7163e1ca11 Create initrd-root-device.target synchronization point (#3239)
Add a synchronization point so that custom initramfs units can run
after the root device becomes available, before it is fsck'd and
mounted.

This is useful for custom initramfs units that may modify the
root disk partition table, where the root device is not known in
advance (it's dynamically selected by the generators).

7272b25e16 networkd: reworkd LLDP emission to allow control of propagation level
This allows selecting the propagation level of emitted LLDP packets
(specifically: the destination MAC address of the packets). This is useful
because it allows generating LLDP packets that optionally cross certain types
of bridges.

See 802.11ab-2009, Table 7-1 for details.

c5a11ae268 logind: enforce a limit on inhibitors we hand out
For similar reasons as the recent addition of a limit on sessions.

Note that we don't enforce a limit on inhibitors per-user currently, but
there's an implicit one, since each inhibitor takes up one fd, and fds are
limited via RLIMIT_NOFILE, and the limit on the number of processes per user.

183e073842 logind: enforce a limit on current user sessions
We really should put limits on all resources we manage, hence add one to the
number of concurrent sessions, too. This was previously unbounded, hence set a
relatively high limit of 8K by default.

Note that most PAM setups will actually invoke pam_systemd prefixed with "-",
so that the return code of pam_systemd is ignored, and the login attempt
succeeds anyway. On systems like this the session will be created but is not
tracked by systemd.

c953b24c65 networkd: add support to set route table
networkd: add support to set route table
1. add support to configure the table id.
   if id is less than 256 we can fit this in the header of route as
   netlink property is a char. But in kernel this proepty is a
   unsigned 32. Hence if greater that 256 add this as RTA_TABLE
attribute.

2. we are not setting the address family now. Now set this property.

072993504e core: move enforcement of the start limit into per-unit-type code again
Let's move the enforcement of the per-unit start limit from unit.c into the
type-specific files again. For unit types that know a concept of "result" codes
this allows us to hook up the start limit condition to it with an explicit
result code. Also, this makes sure that the state checks in clal like
service_start() may be done before the start limit is checked, as the start
limit really should be checked last, right before everything has been verified
to be in order.

The generic start limit logic is left in unit.c, but the invocation of it is
moved into the per-type files, in the various xyz_start() functions, so that
they may place the check at the right location.

Note that this change drops the enforcement entirely from device, slice, target
and scope units, since these unit types generally may not fail activation, or
may only be activated a single time. This is also documented now.

Note that restores the "start-limit-hit" result code that existed before
6bf0f408e4 already in the service code. However,
it's not introduced for all units that have a result code concept.

Fixes #3166.

f0367da7d1 core: rename StartLimitInterval= to StartLimitIntervalSec=
We generally follow the rule that for time settings we suffix the setting name

exception was the rate limiting interval settings. Fix this, and keep the old
names for compatibility.

7629ec4642 core: move start ratelimiting check after condition checks
With #2564 unit start rate limiting was moved from after the condition checks
are to before they are made, in an attempt to fix #2467. This however resulted
in #2684. However, with a previous commit a concept of per socket unit trigger
rate limiting has been added, to fix #2467 more comprehensively, hence the
start limit can be moved after the condition checks again, thus fixing #2684.

Fixes: #2684

8b26cdbd2a core: introduce activation rate limiting for socket units
This adds two new settings TriggerLimitIntervalSec= and TriggerLimitBurst= that
define a rate limit for activation of socket units. When the limit is hit, the
socket is is put into a failure mode. This is an alternative fix for #2467,
since the original fix resulted in issue #2684.

In a later commit the StartLimitInterval=/StartLimitBurst= rate limiter will be
changed to be applied after any start conditions checks are made. This way,
there are two separate rate limiters enforced: one at triggering time, before
any jobs are queued with this patch, as well as the start limit that is moved
again to be run immediately before the unit is activated. Condition checks are
done in between the two, and thus no longer affect the start limit.

Let's move DUID configuration into the [DHCP] section, since it only makes

other per-protocol specific identifiers...

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.
