2018-08-24libavb: Handle wrong hashtree_error_mode in avb_append_options()Ievgen Maliarenko1-0/+3
Exit with AVB_SLOT_VERIFY_RESULT_ERROR_INVALID_ARGUMENT when hashtree_error_mode value passed to avb_append_options() is unknown (not from AvbHashtreeErrorMode enum). Otherwise, default value is not handled in the switch(hashtree_error_mode), which causes below compile warning: lib/libavb/avb_cmdline.c: In function ‘avb_append_options’: lib/libavb/avb_cmdline.c:354:13: warning: ‘dm_verity_mode’ may be used uninitialized in this function [-Wmaybe-uninitialized] new_ret = avb_replace( ~~~~~~~~^~~~~~~~~~~~~~ slot_data->cmdline, "$(ANDROID_VERITY_MODE)", dm_verity_mode); ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ lib/libavb/avb_cmdline.c:363:8: warning: ‘verity_mode’ may be used uninitialized in this function [-Wmaybe-uninitialized] if (!cmdline_append_option( ^~~~~~~~~~~~~~~~~~~~~~ slot_data, "androidboot.veritymode", verity_mode)) { Signed-off-by: Ievgen Maliarenko <ievgen.maliarenko@globallogic.com> Signed-off-by: Eugeniu Rosca <erosca@de.adit-jv.com> Reviewed-by: Igor Opaniuk <igor.opaniuk@linaro.org>

2018-06-18avb2.0: add Android Verified Boot 2.0 libraryIgor Opaniuk35-0/+6698
Add libavb lib (3rd party library from AOSP), that implements support of AVB 2.0. This library is used for integrity checking of Android partitions on eMMC. libavb was added as it is and minimal changes were introduced to reduce maintenance cost, because it will be deviated from AOSP upstream in the future. Changes: - license headers changed to conform SPDX-style - avb_crc32.c dropped - updates in avb_sysdeps_posix.c/avb_sysdeps.h For additional details check [1] AVB 2.0 README.
