-------------------------------------------------------------------------------- Summary: SELinux is preventing /usr/sbin/tgtd "search" access on /sys. Detailed Description: SELinux denied access requested by tgtd. It is not expected that this access is required by tgtd and this access may signal an intrusion attempt. It is also possible that the specific version or configuration of the application is causing it to require additional access. Allowing Access: You can generate a local policy module to allow this access - see FAQ (http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug report.

This is allowed in F16 policy.
And this is also fixed in the latest RHEL6. You can download pre-release from http://people.redhat.com/dwalsh/SELinux/RHEL6/noarch/
Looks like tgtd is creating the file in "/tmp/.TGT_IPC_ABSTRACT_NAMESPACE.0" </snip> [root@punb200m2labs04vm5 bin]# /etc/init.d/tgtd status tgtd is stopped [root@punb200m2labs04vm5 bin]# ls -l /tmp/.TGT_IPC_ABSTRACT_NAMESPACE.0 ls: cannot access /tmp/.TGT_IPC_ABSTRACT_NAMESPACE.0: No such file or directory [root@punb200m2labs04vm5 bin]# date Tue Sep 13 22:57:57 IST 2011 [root@punb200m2labs04vm5 bin]# /etc/init.d/tgtd start Starting SCSI target daemon: [ OK ] [root@punb200m2labs04vm5 bin]# ls -l /tmp/.TGT_IPC_ABSTRACT_NAMESPACE.0 srwxr-xr-x. 1 root root 0 Sep 13 22:58 /tmp/.TGT_IPC_ABSTRACT_NAMESPACE.0 </snip> But interestingly I am not hitting the issue. After removing the file and rebooting the server and again starting /etc/init.d/tgtd start. I tried one more reboot and start of tgtd, Still cannot hit the issue.
Ignore the comment 4. Accidentally updated the incorrect incident. Was meant for incident 737527.
