In case iproute2 is older than version 5.11.0, released ~Feb 23, 2021,
the vrftable support is not available and the tests
contained in the following 4 test files
- srv6_end_dt4_l3vpn_test.sh
- srv6_end_dt6_l3vpn_test.sh
are failing in some kernel backports.
This is the result of one those tests in an unsupported environment:
\################################################################################
\TEST SECTION: SRv6 VPN connectivity test among hosts in the same tenant
\################################################################################
\
\ TEST: Hosts connectivity: hs-t100-1 -> hs-t100-2 (tenant 100) [FAIL]
\
\ TEST: Hosts connectivity: hs-t100-2 -> hs-t100-1 (tenant 100) [FAIL]
\
\ TEST: Hosts connectivity: hs-t200-3 -> hs-t200-4 (tenant 200) [FAIL]
\
\ TEST: Hosts connectivity: hs-t200-4 -> hs-t200-3 (tenant 200) [FAIL]
\
To amend this, check the current running iproute2 supports the vrftable
feature and, if not, just skip the entire test to avoid a failure.
v2: - remove dx[4/6] tests
- test if vrftable is available in the installed iproute2 application
v1:
https://patchwork.kernel.org/project/netdevbpf/patch/[email protected]/
- initial approach by testing DT[4/6] and DX[4/6]
- test if DT4/DT6 are available in iproute2
