Hello,

Started working with netfilter under Selinux and I noted that it was
grouped with ipchains and labeled as 
/sbin/iptables                  system_u:object_r:ipchains_exec_t

Should this have a separate label and it's own te file?

Only if it requires a distinct set of permissions and you want to enforce
that distinction in the policy.

Hi there

I wonder if I could ask you one question please about
netfilter? I wonder if it can be used to prioritise
traffic, by that I mean when two packets are sent to
the same destination, one can be delayed to let the
other packet pass first. if it can, can you tell me
what topic should I look for to get how to do that
please?

Yours sincerely

Sokhan H

I do not believe that is a netfilter function.  You could take a look at
iproute2.  The documentation is frequently found in a file named
ip-cref.ps

This is not the job of netfilter, but is instead done by the 
shaping/queueing components in the Linux kernel. See the tc command and 
related documentation.

"plz" consider the source, see the libiptc directory inside iptables.

I assume you are looking for sponsers for 2015 since July 2014 has
already passed... :-)

Hi ,

    We are looking at trying to retrieve the complete conntrack table
using libnetfilter_conntrack API's. But when we used the below
sequence of API's we see that the call back register is getting called
once for every entery in the conntrack table. The sequence of API's we
have used is as follows :



cb
..........
..........
    nfct_snprintf ();<=====returns one entry from conntrack table
..........
..........


main

        nfct_callback_register ( ); <===== NFCT_T_ALL to fetch all the enteries
        ret = nfct_query ();
........
........



Is there a away for me to get the whole conntrack table in a single
invocation of single callback function ? So that the cb function not
called multiple times?


Thanks and Regards,
