The key components for such VPNs are: a) SRv6 Encap behavior, +# b) SRv6 End.DX4 behavior. +# +# To explain how an IPv4 L3 VPN based on SRv6 works, let us briefly consider an +# example where, within the same domain of tenant 100, the host hs-1 pings +# the host hs-2. +# +# First of all, L2 reachability of the host hs-2 is taken into account by +# the router rt-1 which acts as an arp proxy. +# +# When the host hs-1 sends an IPv4 packet destined to hs-2, the router rt-1 +# receives the packet on the internal veth-t100 interface, rt-1 contains the +# SRv6 Encap route for encapsulating the IPv4 packet in a IPv6 plus the Segment +# Routing Header (SRH) packet. This packet is sent through the (IPv6) core +# network up to the router rt-2 that receives it on veth0 interface. +# +# The rt-2 router uses the 'localsid' routing table to process incoming +# IPv6+SRH packets which belong to the VPN of the tenant 100. For each of these +# packets, the SRv6 End.DX4 behavior removes the outer IPv6+SRH headers and +# routs the packet to the specified nexthop. Afterwards, the packet is sent to +# the host hs-2 through the veth-t100 interface. +# +# The ping response follows the same processing but this time the role of rt-1 +# and rt-2 are swapped. +# +# And when net.netfilter.nf_hooks_lwtunnel is set to 1 in rt-1 or rt-2, and a +# rpfilter iptables rule is added, SRv6 packets will go through netfilter PREROUTING +# hooks. +# +# +# +-------------------+ +-------------------+ +# | | | | +# | hs-1 netns | | hs-2 netns | +# | | | | +# | +-------------+ | | +-------------+ | +# | | veth0 | | | | veth0 | | +# | | 10.0.0.1/24 | | | | 10.0.0.2/24 | | +# | +-------------+ | | +-------------+ | +# | . | | . | +# +-------------------+ +-------------------+ +# . . +# . . +# . . +# +-----------------------------------+ +-----------------------------------+ +# | . | | . | +# | +---------------+ | | +---------------- | +# | | veth-t100 | | | | veth-t100 | | +# | | 10.0.0.11/24 | +----------+ | | +----------+ | 10.0.0.22/24 | | +# | +-------+-------+ | route | | | | route | +-------+-------- | +# | | table | | | | table | | +# | +----------+ | | +----------+ | +# | +--------------+ | | +--------------+ | +# | | veth0 | | | | veth0 | | +# | | 2001:11::1/64 |.|...|.| 2001:11::2/64 | | +# | +--------------+ | | +--------------+ | +# | | | | +# | rt-1 netns | | rt-2 netns | +# | | | | +# +-----------------------------------+ +-----------------------------------+ +# +# ~~~~~~~~~~~~~~~~~~~~~~~~~ +# | Network configuration | +# ~~~~~~~~~~~~~~~~~~~~~~~~~ +# +# rt-1: localsid table +# +----------------------------------------------------------------+ +# |SID |Action | +# +----------------------------------------------------------------+ +# |fc00:21:100::6004|apply SRv6 End.DX4 nh4 10.0.0.1 dev veth-t100 | +# +----------------------------------------------------------------+ +# +# rt-1: route table +# +---------------------------------------------------+ +# |host |Action | +# +---------------------------------------------------+ +# |10.0.0.2 |apply seg6 encap segs fc00:12:100::6004| +# +---------------------------------------------------+ +# |10.0.0.0/24|forward to dev veth_t100 | +# +---------------------------------------------------+ +# +# +# rt-2: localsid table +# +---------------------------------------------------------------+ +# |SID |Action | +# +---------------------------------------------------------------+ +# |fc00:12:100::6004|apply SRv6 End.DX4 nh4 10.0.0.2 dev veth-t100| +# +---------------------------------------------------------------+ +# +# rt-2: route table +# +---------------------------------------------------+ +# |host |Action | +# +---------------------------------------------------+ +# |10.0.0.1 |apply seg6 encap segs fc00:21:100::6004| +# +---------------------------------------------------+ +# |10.0.0.0/24|forward to dev veth_t100 | +# +---------------------------------------------------+ +# + +# Kselftest framework requirement - SKIP code is 4. +ksft_skip=4 + +readonly IPv6_RT_NETWORK=2001:11 +readonly IPv4_HS_NETWORK=10.0.0 +readonly SID_LOCATOR=fc00 + +PING_TIMEOUT_SEC=4 + +ret=0 + +PAUSE_ON_FAIL=${PAUSE_ON_FAIL:=no} + +log_test() +{ + local rc=$1 + local expected=$2 + local msg="$3" + + if [ ${rc} -eq ${expected} ];

