I can confirm this

Exactly the same here on nearly every ~amd64 pc (3 in a row).

Generic bug w/ glibc 2.8. Submitter, please add to #225459
Fix is to define _GNU_SOURCE, e.g. like in:
http://bugs.gentoo.org/attachment.cgi?id=156073 or others.

Patch for ebuild: include peercred patch

Created an attachment (id=170485) [edit]
Patch to fix peercred

Could someone please test these patches and give feedback? It builds and should
work but I can't test a live VPN right now.

Well, it _seems_ to build and work fine here (if that's enough feedback).
If there were some test beyond my normal vpn stuff, please tell me ;)

Same here, rebuild, restart and all works as usually.
Thanks for patch.

Ditto on - patched ebuild compiles, and typical openvpn session works as
expected.

Thanks!

Patched confirmed ~x86.  It applies, builds and runs as expected.

Fix in cvs
Thanks
