The `openssh` and `openssh_hpn` packages are now built without
the Kerberos support by default in an effort to reduce the attack surface.
The Kerberos support is likely used only by a fraction of the total users
(I'm guessing mainly users integrating SSH in an Active Directory env) so
dropping it should not impact too many users. It should also be noted that
the Kerberos/GSSAPI auth is disabled by default in the configuration.
`opensshWithKerberos` and `openssh_hpnWithKerberos` are added in order
to provide an easy migration path for users needing this support.
The `openssh_gssapi` package is kept untouched.
# Motivation
So far it was not possible to configure sshd to allow password authentication only for a specific user. This is because in the generated config a `Match User xxx` section would be required before the global `PasswordAuthentication` is defined, as otherwise the global option always takes precedence.
The same problem occurs with multiple other options under `settings`.
# Done
This PR fixes that issue for all settings by simply allowing them to be overridden with `null`, which leads to a removal of that setting from the config.
The user can then correctly configure user specific settings using extraConfig, like this:
```
Match User user1
PasswordAuthentication yes
Match all
PasswordAuthentication no
```
This patch is about removing `wireguardPeerConfig`,
`dhcpServerStaticLeaseConfig` - a.k.a. the
AbstractSingletonProxyFactoryBean of nixpkgs - and friends.
As a former colleague said
> worst abstraction ever
I second that. I've written enough networkd config for NixOS systems so
far to have a strong dislike. In fact, these don't even make sense:
`netdevs.wireguardPeers._.wireguardPeerConfig` will be rendered into
the key `[WireGuardPeer]` and every key from `wireguardPeerConfig` is in
there. Since it's INI, there's no place where sections on the same level
as wireguardPeerConfig fit into. Hence, get rid of it all.
For the transition, using the old way is still allowed, but gives a
warning. I think we could drop this after one release.
The tests of rosenpass and systemd-networkd-dhcpserver-static-leases
were broken on the rev before, hence they were updated, but are still
not building.
Add missing http:// scheme. Without it pixiecore logs this and never
contacts the API server:
[DHCP] Couldn't get bootspec for [REDACTED_MAC_ADDR]: Get "localhost:8080/v1/boot/[REDACTED_MAC_ADDR]": unsupported protocol scheme "localhost"
Motivation: Allow the sshd package to be built differently to the ssh
package (programs.ssh.package). For example, build sshd(1) without
openssl, but built ssh(1) with OpenSSL support.
Set the default to be programs.ssh.package, to preserve compatibility.
