        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 d8901e3ba115 ("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.

        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.

        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.

        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 a51f953f4ee87 ("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.

        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 a51f953f4ee87 ("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.

        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

        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

        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

        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.

        Makefile: Allow to set file systems modules for default_payload.elf
        By default all file system modules are added to the GRUB coreboot

        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.

        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

        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.

            $ ./configure --with-platform=coreboot
            $ make -j`nproc`

        efi: Rename armxx to arch
        Some architectures want to boot Linux as plain UEFI binary. Today that
        really only encompasses ARM and AArch64, but going forward more
        architectures may adopt that model.

        So rename our internal API accordingly.

        mkimage: Clarify file alignment in efi case
        There are a few spots in the PE generation code for EFI binaries that uses
        the section alignment rather than file alignment, even though the alignment
        is really only file bound.

        Replace those cases with the file alignment constant instead.

        mkimage: Align efi sections on 4k boundary
        There is UEFI firmware popping up in the wild now that implements stricter
        permission checks using NX and write protect page table entry bits.

        This means that firmware now may fail to load binaries if its individual
        sections are not page aligned, as otherwise it can not ensure permission
        boundaries.

        So let's bump all efi section alignments up to 4k (EFI page size). That way
        we will stay compatible going forward.

        Unfortunately our internals can't deal very well with a mismatch of alignment
        between the virtual and file offsets, so we have to also pad our target
        binary a bit.

        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
        that all calls to grub_efi_open_protocol() are checked so that we don't start
        executing low memory.

        grub-mkconfig/20_linux_xen: 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.

        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.

        This is basically a copy of a698240d "grub-mkconfig/10_linux: Support
        multiple early initrd images" by Matthew S. Turnbull.

        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.

        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

        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.

        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.

        GRUB detects the drive, when either unloading the module *ahci*, and

        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.

        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:

        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

        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.

        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

        grub_aout_load() has a grub_file_t parameter, and depending on what order
        includes land in, it's sometimes not defined.  This patch explicitly adds
        file.h to aout.h so that it will always be defined.

        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.

        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.

        sparc64: fix OF path names for sun4v systems

        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.

        * 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.

        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+.

        Don't use devspec to determine the OBP path on SPARC hardware.  Within all

        only autofs entry exists, attempt to trigger mount by opening mount point
        and retry. Mount point itself is then kept open to avoid timeout.

        glibc 2.25 still includes sys/sysmacros.h in sys/types.h but also emits

        compilation fails because we use -Werror by default.

        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
        -Werror as well to force proper detection.

        This should have no impact on autoconf 2.70+ as AC_HEADER_MAJOR in this version

        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.

        Network boot autoconfiguration sets default server to next server IP

        xen: add capability to load p2m list outside of kernel mapping
        Modern pvops linux kernels support a p2m list not covered by the
        kernel mapping. This capability is flagged by an elf-note specifying
        the virtual address the kernel is expecting the p2m list to be mapped
        to.

        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
        limited to 2GB and a domain with huge memory in the TB range will have
        a p2m list larger than this.

        xen: modify page table construction
        Modify the page table construction to allow multiple virtual regions
        to be mapped. This is done as preparation for removing the p2m list
        from the initial kernel mapping in order to support huge pv domains.

        This allows a cleaner approach for mapping the relocator page by
        using this capability.

        The interface to the assembler level of the relocator has to be changed
        in order to be able to process multiple page table areas.

        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.

        ieee1275: prevent buffer over-read
        Prevent buffer over-read in grub_machine_mmap_iterate. This was
        causing phys_base from being calculated properly. This then
        caused the wrong value to be placed in ramdisk_image within
        struct linux_hdrs. Which prevented the ramdisk from loading on
        boot.

        Newer SPARC systems contain more than 8 available memory entries.

        For example on a T5-8 with 2TB of memory, the memory layout could
        look like this:

        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

        v2: add run-time check for empty symbol table if relocations are present as
            suggested by Vladimir.

