When enable print_memory_map() for debugging, the warning message
presents because of the types. Fix it by adding the macros in

grub_file_open() calls grub_file_get_device_name(), but doesn't check
the return. Instead, it checks if grub_errno is set.
However, nothing initialises grub_errno here when grub_file_open()
starts. This means that trying to open one file that doesn't exist and
then trying to open another file that
Since font files can be wrapped as PE images by grub-wrap, use shim to
verify font files if Secure Boot is enabled. To prevent other PE files

There is a problem in shim lock verifier after PE wrappers created by
grub-wrap are introduced. The shim lock verifier always says a file is
ok as long as shim says that file is ok, so there is a possibility that
wrappers may be used as kernel images, leading to crashes or
vulnerabilities.

This file filter can unwrap a file wrapped by grub-wrap. This process is
done automatically and transparently, thus no additional code is
required at user's side.
First, it checks for file type flags and ignore irrelevant files. Then,

Hi,
This patchset introduces a utility: grub-wrap. It can wrap a non-PE file
as a PE file, which can be subsequently digitally signed (and verified
by shim). The wrapped file will be unwrapped at runtime automatically
and transparently by the unwrap filter.
With grub-wrap, a PF2 font file can be
This new tool can wrap a non-PE file as a PE image, which can be

It's important that this type of PE images must be rejected when trying
to execute them. This is done by making them look like plain Windows
DLLs instead of UEFI images. Major dif

There is a problem in ascii_glyph_lookup(). It doesn't check the return
value of grub_malloc(). If memory can't be allocated, then NULL pointer
will be written to.
This patch fixes the problem by fallbacking to unknown_glyph in case of
grub_malloc() returns NULL.

If max_char_width or max_char_height is negative, bad values might be
propagated by grub_font_get_max_char_width() or
grub_font_get_max_char_height(). Prevent this from happening.

This patch adds an argument 'scale' to grub_font_draw_glyph(). If
scale > 1, then the function will create a new scaled bitmap of the
drawing glyph, and draws the scaled glyph. The scaled bitmap is cached
in the glyph itself, so it can be reused if same glyph is used many
times.

Hi,
PATCH 1-3 are additional fixes to font code.
PATCH 4-5 are the refactored and rebased version of HiDPI patches. They
add preliminary HiDPI support for gfxterm. There is no HiDPI support for
gfxmenu yet.
