From 21d3946840fd62dc09e93986743915bcbac100b7 Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Sun, 30 Aug 2020 11:34:12 +0200 Subject: [PATCH] bootm: update image OS image size when decompressing In bootm_load_os() the OS image is decompressed. In later stages of the boot process we need the decompressed size of the image. Update images->os.image_len after decompression. Passing the correct size is necessary if we want to check loaded EFI binararies for file truncation by comparing the loaded size to the header field SizeOfImage.
