    ima: extend the measurement list to include the file signature · bcbc9b0c
    Mimi Zohar 提交于
    This patch defines a new template called 'ima-sig', which includes
    the file signature in the template data, in addition to the file's
    digest and pathname.
    
    A template is composed of a set of fields.  Associated with each
    field is an initialization and display function.  This patch defines
    a new template field called 'sig', the initialization function
    ima_eventsig_init(), and the display function ima_show_template_sig().
    
    This patch modifies the .field_init() function definition to include
    the 'security.ima' extended attribute and length.
    
    Changelog:
    - remove unused code (Dmitry Kasatkin)
    - avoid calling ima_write_template_field_data() unnecesarily (Roberto Sassu)
    - rename DATA_FMT_SIG to DATA_FMT_HEX
    - cleanup ima_eventsig_init() based on Roberto's comments
