How to handle mount requests that arrive during a shutdown is a big
|
|
|
304803 |
problem.
|
|
|
304803 |
|
|
|
304803 |
Currently common cases result in the requesting process being sent a
|
|
|
304803 |
fail status and success being returned to the calling autofs process.
|
|
|
304803 |
|
|
|
304803 |
There are a number of places where a fail is returned to the calling
|
|
|
304803 |
process (such as memeory allocation errors) which should cause the
|
|
|
304803 |
daemon to exit. But when a request arrives during a shutdown the
|
|
|
304803 |
daemon is usually not ready to shutdown and instead performs recovery
|
|
|
304803 |
and returns to a ready state instead of shutting down.
|
|
|
304803 |
|
|
|
304803 |
There were a few places in handle_packet_missing_direct() where a fail
|
|
|
304803 |
was being returned when a success should have been returned which was
|
|
|
304803 |
preventing the completion of the shutdown.
|
|
|
304803 |
|
|
|
304803 |
This is not ideal because during a restart of the daemon processes
|
|
|
304803 |
requesting a mount could receive a mount failure. But this has been
|
|
|
304803 |
the policy for while now and it's very difficult to do in a different
|
|
|
304803 |
way.
