Hello Benoit,

The current patch should compile just fine with 3.8. I tested compilation with a 3.8rc kernel.

rtsp nat helper doesn't work on Linux 3.10. It compiles ok, when modprobed in dmesg you see:"nf_conntrack: automatic helper assignment is deprecated and it will be removed soon. Use the iptables CT target to attach helpers instead"
nat helping doesn't seem to work, same setup works ok with 3.7

Hi,

I also have issues with 3.10 ..
It starts to work but fails in the help_out function and stops.

Any idea ?

Did you try the new version I posted some time ago?
It still has the same name but apparently has some fixes.

Mike says:
Yep v2 and vanilla 3.7 are the same it is just a link.
As for the error you get. Was this working with earlier kernel versions?
My problem is that since I no longer have a linux router at home I can only compile test it.

TheTroll says:
Well it's the first time I try it and I am on 3.10...

But Panagiotis Malakoudis seems to have the same issue and it worked for him on the 3.7

Mike says:
Could you go back to 3.7 and try it with the same server?

Wed Mar 19 14:43:56 2014
TheTroll says:
If I could avoid, would be nice :)
It's not a server I want to reboot ...

TheTroll says:
Ok I tested on 3.7.10 and I have the same issue :/

Mike says:
Well while it does not necessarily mean that the server is broken the end result is the same.

Do you filter outgoing traffic in any way?

Well my OUTPUT filter chain is empty ...

TheTroll says:
I am doing some debugging and it seems that : get_skb_tcpdata

does not return a pointer to the actual protocol string..
So I try to retrieve the pointer using skb_header_pointer...

Will let you know

The following patch fixed it for me, but I got a kernel warning sometimes on the malloc part...

A version with a little bit less of mallocs :) I did not do the locks though...
