6e3930c40f smaller journal fixes (#3124)
* sd-journal: detect earlier if we try to read an object from an invalid offset

Specifically, detect early if we try to read from offset 0, i.e. are using
uninitialized offset data.

* journal: when dumping journal contents, react nicer to lines we can't read

If journal files are not cleanly closed it might happen that intermediaery
journal entries cannot be read. Handle this nicely, skip over the unreadable
entries, and log a debug message about it; after all we generally follow the
logic that we try to make the best of corrupted files.

* journal-file: always generate the same error when encountering corrupted files

Let's make sure EBADMSG is the one error we throw when we encounter corrupted
data, so that we can neatly test for it.

* journal-file: when iterating through a partly corruped journal file, treat error like EOF

When we linearly iterate through a corrupted journal file, and we encounter a
read error, don't consider this fatal, but merely as EOF condition (and log
about it).

* journal-file: make seeking in corrupted files work

Previously, when we used a bisection table for seeking through a corrupted
file, and the end of the bisection table was corrupted we'd most likely fail
the entire seek operation. Improve the situation: if we encounter invalid
entries in a bisection table, linearly go backwards until we find a working
entry again.

4706fbaa17 man: don't include history sections in man pages
I am pretty sure we shouldn't carry history sections in man pages, since it's
very hard to keep them correctly updated, the current ones are very
out-of-date, and they tend to make APIs appear unnecessarily complex.

39207373dd systemctl,pid1: do not warn about missing install info with "preset"
When "preset" was executed for a unit without install info, we'd warn similarly
as for "enable" and "disable". But "preset" is usually called for all units,
because the preset files are provided by the distribution, and the units are under
control of individual programs, and it's reasonable to call "preset" for all units
rather then try to do it only for the ones that can be installed.
We also don't warn about missing info for "preset-all". Thus it seems reasonable
to silently ignore units w/o install info when presetting.

(In addition, when more than one unit was specified, we'd issue the warning
only if none of them had install info. But this is probably something to fix
for enable/disable too.)

921f831d3e logind: make KillOnlyUsers override KillUserProcesses
Instead of KillOnlyUsers being a filter for KillUserProcesses, it can now be
used to specify users to kill, independently of the KillUserProcesses
setting. Having the settings orthogonal seems to make more sense. It also
makes KillOnlyUsers symmetrical to KillExcludeUsers.

97e5530cf2 logind: flip KillUserProcesses to on by default
This ensures that users sessions are properly cleaned up after.
The admin can still enable or disable linger for specific users to allow
them to run processes after they log out. Doing that through the user
session is much cleaner and provides better control.

dbus daemon can now be run in the user session (with --enable-user-session,
added in 1.10.2), and most distributions opted to pick this configuration.
In the normal case it makes a lot of sense to kill remaining processes.
The exception is stuff like screen and tmux. But it's easy enough to
work around, a simple example was added to the man page in previous
commit. In the long run those services should integrate with the systemd
users session on their own.

439689c6ec networkd: bump MTU to 1280 for interfaces which have IPv6 enabled (#3077)
IPv6 protocol requires a minimum MTU of 1280 bytes on the interface.
This fixes #3046.

Introduce helper link_ipv6_enabled() to figure out whether IPV6 is enabled.
Introduce network_has_static_ipv6_addresses() to find out if any static
ipv6 address configured.
If IPv6 is not configured on any interface that is SLAAC, DHCPv6 and static
IPv6 addresses not configured, then IPv6 will be automatically disabled for that
interface, that is we write "1" to /proc/sys/net/ipv6/conf//disable_ipv6.

4b743d679b man: try to explain different actions in tmpfiles a bit better
- do not suggest that vendor configuration files should be in
  /etc, use /usr/lib/tmpfiles.d instead
- split the first example, because the text talked about "needing
  two directories", but then a smack attribute was also set, and
  on a different path, which looked like a typo. Replace that
  with the example from original patch [1] which added 't'.
- fix the example for /var/tmp/abrt. The 'x' line was redundant,
  because /var/tmp/abrt/* is already filtered because "d /var/tmp/abrt"
  overrides "d /var/tmp".

f6e1bd2c52 man: shorten the list of unit file paths a bit
Let's make this more digestable to read by making the list of documented unit
file paths a bit shorter.

