2018-08-23ip4: rework rewrite node to use vlib_buffer_enqueue_to_next()Damjan Marion1-355/+270
- perf improvement is around 3 clock per packet - it properly prefetches ip header and rewrite area Credits to zhiyong.yang@intel.com for spotting that in some cases rewrite area is not prefetched.

2018-08-17VPP-1392: VXLAN fails with IP fragmentationOle Troan4-2/+6
Not only is it wasteful to send all fragments back through ip4-lookup, but it doesn't work with tunnel mechanisms that don't have IP enabled on their payload side. Change-Id: Ic92d95982dddaa70969a2a6ea2f98edec7614425 Signed-off-by: Ole Troan <ot@cisco.com>

2018-08-13Multiarch handling in different constructor macrosDamjan Marion1-4/+2
This significantly reduces need for ... in multiarch code. Simply constructor macros will jost create static unused entry if CLIB_MARCH_VARIANT is defined and that will be optimized out by compiler.

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. This is required because some IGMP packets are sent to the group address and not the all-routers address. All IGMP packets are sent with the router alert option.

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. Fix calculation when data is fully unaligned / on an odd byte boundary. Add a buffer alignment test vector.

2018-06-05bond: send gratuitous arp when the active slave went down in active-backup modeSteven2-14/+17
- Modify the API send_ip6_na and send_ip4_garp to take sw_if_index instead of vnet_hw_interface_t and add call to build_ethernet_rewrite to support subinterface/vlan - Add code to bonding driver to send an event to bond_process when the first interface becomes active or when the active interface is down - Create a bond_process to walk the interface and the corresponding subinterfaces to send garp/ip6_na when an event is received. - Minor cleanup in bonding/node.c Note: dpdk bonding driver does not send garp/ip6_na for subinterfaces. There is no attempt to fix it here. But the infra is now done and should be easy to add the support. Change-Id: If3ecc4cd0fb3051330f7fa11ca0dab3e18557ce1 Signed-off-by: Steven <sluong@cisco.com>
