2017-01-31Add vxlan-bypass feature to IP6 forwarding pathJohn Lo2-1/+12
Add vxlan-bypass feature which can be enabled on the IP6 underlay interface which receive VXLAN packets to accelerate VXLAN decap processing. The CLI to enable/disable it is: set interface ip6 vxlan-bypass <interface> [del] The vxlan-bypass feature is already supported on the IP4 underlay interface. The CLI to enable/disable it is: set interface ip vxlan-bypass <interface> [del] Move vxlan-bypass API/CLI support code from decap.c to vxlan.c. Also fixed two issues in the VXLAN decap path in the vxlan-input node: 1. Add verification of VXLAN packet FIB index with the encap-vrf-id of the VXLAN tunnel. 2. Fix checking of VXLANoIPv6 packet mcast DIP against that of the IP6 mcast VXLAN tunnel. Change-Id: I2bad4074a468c48fbb8bb5ac64f6437190756ed2 Signed-off-by: John Lo <loj@cisco.com>
2017-01-30VPP-621: ping: ICMP echo data size must be bounded by VLIB_BUFFER_DATA_SIZE ↵Andrew Yourtchenko2-29/+46
minus headers. Before the commit 878c6098 the VLIB_BUFFER_DATA_SIZE was different depending on whether building "vpp" or "vpp_lite", resulting in an overrun in vpp_lite build. Avoid the hardcoded value and make the upper bound for ICMP echo data size dependent on the buffer size.

2017-01-27IP Multicast FIB (mfib)Neale Ranns11-489/+840
- IPv[46] mfib tables with support for (*,G/m), (*,G) and (S,G) exact and longest prefix match - Replication represented via a new replicate DPO. - RPF configuration and data-plane checking - data-plane signals sent to listening control planes. The functions of multicast forwarding entries differ from their unicast conterparts, so we introduce a new mfib_table_t and mfib_entry_t objects. However, we re-use the fib_path_list to resolve and build the entry's output list. the fib_path_list provides the service to construct a replicate DPO for multicast. 'make tests' is added to with two new suites; TEST=mfib, this is invocation of the CLI command 'test mfib' which deals with many path add/remove, flag set/unset scenarios, TEST=ip-mcast, data-plane forwarding tests. Updated applications to use the new MIFB functions; - IPv6 NS/RA. - DHCPv6 unit tests for these are undated accordingly.

2017-01-24ping: fix double-free crash under VMWare hypervisorAndrew Yourtchenko1-2/+2
bi0 retrieval from the ping reply events vector was incorrectly done always from the first element. For TBD reason the sending of the ping requests under VMWare was batched, as a result the replies arrive close enough to make the events arrive as an array, which exposed this bug. KVM never exhibited this behavior, which explains not seeing this issue there. Change-Id: I485d6f983571e25baa9407c21ef604937586d8bd Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>
