    ima: switch to new template management mechanism · a71dc65d
    Roberto Sassu authored
    This patch performs the switch to the new template mechanism by modifying
    the functions ima_alloc_init_template(), ima_measurements_show() and
    ima_ascii_measurements_show(). The old function ima_template_show() was
    removed as it is no longer needed. Also, if the template descriptor used
    to generate a measurement entry is not 'ima', the whole length of field
    data stored for an entry is provided before the data itself through the
    binary_runtime_measurement interface.
    
    Changelog:
    - unnecessary to use strncmp() (Mimi Zohar)
    - create new variable 'field' in ima_alloc_init_template() (Roberto Sassu)
    - use GFP_NOFS flag in ima_alloc_init_template() (Roberto Sassu)
    - new variable 'num_fields' in ima_store_template() (Roberto Sassu,
      proposed by Mimi Zohar)
    - rename ima_calc_buffer_hash/template_hash() to ima_calc_field_array_hash(),
      something more generic (Mimi, requested by Dmitry)
    - sparse error fix - Fengguang Wu
    - fix lindent warnings
    - always include the field length in the template data length
    - include the template field length variable size in the template data length
    - include both the template field data and field length in the template digest
      calculation. Simplifies verifying the template digest. (Mimi)
