Leif Lindholm 21030a65de ia64: build fix in cache.h 
Add IA64 to the architectures excluding a declaration for
grub_arch_sync_dma_caches().

IA64 does not include any of the source files that require the function,
but was overlooked for d8901e3ba1 ("cache: Fix compilation for ppc,
sparc and arm64").

Add it to the list of excluding architectures in order to not get
missing symbol errors when running grub-mkimage.

Mathieu Trudel-Lapierre 407f685d5d video: skip 'text' gfxpayload if not supported, to fallback to default 
On UEFI, 'text' gfxpayload is not supported, but we still reach parse_modespec()
with it, which will obviously fail. Fortunately, whatever gfxpayload is set,
we still still have the 'auto' default to fall back to. Allow getting to this
fallback by not trying to parse 'text' as a modespec.

This is because 'text' correctly doesn't parse as a modespec, and ought to have
been ignored before we got to that point, just like it is immediately picked if
we're running on a system where 'text' is a supported video mode.

Michael Chang 16607eba81 f2fs: Fix gcc9 error -Werror=maybe-uninitialized 
The function grub_get_node_path() could return uninitialized offset with
level == 0 if the block is greater than direct_index + 2 * direct_blks +
2 * indirect_blks + dindirect_blks. The uninitialized offset is then used
by function grub_f2fs_get_block() because level == 0 is valid and
meaningful return to be processed.

The fix is to set level = -1 as return value by grub_get_node_path() to
signify an error that the input block cannot be handled. Any caller
should therefore check level is negative or not before processing the
output.

Alexander Graf acb3cd33f1 arm: Align section alignment with manual relocation offset code 
The arm relocation code has a manual special case for EFI binaries to
add the natural alignment to its own relocation awareness.

Since commit a51f953f4e ("mkimage: Align efi sections on 4k
boundary") we changed that alignment from 0x400 to 0x1000 bytes. Reflect
the change in that branch that we forgot as well.

This fixes running 32bit arm grub efi binaries for me again.

Alexander Graf 497438f0f5 arm: Move trampolines into code section 
When creating T32->A32 transition jumps, the relocation code in grub
will generate trampolines. These trampolines live in the .data section
of our PE binary which means they are not marked as executable.

This misbehavior was unmasked by commit a51f953f4e ("mkimage: Align
efi sections on 4k boundary") which made the X/NX boundary more obvious
because everything became page aligned.

To put things into proper order, let's move the arm trampolines into the
.text section instead. That way everyone knows they are executable.

Michael Chang b0f3e50964 hfsplus: Fix gcc9 error with -Waddress-of-packed-member 
The catkey->name could be unaligned since the address of 'void* record'
is calculated as offset in bytes to a malloc buffer.

The fix is using aligned buffer allocated by grub_malloc for holding
the UTF16 string copied from catkey->name. And use that buffer as
argument for grub_utf16_to_utf8 to convert to UTF8 strings.

In addition, using a new copy of buffer rather than catkey->name itself
for processing the endianess conversion, we can also get rid of the hunk
restoring byte order of catkey->name to what it was previously.

Heinrich Schuchardt 7195688f47 efi: Avoid NULL dereference if FilePath is NULL 
The UEFI specification allows LoadImage() to be called with a memory
location only and without a device path. In this case FilePath will not be
set in the EFI_LOADED_IMAGE_PROTOCOL.

So in function grub_efi_get_filename() the device path argument may be
NULL. As we cannot determine the device path in this case just return NULL
from the function.

This happens due to lack of support for a such usage of extern keyword

Andrew Jeddeloh f9b054242e loader/i386/linux: Calculate the setup_header length 
Previously the setup_header length was just assumed to be the size of the
linux_kernel_params struct. The linux x86 32-bit boot protocol says that the
end of the linux_i386_kernel_header is at 0x202 + the byte value at 0x201 in
the linux_i386_kernel_header. So, calculate the size of the header using the
end of the linux_i386_kernel_header, rather than assume it is the size of the
linux_kernel_params struct.

Additionally, add some required members to the linux_kernel_params
struct and align the content of linux_i386_kernel_header struct with
it. New members naming was taken directly from Linux kernel source.

linux_kernel_params and linux_i386_kernel_header structs require more
cleanup. However, this is not urgent, so, let's do this after release.

Add BIOS Boot Partition support for sparc64 platforms.  This will work a
little different than x86.  With GPT, both the OBP "load" and "boot" commands
are partition aware and neither command can see the partition table.  Therefore
the entire boot-loader is stored within the BIOS Boot Partition and nothing
is stored within the bootstrap code area of MBR.

To use it, the end user will issue the boot command with the path pointing to
the BIOS Boot Partition.

For example with the disk below:

Model: Unknown (unknown)
Disk /dev/nvme1n1: 1600GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt

Number  Start   End     Size    File system  Name  Flags

Eric Snowberg a492f4ebdb ieee1275: obdisk driver 
Add a new disk driver called obdisk for IEEE1275 platforms.  Currently
the only platform using this disk driver is SPARC, however other IEEE1275
platforms could start using it if they so choose.  While the functionality
within the current IEEE1275 ofdisk driver may be suitable for PPC and x86, it
presented too many problems on SPARC hardware.

Within the old ofdisk, there is not a way to determine the true canonical
name for the disk.  Within Open Boot, the same disk can have multiple names
but all reference the same disk.  For example the same disk can be referenced
by its SAS WWN, using this form:

/pci@302/pci@2/pci@0/pci@17/LSI,sas@0/disk@w5000cca02f037d6d,0

It can also be referenced by its PHY identifier using this form:

/pci@302/pci@2/pci@0/pci@17/LSI,sas@0/disk@p0

It can also be referenced by its Target identifier using this form:

/pci@302/pci@2/pci@0/pci@17/LSI,sas@0/disk@0

Also, when the LUN=0, it is legal to omit the ,0 from the device name.  So with
the disk above, before taking into account the device aliases, there are 6 ways
to reference the same disk.

Then it is possible to have 0 .. n device aliases all representing the same disk.
Within this new driver the true canonical name is determined using the the
IEEE1275 encode-unit and decode-unit commands when address_cells == 4.  This
will determine the true single canonical name for the device so multiple ihandles
are not opened for the same device.  This is what frequently happens with the old
ofdisk driver.  With some devices when they are opened multiple times it causes
the entire system to hang.

Another problem solved with this driver is devices that do not have a device
alias can be booted and used within GRUB. Within the old ofdisk, this was not
possible, unless it was the original boot device.  All devices behind a SAS
or SCSI parent can be found.   Within the old ofdisk, finding these disks
relied on there being an alias defined.  The alias requirement is not
necessary with this new driver.  It can also find devices behind a parent
after they have been hot-plugged.  This is something that is not possible
with the old ofdisk driver.

The old ofdisk driver also incorrectly assumes that the device pointing to by a
device alias is in its true canonical form. This assumption is never made with
this new driver.

Another issue solved with this driver is that it properly caches the ihandle
for all open devices.  The old ofdisk tries to do this by caching the last
opened ihandle.  However this does not work properly because the layer above
does not use a consistent device name for the same disk when calling into the
driver.  This is because the upper layer uses the bootpath value returned within
/chosen, other times it uses the device alias, and other times it uses the
value within grub.cfg.  It does not have a way to figure out that these devices
are the same disk.  This is not a problem with this new driver.

Due to the way GRUB repeatedly opens and closes the same disk. Caching the
ihandle is important on SPARC.  Without caching, some SAS devices can take
15 - 20 minutes to get to the GRUB menu. This ihandle caching is not possible
without correctly having the canonical disk name.

When available, this driver also tries to use the deblocker #blocks and
a way of determining the disk size.

