4# End-to-end eBPF tunnel test suite
5# The script tests BPF network tunnel implementation.
6#
7# Topology:
8# ---------
9# root namespace | at_ns0 namespace
10# |
11# ----------- | -----------
12# | tnl dev | | | tnl dev | (overlay network)
13# ----------- | -----------
14# metadata-mode | native-mode
15# with bpf |
16# |
17# ---------- | ----------
18# | veth1 | --------- | veth0 | (underlay network)
19# ---------- peer ----------
20#
21#
22# Device Configuration
23# --------------------
24# Root namespace with metadata-mode tunnel + BPF
25# Device names and addresses:
26# veth1 IP: 172.16.1.200, IPv6: 00::22 (underlay)
27# tunnel dev <type>11, ex: gre11, IPv4: 10.1.1.200, IPv6: 1::22 (overlay)
28#
29# Namespace at_ns0 with native tunnel
30# Device names and addresses:
31# veth0 IPv4: 172.16.1.100, IPv6: 00::11 (underlay)
32# tunnel dev <type>00, ex: gre00, IPv4: 10.1.1.100, IPv6: 1::11 (overlay)
33#
34#
35# End-to-end ping packet flow
36# ---------------------------
37# Most of the tests start by namespace creation, device configuration,
38# then ping the underlay and overlay network. When doing 'ping 10.1.1.100'
39# from root namespace, the following operations happen:
40# 1) Route lookup shows 10.1.1.100/24 belongs to tnl dev, fwd to tnl dev.
41# 2) Tnl device's egress BPF program is triggered and set the tunnel metadata,
42# with remote_ip=172.16.1.100 and others.
43# 3) Outer tunnel header is prepended and route the packet to veth1's egress
44# 4) veth0's ingress queue receive the tunneled packet at namespace at_ns0
45# 5) Tunnel protocol handler, ex: vxlan_rcv, decap the packet
46# 6) Forward the packet to the overlay tnl dev