Specifically, let's drop references to $XDG_CONFIG_HOME and $XDG_DATA_HOME, as
their default values are listed too already. Given that the fact that the XDG
basedir spec makes these paths configurable is probably not a strong point of
the spec, let's drop the reference to the env vars, and keep only the literal,
default paths for them in the list. Of course, we do support the full XDG
basedir spec in this regard, but it's one thing to implement it and another one
to recommend it by documenting it.

Replace "$HOME" by "~", because UNIX.

e01ff70a77 nspawn: always setup machine id
We check /etc/machine-id of the container and if it is already populated
we use value from there, possibly ignoring value of --uuid option from
the command line. When dealing with R/O image we setup transient machine
id.

Once we determined machine id of the container, we use this value for
registration with systemd-machined and we also export it via
container_uuid environment variable.

As registration with systemd-machined is done by the main nspawn process
we communicate container machine id established by setup_machine_id from
outer child to the main process by unix domain socket. Similarly to PID
of inner child.

David R. Hedges
63003524cb *.localdomain != localhost
".localdomain" is not a reserved suffix (or prefix). I'm not aware of any
product expecting *.localdomain to resolve to localhost, however I am aware of
at least one product that defaults to ".localdomain" as its DNS suffix provided
via DHCP (pfSense). This leads to unexpected results when attempting to access
a host that's offline (or a host that's online, when nsswitch.conf is
[mis-]configured to have myhostname ahead of DNS).

Operate on:
localhost (and localhost.)
*.localhost (and *.localhost.)
localhost.localdomain (and localhost.localdomain.)
*.localhost.localdomain (and *.localhost.localdomain.)

We should not cover:
*.localdomain (nor *.localdomain.)
localdomain (nor localdomain.)

19c0b0b9a5 core: set NoNewPrivileges for seccomp if we don't have CAP_SYS_ADMIN
The manpage of seccomp specify that using seccomp with
SECCOMP_SET_MODE_FILTER will return EACCES if the caller do not have
CAP_SYS_ADMIN set, or if the no_new_privileges bit is not set. Hence,
without NoNewPrivilege set, it is impossible to use a SystemCall*
directive with a User directive set in system mode.

Now, NoNewPrivileges is set if we are in user mode, or if we are in
system mode and we don't have CAP_SYS_ADMIN, and SystemCall*
directives are used.

9053aaad42 man: change recommended order of NSS modules in /etc/nsswitch.conf
So far we recommended placing "nss-mymachines" after "nss-resolve" in the order
of preference in /etc/nsswitch.conf. This change reverse this order.

Rationale: single-label names are resolved via LLMNR by resolved, which has to
time out if no peer by that name exists. By placing "nss-mymachines" first
(which always responds immediately) we avoid running into this timeout for most
containers. Both modules should return the same data if LLMNR is used by the
container anyway.

While we are at it, improve the man pages of the three NSS modules in other
ways a bit.

232c84b2d2 Remove systemd-bootchart
This commit rips out systemd-bootchart. It will be given a new home, outside
of the systemd repository. The code itself isn't actually specific to
systemd and can be used without systemd even, so let's put it somewhere
else.

788f37c725 man: link - add suggestion for debugging
udevadm test-builtin can be very useful for testing .link files, so add a reference.

Addresses issue #2406.

2ae7505f01 man: network - clarify BindCarrier documentation
Make it clear that we are talking of links (in the sense used in networkd) and not ports.

Addresses issue #964.

eb142d8ec1 man: network - improve IPv6Token documentation
Enabling router advertisement may even trigger SLAAC or DHCPv6 to be used to configure
IPv6 addresses on the link. It may not be obvious that only in the SLAAC case will the
Token have an effect. Clarify this in the man page.

Addresses issue #863.

7cececb2ea networkd: turn on LLDP reception by default, in "routers-only" mode
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.

34437b4f9c sd-lldp: rework sd-lldp API
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.

Also make the --help output and man page closer.
