2018-07-18Add config option to use dlmalloc instead of mheapDave Barach1-0/+4
Configure w/ --enable-dlmalloc, see .../build-data/platforms/vpp.mk src/vppinfra/dlmalloc.[ch] are slightly modified versions of the well-known Doug Lea malloc. Main advantage: dlmalloc mspaces have no inherent size limit. Change-Id: I19b3f43f3c65bcfb82c1a265a97922d01912446e Signed-off-by: Dave Barach <dave@barachs.net>
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>

2018-05-11Periodic scan and probe of IP neighbors to maintain neighbor poolsJohn Lo6-5/+516
Scan IPv4 and IPv6 neigbor pool entries once a minute to keep them up to date. The neighbor of an entry is probed if its time-stamp is older than 1 minute. If the neighbor respond, its time-stamp will be updated. If there is no response from a neighbor, its entry will be deleted when the time-stamp of the entry become more than 4 minutes old. Static neighbor entries are not probed nor deleted. Implemented CLI and API to enable and disable priodic scan of IPv4, IPv6 or both types of IP neighbors. CLI is "ip scan-neighbor" and API is "ip_scan_neighbor_enable_disable". Other IP neighbor scan parameters can also be changed from their defaults via the CLI/API.
