# End-to-end eBPF tunnel test suite
|

# The script tests BPF network tunnel implementation.
|
||
|
|
#
|
||
|
|
# Topology:
|
||
|
|
# ---------
|
||
|
|
# root namespace | at_ns0 namespace
|
||
|
|
# |
|
||
|
|
# ----------- | -----------
|
||
|
|
# | tnl dev | | | tnl dev | (overlay network)
|
||
|
|
# ----------- | -----------
|
||
|
|
# metadata-mode | native-mode

# with bpf |
|

# ---------- | ----------
|

|
|
# | veth1 | --------- | veth0 | (underlay network)
|

# ---------- peer ----------
|
||
|

#
|
||
|
|
#
|
||
|
|
# Device Configuration
|
||
|
|
# --------------------
|
||
|
|
# Root namespace with metadata-mode tunnel + BPF
|
||
|
|
# Device names and addresses:
|
||
|
|
# veth1 IP: 172.16.1.200, IPv6: 00::22 (underlay)
|
||
|
|
# tunnel dev <type>11, ex: gre11, IPv4: 10.1.1.200, IPv6: 1::22 (overlay)
|
||
|
|
#
|
||
|
|
# Namespace at_ns0 with native tunnel
|
||
|
|
# Device names and addresses:
|
||
|
|
# veth0 IPv4: 172.16.1.100, IPv6: 00::11 (underlay)
|
||
|
|
# tunnel dev <type>00, ex: gre00, IPv4: 10.1.1.100, IPv6: 1::11 (overlay)
|
||
|
|
#
|
||
|
|
#
|
||
|
|
# End-to-end ping packet flow
|
||
|
|
# ---------------------------
|
||
|
|
# Most of the tests start by namespace creation, device configuration,
|
||
|
|
# then ping the underlay and overlay network. When doing 'ping 10.1.1.100'
|
||
|
|
# from root namespace, the following operations happen:
|
||
|
|
# 1) Route lookup shows 10.1.1.100/24 belongs to tnl dev, fwd to tnl dev.
|
||
|
|
# 2) Tnl device's egress BPF program is triggered and set the tunnel metadata,
|
||
|
|
# with remote_ip=172.16.1.200 and others.
|
||
|
|
# 3) Outer tunnel header is prepended and route the packet to veth1's egress
|
||
|
|
# 4) veth0's ingress queue receive the tunneled packet at namespace at_ns0
|
||
|
|
# 5) Tunnel protocol handler, ex: vxlan_rcv, decap the packet
|
||
|
|
# 6) Forward the packet to the overlay tnl dev
