modification of sysdeps/unix/sysv/linux/check_pf.c in glibc 2.5 introduces a new "char pad[3]" in "struct req" and "assert (sizeof (req) - offsetof (struct req, pad) == 3)" several lines later. That assert fails on arm kernel (2.6.17 headers). As stated in the comment: /* struct rtgenmsg consists of a single byte. This means there are three bytes of padding included in the REQ definition. We make them explicit here. */ explicit bytes are not good thing to that code should be disabled to make glibc-2.5 work correctly on arm (lines 71, 68 and 69).
this is known upstream, i'm just waiting for what people are going to be doing about it
fixed in cvs with patch from upstream