Finally and probably most importantly, this new driver is also capable of
seeing all partitions on a GPT disk.  With the old driver, the GPT
partition table can not be read and only the first partition on the disk
can be seen.

Paul Menzel 1a2494b7c7 Makefile: Allow to set file systems modules for default_payload.elf 
By default all file system modules are added to the GRUB coreboot
payload `default_payload.elf`. This makes the image quite big,
especially as often not all modules are needed.

Introduce the variable `FS_PAYLOAD_MODULES`, which can be used to
explicitly set file systems modules to be added.

    $ make default_payload.elf
    test -f default_payload.elf && rm default_payload.elf || true

So, the resulting payload size is around 370 kB smaller. (Adding it to

be smaller.)

Colin Watson 4517db3592 gnulib: Upgrade Gnulib and switch to bootstrap tool 
Upgrade Gnulib files to 20190105.

It's much easier to maintain GRUB's use of portability support files
from Gnulib when the process is automatic and driven by a single
configuration file, rather than by maintainers occasionally running
gnulib-tool and committing the result.  Removing these
automatically-copied files from revision control also removes the
temptation to hack the output in ways that are difficult for future
maintainers to follow.  Gnulib includes a "bootstrap" program which is
designed for this.

The canonical way to bootstrap GRUB from revision control is now
"./bootstrap", but "./autogen.sh" is still useful if you just want to
generate the GRUB-specific parts of the build system.

GRUB now requires Autoconf >= 2.63 and Automake >= 1.11, in line with
Gnulib.

Gnulib source code is now placed in grub-core/lib/gnulib/ (which should
not be edited directly), and GRUB's patches are in
grub-core/lib/gnulib-patches/.  I've added a few notes to the developer
manual on how to maintain this.

Colin Watson 440ba4b011 util: Detect more I/O errors 
Many of GRUB's utilities don't check anywhere near all the possible
write errors.  For example, if grub-install runs out of space when
copying a file, it won't notice.  There were missing checks for the
return values of write, fflush, fsync, and close (or the equivalents on
other OSes), all of which must be checked.

I tried to be consistent with the existing logging practices of the
various hostdisk implementations, but they weren't entirely consistent
to start with so I used my judgement.  The result at least looks
reasonable on GNU/Linux when I provoke a write error:

  Installing for x86_64-efi platform.
  grub-install: error: cannot copy `/usr/lib/grub/x86_64-efi-signed/grubx64.efi.signed' to `/boot/efi/EFI/debian/grubx64.efi': No space left on device.

There are more missing checks in other utilities, but this should fix

Alexander Graf 18f824dd18 travis: Add Travis CI config file 
There is a really convenient service for open source project from Travis
CI: They allow for free CI testing using their infrastructure.

GRUB has had issues with broken builds for various targets for a long time
already. The main reason is a lack of CI to just do smoke tests on whether
all targets still at least compile.

This patch adds a Travis config file which builds (almost) all currently
available targets.

On top of that, this Travis config also runs a small execution test on the
x86_64-efi target.

All of this config file can easily be extended further on. It probably
makes sense to do something similar to the u-boot test infrastructure
that communicates with the payload properly. Going forward, we also will
want to do more QEMU runtime checks for other targets.

Currently, with this config alone, I already see about half of the available
targets as broken. So it's definitely desperately needed :).

Paul Menzel 3be9268318 normal/menu: Do not treat error values as key presses 
Some terminals, like `grub-core/term/at_keyboard.c`, return `-1` in case
they are not ready yet.

      if (! KEYBOARD_ISREADY (grub_inb (KEYBOARD_REG_STATUS)))
        return -1;

Currently, that is treated as a key press, and the menu time-out is
cancelled/cleared. This is unwanted, as the boot is stopped and the user
manually has to select a menu entry. Therefore, adapt the condition to
require the key value also to be greater than 0.

`GRUB_TERM_NO_KEY` is defined as 0, so the condition could be collapsed
to greater or equal than (≥) 0, but the compiler will probably do that
for us anyway, so keep the cases separate for clarity.

This is tested with coreboot, the GRUB default payload, and the
configuration file `grub.cfg` below.

For GRUB:

    $ ./autogen.sh
    $ ./configure --with-platform=coreboot
    $ make -j`nproc`
    $ make default_payload.elf

For coreboot:

    $ more grub.cfg
    serial --unit 0 --speed 115200
    set timeout=5

    menuentry 'halt' {
        halt
    }

  names.

* GRUB_EARLY_INITRD_LINUX_CUSTOM is for user created images. User
  images will be loaded after the stock images.

These separate configurations allow the distribution and user to
declare different image sets without clobbering each other.

This also makes a minor update to ensure that UUID partition labels
stay disabled when no initrd image is found, even if early images are
present.

This is basically a copy of a698240d "grub-mkconfig/10_linux: Support

- Add the zstd module to Makefile.core.def

Import zstd-1.3.6 from upstream [1]. Only the files need for decompression
are imported. I used the latest zstd release, which includes patches [2] to
build cleanly in GRUB.

I included the script used to import zstd-1.3.6 below at the bottom of the
commit message.

Upstream zstd commit hash: 4fa456d7f12f8b27bd3b2f5dfd4f46898cb31c24
Upstream zstd commit name: Merge pull request #1354 from facebook/dev

Zstd requires some posix headers, which it gets from posix_wrap.
This can be checked by inspecting the .Po files generated by automake,
which contain the header dependencies. After building run the command
`cat grub-core/lib/zstd/.deps-core/*.Po` to see the dependencies [3].
The only OS dependencies are:

- stddef.h, which is already a dependency in posix_wrap, and used for size_t
  by lzo and xz.
- stdarg.h, which comes from the grub/misc.h header, and we don't use in zstd.

All the types like uint64_t are typedefed to grub_uint64_t under the hood.
The only exception is size_t, which comes from stddef.h. This is already the
case for lzo and xz. I don't think there are any cross-compilation concerns,
because cross-compilers provide their own system headers (and it would already
be broken).

Michael Chang 84138630f1 verifiers: fix double close on pgp's sig file descriptor 
An error emerged as when I was testing the verifiers branch, so instead
of putting it in pgp prefix, the verifiers is used to reflect what the
patch is based on.

While running verify_detached, grub aborts with error.

verify_detached /@/.snapshots/1/snapshot/boot/grub/grub.cfg
/@/.snapshots/1/snapshot/boot/grub/grub.cfg.sig

alloc magic is broken at 0x7beea660: 0
Aborted. Press any key to exit.

The error is caused by sig file descriptor been closed twice, first time
in grub_verify_signature() to which it is passed as parameter. Second in
grub_cmd_verify_signature() or in whichever opens the sig file
descriptor. The second close is not consider as bug to me either, as in
common rule of what opens a file has to close it to avoid file
descriptor leakage.

After all the design of grub_verify_signature() makes it difficult to keep
a good trace on opened file descriptor from it's caller. Let's refine
the application interface to accept file path rather than descriptor, in
this way the caller doesn't have to care about closing the descriptor by
delegating it to grub_verify_signature() with full tracing to opened
file descriptor by itself.

Also making it clear that sig descriptor is not referenced in error
returning path of grub_verify_signature_init(), so it can be closed
directly by it's caller. This also makes delegating it to
grub_pubkey_close() infeasible to help in relieving file descriptor
leakage as it has to depend on uncertainty of ctxt fields in error
returning path.

Paul Menzel 91ac8687a9 unix/platform: Initialize variable to fix grub-install on UEFI system 
On a UEFI system, were no boot entry *grub* is present, currently,
`grub-install` fails with an error.

