2018-02-15Optimize GRE Tunnel and add support for ERSPAN encapJohn Lo12-358/+721
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.

2018-02-15SCTP: fix corrupted buffers seen in output nodeMarco Varlese4-44/+62
The issue observed in the output-node was actually caused by one of the input-node pushing buffers to the output node when not required. That is the case with the parsing/handling of incoming packets like the COOKIE_ACK, HEARTBEAT_ACK, DATA, SACK which do not require a response to be sent to the other peer. In all the mentioned cases the packets (buffers) need to be consumed and dropped instead of heading to the output-node.

This patch takes care of some refactoring, including the initialization of the timestamp to calculate the RTO, the output state-machine validation which can be enabled (disabled by default) when debugging and some clean-up of unused fields. It also addresses the requirement of Karn's algorithm when computing the RTO. Change-Id: I6b875152369bff23cad085708cec1f7e1151cfa8 Signed-off-by: Marco Varlese <marco.varlese@suse.com>

2018-02-14session: support local sessions and deprecate redirectsFlorin Coras23-496/+1277
Memfd backed shared memory segments can only be negotiated over sockets. For such scenarios, the existing redirect mechanism that establishes cut-through sessions does not work anymore as the two peer application do not share such a socket. This patch adds support for local sessions, as opposed to sessions backed by a transport connection, in a way that is almost transparent to the two applications by reusing the existing binary api messages. Moreover, all segment allocations are now entirely done through the segment manager valloc, so segment overlaps due to independent allocations previously required for redirects are completely avoided. The one notable characteristic of local sessions (cut-through from app perspective) notification messages is that they carry pointers to two event queues, one for each app peer, instead of one. For transport-backed sessions one of the queues can be inferred but for local session they cannot. Change-Id: Ia443fb63e2d9d8e43490275062a708f039038175 Signed-off-by: Florin Coras <fcoras@cisco.com>

Crash occurring With a worker thread configured and dhcp client active on an interface. When a DHCP reply packet is received, call to ethernet_get_main() from dhcp_proxy_to_client_input() was causing a crash. Replaced with a call to vnet_get_ethernet_main(). Once that was resolved, calling dhcp_client_acquire_address() from a worker thread also caused a crash. Changed so the main thread will do the address/route configuration.

2018-02-08acl-plugin: add whitelisted ethertype mode (VPP-1163)Andrew Yourtchenko5-5/+308
Currently, ACL plugin largely does not care about the ethertypes other than 0x0800 (IPv4) and 0x86dd (IPv6), the only exception being 0x0806 (ARP), which is dealt with by the MACIP ACLs. The other ethertypes in L2 mode are just let through. This adds a new API message acl_interface_set_etype_whitelist, which allows to flip the mode of a given interface into "ethertype whitelist mode": the caller of this message must supply the two lists (inbound and outbound) of the ethertypes that are to be permitted, the rest of the ethertypes are dropped. The whitelisting for a given interface and direction takes effect only when a policy ACL is also applied. This operates on the same classifier node as the one used for dispatching the policy ACL, thus, if one wishes for most of the reasonable IPv4 deployments to continue to operate within the whitelist mode, they must permit ARP ethertype (0x0806) The empty list for a given direction resets the processing to allow the unknown ethertypes. So, if one wants to just permit the IPv4 and IPv6 and nothing else, one can add their ethertypes to the whitelist. Add the "show acl-plugin interface" corresponding outputs about the whitelists, vat command, and unittests.

This adds an action "2" which means "add also egress filtering rules for this MACIP ACL.

2018-02-07classifier-based ACL: refactor + add output ACLAndrew Yourtchenko19-502/+651
For implementation of MACIP ACLs enhancement (VPP-1088), an outbound classifier-based ACL would be needed. There was an existing incomplete code for outbound ACLs, it looked almost exact copy of input ACLs, minus the various enhancements, trying to sync that code seemed error-prone and cumbersome to maintain in the longer run. This change refactors the input+output ACLs processing into a unified routine (thus any changes will have effect on both), and also adds the API to set the output interface ACL, with the same format and semantics as the existing input one (except working on output ACL of course). WARNING: IP outbound ACL in L3 mode clobbers the ip.* fields in the vnet_buffer_opaque_t, since the code is using l2_classify.* The net_buffer (p0)->ip.save_rewrite_length is rescued into l2_classify.pad.l2_len, and used to rewind the header in case of drop, so that ipX_drop prints something sensible.