        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,
        so passing single device would not work too.

        This still respects user settings GRUB_DISABLE_LINUX_UUID. Not sure what we
        should do in this case.

        Adjust bootcheck tests for multiboot/coreboot/qemu to match real support.
        coreboot has ACPI while 2 others don't. *BSD need ACPI and have trouble
        without it. Don't even attempt to boot *BSD on multiboot or qemu targets.

        On coreboot boot all *BSD except 32-bit NetBSD which apparently does some
        early BIOS calls.

        configure: Add -fno-unwind-tables if supported.
        Unwind tables are useless for us bt consume space if present. Ensure that they
        are not.

        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
        with module loading.

        module-verifier: Check range-limited relative relocations.
        Check that they point to the same module, so will end up in the same
        chunk of memory.

        xen/relocator: Use local symbol to ensure that code is relocation-free.

        backtrace: Fix register call syntax

        Verify modules on build-time rather than failing in runtime.

        sparc64: Fix assembly to let compiler to fill in memory references.

        devmapper: check for valid device abstraction in get_grub_dev
        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
        detect DM abstraction, partitions on DM are skipped, we fall through to
        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.

        windows: correct LBA in generated EFI HDD media paths
        GRUB keeps partition offset and size in units of 512B sectors. Media paths
        are defined in terms of LBA which are presumed to match HDD sector size.

        This is probably cosmetic (EFI requires that partition is searched by GUID)
        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.

        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,

2015-10-14  Andrei Borzenkov  <arvidjaar@gmail.com>

        configure: force o32 ABI on MIPS
        GRUB code expects O32 or N32. N32 is less tested than O32, so we prefer to
        compile with O32. Some systems (e.g. GNU Guix) default to using newer
        n64 or n32 ABI. Try to find suitable options to force o32.

        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.

        efinet: handle get_status() on buggy firmware properly
        The EFI spec indicates that get_status() should return the address of the buffer
        we passed into transmit to indicate the the buffer was transmitted.  However we
        have boxes where the firmware returns some arbitrary address instead, which
        makes grub think that we've not sent anything.  So since we have the SNP stuff
        opened in exclusive mode just assume any non-NULL txbuf means that our transmit
        occurred properly.  This makes grub able to do its networking stuff properly on
        our broken firmware.  Thanks,

        exFAT doesn't handle "." and ".." correctly, convert it to fshelp to

        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 "..".

        may disable all receive filters on interface. Reinstall them after we
        opened protocol exclusively.

        Also follow UEFI specification recommendation and stop interfaces when
        closing them:

        Unexpected system errors, reboots and hangs can occur if an OS is loaded
        and the network devices are not Shutdown() and Stopped().

        Fix exit to EFI firmware
        The current code for EFI grub_exit() calls grub_efi_fini() before
        returning to firmware. In the case of ARM, this leaves a timer
        event running which could lead to a firmware crash. This patch
        changes this so that grub_machine_fini() is called with a NORETURN
        flag. This allows machine-specific shutdown to happen as well
        as the shutdown done by grub_efi_fini().

        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
        on top of Simple Management Protocol and does background polling. This
        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)
             Ctrl[BC] PciRoot(0x0)/Pci(0x3,0x0)/MAC(525400123456,0x1)/IPv6(0000:0000:0000:0000:0000:0000:0000:0000)

        Skip PXE created virtual devices when enumerating cards. Make sure to
        find real card when applying initial autoconfiguration during PXE boot,
        this information is associated with one of child devices.

        loader/linux: do not pad initrd with zeroes at the end
        Syslinux memdisk is using initrd image and needs to know uncompressed
        size in advance. For gzip uncompressed size is at the end of compressed
        stream. Grub padded each input file to 4 bytes at the end, which means
        syslinux got wrong size.

