2017-11-27vlib: make vlib_buffer_alloc inline functionDamjan Marion1-1/+1
Currently, every alloc involves callback function call. With this change callback function is called only if there is no empty buffers on the free list. Change-Id: I2238c19ece7ce182c49ba0f2485add52f335f3b6 Signed-off-by: Damjan Marion <damarion@cisco.com>

2017-10-13VPP-1027: DNS name resolverDave Barach6-0/+2940
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 Change-Id: I48c373d5c05d7108ccd814d4055caf8c75ca10b7 Signed-off-by: Dave Barach <dave@barachs.net>
