pppd: Retain foreign default routes on Linux
|
|
|
|
On Linux, when pppd attempts to delete its default route it does not fill
|
|
the rt_dev field of the struct rtentry used to match the system default route.
|
|
As a consequence, pppd happily deletes any default route even if it belongs
|
|
to another interface.
|
|
|
|
This patch makes pppd fill out the rt_dev field so that only own default
|
|
routes are ever matched.
