From 6545716c073c88ad86458620c6dbc59ba1cd00bb Mon Sep 17 00:00:00 2001 From: Dave Barach Date: Tue, 10 Oct 2017 17:53:14 -0400 Subject: 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 Change-Id: I48c373d5c05d7108ccd814d4055caf8c75ca10b7 Signed-off-by: Dave Barach --- src/vnet/ip/ip_init.c | 3 +++ 1 file changed, 3 insertions(+) (limited to 'src/vnet/ip/ip_init.c') diff --git a/src/vnet/ip/ip_init.c b/src/vnet/ip/ip_init.c index f7635b35d0e..e181a4fdd9b 100644 --- a/src/vnet/ip/ip_init.c +++ b/src/vnet/ip/ip_init.c @@ -137,6 +137,9 @@ do { \ if ((error = vlib_call_init_function (vm, flow_classify_init))) return error; + if ((error = vlib_call_init_function (vm, dns_init))) + return error; + return error; } -- cgit 1.2.3-korg
