Allow out of band communication between qemu VMs and the host.
Useful to retrieve IPs of VMs from the host (for instance when libvirt can't analyze
DHCP requests because VMs are configured with static addresses or when
there is connectivity default).
This patch is heavily inspired by bd0d8ed807 which added
a setcap wrapper for `mtr` in order to allow running `mtr` without
`sudo`. The need for the capability `cap_net_raw` that can be registered using
`setcap` has been documented in the Arch Wiki: https://wiki.archlinux.org/index.php/Capabilities#iftop
A simple testcase has been added which starts two machines, one with a
setcap wrapper for `iftop`, one without. Both testcases monitor the
bandwidth usage of the machine using the options `-t -s 1` once, the
machine with setcap wrapper is expected to succeed, the `iftop` on the
machine without setcap wrapper is expected to return a non-zero exit
code.
- prometheus exporters are now configured with
`services.prometheus.exporters.<name>`
- the exporters are now defined by attribute sets
from which the options for each exporter are generated
- most of the exporter definitions are used unchanged,
except for some changes that should't have any impact
on the functionality.
By default, OnlyKey device (https://crp.to/p/) won't work on Linux (and,
therefore, NixOS). This is unintuitive and requires one to search for a
solution in the documentation.
This change allows one to enable OnlyKey device support directly from
their NixOS configuration.
All 5 daemon types can be enabled and configured through the module and the module both creates the ceph.conf required but also creates and enables specific services for each daemon, based on the systemd service files that upstream provides.
The strongswan-swanctl systemd service starts charon-systemd. This implements a IKE daemon
very similar to charon, but it's specifically designed for use with systemd. It uses the
systemd libraries for a native integration.
Instead of using starter and an ipsec.conf based configuration, the daemon is directly
managed by systemd and configured with the swanctl configuration backend.
See: https://wiki.strongswan.org/projects/strongswan/wiki/Charon-systemd
Note that the strongswan.conf and swantctl.conf configuration files are automatically
generated based on NixOS options under services.strongswan-swanctl.strongswan and
services.strongswan-swanctl.swanctl respectively.
