[B.A.T.M.A.N.] tcp filtering in batman-adv

[Krishnathiepan Rasanayagam]

Hi All,

Had anyone of you have ever done tcp filtering in batman - adv.
I have started to code it in send.c file in batman code. Using skb_buff
But not getting any expected out puts.
Any one have any better solutions?

Thanks in advance.

To avoid continuing this guessing game - would you mind explaining
a little what you want to achieve exactly in the end and why? I'm a
little curious :). And maybe that'll help finding the easiest,
most convinient way.

hi,

oh. No suspense :)
i am currently experimenting with QoS services which can be provided
by batman-adv, for that thinking about creating a queue inside send.c
with packet filtering. thats why i wanna know where to read the data.

best regards,

Hi Krishha

What can you do inside BATMAN which is not possible using TC on the
hard interfaces?

Hi Andrew,

i don't understand you, can you rephrase it?

This is the normal way to do QoS within Linux. You can do traffic
shaping, scheduling, policing, etc. I've not tried it, but you should
be able to apply tc commands to both the soft interface, bat0, and the
hard interface, wlan0.

Now you seem to be saying you want to do QoS in the middle of BATMAN.
Why? What can you do in the middle, which TC cannot do?

actually Andrew,
when i found that you can do port filtering in send.c i thought about
using that idea combining with kthreads to do QoS using batman-adv.
have you ever tried tc using batman-adv?
if so let me know how you did it
