speakup: replace utils' u_char with unsigned char

2022-11-26T08:27:45+00:00

commit 92ca969ff8815f3feef2645199bd39bf594e5eeb upstream. drivers/accessibility/speakup/utils.h will be used to compile host tool to generate metadata. "u_char" is a non-standard type, which is defined to "unsigned char" on glibc but not defined by some libc, e.g. musl. Let's replace "u_char" with "unsigned char" Signed-off-by: Đoàn Trần Công Danh Reviewed-by: Samuel Thibault Cc: stable Link: https://lore.kernel.org/r/b75743026aaee2d81efe3d7f2e8fa47f7d0b8ea7.1665736571.git.congdanhqx@gmail.com Signed-off-by: Greg Kroah-Hartman

speakup: fix a segfault caused by switching consoles

2022-11-26T08:27:45+00:00

commit 0fc801f8018000c8e64a275a20cb1da7c54e46df upstream. This patch fixes a segfault by adding a null check on synth in speakup_con_update(). The segfault can be reproduced as follows: - Login into a text console - Load speakup and speakup_soft modules - Remove speakup_soft - Switch to a graphics console This is caused by lack of a null check on `synth` in speakup_con_update(). Here's the sequence that causes the segfault: - When we remove the speakup_soft, synth_release() sets the synth to null. - After that, when we change the virtual console to graphics console, vt_notifier_call() is fired, which then calls speakup_con_update(). - Inside speakup_con_update() there's no null check on synth, so it calls synth_printf(). - Inside synth_printf(), synth_buffer_add() and synth_start(), both access synth, when it is null and causing a segfault. Therefore adding a null check on synth solves the issue.

Merge tag 'tty-6.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty

Pull tty / serial driver updates from Greg KH: "Here is the big set of tty and serial driver changes for 6.0-rc1. It was delayed from last week as I wanted to make sure the last commit here got some good testing in linux-next and elsewhere as it seemed to show up only late in testing for some reason. Nothing major here, just lots of cleanups from Jiri and Ilpo to make the tty core cleaner (Jiri) and the rs485 code simpler to use (Ilpo). Also included in here is the obligatory n_gsm updates from Daniel Starke and lots of tiny driver updates and minor fixes and tweaks for other smaller serial drivers.

speakup: Generate speakupmap.h automatically

2022-06-27T13:15:55+00:00

speakupmap.h was not actually intended to be source code, speakupmap.map is. This resurrects the makemapdata.c and genmap.c tools to generate speakupmap.h automatically from the input and speakup headers, and the speakupmap.map keyboard mapping source file.

tty/vt: consolemap: make parameters of inverse_translate() saner

2022-06-10T11:37:01+00:00

- int use_unicode -> bool: it's used as bool at some places already, so make it explicit. - int glyph -> u16: every caller passes a u16 in. So make it explicit too. And remove a negative check from inverse_translate() as it never could be negative.
