Gatekeeper currently supports some Linux applications and services through the KNI:

• ARP and ND, since Gatekeeper intercepts ARP/ND requests from the KNI and replies using the Gatekeeper L2 resolution cache
• ICMP Ping (IPv4 and IPv6), since Gatekeeper passes ping replies to the KNI
• BGP, since Gatekeeper passes BGP packets to the KNI

To support other tools and applications, we can add a

Background

ICMP messages are used by network devices, including routers, to send error messages and operational information indicating success or failure when communicating with another IP address. Examples include errors indicating when a requested service is not available or when a host or router could not be reached. We've

Current Behavior
If an NF tries to send a message to another NF using the onvm_nflib_send_msg_to_nf() function it will allocate memory to store the message and then enqueue the message for the other NF. If the enqueue fails (because the destination NF's ring is full), then the allocated memory will never be freed.

Compilation of YAStack can be optimized by pre-compiling source code that does not depend on DPDK. This can help build the image faster since now only DPDK and dependent code will have to be compiled.
