Fixes: #14483
(cherry picked from commit d80e72ec602c2af2983842ad87e4443fce89d423)
UML runs as a user-process so it can quite easily be ran inside of
another hypervisor, for instance inside a KVM instance. UML passes
through the CPUID from the host machine so in this case detect_vm
incorrectly identifies as running under KVM. So check we are running
a UML kernel first, before we check any other hypervisors.

We need to check for parent domains too. We did this correctly for the
system-wide NTA list, but not for the per-link one. Let's fix that.

Quoting #17559:

Fixes#17559.

This test assumes capability_list_length() is an invalid cap number,
but that isn't true if the running kernel supports more caps than we were
compiled with, which results in the test failing.
Instead use cap_last_cap() + 1.
If cap_last_cap() is 63, there are no more 'invalid' cap numbers to test with,
so the invalid cap number test part is skipped.

Commit 42cc2855ba2fe4c6f5d incorrectly removed the condition on sysfs in both
sys-fs-fuse-connections.mount and sys-kernel-config.mount. However there are
still needed in case modprobe of one of these modules is intentionally skipped
(due to lack of privs for example).
This patch restores the 2 conditions which should be safe for the common case,
since all conditions are only checked after all deps ordered before are
complete.
Follow-up for 42cc2855ba2fe4c6f5dc863507a1c843611350a0.

These three syscalls are internally used by libc's memory allocation
logic, i.e. ultimately back malloc(). Allocating a bit of memory is so
basic, it should just be in the default set.
This fixes a couple of issues with asan/msan and the seccomp tests: when
asan/msan is used some additional, large memory allocations take place
in the background, and unless mmap/mmap2/brk are allowlisted these will
fail, aborting the test prematurely.

udev requests to start the fs mount units when their respective module is
loaded. For that it monitors uevents of type "ADD" for the relevant fs modules.
However the uevent is sent by the kernel too early, ie before the init() of the
module is called hence before directories in /sys/fs/ are created.
This patch workarounds adds "Requires/After=modprobe@<fs-module>.service" to
the mount unit, which means that modprobe(8) will be called once the fs module
is announced to be loaded. This sounds pointless, but given that modprobe only
returns after the initialization of the module is complete, it should
workaround the issue.
As a side effect, the module will be automatically loaded if the mount unit is
started manually.
Fixes#17586.

This reverts commit 9cbf1e58f9629af5c6b56777ee73dc6320306d6d.
The presence of /sys/module/%I directory can't be used to assert that the load
of a given module is complete and therefore the call to modprobe(8) can be
skipped. Indeed this directory is created before the init() function of the
module is called.
Users of modprobe@.service needs to be sure that once this service returns the
module is fully operational.

The configuration of networkd has a DHCPv6Client setting in its
[IPv6AcceptRA] section, which, according to the man page, can be
a boolean, or the special value "always". The man page states
that "true" is the default.
The default value is implemented in src/network/networkd-network.c
by setting field ipv6_accept_ra_start_dhcp6_client of network to
true. However, this field is not a boolean, but an enum type
IPv6AcceptRAStartDHCP6Client (src/network/networkd-ndisc.h).
Setting ipv6_accept_ra_start_dhcp6_client to true effectively
corresponds to the enum value IPV6_ACCEPT_RA_START_DHCP6_CLIENT_ALWAYS,
resulting in the DHCPv6Client setting having the default value
"always".
This patch changes the initialisation to the correct enum value
IPV6_ACCEPT_RA_START_DHCP6_CLIENT_YES.
