2018-07-21fix IP directed broadcast node declarationsMatthew Smith2-2/+2
The dev build ('make build') was failing because ip4_rewrite_bcast() and ip6_rewrite_bcast() are declared static and were not referenced. The node functions that were set for directed broadcast rewrite: ip4_rewrite_bcast_node - ip4_rewrite() ip6_rewrite_bcast_node - ip6_rewrite() Changed to: ip4_rewrite_bcast_node - ip4_rewrite_bcast() ip6_rewrite_bcast_node - ip6_rewrite_bcast() The release build ('make build-release') succeeds because there is a VLIB_NODE_FUNCTION_MULTIARCH() call referencing the function. That macro is empty for dev builds. Change-Id: I2a05f00ca43d0eae8ff2e3026991e69917003fe1 Signed-off-by: Matthew Smith <mgsmith@netgate.com>

2018-07-14Improve IP4 ARP and IP6 ND Events Notificationv18.10-rc0John Lo1-1/+7
For L2 ARP termination, use both brodcast ARP request and reply packets to provide MAC/IP binding events. For IP4/IP6 neighbor adress resolution, send resolution events if there is an address resolution attemp with a static neighbor entry where both IP and MAC matches. This allow probe of an IP neighbor with a static entry to confirm it is responding with a reply matching that of the static entry.

and a new ip4-options node, inserted between ip4-input and ip4-punt, that checks for IP-router-alert option + IGMP combination and sends the packet to the ip4-local.

2018-06-19ip checksum multiarch support, cleanupDave Barach2-109/+91
When computing tcp/udp checksums across large amounts of data - e.g. when NIC h/w checksum offload is not available - it's worth providing arch-dependent code; if only to compile the code w/ -O3.
