	ieee1275: NULL pointer dereference in grub_ieee1275_encode_devname()
	Function grub_strndup() may return NULL, this is called from
	function grub_ieee1275_get_devname() which is then called from
	function grub_ieee1275_encode_devname() to set device. The device
	variable could then be used with a NULL pointer.

	docs/grub-dev: Change comments rules
	Current comments forms are annoying, so, some of them are disallowed
	starting from now. New rules are more flexible and mostly aligned
	with, e.g., Linux kernel comments rules.

	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.
	Just in case...

	ieee1275: Include a.out header in assembly of sparc64 boot loader
	Recent versions of binutils dropped support for the a.out and COFF
	formats on sparc64 targets. Since the boot loader on sparc64 is
	supposed to be an a.out binary and the a.out header entries are
	rather simple to calculate in our case, we just write the header
	ourselves instead of relying on external tools to do that.

	net/dhcp: Add explicit net_dhcp command
	Mostly for cosmetic reasons, we add a "net_dhcp" command, which is (at the
	moment) identical to the existing "net_bootp" command. Both actually trigger
	a DHCP handshake now, and both should be able to deal with pure BOOTP servers.
	We could think about dropping the DHCP options from the initial DISCOVER packet
	when the user issues the net_bootp command, but it's unclear whether this is
	really useful, as both protocols should be able to coexist.

	net/dhcp: Actually send out DHCPv4 DISCOVER and REQUEST messages
	Even though we were parsing some DHCP options sent by the server, so far
	we are only using the BOOTP 2-way handshake, even when talking to a DHCP
	server.

	Change this by actually sending out DHCP DISCOVER packets instead of the
	generic (mostly empty) BOOTP BOOTREQUEST packets.

	A pure BOOTP server would ignore the extra DHCP options in the DISCOVER
	packet and would just reply with a BOOTREPLY packet, which we also
	handle in the code.

	net/dhcp: Allow receiving DHCP OFFER and ACK packets
	In respone to a BOOTREQUEST packet a BOOTP server would answer with a BOOTREPLY
	packet, which ends the conversation for good. DHCP uses a 4-way handshake,
	where the initial server respone is an OFFER, which has to be answered with
	REQUEST by the client again, only to be completed by an ACKNOWLEDGE packet
	from the server.

	Teach the grub_net_process_dhcp() function to deal with OFFER packets,
	and treat ACK packets the same es BOOTREPLY packets.

	net/dhcp: Use DHCP options for name and bootfile
	The BOOTP RFC describes the boot file name and the server name as being part
	of the integral BOOTP data structure, with some limits on the size of them.
	DHCP extends this by allowing them to be separate DHCP options, which is more
	flexible.

	Teach the code dealing with those fields to check for those DHCP options first
	and use this information, if provided. We fall back to using the BOOTP
	information if those options are not used.

	net/dhcp: Introduce per-interface timeout
	Currently we have a global timeout for all network cards in the BOOTP/DHCP

	Make this timeout a per-interface one, so better accommodate the upcoming

	will come with.

	find *a particular* option field. Use that new function in places where we

	msr: Add new MSR modules (rdmsr/wrmsr)
	In order to be able to read from and write to model-specific registers,
	two new modules are added. They are i386 specific, as the cpuid module.

	rdmsr module registers the command rdmsr that allows reading from a MSR.
	wrmsr module registers the command wrmsr that allows writing to a MSR.

	wrmsr module is disabled if UEFI secure boot is enabled.

	Please note that on SMP systems, interacting with a MSR that has a scope
	per hardware thread, implies that the value only applies to the
	particular cpu/core/thread that ran the command.

	Also, if you specify a reserved or unimplemented MSR address, it will
	cause a general protection exception (which is not currently being
	handled) and the system will reboot.

	sparc64: Add bios boot partition support
	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
	1      1049kB  1075MB  1074MB   ext3
	2      1075MB  1076MB  1049kB                     bios_grub
	3      1076MB  1600GB  1599GB                     lvm

	To boot grub2 from OBP, you would use:

	boot /pci@302/pci@1/pci@0/pci@13/nvme@0/disk@1:b

	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.

