fbcon now prevents switching to screen resolutions which are smaller than the font size, and prevents enabling a font which is bigger than the current screen resolution. This fixes vmalloc-out-of-bounds accesses found by KASAN. Guiling Deng fixed a bug where the centered fbdev logo wasn't displayed correctly if the screen size matched the logo size. Hsin-Yi Wang provided a patch to include errno.h to fix build when CONFIG_OF isn't enabled. -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQS86RI+GtKfB8BJu973ErUQojoPXwUCYsfdCgAKCRD3ErUQojoP XxhvAP9HYH0XcfHGEIQ3YSyFRY4JpyLb0TcTD7mnrYwPgAw+KAD7Bw9EE7WhGZLC 7iuDn30/mdCFqiz3IuTjoRKYuG2ceg8= =yrqq -----END PGP SIGNATURE----- Merge tag 'for-5.19/fbdev-3' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/linux-fbdev Pull fbdev fixes from Helge Deller: - fbcon now prevents switching to screen resolutions which are smaller than the font size, and prevents enabling a font which is bigger than the current screen resolution.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
