Subject: [PATCH v4 01/10] include: pe.h: remove message[] from mz header definition
Date: Mon, 2 Oct 2017 15:14:22 +0900 [thread overview]
Message-ID: <20171002061431.11117-2-takahiro.akashi@linaro.org> (raw)
In-Reply-To: <20171002061431.11117-1-takahiro.akashi@linaro.org>
message[] field won't be part of the definition of mz header.
This change is crucial for enabling kexec_file_load on arm64 because
arm64's "Image" binary, as in PE format, doesn't have any data for it and
accordingly the following check in pefile_parse_binary() will fail:
chkaddr(cursor, mz->peaddr, sizeof(*pe));
