[bpf-next,v2,10/10] selftests/bpf: test_tunnel: Remove test_tunnel.sh

Commit Message

Bastien Curutchet (eBPF Foundation) March 3, 2025, 8:22 a.m. UTC

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

-# 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
