vt: fix \e[2m using the wrong placeholder color on graphical consoles

2017-06-09T09:20:08+00:00

Only vgacon and sisusbcon did it right, the rest (via generic code) tried underline (usually cyan). Signed-off-by: Adam Borowski Signed-off-by: Greg Kroah-Hartman

Merge branch 'vt_copy_cleanup' into tty-next

2017-06-09T09:19:02+00:00

The vt copy_from/to_user cleanups were in a separate branch for others to work off of. Signed-off-by: Greg Kroah-Hartman

vt: drop access_ok() calls in unimap ioctls

2017-06-09T09:07:36+00:00

Done by copy_{from,to}_user(). Signed-off-by: Adam Borowski Signed-off-by: Greg Kroah-Hartman

vt: use memdup_user in PIO_UNIMAP ioctl

2017-06-09T09:07:36+00:00

Again, a nice linear transfer that simplifies the code. Signed-off-by: Adam Borowski Signed-off-by: Greg Kroah-Hartman

vt: use copy_to_user instead of __put_user in GIO_UNIMAP ioctl

2017-06-09T09:07:36+00:00

A nice big linear transfer, no need to flip stac/PAN/etc every half-entry. Also, yay __put_user() after checking only read. Signed-off-by: Adam Borowski Signed-off-by: Greg Kroah-Hartman

vt: fix unchecked __put_user() in tioclinux ioctls

2017-06-09T09:07:36+00:00

Only read access is checked before this call. Actually, at the moment this is not an issue, as every in-tree arch does the same manual checks for VERIFY_READ vs VERIFY_WRITE, relying on the MMU to tell them apart, but this wasn't the case in the past and may happen again on some odd arch in the future. If anyone cares about 3.7 and earlier, this is a security hole (untested) on real 80386 CPUs. Signed-off-by: Adam Borowski CC: stable@vger.kernel.org # v3.7- Signed-off-by: Greg Kroah-Hartman

vt: use copy_from/to_user instead of __get/put_user for scrnmap ioctls

2017-06-09T09:07:36+00:00

Linus wants to get rid of these functions, and these uses are especially egregious: they copy a big linear array element by element. Signed-off-by: Adam Borowski Signed-off-by: Greg Kroah-Hartman

tty/vt/keyboard: Remove AVR32 bits from the driver

2017-05-18T14:34:55+00:00

AVR32 is gone. Now it's time to clean up the driver by removing leftovers that was used by AVR32 related code. Signed-off-by: Andy Shevchenko Signed-off-by: Greg Kroah-Hartman

vt: make mouse selection of non-ASCII consistent

2017-04-11T19:39:15+00:00

For some reason a handful of ISO-8859-1 symbols are excluded from "word chars" while the vast majority of Unicode is hard-coded as included, even when inappropriate (we really would want to _not_ select line-drawing/etc). Those symbols are: ¡¢£¤¥¦§¨©ª«¬®¯°±²³´µ¶·¸¹º»¼½¾¿×÷ Thus, let's not special-case any non-ASCII anymore. Attempts to set these via ioctl will be silently ignored. As an extra bonus, we debloat the kernel by 128 bytes. Signed-off-by: Adam Borowski Signed-off-by: Greg Kroah-Hartman

vt: set mouse selection word-chars to gpm's default

2017-04-11T19:39:14+00:00

Since forever, gpm was this code's only user, and it overrides the table on start so the default was never seen -- until Bill Allombert's "consolation" came in. The in-kernel set is "A-Za-z0-9_" which fails to catch typical file names, etc. Let's change this to gpm's conservative default, ie "-A-Za-z0-9_./"; most terminals include more, for example xfce4-terminal has "-A-Za-z0-9,./?%&#:_=+@~".
