The option `LinkLocalTCPPort` does not exist anymore in recent versions
of Yggdrasil. The port for incoming link-local connections is now
configured as part of the `MulticastInterfaces` option. Our
documentation should reflect that.
As far as I can tell the configFile option cannot have worked as
intended. The Yggdrasil systemd service uses a dynamic user. As it was,
there was no way to set the correct permissions on a config file
beforehand which would allow the dynamic user to read the config file
without making it readable for all users. But since the config file can
contain a private key it *must not* be world-readable.
The file must only be readable by root. The file has to be copied and
the permissions have to be fixed during service startup. This can either
be done in a ExecStartPre directive with the '+' prefix (which executes
that command with elevated privileges), or it can be done more
declarative with the LoadCredential directive. I have chosen the latter
approach because it delegates more work to systemd itself. It should be
noted that this has the minor tradeoff that the config file must not be
larger than 1 MB. This is a limit which systemd imposes on credential
files. But I think 1 MB ought to be enough for anybody ;).
this converts meta.doc into an md pointer, not an xml pointer. since we
no longer need xml for manual chapters we can also remove support for
manual chapters from md-to-db.sh
since pandoc converts smart quotes to docbook quote elements and our
nixos-render-docs does not we lose this distinction in the rendered
output. that's probably not that bad, our stylesheet didn't make use of
this anyway (and pre-23.05 versions of the chapters didn't use quote
elements either).
also updates the nixpkgs manual to clarify that option docs support all
extensions (although it doesn't support headings at all, so heading
anchors don't work by extension).
conversions were done using https://github.com/pennae/nix-doc-munge
using (probably) rev f34e145 running
nix-doc-munge nixos/**/*.nix
nix-doc-munge --import nixos/**/*.nix
the tool ensures that only changes that could affect the generated
manual *but don't* are committed, other changes require manual review
and are discarded.
markdown can't represent the difference without another extension and
both the html manual and the manpage render them the same, so keeping the
distinction is not very useful on its own. with the distinction removed
we can automatically convert many options that use <code> tags to markdown.
the manpage remains unchanged, html manual does not render
differently (but class names on code tags do change from "code" to "literal").
the conversion procedure is simple:
- find all things that look like options, ie calls to either `mkOption`
or `lib.mkOption` that take an attrset. remember the attrset as the
option
- for all options, find a `description` attribute who's value is not a
call to `mdDoc` or `lib.mdDoc`
- textually convert the entire value of the attribute to MD with a few
simple regexes (the set from mdize-module.sh)
- if the change produced a change in the manual output, discard
- if the change kept the manual unchanged, add some text to the
description to make sure we've actually found an option. if the
manual changes this time, keep the converted description
this procedure converts 80% of nixos options to markdown. around 2000
options remain to be inspected, but most of those fail the "does not
change the manual output check": currently the MD conversion process
does not faithfully convert docbook tags like <code> and <package>, so
any option using such tags will not be converted at all.
The group configuration parameter allow to share access to yggdrasil
control socket with the users in the system. In the version we propose,
it is null by default so that only root can access the control socket,
but let user create their own group if they need.
Remove User= durective in systemd unit. Should a user with the specified
name already exist in the system, it would be used silently instead of a
dynamic user which could be a security concern.
Since version 0.4 Yggdrasil works again using systemd's DynamicUser option.
This patch reenables it to improve security.
We tested this with both persistent and non-persistent keys. Everything
seems to work fine.
Favor the configuration in "configFile" over "config" to allow
"configFile" to override "config" without a system rebuild.
Add a "persistentKeys" option to generate keys and addresses that
persist across service restarts. This is useful for self-configuring
boot media.
