Actually, what Ed (and me too) was wondering about was: why does `ip route show table $[0x80000000]` not print an empty table, i.e. where is it that some code uses int/s32 during parsing of the argument and/or the RTA_TABLE attribute? -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
