2024-01-21dns: T5959: Streamline dns forwarding serviceIndrajit Raychaudhuri
Streamline configuration and operation of dns forwarding service in following ways: - Remove `dns_forwarding_reset.py` as its functionality is now covered by `dns.py` - Adjust function names in `dns.py` to disambiguate between DNS forwarding and dynamic DNS - Remove `dns_forwarding_restart.sh` as its functionality is inlined in `dns-forwarding.xml` - Templatize systemd override for `pdns-recursor.service` and move the generated override files in /run. This ensures that the override files are always generated afresh after boot - Simplify the systemd override file by removing the redundant overrides - Relocate configuration path for pdns-recursor to `/run/pdns-recursor` and utilize the `RuntimeDirectory` default that pdns-recursor expects - We do not need to use custom `--socket-dir` path anymore, the default path (viz., `/run/pdns-recursor` is fine)

2024-01-15T5901: Add DHCP base_path dir during first bootViacheslav Hletenko
We should create dhclient base_path dir `/run/dhclient` during the first boot. It fixes cloud-init boot issues ``` /etc/dhcp/dhclient-exit-hooks.d/03-vyos-dhclient-hook: line 33: /run/dhclient/dhclient_eth0.lease: No such file or directory ```
2024-01-14T4856: Fix IPsec DHCP-client exit hookViacheslav Hletenko
The script acually does not have the variable `secrets_lines` and secret lines itself does not have the marker `# dhcp:{interface}` in `to_find` Needs to rewrite this script in the future if it is required This commit fixes DHCP-client exit hook: ``` dhclient[6800]: NameError: name 'secrets_lines' is not defined root[6801]: /etc/dhcp/dhclient-exit-hooks.d/99-ipsec-dhclient-hook returned non-zero exit status 1 ```
2024-01-09https: T5902: remove virtual-host configurationChristian Breunig
We have not seen the adoption of the https virtual-host CLI option. What it did? * Create multiple webservers each listening on a different IP/port (but in the same VRF) * All webservers shared one common document root * All webservers shared the same SSL certificates * All webservers could have had individual allow-client configurations * API could be enabled for a particular virtual-host but was always enabled on the default host This configuration tried to provide a full webserver via the CLI but VyOS is a router and the Webserver is there for an API or to serve files for a local-ui. Changes Remove support for virtual-hosts as it's an incomplete and thus mostly useless "thing". Migrate all allow-client statements to one top-level allow statement.
2024-01-06pki: T5886: add support for ACME protocol (LetsEncrypt)Christian Breunig
The "idea" of this PR is to add new CLI nodes under the pki subsystem to activate ACME for any given certificate. vyos@vyos# set pki certificate NAME acme Possible completions: + domain-name Domain Name email Email address to associate with certificate listen-address Local IPv4 addresses to listen on rsa-key-size Size of the RSA key (default: 2048) url Remote URL (default: https://acme-v02.api.letsencrypt.org/directory) Users choose if the CLI based custom certificates are used set pki certificate EXAMPLE acme certificate <base64> or if it should be generated via ACME. The ACME server URL defaults to LetsEncrypt but can be changed to their staging API for testing to not get blacklisted. set pki certificate EXAMPLE acme url https://acme-staging-v02.api.letsencrypt.org/directory Certificate retrieval has a certbot --dry-run stage in verify() to see if it can be generated. After successful generation, the certificate is stored in under /config/auth/letsencrypt. Once a certificate is referenced in the CLI (e.g. set interfaces ethernet eth0 eapol certificate EXAMPLE) we call vyos.config.get_config_dict() which will (if with_pki=True is set) blend in the base64 encoded certificate into the JSON data structure normally used when using a certificate set by the CLI. Using this "design" does not need any change to any other code referencing the PKI system, as the base64 encoded certificate is already there. certbot renewal will call the PKI python script to trigger dependency updates.

