wscons_callbacks.h

UTF-8 support for wsdisplay emulation modes. Both vt100 and sun emulation will now recognize xterm-compatible escape sequences ESC % G and ESC % @ to enter and leave UTF-8 mode, respectively.

Disable double width and height escape sequences under SMALL_KERNEL.

Implement support for framebuffers that don't start on a page boundary. This happens on the new 14" and 16" Macbook Pro where we deliberately use a framebuffer that skips the first few lines to avoid "the notch". The offset of the first pixel is added to struct wsdisplay_fbinfo. The stride is added as well, mirroring the value returned by the WSDISPLAYIO_LINEBYTES ioctl, such that we can retire that one in the future. A compat ioctl is implemented to help the transition. The compat code will be removed after OpenBSD 7.3 has been released.

Switch to console before suspending in DUMBFB mode. Fixes frame buffer corruption and a few other bugs/races after wakeup on Apple Silicon laptops and Lenovo x13s.

wsdisplay_compat_usl.c

The "USL" VT switch and keyboard ioctls are a hack and don't follow the proper BSD way where the third argument is always a pointer and data is transferred between userland and kernel using copyin(9) and copyout(9). Intead an int is encoded in the thirs argument. This works on 32-bit architectures and little-endian 64-bit architectures. But not on big-endian 64-bit architectures. Deal with this by handling the argument as long (which matches the size of a pointer).

Remove 'option COMPAT_PCVT' now that X doen't use it anymore. An X server built after april 3 is needed to be able to start X with the new kernel. ok kettenis@

wsemul_vt100_subr.c

Add a few missing bounds checks when processing terminal escape sequences. Without them, the kernel could be made to crash or reboot after receiving some specially crafted terminal escape sequences.

Prevent a double free by assigning the new keymap and corresponding size after the allocation and initialization is done. Otherwise, a race is possible if malloc ends up sleeping.

Currently, wskbd_set_mixervolume() only adjusts the volume of the first attached audio device, i.e. audio0. This approach does not work well while using additional audio devices equipped with physical volume keys since those would only affect the volume of audio0.

Serialize access to the list of attached child devices belonging to a wsmux. When invoking wsevsrc_* functions on a attached child device, underlying driver can sleep; this introduces a race where another thread is able to modify the list leading to all kinds of corruptions.
