| # 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 |
