Summary 0000940: iproute2 'OVERRUN: Bad address' on x86_64
Description Binaries from iproute2 from buildroot doesn't work on x86_64. It gives 'OVERRUN: Bad address' message. NETLINK is set in linux kernel, but it seems, the problem is in communication [see strace output].

On irc someboyd [mnemoc] has got the same issue. He had different gcc [gcc-4.1.1]. He has x86_64 as well. As he reported, on another architecture [I guess i686] the problem disappears with the same environment. He tried uclibc-0.9.28 as well without success. As he reported, with diet libc it works well with same version of kernel, iproute2 and compilation conditions.

I also tried iproute2-2.6.16-060323 but didn't help. As we the traces shows, the problem might be with uClibc.
Additional Information Host system: Ubuntu 6.0.6, 2.6.16.9, AMD64, gcc-4.0.3
Target system: buildroot r15663, x86_64, linux-2.6.17.4
Toolchain: uClibc-snapshot, gcc-3.4.6

 i have the same problem with iproute2's ip and BB's ip (1.1.3 and 1.2.0) against uclibc 0.9.28 and uclibc snapshot (random days during the last two weeks).
gcc 4.1.1, using T2 (http://www.t2-project.org/) [^] instead of buildroot.

i'm attaching the syscall traces of uclibc/iproute2 and then dietlibc/iproute2, both static with the same versions of everything (gcc=4.1.1). this issue happens on x86_64 and not on athlon xp or p4. no idea about other 64bits architectures.

 What is interesting, e.g. 'ip link set eth0 mtu 1200' and 'ip rule' works partially:
# ip rule
0: from all lookup local
32766: from all lookup main
32767: from all lookup default
OVERRUN: Bad address
