25850cfd50 Don't allow insmod when secure boot is enabled.
Hi,

Fedora's patch to forbid insmod in UEFI Secure Boot environments is fine
as far as it goes.  However, the insmod command is not the only way that
modules can be loaded.  In particular, the 'normal' command, which
implements the usual GRUB menu and the fully-featured command prompt,
will implicitly load commands not currently loaded into memory.  This
permits trivial Secure Boot violations by writing commands implementing
whatever you want to do and pointing $prefix at the malicious code.

I'm currently test-building this patch (replacing your current
grub-2.00-no-insmod-on-sb.patch), but this should be more correct.  It
moves the check into grub_dl_load_file.

004a2b1efd efi: check *path non-null before grub_strrchr
The EFI version of grub_machine_get_bootlocation crops the boot image
name back to the last / in order to get a directory path. However, it
does not check that *name is actually set before calling grub_strrchr
to do this, and neither does grub_strrchr before dereferencing a NULL
pointer.

Parent function, grub_set_prefix_and_root, does check the pointer
before using.

2a5a532c00 Support grub-emu on x32 (ILP32 but with x86-64 instruction set)
* configure.ac: Remove -m64 from checks for -mcmodel=large and
-mno-red-zone.  These are always either unnecessary (x86_64-emu) or
already in TARGET_CFLAGS at this point, and they produce incorrect
results when building for x32.
* grub-core/kern/x86_64/dl.c (grub_arch_dl_relocate_symbols): Cast
pointers to Elf64_Xword via grub_addr_t, in order to work on x32.
* include/grub/x86_64/types.h (GRUB_TARGET_SIZEOF_VOID_P,
GRUB_TARGET_SIZEOF_LONG): Define to 4 on x32.

GRUB_IEEE1275_FLAG_HAS_CURSORONOFF. This resulted in cursor not being
