SELinux is preventing /usr/libexec/gnome-session-check-accelerated-helper from 'execmod' accesses on the file /usr/lib/dri/fglrx_dri.so. ***** Plugin allow_execmod (91.4 confidence) suggests ********************** If you want to allow gnome-session-check-accelerated-helper to have execmod access on the fglrx_dri.so file Then you need to change the label on '/usr/lib/dri/fglrx_dri.so' Do # semanage fcontext -a -t textrel_shlib_t '/usr/lib/dri/fglrx_dri.so' # restorecon -v '/usr/lib/dri/fglrx_dri.so' ***** Plugin catchall (9.59 confidence) suggests *************************** If you believe that gnome-session-check-accelerated-helper should be allowed execmod access on the fglrx_dri.so file 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 gnome-session-c /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:xdm_t:s0-s0:c0.c1023 Target Context system_u:object_r:lib_t:s0 Target Objects /usr/lib/dri/fglrx_dri.so [ file ] Source gnome-session-c Source Path /usr/libexec/gnome-session-check-accelerated- helper Port <Unknown> Host (removed) Source RPM Packages gnome-session-3.0.1-2.fc15 Target RPM Packages xorg-x11-drv-catalyst-libs-11.9-1.fc15 Policy RPM selinux-policy-3.9.16-44.fc15 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 2.6.40.6-0.fc15.i686 #1 SMP Tue Oct 4 00:51:19 UTC 2011 i686 i686 Alert Count 16 First Seen Sun 02 Oct 2011 12:41:28 PM EDT Last Seen Thu 03 Nov 2011 09:35:01 PM EDT Local ID 31a53bce-77a2-4a96-ae2d-f69d68b73b40 Raw Audit Messages type=AVC msg=audit(1320370501.78:70): avc: denied { execmod } for pid=1564 comm="gnome-session-c" path="/usr/lib/dri/fglrx_dri.so" dev=dm-1 ino=149033 scontext=system_u:system_r:xdm_t:s0-s0:c0.c1023 tcontext=system_u:object_r:lib_t:s0 tclass=file type=SYSCALL msg=audit(1320370501.78:70): arch=i386 syscall=mprotect success=no exit=EACCES a0=55c000 a1=1eb7000 a2=5 a3=bfae2ce0 items=0 ppid=1559 pid=1564 auid=4294967295 uid=42 gid=42 euid=42 suid=42 fsuid=42 egid=42 sgid=42 fsgid=42 tty=(none) ses=4294967295 comm=gnome-session-c exe=/usr/libexec/gnome-session-check-accelerated-helper subj=system_u:system_r:xdm_t:s0-s0:c0.c1023 key=(null) Hash: gnome-session-c,xdm_t,lib_t,file,execmod audit2allow #============= xdm_t ============== allow xdm_t lib_t:file execmod; audit2allow -R #============= xdm_t ============== allow xdm_t lib_t:file execmod;
