|

|
||||
Commit 68a0db1d7da2 reworked the baud rate selection, but also added
|
||||
a (not so) subtle change in the way the local flags (c_lflag in the
|
||||
termios structure) are handled, forcing the new flags to always be the
|
||||
same as the old ones.
|
||||
|
||||
The reason for that particular change is both obscure and undocumented.
|
||||
It also completely breaks userspace. Something as trivial as getty is
|
||||
unusable:
|
||||
|
||||
<example>
|
||||
Debian GNU/Linux 9 sy-borg ttyMV0
|
||||
|
||||
sy-borg login: root
|
||||
root
|
||||
[timeout]
|
||||
|
||||
Debian GNU/Linux 9 sy-borg ttyMV0
|
||||
</example>
|
||||
|
||||
which is quite obvious in retrospect: getty cannot get in control of
|
||||
the echo mode, is stuck in canonical mode, and times out without ever
|
||||
seeing anything valid. It also begs the question of how this change was
|
||||
ever tested.
|
||||
|
||||
The fix is pretty obvious: stop messing with c_lflag, and the world
|
||||
will be a happier place.

||||

tty_unregister_driver may be called more than 1 time in some

dbc_tty_driver to make sure it is unregistered only 1 time.
