2018-02-26SCTP: Handle a COOKIE ECHO/ACK when a TCB ExistsMarco Varlese4-17/+146
This patch addresses the requirements depicted in section 5.2.4 of the RFC 4960. It also takes care of handling the ERROR chunk and obviously the STALE COOKIE error. Change-Id: I6b88a9371546b18a52abac22f7c593a5f16be838 Signed-off-by: Marco Varlese <marco.varlese@suse.com>
2018-02-26SCTP: handle INIT corner-case handlingMarco Varlese4-5/+215
As per RFC4960 the INIT chunk could be received in unexpected scenarios and - depending on the state of the internal state-machine - the INIT chunk requires different treatment. This patch addresses section 5.2.1 and 5.2.2 of the RFC4960. Change-Id: Ib23ef490c6a5ca3da6c46a9584b75e7577cb7042 Signed-off-by: Marco Varlese <marco.varlese@suse.com>

2018-02-25SCTP: fix connection memory corruptionMarco Varlese4-14/+23
A bug was found when multiple SCTP connections were being opened to the same SCTP server. This patch addresses that problem, removing the use of the 'parent' pointer approach for sub-connection and saving instead within the sub-connection itself the ID representing its position. That facilitates pointer-arithmetic to be computed in the get_connection_from_transport(). Change-Id: Iaa1f4efc501590be1c93e42fd6fe3d6e02f635eb Signed-off-by: Marco Varlese <marco.varlese@suse.com>

Directly allocate and carve cache-line-aligned chunks of virtual memory. To a first approximation, bihash wasn't using clib_mem_free(...). We eliminate mheap object header/trailers, which improves space efficiency. We also eliminate the 4gb bihash table size limit. An 8_8 bihash w/ 100 million random entries uses 3.8 Gbytes.

2018-02-15Optimize GRE Tunnel and add support for ERSPAN encapJohn Lo10-346/+691
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.

2018-02-14session: support local sessions and deprecate redirectsFlorin Coras18-447/+1180
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>

2018-02-12Fix DHCP client crash with worker threadsMatthew Smith3-51/+56
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.