	So, the resulting payload size is around 370 kB smaller. (Adding it to
	the CBFS, it will be compressed, so the effective size difference will
	be smaller.)

	windows/platform.c: Fix compilation errors

2019-03-05  Colin Watson  <cjwatson@ubuntu.com>

	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.

	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 :).

	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:

	tpm: Fix bug in GRUB2 TPM module
	The value of tpm_handle changes between successive calls to grub_tpm_handle_find(),
	as instead of simply copying the stored pointer we end up taking the address of
	said pointer when using the cached value of grub_tpm_handle.

	This causes grub_efi_open_protocol() to return a nullptr in grub_tpm2_execute()
	and grub_tpm2_log_event(). Said nullptr goes unchecked and
	efi_call_5(tpm->hash_log_extend_event,...) ends up jumping to 0x0, Qemu crashes
	once video ROM is reached at 0xb0000.

	This patch seems to do the trick of fixing that bug, but we should also ensure

	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.

	Xen has also support to load microcode updates provided as additional
	modules by the bootloader.

	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.

	zstd: Import upstream zstd-1.3.6
	- Import zstd-1.3.6 from upstream
	- Add zstd's module.c file
	- 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).

	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.

	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

	osdep/linux: Convert partition start to disk sector length
	When reading data off a disk, sector values are based on the disk sector
	length.

	Within grub_util_fd_open_device(), the start of the partition was taken
	directly from grub's partition information structure, which uses the
	internal sector length (currently 512b), but never transformed to the
	disk's sector length.

	Subsequent calculations were all wrong for devices that have a diverging
	sector length and the functions eventually skipped to the wrong stream
	location, reading invalid data.

	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.

	ahci: Increase time-out from 10 s to 32 s
	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:539: port 0, err: 0
	disk/ahci.c:543: 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.

	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.

	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.

	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.

	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:

	http://git.kernel.org/cgit/linux/kernel/git/jaegeuk/f2fs.git
	http://git.kernel.org/cgit/linux/kernel/git/jaegeuk/f2fs-tools.git

	This patch has been integrated in OpenMandriva Lx 3.

	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. :)

	efi/uga: Fix PCIe LER when GRUB2 accesses non-enabled MMIO data from VGA
	A GPU inserted into a PCIe I/O slot disappears during system startup.
	The problem centers around GRUB and a specific VGA init function in
	efi_uga.c. This causes an LER (Link Error Recorvery) because the MMIO
	memory has not been enabled before attempting access.

	The fix is to add the same coding used in other VGA drivers, specifically
	to add a check to insure that it is indeed a VGA controller. And then
	enable the MMIO address space with the specific bits.

	grub-mkconfig/10_linux: Support multiple early initrd images
	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.

	This is a continuation of a previous patch published by Christian

	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

	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

	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.

	  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.)

	However, we will also have other issues here, like lack of access to OF

	Add block-list GPT support for SPARC.  The OBP "load" and "boot" methods

	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.

	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.

	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

	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

	util/grub.d/20_linux_xen.in: Add xen_boot command support for aarch64
	This patch adds the support of xen_boot command for aarch64:
	    xen_hypervisor
	    xen_module
	These two commands are only for aarch64, since it has its own protocol and
	commands to boot xen hypervisor and Dom0, but not multiboot.

	For other architectures, they are still using multiboot and module
	commands.

	arm64: Add "--nounzip" option support in xen_module command
	This patch adds "--nounzip" option support in order to
	be compatible with the module command of multiboot on other architecture,
	by this way we can simplify grub-mkconfig support code.

