From acfb90911840c38a0beb9bcfe0065668244d2b4d Mon Sep 17 00:00:00 2001 From: Xiaoyu Lu Date: Wed, 29 May 2019 18:40:38 +0000 Subject: CryptoPkg/BaseCryptLib: Make HMAC_CTX size backward compatible Bugzilla: https://bugzilla.tianocore.org/show_bug.cgi?id=1089 OpenSSL internally redefines the size of HMAC_CTX at crypto/hmac/hmac_lcl.h(OpenSSL commit e0810e35). Ref: https://github.com/openssl/openssl/pull/4338 We should not use it directly and should remove relevant functions(Hmac*GetContextSize). Bugzilla: https://bugzilla.tianocore.org/show_bug.cgi?id=1792 But for compatiblility, temporarily change these definition of HMAC_*_CTX_SIZE.
