Merge branch 'bpf-tunnel-metadata-selftests'
William Tu says:
====================
The patch series provide end-to-end eBPF tunnel testsute. A common topology
is created below for all types of tunnels:
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 (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 (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
Test Cases
-----------------------------
Tunnel Type | BPF Programs
-----------------------------
GRE: gre_set_tunnel, gre_get_tunnel

ERSPAN: erspan_set_tunnel, erspan_get_tunnel
IP6ERSPAN: ip4ip6erspan_set_tunnel, ip4ip6erspan_get_tunnel
VXLAN: vxlan_set_tunnel, vxlan_get_tunnel
IP6VXLAN: ip6vxlan_set_tunnel, ip6vxlan_get_tunnel
GENEVE: geneve_set_tunnel, geneve_get_tunnel

# 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 (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 (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
