named[]: IPv6 structures in kernel and user space do not match.

[Stephen Bowyer]

Hi.

I am having trouble getting IPv6 in BIND (9.2.3) working. After trawling
though the internet I think the problem may be with my glibc. I have glibc
2.3.2 and Linux kernel 2.4.23-pre9.

I compiled and ran some code suggested by Sjoerd that I found at
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=82468 and it seems my
sockaddr_in6 returns 24 bytes while I think it should be 28.

I'm searching for any advice. Is this a problem with glibc? Or am I
looking in the wrong place?


$ ./a.out
getpeername len -> 28, sizeof(sockaddr_in6) -> 24

$ ldd ./a.out
        libc.so.6 => /usr/local/glibc2.3.2/lib/libc.so.6 (0x4002a000)
        /usr/local/glibc2.3.2/lib/ld-linux.so.2 =>
/usr/local/glibc2.3.2/lib/ld-linux.so.2 (0x40000000)
