2018-06-11tcp: cleanup connection/session fixesFlorin Coras9-50/+73
- Cleanup session state after last ack and avoid using a cleanup timer. - Change session cleanup to free the session as opposed to waiting for delete notify. - When in close-wait, postpone sending the fin on close until all outstanding data has been sent. - Don't flush rx fifo unless in closed state Change-Id: Ic2a4f0d5568b65c83f4b55b6c469a7b24b947f39 Signed-off-by: Florin Coras <fcoras@cisco.com>
2018-06-11udp: fix for multiple workers and add testFlorin Coras5-7/+24
Since the main thread is not used for session polling anymore, when vpp is started with multiple wokers, allocate connections on the first. Also add a simple udp make test. Change-Id: Id869f5d89e0fced51048f0384fa86a5022258b7c Signed-off-by: Florin Coras <fcoras@cisco.com>
2018-06-11MTU: Software interface / Per-protocol MTU supportOle Troan27-126/+332
This patch separates setting of hardware interfaec and software interface MTU. Software MTU is L2 payload MTU (i.e. not including L2 header). Per-protocol MTU for IPv4, IPv6 and MPLS can also be set. Currently only IP4, IP6 are enabled in adjacency / rewrite code. Documentation in src/vnet/MTU.md Change-Id: Iee2fd6f0bbc8210748dd8e073ab9fab87d323690 Signed-off-by: Ole Troan <ot@cisco.com>

2018-06-05bond: send gratuitous arp when the active slave went down in active-backup modeSteven8-31/+107
- Modify the API send_ip6_na and send_ip4_garp to take sw_if_index instead of vnet_hw_interface_t and add call to build_ethernet_rewrite to support subinterface/vlan - Add code to bonding driver to send an event to bond_process when the first interface becomes active or when the active interface is down - Create a bond_process to walk the interface and the corresponding subinterfaces to send garp/ip6_na when an event is received. - Minor cleanup in bonding/node.c Note: dpdk bonding driver does not send garp/ip6_na for subinterfaces. There is no attempt to fix it here. But the infra is now done and should be easy to add the support. Change-Id: If3ecc4cd0fb3051330f7fa11ca0dab3e18557ce1 Signed-off-by: Steven <sluong@cisco.com>

2018-06-01session: improve disconnect handlingFlorin Coras3-11/+37
If the caller is the session owning thread or the main thread with a worker barrier sync (cli/api) add an event to the pending disconnects vector in the session node and entirely avoid using the event queue. Useful for bursts of disconnects (like an app detach). If disconnects come from a processes, be willing to retry enqueueing the disconnect to the event queue multiple times.

2018-05-27VPP-1294: add missing feature arc constraintDave Barach5-51/+114
the ip4-dhcp-client-detect feature MUST run prior to nat44-out2in, or inbound dhcp broadcast packets will be dropped. Certain dhcp servers answer lease renewal dhcp-request packets with broadcast dhcp-acks, leading to unrecoverable lease loss. In detail, this constraint: VNET_FEATURE_INIT (ip4_snat_out2in, static) = { .arc_name = "ip4-unicast", .node_name = "nat44-out2in", .runs_after = VNET_FEATURES ("acl-plugin-in-ip4-fa"), }; doesn't get the job done: ip4-unicast: [17] nat44-out2in [23] ip4-dhcp-client-detect [26] ip4-not-enabled Add a proper constraint: VNET_FEATURE_INIT (ip4_snat_out2in, static) = { .arc_name = "ip4-unicast", .node_name = "nat44-out2in", .runs_after = VNET_FEATURES ("acl-plugin-in-ip4-fa", "ip4-dhcp-client-detect"), }; and the interface feature order is OK, at least in this regard: ip4-unicast: [17] ip4-dhcp-client-detect [18] nat44-out2in [26] ip4-not-enabled We need to carefully audit (especially) the ip4-unicast feature arc, which has [gasp] 37 features on it!

2018-05-25bond: performance harvestingSteven4-133/+183
- hash is great. But it is a bit too slow for the DP. Use direct array indexing to quickly retrieve the slave interface. - the algorithm used by flow hash is great. But it is a bit too slow for the DP. Use l2_hash_hash() extracted from lb_hash.h which ECMP is using. It makes use of intrinsic crc32 instruction set. - shortcut modulo arithmetic when the operand is 2**x (where x up to 4) to avoid division instruction. - special case for link count == 1 in bond_tx_fn() - use clib_mem_unaligned to access data for the packet to avoid alignment error - Fix some typos for packet tracing.