	This patch also allow us to use zip compressed module(like Linux kernel
	for Dom0).

	arm_coreboot: Support EHCI.

	ehci: Split core  code from PCI part.
	On ARM often EHCI is present without PCI and just declared in device
	tree. So splitcore from PCI part.

	arm_coreboot: Support DMA.
	This is needed to support USB and some other busses.

	arm_coreboot: Support loading linux images.

	arm_coreboot: Support grub-mkstandalone.

	arm_coreboot: Support keyboard for vexpress.

	at_keyboard: Split protocol from controller code.
	On vexpress controller is different but protocol is the same, so reuse the
	code.

	arm-coreboot: Export FDT routines.
	We need to use them from modules as well.

	arm-coreboot: Support for vexpress timer.

	Add support for device-tree-based drivers.

	arm-coreboot: Start new port.

	Rename uboot/datetime to dummy/datetime.
	It's just a stub and is not UBoot-specific.

	Rename uboot/halt.c to dummy/halt.c.
	It's not U-Boot specific and it's a stub.

	coreboot: Split parts that are platform-independent.
	We currently assume that coreboot is always i386, it's no longer the case,
	so split i386-coreboot parts from generic coreboot code.

	Refactor arm-uboot code to make it genereic.
	arm-coreboot startup code can be very similar to arm-uboot but current code has
	U-Boot specific references. So split U-Boot part from generic part.

	mkimage: Pass layout to mkimage_generate_elfXX rather than some fields.
	This allows easier extension of this function without having too long of
	arguments list.

	check read offset and read either from block list or from fragments as
	appropriate.

	2. Support sparse files with zero blocks.

	3. Fix fragment read - frag.offset is absolute fragment position,
	not offset relative to ino.chunk.

	In particular, the current documentation refers to the "number or

	We need to use -Werror to avoid warning-generated case to be accepted.
	Clang uses -nopie rather than -no-pie. Check both and use whichever one works.
	Additionally android clang passes -pie to the linker even though it doesn't

	While this is fixed in current autoconf GIT, we really cannot force everyone
	to use bleeding edge (that is not even released right now). So run test under

	Fix fwpath in efi netboot
	The path returned by grub_efi_net_config has already been stripped for the
	directory part extracted from cached bootp packet. We should just return the
	result to avoild it be stripped again.

	It fixed the problem that grub.efi as NBP image always looking for grub.cfg and
	platform directory in upper folder rather than current one it gets loaded while
	$prefix is empty. The behavior is inconsistent with other architecture and how
	we would expect empty $prefix going to be in general.

	The only exception to the general rule of empty $prefix is that when loaded
	from platform directory itself, the platform part is stripped thus upper folder
	is used for looking up files. It meets the case for how grub-mknetdir lay out
	the files under tftp root directory, but also hide away this issue to be
	identified as it appears to be just works.

	Also fix possible memory leak by moving grub_efi_get_filename() call after

	ofnet: implement the receive buffer
	get_card_packet() from ofnet.c allocates a netbuff based on the device's MTU:

	 nb = grub_netbuff_alloc (dev->mtu + 64 + 2);

	In the case when the MTU is large, and the received packet is
	relatively small, this leads to allocation of significantly more memory,
	than it's required. An example could be transmission of TFTP packets
	with 0x400 blksize via a network card with 0x10000 MTU.

	This patch implements a per-card receive buffer in a way similar to efinet.c,
	and makes get_card_packet() allocate a netbuff of the received data size.

	bootp: export next server IP as environment variable
	Network boot autoconfiguration sets default server to next server IP
	(siaddr) from BOOTP/DHCP reply, but manual configuration using net_bootp
	exports only server name. Unfortunately semantic of server name is not
	clearly defined. BOOTP RFC 951 defines it only for client request, and
	DHCP RFC 1541 only mentions it, without any implied usage. It looks like
	this field is mostly empty in server replies.