2023-12-31T5474: establish common file name pattern for XML conf mode commandsChristian Breunig
We will use _ as CLI level divider. The XML definition filename and also the Python helper should match the CLI node. Example: set interfaces ethernet -> interfaces_ethernet.xml.in set interfaces bond -> interfaces_bond.xml.in set service dhcp-server -> service_dhcp-server-xml.in
2023-12-20srv6: T591: enable SR enabled packet processing on defined interfacesChristian Breunig
The Linux Kernel needs to be told if IPv6 SR enabled packets whether should be processed or not. This is done using /proc/sys/net/conf/<iface>/seg6_* variables: seg6_enabled - BOOL Accept or drop SR-enabled IPv6 packets on this interface. Relevant packets are those with SRH present and DA = local. 0 - disabled (default) not 0 - enabled Or the VyOS CLI command: * set protocols segment-routing interface eth0 srv6
2023-12-20vrf: T591: define sysctl setting for net.vrf.strict_modeChristian Breunig
Enable/Disable VRF strict mode, when net.vrf.strict_mode=0 (default) it is possible to associate multiple VRF devices to the same table. Conversely, when net.vrf.strict_mode=1 a table can be associated to a single VRF device. A VRF table can be used by the VyOS CLI only once (ensured by verify()), this simply adds an additional Kernel safety net, but a requirement for IPv6 segment routing headers.

2023-12-02vti: T5769: restore interface settings on down -> up eventChristian Breunig
On VTI interface link down the link-local IPv6 address is removed. As soon as the IPSec tunnel is online again, vti-up-down helper is called which only places the interface in up state using iproute2 command sudo ip link set vti0 up This does not restore the IPv6 LL address. Instead use vyos.ifconfig to properly re-initialize the VTI interface using the generic update() method.
2023-11-20http: T5762: api: make API socket backend communication the one and only defaultChristian Breunig
Why: Smoketests fail as they can not establish IPv6 connection to uvicorn backend server. https://github.com/vyos/vyos-1x/pull/2481 added a bunch of new smoketests. While debugging those failing, it was uncovered, that uvicorn only listens on IPv4 connections vyos@vyos# netstat -tulnp | grep 8080 (Not all processes could be identified, non-owned process info will not be shown, you would have to be root to see it all.) tcp 0 0 127.0.0.1:8080 0.0.0.0:* LISTEN - As the CLI already has an option to move the API communication from an IP to a UNIX domain socket, the best idea is to make this the default way of communication, as we never directly talk to the API server but rather use the NGINX reverse proxy.

User hooks are executed using run_hookdir (defined in the /sbin/dhclient-script script) instead of run-parts. That allows user hooks to modify variables set by the dhcp client (e.g., the new_routers variable to avoid the installation of the default routes).

2023-11-04T5706: Add custom systemd udev rules to exclude dynamic interfacesViacheslav Hletenko
Add custom systemd udev rules to exclude some regular and dynamic interfaces from "systemd-sysctl" calls. It fixes high CPU utilization (100%) as we have a lot of calls per interface for dynamic interfaces like ppp|ipoe|sstp etc. /lib/systemd/systemd-udevd should not be called for those interfaces

2023-08-16netplug: T5476: rewrite dhclient helper from Perl -> PythonChristian Breunig
There are two hooks called for bridge, ethernet and bond interfaces if the link-state changes up -> down or down -> up. The helpers are: * /etc/netplug/linkdown.d/dhclient * /etc/netplug/linkup.d/dhclient As those helpers use Linux actions to start/restart the dhclient process in Perl it's time to rewrite it. First goal is to get rid of all Perl code and the second is that we now have a Proper Python library. Instead of checking if the process is running the then restarting it without even systemd noticing (yeah we might get two processes beeing alive) we should: * Add a Python helper that can be used for both up and down (see man 8 netplugd FILES section) * Query the VyOS CLI config if the interface in question has DHCP(v6) configured and is not disabled * Add IPv6 DHCPv6 support MAN page: https://linux.die.net/man/8/netplugd

Debian's `debian/2%2.10-12` update of the hostap packaging added a ConditionFileNotEmpty directive for `/etc/hostapd/<...>` paths, which doesn't match the `/run/hostapd/<...>` paths that VyOS uses.
