Debian 11 package repositories. These packages can be found by searching
https://packages.debian.org/.
The Requirements
================

you don't have any of them, please obtain and install them before
configuring the GRUB.
* GCC 5.1.0 or later
Experimental support for clang 8.0.0 or later (results in much bigger binaries)
* GCC 4.1.3 or later
Note: older versions may work but support is limited
Experimental support for clang 3.3 or later (results in much bigger binaries)
for i386, x86_64, arm (including thumb), arm64, mips(el), powerpc, sparc64
Note: clang 3.2 or later works for i386 and x86_64 targets but results in
much bigger binaries.

Note: clang on arm64 is not supported due to
https://llvm.org/bugs/show_bug.cgi?id=26030
Note: clang 3.3 or later works for mips(el)
earlier versions fail to generate .reginfo and hence gprel relocations
fail.

earlier versions not tested
Note: clang 3.5 or later works for sparc64
earlier versions return "error: unable to interface with target machine"
Note: clang has no support for ia64 and hence you can't compile GRUB
for ia64 with clang

* GNU binutils 2.9.1.0.23 or later
* Flex 2.5.35 or later

* Other standard GNU/Unix tools
* a libc with large file support (e.g. glibc 2.1 or later)
@ -36,74 +49,24 @@ For optional grub-emu features, you need:
* SDL (recommended)
* libpciaccess (optional)
* libusb (optional)
To build GRUB's graphical terminal (gfxterm), you need:
* FreeType 2.1.5 or later
* GNU Unifont
To build grub-mkfont the unicode fonts are required (xfonts-unifont package
on Debian).
If you use a development snapshot or want to hack on GRUB you may
need the following.
* Python 3 (NOTE: python 2.6 should still work, but it's not tested)
* Autoconf 2.64 or later
* Automake 1.14 or later
Your distro may package cross-compiling toolchains such as the following
incomplete list on Debian: gcc-aarch64-linux-gnu, gcc-arm-linux-gnueabihf,
gcc-mips-linux-gnu, gcc-mipsel-linux-gnu, gcc-powerpc64-linux-gnu,
gcc-riscv64-linux-gnu, gcc-sparc64-linux-gnu, mingw-w64 and mingw-w64-tools.
More cross compiling toolchains can be found at the following trusted sites:
* https://mirrors.kernel.org/pub/tools/crosstool/
* https://toolchains.bootlin.com/
* Python 2.6 or later
* Autoconf 2.63 or later
* Automake 1.11 or later
Prerequisites for make-check:
* qemu, specifically the binary "qemu-system-ARCH" where ARCH is the
architecture GRUB has been built for; the "qemu-system" package on Debian
will install all needed qemu architectures
* OVMF, for EFI platforms (packages ovmf, ovmf-ia32, qemu-efi-arm, and
qemu-efi-aarch64)
* OpenBIOS, for ieee1275 platforms (packages openbios-ppc and openbios-sparc)
* qemu, specifically the binary 'qemu-system-i386'
* xorriso 1.2.9 or later, for grub-mkrescue and grub-shell
* wamerican, for grub-fs-tester
* mtools, FAT tools for EFI platforms
* xfonts-unifont, for the functional tests
* swtpm-tools and tpm2-tools, for TPM2 key protector tests
* If running a Linux kernel the following modules must be loaded:
- fuse, loop
- btrfs, erofs, ext4, f2fs, fat, hfs, hfsplus, jfs, mac-roman, minix, nilfs2,
reiserfs, udf, xfs
- On newer kernels, the exfat kernel modules may be used instead of the
exfat FUSE filesystem
* The following are Debian named packages required mostly for the full
suite of filesystem testing (but some are needed by other tests as well):
- btrfs-progs, dosfstools, e2fsprogs, erofs-utils, exfatprogs, exfat-fuse,
f2fs-tools, genromfs, hfsprogs, jfsutils, nilfs-tools, ntfs-3g,
reiserfsprogs, squashfs-tools, reiserfsprogs, udftools, xfsprogs, zfs-fuse
- exfat-fuse, if not using the exfat kernel module
- gzip, lzop, xz-utils
- attr, cpio, g++, gawk, parted, recode, tar, util-linux
Note that `make check' will run and many tests may complete successfully
with only a subset of these prerequisites. However, some tests may be
skipped or fail due to missing prerequisites.
To build the documentation you'll need:
* texinfo, for the info and html documentation
* texlive, for building the dvi and pdf documentation (optional)
To use the gdb_grub GDB script you'll need:
* readelf (binutils package)
* objdump (binutils package)
* GNU Debugger > 7, built with python support (gdb package)
* Python >= 3.5 (python3 package)

