2023-09-30vrf: netns: T3829: T31: priority needs to be after netnsChristian Breunig
A network namespace can have VRFs assigned, thus we need to get the priorities right. This lowers both priorities in general as a VRF or NETNS needs to be available very early as services can run on top of them.

2023-09-30ddclient: T5574: Support per-service cache management for servicesIndrajit Raychaudhuri
Add support for per-service cache management for ddclient providers via `wait-time` and `expiry-time` options. This allows for finer-grained control over how often a service is updated and how long the hostname will be cached before being marked expired in ddclient's cache. More specifically, `wait-time` controls how often ddclient will attempt to check for a change in the hostname's IP address, and `expiry-time` controls how often ddclient to a forced update of the hostname's IP address. These options intentionally don't have any default values because they are provider-specific. They get treated similar to the other provider- specific options in that they are only used if defined.

This commit adds a new configuration option to the mDNS repeater service to allow controlling which IP version to use for mDNS repeater. Additionally, publishing AAAA record over IPv4 and A record over IPv6 is disabled as suggested.

Since TTL is not supported by all protocols, and thus cannot have a configuration default, the existing XML snippet `include/dns/time-to-live.xml.i` does not have common `<defaultValue>300</defaultValue>` anymore and is instead added explicitly whenever necessary.

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.

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'

T4072: add firewall bridge filtering.
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 ```
