This should be useful for cases where clean rebooting doesn't work, and

a986501b90 sysv-generator: there's really no need to invoke fstatat() multiple times on the same sysv script
It's sufficient to check once if something is a regular file, hence,

37cf8fee46 core: if two start jobs for the same swap device node are queued, only dispatch one of them at a time
If two start jobs for two seperate .swap device nodes are queued, which
then turns out to be referring to the same device node, refuse
dispatching more than one of them at the same time.

This should solve an issue when the same swap partition is found via GPT
auto-discovery and via /etc/fstab, where one uses a symlink path, and
the other the raw devce node. So far we might have ended up invoking
mkswap on the same node at the very same time with the two device node
names.

With this change only one mkswap should be executed at a time. THis
mkswap should have immediate effect on the other swap unit, due to the
state in /proc/swaps changing, and thus suppressing actual invocation of
the second mkswap.

11c6476a08 logind: chown+chmod /run/user/$UID if mount(tmpfs) fails with EPERM
In containers without CAP_SYS_ADMIN, it is not possible to mount tmpfs
(or any filesystem for that matter) on top of /run/user/$UID.
Previously, logind just failed in such a situation.

Now, logind will resort to chown+chmod of the directory instead. This
allows logind still to work in those environments, although without the
guarantees it provides (i.e. users not being able to DOS /run or other
users' /run/user/$UID space) when CAP_SYS_ADMIN is available.

4d858e7d9f logind: remove per-user runtime dir again if setup fails
If setup of per-user runtime dir fails, clean up afterwards by removing
the directory before returning from the function, so we don't leave the
directory behind.

If this is not done, the second time the user logs in logind would
assume that the directory is already set up, even though it isn't.

c62c4628d9 networkd-dhcp6: Assign DHCPv6 addresses and prefix lengths
Once IPv6 addresses have been acquired, assign these to the interface
with the prefix lengths taken from the ICMPv6 Router Advertisement
handling code. The preferred and valid IPv6 address lifetimes are
handed to the kernel which will clean up them if not renewed in time.

When a prefix announced via Router Advertisements expires, find all
addresses that match that prefix and update the address to have a
prefix length of 128 causing the prefix to be off-link.

99af546d0e test-icmp6-nd: Add test cases for prefixes
Add test cases that feeds an Router Advertisement to the ICMPv6 code
and verify that the correct prefix lengths are returned given an IPv6
address.

Enhance the prefix verification test by adding a shorter prefix and
check that the intended prefix lengths are now updated.

d77bde34cf sd-icmp6-nd: Parse ICMPv6 prefix information
Save each new onlink IPv6 prefix and attach an expiry timer to it.
If the prefixes overlap, take the shorter prefix and write a debug
message about the event. Once the prefix is resent in a Router
Advertisement, update the timer. Add a new event for the expiring
prefix.

Add two helper functions, one for returning a prefix length given a
Router Advertisement and the other for generic prefix matching given
an IPv6 prefix and address.

We should prefer the unifont.hex file from the system, instead of our

and we should follow upstream changes. But adding 2.6MB to our source
repo every time upstream releases is not nice.

4a84f3e614 TODO: remove laccess conversion
I looked over all access invocations, and I think are using access()
correctly. Accepting dangling symlinks makes sense only in special
circumstances.

So far we do not allow "flag" files like "/fastboot" to be dangling
symlinks. We could, but I don't see a reason to.

7e26029ff3 timesyncd: set RLIMIT_NPROC to 2
This way timesyncd cannot be used to fork().

Note that it generally is not safe to use RLIMIT_NPROC, since it breaks
running the same daemon in multiple containers if they do not use user
namespacing. However, timesyncd is excepted from running in a container
anyway, hence it is safe in this case.

6b321a7901 system-update-generator: accept a dangling symlink
The offline update mechanism is explicitly designed to work with a
separate /var. systemd-update-generator is supposed to run early,
before filesystems are mounted, so it cannot check if the
/system-update symlink actually points to anything.

The update is run *after* filesystems are mounted, so it should be
able to access the target of the symlink without trouble.

b381de4197 sd-bus: change serialization of kdbus messages to qualify in their entirety as gvariant objects
Previously, we only minimally altered the dbus1 framing for kdbus, and
while the header and its fields where compliant Gvariant objects, and so
was the body, the entire message together was not.

As result of discussions with Ryan Lortie this is now changed, so that
the messages in there entirely are fully compliant GVariants. This
follows the framing description described here:

https://wiki.gnome.org/Projects/GLib/GDBus/Version2

Note that this change changes the framing of *all* messages sent via
kdbus, this means you have to reboot your kdbus system, after compiling
and installing this new version.

ebf31a1f58 tmpfiles: use casts instead of warning suppression
