From 1cd9a787a2ee519665d914193e1022791397d621 Mon Sep 17 00:00:00 2001 From: "Daniel P. Berrange" Date: Fri, 23 Jun 2017 17:24:17 +0100 Subject: block: pass option prefix down to crypto layer While the crypto layer uses a fixed option name "key-secret", the upper block layer may have a prefix on the options. e.g. "encrypt.key-secret", in order to avoid clashes between crypto option names & other block option names. To ensure the crypto layer can report accurate error messages, we must tell it what option name prefix was used. Reviewed-by: Alberto Garcia Reviewed-by: Max Reitz Signed-off-by: Daniel P.
