The sysfs file /sys/kernel/mm/ksm/run seems to be available as soon as
the kernel has started, so no point in waiting for udev to "settle". If
for some reason it doesn't, we let the unit fail explicitly.
Launching a container with a private network requires creating a
dedicated networking interface for it; name of that interface is derived
from the container name itself - e.g. a container named `foo` gets
attached to an interface named `ve-foo`.
An interface name can span up to IFNAMSIZ characters, which means that a
container name must contain at most IFNAMSIZ - 3 - 1 = 11 characters;
it's a limit that we validate using a build-time assertion.
This limit has been upgraded with Linux 5.8, as it allows for an
interface to contain a so-called altname, which can be much longer,
while remaining treated as a first-class citizen.
Since altnames have been supported natively by systemd for a while now,
due diligence on our side ends with dropping the name-assertion on newer
kernels.
This commit closes #38509.

The NixOS manual documents that you can invoke every tests using
nix-build path/to/nixos/tests/test.nix
which was not the case for openldap since it is not autocallable, but
requires pkgs and system as arguments. Usually, make-test-pythons.nix
takes care of this if it is imported at the top-level, but since
openldap.nix contains multiple tests, this was not the case.
This is however easily fixed by:
* Adding default values for the pkgs and system arguments based on the
definition in make-test-python.nix
* Passing pkgs and system explicitly to make-test-python.nix to ensure
the pkgs and system values passed from all-tests.nix are used.
VM tests are expensive (and prone to random failures) so they should
only be used for things that can only be tested in a VM, not for
things that could be tested in a regular checkPhase or derivation.
Exclude static 192.168.*.2 addresses from the dynamic address range to
prevent different interfaces from getting the same address.
Seems like configuring a fixed IPv4 address does not automatically
exclude it from the dynamic address range.
Should fix occasional failures of
nixos.tests.networking.scripted.macvlan and possibly other networking
tests relying on DHCP.
