Created attachment 377051 [details] Error Dialogue Box Description of problem: Eclipse cannot be launched due to an SELinux policy conflict. I was receiving a JVM error immediately on launching the software. Upon investigation, myself and another user who was experiencing the same problem discovered that it was an SE Linux error. I have tried it with both JBOss Studio Dev and "plain" Eclipse. Version-Release number of selected component (if applicable): Fedora 12 How reproducible: Every time. Steps to Reproduce: 1. Install Eclipse on Fedora 12. http://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/galileo/SR1/eclipse-java-galileo-SR1-linux-gtk.tar.gz Uncompress and click on program icon. OR Test with JBOSS Studio Dev: http://downtown.englab.bne.redhat.com/jbdevstudio.jar and run: java -jar jbdevstudio.jar 2. Run as a normal user with the default SELinux policy enforcing. 3. Actual results: Software fails to launch. Error dialogue and SELinux policy message produced. Expected results: Software should run. Additional info:
Here is the SE Linux error report: Summary: SELinux is preventing /home/dlesage/Desktop/eclipse/eclipse from making the program stack executable. Detailed Description: The eclipse application attempted to make its stack executable. This is a potential security problem. This should never ever be necessary. Stack memory is not executable on most OSes these days and this will not change. Executable stack memory is one of the biggest security problems. An execstack error might in fact be most likely raised by malicious code. Applications are sometimes coded incorrectly and request this permission. The SELinux Memory Protection Tests (http://people.redhat.com/drepper/selinux-mem.html) web page explains how to remove this requirement. If eclipse does not work and you need it to work, you can configure SELinux temporarily to allow this access until the application is fixed. Please file a bug report. Allowing Access: Sometimes a library is accidentally marked with the execstack flag, if you find a library with this flag you can clear it with the execstack -c LIBRARY_PATH. Then retry your application. If the app continues to not work, you can turn the flag back on with execstack -s LIBRARY_PATH. Otherwise, if you trust eclipse to run correctly, you can change the context of the executable to execmem_exec_t. "chcon -t execmem_exec_t '/home/dlesage/Desktop/eclipse/eclipse'" You must also change the default file context files on the system in order to preserve them even on a full relabel. "semanage fcontext -a -t execmem_exec_t '/home/dlesage/Desktop/eclipse/eclipse'" Fix Command: chcon -t execmem_exec_t '/home/dlesage/Desktop/eclipse/eclipse' Additional Information: Source Context unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1 023 Target Context unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1 023 Target Objects None [ process ] Source eclipse Source Path /home/dlesage/jbdevstudio/eclipse/eclipse Port <Unknown> Host localhost.localdomain Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.6.32-55.fc12 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Plugin Name allow_execstack Host Name localhost.localdomain Platform Linux localhost.localdomain 2.6.31.5-127.fc12.i686.PAE #1 SMP Sat Nov 7 21:25:57 EST 2009 i686 i686 Alert Count 2 First Seen Wed 09 Dec 2009 08:36:38 AM EST Last Seen Wed 09 Dec 2009 09:10:33 AM EST Local ID 2c290874-c7f0-461a-a367-a73e164095b3 Line Numbers Raw Audit Messages node=localhost.localdomain type=AVC msg=audit(1260313833.954:24164): avc: denied { execstack } for pid=10504 comm="eclipse" scontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tclass=process node=localhost.localdomain type=SYSCALL msg=audit(1260313833.954:24164): arch=40000003 syscall=125 success=no exit=-13 a0=bfe57000 a1=1000 a2=1000007 a3=bfe56bb0 items=0 ppid=1 pid=10504 auid=500 uid=500 gid=500 euid=500 suid=500 fsuid=500 egid=500 sgid=500 fsgid=500 tty=(none) ses=3064 comm="eclipse" exe="/home/dlesage/Desktop/eclipse/eclipse" subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 key=(null)