	Export next server IP as net_<interface>_next_server variable. This allows
	grub configuration script to set $root/$prefix based on information obtained
	by net_bootp.

	xen: add capability to load p2m list outside of kernel mapping
	Modern pvops linux kernels support a p2m list not covered by the

	In case the elf-note is set by the kernel don't place the p2m list
	into the kernel mapping, but map it to the given address. This will
	allow to support domains with larger memory, as the kernel mapping is

	multiboot2: Add support for relocatable images
	Currently multiboot2 protocol loads image exactly at address specified in
	ELF or multiboot2 header. This solution works quite well on legacy BIOS
	platforms. It is possible because memory regions are placed at predictable
	addresses (though I was not able to find any spec which says that it is
	strong requirement, so, it looks that it is just a goodwill of hardware
	designers). However, EFI platforms are more volatile. Even if required
	memory regions live at specific addresses then they are sometimes simply
	not free (e.g. used by boot/runtime services on Dell PowerEdge R820 and
	OVMF). This means that you are not able to just set up final image
	destination on build time. You have to provide method to relocate image
	contents to real load address which is usually different than load address
	specified in ELF and multiboot2 headers.

	This patch provides all needed machinery to do self relocation in image code.
	First of all GRUB2 reads min_addr (min. load addr), max_addr (max. load addr),
	align (required image alignment), preference (it says which memory regions are
	preferred by image, e.g. none, low, high) from multiboot_header_tag_relocatable
	header tag contained in binary (at this stage load addresses from multiboot2
	and/or ELF headers are ignored). Later loader tries to fulfill request (not only
	that one) and if it succeeds then it informs image about real load address via
	multiboot_tag_load_base_addr tag. At this stage GRUB2 role is finished. Starting
	from now executable must cope with relocations itself using whole static and
	dynamic knowledge provided by boot loader.

	This patch does not provide functionality which could do relocations using
	ELF relocation data. However, I was asked by Konrad Rzeszutek Wilk and Vladimir
	'phcoder' Serbinenko to investigate that thing. It looks that relevant machinery
	could be added to existing code (including this patch) without huge effort.
	Additionally, ELF relocation could live in parallel with self relocation provided
	by this patch. However, during research I realized that first of all we should
	establish the details how ELF relocatable image should look like and how it should
	be build. At least to build proper test/example files.

	So, this patch just provides support for self relocatable images. If ELF file
	with relocs is loaded then GRUB2 complains loudly and ignores it. Support for
	such files will be added later.

	This patch was tested with Xen image which uses that functionality. However, this Xen
	feature is still under development and new patchset will be released in about 2-3 weeks.

	multiboot2: Do not pass memory maps to image if EFI boot services are enabled
	If image requested EFI boot services then skip multiboot2 memory maps.
	Main reason for not providing maps is because they will likely be
	invalid. We do a few allocations after filling them, e.g. for relocator
	needs. Usually we do not care as we would have finished boot services.
	If we keep boot services then it is easier/safer to not provide maps.
	However, if image needs memory maps and they are not provided by bootloader
	then it should get itself just before ExitBootServices() call.

	net: fix ipv6 routing
	ipv6 routing in grub2 is broken, we cannot talk to anything outside our local
	network or anything that doesn't route in our global namespace.  This patch
	fixes this by doing a couple of things

	1) Read the router information off of the router advertisement.  If we have a
	router lifetime we need to take the source address and create a route from it.

	2) Changes the routing stuff slightly to allow you to specify a gateway _and_ an
	interface.  Since the router advertisements come in on the link local address we
	need to associate it with the global address on the card.  So when we are
	processing the router advertisement, either use the SLAAC interface we create
	and add the route to that interface, or loop through the global addresses we
	currently have on our interface and associate it with one of those addresses.
	We need to have a special case here for the default route so that it gets used,
	we do this by setting the masksize to 0 to mean it encompasses all networks.
	The routing code will automatically select the best route so if there is a
	closer match we will use that.

