From 3dabf2d4a1a478fb00a232259e8043f075eb4d03 Mon Sep 17 00:00:00 2001 From: Remi Gacogne Date: Wed, 28 Jun 2023 15:23:35 +0200 Subject: [PATCH] Work around Red Hat 8 pooping the bed in OpenSSL's headers The openssl/kdf.h header on EL8 is invalid because someone backported a work-in-progress feature to an older OpenSSL branch and did not bother to backport the fixes that were added later. Red Hat declined to fix their mess and helpfully suggested we do the work instead in https://bugzilla.redhat.com/show_bug.cgi?id=2215856 --- m4/pdns_check_libcrypto.m4 | 10 +++++++++- 1 file changed, 9 insertions(+), 1 deletion(-) diff --git a/m4/pdns_check_libcrypto.m4 b/m4/pdns_check_libcrypto.m4 index 1fa4f23bda..4ca3c702ea 100644 --- a/m4/pdns_check_libcrypto.m4 +++ b/m4/pdns_check_libcrypto.m4 @@ -112,7 +112,15 @@ AC_DEFUN([PDNS_CHECK_LIBCRYPTO], [ [ AC_MSG_RESULT([yes]) AC_CHECK_FUNCS([RAND_bytes RAND_pseudo_bytes CRYPTO_memcmp OPENSSL_init_crypto EVP_MD_CTX_new EVP_MD_CTX_free RSA_get0_key]) - AC_CHECK_DECL(EVP_PKEY_CTX_set1_scrypt_salt, [AC_DEFINE([HAVE_EVP_PKEY_CTX_SET1_SCRYPT_SALT], [1], [Define to 1 if you have EVP_PKEY_CTX_set1_scrypt_salt])], [], [#include ]) + # you might be wondering why the stdarg.h and stddef.h includes, + # in which case please have a look at https://github.com/PowerDNS/pdns/issues/12926 + # and weep, yelling at Red Hat + AC_CHECK_DECL(EVP_PKEY_CTX_set1_scrypt_salt, + [AC_DEFINE([HAVE_EVP_PKEY_CTX_SET1_SCRYPT_SALT], [1], [Define to 1 if you have EVP_PKEY_CTX_set1_scrypt_salt])], + [], + [#include + #include + #include ]) $1 ], [ AC_MSG_RESULT([no]) -- 2.47.2