Note, that the autoconf 2.65 manual states that when using the --host argument
to configure, the --build argument should be specified as well. Not sending
--build, enters a compatibility mode that will be removed in the future.
Normally, for building a GRUB on amd64 with tools to run on amd64 to
generate images to run on ARM, using your Linux distribution's
packaged cross compiler, the following would suffice:
./configure --target=arm-linux-gnueabihf --with-platform=efi

Security Policy
===============
To report a vulnerability see "Reporting a Vulnerability" below.
Security Incident Policy
========================
Security bug reports are treated with special attention and are handled
differently from normal bugs. In particular, security sensitive bugs are not
handled in public but in private. Information about the bug and access to it
is restricted to people in the security group, the individual engineers that
work on fixing it, and any other person who needs to be involved for organisational
reasons. The process is handled by the security team, which decides on the people
involved in order to fix the issue. It is also guaranteed that the person reporting
the issue has visibility into the process of fixing it. Any security issue gets
prioritized according to its security rating. The issue is opened up to the public
in coordination with the release schedule and the reporter.
Disclosure Policy
=================
Everyone involved in the handling of a security issue - including the reporter -
is required to adhere to the following policy. Any information related to
a security issue must be treated as confidential and only shared with trusted
partners if necessary, for example to coordinate a release or manage exposure
of clients to the issue. No information must be disclosed to the public before
the embargo ends. The embargo time is agreed upon by all involved parties. It
should be as short as possible without putting any users at risk.
Supported Versions
==================
Only the most recent version of the GRUB is supported.
Reporting a Vulnerability
=========================
The security report should be encrypted with the PGP keys and sent to ALL email
addresses listed below. Every vulnerability report will be assessed within
72 hours of receiving it. If the outcome of the assessment is that the report
describes a security issue, the report will be transferred into an issue on the
internal vulnerability project for further processing. The reporter is updated
on each step of the process.
While there's currently no bug bounty program we appreciate every report.

@chapter Setting up and running test suite
GRUB is basically a tiny operating system with read support for many file
systems and which has been ported to a variety of architectures. As such, its
test suite has quite a few dependencies required to fully run the suite.
These dependencies are currently documented in the
@uref{https://git.savannah.gnu.org/cgit/grub.git/tree/INSTALL, INSTALL}
file in the source repository. Once installed, the test suite can be started
by running the @command{make check} command from the GRUB build directory.

