From 9eb111a7f7b897ba4ae19a68708e010a5c384260 Mon Sep 17 00:00:00 2001 From: Peter Jones Date: Fri, 19 Jun 2015 16:53:36 -0400 Subject: [PATCH 3/7] Build with -fshort-wchar so toggle passwords work right. This source tree uses: typedef wchar_t efi_char16_t; to define UEFI's UCS-2 character type. On many platforms, wchar_t is 32-bits by default. As a result, efichar_from_char winds up writing 4-byte characters instead of 2-byte characters. In the case where we hash the password in mokutil, this works fine, because the same datatype is used, and the values are the same. But for our feature toggles, where we store the raw data and shim is interpretting the character array, every other character winds up being L'\0', and verification fails. So always build with -fshort-wchar to ensure we get 2-byte character storage.
