boot/grub: fix grub-mkimage with binutils >= 2.31

2018-12-13T20:37:08+00:00

While using pc_x86_64_efi_defconfig with a bleeding-edge x86_64 toolchain based on binutils 2.31, the grub-mkimage command return this error: grub-mkimage: error: relocation 0x4 is not implemented yet. Backport an upstream patch [1] as suggested on openembedded mailing list [2].

grub2: add usage notes for grub2 arm and aarch64

2018-11-26T21:11:07+00:00

Add notes to test grub2 running on ARM using qemu. The arm section describes how to run it using u-boot and aarch64 shows how to do it using efi, which is similar to what has to be done for x86_64. The source for OVMF builds is also changed to https://www.kraxel.org/repos/jenkins/edk2/ which is the source for nightly builds (as rpms but which can be extracted in any distribution), as the sourceforge link provided only very old builds.

boot/grub2: enable support for arm and aarch64 targets

2018-11-26T20:08:13+00:00

This commit enables the arm-uboot, arm-efi and aarch64-efi grub2 platforms in Buildroot. With the uboot platform, the grub2 image gets built as a u-boot image and is loaded from u-boot through a regular "bootm". The only requirement from the u-boot side in order to allow this is that u-boot is built with CONFIG_API enabled. CONFIG_API seems to not be enabled by default in most in-tree configurations, however, it seems to be available for quite some time now. So it might be possible to use this even on older u-boot versions. This is available only for arm (32-bit). With the efi platform, grub2 gets built as an EFI executable. This allows EFI firmware to find and load it similarly as it can be done for x86_64. Also, since u-boot v2016.05, u-boot is able to load and boot an EFI executable, so the uboot efi platform can also be used from u-boot in recent versions. This has been enabled (mostly) by default for ARM u-boot. efi platform is available for both arm and aarch64.

boot/grub2: add option to install tools

2018-11-26T19:59:33+00:00

Add an option to install grub2 support tools to the target. In the context of Buildroot, some useful target tools provided are grub2-editenv, grub2-reboot, which provide means to manage the grub2, environment, boot order, and others. Signed-off-by: Erico Nunes Signed-off-by: Thomas Petazzoni

boot/grub2: separate target and host builds

2018-11-26T19:58:37+00:00

grub2 requires the host grub2-mkimage tool to build some of its target images. The current way of building this tool in the grub2 package is to perform a simultaneous host-tools/target-bootloader build during the grub2 build step. This method makes the recipe complex to understand, and proved to be a complication during the work to enable grub2 support for architectures other than x86. This patch tries to do a better separation between the build of grub2 host tools and target boot loader image, as a partial step to enable grub2 to build for other architectures.

grub2: force -fno-stack-protector in CPPFLAGS

2018-04-19T21:26:06+00:00

In commit 2a27294e9ade6130a12ced9a1f152c51431a870e ("grub2: force -fno-stack-protector in CFLAGS"), a fix was made to the grub2 package to make it build properly even when SSP support is enabled. However, commit 20a4583ebf7fe97ea22a1ea11621dd44a8114ca5 ("security hardening: add RELFO, FORTIFY options") reworked how SSP options are passed, and they are now passed in CPPFLAGS instead of CFLAGS, making the fix introduced by 2a27294e9ade6130a12ced9a1f152c51431a870e no longer operating. This commit will force no-stack-protector in CPPFLAGS instead of CFLAGS. Fixes bug #10961. Signed-off-by: Tarek El-Sherbiny Signed-off-by: Thomas Petazzoni

grub2: force -fno-stack-protector in CFLAGS

2017-08-30T20:09:21+00:00

grub2 fails to configure when BR2_SSP_ALL is enabled, with the following configure error: checking whether -fno-asynchronous-unwind-tables works... yes checking whether -fno-unwind-tables works... yes checking for target linking format... unknown configure: error: no suitable link format found This can be worked around by enforcing -fno-stack-protector in the package CFLAGS in a way that overrides the SSP flag, as is already done for the valgrind package. Fixes bug #10261. Signed-off-by: Erico Nunes Reported-by: Dr I J Ormshaw Signed-off-by: Thomas Petazzoni

grub2: move usage notes to package readme.txt

2017-07-16T13:25:27+00:00

As discussed in the mailing list, grub2 usage notes were growing too big for a Config.in documentation, and so it was agreed that a readme.txt in the package directory is a better place to put them. This commit simply moves the documentation as-is to preserve the original contents as they were in Config.in which can be worked on in further commits.

grub2: bump up version

2017-07-16T12:55:33+00:00

After many years since the last release and a long time with grub 2.02 in beta, there is finally a release and it brings many bug fixes and interesting features such as support for ARM. Patch boot/grub2/0001-remove-gets.patch doesn't seem to be required anymore as grub-core/gnulib/stdio.in.h has changed significantly since "053cfcd Import new gnulib." and has another treatment for gets. Patch boot/grub2/0002-grub-core-gettext-gettext.c-main_context-secondary_c.patch was a backport which is present after the bump and therefore is also no longer necessary. Since we're adding a Config.in comment, we also introduce a BR2_TARGET_GRUB2_ARCH_SUPPORTS hidden boolean, in order to avoid repeating the architecture dependencies.

grub2: install in $(HOST_DIR) instead of $(HOST_DIR)/usr

2017-07-05T14:06:47+00:00

grub2 builds for the target but installs with DESTDIR=$(HOST_DIR). Since we set prefix to /usr in TARGET_CONF_OPTS, this results in installing things in $(HOST_DIR)/usr. To make sure we don't install in $(HOST_DIR)/usr, override --prefix and --exec-prefix. Signed-off-by: Arnout Vandecappelle (Essensium/Mind) Signed-off-by: Thomas Petazzoni
