Subject: Don't try to shutdown() a pty
|
|
|
|
shutdown() of a pty doesn't work (ENOTSOCK), so we should close
|
|
it instead.
|
|
|
|
This will ensure that PTY controlling terminals are closed when a
|
|
session exits, including when multiple sessions run over a single SSH
|
|
connection. In the normal case of a single session, the PTY controlling
|
|
terminal would be closed when the Dropbear server process exits anyway.
|
|
|
|
This possibly fixes #264 on github
|
|
|
|
It is possible that there could be subtle changes to PTY flushing
|
|
behaviour, though nothing caught by tests at present.
