- common types on the API - endpoints keyed in various ways for DP lookup - conparison functions for VPP IP address types Change-Id: If7ec0bbc5cea71fd0983fe78987d147ec1bd7ec8 Signed-off-by: Neale Ranns <neale.ranns@cisco.com>
2018-02-15Optimize GRE Tunnel and add support for ERSPAN encapJohn Lo1-2/+8
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.

2017-12-16GRE tunnel key includes the FIB tableNeale Ranns1-0/+19
- GRE tunnels with the same src,dst addresses are not the same tunnel - Two data-plane improvements: - the cached key was never updated and so useless - no need to dereference the tunnel's HW interface to get the sw_if_index Change-Id: I2f2ea6e08c759a810b753cec22c497e921a2ca01 Signed-off-by: Neale Ranns <nranns@cisco.com>

2017-09-11FIB table add/delete APINeale Ranns1-2/+6
part 2; - this adds the code to create an IP and MPLS table via the API. - but the enforcement that the table must be created before it is used is still missing, this is so that CSIT can pass. Change-Id: Id124d884ade6cb7da947225200e3bb193454c555 Signed-off-by: Neale Ranns <nranns@cisco.com>

2017-04-05GRE over IPv6Ciara Loftus1-7/+142
Refactors the GRE node to work with both IPv4 and IPv6 transports. Note that this changes the binary configuration API to support both address families; each address uses the same memory for either address type and a flag to indicate which is in use. The CLI and VAT syntax remains unchanged; the code detects whether an IPv4 or an IPv6 address was given. Configuration examples: IPv4 CLI: create gre tunnel src 192.168.1.1 dst 192.168.1.2 IPv6 CLI: create gre tunnel src 2620:124:9000::1 dst 2620:124:9000::2 IPv4 VAT: gre_add_del_tunnel src 192.168.1.1 dst 192.168.1.2 IPv6 VAT: gre_add_del_tunnel src 2620:124:9000::1 dst 2620:124:9000::2 Change-Id: Ica8ee775dc101047fb8cd41617ddc8fafc2741b0 Signed-off-by: Ciara Loftus <ciara.loftus@intel.com>

2016-12-23make test: improve handling of packet capturesKlement Sekera1-19/+14
Perform accounting of expected packets based on created packet infos. Use this accounting info to automatically expect (and verify) the correct number of packets to be captured. Automatically retry the read of the capture file if scapy raises an exception while doing so to handle rare cases when capture file is read while only partially written during busy wait. Don't fail assert_nothing_captured if only junk packets arrived. Change-Id: I16ec2e9410ef510d313ec16b7e13c57d0b2a63f5 Signed-off-by: Klement Sekera <ksekera@cisco.com>
2016-12-19make test: filter IPv6 RAs out by defaultKlement Sekera1-14/+1
Most of the test cases are not interested in IPv6 Router Alerts, so change the default behaviour of get_capture to filter out these packets with the possibility of turning the filtering off, for test cases which are interested in the RAs.

2016-12-16make test: improve robustness and performanceKlement Sekera1-39/+23
Introduce an API which asserts empty capture for interface. Throw exception in old API if the capture does not exist, thus making it clear if the test expects packets to arrive or not. Improve performance by not doing sleeps after starting the packet generator, rather lazily deleting captures when needed. Fix wrong usage of packet.show() in various tests.
