Can you please try this preliminary patch and report back? You only need to rebuild kernel and reboot with the attached patch to enable use of e.g. 32-bit route(8) command on amd64 kernel. No any userland utility needs to rebuild to enable the compatibility. Tested on 8.2 amd64 only with route get default and route delete/add. --=20 wbr, pluknet --e89a8f646a1dac909804af491af9 Content-Type: text/x-patch; charset=US-ASCII; name="rtmsg32.diff"
