Obviously, if you try to use some new feature on older kernel, an error will result. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

iproute2 compatibility
Hi Stephen : I was looking around but could not find clear evidence that a later version of iproute2 is compatible with an older kernel. Specifically, we are wondering if iproute2 v 3.6 is compatible with linux kernel 3.4. Highly appreciate any pointers on this. thanks ani -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Re: [PATCH] [IPROUTE2] Compatibility with iptables 1.4.0
I just submitted a tested, slightly reduced patch (example we dont need to register matches) and it works as expected now. Thanks for the excellent work Denys. Pablo, below looks an oversight. I think there are some libraries like the mark target need also to be backward compatible. cheers, jamal On Mon, 2007-24-12 at 11:30 -0500, jamal wrote: > Grr.

[PATCH] [IPROUTE2] Compatibility with iptables 1.4.0
Hi, probably like this will be better?
Previous patch was not backward compatible.
Btw i checked twice, name is changed from libipt_MARK to libxt_MARK. So
probably when you have tested this, your iproute2 was looking to old
libipt_MARK (iptables is not deleting old libraries on make install).
-
New iptables 1.4.0 need additional dummy functions, and some library names is
changed from libipt to libxt.
It is prefferable also to open libxt_ first, as newer "style".
