tty: remove file from tty_ldisc_ops::ioctl and compat_ioctl

2021-11-25T17:36:27+00:00

After the previous patches, noone needs 'file' parameter in neither
ioctl hook from tty_ldisc_ops. So remove 'file' from both of them.

tty: remove file from tty_mode_ioctl

2021-09-22T14:59:13+00:00

The only user of 'file' parameter in tty_mode_ioctl is a BUG_ON check.
Provided it never crashed for anyone, it's an overkill to pass the
parameter to tty_mode_ioctl only for this check.

If we wanted to check 'file' there, we should handle it in more graceful
way anyway. Not by a BUG == crash.

tty: make tty_ldisc_ops::hangup return void

2021-09-22T14:59:13+00:00

The documentation says that the return value of tty_ldisc_ops::hangup
hook is ignored. And it really is, so there is no point for its return
type to be int. Switch it to void and all the hooks too.

slip/plip: use ndo_siocdevprivate

2021-07-27T19:11:44+00:00

slip and plip both use a couple of SIOCDEVPRIVATE ioctl
commands that overload the ifreq layout in a way that is
incompatible with compat mode.

Convert to use ndo_siocdevprivate to allow passing the
data this way, but return an error in compat mode anyway
because the private structure is still incompatible.

This could be fixed as well to make compat work properly.

tty: no checking of tty_unregister_ldisc

2021-05-13T14:57:17+00:00

tty_unregister_ldisc now returns 0 = success. No need to check the
return value. In fact, the users only warned if an error occured and
didn't do anything useful anyway -- the ldisc module was unloaded in any
case.

tty: make tty_ldisc_ops a param in tty_unregister_ldisc

2021-05-13T14:57:16+00:00

Make tty_unregister_ldisc symmetric to tty_register_ldisc by accepting
struct tty_ldisc_ops as a parameter instead of ldisc number. This avoids
checking of the ldisc number bounds in tty_unregister_ldisc.
