This is my first time posting, I am not sure if I'm in the right place, so correct me if I'm wrong. I recently compiled 2.4.20 with netfilter support, with the owner module (-m owner), and after several attempts of trying to use it (worked for 2.4.18), it gives an error. [root@scsi1 slinksi]# iptables -I OUTPUT -m owner --uid-owner root iptables: Target problem setsockopt(3, SOL_IP, 0x40 /* IP_??? */, [1953261926], 912) = -1 EINVAL (Invalid argument) (strace) This is enabled in the netfilter section, compiled in, not as a module, I also have grsecurity support (1.9.8) . Any help is appreciated, I am going to try 2.4.19.
