Subject: [PATCH 0/3] ima-evm-utils: Implement function to only create IMA signature
Date: Tue, 20 Apr 2021 14:30:12 -0400	[thread overview]
Message-ID: <20210420183015.861644-1-stefanb@linux.ibm.com> (raw)

This series of patches implements imaevm_create_ima_signature, a function that
only creates an IMA v2 signature but does not write it into an xattr. This API
fullfills a requirement of rpm-ostree where a tool is being built to sign all
files from something similar to a tar byte stream, though where files are written
to temporary files for signing purpose but the signature itself should not be
written into the filesystem's xattr but simply returned via the API.
