vt: push down tioclinux cases

2012-03-08T19:10:27+00:00

Some of this ventures into selection which is still a complete lost cause. We
are not making it any worse. It's completely busted anyway.

vt: push down the tty lock so we can see what is left to tackle

2012-03-08T19:10:27+00:00

At this point we have the tty_lock guarding a couple of oddities, plus the
translation and unimap still.

We also extend the console_lock in a couple of spots where coverage is wrong
and switch vcs_open to use the right lock !

[Fixed the locking issue Jiri reported]

vt:tackle kbd_table

2012-03-08T18:50:35+00:00

Keyboard struct lifetime is easy, but the locking is not and is completely
ignored by the existing code. Tackle this one head on

- Make the kbd_table private so we can run down all direct users
- Hoick the relevant ioctl handlers into the keyboard layer
- Lock them with the keyboard lock so they don't change mid keypress
- Add helpers for things like console stop/start so we isolate the poking
  around properly
- Tweak the braille console so it still builds

There are a couple of FIXME locking cases left for ioctls that are so hideous
they should be addressed in a later patch. After this patch the kbd_table is
private and all the keyboard jiggery pokery is in one place.

This update fixes speakup and also a memory leak in the original.

vt: lock the accent table

2012-02-24T21:59:34+00:00

First step to debletcherising the vt console layer - pick a victim and fix
the locking

This is a nice simple object with its own rules so lets pick it out for
treatment. The user of the table already has a lock so we will also use the
same lock for updates.

drivers/tty/vt/vt_ioctl.c: fix KDFONTOP 32bit compatibility layer

2012-02-04T00:16:41+00:00

KDFONTOP(GET) currently fails with EIO when being run in a 32bit userland
with a 64bit kernel if the font width is not 8.

This is because of the setting of the KD_FONT_FLAG_OLD flag, which makes
con_font_get return EIO in such case.

This flag should *not* be set for KDFONTOP, since it's actually the whole
point of this flag (see comment in con_font_set for instance).

vt: Add K_OFF return value to vt_ioctl KDGKBMODE

After adding support for K_OFF in KDSKBMODE, it was forgotten to
add support for returning it in KDGKBMODE.
