2018-11-13openssl-1.1.1: remove build path from version infoMartin Hundebøll
The openssl build system generates buildinf.h containing the full compiler command line used to compile objects. This breaks reproducibility, as the compile command is baked into libcrypto, where it is used when running `openssl version -f`. Add stripped build variables for the compiler and cflags lines, and use those when generating buildinfo.h. This is based on a similar patch for older openssl versions: https://patchwork.openembedded.org/patch/147229/ Signed-off-by: Martin Hundebøll <martin@geanix.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

2018-10-20openssl: do an out-of-tree buildRoss Burton
OpenSSL supports out-of-tree builds so we should use them. This makes builds more reliable, and makes it easier to reduce the size of the ptest package. Signed-off-by: Ross Burton <ross.burton@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2018-10-20openssl: fix ptestRoss Burton
Previously the ptest installation was simply a copy of the entire build tree, which is terribly ugly. Instead copy just the pieces we need, symlink to /usr as appropriate, and add missing dependencies. Remove PRIVATE_LIBS as we don't ship copies of the libraries now. Also remember to do 'set -x' in run-ptest, so if the tests fail the runner knows!

2018-10-16openssl: correct license commentPaul Eggleton
The comment here stated that openssl is dual-licensed, but that would mean that either of the two licenses could be used which is *not* the case [1]. However LICENSE = "openssl" *is* correct because in OE that maps to a generic license file which includes both licenses, which makes sense because there isn't really any such thing as OpenSSL that would be covered by the "OpenSSL license" and not the "SSLeay license".

2018-10-12openssl: use deterministic perl Text::Template module bundled by openssl sourceHongxu Jia
1. The building openssl requires to install perl Text::Template module(>=1.46), but Text::Template is a non core Perl module, openssl chooses to bundle Text::Template 1.46 into the source, for convenience. https://github.com/openssl/openssl/commit/8ff2af548303d311ce3591406111f77862875a60 2.

2018-09-25openssl10: remove extra slash from libdir pathMikko Rapeli
The configure script ended up creating Makefile with LIBDIR=/lib which got leaked into various places including all pkg-config .pc files where lines like (note the double slash //): libdir=${exec_prefix}//lib ... Libs: -L${libdir} -lcrypto which causes pkg-config --libs to include the full absolute path to the recipe specific sysroot. This isn't a big problem until something like CMake projects start generating their own .cmake modules using this absolute path and exposing them to sysroots of other bitbake recipes thus escaping their recipe specific sysroots. Then the fun begins when these users of the .cmake module start to randomly fail builds with error messages like: /home/builder/src/base/build/tmp/work/corei7-64-linux/package/1.0-r0/recipe-sysroot-native/usr/bin/x86_64-linux/../../libexec/x86_64-linux/gcc/x86_64-linux/7.3.0/ld: cannot find /lib/libpthread.so.0 /home/builder/src/base/build/tmp/work/corei7-64-linux/package/1.0-r0/recipe-sysroot-native/usr/bin/x86_64-linux/../../libexec/x86_64-linux/gcc/x86_64-linux/7.3.0/ld: cannot find /usr/lib/libpthread_nonshared.a collect2: error: ld returned 1 exit status ninja: build stopped: subcommand failed. WARNING: exit code 1 from a shell command. As luck has it, this problem goes away by recompiling the recipes alone but repeats with multiple recipes here and there when full images are build. A careful inspection of multi page linker command lines shows that some linker paramaters point to libraries in a different recipes sysroot than what bitbake was building when the task failed. So, fix is to remove this one extra slash from openssl library path configuration option. This changes openssl Makefile to have: LIBDIR=lib and all users of LIBDIR variable in the Makefile are already adding slashes as path separators if that is needed. With this the generated .pc files have: libdir=${exec_prefix}/lib and pkg-config --libs knows to strip the already default sysroot path away. This then fixes the generated .cmake files to not include these absolute paths and fixes the random build failures when building images. Thanks to Thomas, Michael and Ross for debugging support!

Keep the openssl 1.1 recipe aligned with that approach until there's a clear reason to do something else.

The main idea is to have libssl and libcrypto in separate packages. This saves space if only single library is needed and also some recipes (in other layers) depend on these library packages. Together with this other packages like in 1.0.x were created. The only difference is that openssl 1.1 has additional package openssl-bin.

The perlpath.pl script is used to patch the #! lines in all perl scripts in the utils directory. However, as these scripts are run via e.g. "perl foo.pl", they don't actually rely on the #! path to be correct (which can be confirmed by the observation that the path is currently being set to ${STAGING_BINDIR_NATIVE}/perl, which doesn't exist).

The openssl Configure script will only select standalone makedepend (vs running "$CC -M") when building with gcc < 3.x or with an Apple Xcode version which predates the switch to clang (in approx 2010?). Neither of these cases are possible when building under OE, therefore the dependency on makedepend-native can be dropped (ie align the openssl 1.0 recipe with the 1.1 recipe, which has dropped the makedepend-native dependency already).

However, since -e was removed from EXTRA_OEMAKE as part of: http://git.openembedded.org/openembedded-core/commit/?id=537a404cfbb811fcb526cdb5f2e059257de6ef13 exporting these variables does nothing. The comment from that commit that only AR is affected by removing -e wasn't correct, but the effects of letting the openssl Makefile also control AS, EX_LIBS and DIRS seem to be either benign or beneficial. Since without -e make ignores DIRS from the environment and always runs for all subdirs (including "test"), adding "test" to DIRS and calling "make depend" again from do_compile_ptest() can be dropped.

2018-07-26openssl_1.0: fix cryptodev-linux PACKAGECONFIG supportAndre McCurdy
Since openssl isn't an autotools recipe, defining cryptodev-linux related config options via PACKAGECONFIG hasn't worked correctly since PACKAGECONFIG_CONFARGS stopped being automatically appended to EXTRA_OECONF in 2016: http://git.openembedded.org/openembedded-core/commit/?id=c98fb5f5129e71829ffab4449b3d28082bc95ab4 The issue appears to have been hidden as the flags are also hardcoded in CFLAG - and therefore always enabled, regardless of the state of the PACKAGECONFIG option. Fix by passing both EXTRA_OECONF and PACKAGECONFIG_CONFARGS when running the openssl Configure script. Although the openssl 1.1 recipe doesn't contain any PACKAGECONFIG options yet, pre-emptively make the same fix there too.