    $ efibootmgr
    BootCurrent: 0000
    Timeout: 0 seconds
    BootOrder: 0001,0006,0003,0004,0005

    Boot0004* CD/DVD/CD-RW Drive
    Boot0005  Onboard NIC
    Boot0006* WDC WD2500AAKX-75U6AA0
    $ sudo grub-install /dev/sda
    Installing for x86_64-efi platform.
    grub-install: error: efibootmgr failed to register the boot entry: Unknown error 22020.

The error code is always different, and the error message (incorrectly)
points to efibootmgr.

But, the error is in GRUB’s function
`grub_install_remove_efi_entries_by_distributor()`, where the variable
`rc` for the return value, is uninitialized and never set, when no boot
entry for the distributor is found.

The content of that uninitialized variable is then returned as the error
code of efibootmgr.

Set the variable to 0, so that success is returned, when no entry needs
to be deleted.

Tested on Dell OptiPlex 7010 with firmware A28.

    $ sudo ./grub-install /dev/sda
    Installing for x86_64-efi platform.
    Installation finished. No error reported.

Daniel Kiper 81072e718a efi: Add EFI shim lock verifier 
This module provides shim lock verification for various kernels
if UEFI secure boot is enabled on a machine.

It is recommended to put this module into GRUB2 standalone image
(avoid putting iorw and memrw modules into it; they are disallowed
if UEFI secure boot is enabled). However, it is also possible to use
it as a normal module. Though such configurations are more fragile
and less secure due to various limitations.

If the module is loaded and UEFI secure boot is enabled then:
  - module itself cannot be unloaded (persistent module),
  - the iorw and memrw modules cannot be loaded,
  - if the iorw and memrw modules are loaded then
    machine boot is disabled,
  - GRUB2 defers modules and ACPI tables verification to
    other verifiers.

Daniel Kiper 708ae9f524 verifiers: Add possibility to defer verification to other verifiers 
This way if a verifier requires verification of a given file it can defer task
to another verifier (another authority) if it is not able to do it itself. E.g.
shim_lock verifier, posted as a subsequent patch, is able to verify only PE
files. This means that it is not able to verify any of GRUB2 modules which have
to be trusted on UEFI systems with secure boot enabled. So, it can defer
verification to other verifier, e.g. PGP one.

I silently assume that other verifiers are trusted and will do good job for us.

This patch fixes above mentioned issue. Information about missing devices

Adam Williamson 4f9642a479 python: Use AM_PATH_PYTHON to determine interpreter for gentpl.py 
gentpl.py is python2/3-agnostic, but there's no way to cause it
to be run with any interpreter other than 'python', it's just
hard-coded into Makefile.common that way. Adjust that to use
AM_PATH_PYTHON (provided by automake) to find an interpreter
and run gentpl.py with that instead. This makes grub buildable
when `python` does not exist (but rather `python3` or `python2`
or `python2.7`, etc.) Minimum version is set to 2.6 as this is
the first version with `__future__.print_function` available.

Note, AM_PATH_PYTHON respects the PYTHON environment variable
and will treat its value as the *only* candidate for a valid
interpreter if it is set - when PYTHON is set, AM_PATH_PYTHON
will not try to find any alternative interpreter, it will only
check whether the interpreter set as the value of PYTHON meets
the requirements and use it if so or fail if not. This means
that when using grub's `autogen.sh`, as it too uses the value
of the PYTHON environment variable (and if it is not set, just
sets it to 'python') you cannot rely on AM_PATH_PYTHON
interpreter discovery. If your desired Python interpreter is
not just 'python', you must set the PYTHON environment variable,
e.g. 'PYTHON=/usr/local/bin/python3 ./autogen.sh'. The specified
interpreter will then be used both by autogen.sh itself and by
the autotools-driven build scripts.

This is a cryptographically signed message in MIME format.

Date: Thu, 9 Aug 2018 07:27:35 +0200

Currently, the GRUB payload for coreboot does not detect the Western
Digital hard disk WDC WD20EARS-60M AB51 connected to the ASRock E350M1,
as that takes over ten seconds to spin up.

```
disk/ahci.c:533: port 0, err: 0

disk/ahci.c:566: port: 0, err: 0
disk/ahci.c:593: port 0 is busy
disk/ahci.c:621: cleaning up failed devs
```

GRUB detects the drive, when either unloading the module *ahci*, and
then loading it again, or when doing a warm reset.

As the ten second time-out is too short, increase it to 32 seconds,
used by SeaBIOS. which detects the drive successfully.

The AHCI driver in libpayload uses 30 seconds, and that time-out was
added in commit 354066e1 (libpayload: ahci: Increase timeout for
signature reading) with the description below.

> We can't read the drives signature before it's ready, i.e. spun up.
> So set the timeout to the standard 30s. Also put a notice on the
> console, so the user knows why the signature reading failed.

Leif Lindholm 25133dfcda efi: Restrict arm/arm64 linux loader initrd placement 
The 32-bit arm Linux kernel is built as a zImage, which self-decompresses
down to near start of RAM. In order for an initrd/initramfs to be
accessible, it needs to be placed within the first ~768MB of RAM.
The initrd loader built into the kernel EFI stub restricts this down to
512MB for simplicity - so enable the same restriction in grub.

For arm64, the requirement is within a 1GB aligned 32GB window also
covering the (runtime) kernel image. Since the EFI stub loader itself
will attempt to relocate to near start of RAM, force initrd to be loaded
completely within the first 32GB of RAM.

Arindam Nath 8db0a305e4 i386/linux: Add support for ext_lfb_base 
The EFI Graphics Output Protocol can return a 64-bit
linear frame buffer address in some firmware/BIOS
implementations. We currently only store the lower
32-bits in the lfb_base. This will eventually be
passed to Linux kernel and the efifb driver will
incorrectly interpret the framebuffer address as
32-bit address.

The Linux kernel has already added support to handle
64-bit linear framebuffer address in the efifb driver
since quite some time now.

This patch adds the support for 64-bit linear frame
buffer address in GRUB to address the above mentioned
scenario.

Hans de Goede 14a3a29839 efi/console: Fix the "enter" key not working on x86 tablets 
Most 8" or 7" x86 Windows 10 tablets come with volume up/down buttons and
a power-button. In their UEFI these are almost always mapped to arrow
up/down and enter.

Pressing the volume buttons (sometimes by accident) will stop the
menu countdown, but the power-button / "enter" key was not being recognized
as enter, so the user would be stuck at the grub menu.

The problem is that these tablets send scan_code 13 or 0x0d for the
power-button, which officialy maps to the F3 key. They also set
unicode_char to 0x0d.

This commit recognizes the special case of both scan_code and unicode_char
being set to 0x0d and treats this as an enter key press.

This fixes things getting stuck at the grub-menu and allows the user
to choice a grub-menu entry using the buttons on the tablet.

Daniel Kiper 14ed7207b1 xfs: Accept filesystem with sparse inodes 
The sparse inode metadata format became a mkfs.xfs default in
xfsprogs-4.16.0, and such filesystems are now rejected by grub as
containing an incompatible feature.

In essence, this feature allows xfs to allocate inodes into fragmented
freespace.  (Without this feature, if xfs could not allocate contiguous
space for 64 new inodes, inode creation would fail.)

In practice, the disk format change is restricted to the inode btree,
which as far as I can tell is not used by grub.  If all you're doing
today is parsing a directory, reading an inode number, and converting
that inode number to a disk location, then ignoring this feature
should be fine, so I've added it to XFS_SB_FEAT_INCOMPAT_SUPPORTED

I did some brief testing of this patch by hacking up the regression
tests to completely fragment freespace on the test xfs filesystem, and
then write a large-ish number of inodes to consume any existing
contiguous 64-inode chunk.  This way any files the grub tests add and
traverse would be in such a fragmented inode allocation.  Tests passed,
but I'm not sure how to cleanly integrate that into the test harness.

