selftests/bpf: test_tunnel: Remove test_tunnel.sh
All tests from test_tunnel.sh have been migrated into test test_progs. The last test remaining in the script is the test_ipip() that is already covered in the test_prog framework by the NONE case of test_ipip_tunnel(). Remove the test_tunnel.sh script and its Makefile entry Signed-off-by: Bastien Curutchet (eBPF Foundation) <bastien.curutchet@bootlin.com> Signed-off-by: Martin KaFai Lau <martin.lau@kernel.org> Acked-by: Stanislav Fomichev <sdf@fomichev.me> Link: https://patch.msgid.link/20250303-tunnels-v2-10-8329f38f0678@bootlin.com Signed-off-by: Alexei Starovoitov <ast@kernel.org>

# 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=172.16.1.100 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
