What kind of application is Xtend? Java? Mono? You can label this application execmem_exec_t if you want to allow this access. # semanage fcontext -a -t execmem_exec_t PATHTO/Xtend # restorecon -v PATHTO/Xtend |
SELinux is preventing Xtend from using the 'execstack' accesses on a process. ***** Plugin allow_execstack (53.1 confidence) suggests ******************** If you believe that None should not require execstack Then you should clear the execstack flag and see if Xtend works correctly. Report this as a bug on None. You can clear the exestack flag by executing: Do execstack -c None ***** Plugin catchall_boolean (42.6 confidence) suggests ******************* If you want to allow unconfined executables to make their stack executable. This should never, ever be necessary. Probably indicates a badly coded executable, but could indicate an attack. This executable should be reported in bugzilla Then you must tell SELinux about this by enabling the 'allow_execstack' boolean. Do setsebool -P allow_execstack 1 ***** Plugin catchall (5.76 confidence) suggests *************************** If you believe that Xtend should be allowed execstack access on processes labeled unconfined_t by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # grep Xtend /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp 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 Unknown [ process ] Source Xtend Source Path Xtend Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.9.7-25.fc14 Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name (removed) Platform Linux (removed) 2.6.35.10-74.fc14.i686 #1 SMP Thu Dec 23 16:17:40 UTC 2010 i686 i686 Alert Count 5 First Seen Fri 04 Feb 2011 01:52:41 AM EST Last Seen Fri 04 Feb 2011 02:02:12 AM EST Local ID 52be3354-d37f-4751-80dc-76c902229f36 Raw Audit Messages type=AVC msg=audit(1296802932.346:27992): avc: denied { execstack } for pid=2887 comm="Xtend" scontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tclass=process Hash: Xtend,unconfined_t,unconfined_t,process,execstack audit2allow #============= unconfined_t ============== #!!!!