        Linux initramfs loader apparently does not care about trailing alignment.
        So change code to align beginning of each file instead which atomatically
        gives us the correct size for single file.

        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

        syslinux_parse: Fix the case of unknown localboot.
        Reported by: Jordan Uggla

        configure.ac: Fix the name of pciaccess header.

        Fix canonicalize_file_name clash.
        canonicalize_file_name clashed with gnulib function. Additionally
        it was declared in 2 places: emu/misc.h and util/misc.h. Added
        grub_ prefix and removed second declaration.

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.

        Don't continue to query block-size if disk doesn't have it.
        Stops poluting screen with a lot of "block-size: exception -21".

        gzio: Optimize by removing division.

        raid6: Optimize by removing division.

        dmraid_nvidia: Fix division by 0 and missing byte-swap.

        crypto: restrict cipher block size to power of 2.
        All current ciphers have blocks which are power of 2 and it's
        unlikely to change. Other block length would be tricky to handle anyway.
        This restriction allows avoiding extra divisions.

        jpeg: Optimise by replacing division with shifts.

        png: Optimize by avoiding divisions.

        minilzo: Skip parts tha we don't need.

2015-02-23  Vladimir Serbinenko  <phcoder@gmail.com>

        mips: Fix soft-float handling.
        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.

        acpi: Fix unused function warning.

        configure.ac: Add ia64-specific way to disable floats.

2015-02-22  Vladimir Serbinenko  <phcoder@gmail.com>

        Experimental support for clang for sparc64.
        Automatically discover command line options to make clang and
        gcc behave in same way.

        Tested with qemu.

2015-02-22  Vladimir Serbinenko  <phcoder@gmail.com>

        Discover which option provides soft-float on configure stage.
        Deals with clang needing other arguments to stop issuing floating
        instructions than gcc.

        mips: Switch to more portable .org
        Binary is unchanged.

        sparc64: Switch to more portable .org.
        Binaries are unchanged.

        kernel-8086: Switch to more portable .org.

        Relax requirements on asm for non-BIOS i386 platforms.
        These platforms don't have a hard limit on size of resulting code16
        code, so we don't care if assembly is bigger than necessarry.

        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.
        Binary is unchanged (verified).

        Test which flags make our asm compile.
        Previously we relied on assumption that clang always needs -no-integrated-as
        but it's not always true.

        INSTALL: clarify that clang support is experimental

        zfs/mzap_lookup: Fix argument types

        wildcard: Mark unused argument as such.

        ofdisk: Exclude floppies from scanning.
        It causes similar hang as CD on at least the qemu.

        configure: Add -msoft-float to CCASFLAGS
        Otherwise mismatch between API flags triggers linker failure

        mips/startup_raw: Use more portable .asciz

        Provide __aeabi_mem{cpy,set}
        Fixes ARM compilation

        div_test: Don't try to divide by zero

        INSTALL: Fix names of host flags to match actual behaviour

        Strip .MIPS.abiflags which causes compile failure

        ext2: Ignore INCOMPAT_MMP.
        It's not really incompatible as long as driver never writes to FS.

        ext2: Support META_BG.
        This fixes bug that system would become unbootable after ext*
        online resize if no resize_inode was created at ext* format time.

        diskfilter: fix double free of lv names for mdraid
        Avoid micro-optimization in grub_diskfilter_make_raid and make sure
        name and fullname are independent strings. This avoids need to special
        case it everywhere else.

        diskfilter: fix crash in validate_lv for mdraid arrays
        Commit 750f4bacd3262376ced3f837d8dc78f834ca233a put LV validation before
        actual vg assignment. Make grub_diskfilter_make_raid to assign ->vg as
        happens in other cases for consistency. Also clean up redundant code and add
        explicit NULL lv->vg check in validate_lv.

        Also fix segment validation in validate_lv; it became obvious when crash
        was fixed.

        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.

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

        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.

        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.

        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.
