The default (40KB) isn't enough for all patches.

Fixes: 4d8dfb6a ("mailman: Third batch of mailman3 migrated lists")

Enable kernel lockdown in confidentiality mode to restrict how the root user can interact with the kernel.
See https://wiki.archlinux.org/title/Security#Kernel_lockdown_mode and https://man.archlinux.org/man/kernel_lockdown.7

This could prevent a scenario where a malicious kernel module or access to some interface that kernel lockdown prevents, would allow or assist in escaping the KVM.
It is not very likely as there needs to be an exploitable vulnerability in the hypervisor.
To make it more secure, the host too would need to enable kernel lockdown.

In the end this may only give some sense of security, but, as we all know, that's all that matters anyway.

It is cumbersome to manage the list configurations from the web ui and
easy for them to diverge, so let's instead manage them with Ansible.

Fix #254

The default of 0.5 has proven insufficient on at least 3 boxes so far.

Otherwise it can't open our letsencrypt certs. It will setuid to
`turnserver` itself.

We get a lot of unauthorized STUN requests in the logs.

Fixes: 26f289b7 ("Capitalize the first letter of all task names")

This avoid having extra-long lines and works fine for task-based rules.

This might be a bug in ansible-lint 6.5.0, but it appears to ignore all
our 'skip_ansible_lint' tags. Fix this by replacing them with noqa tags.

ansible-lint 6.5.0 complains about:

  name: All names should start with an
        uppercase letter. (name[casing])

Useful if we wanted to create a Geo-based archive consisting of machines
in the archive_mirrors group (though this will likely not happen because
it'd break archlinux-repro due to the ~4 hour sync delay).

When the GeoIP databases get refreshed (weekly), we want PowerDNS to
reload them. Do this by running pdns_control reload in ExecStartPost.

"poetry run" is very slow[1] and adds +1 second to the startup time.
This is made even worse by the fact that aurweb-git-serve is called
twice by sshd[2].

Microcode updates are not applicable to cloud servers.

http_requests_total  contains requests from debuginfo.al.org host
as well as from aur.al.org so filter them on job 'aurweb'

Using plain "borg" resolves to /usr/local/bin/borg which is the wrapper
for our main backup host. This causes the offsite backup to be executed
with BORG_REPO set to the main backup destination.

While the above doesn't cause any issues with the backup script/service,
because borg invocations specify the backup destination as an argument,
it's not ideal and/or correct. Adjust borg_cmd to include the full path
of /usr/bin/borg, thus removing any ambiguity.

rsync.net has upgraded to borg 1.2 and we can now run borg compact on
both rsync.net and the Hetzner storage box.

Fixes: 17927c9a ("borg_client: run compact after pruning on borg 1.2")

Update /etc/rebuilderd-sync.conf to use the Geo host mirror instead of
europe.mirror.pkgbuild.com (for added reliability in case the latter's
availability is impacted).

The /api/v0/build/report endpoint has received POSTs up to 161M so far
this year (2022). In 2021 there had been POSTs of sizes up to 404M and
up to 814M for 2020. Multiple hundreds of MB seem a bit excessive, but
we should be able to do up to 200M.

Remove a few stray TABs and correct double-indented lines.

Upstream archlinux-repro was already using europe.mirror.pkgbuild.com as
its bootstrap and regular mirror. Furthermore, since [1] it has switched
to the Geo mirror. Remove both vars from /etc/archlinux-repro/repro.conf
and use the default mirror values (which are more than suitable).