@node Debugging
@chapter Debugging
GRUB2 can be difficult to debug because it runs on the bare-metal and thus
does not have the debugging facilities normally provided by an operating
system. This chapter aims to provide useful information on some ways to
debug GRUB2 for some architectures. It by no means intends to be exhaustive.
The focus will be one x86_64 and i386 architectures. Luckily for some issues
virtual machines have made the ability to debug GRUB2 much easier, and this
chapter will focus debugging via the QEMU virtual machine. We will not be
going over debugging of the userland tools (eg. grub-install), there are
many tutorials on debugging programs in userland.
You will need GDB and the QEMU binaries for your system, on Debian these
can be installed with the @samp{gdb} and @samp{qemu-system-x86} packages.
Also it is assumed that you have already successfully compiled GRUB2 from
source for the target specified in the section below and have some
familiarity with GDB. When GRUB2 is built it will create many different
binaries. The ones of concern will be in the @file{grub-core}
directory of the GRUB2 build dir. To aide in debugging we will want the
debugging symbols generated during the build because these symbols are not
kept in the binaries which get installed to the boot location. The build
process outputs two sets of binaries, one without symbols which gets executed
at boot, and another set of ELF images with debugging symbols. The built
images with debugging symbols will have a @file{.image} suffix, and the ones
without a @file{.img} suffix. Similarly, loadable modules with debugging
symbols will have a @file{.module} suffix, and ones without a @file{.mod}
suffix. In the case of the kernel the binary with symbols is named
@file{kernel.exec}.
In the following sections, information will be provided on debugging on
various targets using @command{gdb} and the @samp{gdb_grub} GDB script.
@menu
* i386-pc::
* x86_64-efi::
@end menu
@node i386-pc
@section i386-pc
The i386-pc target is a good place to start when first debugging GRUB2
because in some respects it's easier than EFI platforms. The reason being
that the initial load address is always known in advance. To start
debugging GRUB2 first QEMU must be started in GDB stub mode. The following
command is a simple illustration:
@example
qemu-system-i386 -drive file=disk.img,format=raw \
-device virtio-scsi-pci,id=scsi0 -S -s
@end example
This will start a QEMU instance booting from @file{disk.img}. It will pause
at start waiting for a GDB instance to attach to it. You should change
@file{disk.img} to something more appropriate. A block device can be used,
but you may need to run QEMU as a privileged user.
To connect to this QEMU instance with GDB, the @code{target remote} GDB
command must be used. We also need to load a binary image, preferably with
symbols. This can be done using the GDB command @code{file kernel.exec}, if
GDB is started from the @file{grub-core} directory in the GRUB2 build
directory. GRUB2 developers have made this more simple by including a GDB
script which does much of the setup. This file is at @file{grub-core/gdb_grub}
in the build directory and is also installed via @command{make install}.
When using a pre-built GRUB, the distribution may have a package which installs
this GDB script along with debug symbol binaries, such as Debian's
@samp{grub-pc-dbg} package. The GDB script is intended to be used
like so, assuming that @samp{/path/to/script} is the path to the directory
containing the gdb_grub script and debug symbol files:
@example
cd $(dirname /path/to/script/gdb_grub)
gdb -x gdb_grub
@end example
Once GDB has been started with the @file{gdb_grub} script it will
automatically connect to the QEMU instance. You can then do things you
normally would in GDB like set a break point on @var{grub_main}.
Setting breakpoints in modules is trickier since they haven't been loaded
yet and are loaded at addresses determined at runtime. The module could be
loaded to different addresses in different QEMU instances. The debug symbols
in the modules @file{.module} binary, thus are always wrong, and GDB needs
to be told where to load the symbols to. But this must happen at runtime
after GRUB2 has determined where the module will get loaded. Luckily the
@file{gdb_grub} script takes care of this with the @command{runtime_load_module}
command, which configures GDB to watch for GRUB2 module loading and when
it does add the module symbols with the appropriate offset.
@node x86_64-efi
@section x86_64-efi
Using GDB to debug GRUB2 for the x86_64-efi target has some similarities with
the i386-pc target. Please read and familiarize yourself with the @ref{i386-pc}
section when reading this one. Extra care must be used to run QEMU such that it
boots a UEFI firmware. This usually involves either using the @samp{-bios}
option with a UEFI firmware blob (eg. @file{OVMF.fd}) or loading the firmware
via pflash. This document will not go further into how to do this as there are
ample resource on the web.
Like all EFI implementations, on x86_64-efi the (U)EFI firmware that loads
the GRUB2 EFI application determines at runtime where the application will
be loaded. This means that we do not know where to tell GDB to load the
symbols for the GRUB2 core until the (U)EFI firmware determines it. There are
two good ways of figuring this out when running in QEMU: use a @ref{OVMF debug log,
debug build of OVMF} and check the debug log, or have GRUB2 say where it is
loaded. Neither of these are ideal because they both generally give the
information after GRUB2 is already running, which makes debugging early boot
infeasible. Technically, the first method does give the load address before
GRUB2 is run, but without debugging the EFI firmware with symbols, the author
currently does not know how to cause the OVMF firmware to pause at that point
to use the load address before GRUB2 is run.
Even after getting the application load address, the loading of core symbols
is complicated by the fact that the debugging symbols for the kernel are in
an ELF binary named @file{kernel.exec} while what is in memory are sections
for the PE32+ EFI binary. When @command{grub-mkimage} creates the PE32+
binary it condenses several segments from the ELF kernel binary into one
.data section in the PE32+ binary. This must be taken into account to
properly load the other non-text sections. Otherwise, GDB will work as
expected when breaking on functions, but, for instance, global variables
will point to the wrong address in memory and thus give incorrect values
(which can be difficult to debug).
Calculating the correct offsets for sections is taken care of automatically
when loading the kernel symbols via the user-defined GDB command
@command{dynamic_load_kernel_exec_symbols}, which takes one argument, the
address where the text section is loaded as determined by one of the methods
above. Alternatively, the command @command{dynamic_load_symbols} with the text
section address as an agrument can be called to load the kernel symbols and set
up loading the module symbols as they are loaded at runtime.
In the author's experience, when debugging with QEMU and OVMF, to have
debugging symbols loaded at the start of GRUB2 execution the GRUB2 EFI
application must be run via QEMU at least once prior in order to get the
load address. Two methods for obtaining the load address are described in
two subsections below. Generally speaking, the load address does not change
between QEMU runs. There are exceptions to this, namely that different
GRUB2 EFI applications can be run at different addresses. Also, it has been
observed that after running the EFI application for the first time, the
second run will sometimes have a different load address, but subsequent
runs of the same EFI application will have the same load address as the
second run. And it's a near certainty that if the GRUB EFI binary has changed,
eg. been recompiled, the load address will also be different.
This ability to predict what the load address will be allows one to assume
the load address on subsequent runs and thus load the symbols before GRUB2
starts. The following command illustrates this, assuming that QEMU is
running and waiting for a debugger connection and the current working
directory is where @file{gdb_grub} resides:
@example
gdb -x gdb_grub -ex 'dynamic_load_symbols @var{address of .text section}'
@end example
If you load the symbols in this manner and, after continuing execution, do
not see output showing the module symbols loading, then it is very likely
that the load address was incorrect.
Another thing to be aware of is how the loading of the GRUB image by the
firmware affects previously set software breakpoints. On x86 platforms,
software breakpoints are implemented by GDB by writing a special processor
instruction at the location of the desired breakpoint. This special instruction
when executed will stop the program execution and hand control to the
debugger, GDB. GDB will first save the instruction bytes that are
overwritten at the breakpoint and will put them back when the breakpoint
is hit. If GRUB is being run for the first time in QEMU, the firmware will
be loading the GRUB image into memory where every byte is already set to 0.
This means that if a breakpoint is set before GRUB is loaded, GDB will save
the 0-byte(s) where the the special instruction will go. Then when the firmware
loads the GRUB image and because it is unaware of the debugger, it will
write the GRUB image to memory, overwriting anything that was there previously ---
notably in this case the instruction that implements the software breakpoint.
This will be confusing for the person using GDB because GDB will show the
breakpoint as set, but the brekapoint will never be hit. Furthermore, GDB
then becomes confused, such that even deleting an recreating the breakpoint
will not create usable breakpoints. The @file{gdb_grub} script takes care of
this by saving the breakpoints just before they are overwritten, and then
restores them at the start of GRUB execution. So breakpoints for GRUB can be
set before GRUB is loaded, but be mindful of this effect if you are confused
as to why breakpoints are not getting hit.
Also note, that hardware breakpoints do not suffer this problem. They are
implemented by having the breakpoint address in special debug registers on
the CPU. So they can always be set freely without regard to whether GRUB has
been loaded or not. The reason that hardware breakpoints aren't always used
is because there are a limited number of them, usually around 4 on various
CPUs, and specifically exactly 4 for x86 CPUs. The @file{gdb_grub} script goes
out of its way to avoid using hardware breakpoints internally and uses them as
briefly as possible when needed, thus allowing the user to have a maximal
number at their disposal.

