It does this since the data to verify has to +be passed as a single chunk to modules that use the verifiers framework. + +If the initrd image size is big there may not be enough memory in the heap +to allocate two buffers of that size. This causes an allocation failure in +the verifiers framework and leads to the initrd not being read. + +To prevent these allocation failures, let's reduce the maximum size of the +bounce buffer used in the EFI loader. Since the data read can be copied to +the actual initrd address in multilple chunks. + +Resolves: rhbz#1838633 + +Signed-off-by: Javier Martinez Canillas +(cherry picked from commit 1c0d2ebdddf69962395f0fa4578446654512f3c4) +--- + grub-core/loader/i386/efi/linux.c | 2 +- + 1 file changed, 1 insertion(+), 1 deletion(-) + +diff --git a/grub-core/loader/i386/efi/linux.c b/grub-core/loader/i386/efi/linux.c +index e9d2c85b3..a043df891 100644 +--- a/grub-core/loader/i386/efi/linux.c ++++ b/grub-core/loader/i386/efi/linux.c +@@ -146,7 +146,7 @@ grub_linuxefi_unload (void) + return GRUB_ERR_NONE; + } + +-#define BOUNCE_BUFFER_MAX 0x10000000ull ++#define BOUNCE_BUFFER_MAX 0x1000000ull + + static grub_ssize_t + read(grub_file_t file, grub_uint8_t *bufp, grub_size_t len) diff --git a/SOURCES/grub.patches b/SOURCES/grub.patches index 7bd9e4a..9cd50b1 100644 --- a/SOURCES/grub.patches +++ b/SOURCES/grub.patches @@ -489,6 +489,12 @@ Patch0488: 0488-powerpc-fix-prefix-signed-grub-special-case-for-Powe.patch Patch0489: 0489-grub-mkconfig-restore-umask-for-grub.cfg.patch Patch0490: 0490-efinet-Add-DHCP-proxy-support.patch Patch0491: 0491-at_keyboard-Fix-unreliable-key-presses.patch -Patch0492: 0492-search-fixed-bug-stopping-iteration-when-no-floppy-i.patch +Patch0492: 0492-commands-search-Fix-bug-stopping-iteration-when-no-f.patch Patch0493: 0493-search-new-efidisk-only-option-on-EFI-systems.patch Patch0494: 0494-efi-new-connectefi-command.patch +Patch0495: 0495-Try-to-pick-better-locations-for-kernel-and-initrd.patch +Patch0496: 0496-x86-efi-Use-bounce-buffers-for-reading-to-addresses-.patch +Patch0497: 0497-x86-efi-Re-arrange-grub_cmd_linux-a-little-bit.patch +Patch0498: 0498-x86-efi-Make-our-own-allocator-for-kernel-stuff.patch +Patch0499: 0499-x86-efi-Allow-initrd-params-cmdline-allocations-abov.patch +Patch0500: 0500-x86-efi-Reduce-maximum-bounce-buffer-size-to-16-MiB.patch diff --git a/SPECS/grub2.spec b/SPECS/grub2.spec index 063db0f..f3deb78 100644 --- a/SPECS/grub2.spec +++ b/SPECS/grub2.spec @@ -7,7 +7,7 @@ Name: grub2 Epoch: 1 Version: 2.02 -Release: 120%{?dist} +Release: 122%{?dist} Summary: Bootloader with support for Linux, Multiboot and more Group: System Environment/Base License: GPLv3+ @@ -510,11 +510,19 @@ fi %endif %changelog -* Fri Feb 28 2022 Robbie Harwood - 2.06-120 +* Wed Mar 09 2022 Robbie Harwood - 2.06-122 +- Fix initialization on efidisk patch +- Resolves: #2061252 + +* Tue Mar 08 2022 Robbie Harwood - 2.06-121 +- Backport support for loading initrd above 4GB +- Resolves: #2048433 + +* Mon Feb 28 2022 Robbie Harwood - 2.06-120 - Bump signing - Resolves: #2032294 -* Fri Feb 28 2022 Robbie Harwood - 2.06-119 +* Mon Feb 28 2022 Robbie Harwood - 2.06-119 - Enable connectefi module - Resolves: #2032294
