Subject: [PATCH] 98integrity: support validating the IMA policy file signature
|
|
|
|
IMA validates file signatures based on the security.ima xattr. As of
|
|
Linux-4.7, instead of cat'ing the IMA policy into the securityfs policy,
|
|
the IMA policy pathname can be written, allowing the IMA policy file
|
|
signature to be validated.
|
|
|
|
This patch first attempts to write the pathname, but on failure falls
|
|
back to cat'ing the IMA policy contents .
