Subject: [PATCH] Fix sign_hash not observing the hashalgo argument
|
||||
|
||||
This fixes sign_hash not using the correct algorithm for creating the
|
||||
signature, by ensuring it uses the passed in variable value.

||||

The Trusted Computing Group(TCG) run-time Integrity Measurement Architecture
|

(IMA) maintains a list of hash values of executables and other sensitive
|
||||
system files, as they are read or executed. These are stored in the file
|

systems extended attributes. The Extended Verification Module (EVM) prevents
|
||||
unauthorized changes to these extended attributes on the file system.
|

ima-evm-utils is used to prepare the file system for these extended attributes.

When there are >reinstall_threshold (=20 by default) packages in the RPM

DB missing IMA signatures, reinstalling the packages to add IMA

signatures to the packages. By default, IMA sigatures will be obtained

from the RPM DB. However the RPM DB may not have the signatures. Dectect

this case by checking if there are >reinstall_threshold package missing

(IMA) maintains a list of hash values of executables and other sensitive

system files, as they are read or executed. These are stored in the file

systems extended attributes. The Extended Verification Module (EVM) prevents

unauthorized changes to these extended attributes on the file system.