Jaegeuk Kim 203047c756 fs: Add F2FS support 
"F2FS (Flash-Friendly File System) is flash-friendly file system which was merged
into Linux kernel v3.8 in 2013.

The motive for F2FS was to build a file system that from the start, takes into
account the characteristics of NAND flash memory-based storage devices (such as
solid-state disks, eMMC, and SD cards).

F2FS was designed on a basis of a log-structured file system approach, which
remedies some known issues of the older log structured file systems, such as
the snowball effect of wandering trees and high cleaning overhead. In addition,
since a NAND-based storage device shows different characteristics according to
its internal geometry or flash memory management scheme (such as the Flash
Translation Layer or FTL), it supports various parameters not only for
configuring on-disk layout, but also for selecting allocation and cleaning
algorithm.", quote by https://en.wikipedia.org/wiki/F2FS.

The source codes for F2FS are available from:

This patch fixes the build error by cleaning up the ambiguity of placing
aligned structure in a packed one. In "struct grub_btrfs_time" and "struct
grub_gpt_part_type", the aligned attribute seems to be superfluous, and also
has to be packed, to ensure the structure is bit-to-bit mapped to the format
laid on disk. I think we could blame to copy and paste error here for the
mistake. In "struct efi_variable", we have to use grub_efi_packed_guid_t, as

Add support for multiple, shared, early initrd images. These early
images will be loaded in the order declared, and all will be loaded
before the initrd image.

While many classes of data can be provided by early images, the
immediate use case would be for distributions to provide CPU
microcode to mitigate the Meltdown and Spectre vulnerabilities.

There are two environment variables provided for declaring the early
images.

* GRUB_EARLY_INITRD_LINUX_STOCK is for the distribution declare
  images that are provided by the distribution or installed packages.
  If undeclared, this will default to a set of common microcode image
  names.

* GRUB_EARLY_INITRD_LINUX_CUSTOM is for user created images. User
  images will be loaded after the stock images.

These separate configurations allow the distribution and user to
declare different image sets without clobbering each other.

This also makes a minor update to ensure that UUID partition labels
stay disabled when no initrd image is found, even if early images are
present.

Peter Jones b9b9002952 mkimage: avoid copying relocations for sections that won't be copied. 
Some versions of gcc include a plugin called "annobin", and in some
build systems this is enabled by default.  This plugin creates special
ELF note sections to track which ABI-breaking features are used by a
binary, as well as a series of relocations to annotate where.

If grub is compiled with this feature, then when grub-mkimage translates
the binary to another file format which does not strongly associate
relocation data with sections (i.e. when platform is *-efi), these
relocations appear to be against the .text section rather than the
original note section.  When the binary is loaded by the PE runtime
loader, hilarity ensues.

This issue is not necessarily limited to the annobin, but could arise
any time there are relocations in sections that are not represented in
grub-mkimage's output.

This patch seeks to avoid this issue by only including relocations that
refer to sections which will be included in the final binary.

As an aside, this should also obviate the need to avoid -funwind-tables,
-fasynchronous-unwind-tables, and any sections similar to .eh_frame in
the future.  I've tested it on x86-64-efi with the following gcc command
line options (as recorded by -grecord-gcc-flags), but I still need to
test the result on some other platforms that have been problematic in
the past (especially ARM Aarch64) before I feel comfortable making

Colin Watson 9363f738ba libgcrypt: Import replacement CRC operations 
The CRC implementation imported from libgcrypt 1.5.3 is arguably
non-free, due to being encumbered by the restrictive Internet Society
licence on RFCs (see e.g. https://wiki.debian.org/NonFreeIETFDocuments).
Fortunately, libgcrypt has since replaced it with a version that is both
reportedly better-optimised and doesn't suffer from this encumbrance.

The ideal solution would be to update to a new version of libgcrypt, and
I spent some time trying to do that.  However, util/import_gcry.py
requires complex modifications to cope with the new version, and I
stalled part-way through; furthermore, GRUB's libgcrypt tree already
contains some backports of upstream changes.  Rather than allowing the
perfect to be the enemy of the good, I think it's best to backport this
single change to at least sort out the licensing situation.  Doing so
won't make things any harder for a future wholesale upgrade.

This commit is mostly a straightforward backport of
https://git.gnupg.org/cgi-bin/gitweb.cgi?p=libgcrypt.git;a=commitdiff;h=06e122baa3321483a47bbf82fd2a4540becfa0c9,
but I also imported bufhelp.h from libgcrypt 1.7.0 (newer versions
required further changes elsewhere).

I've tested that "hashsum -h crc32" still produces correct output for a
variety of files on both i386-pc and x86_64-emu targets.

Daniel Kiper 5826e32c37 chainloader: Fix wrong break condition (must be AND not, OR) 
The definition of bpb's num_total_sectors_16 and num_total_sectors_32
is that either the 16-bit field is non-zero and is used (in which case
eg mkfs.fat sets the 32-bit field to zero), or it is zero and the
32-bit field is used. Therefore, a BPB is invalid only if *both*
fields are zero; having one field as zero and the other as non-zero is
the case to be expected. (Indeed, according to Microsoft's specification
one of the fields *must* be zero, and the other non-zero.)

This affects all users of grub_chainloader_patch_bpb which are in
chainloader.c, freedos.c, and ntldr.c

Some descriptions of the semantics of these two fields:

https://www.win.tue.nl/~aeb/linux/fs/fat/fat-1.html

  The old 2-byte fields "total number of sectors" and "number of
  sectors per FAT" are now zero; this information is now found in
  the new 4-byte fields.

(Here given in the FAT32 EBPB section but the total sectors 16/32 bit
fields semantic is true of FAT12 and FAT16 too.)

https://wiki.osdev.org/FAT#BPB_.28BIOS_Parameter_Block.29

  19 | 2 | The total sectors in the logical volume. If this value is 0,
  it means there are more than 65535 sectors in the volume, and the actual
  count is stored in "Large Sectors (bytes 32-35).

  32 | 4 | Large amount of sector on media. This field is set if there
  are more than 65535 sectors in the volume.

(Doesn't specify what the "large" field is set to when unused, but as
mentioned mkfs.fat sets it to zero then.)

https://technet.microsoft.com/en-us/library/cc976796.aspx

  0x13 | WORD | 0x0000 |
  Small Sectors . The number of sectors on the volume represented in 16
  bits (< 65,536). For volumes larger than 65,536 sectors, this field
  has a value of zero and the Large Sectors field is used instead.

  0x20 | DWORD | 0x01F03E00 |
  Large Sectors . If the value of the Small Sectors field is zero, this
  field contains the total number of sectors in the FAT16 volume. If the
  value of the Small Sectors field is not zero, the value of this field
  is zero.

https://staff.washington.edu/dittrich/misc/fatgen103.pdf page 10

  BPB_TotSec16 | 19 | 2 |
  This field is the old 16-bit total count of sectors on the volume.
  This count includes the count of all sectors in all four regions of the
  volume. This field can be 0; if it is 0, then BPB_TotSec32 must be
  non-zero. For FAT32 volumes, this field must be 0. For FAT12 and
  FAT16 volumes, this field contains the sector count, and
  BPB_TotSec32 is 0 if the total sector count “fits” (is less than
  0x10000).

