With current versions of iptables there are suffixes (nf_tables) or (legacy) after the version string printed by iptables -V
The awk script does not remove those suffixes after the version string. ocf_version_cmp fails to compare this string. wait option will never be added if (nf_tables) or (legacy) is present after vX.Y.Z
In my lab ports listed in block/unblock primitives were never unblocked when a group was stated to be successfully started. DROP entries are accumulating with every restart.
With the corrected version detection this was fixed and worked as expected.
