2019-03-29SPAN: Add pending frame on current thread, not on mainIgor Mikhailov (imichail)1-6/+5
Previously, all frames were put for next node on the main thread, even if the execution was happening on a worker thread. Also, refactor to use API function vnet_get_main() Change-Id: Ibefb1b3871563a78aa30352a37b9216537e15bf7 Signed-off-by: Igor Mikhailov (imichail) <imichail@cisco.com>

2018-04-25span: crash in span_mirror [VPP-1254]Steven1-2/+7
It is possible for span-input to get call with sw_if_index which is greater than sm->interfaces and crashes in span_mirror () in the following line span_interface_t *si0 = vec_elt_at_index (sm->interfaces, sw_if_index0); For example, span-input mirrors a main interface as source, it may actually get call for traffic coming in from the subinterface and crashes. The fix is simply to check if sw_if_index >= vec_len (sm->interfaces) and punt if it is.

2018-02-15Optimize GRE Tunnel and add support for ERSPAN encapJohn Lo1-3/+12
Change GRE tunnel to use the interface type where the same encap node is used as output node for all GRE tunnels, instead of having dedicated output and tx node for each tunnel. This allows for more efficient tunnel creation and deletion at scale tested at 1000's of GRE tunnels. Add support for ERSPAN encap as another tunnel type, in addition to the existing L3 and TEB types. The GRE ERSPAN encap supported is type 2 thus GRE encap need to include sequence number and GRE- ERSPAN tunnel can be created with user secified ERSPAN session ID. The GRE tunnel lookup hash key is updated to inclue tunnel type and session ID, in addition to SIP/DIP and FIB index. Thus, GRE-ERSPAN tunnel can be created, with the appropriate session ID, to be used as output interface for SPAN config to send mirrored packets. Change interface naming so that all GRE tunnels, irrespective of tunnel type, uses "greN" where N is the instance number. Removed interface reuse on tunnel creation and deletion to enable unfied tunnel interface name. Add support of user specified instance on GRE tunnel creation. Thus, N in the "greN" interface name can optionally be specified by user via CLI/API. Optimize GRE tunnel encap DPO stacking to bypass load-balance DPO node since packet output on GRE tunnel always belong to the same flow after 5-tupple hash.