	With this patch I can now talk to ipv6 addresses outside of my local network.

	menu_entry: Disable cursor during update_screen()
	When running grub in a VGA console of a KVM pseries guest on PowerPC,
	you can see the cursor sweeping over the whole line when entering a
	character in editor mode. This is visible because grub always refreshes
	the whole line when entering a character in editor mode, and drawing
	characters is quite a slow operation with the firmware used for the
	powerpc pseries guests (SLOF).
	To avoid this ugliness, the cursor should be disabled when refreshing
	the screen contents during update_screen().

	support modules without symbol table
	all_video module does not have any code or data and exists solely for
	.moddeps section to pull in dependencies. This makes all symbols unneeded.

	While in current binutils (last released version as of this commit is 2.26)
	``strip --strip-unneeded'' unintentionally adds section symbols for each
	existing section, this behavior was considered a bug and changed in commit
	14f2c699ddca1e2f706342dffc59a6c7e23e844c to completely strip symbol table
	in this case.

	Older binutils (verified with 2.17) and some other toolchains (at least
	elftoolchain r3223M), both used in FreeBSD, remove symbol table in all_video
	as well.

	Relax run-time check and do not return error for modules without symbol table.
	Add additional checks to module verifier to make sure such modules

	a) have non-empty .moddeps section. Without either externally visible symbols
	or .moddeps modules are completely useless and should not be built.

	b) do not have any relocations.

	Closes: 46986

	10_linux: avoid multi-device root= kernel argument
	If root filesystem is multidev btrfs, do not attempt to pass all devices as
	kernel root= argument. This results in splitting command line in GRUB due to
	embedded newline and even if we managed to quote it, kernel does not know how
	to interpret it anyway. Multidev btrfs requires user space device scanning,

	configure: Add -fno-unwind-tables if supported.
	Unwind tables are useless for us bt consume space if present. Ensure that they

	module-verifier: allow limited-range relocations on sparc64.
	clang as incomplete mcmodel=large support. As we don't currently need full
	mcmodel=large support for sparc64, relax those checks.

	Disable build-time module check on emu.
	On emu some checks can be laxer like check for relocation range. Additionally
	module loading in emu is rarely used. So skip this check rather than making
	it laxer for all platforms. In ideal we may want to have slightly different
	check for emu but for now this is good enough.

	configure: Fix grub_cv_cc_fno_unwind_tables check.
	Check tries -fno-dwarf2-cfi-asm but adds -fno-asynchronous-unwind-tables
	to TARGET_CFLAGS. Fix this.

	Add -mno-stack-arg-probe on mingw.
	This argument disables generation of calls to __chkstk_ms. Those calls are
	useless on GRUB as function is dummy. Yet they increase module size and
	use limited-range relocations which may not work under some memory layouts.
	We currently don't use such layouts on concerned platforms but lt's correct
	this.

	Strip .ARM.exidx
	This section is generated by clang and is useful only for debugging.
	It contains exotic relocations, so strip them to avoid them interferring

	This was lost when code was refactored. Patch restores previous behavior.

	It is still not clear whether this is the right one. Due to the way we

	generic detection which ends up in assuming parent device is BIOS disk.

	It is useful to install GRUB on VM disk from the host. But it also means
	that GRUB will mistakenly allow install on real system as well.

	For now let's fix regression; future behavior needs to be discussed.

	and still incorrect if GPT was created using different logical block size.
	But current code is obviously wrong and new has better chances to be correct.

	lsefimmap: support persistent memory and other UEFI 2.5 features
	This should accompany
		76ce1de740 Translate UEFI persistent memory type

	1. Add a string for the EfiPersistentMemory type 14 that was
	added in UEFI 2.5.

	2. Decode the memory attributes that were added in UEFI 2.5:
	* NV (non-volatile)
	* MORE_RELIABLE (higher reliable, e.g., mirrored memory in a system
	  with partial memory mirroring)
	* RO (read-only)

	3. Use proper IEC binary units (KiB, MiB, etc.) for power-of-two
	values rather than misusing SI power-of-ten units (KB, MB, etc.)

