RTSP netfilter patch for 2.4.18

RTSP netfilter patch for 2.4.18

[Yaron Presente]

Hi All,
Is anyone aware of a RTSP netfilter patch which is suitable for a 2.4.18 
kernel (I could only find a patch for 2.4.21).
If no such patch already exists, should there be any significant problem 
to adapt the 2.4.21 patch to 2.4.18?
Thanks,
Yaron

Does the patch apply cleanly?  If it does, it should work okay.

No, unfortunately it doesn't. I had a problem with the modifications in 
netfilter_ipv4/ip_conntrack.h .
The patch tries to insert exp_rtsp_info and ct_rtsp_info into the union 
ip_conntrack_expect_help,
which does not exist in my 2.4.18 source.
Looking at the ftp 2.4.18 patch as a reference, I see that a ct_ftp_info 
does exist, but in a different context in the header file.
an exp_ftp_info structure, however, is not defined at all.
Any ideas?

I will try to get a patch to you within a few days.  However, I will not be
able to test it except to verify that the kernel builds.  If you can use a
later kernel, that would be best.
