src: add log flags syntax support
Now NF_LOG_XXX is exposed to the userspace, we can set it explicitly. Like iptables LOG target, we can log TCP sequence numbers, TCP options, IP options, UID owning local socket and decode MAC header. Note the log flags are mutually exclusive with group. Some examples are listed below: # nft add rule t c log flags tcp sequence,options # nft add rule t c log flags ip options # nft add rule t c log flags skuid # nft add rule t c log flags ether # nft add rule t c log flags all # nft add rule t c log flags all group 1 <cmdline>:1:14-16: Error: flags and group are mutually exclusive add rule t c log flags all group 1 ^^^ Signed-off-by: Liping Zhang <> Signed-off-by: Pablo Neira Ayuso <>
