Hi there!
I've been testing nftables at sparc, looking for endianess issues.
Unfortunately, weird things happened.
Adding some rule:
% nft add table filter
% nft add chain filter input
% nft add rule filter input tcp dport 22 counter
% nft list table filter
table ip filter {
chain input {
payload @th,16,16 0x0 [invalid type] counter packets 0 bytes 0
}
}
However, matching happened when I generated some traffic.
Also, compiling the nft cli tool:
% make
