[U-Boot] [PATCH] fs: btrfs: Do not fail when all root_backups are empty
by Yevgeny Popovych 19 Jun '18

19 Jun '18

This is the case when reading freshly created filesystem. The error message is like the following: btrfs_read_superblock: No valid root_backup found! Since the data from super_roots/root_backups is not actually used - decided to rework btrfs_newest_root_backup() into btrfs_check_super_roots() that will only check if super_roots array is valid and correctly handle empty scenario. As a result: * btrfs_read_superblock() now only checks if super_roots array is valid; the case when it is empty is considered OK. * removed root_backup pointer from btrfs_info, which would be NULL in case of empty super_roots. * btrfs_read_superblock() verifies number of devices from the superblock itself, not newest root_backup.

[U-Boot] [PATCH v2 0/8] Initial integration of AVB2.0
by Igor Opaniuk 19 Jun '18

19 Jun '18

This series of patches introduces support of Android Verified Boot 2.0, which provides integrity checking of Android partitions on MMC. It integrates libavb into the U-boot, provides implementation of AvbOps, subset of `avb` commands to run verification chain (and for debugging purposes), and it enables AVB2.0 verification on AM57xx HS SoC by default. Currently, there is still no support for verification of A/B boot slots and no rollback protection (for storing rollback indexes there are plans to use eMMC RPMB) Libavb will be deviated from AOSP upstream in the future, that's why minimal amount of changes were introduced into the lib sources, so checkpatch may fail. For additional details check [1] AVB 2.0 README and doc/README.avb2, which is a part of this patchset. [1] https://android.googlesource.com/platform/external/avb/+/master/README.md Changes for v2: - Updated libavb from the AOSP upstream - Removed libavb_ab is it's marked as deprecated - Added default n to Kconfigs for this feature (both for CONFIG_LIBAVB and CONFIG_CMD_AVB) - Minor fixes in avb_find_dm_args - Replaced "reinvented the wheel" str macro with existing __stringify() - Updated documentation - Updated avb_slot_verify invocation, supplying with new AvbHashtreeErrorMode param - Fixed array boundary exceeded error when handling bootargs in avb_find_dm_args Igor Opaniuk (8): avb2.0: add Android Verified Boot 2.0 library avb2.0: integrate avb 2.0 into the build system avb2.0: implement AVB ops cmd: avb2.0: avb command for performing verification avb2.0: add boot states and dm-verity support am57xx_hs: avb2.0: add support of AVB 2.0 test/py: avb2.0: add tests for avb commands doc: avb2.0: add README about AVB2.0 integration cmd/Kconfig | 16 + cmd/Makefile | 3 + cmd/avb.c | 372 ++++++++ common/Makefile | 2 + common/avb_verify.c | 741 +++++++++++++++ doc/README.avb2 | 97 ++ include/avb_verify.h | 96 ++ include/configs/am57xx_evm.h | 11 + include/environment/ti/boot.h | 15 + lib/Kconfig | 14 + lib/Makefile | 1 + lib/libavb/Makefile | 15 + lib/libavb/avb_chain_partition_descriptor.c | 46 + lib/libavb/avb_chain_partition_descriptor.h | 54 ++ lib/libavb/avb_cmdline.c | 422 +++++++++ lib/libavb/avb_cmdline.h | 72 ++ lib/libavb/avb_crypto.c | 354 +++++++ lib/libavb/avb_crypto.h | 156 +++ lib/libavb/avb_descriptor.c | 142 +++ lib/libavb/avb_descriptor.h | 113 +++ lib/libavb/avb_footer.c | 36 + lib/libavb/avb_footer.h | 68 ++ lib/libavb/avb_hash_descriptor.c | 44 + lib/libavb/avb_hash_descriptor.h | 70 ++ lib/libavb/avb_hashtree_descriptor.c | 52 + lib/libavb/avb_hashtree_descriptor.h | 80 ++ lib/libavb/avb_kernel_cmdline_descriptor.c | 40 + lib/libavb/avb_kernel_cmdline_descriptor.h | 63 ++ lib/libavb/avb_ops.h | 293 ++++++ lib/libavb/avb_property_descriptor.c | 167 ++++ lib/libavb/avb_property_descriptor.h | 89 ++ lib/libavb/avb_rsa.c | 276 ++++++ lib/libavb/avb_rsa.h | 55 ++ lib/libavb/avb_sha.h | 72 ++ lib/libavb/avb_sha256.c | 364 +++++++ lib/libavb/avb_sha512.c | 362 +++++++ lib/libavb/avb_slot_verify.c | 1367 +++++++++++++++++++++++++++ lib/libavb/avb_slot_verify.h | 341 +++++++ lib/libavb/avb_sysdeps.h | 101 ++ lib/libavb/avb_sysdeps_posix.c | 63 ++ lib/libavb/avb_util.c | 412 ++++++++ lib/libavb/avb_util.h | 269 ++++++ lib/libavb/avb_vbmeta_image.c | 290 ++++++ lib/libavb/avb_vbmeta_image.h | 276 ++++++ lib/libavb/avb_version.c | 16 + lib/libavb/avb_version.h | 41 + lib/libavb/libavb.h | 32 + test/py/tests/test_avb.py | 111 +++ 48 files changed, 8192 insertions(+) create mode 100644 cmd/avb.c create mode 100644 common/avb_verify.c create mode 100644 doc/README.avb2 create mode 100644 include/avb_verify.h create mode 100644 lib/libavb/Makefile create mode 100644 lib/libavb/avb_chain_partition_descriptor.c create mode 100644 lib/libavb/avb_chain_partition_descriptor.h create mode 100644 lib/libavb/avb_cmdline.c create mode 100644 lib/libavb/avb_cmdline.h create mode 100644 lib/libavb/avb_crypto.c create mode 100644 lib/libavb/avb_crypto.h create mode 100644 lib/libavb/avb_descriptor.c create mode 100644 lib/libavb/avb_descriptor.h create mode 100644 lib/libavb/avb_footer.c create mode 100644 lib/libavb/avb_footer.h create mode 100644 lib/libavb/avb_hash_descriptor.c create mode 100644 lib/libavb/avb_hash_descriptor.h create mode 100644 lib/libavb/avb_hashtree_descriptor.c create mode 100644 lib/libavb/avb_hashtree_descriptor.h create mode 100644 lib/libavb/avb_kernel_cmdline_descriptor.c create mode 100644 lib/libavb/avb_kernel_cmdline_descriptor.h create mode 100644 lib/libavb/avb_ops.h create mode 100644 lib/libavb/avb_property_descriptor.c create mode 100644 lib/libavb/avb_property_descriptor.h create mode 100644 lib/libavb/avb_rsa.c create mode 100644 lib/libavb/avb_rsa.h create mode 100644 lib/libavb/avb_sha.h create mode 100644 lib/libavb/avb_sha256.c create mode 100644 lib/libavb/avb_sha512.c create mode 100644 lib/libavb/avb_slot_verify.c create mode 100644 lib/libavb/avb_slot_verify.h create mode 100644 lib/libavb/avb_sysdeps.h create mode 100644 lib/libavb/avb_sysdeps_posix.c create mode 100644 lib/libavb/avb_util.c create mode 100644 lib/libavb/avb_util.h create mode 100644 lib/libavb/avb_vbmeta_image.c create mode 100644 lib/libavb/avb_vbmeta_image.h create mode 100644 lib/libavb/avb_version.c create mode 100644 lib/libavb/avb_version.h create mode 100644 lib/libavb/libavb.h create mode 100644 test/py/tests/test_avb.py -- 2.7.4

