From c522949a29d44d728517cc2579ed719747da3e5d Mon Sep 17 00:00:00 2001 From: Philippe Reynes Date: Wed, 29 Apr 2020 15:26:17 +0200 Subject: [PATCH] rsa: sig: fix config signature check for fit with padding The signature check on config node is broken on fit with padding. To compute the signature for config node, U-Boot compute the signature on all properties of requested node for this config, except for the property "data". But, when padding is used for binary in a fit, there isn't a property "data" but two properties: "data-offset" and "data-size". So to fix the check of signature, we also don't use the properties "data-offset" and "data-size" when checking the signature on config node.
