[Openswan dev] Bugreport: ipsec eroute fails / Addendum for http://bugs.xelerance.com/view.php?id=1018

[Carsten Schlote]

Hi,

unfortunately the Bugtracker account sign-on page is down, so I can't
create reports there. So just in short some error report related to
http://bugs.xelerance.com/view.php?id=1018. 

Problem: Same as described on tracker. No segfault, but a GLIBC
assertion on free(). mast0 and ipsec0 interfaces are available and the
isakmp phase worked successfully. Anyway, a problem with 'ipsec eroute
--clear' prevents completion of tunnel setup. If you ignore the error
and try to --up a connection something else is failing (see below).

I upgraded to openswan 2.6.20rc2+Harald Jennys NAT-T patch - no
difference.

If anyone knows more about this problem and can point to the right
places I might be able to trackdown and fix the problem. Any help
apreciated.

Otherwise an account on the bugtracker could help. Paul please fix your
tracker and GIT repo :-)

Carsten
