>Description:
openvpn-2.2.1 built from pkgsrc contains code to find the
default gateway, but it fails on NetBSD-current, resulting in
log messages like this:
NOTE: unable to redirect default gateway -- Cannot read current
default gateway from system
>How-To-Repeat:
Build and install openvpn on NetBSD-current. Attempt to use it with a
configuration that includes constructs like this:
--redirect-gateway def1
--route 10.0.0.0 255.0.0.0 net_gateway
The system's default IPv4 gateway is needed by both the the
--redirect-gateway option, and the net_gateway keyword used with the
--route option.
>Fix:
Change the code in openvpn-2.2.1/route.c to use the correct API on
NetBSD.
There are several versions of the get_default_gateway() function
in route.c. The culprit seems to be the one guarded by
#elif defined(TARGET_OPENBSD) || defined(TARGET_NETBSD)
in line 1933 of route.c.
I haven't investigated in detail, but it's suspicious that openvpn uses
it's own struct definitions instead of including appropriate headers
from the system.
