2021-07-28gre: set proper fib index for unnumbered interfaces, unset fib index before ↵Stanislav Zaikin1-0/+5
forwarding gre payload This commit introduces 2 fixes: 1) After GRE decapsulation sw_if_index[VLIB_TX] is set as fib index of GRE tunnel. But since GRE tunnel can work on v4 endpoints and have v6 payload, we need to reset it. In case we get IPv6 packet inside IPv4 GRE tunnel (or vice-versa) fib index can be (and usually is) invalid. 2) Check that ip-table and ip6-table are the same when setting interface as an unnumbered one. Also, fix for the pipe test include setting the right unnumbered interface for the pipes Type: fix Signed-off-by: Stanislav Zaikin <zstaseg@gmail.com> Change-Id: Id13d239cfdd21e0db6b1c9725f01c40d4af4d800

2018-02-15Optimize GRE Tunnel and add support for ERSPAN encapJohn Lo1-39/+44
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 Ranns1-87/+87
- 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>

2017-04-06Use thread local storage for thread indexDamjan Marion1-4/+4
This patch deprecates stack-based thread identification, Also removes requirement that thread stacks are adjacent. Finally, possibly annoying for some folks, it renames all occurences of cpu_index and cpu_number with thread index. Using word "cpu" is misleading here as thread can be migrated ti different CPU, and also it is not related to linux cpu index.

2017-04-05GRE over IPv6Ciara Loftus1-68/+252
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>