	4. The lsmmap command only decodes memory ranges sizes up to GiB scale
	units.  Persistent memory ranges will reach into the TiB scale.
	Since 64-bit size field supports TiB, PiB, and EiB, decode all of
	them for completeness.

	5. In the lsefimmap command, rewrite the print statements to
	* avoid rounding
	* avoid a big nested if/else tree.

	For example: In the sixth entry below, the value of 309MB implies
	316416KB but is really reporting 316436KB.

	Widen the size column to 6 digits to accommodate typical cases.
	The worst case value would require 14 digits; if that happens,
	let the columns get out of sync.

	Old format:

	tcp: ack when we get an OOO/lost packet
	While adding tcp window scaling support I was finding that I'd get some packet
	loss or reordering when transferring from large distances and grub would just
	timeout.  This is because we weren't ack'ing when we got our OOO packet, so the
	sender didn't know it needed to retransmit anything, so eventually it would fill
	the window and stop transmitting, and we'd time out.  Fix this by ACK'ing when
	we don't find our next sequence numbered packet.  With this fix I no longer time
	out.  Thanks,

	For GCC this is simply -mabi=32. While clang supports this option as well,
	o32 ABI is valid for MIPS target and n32/64 ABI are valid for MIPS64 target
	only, so use "-target mips/mipsel -mabi=32".

	progress: avoid NULL dereference for net files
	From original patch by dann frazier <dann.frazier@canonical.com>:

	  grub_net_fs_open() saves off a copy of the file structure it gets passed and
	  uses it to create a bufio structure. It then overwrites the passed in file
	  structure with this new bufio structure. Since file->name doesn't get set
	  until we return back to grub_file_open(), it means that only the bufio
	  structure gets a valid file->name. The "real" file's name is left
	  uninitialized. This leads to a crash when the progress module hook is called
	  on it.

	grub_net_fs_open() already saved copy of file name as ->net->name, so change
	progress module to use it.

	Also, grub_file_open may leave file->name as NULL if grub_strdup fails. Check
	for it.

	file: ignore host disk in blocklist check
	It cannot work anyway because host disk cannot be read. This fixes hostfs access
	on native Windows build where filenames start with '\' or do not have initial
	separator at all (d:\foo).

	Issue was observed when running grub-fstest on Windows. On UNIX image name is
	canonicalized to always start with `/' so this was not noticed.

	This has side effect of allowing relative path names on host, but this already
	was the case with `ls' command, so it just extends it to all commands.

	makes grub think that we've not sent anything.  So since we have the SNP stuff

	archelp: Never pass NULL as mtime.
	Moves complexity from fs code (NULL check) to common code (passing non-NULL).

	HFS: Convert to fshelp.
	HFS doesn't handle "." and ".." properly. Convert it to fshelp to reuse the
	logic.

	FAT: Convert to fshelp.
	exFAT doesn't handle "." and ".." correctly, convert it to fshelp to
	reuse the same logic.

	BFS: Convert to fshelp.
	BFS doesn't handle ".." correctly, so convert it to fshelp to reuse the logic.

	fshelp: Add handling of "." and ".." and grub_fshelp_find_file_lookup.
	Recent tests have discovered that many of our filesystems have flawed
	handling of "." and "..". Rather than attempting to fix it in filesystems
	themselves, make the common code fshelp aware of "." and ".." and handle
	them in this layer. Add grub_fshelp_find_file_lookup for easy conversion
	of BFS, HFS and exFAT which have the same problem and don't use fshelp.

	Switch procfs to use archelp.
	This fixes handling of "." and "..".

	grub-install: Use a+ in fopen rather than r+.
	r+ does not create a file if none exists.

	bootp: ignore gateway_ip (relay) field.
	From RFC1542:

	   The 'giaddr' field is rather poorly named.  It exists to facilitate
	   the transfer of BOOTREQUEST messages from a client, through BOOTP
	   relay agents, to servers on different networks than the client.
	   Similarly, it facilitates the delivery of BOOTREPLY messages from the
	   servers, through BOOTP relay agents, back to the client.  In no case
	   does it represent a general IP router to be used by the client.  A
	   BOOTP client MUST set the 'giaddr' field to zero (0.0.0.0) in all
	   BOOTREQUEST messages it generates.

