From 8e266b9eeffa3c1fc4dca0081c0553f8c2a488c0 Mon Sep 17 00:00:00 2001 From: Dave Reisner Date: Wed, 13 Feb 2019 10:27:51 -0500 Subject: Link against libcrypto, not all of openssl In the previous build setup, libkmod.so would link to not just libcrypto.so, but also libssl.so: $ readelf -d /lib/libkmod.so | grep NEEDED 0x0000000000000001 (NEEDED) Shared library: [liblzma.so.5] 0x0000000000000001 (NEEDED) Shared library: [libz.so.1] 0x0000000000000001 (NEEDED) Shared library: [libssl.so.1.1] 0x0000000000000001 (NEEDED) Shared library: [libcrypto.so.1.1] 0x0000000000000001 (NEEDED) Shared library: [libc.so.6] We don't need any symbols from libssl, though. This patch ensures that we pass 'libcrypto' to pkgconfig rather than 'openssl', getting only the library that we need: $ readelf -d ./libkmod/.libs/libkmod.so.2.3.4 | grep NEEDED 0x0000000000000001 (NEEDED) Shared library: [liblzma.so.5] 0x0000000000000001 (NEEDED) Shared library: [libz.so.1] 0x0000000000000001 (NEEDED) Shared library: [libcrypto.so.1.1] 0x0000000000000001 (NEEDED) Shared library: [libc.so.6] --- Makefile.am | 6 +++--- configure.ac | 4 ++-- 2 files changed, 5 insertions(+), 5 deletions(-) diff --git a/Makefile.am b/Makefile.am index ddb25f0..758f4f0 100644 --- a/Makefile.am +++ b/Makefile.am @@ -35,8 +35,8 @@ SED_PROCESS = \ -e 's,@liblzma_LIBS\@,${liblzma_LIBS},g' \ -e 's,@zlib_CFLAGS\@,${zlib_CFLAGS},g' \ -e 's,@zlib_LIBS\@,${zlib_LIBS},g' \ - -e 's,@openssl_CFLAGS\@,${openssl_CFLAGS},g' \ - -e 's,@openssl_LIBS\@,${openssl_LIBS},g' \ + -e 's,@libcrypto_CFLAGS\@,${libcrypto_CFLAGS},g' \ + -e 's,@libcrypto_LIBS\@,${libcrypto_LIBS},g' \ < $< > $@ || rm $@ %.pc: %.pc.in Makefile @@ -89,7 +89,7 @@ libkmod_libkmod_la_DEPENDENCIES = \ ${top_srcdir}/libkmod/libkmod.sym libkmod_libkmod_la_LIBADD = \ shared/libshared.la \ - ${liblzma_LIBS} ${zlib_LIBS} ${openssl_LIBS} + ${liblzma_LIBS} ${zlib_LIBS} ${libcrypto_LIBS} noinst_LTLIBRARIES += libkmod/libkmod-internal.la libkmod_libkmod_internal_la_SOURCES = $(libkmod_libkmod_la_SOURCES) diff --git a/configure.ac b/configure.ac index ee72283..dffe278 100644 --- a/configure.ac +++ b/configure.ac @@ -110,12 +110,12 @@ AC_ARG_WITH([openssl], AS_HELP_STRING([--with-openssl], [handle PKCS7 signatures @<:@default=disabled@:>@]), [], [with_openssl=no]) AS_IF([test "x$with_openssl" != "xno"], [ - PKG_CHECK_MODULES([openssl], [openssl >= 1.1.0]) + PKG_CHECK_MODULES([libcrypto], [libcrypto >= 1.1.0]) AC_DEFINE([ENABLE_OPENSSL], [1], [Enable openssl for modinfo.]) ], [ AC_MSG_NOTICE([openssl support not requested]) ]) -CC_FEATURE_APPEND([with_features], [with_openssl], [OPENSSL]) +CC_FEATURE_APPEND([with_features], [with_openssl], [LIBCRYPTO]) AC_ARG_WITH([bashcompletiondir], AS_HELP_STRING([--with-bashcompletiondir=DIR], [Bash completions directory]), -- cgit v1.2.3
