Summary: SELinux is preventing /home/jarl/sage-4.4.3-linux-32bit-fedora_release_12_constantine_-i686-Linux/local/bin/python from loading /home/jarl/sage-4.4.3-linux-32bit-fedora_release_12_constantine_-i686-Linux/local/lib/libpari-gmp.so.2 which requires text relocation. Detailed Description: The python application attempted to load /home/jarl/sage-4.4.3-linux-32bit-fedora_release_12_constantine_-i686-Linux/local/lib/libpari-gmp.so.2 which requires text relocation. This is a potential security problem. Most libraries do not need this permission. Libraries 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. You can configure SELinux temporarily to allow /home/jarl/sage-4.4.3-linux-32bit-fedora_release_12_constantine_-i686-Linux/local/lib/libpari-gmp.so.2 to use relocation as a workaround, until the library is fixed. Please file a bug report. Allowing Access: If you trust /home/jarl/sage-4.4.3-linux-32bit-fedora_release_12_constantine_-i686-Linux/local/lib/libpari-gmp.so.2 to run correctly, you can change the file context to textrel_shlib_t. "chcon -t textrel_shlib_t '/home/jarl/sage-4.4.3-linux-32bit-fedora_release_12_constantine_-i686-Linux/local/lib/libpari-gmp.so.2'" 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 textrel_shlib_t '/home/jarl/sage-4.4.3-linux-32bit-fedora_release_12_constantine_-i686-Linux/local/lib/libpari-gmp.so.2'" Fix Command: chcon -t textrel_shlib_t '/home/jarl/sage-4.4.3-linux-32bit-fedora_release_12_constantine_-i686-Linux/local/lib/libpari-gmp.so.2' Additional Information: Source Context unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1 023 Target Context unconfined_u:object_r:user_home_t:s0 Target Objects /home/jarl/sage-4.4.3-linux-32bit-fedora_release_1 2_constantine_-i686-Linux/local/lib/libpari- gmp.so.2 [ file ] Source python Source Path /home/jarl/sage-4.4.3-linux-32bit-fedora_release_1 2_constantine_-i686-Linux/local/bin/python Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.7.19-23.fc13 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Plugin Name allow_execmod Host Name (removed) Platform Linux (removed) 2.6.33.5-124.fc13.i686 #1 SMP Fri Jun 11 09:48:40 UTC 2010 i686 i686 Alert Count 2 First Seen Tue 22 Jun 2010 10:46:19 AM BST Last Seen Tue 22 Jun 2010 10:46:19 AM BST Local ID 4c46faff-db10-44ce-972a-82fc1d2b094e Line Numbers Raw Audit Messages node=(removed) type=AVC msg=audit(1277199979.784:60): avc: denied { execmod } for pid=29764 comm="python" path="/home/jarl/sage-4.4.3-linux-32bit-fedora_release_12_constantine_-i686-Linux/local/lib/libpari-gmp.so.2" dev=sda5 ino=1481230 scontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tcontext=unconfined_u:object_r:user_home_t:s0 tclass=file node=(removed) type=SYSCALL msg=audit(1277199979.784:60): arch=40000003 syscall=125 success=no exit=-13 a0=5c5b000 a1=29a000 a2=5 a3=bfee0500 items=0 ppid=29745 pid=29764 auid=500 uid=500 gid=500 euid=500 suid=500 fsuid=500 egid=500 sgid=500 fsgid=500 tty=pts0 ses=1 comm="python" exe="/home/jarl/sage-4.4.3-linux-32bit-fedora_release_12_constantine_-i686-Linux/local/bin/python" subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 key=(null) Hash String generated from allow_execmod,python,unconfined_t,user_home_t,file,execmod audit2allow suggests: #============= unconfined_t ============== #!!!!