  BPB_TotSec32 | 32 | 4 |
  This field is the new 32-bit total count of sectors on the volume.
  This count includes the count of all sectors in all four regions of the
  volume. This field can be 0; if it is 0, then BPB_TotSec16 must be
  non-zero. For FAT32 volumes, this field must be non-zero. For
  FAT12/FAT16 volumes, this field contains the sector count if
  BPB_TotSec16 is 0 (count is greater than or equal to 0x10000).

(This specifies that an unused BPB_TotSec32 field is set to zero.)

By the way fix offsets in include/grub/fat.h.

Stefan Fritsch d97d20da82 ahci: Improve error handling 
Check the error bits in the interrupt status register. According to the
AHCI 1.2 spec, "Interrupt sources that are disabled (‘0’) are still
reflected in the status registers.", so this should work even though
grub uses polling

This fixes the following problem on a Fujitsu E744 laptop:

Sometimes there is a very long delay (up to several minutes) when
booting from hard disk. It seems accessing the DVD drive (which has no
disk inserted) sometimes fails with some errors, which leads to each
access being stalled until the 20s timeout triggers. This seems to
happen when grub is trying to read filesystem/partition data.

The problem is that the command_issue bit that is checked in the loop is
only reset if the "HBA receives a FIS which clears the BSY, DRQ, and ERR
bits for the command", but the ERR bit is never cleared. Therefore
command_issue is never reset and grub waits for the timeout.

The relevant bit in our case is the Task File Error Status (TFES), which
is equivalent to the ERR bit 0 in tfd. But this patch also checks
the other error bits except for the "Interface non-fatal error status"
bit.

to descend the boot order using "exit" entries, such as PXE -> HD boot
scenarios.

Alexander Graf e224ee31c0 efi: Move grub_reboot() into kernel 
The reboot function calls machine_fini() and then reboots the system.
Currently it lives in lib/ which means it gets compiled into the
reboot module which lives on the heap.

In a following patch, I want to free the heap on machine_fini()
though, so we would free the memory that the code is running in. That
obviously breaks with smarter UEFI implementations.

So this patch moves it into the core. That way we ensure that all
code running after machine_fini() in the UEFI case is running from
memory that got allocated (and gets deallocated) by the UEFI core.

Konrad Rzeszutek Wilk 90d8ca6970 Fix util/grub.d/20_linux_xen.in: Add xen_boot command support for aarch64 
Commit d33045ce7f introduced
the support for this, but it does not work under x86 (as it stops
20_linux_xen from running).

The 20_linux_xen is run under a shell and any exits from within it:

(For example on x86):
+ /usr/bin/grub2-file --is-arm64-efi /boot/xen-4.9.0.gz
[root@tst063 grub]# echo $?
1

will result in 20_linux_xen exiting without continuing
and also causing grub2-mkconfig to stop processing.

As in:

 [root@tst063 grub]# ./grub-mkconfig | tail
 Generating grub configuration file ...
 Found linux image: /boot/vmlinuz-4.13.0-0.rc5.git1.1.fc27.x86_64

 }

 ### END /usr/local/etc/grub.d/10_linux ###

 ### BEGIN /usr/local/etc/grub.d/20_linux_xen ###

And no more.

This patch wraps the invocation of grub-file to be a in subshell
and to process the return value in a conditional. That fixes
the issue.

Patrick Steinhardt 2da5f067f4 unix exec: avoid atexit handlers when child exits 
The `grub_util_exec_redirect_all` helper function can be used to
spawn an executable and redirect its output to some files. After calling
`fork()`, the parent will wait for the child to terminate with
`waitpid()` while the child prepares its file descriptors, environment
and finally calls `execvp()`. If something in the children's setup
fails, it will stop by calling `exit(127)`.

Calling `exit()` will cause any function registered via `atexit()` to be
executed, which is usually the wrong thing to do in a child. And
actually, one can easily observe faulty behaviour on musl-based systems
without modprobe(8) installed: executing `grub-install --help` will call
`grub_util_exec_redirect_all` with "modprobe", which obviously fails if
modprobe(8) is not installed. Due to the child now exiting and invoking
the `atexit()` handlers, it will clean up some data structures of the
parent and cause it to be deadlocked in the `waitpid()` syscall.

The issue can easily be fixed by calling `_exit(127)` instead, which is
especially designed to be called when the atexit-handlers should not be
executed.

Pali Rohár 682b3134b6 * grub-core/fs/udf.c: Add support for UUID 
Use same algorithm as in libblkid from util-linux v2.30.

1. Take first 16 bytes from UTF-8 encoded string of VolumeSetIdentifier
2. If all bytes are hexadecimal digits, convert to lowercase and use as UUID
3. If first 8 bytes are not all hexadecimal digits, convert those 8 bytes
   to their hexadecimal representation, resulting in 16 bytes for UUID
4. Otherwise, compose UUID from two parts:
   1. part: converted first 8 bytes (which are hexadecimal digits) to lowercase
   2. part: encoded following 4 bytes to their hexadecimal representation (16 bytes)

So UUID would always have 16 hexadecimal digits in lowercase variant.

According to UDF specification, first 16 Unicode characters of
VolumeSetIdentifier should be unique value and first 8 should be
hexadecimal characters.

In most cases all 16 characters are hexadecimal, but e.g. MS Windows
format.exe set only first 8 as hexadecimal and remaining as fixed
(non-unique) which violates specification.

Eric Biggers 4aaa6b639d Allow GRUB to mount ext2/3/4 filesystems that have the encryption feature. 
On such a filesystem, inodes may have EXT4_ENCRYPT_FLAG set.
For a regular file, this means its contents are encrypted; for a
directory, this means the filenames in its directory entries are
encrypted; and for a symlink, this means its target is encrypted.  Since
GRUB cannot decrypt encrypted contents or filenames, just issue an error
if it would need to do so.  This is sufficient to allow unencrypted boot
files to co-exist with encrypted files elsewhere on the filesystem.

(Note that encrypted regular files and symlinks will not normally be
encountered outside an encrypted directory; however, it's possible via
hard links, so they still need to be handled.)

Tested by booting from an ext4 /boot partition on which I had run
'tune2fs -O encrypt'.  I also verified that the expected error messages
are printed when trying to access encrypted directories, files, and
symlinks from the GRUB command line.  Also ran 'sudo ./grub-fs-tester
ext4_encrypt'; note that this requires e2fsprogs v1.43+ and Linux v4.1+.

Paulo Flabiano Smorigo 5696d56d33 Add Virtual LAN support. 
This patch adds support for virtual LAN (VLAN) tagging. VLAN tagging allows
multiple VLANs in a bridged network to share the same physical network link
but maintain isolation:

H.J. Lu 1c4dc293df x86-64: Treat R_X86_64_PLT32 as R_X86_64_PC32 
Starting from binutils commit bd7ab16b4537788ad53521c45469a1bdae84ad4a:

https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=bd7ab16b4537788ad53521c45469a1bdae84ad4a

x86-64 assembler generates R_X86_64_PLT32, instead of R_X86_64_PC32, for
32-bit PC-relative branches.  Grub2 should treat R_X86_64_PLT32 as
R_X86_64_PC32.

Michael Chang 721b4677ab Fix packed-not-aligned error on GCC 8 
When building with GCC 8, there are several errors regarding packed-not-aligned.

./include/grub/gpt_partition.h:79:1: error: alignment 1 of ‘struct grub_gpt_partentry’ is less than 8 [-Werror=packed-not-aligned]

This patch fixes the build error by cleaning up the ambiguity of placing
aligned structure in a packed one. In "struct grub_btrfs_time" and "struct
grub_gpt_part_type", the aligned attribute seems to be superfluous, and also
has to be packed, to ensure the structure is bit-to-bit mapped to the format
laid on disk. I think we could blame to copy and paste error here for the
mistake. In "struct efi_variable", we have to use grub_efi_packed_guid_t, as
the name suggests. :)

Michael Marineau 44f54cbf43 gpt: write backup GPT first, skip if inaccessible. 
Writing the primary GPT before the backup may lead to a confusing
situation: booting a freshly updated system could consistently fail and
next boot will fall back to the old system if writing the primary works
but writing the backup fails. If the backup is written first and fails
the primary is left in the old state so the next boot will re-try and
possibly fail in the exact same way. Making that repeatable should make
it easier for users to identify the error.

