2023-10-03login: T5521: home directory owner changed during rebootChristian Breunig
During system startup the system-login.py script is invoked by vyos-router systemd service. As there is no complete configuration available at this point in time - and the sole purpose of this call is to reset/re-render the system NSS/PAM configs back to default - it accidently also deleted the local useraccounts. Once the VyOS configuration got mounted, users got recreated in alphabetical order and thus UIDs flipped and the /home suddenely belonged to a different account. This commit prevents any mangling with the local userdatabase during VyOS bootup phase.
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.

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.

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'
