Fundamentally, any time a user operation changes the configuration of the networking, we must hold the RTNL. Eliding the RTNL for lookups is fine, but for things that change state it is not. I therefore think you'll need to rework the arp_ioctl() portions of the commit that introduced this regression. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
