Yes I know that, obviously:) The point here is that nfnl_rcvbufsiz() has been advertised in the main page of libnetfilter_queue HTML for a long time and there are likely a number of systems out there that use it. When libnfnetlink is removed, libnetfilter_queue will have to provide nfnl_rcvbufsiz() or those systems will start failing. I have in mind that although libnetfilter_queue will provide nfnl_rcvbufsiz(), there will be no documentation for it. You will see in https://patchwork.ozlabs.org/project/netfilter-devel/patch/20231112065922.3414-2-duncan_roe@xxxxxxxxxxxxxxx/ I replaced the advice to use nfnl_rcvbufsiz() (in 2 places) with advice to use setsocketopt(). I only mentioned that programs calling nfnl_rcvbufsiz() will continue to run. So I offered this patch as the only documentation of how to use nfnl_rcvbufsiz(). I need it for my testing, but it's fine with me if you don't want to take it. Cheers ... Duncan.
