When upgrading dev-libs/efl-1.11.2 to recent version (1.12.2) on hardened/linux/x86/selinux profile, PaX is killing the elua binary during make process with "PANIC: unprotected error in call to Lua API (runtime code generation failed, restricted kernel?)". Reproducible: Always Steps to Reproduce: 1. tar xvfj efl-1.12.2.tar.bz2 2. cd efl-1.12.2 3. ./configure && make -> unprotected error 4. paxctl -m src/bin/elua/.libs/elua 5. ./configure && make -> now correctly building Expected Results: Makefile should disable PaX's mprotect for elua binary. # emerge efl # ... libtool: link: i686-pc-linux-gnu-gcc -std=gnu99 -O2 -march=native -pipe -Wl,-O1 -Wl,--as-needed -o lib/ecore_x/.libs/ecore_x_vsync lib/ecore_x/lib_ecore_x_ecore_x_vsync-ecore_x_vsync_tool.o lib/ecore_x/lib_ecore_x_ecore_x_vsync-ecore_x_vsync_tool_glx.o -fvisibility=hidden -fdata-sections -ffunction-sections -Wl,--gc-sections -fno-strict-aliasing -Wl,--as-needed -Wl,--no-copy-dt-needed-entries -fvisibility=hidden -fdata-sections -ffunction-sections -Wl,--gc-sections -fno-strict-aliasing -Wl,--as-needed -Wl,--no-copy-dt-needed-entries -fvisibility=hidden -fdata-sections -ffunction-sections -Wl,--gc-sections -fno-strict-aliasing -Wl,--as-needed -Wl,--no-copy-dt-needed-entries lib/efl/.libs/libefl.so lib/ecore/.libs/libecore.so lib/eina/.libs/libeina.so lib/eet/.libs/libeet.so -L/usr/lib lib/eo/.libs/libeo.so lib/ecore_con/.libs/libecore_con.so /var/tmp/portage/dev-libs/efl-1.12.2/work/efl-1.12.2/src/lib/ecore/.libs/libecore.so /var/tmp/portage/dev-libs/efl-1.12.2/work/efl-1.12.2/src/lib/efl/.libs/libefl.so /var/tmp/portage/dev-libs/efl-1.12.2/work/efl-1.12.2/src/lib/eet/.libs/libeet.so -lssl -lcrypto -lz -ljpeg /var/tmp/portage/dev-libs/efl-1.12.2/work/efl-1.12.2/src/lib/eo/.libs/libeo.so /var/tmp/portage/dev-libs/efl-1.12.2/work/efl-1.12.2/src/lib/eina/.libs/libeina.so -lsystemd -lrt -ldl -lpthread -lm ELUA_EOLIAN_LIBRARY_PATH=../src/lib/eolian/.libs EFL_RUN_IN_TREE=1 ../src/bin/elua/elua lualian -I./lib/eo -I./lib/evas/canvas -I./lib/edje -I./lib/efl/interfaces -I./lib/ecore_audio -I./lib/ecore -I./lib/ecore_con -o lib/ecore_audio/ecore_audio_out_pulse.eo.lua lib/ecore_audio/ecore_audio_out_pulse.eo ELUA_EOLIAN_LIBRARY_PATH=../src/lib/eolian/.libs EFL_RUN_IN_TREE=1 ../src/bin/elua/elua lualian -I./lib/eo -I./lib/evas/canvas -I./lib/edje -I./lib/efl/interfaces -I./lib/ecore_audio -I./lib/ecore -I./lib/ecore_con -o lib/ecore_audio/ecore_audio_in_tone.eo.lua lib/ecore_audio/ecore_audio_in_tone.eo ELUA_EOLIAN_LIBRARY_PATH=../src/lib/eolian/.libs EFL_RUN_IN_TREE=1 ../src/bin/elua/elua lualian -I./lib/eo -I./lib/evas/canvas -I./lib/edje -I./lib/efl/interfaces -I./lib/ecore_audio -I./lib/ecore -I./lib/ecore_con -o lib/ecore_con/ecore_con_base.eo.lua lib/ecore_con/ecore_con_base.eo ELUA_EOLIAN_LIBRARY_PATH=../src/lib/eolian/.libs EFL_RUN_IN_TREE=1 ../src/bin/elua/elua lualian -I./lib/eo -I./lib/evas/canvas -I./lib/edje -I./lib/efl/interfaces -I./lib/ecore_audio -I./lib/ecore -I./lib/ecore_con -o lib/ecore_con/ecore_con_client.eo.lua lib/ecore_con/ecore_con_client.eo ELUA_EOLIAN_LIBRARY_PATH=../src/lib/eolian/.libs EFL_RUN_IN_TREE=1 ../src/bin/elua/elua lualian -I./lib/eo -I./lib/evas/canvas -I./lib/edje -I./lib/efl/interfaces -I./lib/ecore_audio -I./lib/ecore -I./lib/ecore_con -o lib/ecore_con/ecore_con_server.eo.lua lib/ecore_con/ecore_con_server.eo ELUA_EOLIAN_LIBRARY_PATH=../src/lib/eolian/.libs EFL_RUN_IN_TREE=1 ../src/bin/elua/elua lualian -I./lib/eo -I./lib/evas/canvas -I./lib/edje -I./lib/efl/interfaces -I./lib/ecore_audio -I./lib/ecore -I./lib/ecore_con -o lib/ecore_con/ecore_con_connector.eo.lua lib/ecore_con/ecore_con_connector.eo PANIC: unprotected error in call to Lua API (runtime code generation failed, restricted kernel?)

It tried paxctl-ng -m /var/tmp/portage/dev-libs/efl-1.13.1/work/efl-1.13.1/src/bin/elua/.libs/elua which did the trick for me.
Created attachment 399814 [details, diff] patch to call paxctl For me the attached patch worked. It is a bit inelegant since paxctl is called before every invokation of the offending binary instead of once after it's creation. Also this hardcodes the path, somebody with autotools-foo could add the proper semantics.
Thanks for your efforts! It's a workable solution. Maybe this patch can be applied during the ebuild process on a hardened-system to avoid these issues!