	   A BOOTP client MUST NOT interpret the 'giaddr' field of a BOOTREPLY
	   message to be the IP address of an IP router.  A BOOTP client SHOULD
	   completely ignore the contents of the 'giaddr' field in BOOTREPLY
	   messages.

	Leave code ifdef'd out for the time being in case we see regression.

	efinet: open Simple Network Protocol exclusively
	EDK2 network stack is based on Managed Network Protocol which is layered

	polling races with grub for received (and probably trasmitted) packets
	which causes either serious slowdown or complete failure to load files.

	Open SNP device exclusively.  This destroys all child MNP instances and
	stops background polling.

	Exclusive open cannot be done when enumerating cards, as it would destroy
	PXE information we need to autoconfigure interface; and it cannot be done
	during autoconfiguration as we need to do it for non-PXE boot as well. So
	move SNP open to card ->open method and add matching ->close to clean up.

	efinet: skip virtual IPv4 and IPv6 devices when enumerating cards
	EDK2 PXE driver creates two child devices - IPv4 and IPv6 - with
	bound SNP instance. This means we get three cards for every physical
	adapter when enumerating. Not only is this confusing, this may result
	in grub ignoring packets that come in via the "wrong" card.

	Example of device hierarchy is

	 Ctrl[91] PciRoot(0x0)/Pci(0x3,0x0)
	   Ctrl[95] PciRoot(0x0)/Pci(0x3,0x0)/MAC(525400123456,0x1)
	     Ctrl[B4] PciRoot(0x0)/Pci(0x3,0x0)/MAC(525400123456,0x1)/IPv4(0.0.0.0)

	Skip PXE created virtual devices when enumerating cards. Make sure to
	find real card when applying initial autoconfiguration during PXE boot,

2015-03-27  Steve McIntyre  <steve@einval.com>

	Recognize EFI platform even in case of mismatch between Linux and EFI.
	Some x86 systems might be capable of running a 64-bit Linux kernel but
	only use a 32-bit EFI (e.g. Intel Bay Trail systems). It's useful for
	grub-install to be able to recognise such systems, to set the default
	x86 platform correctly.

	To allow grub-install to know the size of the firmware rather than
	just the size of the kernel, there is now an extra EFI sysfs file to
	describe the underlying firmware. Read that if possible, otherwise
	fall back to the kernel type as before.

2015-03-03  Vladimir Serbinenko  <phcoder@gmail.com>

	Remove emu libusb support.
	It's disabled by default and has been broken for a long time.
	As nobody is interested in fixing and maintaining it, remove it.

	configure.ac: Remove unused COND_clang

	Remove libgcc dependency.
	libgcc for boot environment isn't always present and compatible.
	libgcc is often absent if endianness or bit-size at boot is different
	from running OS.
	libgcc may use optimised opcodes that aren't available on boot time.
	So instead of relying on libgcc shipped with the compiler, supply
	the functions in GRUB directly.
	Tests are present to ensure that those replacement functions behave the
	way compiler expects them to.

	types.h: Use __builtin_bswap* with clang.
	clang pretends to be GCC 4.2 but we use __builtin_bswap* only with GCC 4.3+.
	clang support __builtin_bswap*, so use it.

	configure.ac: Set $CPPFLAGS when checking for no_app_regs.
	Fixes compilation for sparc64 with clang.

	Add -msoft-float alongside clang arguments to specify ABI.
	Specify ABI in asm files explicitly.
	This trigers asm warning due to gcc failing to propagate -msoft-float
	but it's tolerable.

