I found several issues with zsh completion code:
1. typo in cache filename: "SYS_ALL_PROPRTIES", so cache just not loading from this file
2. cache stored in one file, despite user or system mode. So it can be loaded later in wrong mode
3. most serious problem: broken logic - it retrieves cache when _cache_invalid is true
How to reproduce: type "systemctl --user status <TAB>" and you will see user units. Then press
control+C and type "systemctl --system status <TAB>" in same session and you'll see user units again
Otherwise we fail an assertion down the path since t->timeout_event_source is NULL
and it's the "other" transaction that's supposed to have the event source.

By default all sent multicast packets are looped back to the
sending host. And since the code that adds the mDNS socket to
the mDNS multicast group is the same as for LLMNR I decided
that for now it'd be safer to filter looped back packets in the
application than to switch loopback off. Because I don't know
what would be the implications for LLMNR with loopback switched off.
I suspect that loopback can be disabled for LLMNR safely too and the
function manager_our_packet() is not really needed. But I'd
prefer to do it in another patchset.

Currently resolving mDNS requests doesn't work because in
dns_transaction_process_reply() no answer gets installed into
mDNS transactions.
When receiving a mDNS reply we should not check for query section
equivalence of the request and its corresponsing response. But still
we need to install answers to mDNS transactions to make it possible
to actually resolve mDNS requests.

This substantially reworks the seccomp code, to ensure better
compatibility with some architectures, including i386.
So far we relied on libseccomp's internal handling of the multiple
syscall ABIs supported on Linux. This is problematic however, as it does
not define clear semantics if an ABI is not able to support specific
seccomp rules we install.
This rework hence changes a couple of things:
- We no longer use seccomp_rule_add(), but only
seccomp_rule_add_exact(), and fail the installation of a filter if the
architecture doesn't support it.
- We no longer rely on adding multiple syscall architectures to a single filter,
but instead install a separate filter for each syscall architecture
supported. This way, we can install a strict filter for x86-64, while
permitting a less strict filter for i386.
- All high-level filter additions are now moved from execute.c to
seccomp-util.c, so that we can test them independently of the service
execution logic.
- Tests have been added for all types of our seccomp filters.
- SystemCallFilters= and SystemCallArchitectures= are now implemented in
independent filters and installation logic, as they semantically are
very much independent of each other.

When a new entry appears in /proc/self/mountinfo, mount_setup_unit()
allocated a new mount unit for it and starts initializing it.
mount_setup_unit() is also used to update a mount unit when a change happens in
/proc/self/mountinfo, for example a mountpoint can be remounted with additional
mount options.
This patch introduces 2 separate functions to deal with those 2 cases instead
of mount_setup_unit() dealing with both of them. The common code is small and
doing the split makes the code easier to read and less error prone if extended
later.
It also makes sure to initialize in both functions the mount parameters of the
mount unit before calling mount_is_extrinsic() since this function relies on
them.

RDNSS and DNSLL options received in RA are always used, possibly breaking the resolution of private domains hosted on a local DNS server. When setting UseDNS=no in a [IPv6AcceptRA] section of a .network file, both RDNSS and DNSLL options in received RA should be ignored.

The parameters were calculated on my X1 Yoga using touchpad-edge-detector; As as the device name indicates, the Touchpad is exactly the same as the X1 Carbon 4th gen.
A fixed value (6 and later 5) was added back in 4deb3b9391, and
not updated when load_len was added later on.
Also the other 5 with 1 + 1 + 1 + 1 + 1 to make it easier to see
that this is about the column separators.
After parsing the --verify-key argument, overwrite it with null bytes.
This minimizes (but does not completely eliminate) the time frame within
which another process on the system can extract the verification key
from the journalctl command line.