Additionally if the firmware and OS disagree on the disk size, making
the backup inaccessible to GRUB, then just skip writing the backup.
When this happens the automatic call to `coreos-setgoodroot` after boot
will take care of repairing the backup.

Michael Marineau e4d25afd18 gpt: prefer disk size from header over firmware 
The firmware and the OS may disagree on the disk configuration and size.
Although such a setup should be avoided users are unlikely to know about
the problem, assuming everything behaves like the OS. Tolerate this as
best we can and trust the reported on-disk location over the firmware
when looking for the backup GPT. If the location is inaccessible report
the error as best we can and move on.

Michael Marineau 1f5d29420c gpt: be more careful about relocating backup header 
The header was being relocated without checking the new location is
actually safe. If the BIOS thinks the disk is smaller than the OS then
repair may relocate the header into allocated space, failing the final
validation check. So only move it if the disk has grown.

Additionally, if the backup is valid then we can assume its current
location is good enough and leave it as-is.

Matthew Garrett ec0051a569 Don't allocate a new address buffer if we receive multiple responses 
The current logic in the DNS resolution code allocates an address buffer
based on the number of addresses in the response packet. If we receive
multiple response packets in response to a single query packet, this means
that we will reallocate a new buffer large enough for only the addresses in
that specific packet, discarding any previous results in the process. Worse,
we still keep track of the *total* number of addresses resolved in response
to this query, not merely the number in the packet being currently processed.
Use realloc() rather than malloc() to avoid overwriting the existing data,
and allocate a buffer large enough for the total set of addresses rather
than merely the number in this specific response.

sprintf() doesn't seem to support the full set of format conversions, so
fix this in the nasty way.

Matthew Garrett 76fb8e4341 Fix race in EFI validation 
The Secure Boot code currently reads the kernel from disk, validates the
signature and then reads it from disk again. A sufficiently exciting storage
device could modify the kernel between these two events and trigger the
execution of an untrusted kernel. Avoid re-reading it in order to ensure
this isn't a problem, and in the process speed up boot by not reading the
kernel twice.

Matthew Garrett 9b669efb38 Fail validation if we can't find shim and Secure Boot is enabled 
If grub is signed with a key that's in the trusted EFI keyring, an attacker
can point a boot entry at grub rather than at shim and grub will fail to
locate the shim verification protocol. This would then allow booting an
arbitrary kernel image. Fail validation if Secure Boot is enabled and we
can't find the shim protocol in order to prevent this.

Colin Watson 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.

Michael Marineau f82f65f338 gpt: start new GPT module 
This module is a new implementation for reading GUID Partition Tables
which is much stricter than the existing part_gpt module and exports GPT
data directly instead of the generic grub_partition structure. It will
be the basis for modules that need to read/write/update GPT data.

The current code does nothing more than read and verify the table.

Apparently some distros like Debian provide C.UTF-8 but it isn't
actually fully supported by glibc and thus is not available on all
systems, neither Gentoo nor Fedora provide it.

1 Notes on the Free Translation Project
***************************************
Free software is going international! The Free Translation Project is
a way to get maintainers of free software, translators, and users all
together, so that free software will gradually become able to speak many
languages. A few packages already provide translations for their
messages.
If you found this `ABOUT-NLS' file inside a distribution, you may
assume that the distributed package does use GNU `gettext' internally,
itself available at your nearest GNU archive site. But you do _not_
need to install GNU `gettext' prior to configuring, installing or using
this package with messages translated.
Installers will find here some useful hints. These notes also
explain how users should proceed for getting the programs to use the
available translations. They tell how people wanting to contribute and
work on translations can contact the appropriate team.
When reporting bugs in the `intl/' directory or bugs which may be
related to internationalization, you should tell about the version of
`gettext' which is used. The information can be found in the
`intl/VERSION' file, in internationalized packages.
1.1 Quick configuration advice
==============================
If you want to exploit the full power of internationalization, you
should configure it using
./configure --with-included-gettext
to force usage of internationalizing routines provided within this
package, despite the existence of internationalizing capabilities in the
operating system where this package is being installed. So far, only
the `gettext' implementation in the GNU C library version 2 provides as
many features (such as locale alias, message inheritance, automatic
charset conversion or plural form handling) as the implementation here.
It is also not possible to offer this additional functionality on top
of a `catgets' implementation. Future versions of GNU `gettext' will
very likely convey even more functionality. So it might be a good idea
to change to GNU `gettext' as soon as possible.
So you need _not_ provide this option if you are using GNU libc 2 or
you have installed a recent copy of the GNU gettext package with the
included `libintl'.
1.2 INSTALL Matters
===================
Some packages are "localizable" when properly installed; the programs
they contain can be made to speak your own native language. Most such
packages use GNU `gettext'. Other packages have their own ways to
internationalization, predating GNU `gettext'.
By default, this package will be installed to allow translation of
messages. It will automatically detect whether the system already
provides the GNU `gettext' functions. If not, the included GNU
`gettext' library will be used. This library is wholly contained
within this package, usually in the `intl/' subdirectory, so prior
installation of the GNU `gettext' package is _not_ required.
Installers may use special options at configuration time for changing
the default behaviour. The commands:
./configure --with-included-gettext
./configure --disable-nls
will, respectively, bypass any pre-existing `gettext' to use the
internationalizing routines provided within this package, or else,
_totally_ disable translation of messages.
When you already have GNU `gettext' installed on your system and run
configure without an option for your new package, `configure' will
probably detect the previously built and installed `libintl.a' file and
will decide to use this. This might not be desirable. You should use
the more recent version of the GNU `gettext' library. I.e. if the file
`intl/VERSION' shows that the library which comes with this package is
more recent, you should use
./configure --with-included-gettext
to prevent auto-detection.
The configuration process will not test for the `catgets' function
and therefore it will not be used. The reason is that even an
emulation of `gettext' on top of `catgets' could not provide all the
extensions of the GNU `gettext' library.
Internationalized packages usually have many `po/LL.po' files, where
LL gives an ISO 639 two-letter code identifying the language. Unless
translations have been forbidden at `configure' time by using the
`--disable-nls' switch, all available translations are installed
together with the package. However, the environment variable `LINGUAS'
may be set, prior to configuration, to limit the installed set.
`LINGUAS' should then contain a space separated list of two-letter
codes, stating which languages are allowed.
1.3 Using This Package
======================
As a user, if your language has been installed for this package, you
only have to set the `LANG' environment variable to the appropriate
`LL_CC' combination. Here `LL' is an ISO 639 two-letter language code,
and `CC' is an ISO 3166 two-letter country code. For example, let's
suppose that you speak German and live in Germany. At the shell
prompt, merely execute `setenv LANG de_DE' (in `csh'),
`export LANG; LANG=de_DE' (in `sh') or `export LANG=de_DE' (in `bash').
This can be done from your `.login' or `.profile' file, once and for
all.
You might think that the country code specification is redundant.
But in fact, some languages have dialects in different countries. For
example, `de_AT' is used for Austria, and `pt_BR' for Brazil. The
country code serves to distinguish the dialects.
The locale naming convention of `LL_CC', with `LL' denoting the
language and `CC' denoting the country, is the one use on systems based
on GNU libc. On other systems, some variations of this scheme are
used, such as `LL' or `LL_CC.ENCODING'. You can get the list of
locales supported by your system for your language by running the
command `locale -a | grep '^LL''.
Not all programs have translations for all languages. By default, an
English message is shown in place of a nonexistent translation. If you
understand other languages, you can set up a priority list of languages.
This is done through a different environment variable, called
`LANGUAGE'. GNU `gettext' gives preference to `LANGUAGE' over `LANG'
for the purpose of message handling, but you still need to have `LANG'
set to the primary language; this is required by other parts of the
system libraries. For example, some Swedish users who would rather
read translations in German than English for when Swedish is not
available, set `LANGUAGE' to `sv:de' while leaving `LANG' to `sv_SE'.
Special advice for Norwegian users: The language code for Norwegian
bokma*l changed from `no' to `nb' recently (in 2003). During the
transition period, while some message catalogs for this language are
installed under `nb' and some older ones under `no', it's recommended
for Norwegian users to set `LANGUAGE' to `nb:no' so that both newer and
older translations are used.
In the `LANGUAGE' environment variable, but not in the `LANG'
environment variable, `LL_CC' combinations can be abbreviated as `LL'
to denote the language's main dialect. For example, `de' is equivalent
to `de_DE' (German as spoken in Germany), and `pt' to `pt_PT'
(Portuguese as spoken in Portugal) in this context.
1.4 Translating Teams
=====================
For the Free Translation Project to be a success, we need interested
people who like their own language and write it well, and who are also
able to synergize with other translators speaking the same language.
Each translation team has its own mailing list. The up-to-date list of
teams can be found at the Free Translation Project's homepage,
`http://www.iro.umontreal.ca/contrib/po/HTML/', in the "National teams"
area.
If you'd like to volunteer to _work_ at translating messages, you
should become a member of the translating team for your own language.
The subscribing address is _not_ the same as the list itself, it has
`-request' appended. For example, speakers of Swedish can send a
message to `sv-request@li.org', having this message body:
subscribe
Keep in mind that team members are expected to participate
_actively_ in translations, or at solving translational difficulties,
rather than merely lurking around. If your team does not exist yet and
you want to start one, or if you are unsure about what to do or how to
get started, please write to `translation@iro.umontreal.ca' to reach the
coordinator for all translator teams.
The English team is special. It works at improving and uniformizing
the terminology in use. Proven linguistic skills are praised more than
programming skills, here.
1.5 Available Packages
======================
Languages are not equally supported in all packages. The following
matrix shows the current state of internationalization, as of October
2006. The matrix shows, in regard of each package, for which languages
PO files have been submitted to translation coordination, with a
translation percentage of at least 50%.
# Matrix here is removed!
Some counters in the preceding matrix are higher than the number of
visible blocks let us expect. This is because a few extra PO files are
used for implementing regional variants of languages, or language
dialects.
For a PO file in the matrix above to be effective, the package to
which it applies should also have been internationalized and
distributed as such by its maintainer. There might be an observable
lag between the mere existence a PO file and its wide availability in a
distribution.
If October 2006 seems to be old, you may fetch a more recent copy of
this `ABOUT-NLS' file on most GNU archive sites. The most up-to-date
matrix with full percentage details can be found at
`http://www.iro.umontreal.ca/contrib/po/HTML/matrix.html'.
1.6 Using `gettext' in new packages
===================================
If you are writing a freely available program and want to
internationalize it you are welcome to use GNU `gettext' in your
package. Of course you have to respect the GNU Library General Public
License which covers the use of the GNU `gettext' library. This means
in particular that even non-free programs can use `libintl' as a shared
library, whereas only free software can use `libintl' as a static
library or use modified versions of `libintl'.
Once the sources are changed appropriately and the setup can handle
the use of `gettext' the only thing missing are the translations. The
Free Translation Project is also available for packages which are not
developed inside the GNU project. Therefore the information given above
applies also for every other Free Software Project. Contact
`translation@iro.umontreal.ca' to make the `.pot' files available to
the translation teams.

