Subject: Documentation question (verdicts)
Date: Mon, 2 Dec 2019 21:26:23 +1100	[thread overview]
Message-ID: <20191202102623.GA775@dimstar.local.net> (raw)

Hi Pablo,

Queue handling [DEPRECATED] in libnetfilter_queue.c documents these 3:

> 278  *   - NF_ACCEPT the packet passes, continue iterations
> 281  *   - NF_REPEAT iterate the same cycle once more
> 282  *   - NF_STOP accept, but don't continue iterations

In my tests, NF_REPEAT works as documented - the input hook presents the packet
a second time. But, contrary to the above, the packet does not show again
after NF_ACCEPT.

Is that expected behaviour nowadays?

And if so, does that make NF_STOP redundant?

BTW if you'd like to try it, my test program nfq6 is a subdirectory at
https://github.com/duncan-roe/nfq (nfq itself is an ad blocker).

Cheers ... Duncan.
