From 54e7aac0562452e4fcab65ca5001d030eef2de15 Mon Sep 17 00:00:00 2001 From: Alexey Krasikov Date: Mon, 25 May 2020 14:19:12 +0300 Subject: crypto/linux_keyring: add 'secret_keyring' secret object. Add the ability for the secret object to obtain secret data from the Linux in-kernel key managment and retention facility, as an extra option to the existing ones: reading from a file or passing directly as a string. The secret is identified by the key serial number. The upper layers need to instantiate the key and make sure the QEMU process has access permissions to read it.
