Changelog

grub2 (2.02+dfsg1-5ubuntu1) cosmic; urgency=medium

  [ Mathieu Trudel-Lapierre]
  * Merge against Debian unstable; remaining changes:
    - debian/control: Update Vcs fields for code location on Ubuntu.
    - debian/control: Breaks shim (<< 13).
    - Secure Boot support: use newer patchset from rhboot repo:
      - many linuxefi_* patches added and modified
      - dropped debian/patches/linuxefi_require_shim.patch
      - renamed: debian/patches/no_insmod_on_sb.patch ->
        debian/patches/linuxefi_no_insmod_on_sb.patch
    - debian/patches/install_signed.patch, grub-install-extra-removable.patch:
      - Make sure if we install shim; it should also be exported as the default
        bootloader to install later to a removable path, if we do.
      - Rework grub-install-extra-removable.patch to reverse its logic: in the
        default case, install the bootloader to /EFI/BOOT, unless we're trying
        to install on a removable device, or explicitly telling grub *not* to
        do it.
      - Move installing fb$arch.efi to --no-extra-removable; as we don't want
        fallback to be installed unless we're also installing to /EFI/BOOT.
        (LP: #1684341)
      - Install a BOOT.CSV for fallback to use.
      - Make sure postinst and templates know about the replacement of
        --force-extra-removable with --no-extra-removable.
    - debian/patches/add-an-auto-nvram-option-to-grub-install.patch: Add the
      --auto-nvram option to grub-install for auto-detecting NVRAM availability
      before attempting NVRAM updates.
    - debian/build-efi-images: provide a new grub EFI image which enforces that
      loaded kernels are signed for Secure Boot: build gsb$arch.efi; which is
      the same as grub$arch.efi minus the 'linux' module. Without fallback to
      'linux' for unsigned loading, this makes it effectively enforce having a
      signed kernel. (LP: #1401532)
    - Verify that the current and newer kernels are signed when grub is
      updated, to make sure people do not accidentally shutdown without a
      signed kernel.
    - debian/default/grub: replace GRUB_HIDDEN_* variables with the less
      confusing GRUB_TIMEOUT_STYLE=hidden. (LP: #1258597)
    - debian/patches/support_initrd-less_boot.patch: Added knobs to allow
      non-initrd boot config. (LP: #1640878)
    - Disable os-prober for ppc64el on the PowerNV platform, to reduce the
      number of entries/clutter from other OSes in Petitboot (LP: #1447500)
    - debian/patches/shorter_version_info.patch: Only show the upstream version
      in menu and console, and hide the package one in a package_version
      variable. (LP: #1723434)
    - debian/patches/skip_text_gfxpayload_where_not_supported.patch: Skip the
      'text' payload if it's not supported but present in gfxpayload, such as
      on EFI systems. (LP: #1711452)
    - debian/patches/bufio_sensible_block_sizes.patch: Don't use arbitrary file
      fizes as block sizes in bufio: this avoids potentially seeking back in
      the files unnecessarily, which may require re-open files that cannot be
      seeked into, such as via TFTP. (LP: #1743249)
    * util/grub-install.c: Drop extra handling for x.efi.signed files for mok
      and fallback binaries: shim now installs them without the .signed
      extension. (LP: #1708245)
    - debian/patches/dont-fail-efi-warnings.patch: handle linuxefi patches and
      the casting they do on some architectures: we don't want to fail build
      because of some of the warnings that can show up since we otherwise build
      with -Werror.
  * debian/rules: shuffle files around for now to keep putting build artefacts
    for signing at the same location as they were expected by Launchpad.

  [ Julian Andres Klode ]
  * debian/patches/ofnet-init-structs-in-bootpath-parser.patch: initialize
    structs in bootpath parser. Fixes netboot issues on ppc64el. (LP: #1785859)

Binary packages built by this source

grub-common: GRand Unified Bootloader (common files)

 This package contains common files shared by the distinct flavours of GRUB.
 It is shared between GRUB Legacy and GRUB 2, although a number of files
 specific to GRUB 2 are here as long as they do not break GRUB Legacy.

grub-common-dbgsym: debug symbols for grub-common
grub-coreboot: GRand Unified Bootloader, version 2 (Coreboot version)

 GRUB is a portable, powerful bootloader. This version of GRUB is based on a
 cleaner design than its predecessors, and provides the following new features:
 .
  - Scripting in grub.cfg using BASH-like syntax.
  - Support for modern partition maps such as GPT.
  - Modular generation of grub.cfg via update-grub. Packages providing GRUB
    add-ons can plug in their own script rules and trigger updates by invoking
    update-grub.
 .
 This package contains a version of GRUB that has been built for use with
 platforms running the Coreboot firmware.

 .
 This package contains a version of GRUB that has been built for use with
 the Xen hypervisor (i.e. PV-GRUB). It will not automatically install GRUB
 as the active boot loader, nor will it automatically update grub.cfg on
 upgrade, so most people should install grub-xen instead.

grub-xen-dbg: GRand Unified Bootloader, version 2 (Xen debug files)

 This package contains debugging files for grub-xen-bin. You only need
 these if you are trying to debug GRUB using its GDB stub.

grub-xen-host: GRand Unified Bootloader, version 2 (Xen host version)

 GRUB is a portable, powerful bootloader. This version of GRUB is based on a
 cleaner design than its predecessors, and provides the following new features:
 .
  - Scripting in grub.cfg using BASH-like syntax.
  - Support for modern partition maps such as GPT.
  - Modular generation of grub.cfg via update-grub. Packages providing GRUB
    add-ons can plug in their own script rules and trigger updates by invoking
    update-grub.
 .
 This package arranges for GRUB binary images which can be used to boot a Xen
 guest (i.e. PV-GRUB) to be present in the control domain filesystem.

grub2: GRand Unified Bootloader, version 2 (dummy package)

 This is a dummy transitional package to handle GRUB 2 upgrades. It can be
 safely removed.

grub2-common: GRand Unified Bootloader (common files for version 2)

 This package contains common files shared by the distinct flavours of GRUB.
 The files in this package are specific to GRUB 2, and would break GRUB
 Legacy if installed on the same system.
