Functions

  • zx_status_t CheckConfig (const fuchsia_hardware_block_verified::wire::Config & config, const block_info_t & blk)

    Checks that `config` specifies both a root hash and a block size, and that

    the block size matches the one observed in `blk`. Returns ZX_OK on success,

    ZX_ERR_INVALID_ARGS otherwise.

  • void GenerateSuperblock (const Geometry & info, uint8_t[32] root_hash, uint8_t * block_buf)

    Defined at line 15 of file ../../src/devices/block/drivers/block-verity/sealer.cc

  • IntegrityShape IntegrityShapeFor (uint32_t block_size, uint32_t hash_size, uint64_t data_block_count)

    Given a number of data blocks, a block size, and a hash output size, compute

    how many integrity blocks will be needed to provide integrity data for them,

    and how deep the hash tree would need to be to cover it.

  • extra_op_t * BlockToExtra (block_op_t * block, size_t op_size)

    Translates `block_op_t`s to `extra_op_t`s and vice versa.
