News: this release marks the first major upgrade of the underlying Buildroot to the latest LTS release, v2024.02. This caused a few small regressions in the release cycle, all known issues have been addressed.

Also worth highlighting, as of this release the Infix Classic variant has been dropped. It was the legacy Infix with manual configuration of the system using a persistent /etc. May be resurrected later as a separate project. Going forward Infix' focus is entirely on NETCONF.

Finally, the YANG Status section has been dropped for this release, the idea is to generate supported features from the models and include in future releases.

Changes

  • Bump the base Buildroot version to v2024.02 LTS
  • Bump the base Linux kernel version to 6.6 LTS
  • Drop Classic variant to reduce overhead, simplify build & release processes, and focus on NETCONF for Arm64 and Amd64 platforms
  • Add hostname restrictions to ietf-system, and infix-dhcp-client models. Max 64 characters on Linux systems
  • Add mDNS CNAME (alias) advertisement, e.g., infix.local in addition to the default infix-c0-ff-ee.local. Note: this is build-specific and does not change if system hostname is changed
  • Add mDNS browser web application, https://network.local that shows all mDNS devices on the LAN. The network.local mDNS name is also a CNAME, so with multiple Infix devices, only one will act as the mDNS browser
  • Add temporary landing page to web server for https://infix.local
  • Add web console using ttyd, https://infix.local:7681
  • Add support for disabling web services using CLI
  • The bridge model now has built-in validation of port memberships, i.e., a port must be a bridge member to be used in VLAN filtering
  • The bridge model only permits the bridge itself to be a tagged member of VLANs -- meaning, the only way to set an IP address on such bridges is to use a VLAN interface on top
  • A VLAN filtering bridge now validates that no IP address has been set. Use a VLAN interface on top for that (see above)
  • Restructure documentation, let first page in doc/ be table of contents
  • Scripting Infix, new document on how to script Infix from remote, e.g., for production or from a container
  • Introduction, update documentation now that the admin user's default login shell is /bin/bash
  • System documentation, first outline of how to change hostname, add users, add system administrator users, changing login banner, change the system default editor, and more
  • Network documentation, add section on VETH pairs
  • Container documentation:
    • CLI prompts have been updated to match the examples used in other parts of the User Guide
    • Default route example for static container interfaces
    • How to upgrade a container image
  • As a follow-up to port speed/duplex/autoneg support added in v24.02, this release ensures flow-control is always disabled on all Ethernet ports, as described in the IEEE Ethernet interfaces YANG model
  • Add support for core dumps, saving them in /var/crash, max one dump per process, for use with future support tarballs
  • Add support for multicast snooping, both IPv4 (IGMP) and IPv6 (MLD) in bridge setups, including offloading to switchdev
  • Add support for acting as passive (proxy) or active IGMP querier
  • Add support for static multicast filters, MAC, IPv4 and IPv6 groups are supported -- multicast snooping must be enabled
  • Include Buildroot legal-info in releases, i.e., licenses, sources with patches, as well as csv files for packages and toolchain
  • Drop shell command from CLI to allow confining users
  • The CLI copy command now allows absolute paths
  • Local resolver, dnsmasq, had port 53 visible from external nmap scans, even though it dropped non-local requests, it now only binds to the loopback interface reduce number of externally visible ports
  • Kernel log messages, of severity error or higher, now log directly to the console. This may cause some annoyance but has been enabled to ease debugging, in particular issues where the system crashes before the syslog daemon has flushed logs to disk. (Logs are still saved to log files as well.)
  • Issue #325: Add support for multiple administrator users by opening up basic NETCONF ACM support. See documentation for details
    • Any user can be added to the admin NACM group
    • Any user not in the admin group is not allowed to have a login shell other than the CLI (or disabled). POSIX shell, e.g., Bash is reserved for system administrators
  • Issue #327: Remove IPv6LL from bridge port interfaces
  • Issue #358: translate YANG model's LOWER-LAYER-DOWN -> LINK-DOWN in CLI show interfaces command
  • Issue #360: document factory-config, startup-config, and the various failure modes in the system
  • Issue #361: document how a privileged container can break out of its confinement and run host commands, e.g., call sysrepocfg
  • Issue #365: add limited support for container capabilities, e.g., to enable CAP_NET_RAW to allow containers to use ping. This allows users to avoid enabling privileged mode
  • Issue #367: setting date/time over NETCONF now saves system time also to the RTC, which otherwise is only saved on reboot or power-down
  • Issue #369: Remove limitation that the routing instance must be named 'default'

Fixes

  • confd: Fix memory leak when operating on candidate configuration
  • probe: Fix crash on systems without USB
  • Reduced syslog errors for accesses no non-existing xpaths
  • Fix bogus warning about not properly updating /etc/motd in new motd-banner setting, introduced in v24.02.0
  • infix-routing model: the enable configuration setting for OSPF, in default-route-advertise has been obsoleted and replaced by enabled
  • Fix #328: when setting up a VLAN filtering bridge, the PVID for bridge ports defaulted to 1, making it impossible to set up "tagged-only" ports which drop ingressing untagged traffic
  • Fix #329: VLAN inference for interfaces named eth0.1, i.e., VID 1 on lower-layer-if eth0. Only affects automatic inference in the CLI, entering the values manually (CLI/NETCONF) not affected by this bug
  • Fix #331: inconsistent naming of 'enabled' in infix-routing.yang
  • Fix #349: minor changes to bridge-port settings, like setting pvid when you forget it, did not take without a reboot
  • Fix #353: impossible to remove bridge port with no bridge-port
  • Fix #358: MAC address no longer shown for bridge interfaces in CLI show interfaces command
  • Fix #365: not possible to run ping from container
  • Fix #366: static routes from container host interfaces do not work. Documentation updated with an example
  • Fix #368: upgrading oci-archive:/ images fail because system thinks the image can be pulled from a localhost registry. Documentation has also been updated, describing various methods and how to upgrade them
  • Fix #370: despite the documentation stating containers must explicitly declare network settings, Infix v23.02 had a late regression that reverted back to the podman default: network behind a CNI bridge (firewalled and NAT:ed, hidden from the rest of the network)
  • Fix #375: k8s-logger, used for containers, does not exit properly and causes 100% CPU load when container stop or are restarted. Also in this issue: handle ip/route additions to container networks at runtime
  • Fix #384: segfault in helper function when disabling the DHCP client using no dhcp-client from the CLI
  • Fix #391 Creating VLAN interface in the CLI with edit interface vlanN does not set VLAN id to N.
  • Fix #404: lldpd should be disabled on internal interface dsa0
  • Fix #406: an overly restrictive when expression in the bridge YANG model prevented users from adding VLAN interfaces as bridge ports. E.g., creating interface eth0.10 and adding that to br0
  • Fix #412: after starting up with DHCP client enabled on any interface set dhcp-client enabled false does not bite at runtime
  • Fix #414: spelling error in infix-hardware.yang, leaf node coutry
  • Fix #415: startup-config owned by root user and group instead of admin. The file ownership is now adjusted on every boot
  • Fix #416: admin user cannot perform a factory reset with RPC using sysrepocfg tool over SSH
  • Fix bogus syslog warning about not updating /etc/motd properly
