Fixes CVE-2019-13917: http://www.exim.org/static/doc/security/CVE-2019-13917.txtd185889f47added new code to "Prebuild the data structure for builtin macros". This function needs a host-built binary called macro_predef, it depends on host-berkeleydb, host-pcre and optionally on host-openssl. With an openssl-enabled exim the host build of macro_predef will fail if host-openssl is missing: /usr/bin/gcc -DMACRO_PREDEF macro_predef.c In file included from hash.h:14, from exim.h:485, from macro_predef.c:11: sha_ver.h:37:12: fatal error: openssl/ssl.h: No such file or directory because macro_predef also has the an optional dependency on openssl: https://github.com/Exim/exim/blob/exim-4.92%2Bfixes/src/src/macro_predef.c#L130 Removed patches applied upstream: 0004:98913c8ea20005:cf3cd306060007:7ea1237c78 (diff-58af16fe62ea674adf1730edc078d175R6243)Added patch to fix uClibc build. Added license hash, switched _SITE to https. Signed-off-by: Bernd Kuhls <bernd.kuhls@t-online.de> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com>
