Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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 Robert Krátký 2017-10-21 15:39:51 UTC

https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/selinux_users_and_administrators_guide/chap-security-enhanced_linux-selinux_contexts

Section Number and Name: 
2. SELinux Contexts

Describe the issue: 
"3. An SELinux policy rule states that the passwd_t domain has entrypoint permission to the passwd_exec_t type."

This is confusing as it suggests control flows from the passwd_t domain to the passwd_exec_t type, exactly the opposite of what the rest of the example is showing. I suspect this is because a couple of words were dropped. The sentence should probably be:

"3. An SELinux policy rule states that the passwd_t domain has its entrypoint permission set to the passwd_exec_t type."

See https://access.redhat.com/discussions/3221251

Suggestions for improvement: 
Confirm and reword.
Comment 1 Mirek Jahoda 2018-03-05 15:29:49 UTC 
Mario is right, we use passwd_exec_t as an entrypoint for the passwd_t domain transition.
Comment 2 Mirek Jahoda 2018-03-05 15:42:01 UTC 
The fix has been published on the Customer Portal:
