Re: BUG: 2.6.25-rc1: iptables postrouting setup causes oops

Haavard,

It means your application is not capable(sic) of using the upper 32-bits
of the 64-bit capability sets supported by this newer kernel.

You might consider rebuilding the offending application linking it
against a newer version of libcap:

http://www.kernel.org/pub/linux/libs/security/linux-privs/libcap2/

However, it is a warning and, for any existing app that doesn't care
about newly added capabilities, the warning is benign.

Cheers

Andrew
