Description Martin Kosek 2012-06-11 11:23:27 UTC
Description of problem:

httpd wsgi application can no longer connect to dirsrv socket. I assume this is a regression in Fedora 17, the wsgi script worked for us earlier.

/var/log/audit/audit.log:
type=AVC msg=audit(1339412496.858:270): avc:  denied  { connectto } for  pid=10769 comm="httpd" path="/run/slapd-IDM-LAB-BOS-REDHAT-COM.socket" scontext=system_u:system_r:httpd_t:s0 tcontext=system_u:system_r:dirsrv_t:s0 tclass=unix_stream_socket

Version-Release number of selected component (if applicable):
selinux-policy-targeted-3.10.0-128.fc17.noarch

How reproducible:

Steps to Reproduce:
1. Install freeipa-server package
2. Run ipa-server-install with default options to install an IPA server on host $HOST
3. Open https://$HOST/ipa/migration/
4. Insert admin user credentials that were entered during ipa-server-install
  
Actual results:
Page reports error, AVC is added to audit.log

Expected results:
Operation is allowed

Comment 1 Martin Kosek 2012-06-11 12:22:00 UTC
We just tested that an older selinux-polixy version (selinux-policy-targeted-3.10.0-125.fc17.noarch) allowed this connection.

Comment 5 Martin Kosek 2012-06-12 07:01:37 UTC
I tested that when I set authlogin_nsswitch_use_ldap sebool to true, connection to socket worked. But I don't think we want to always set this option to true when installing IPA, httpd connectes to dirsrv socket for a reason not related to authentication or nsswitch.

There was already a similar discussion in Bug 748366 where named_t could not connect to dirsrv_t.

Comment 6 Martin Kosek 2012-06-12 08:37:22 UTC
Miroslav, you may be right. When I run the tests today, I could not find a selinux-policy version where I would not get the AVC (earlier negative test with selinux-policy-targeted-3.10.0-125.fc17.noarch was done by my colleague).

Still, current selinux-policy does not allow our WSGI script to connect to dirsrv, although now I get slightly different AVC:

type=AVC msg=audit(1339488123.752:1453): avc:  denied  { write } for  pid=21251 comm="httpd" name="slapd-IDM-LAB-BOS-REDHAT-COM.socket" dev="tmpfs" ino=161531 scontext=system_u:system_r:httpd_t:s0 tcontext=system_u:object_r:slapd_var_run_t:s0 tclass=sock_file


I can test any scratch build of the policy it this would help or provide access to the VM I am testing on.
