From 721da0396cfa0a4859cefb57e32cc79d19d80f54 Mon Sep 17 00:00:00 2001 From: Cédric Le Goater Date: Thu, 26 Oct 2023 09:06:34 +0200 Subject: util/uuid: Add UUID_STR_LEN definition MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit qemu_uuid_unparse() includes a trailing NUL when writing the uuid string and the buffer size should be UUID_FMT_LEN + 1 bytes. Add a define for this size and use it where required. Cc: Fam Zheng Reviewed-by: Philippe Mathieu-Daudé Reviewed-by: Juan Quintela Reviewed-by: "Denis V.
