That is not going to work, especially if you have more than three or more ABIs in the system. Like, o32/n32/64 for mips (or i386/x86_64/x32). A report about that happens about every year on the mailing list. The only fix is to define a v4, and to make sure that there is no implicit padding of 32 bits or more. -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
