Userspace `ipset` command forbids family option for hash:mac type: ipset create test hash:mac family inet4 ipset v6.30: Unknown argument: `family' However, this check is not done in kernel itself. When someone use external netlink applications (pyroute2 python library for example), one can create hash:mac with invalid family and inconsistant results from userspace (`ipset` command cannot read set content anymore). This patch enforce the logic in kernel, and forbids insertion of hash:mac with a family set. Since IP_SET_PROTO_UNDEF is defined only for hash:mac, this patch has no impact on other hash:* sets Signed-off-by: Florent Fourcot <[email protected]> Signed-off-by: Victorien Molle <[email protected]> Signed-off-by: Jozsef Kadlecsik <[email protected]>
