviour but cleans up the definition of ExecStop= and ExecStopPost=. The former is
now invoked only if the service managed to start-up correctly. The latter is called even if start-up failed half-way.
Thus, ExecStopPost= may be used as clean-up step for both successful and failed start-up attempts, but ExecStop='s
purpose is clearly defined as being responsible for shutting down the service and nothing else.
The precise behaviour of this was not documented yet. This commit adds the necessary docs.
Fixes: #1254

This adds a new switch --as-pid2, which allows running commands as PID 2, while a stub init process is run as PID 1.
This is useful in order to run arbitrary commands in a container, as PID1's semantics are different from all other
processes regarding reaping of unknown children or signal handling.

journalctl: add match for the current boot when called with devpath (v2)

journalctl --fields logic
|

|

Fixes #2176
|
|
This adds two new calls to get the list of all journal fields names currently in use.
This is the low-level support to implement the feature requested in #2176 in a more optimized way.
