FULL PRODUCT VERSION : java version "1.6.0_0" IcedTea6 1.3.1 (Gentoo) Runtime Environment (build 1.6.0_0-b12) OpenJDK 64-Bit Server VM (build 10.0-b19, mixed mode) ADDITIONAL OS VERSION INFORMATION : Linux localhost 2.6.26-hardened-r4 #2 SMP PREEMPT Wed Oct 15 20:24:20 CEST 2008 x86_64 Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz GenuineIntel GNU/Linux EXTRA RELEVANT SYSTEM CONFIGURATION : Kernel hardened with PaX/Grsecurity + hardened toolchain (-> http://www.gentoo.org/proj/en/hardened/) A DESCRIPTION OF THE PROBLEM : During compilation test_gamma executes a task called gamma, which tries to execute something in a memory reagion, where this is not expected (and not allowed by PaX). See also https://bugs.gentoo.org/show_bug.cgi?id=244901 STEPS TO FOLLOW TO REPRODUCE THE PROBLEM : 1. Add PaX support to kernel 2. Compile OpenJDK EXPECTED VERSUS ACTUAL BEHAVIOR : EXPECTED - No action triggering the termination by PaX, JDK compiling ACTUAL - Last lines of build before failure: eam.o yieldingWorkgroup.o vectset.o linux_amd64.o -Wl,-Bstatic -lstdc++ -Wl,-Bdynamic -lm -ldl -lpthread; rm -f libjvm.so.1; ln -s libjvm.so libjvm.so.1; if [ -x /usr/sbin/selinuxenabled ] ; then /usr/sbin/selinuxenabled; if [ $? = 0 ] ; then /usr/bin/chcon -t textrel_shlib_t libjvm.so; if [ $? != 0 ]; then echo "ERROR: Cannot chcon libjvm.so"; exit 1; fi fi fi } Linking vm... { echo Linking launcher...; gcc -m64 -Xlinker -O1 -m64 -export-dynamic -L `pwd` -o gamma launcher.o -ljvm -lm -ldl -lpthread; } Linking launcher... make[6]: Leaving directory `/var/tmp/portage/dev-java/icedtea6-1.3.1/work/icedtea6-1.3.1/openjdk/control/build/linux-amd64/hotspot/outputdir/linux_amd64_compiler2/product' All done. make[5]: Leaving directory `/var/tmp/portage/dev-java/icedtea6-1.3.1/work/icedtea6-1.3.1/openjdk/control/build/linux-amd64/hotspot/outputdir/linux_amd64_compiler2/product' cd linux_amd64_compiler2/product && ./test_gamma ./test_gamma: line 10: 15951 Get��tet ./${gamma:-gamma} -Xbatch -showversion Queens < /dev/null make[4]: *** [product] Fehler 137 make[4]: Leaving directory `/var/tmp/portage/dev-java/icedtea6-1.3.1/work/icedtea6-1.3.1/openjdk/control/build/linux-amd64/hotspot/outputdir' make[3]: *** [generic_build2] Fehler 2 make[3]: Leaving directory `/var/tmp/portage/dev-java/icedtea6-1.3.1/work/icedtea6-1.3.1/openjdk/hotspot/make' make[2]: *** [product] Fehler 2 make[2]: Leaving directory `/var/tmp/portage/dev-java/icedtea6-1.3.1/work/icedtea6-1.3.1/openjdk/hotspot/make' make[1]: *** [hotspot-build] Fehler 2 make[1]: Leaving directory `/var/tmp/portage/dev-java/icedtea6-1.3.1/work/icedtea6-1.3.1/openjdk/control/make' make: *** [stamps/icedtea.stamp] Fehler 2 output of Pax/Grsec: log-2008-10-28-17:10:07:Oct 28 18:13:57 [kernel] PAX: execution attempt in: <anonymous mapping>, 2f95ff054000-2f95ff2c4000 2f95ff054000 log-2008-10-28-17:10:07:Oct 28 18:13:57 [kernel] PAX: terminating task: /var/tmp/portage/dev-java/icedtea6-1.3.1/work/icedtea6-1.3.1/openjdk/control/build/linux-amd64/hotspot/outputdir/linux_amd64_compiler2/product/gamma(gamma):15951, uid/euid: 250/250, PC: 00002f95ff054060, SP: 000077dc7bf16c28 log-2008-10-28-17:10:07:Oct 28 18:13:57 [kernel] PAX: bytes at PC: 85 f6 0f 84 11 00 00 00 0f ae f0 0f ae 3f 48 83 c7 20 ff ce log-2008-10-28-17:10:07:Oct 28 18:13:57 [kernel] PAX: bytes at SP-8: log-2008-10-28-17:10:07:Oct 28 18:13:57 [kernel] grsec: denied resource overstep by requesting 4096 for RLIMIT_CORE against limit 0 for /var/tmp/portage/dev-java/icedtea6-1.3.1/work/icedtea6-1.3.1/openjdk/control/build/linux-amd64/hotspot/outputdir/linux_amd64_compiler2/product/gamma[gamma:15951] uid/euid:250/250 gid/egid:250/250, parent /var/tmp/portage/dev-java/icedtea6-1.3.1/work/icedtea6-1.3.1/openjdk/control/build/linux-amd64/hotspot/outputdir/linux_amd64_compiler2/product/test_gamma[test_gamma:15949] uid/euid:250/250 gid/egid:250/250 REPRODUCIBILITY : This bug can be reproduced always. CUSTOMER SUBMITTED WORKAROUND : Boot a kernel without PaX support and compile it there.
