Description of problem: ============= [root@storageqe-01 ~]# sealert -l d0a4e6c1-0078-40a7-b82d-ae011f3fda6a Summary: SELinux is preventing iscsid (iscsid_t) "connectto" to 004953435349445F5549505F41425354524143545F4E414D455350414345000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 (initrc_t). Detailed Description: SELinux denied access requested by iscsid. It is not expected that this access is required by iscsid 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://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Or you can disable SELinux protection altogether. Disabling SELinux protection is not recommended. Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this package.

Eddie, For RHEL6.2 did you guys have the selinux people do a fix? I did not. I was thinking we should have hit something similar. This looks ok though, and we need to get the selinux policy updated.
Hey Mike, No, I did not either. Is it because the old policy is now obsolete (brcm_iscsiuio vs iscsiuio)? Eddie
Hi Selinux developers, It looks like we need to update the policy for a change in the iscsi tools. I was wondering though, for rhel 5.8 I used the iscsi tools that I put into rhel 6.2. For rhel 6.2 I did not submit any changes for the policy. Did you guys do that for us? I did not see any bzs.
Storage-QE didn't perform any selinux test on bnx2i in 6.2 as we got that card after RHEL 6.2 test plan draft out. Bruno, Can you help us to confirm whether we have same problem on RHEL 6.2 GA?
So the binary was renamed and we need to add /sbin/iscsiuio -- gen_context(system_u:object_r:iscsid_exec_t,s0)
On RHEL 6.2 it worked properly, selinux didn't report any error. I've tested on Kernel 2.6.32-220.el6.
Gris, if you execute # chcon -t iscsid_exec_t /sbin/iscsiuio does it work?
Miroslav, Yes it does work.
Fixed in selinux-policy-2.4.6-321.el5
Yes, I confirmed that with selinux-policy-2.4.6-321.el5 it is working correctly.
