Hi, While testing iptables-compat, I've come across some weird behavior: # iptables-compat -t mangle -N TEST # iptables-compat -t mangle -A PREROUTING -j TEST This works nicely, but when we put something in the TEST chain: # iptables-compat -t mangle -A TEST -j MARK --set-mark 0x80000000/0x80000000 # iptables-compat -t mangle -A PREROUTING -j TEST iptables-compat: Invalid argument. Run `dmesg' for more information. dmesg does not contain any information. The same problem exists for all default chains in mangle, filter and nat. Kernel is: 4.1-rc5 iptables: git://git.netfilter.org/iptables, branch master, commit 0bb1859e2d6dd79a0a59c3ee65f6a78cba118b86 nftables: git://git.netfilter.org/nftables, branch next-4.1, commit a93bc1795b272174a10d90961a248f2c620bfa2c Any ideas?
