2016-12-20dpdk: fix advance header for ip4-no-checksumSergio Gonzalez Monroy1-0/+1
Fixes: 78eeef747b19 ("Improve dpdk-input node to handle drivers not setting mbuf PTYPE") Change-Id: I94addcec2bf3097ab047e8d7e957bc983eab9add Signed-off-by: Sergio Gonzalez Monroy <sergio.gonzalez.monroy@intel.com>
2016-12-20Improve dpdk-input node to handle drivers not setting mbuf PTYPEJohn Lo5-48/+111
For drivers that do not provide dpdk rte_mbuf PTYPE information, check ethernet header Etype to acccelerate IP4 and IP6 forwarding path. Update packet trace for dpdk-input node to provide more info from DPDK rte_mbuf offload flags and packet types.

2016-12-16Fix dpdk-input check for VLAN packets including VLAN strip caseJohn Lo1-1/+16
For DPDK-16.11 or later, use packet_type to check packets with VLAN tags. For earlier versions of DPDK, keep using ol_flags but include PKT_RX_VLAN_STRIPPED bit as part of the VLAN tags check. Change-Id: Ic4ad8f04e44658dc0a99de0232fdc949cfa13e93 Signed-off-by: John Lo <loj@cisco.com>

Improve ethernet-input speed path for untagged packets to also handle L3 and other forwarding paths. In the IP4 forwarding path for untagged IP4 packets, per packet clock count in ethernet-input node is reduced to ~14 clocks from ~43 clocks.

2016-12-12ipsec: go straight to lookup after esp encryptSergio Gonzalez Monroy2-8/+8
Currently, IPsec tunnel traffic goes to ip4-input/ip6-input after esp-encrypt. It is not necessary to check that the new IP header is valid (if it is not valid then we have otehr issues). Instead, just send packets straight to ip4-lookup/ip6-lookup after esp-encrypt.

2016-12-09BFD: handle timing wheel prematurely firing eventsKlement Sekera4-69/+85
Improve handling of timeouts. Add a workaround for when timing wheel fires an event a tiny amount of time before it should actually be fired. Don't delete unneeded events at all from timing wheel, instead ignoring unexpected events. Enable the skipped BFD test, which passes now.

2016-12-09VPP-547: Fix for co-existence of HbH and RH header in Segment routing:Shwetha4-107/+457
1. sr-rewrite - SR insertion in v6 : SR RH is inserted immediately after v6 header but if hbh header is present as per RFC2460 it should immediately follow v6 header. This is fixed. 2. sr-local : v6 packet destined to a sr segment is received if hbh is present it is not handed over to sr-local for processing. fixed ip6-local handling to skip hbh as there is no register handler for hbh for now. 3. sr-replicate - update in dual of sr_rewrite to handle replicate, fixes in sr-replicate to handle presence of hbh header Change-Id: I034523a42d2fedf97134761f956ab534babb8b36 Signed-off-by: Shwetha <shwethab@cisco.com>
2016-12-09DPDK HQoS: enable vpp control plane thread connection to hqos threadJasvinder Singh2-4/+10
The vpp control plane thread generates different types of packets such as ARP, DHCP client, IPv6 RA, etc. which need to go through HQoS thread associated with the output interfaces. Therefore, this patch enables vpp main thread connection with the HQoS thread through dedicated SWQ.

The re-entrant walks were caused when the walk from an IP adj updated a fib_netry with an MPLS adj which in turn triggers a walk of the IP adj.

After a bug was found, I decided to review old vhost code.

Then in the rewrite nodes we can check this flag and not perform the TTL decrement. The switch path cost is expected to be fractions of a clock - the flags will be hot in the cache. The cehcks are necessary to due the requirements that VPP must be able to emit an IP packet with TTL=255.