	Add missing grub_ prefix in memcpy invocation

	Allow clang compilation for thumb with -mthumb-interwork.
	clang already uses -mthumb-interwork behaviour even thout it doesn't
	support the option.

	arm64: Fix compilation failure.
	Don't supply +nosimd to asm files.
	Otherwise +nosimd coming from flags forbids some of instructions
	used in cache_flush.

	Supply signed division to fix ARM compilation.
	Previously we supplied only unsigned divisions on platforms that need software
	division.
	Yet compiler may itself use a signed division. A typical example would be a
	difference between 2 pointers which involves division by object size.

	qemu: Switch to more portable .org
	Binary is checked identical.

	qemu: Fix GateA20 enabling.
	GateA20 code was inactive due to address error.

	qemu: Fix compilation

	Remove realmode.S from coreboot and qemu.
	It's not used there.

	Remove obsolete ADDR32 and DATA32 checks.

	i386: Remove needless ADDR32 prefixes when address is known and fixed.
	Shaves off 6 bytes in lzma_decompress.img.

	i386-pc/boot: Explicitly mark kernel_address[_high] as local.
	Otherwise apple asm might try to make accesses relocatable.

	Change dot assignmnet to more portable .org.
	Binary is unchanged (verified)

	i386: Move from explicit ADDR32/DATA32 prefixes to instruction suffixes.
	Is more portable.

	Argument is not used on x86, hence it's gone unnoticed.

	Found by: Coverity scan.

	disk/AFsplitter: check argument validity before doing any allocs.
	This avoids possible memory leaks.

	Found by: Coverity scan.

	commands/wildcard: Add missing free.
	Found by: Coverity scan.

	commands/verify: Fix sha1 context zeroing-out.
	Current code doesn't zero-out context completely. It's a minor issue
	really as sha1 init already takes care of initing the context.

	commands/tr: Simplify and fix missing parameter test.
	Found by: Coverity scan

	commands/syslinux: Add missing free.
	Found by: Coverity scan.

	commands/parttool: Add missing device close.

	Found by: Coverity scan.

	commands/macbless: Fix potential overflow.
	Is a minor concern as no such FS would be created under normal circumstances
	and failure was benign.

	Found by: Coverity scan.

	commands/file: Change the confusing loop stop condition.
	Old condition was used to zero-out header variable on exit of the loop.
	This is correct but confusing. Replace with in-loop logic.

	Found by: Coverity Scan.

	commands/acpi: Use ALIGN_UP rather than manual expression.

	uhci: Fix null pointer dereference.
	Found by: Coverity scan.

	Always add -msoft-float to avoid compiler generating float arithmetics.

	Generate empty ChangeLog if no .git is available.
	When making dist from a git snapshot without repo available make dist would
	fail to find ChangeLog. Generate empty ChangeLog if no ChangeLog is already
	present and repo is not available.

	Makefile.am: Fix Changelog cutoff address.
	gitlog-to-changelog Doesn't generate entries for cutoff day, only
	for days after the cutoff date, adjust by one to compensate.

	efidisk: Return the determined root disk even if partition is unknown.

	util/grub-mkrescue.c: Always include part_msdos and part_gpt on EFI.
	When booted from stick, EFI would use GPT partition and our root
	device detection algortihm depends on GRUB's ability to see the same
	partitions. Hence include msdos and gpt partmap modules on EFI even when
	they're not needed to access root filesystem.

	conf/Makefile.common: Remove unused {LD,C}FLAGS_CPU.

	Autogenerate ChangeLog from git changelog.
	Old ChangeLog is moved to ChangeLog-2015. For all changes starting from
	this one ChangeLog will be generated from gitlog only on explicit make
	invocation and make dist.

	Mention platform "none" in NEWS

	accept also hdX as alias to native Xen disk name
	To be compatible with legacy pv-grub, sort disks by increasing order of handle
	value. This allows reusing legacy pv-grub menu.lst which is using hdX names.
