ima: define template fields library and new helpers
This patch defines a library containing two initial template fields, inode digest (d) and file name (n), the 'ima' template descriptor, whose format is 'd|n', and two helper functions, ima_write_template_field_data() and ima_show_template_field_data(). Changelog: - replace ima_eventname_init() parameter NULL checking with BUG_ON. (suggested by Mimi) - include "new template fields for inode digest (d) and file name (n)" definitions to fix a compiler warning. - Mimi - unnecessary to prefix static function names with 'ima_'. remove prefix to resolve Lindent formatting changes. - Mimi - abbreviated/removed inline comments - Mimi - always send the template field length - Mimi Signed-off-by: Roberto Sassu <roberto.sassu@polito.it> Signed-off-by: Mimi Zohar <zohar@linux.vnet.ibm.com>
