** Description changed:
The /usr/share/vpnc-scripts/vpnc-script handles updates to the default
route using two different codepaths. In one codepath, the command "ip
route replace" is used to update the original default route with new
one (and to restore it later). The replace command in the update case
does not work if the original route default route has non-standard
attributes. For example, an original default route like this:
- $ sudo ip route
- default via 192.168.1.254 dev wlp3s0 proto static metric 600
- 169.254.0.0/16 dev wlp3s0 scope link metric 1000
- 192.168.1.0/24 dev wlp3s0 proto kernel scope link src 192.168.1.85 metric
600
+ $ sudo ip route
+ default via 192.168.1.254 dev wlp3s0 proto static metric 600
+ 169.254.0.0/16 dev wlp3s0 scope link metric 1000
+ 192.168.1.0/24 dev wlp3s0 proto kernel scope link src 192.168.1.85 metric
600
cannot be simply "ip route replace"d by a command of the form "ip route
replace dev <foo>". Also, the present logic to save and then restore the
original rute is broken because not all the route attributes are
preserved AND the replacement attributes don't match the attributes of
the new default route.
The attached patch addresses both these problems.

+ $ dpkg-query -l | egrep 'vpnc-scripts|iproute'
+ ii iproute 1:4.1.1-1ubuntu1 all transitional dummy package
for iproute2
+ ii iproute2 4.1.1-1ubuntu1 amd64 networking and traffic