This packet is sent through the (IPv6) core +# network up to the router rt-2 that receives it on veth0 interface. +# +# The rt-2 router uses the 'localsid' routing table to process incoming +# IPv6+SRH packets which belong to the VPN of the tenant 100. For each of these +# packets, the SRv6 End.DX4 behavior removes the outer IPv6+SRH headers and +# routs the packet to the specified nexthop. Afterwards, the packet is sent to +# the host hs-2 through the veth-t100 interface. +# +# The ping response follows the same processing but this time the role of rt-1 +# and rt-2 are swapped. +# +# And when net.netfilter.nf_hooks_lwtunnel is set to 1 in rt-1 or rt-2, and a +# rpfilter iptables rule is added, SRv6 packets will go through netfilter PREROUTING +# hooks. +# +# +# +-------------------+ +-------------------+ +# | | | | +# | hs-1 netns | | hs-2 netns | +# | | | | +# | +-------------+ | | +-------------+ | +# | | veth0 | | | | veth0 | | +# | | cafe::1/64 | | | | cafe::2/64 | | +# | +-------------+ | | +-------------+ | +# | . | | . | +# +-------------------+ +-------------------+ +# . . +# . . +# . . +# +-----------------------------------+ +-----------------------------------+ +# | . | | . | +# | +---------------+ | | +---------------- | +# | | veth-t100 | | | | veth-t100 | | +# | | cafe::11/64 | +----------+ | | +----------+ | cafe::22/64 | | +# | +-------+-------+ | route | | | | route | +-------+-------- | +# | | table | | | | table | | +# | +----------+ | | +----------+ | +# | +--------------+ | | +--------------+ | +# | | veth0 | | | | veth0 | | +# | | 2001:11::1/64 |.|...|.| 2001:11::2/64 | | +# | +--------------+ | | +--------------+ | +# | | | | +# | rt-1 netns | | rt-2 netns | +# | | | | +# +-----------------------------------+ +-----------------------------------+ +# +# ~~~~~~~~~~~~~~~~~~~~~~~~~ +# | Network configuration | +# ~~~~~~~~~~~~~~~~~~~~~~~~~ +# +# rt-1: localsid table +# +----------------------------------------------------------------+ +# |SID |Action | +# +----------------------------------------------------------------+ +# |fc00:21:100::6004|apply SRv6 End.DX6 nh6 cafe::1 dev veth-t100 | +# +----------------------------------------------------------------+ +# +# rt-1: route table +# +---------------------------------------------------+ +# |host |Action | +# +---------------------------------------------------+ +# |cafe::2 |apply seg6 encap segs fc00:12:100::6004| +# +---------------------------------------------------+ +# |cafe::/64 |forward to dev veth_t100 | +# +---------------------------------------------------+ +# +# +# rt-2: localsid table +# +---------------------------------------------------------------+ +# |SID |Action | +# +---------------------------------------------------------------+ +# |fc00:12:100::6004|apply SRv6 End.DX6 nh6 cafe::2 dev veth-t100 | +# +---------------------------------------------------------------+ +# +# rt-2: route table +# +---------------------------------------------------+ +# |host |Action | +# +---------------------------------------------------+ +# |cafe::1 |apply seg6 encap segs fc00:21:100::6004| +# +---------------------------------------------------+ +# |cafe::/64 |forward to dev veth_t100 | +# +---------------------------------------------------+ +# + +# Kselftest framework requirement - SKIP code is 4. +ksft_skip=4 + +readonly IPv6_RT_NETWORK=2001:11 +readonly IPv6_HS_NETWORK=cafe +readonly SID_LOCATOR=fc00 + +PING_TIMEOUT_SEC=4 + +ret=0 + +PAUSE_ON_FAIL=${PAUSE_ON_FAIL:=no} + +log_test() +{ + local rc=$1 + local expected=$2 + local msg="$3" + + if [ ${rc} -eq ${expected} ];
