From 4a066c7b27851227c0db963576b67b5af883ec3e Mon Sep 17 00:00:00 2001 From: Laszlo Ersek Date: Tue, 23 Jun 2015 14:54:00 +0000 Subject: CryptoPkg: OpensslLib: reintroduce EFIAPI for ERR_add_error_data() Git commit f93f78ea70 (SVN r17633), with subject "CryptoPkg: Update openssl patch file from 0.9.8zf to 1.0.2c", replaced the file CryptoPkg/Library/OpensslLib/EDKII_openssl-0.9.8zf.patch with CryptoPkg/Library/OpensslLib/EDKII_openssl-1.0.2c.patch In the process, two hunks were lost that used to add EFIAPI to the declaration of the variadic function ERR_add_error_data(). The VA_START() macro, from "MdePkg/Include/Base.h", expands to an EFIAPI-dependent implementation when !defined(__CC_ARM) && (!defined(__GNUC__) || defined(NO_BUILTIN_VA_FUNCS)) Under such circumstances, the va_start() macro invocation in ERR_add_error_data() -- which is translated to VA_START() by "CryptoPkg/Include/OpenSslSupport.h" -- results in EFIAPI-dependent code, but callers of the function pass the arguments incorrectly, because the declaration doesn't state EFIAPI. This leads to crashes when ERR_add_error_vdata(), called by ERR_add_error_data(), tries to access the arguments forwarded to it. Restore the missing hunk from before SVN r17633.
