pppd: Fill in default gateway on Linux
|
|
|
|
On Linux, when pppd creates the default route, it does not set the peer
|
|
address as gateway, leading to a default route without gateway address.
|
|
|
|
This behaviour breaks various downstream programs which attempt to infer
|
|
the default gateway IP address from the system default route entry.
|
|
|
|
This patch addresses the issue by filling in the peer address as gateway
|
|
when generating the default route entry.
