RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Filip Bartmann 2012-12-28 12:24:27 UTC 
Description of problem:
SELinux don't allow postfix to connect to MySQL database if Postfix use external storage for maps

Version-Release number of selected component (if applicable):

selinux-policy.noarch                                                                                                                       3.7.19-189.el6                                                                                                               @selinux
selinux-policy-targeted.noarch                                                                                                              3.7.19-189.el6                                                                                                               @selinux
How reproducible:
Set postfix maps as for example:

virtual_mailbox_domains=mysql:/etc/postfix/domains
virtual_mailbox_maps=mysql:/etc/postfix/mailboxes

Steps to Reproduce:
1. Set Postfix maps as above
2. Send mail to this server

Actual results:
allow postfix_virtual_t mysqld_db_t:dir search;
allow postfix_virtual_t mysqld_t:unix_stream_socket connectto;
allow postfix_virtual_t mysqld_var_run_t:sock_file write;

Expected results:
No entries in audit.log

Additional info:
I suggest to solve this by adding tunable to postfix with 
mysql_stream_connect(postfix_virtual_t)
and so for postgres
Comment 2 Daniel Walsh 2012-12-28 16:24:53 UTC 
Lets back port d3b3143f959f738e805c855b155775478955391d
Comment 5 Michal Trunecka 2013-08-14 08:39:27 UTC 
To backport commit from Comment 2, you would also need to backport postfix_domain attribute, which is missing on RHEL6.

+  optional_policy(`
+       mysql_stream_connect(postfix_domain)
+')

This bug was fixed just this way:

+ mysql_stream_connect(postfix_virtual_t)

was there a reason not to backport suggested rule for whole postfix_domain?
Comment 6 Miroslav Grepl 2013-08-19 13:42:07 UTC 
It was not back ported.
Comment 7 Miroslav Grepl 2013-08-19 13:42:55 UTC 
Basically we don't have postfix_domain attribute in RHEL6.5. Should be also back ported.