# The set of defined variables is at the end of this script.
# Known limitations:
# - On IRIX 6.5 with CC="cc", the run time search patch must not be longer

# known workaround is to choose shorter directory names for the build
# directory and/or the installation directory.
# All known linkers require a '.a' archive for static linking (except MSVC,

Usage: $ME [OPTIONS] [ARGS]
Convert git log output to ChangeLog format. If present, any ARGS
are passed to "git log". To avoid ARGS being parsed as options to
$ME, they may be preceded by '--'.
OPTIONS:
--amend=FILE FILE maps from an SHA1 to perl code (i.e., s/old/new/) that
makes a change to SHA1's commit log text or metadata.
--append-dot append a dot to the first line of each commit message if
there is no other punctuation or blank at the end.
--no-cluster never cluster commit messages under the same date/author
header; the default is to cluster adjacent commit messages
if their headers are the same and neither commit message
contains multiple paragraphs.
--srcdir=DIR the root of the source tree, from which the .git/
directory can be derived.
--since=DATE convert only the logs since DATE;
the default is to convert all log entries.
--format=FMT set format string for commit subject and body;
see 'man git-log' for the list of format metacharacters;
the default is '%s%n%b%n'
--strip-tab remove one additional leading TAB from commit message lines.
--strip-cherry-pick remove data inserted by "git cherry-pick";
this includes the "cherry picked from commit ..." line,
and the possible final "Conflicts:" paragraph.
--help display this help and exit
--version output version information and exit
EXAMPLE:
$ME --since=2008-01-01 > ChangeLog
$ME -- -n 5 foo > last-5-commits-to-branch-foo
SPECIAL SYNTAX:
The following types of strings are interpreted specially when they appear
at the beginning of a log message line. They are not copied to the output.
Copyright-paperwork-exempt: Yes
Append the "(tiny change)" notation to the usual "date name email"
ChangeLog header to mark a change that does not require a copyright
assignment.
Co-authored-by: Joe User <user\@example.com>
List the specified name and email address on a second
ChangeLog header, denoting a co-author.
Signed-off-by: Joe User <user\@example.com>
These lines are simply elided.
In a FILE specified via --amend, comment lines (starting with "#") are ignored.
FILE must consist of <SHA,CODE+> pairs where SHA is a 40-byte SHA1 (alone on
a line) referring to a commit in the current project, and CODE refers to one
or more consecutive lines of Perl code. Pairs must be separated by one or
more blank line.
Here is sample input for use with --amend=FILE, from coreutils:

/* _GL_WARN_ON_USE (function, "literal string") issues a declaration
for FUNCTION which will then trigger a compiler warning containing
the text of "literal string" anywhere that function is called, if
supported by the compiler. If the compiler does not support this
feature, the macro expands to an unused extern declaration.
This macro is useful for marking a function as a potential
portability trap, with the intent that "literal string" include
instructions on the replacement function that should be used
instead. However, one of the reasons that a function is a
portability trap is if it has the wrong signature. Declaring
FUNCTION with a different signature in C is a compilation error, so
this macro must use the same type as any existing declaration so
that programs that avoid the problematic FUNCTION do not fail to
compile merely because they included a header that poisoned the
function. But this implies that _GL_WARN_ON_USE is only safe to
use if FUNCTION is known to already have a declaration. Use of
this macro implies that there must not be any other macro hiding
the declaration of FUNCTION; but undefining FUNCTION first is part
of the poisoning process anyway (although for symbols that are
provided only via a macro, the result is a compilation error rather
than a warning containing "literal string"). Also note that in
C++, it is only safe to use if FUNCTION has no overloads.
For an example, it is possible to poison 'getline' by:
- adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
[getline]) in configure.ac, which potentially defines
HAVE_RAW_DECL_GETLINE
- adding this code to a header that wraps the system <stdio.h>:
#undef getline
#if HAVE_RAW_DECL_GETLINE
_GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
"not universally present; use the gnulib module getline");
#endif
It is not possible to directly poison global variables. But it is
possible to write a wrapper accessor function, and poison that
(less common usage, like &environ, will cause a compilation error
rather than issue the nice warning, but the end result of informing
the developer about their portability problem is still achieved):
#if HAVE_RAW_DECL_ENVIRON
static char ***rpl_environ (void) { return &environ; }
_GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
# undef environ
# define environ (*rpl_environ ())
#endif

