2023-09-15T5586: Disable by default SNMP for Keeplived VRRP serviceViacheslav Hletenko
AgentX does not work stable. From time to time we see the system service crashing/degrading if something is wrong with SNMP from util net-snmp. We should disable it by default and enable it only if configured. set high-availability vrrp snmp

ddclient: T5585: Fix file access mode for dynamic dns configuration
2023-09-15system: T5505: T5575: support calling system-ip(v6).py from init processChristian Breunig
After commit 976f82785 ("T5575: ARP/NDP table-size isnt set properly") the system bootup process got interrupted as both system-ip.py and system-ipv6.py tried to talk to FRR which was yet not started. This has been fixed by using a conditional path to only execute when FRR service has been enabled. This is safe to do as the initial commit call will has FRR service running and the path will be executed.

ddclient.conf file is expected to have permission 600. We need to set the permission explicitly while creating the file.

2023-09-13TACACS: T5577: Added `mandatory` and `optional` modes for TACACS+zsdc
In CLI we can choose authentication logic: - `mandatory` - if TACACS+ answered with `REJECT`, authentication must be stopped and access denied immediately. - `optional` (default) - if TACACS+ answers with `REJECT`, authentication continues using the next module. In `mandatory` mode authentication will be stopped only if TACACS+ clearly answered that access should be denied (no user in TACACS+ database, wrong password, etc.). If TACACS+ is not available or other errors happen, it will be skipped and authentication will continue with the next module, like in `optional` mode.

In CLI we can choose authentication logic: - `mandatory` - if RADIUS answered with `Access-Reject`, authentication must be stopped and access denied immediately. - `optional` (default) - if RADIUS answers with `Access-Reject`, authentication continues using the next module.

If RADIUS is not available or other errors happen, it will be skipped and authentication will continue with the next module, like in `optional` mode.

2023-09-11frr: T5239: fix process startup orderChristian Breunig
- Reuse existing utility functions to check if a boot is ongoing (boot_configuration_complete()) - Run system_frr.py script to configure FRR daemon before initial launch - Add safety net to always have FRR running on the system This does yet not solve the error in T5239 but it's a small step towards the solution.

2023-09-09T4502: firewall: Add software flow offload using flowtableYuxiang Zhu
The following commands will enable nftables flowtable offload on interfaces eth0 eth1: ``` set firewall global-options flow-offload software interface <name> set firewall global-options flow-offload hardware interface <name> ``` Generated nftables rules: ``` table inet vyos_offload { flowtable VYOS_FLOWTABLE_software { hook ingress priority filter - 1; devices = { eth0, eth1, eth2, eth3 }; counter } chain VYOS_OFFLOAD_software { type filter hook forward priority filter - 1; policy accept; ct state { established, related } meta l4proto { tcp, udp } flow add @VYOS_FLOWTABLE_software } } ``` Use this option to count packets and bytes for each offloaded flow: ``` set system conntrack flow-accounting ``` To verify a connection is offloaded, run ``` cat /proc/net/nf_conntrack|grep OFFLOAD ``` This PR follows firewalld's implementation: https://github.com/firewalld/firewalld/blob/e748b97787d685d0ca93f58e8d4292e87d3f0da6/src/firewall/core/nftables.py#L590 A good introduction to nftables flowtable: https://thermalcircle.de/doku.php?id=blog:linux:flowtables_1_a_netfilter_nftables_fastpath

2023-09-09vxlan: T3700: support VLAN tunnel mapping of VLAN aware bridgesChristian Breunig
FRR supports a new way of configuring VLAN-to-VNI mappings for EVPN-VXLAN, when working with the Linux kernel. In this new way, the mapping of a VLAN to a VNI is configured against a container VXLAN interface which is referred to as a 'Single VXLAN device (SVD)'. Multiple VLAN to VNI mappings can be configured against the same SVD. This allows for a significant scaling of the number of VNIs since a separate VXLAN interface is no longer required for each VNI. Sample configuration of SVD with VLAN to VNI mappings is shown below. set interfaces bridge br0 member interface vxlan0 set interfaces vxlan vxlan0 external set interfaces vxlan vxlan0 source-interface 'dum0' set interfaces vxlan vxlan0 vlan-to-vni 10 vni '10010' set interfaces vxlan vxlan0 vlan-to-vni 11 vni '10011' set interfaces vxlan vxlan0 vlan-to-vni 30 vni '10030' set interfaces vxlan vxlan0 vlan-to-vni 31 vni '10031'

2023-09-08T5518: Add basic MLD supportYuxiang Zhu
Currently VyOS has `protocol igmp` option to enable IGMP querier and reports through FRR's pimd. I would like to add support for IPv6 as well since FRR's IPv6 multicast functionality has significantly improved. Enabling both MLD and IGMP on a VyOS router will allow us to turn on multicast snooping on layer-3 switches in dual-stack networks. Example commands: ``` // Enable on interface eth0 set protocols pim6 interface eth0 // Explicitly join multicast group ff18::1234 on interface eth1 set protocols pim6 interface eth1 mld join ff18::1234 // Explicitly join source-specific multicast group ff38::5678 with source address 2001:db8::1 on interface eth1 set protocols pim6 interface eth1 mld join ff38::5678 source 2001:db8::1 ```

The following command expects to join source-specific multicast group 239.1.2.3 on interface eth0, where the source address is 192.0.2.1. set protocols igmp interface eth0 join 239.1.2.3 source 192.0.2.1 This command should generate FRR config: interface eth0 ip igmp ip igmp join 239.1.2.3 192.0.2.1 exit However, there is a bug in the Jinja template where `if ifaces[iface].gr_join[group]` is mostly evaluated as `false` because `iface` is a loop variable from another loop.
