dm-verity can use Reed-Solomon forward error correction (FEC) data to transparently recover a limited number of corrupted blocks instead of only detecting them. This can be useful for mitigating error-prone storage. We generate this FEC data as an option, controlled by VERITY_FEC (default off, same behavior as before) and VERITY_FEC_ROOTS (number of Reed-Solomon roots, default 2). The FEC data is appended to the hash tree by default. If VERITY_IMAGE_FECDEV_SUFFIX is set, a separate file with the given suffix will be used. When enabled, the parameter file gains additional variables necessary for correct DM table generation. Recipes that do not set VERITY_FEC = "1" behave the same as before.