@node OVMF debug log
@subsection OVMF debug log
In order to get the GRUB2 load address from OVMF, first, a debug build
of OVMF must be obtained (@uref{https://github.com/retrage/edk2-nightly/raw/master/bin/DEBUGX64_OVMF.fd,
here is one} which is not officially recommended). OVMF will output debug
messages to a special serial device, which we must add to QEMU. The following
QEMU command will run the debug OVMF and write the debug messages to a
file named @file{debug.log}. It is assumed that @file{disk.img} is a disk
image or block device that is set up to boot GRUB2 EFI.
@example
qemu-system-x86_64 -bios /path/to/debug/OVMF.fd \
-drive file=disk.img,format=raw \
-device virtio-scsi-pci,id=scsi0 \
-debugcon file:debug.log -global isa-debugcon.iobase=0x402
@end example
If GRUB2 was started by the (U)EFI firmware, then in the @file{debug.log}
file one of the last lines should be a log message like:
@samp{Loading driver at 0x00006AEE000 EntryPoint=0x00006AEE756}. This
means that the GRUB2 EFI application was loaded at @samp{0x00006AEE000} and
its .text section is at @samp{0x00006AEE756}.
@node Using the gdbinfo command
@subsection Using the gdbinfo command
On EFI platforms the command @command{gdbinfo} will output a string that
is to be run in a GDB session running with the @file{gdb_grub} GDB script.

are not allowed. For instance, some commands cannot be used when the GRUB is
locked down.
The function
@code{grub_lockdown()} is used to lockdown GRUB and the function
@code{grub_is_lockdown()} function can be used to check whether lockdown is
enabled or not. When enabled, the function returns @samp{GRUB_LOCKDOWN_ENABLED}
and @samp{GRUB_LOCKDOWN_DISABLED} when is not enabled.
The following functions can be used to register the commands that can only be
used when lockdown is disabled:
