kernel/tools/testing/selftests/net/vrf_route_leaking.sh, branch linux-6.2.yHosts the 0x221E linux distro kernel.https://universe.0xinfinity.dev/distro/kernel/atom?h=linux-6.2.y2020-10-15T00:14:28Zselftests: Add VRF route leaking tests2020-10-15T00:14:28ZMichael Jeansonmjeanson@efficios.com2020-10-12T14:50:16Zurn:sha1:1a01727676a87945bd6b9796fc5ee894c24b4fe2
The objective of the tests is to check that ICMP errors generated while
crossing between VRFs are properly routed back to the source host.
The first ttl test sends a ping with a ttl of 1 from h1 to h2 and parses the
output of the command to check that a ttl expired error is received.
The second ttl test runs traceroute from h1 to h2 and parses the output to
check for a hop on r1.
The mtu test sends a ping with a payload of 1450 from h1 to h2, through
r1 which has an interface with a mtu of 1400 and parses the output of the
command to check that a fragmentation needed error is received.
[ The IPv6 MTU test still fails with the symmetric routing setup. It
appears to be caused by source address selection picking ::1. Fixing
this is beyond the scope of this series. ]
