Subject: Default netfilter kernel buffer size?
Date: Thu, 12 Jun 2014 16:29:36 -0500 [thread overview]
Message-ID: <007501cf8685$69b9a460$3d2ced20$@gmail.com> (raw)
I have been searching around and can't find it so maybe someone can tell me.
I am looking for the default size of the kernel queue netfilter uses and if
there is a /proc file to see what the current setting is?
The story is I have a program that marks packets coming into netfilter.
On slower devices while a blacklist loads I have run into ENOBUFS error from
recv.
I am thinking that if I use nfq_set_queue_maxlen to set this to a higher
number I won't get the ENOBUFS error but I can't find the default to know
what may be a larger number.
Also I can't find any /proc file to show me the current number. Does one
exist and is it the same for 2.6.20+ kernels?
This is on a 3.14.6 kernel with netfiler 1.0.2 and nfnetlink 1.0.1
