With the introduction of the 'ima_template_fmt' kernel cmdline parameter,
a user can define a new template descriptor with custom format. However,
in this case, userspace tools will be unable to parse the measurements
list because the new template is unknown. For this reason, this patch
modifies the current IMA behavior to display in the list the template
format instead of the name (only if the length of the latter is zero)
so that a tool can extract needed information if it can handle listed
fields.
This patch also correctly displays the error log message in
ima_init_template() if the selected template cannot be initialized.
Changelog:
- v3:
- check the first byte of 'e->template_desc->name' instead of using
strlen() in ima_fs.c (suggested by Mimi Zohar)
- v2:
- print the template format in ima_init_template(), if the selected
template is custom (Roberto Sassu)
- v1:
- fixed patch description (Roberto Sassu, suggested by Mimi Zohar)
- set 'template_name' variable in ima_fs.c only once
(Roberto Sassu, suggested by Mimi Zohar)
