Infix v25.01.0

Note

This release contains breaking changes in the configuration file
syntax for DHCP clients. Specifically DHCP options with value,
i.e., the syntax for sending a hexadecimal value now require hex
prefix before a string of colon-separated pairs of hex values.

Changes

• Upgrade Linux kernel to 6.12.11 (LTS)
• Upgrade Buildroot to 2024.02.10 (LTS)
• Upgrade FRR from 9.1.2 to 9.1.3
• Add support for configuring SSH server, issue #441. As a result,
  both SSH and NETCONF now use the same host key in factory-config
• Add operational support for reading DNS resolver info, issue #510
• Add operational support for NTP client, issue #510
• Add support for more mDNS settings: allow/deny interfaces, acting
  as "reflector" and filtering of reflected services. Issue #678
• Add DHCPv4 server support, multiple subnets with static hosts and
  DHCP options on global, subnet, or host level, issue #703.

  • DHCP client options aligned with DHCP server, startup-config
    files with old syntax are automatically migrated
• Breaking change in DHCP client options with value. Hexadecimal
  values must now be formatted as { "hex": "c0:ff:ee" } (JSON)
• Add documentation on management via SSH, Web (RESTCONF, Web
  Console), and Console Port, issue #787
• Add documentation of DNS client use and configuration, issue #798
• Add support for changing boot order for the system with an RPC,
  including support for reading boot order from operational datastore

• Add support for VXLAN tunnels

Fixes

• Fix #777: Authorized SSH key not applied to startup-config
• Fix #829: Avahi (mDNS responder) not starting properly on switches
  with many ports (>10). This led to a review of sysctl:
  • New for IPv4:
    • Adjust IGMP max memberships: 20 -> 1000
    • Use neighbor information on nexthop selection
    • Use inbound interface address on ICMP errors
    • Ignore routes with link down
    • Disable rp_filter
    • ARP settings have been changed to better fit routers, i.e.,
      systems with multiple interfaces:
      • Always use best local address when sending ARP
      • Only reply to ARP if target IP is on the inbound interface
      • Generate ARP requests when device is brought up or HW address changes
  • New for IPv6:
    • Keep static global addresses on link down
    • Ignore routes with link down
• Fix #861: Fix error when running 251+ reconfigurations in test-mode
• Fix #869: Setup of bridges is now more robust
• Fix #899: DHCP client with client-id does not work
• Minor cleanup of Networking Guide
