From the recent discussion on the sparclinux ml <http://marc.theaimsgroup.com/?t=107575522300004&r=1&w=2> (for others), bridge-utils needs 64 bit support to work. This currently isn't available, but should be sometime before the 2004.1 release. As the release of 2004.1 approaches we won't be addressing this (64 bit userland) just yet. I'm lowering the severity to "normal" for the time being. Thanks to Santiago (Santi) Leon for providing the following fix to me to enable bridging on the Sparc64 platform. I have tested it under Debian unstable, using Kernel 2.4.25, and bridge-utils-0.9.6.tar.gz. The fix is as follows: Download bridge-utils-0.9.6.tar.gz source from bridge.sourceforge.net, untar it, edit bridge-utils/libbridge/libbridge_devif.c and search for a line that has this: return ioctl(br_socket_fd, SIOCDEVPRIVATE + 3, &ifr); and replace it with this: return ioctl(br_socket_fd, SIOCDEVPRIVATE, &ifr); (basically just remove the +3)... run make and again and try: (After you rebuild the bridge utilities, these should work beautifully!) bridge-utils/brctl/brctl addbr br0 bridge-utils/brctl/brctl adddif br0 eth0 bridge-utils/brctl/brctl show Santi mentioned that the newer kernels don't make SIOCDEVPRIVATE+3 a 64-bit compatible ioctl and that's why it doesn't work on the Sparc64 architecture. He also mentioned that the same fix works for the PowerPC64 Architecture so it might help for other 64bit architecture platforms. Note also that this is not scheduled to be fixed in bridge-tuils-0.9.7, so for now this seems to be the best work around for 64bit platforms.
