2018-05-04Fix format for the dst address in the STN traceMilan Lenco1-2/+2
Output string 's' was not assigned the return value of format() for the destination address, which, in case the underlying memory was moved by the realloc, resulted in an invalid memory access by the subsequent invocations of format().

2018-04-25STN: use the punt feature arcsNeale Ranns1-79/+28
Fixes: - the parsing of the packet falsely assume an ethernet header at offset 0 - it causes a frame leak Change-Id: Ib9ac9535173ed216de613baaa06d0e1dea3640ca Signed-off-by: Neale Ranns <nranns@cisco.com>

2017-11-21stn-plugin: do not assume all punted packets start with L3 header.Andrew Yourtchenko1-0/+12
Some punt scenarios (notably, involving DNS traffic) do not have the current_data set to the L3 header - as a result, chaos ensues. To tackle this, approach the parsing from the other side, and look at the hopefully remaining ethernet header to see whether the packet is IPv4 or IPv6. Verified the STN'ed TCP traffic continues to work, and that the STN'ed DNS traffic starts to work as well.

2017-10-18Plugin for IP-Address to Interface PuntingPierre Pfister1-0/+484
This plugin provides per-ip address to interface punting. When at least one rule is defined, the plugin receives all packets which destination is one of VPP's address but which was not processed by VPP (e.g., a TCP packet on a port that is not open, or a packet for a protocol which is not attached). Based on the set of configured rules, the destination address of each packet is used to send the packet on the associated interface. This plugin allows multiple containers to use VPP's TCP stack (or other features provided by VPP) while still being able to receive additional packets.
