Joachim WibergandMattias Walström 2fa5dcfea0 board/common: major refactor of udhcpc script
- New log() function replaces stdout logging
 - New set_dhcp_routes() and clr_dhcp_routes() functions
   - Set all option 121 routes with same metric
   - Set all option 3 routers with increasing metric (this is what the
     reference udhcpc scripts do, and RFC says the routers should be
     listed in order of preference ...)
   - Clearing routes must, like IP addresses, be done both by interface
     and protocol.  This refactor makes sure to delete any DHCP routes
     set on the given interface (in case options change)
 - Use resolvconf per-interface search+nameserver
 - Cache IP lease so we can ask for it back later
 - On deconfig|leasefail|nak, make sure to clean up anything that might
   be lingering from this interface.  E.g., we can get leasefail when a
   server denies our request to prolong a lease.
 - On renew|bound, refresh routes, and set search+dns + NTP servers

License Badge Coverity Status Infix - Linux <3 NETCONF

Documentation

Infix is a Linux Network Operating System (NOS) based on Buildroot, and sysrepo. A powerful mix that ease porting to different platforms, simplify long-term maintenance, and provide made-easy management using NETCONF1 (remote) or the built-in command line interface (CLI) (click the foldout for an example).

Example CLI Session

The CLI configure context is automatically generated from the loaded YANG models and their corresponding sysrepo plugins. The following is brief example of how to set the IP address of an interface:

admin@infix-12-34-56:/> configure
admin@infix-12-34-56:/config/> edit interface eth0
admin@infix-12-34-56:/config/interface/eth0/> set ipv4 <TAB>
      address     autoconf bind-ni-name      enabled
	  forwarding  mtu      neighbor
admin@infix-12-34-56:/config/interface/eth0/> set ipv4 address 192.168.2.200 prefix-length 24
admin@infix-12-34-56:/config/interface/eth0/> show
type ethernet;
ipv4 {
  address 192.168.2.200 {
    prefix-length 24;
  }
}
ipv6
admin@infix-12-34-56:/config/interface/eth0/> diff
interfaces {
  interface eth0 {
+    ipv4 {
+      address 192.168.2.200 {
+        prefix-length 24;
+      }
+    }
  }
}
admin@infix-12-34-56:/config/interface/eth0/> leave
admin@infix-12-34-56:/> show interfaces
INTERFACE       PROTOCOL   STATE       DATA

                ipv4                   192.168.2.200/24 (static)

Infix can run on many different types of architectures and boards, much thanks to Linux and Buildroot. Currently the focus is on 64-bit ARM devices, optionally with switching fabric supported by Linux switchdev. The following boards are fully supported:

  • Marvell CN9130 CRB
  • Marvell EspressoBIN
  • Microchip SparX-5i PCB135 (eMMC)

An x86_64 build is also available, primarily intended for development and testing, but can also be used for evaluation and demo purposes. For more information, see: Infix in Virtual Environments.

See the GitHub Releases page for our pre-built images. The Latest Build has the bleeding edge images, if possible we recommend using a versioned release.

For customer specific builds of Infix, see your product repository.
