| 1 | pppd: Do not clobber exit codes on hangup |
| 2 | |
| 3 | When a modem hangup occurs, pppd unconditionally sets the exit status code |
| 4 | to EXIT_HANGUP. This patch only sets EXIT_HANGUP if the exit status code is |
| 5 | not already set to an error value. |
| 6 | |
| 7 | The motiviation of this patch is to allow applications which remote control |
| 8 | pppd to react properly on errors, e.g. only redial (relaunch pppd) if there |
| 9 | was a hangup, but not if the CHAP authentication failed. |
