2018-02-22bihash table size perf/scale improvementsDave Barach4-44/+84
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.

2018-02-19dpdk: Fix MTU calc for NICs that support mtu<9216Nitin Saxena1-34/+66
Problem: rte_eth_dev_set_mtu() returns with failure from ThunderX NICVF DPDK PMD driver which supports MTU less than ETHERNET_MAX_PACKET_BYTES. rte_eth_dev_set_mtu() being called twice from dpdk_lib_init(): one via dpdk_device_setup() and second in dpdk_lib_init() itself. Currently dpdk_lib_init() passes vnet_hardware_interface->max_packet_bytes as an argument to rte_eth_dev_set_mtu() without consulting dev_info.max_rx_pktlen. NICs like i4oe, ixgbe can support MTU much greater than 9216 hence its not a problem for those NICS. Fix: This patch calculates dpdk_device->port_conf.rxmode.max_rx_pkt_len, vnet_hardware_interface->max_packet_bytes and MTU by consulting dev_info.max_rx_pktlen.

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.

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>
