pppd: Do not clobber exit codes on hangup
|
|
|
|
When a modem hangup occurs, pppd unconditionally sets the exit status code
|
|
to EXIT_HANGUP. This patch only sets EXIT_HANGUP if the exit status code is
|
|
not already set to an error value.
|
|
|
|
The motiviation of this patch is to allow applications which remote control
|
|
pppd to react properly on errors, e.g. only redial (relaunch pppd) if there
|
|
was a hangup, but not if the CHAP authentication failed.
