This looks like you were running sulogin? Yes, that is correct. As user, I executed "sudo su -"; then the violation was triggered. sudo su - does not create a process running as sulogin_t. These are the only processes that can transition to sulogin, and as far as I n type_transition initrc_t sulogin_exec_t : process sulogin_t; type_transition openshift_initrc_t sulogin_exec_t : process sulogin_t; type_transition piranha_pulse_t sulogin_exec_t : process sulogin_t; type_transition condor_startd_t sulogin_exec_t : process sulogin_t; type_transition cluster_t sulogin_exec_t : process sulogin_t; type_transition kdumpctl_t sulogin_exec_t : process sulogin_t; type_transition init_t sulogin_exec_t : process sulogin_t; So I have no idea how you got sulogin to fire up, this usually only runs in single user mode. 884ae36eb440ed1d178c0abbf155908d04b18b66 allows this in git. selinux-policy-3.12.1-69.fc19 has been submitted as an update for Fedora 19. https://admin.fedoraproject.org/updates/selinux-policy-3.12.1-69.fc19 Package selinux-policy-3.12.1-69.fc19: * should fix your issue, * was pushed to the Fedora 19 testing repository, * should be available at your local mirror within two days.

If problems still persist, please make note of it in this bug report. |
Description of problem: Unknown. selinux violation popped up while mounting (as sudo su -) an xfs file system at /mnt/f18Root. Running interactive appliations: gnome-terminal. SELinux is preventing /usr/sbin/sulogin from using the 'getpgid' accesses on a process. ***** Plugin catchall (100. confidence) suggests *************************** If you believe that sulogin should be allowed getpgid access on processes labeled init_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 sulogin /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:sulogin_t:s0-s0:c0.c1023 Target Context system_u:system_r:init_t:s0 Target Objects [ process ] Source sulogin Source Path /usr/sbin/sulogin Port <Unknown> Host (removed) Source RPM Packages util-linux-2.23.1-3.fc19.x86_64 Target RPM Packages Policy RPM selinux-policy-3.12.1-65.fc19.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.9.9-302.fc19.x86_64 #1 SMP Sat Jul 6 13:41:07 UTC 2013 x86_64 x86_64 Alert Count 1 First Seen 2013-07-20 10:47:22 EDT Last Seen 2013-07-20 10:47:22 EDT Local ID 6f1b9e84-d4b3-46a3-82af-10b0891f25c3 Raw Audit Messages type=AVC msg=audit(1374331642.261:471): avc: denied { getpgid } for pid=3308 comm="sulogin" scontext=system_u:system_r:sulogin_t:s0-s0:c0.c1023 tcontext=system_u:system_r:init_t:s0 tclass=process type=SYSCALL msg=audit(1374331642.261:471): arch=x86_64 syscall=getpgid success=no exit=EACCES a0=1 a1=4 a2=cec a3=21 items=0 ppid=1 pid=3308 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 ses=4294967295 tty=tty1 comm=sulogin exe=/usr/sbin/sulogin subj=system_u:system_r:sulogin_t:s0-s0:c0.c1023 key=(null) Hash: sulogin,sulogin_t,init_t,process,getpgid Additional info: reporter: libreport-2.1.5 hashmarkername: setroubleshoot kernel: 3.9.9-302.fc19.x86_64 libpeerconnection.log: type: libreport
