** Description changed:
- Issue found on 5.4.0-1025.25~18.04.1, this issue was not spotted before
- fixing the false-negative return value of this rtnetlink.sh test (bug
- 1890136)
+ [ Impact ]
+ When running the net/rtnetlink.sh selftest from v5.4 on older Ubuntu releases
(e.g. Bionic 18.04), some of the iproute2 CLI options are not available causing
the testcase to fail.
+
+ [ Fix ]
+ SAUCE patch to detect whether some options not present on older iproute2
versions are available, skipping or adapting the tests.
+
+ [ Test ]
+ Run net/rtnetlink.sh on 5.4 kernels with both Focal and Bionic userspace. The
test should complete without introducing regressions on Focal and without
breaking on Bionic.
+
+ [ Where problems could occur ]
+ If the checks for the available interfaces are not done correctly, we could
end up having a smaller coverage on Focal or the tests would still break in
Bionic.
