Hello plaisthos, flichtenheld,
I'd like you to do a code review.
Please visit
http://gerrit.openvpn.net/c/openvpn/+/528?usp=email
to review the following change.
Change subject: Route: remove incorrect routes on exit
......................................................................
Route: remove incorrect routes on exit
Implemented a safeguard to verify the returned value
from add_route3() when the default gateway is not a local
remote host.
Prior to this implementation, RT_DID_LOCAL flag was
erroneously set even in case of add_route3() failure.
This problem typically occurs when there's no default
route and the --redirect-gateway def1 option is specified,
and in case of reconnection makes it impossible for the client
to reobtain the route to the server.
This fix ensures OpenVPN accurately deletes the appropriate
route on exit by properly handling add_route3() return value.
Fixes: Trac #1457
