Add translation for module cpu to nftables. Examples: $ sudo iptables-translate -A INPUT -p tcp --dport 80 -m cpu --cpu 0 -j ACCEPT nft add rule ip filter INPUT tcp dport 80 cpu 0 counter accept $ sudo iptables-translate -A INPUT -p tcp --dport 80 -m cpu ! --cpu 1 -j ACCEPT nft add rule ip filter INPUT tcp dport 80 cpu != 1 counter accept Signed-off-by: Shivani Bhardwaj <shivanib134@gmail.com> --- extensions/libxt_cpu.c | 13 ++++++++++++- 1 file changed, 12 insertions(+), 1 deletion(-)
