[opensuse-factory] something seems not quite right with ping6
a) Factory, 64bit, looks good: per@airbus:~> ping6 www.clcommunications.ch PING www.clcommunications.ch(2001:8e0:2010:1fd::1:e049) 56 data bytes b) same system, not good: per@airbus:~> ping6 clcommunications.ch PING clcommunications.ch(5f8f:3cfa:2001:8e0:2010:1fd::) 56 data bytes
From 2a00:c38::1:0:f1 icmp_seq=1 Destination unreachable: No route From 2a00:c38::1:0:f1 icmp_seq=2 Destination unreachable: No route
where does this address "5f8f:3cfa:2001:8e0:2010:1fd::" come from? https://bugzilla.novell.com/show_bug.cgi?id=876521 -- Per Jessen, Zürich (21.4°C) http://www.hostsuisse.com/ - dedicated server rental in Switzerland. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Looks like shifted by 32 bits... If I had to guess, I would suspect it's the 32 bits by which offset of the address differs between struct sockaddr_in6 and struct sockaddr_in. If you can reproduce it, it would be good to know whether it is returned by resolver or whether it is mangled inside ping6.

Hi Michal it's easily reproduced, but I think it's already been fixed, check out the bugreport. /Per -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

It is a bug in glibc, it has been fixed by now. https://sourceware.org/git/?p=glibc.git;a=commit;h=8dc9751764eb1bedf06d19695... -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
