selftests: fib_nexthops: Add test cases for FDB status change
Add the following test cases for both IPv4 and IPv6: * Can change from FDB nexthop to non-FDB nexthop and vice versa. * Can change FDB nexthop address while in a group. * Cannot change from FDB nexthop to non-FDB nexthop and vice versa while in a group. Output without "nexthop: Forbid FDB status change while nexthop is in a group": # ./fib_nexthops.sh -t "ipv6_fdb_grp_fcnal ipv4_fdb_grp_fcnal" IPv6 fdb groups functional -------------------------- [...] TEST: Replace FDB nexthop to non-FDB nexthop [ OK ] TEST: Replace non-FDB nexthop to FDB nexthop [ OK ] TEST: Replace FDB nexthop address while in a group [ OK ] TEST: Replace FDB nexthop to non-FDB nexthop while in a group [FAIL] TEST: Replace non-FDB nexthop to FDB nexthop while in a group [FAIL] [...] IPv4 fdb groups functional -------------------------- [...] TEST: Replace FDB nexthop to non-FDB nexthop [ OK ] TEST: Replace non-FDB nexthop to FDB nexthop [ OK ] TEST: Replace FDB nexthop address while in a group [ OK ] TEST: Replace FDB nexthop to non-FDB nexthop while in a group [FAIL] TEST: Replace non-FDB nexthop to FDB nexthop while in a group [FAIL] [...] Tests passed: 36 Tests failed: 4 Tests skipped: 0 Output with "nexthop: Forbid FDB status change while nexthop is in a group": # ./fib_nexthops.sh -t "ipv6_fdb_grp_fcnal ipv4_fdb_grp_fcnal" IPv6 fdb groups functional -------------------------- [...] TEST: Replace FDB nexthop to non-FDB nexthop [ OK ] TEST: Replace non-FDB nexthop to FDB nexthop [ OK ] TEST: Replace FDB nexthop address while in a group [ OK ] TEST: Replace FDB nexthop to non-FDB nexthop while in a group [ OK ] TEST: Replace non-FDB nexthop to FDB nexthop while in a group [ OK ] [...] IPv4 fdb groups functional -------------------------- [...] TEST: Replace FDB nexthop to non-FDB nexthop [ OK ] TEST: Replace non-FDB nexthop to FDB nexthop [ OK ] TEST: Replace FDB nexthop address while in a group [ OK ] TEST: Replace FDB nexthop to non-FDB nexthop while in a group [ OK ] TEST: Replace non-FDB nexthop to FDB nexthop while in a group [ OK ] [...] Tests passed: 40 Tests failed: 0 Tests skipped: 0 Signed-off-by: Ido Schimmel <[email protected]> Reviewed-by: David Ahern <[email protected]> Link: https://patch.msgid.link/[email protected] Signed-off-by: Jakub Kicinski <[email protected]>