[U-Boot] Load from ext4 can fail or get incoherent data because of the journaling
by Jean-Christian de Rivaz 19 Jun '18

19 Jun '18

Hi all, Some system really need ext4 journal_data option to avoid any inconsistency on his filesystem in case of unexpected power failure. While journal_data greatly improved the reliability of the system from the Linux kernel point of view, to my surprise this has increase the failure rate of U-Boot. Sometime a file is not found by U-Boot (notably the armbianEnv.txt file in my case) or his content can even be from an other file ! The most frequently message in the later case is: ** File not found /boot/dtb/overlay/-fixup.scr ** Because the ${overlay_prefix} variable was not imported from the corrupted read of the armbianEnv.txt file. The file is read correctly by the Linux kernel. I have found that others U-Boot users have spot this message, but to my knowledge this has not be linked to the failure of U-Boot to use the ext4 journal. I think that the problem can affect any ext4 files loaded by U-Boot that have part in the ext4 journal, making a serious issue on the U-Boot reliability if I am right. From my understanding the ext4_journal.c code into U-Boot only handle write transactions to the ext4 journal and is not used while reading a file. I there someone with some experience in that field that can assert / reject / help about my observation ? Best regards Jean-Christian de Rivaz

[U-Boot] [PATCH v4 0/5] efi_loader: ARM: add support for ARMV7_NONSEC=y
by Mark Kettenis 19 Jun '18

19 Jun '18

This series makes it possible to run EFI applications in non-secure mode. It allows me to run OpenBSD on the Technexion PICO-PI-IMX7 and Banana Pi boards using the PSCI implementation provided by U-Boot. The second version avoids using r3 to pass the original stack pointer. For some reason that register gets clobbered on the Banana Pi. Instead this version just migrates SP_svc to SP_hyp. The third version avoids saving r3 on the stack and fixes an include guard as suggested by Alexander Graf. This fourth version enables ARMV7_LPAE if HYP mode is supported sych that we enable the MMU and caches in HYP mode. It also makes sure we don't attempt to enter non-secure mode twice if we execute a 2nd EFI payload. Mark Kettenis (5): ARM: HYP/non-sec: migrate stack efi_loader: ARM: run EFI payloads non-secure efi_loader: ARM: don't attempt to enter non-secure mode twice ARM: HYP/non-sec: enable ARMV7_LPAE if HYP mode is supported Revert "efi_loader: no support for ARMV7_NONSEC=y" arch/arm/cpu/armv7/Kconfig | 2 +- arch/arm/cpu/armv7/nonsec_virt.S | 2 ++ cmd/bootefi.c | 36 ++++++++++++++++++++++++++++++++++++ doc/README.uefi | 2 -- lib/efi_loader/Kconfig | 2 -- 5 files changed, 39 insertions(+), 5 deletions(-) -- 2.16.2
