VPP-1027: DNS name resolver
This patch is a plausible first-cut, suitable for initial testing by
vcl (host stack client library).
Main features;
- recursive name resolution
- multiple ip4/ip6 name servers
- cache size limit enforcement
- currently limited to 65K
- ttl / aging
- static mapping support
- show / clear / debug CLI commands
Binary APIs provided for the following:
- add/delete name servers
- enable/disable the name cache
- resolve a name
To Do list:
- Respond to ip4/ip6 client DNS requests (vs. binary API requests)
- Perf / scale tuning
- map pending transaction ids to pool indices, so the cache
can (greatly) exceed 65K entries
- Security improvements
- Use unpredictable dns transaction IDs, related to previous item
- Make sure that response-packet src ip addresses match the server
- Add binary APIs
- deliver raw response data to clients
- control recursive name resolution
- Documentation
