This series improves the FWU (Firmware Update) subsystem's handling of boot failures by properly marking failed banks as invalid during rollback.
Patch 1 refactors fwu_state_machine_updates() to use an enum instead of a boolean, adding support for FWU_BANK_INVALID state. Patch 2 detects rollback at boot time (when boot_idx != active_idx) and marks the failed bank as invalid to prevent future boot attempts. Changes in v2: - Refactors fwu_state_machine_updates() to use enum as parameter instead of adding a new fwu_invalid_bank() helper. Kory Maincent (2): fwu: Pass bank state enum to fwu_state_machine_updates() fwu: Mark failed bank as invalid during rollback include/fwu.h | 22 ++++++++-------- lib/efi_loader/efi_capsule.c | 5 ++-- lib/fwu_updates/fwu.c | 6 +++++ lib/fwu_updates/fwu_v1.c | 16 ++++++------ lib/fwu_updates/fwu_v2.c | 50 +++++++++++++++--------------------- 5 files changed, 50 insertions(+), 49 deletions(-) -- 2.43.0