@node Gnulib
@section Gnulib
Gnulib is a source code library that provides basic functionality to
programs and libraries. Many software packages make use of Gnulib
to avoid reinventing the portability wheel.
GRUB imports Gnulib using its @command{bootstrap} utility, identifying a
particular Git commit in @file{bootstrap.conf}. To upgrade to a new Gnulib
commit, set @code{GNULIB_REVISION} in @file{bootstrap.conf} to the new commit
ID, then run @kbd{./bootstrap} and whatever else you need to make sure it
works. Check for changes to Gnulib's @file{NEWS} file between the old and new
commits; in some cases it will be necessary to adjust GRUB to match. You may
also need to update the patches in @file{grub-core/lib/gnulib-patches/}.
To add a new Gnulib module or remove one that is no longer needed, change
@code{gnulib_modules} in @file{bootstrap.conf}. Again, run @kbd{./bootstrap}
and whatever else you need to make sure it works.
Bootstrapping from an older distribution containing gettext version < 0.18.3,
will require a patch similar to this to be applied first before running the
@command{./bootstrap} utility:

@node Verifiers framework
@chapter Verifiers framework
To register your own verifier call @samp{grub_verifier_register} with a structure
pointing to your functions.
The interface is inspired by the hash interface with @samp{init}/@samp{write}/@samp{fini}.
There are essentially 2 ways of using it, hashing and whole-file verification.
With the hashing approach:
During @samp{init} you decide whether you want to check the given file and init context.
In @samp{write} you update your hashing state.
In @samp{fini} you check that the hash matches the expected value/passes some check/...
With whole-file verification:
During @samp{init} you decide whether you want to check the given file and init context.
In @samp{write} you verify the file and return an error if it fails.
You don't have @samp{fini}.
Additional @samp{verify_string} receives various strings like kernel parameters
to verify. Returning no error means successful verification and an error stops
the current action.
Detailed description of the API:
Every time a file is opened your @samp{init} function is called with file descriptor
and file type. Your function can have the following outcomes:
@itemize
@item returning no error and setting @samp{*flags} to @samp{GRUB_VERIFY_FLAGS_DEFER_AUTH}.
In this case verification is deferred to other active verifiers. Verification
fails if nobody cares or selected verifier fails.
@item returning no error and setting @samp{*flags} to @samp{GRUB_VERIFY_FLAGS_SKIP_VERIFICATION}.
In this case your verifier will not be called anymore and it is assumed to have
skipped verification.
@item returning no error and not setting @samp{*flags} to @samp{GRUB_VERIFY_FLAGS_SKIP_VERIFICATION}
In this case verification is done as described in the following section.
@item returning an error. Then opening of the file will fail due to failed verification.
@end itemize
In the third case your @samp{write} will be called with chunks of the file. If
you need the whole file in a single chunk then during @samp{init} set the bit
@samp{GRUB_VERIFY_FLAGS_SINGLE_CHUNK} in @samp{*flags}. During @samp{init} you
may set @samp{*context} if you need additional context. At every iteration you
may return an error and the file will be considered as having failed the
verification. If you return no error then verification continues.
Optionally at the end of the file @samp{fini}, if it exists, is called with just
the context. If you return no error during any of @samp{init}, @samp{write} and
@samp{fini} then the file is considered as having succeded verification.

@node Root Identifcation Heuristics
@section Root Identifcation Heuristics
If the target operating system uses the Linux kernel, @command{grub-mkconfig}
attempts to identify the root file system via a heuristic algoirthm. This
algorithm selects the identification method of the root file system by
considering three factors. The first is if an initrd for the target operating
system is also present. The second is @samp{GRUB_DISABLE_LINUX_UUID} and if set
to @samp{true}, prevents @command{grub-mkconfig} from identifying the root file
system by its UUID. The third is @samp{GRUB_DISABLE_LINUX_PARTUUID} and if set
to @samp{true}, prevents @command{grub-mkconfig} from identifying the root file
system via the UUID of its enclosing partition. If the variables are assigned
any other value, that value is considered equivalent to @samp{false}. The
variables are also considered to be set to @samp{false} if they are not set.
When booting, the Linux kernel will delegate the task of mounting the root
filesystem to the initrd. Most initrd images determine the root file system by
checking the Linux kernel's command-line for the @samp{root} key and use its
value as the identification method of the root file system. To improve the
reliability of booting, most initrd images also allow the root file system to be
identified by its UUID. Because of this behavior, the @command{grub-mkconfig}
command will set @samp{root} to @samp{root=UUID=...} to provide the initrd with
the filesystem UUID of the root file system.
If no initrd is detected or @samp{GRUB_DISABLE_LINUX_UUID} is set to @samp{true}
then @command{grub-command} will identify the root filesystem by setting the
kernel command-line variable @samp{root} to @samp{root=PARTUUID=...} unless
@samp{GRUB_DISABLE_LINUX_PARTUUID} is also set to @samp{true}. If
@samp{GRUB_DISABLE_LINUX_PARTUUID} is also set to @samp{true},
@command{grub-command} will identify by its Linux device name.
The following table summarizes the behavior of the @command{grub-mkconfig}
command.

@node UEFI secure boot and shim
@section UEFI secure boot and shim support
The GRUB, except the @command{chainloader} command, works with the UEFI secure
boot and the shim. This functionality is provided by the shim_lock module. It
is recommend to build in this and other required modules into the @file{core.img}.
All modules not stored in the @file{core.img} and the ACPI tables for the
@command{acpi} command have to be signed, e.g. using PGP. Additionally, the
@command{iorw}, the @command{memrw} and the @command{wrmsr} commands are
prohibited if the UEFI secure boot is enabled. This is done due to
security reasons. All above mentioned requirements are enforced by the
shim_lock module. And itself it is a persistent module which means that
it cannot be unloaded if it was loaded into the memory.
@node Measured Boot
@section Measuring boot components
If the tpm module is loaded and the platform has a Trusted Platform Module
installed, GRUB will log each command executed and each file loaded into the
TPM event log and extend the PCR values in the TPM correspondingly. All events
will be logged into the PCR described below with a type of EV_IPL and an
event description as described below.
@multitable @columnfractions 0.3 0.1 0.6

@end multitable
GRUB will not measure its own @file{core.img} - it is expected that firmware
will carry this out. GRUB will also not perform any measurements until the
tpm module is loaded. As such it is recommended that the tpm module be built
into @file{core.img} in order to avoid a potential gap in measurement between
@file{core.img} being loaded and the tpm module being loaded.
Measured boot is currently only supported on EFI platforms.

@section Firmware stalls instead of booting GRUB
The EFI implementation of some older MacBook laptops stalls when it gets
presented a grub-mkrescue ISO image for x86_64-efi target on an USB stick.
Affected are models of year 2010 or earlier. Workaround is to zeroize the
bytes 446 to 461 of the EFI partition, where mformat has put a partition table
entry which claims partition start at block 0. This change will not hamper
bootability on other machines.
