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 of problem:
On a vanilla RHEL 6.1 system installed on HP Proliant hardware and using a serial console via the VSP ilo, booting to Single User Mode results in this error message on the console:
type=1400 audit(1296260632.174:5): avc: denied { write } for pid=1544 comm="sulogin" path="/dev/pts/0" dev=devpts ino=3 scontext=system_u:system_r:sulogin_t:s0 tcontext=system_u:object_r:devpts_t:s0 tclass=chr_file
This prevents the user from getting the normal prompt:
Give root password for maintenance
(or type Control-D to continue):
Setting selinux mode to permissive or disabled fixes the problem.
Version-Release number of selected component (if applicable):
# sestatus
SELinux status: enabled
SELinuxfs mount: /selinux
Current mode: enforcing
Mode from config file: enforcing
Policy version: 24
Policy from config file: targeted
# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.1 (Santiago)
#
How reproducible:
Steps to Reproduce:
1. Configure the system with serial console output via the HP ILO Virtual Serial Port.
2. Edit grub menu or select single user mode grub entry.
3. Wait until init calls sulogin to prompt for password then hand out a shell prompt.
Actual results:
type=1400 audit(1296260632.174:5): avc: denied { write } for pid=1544 comm="sulogin" path="/dev/pts/0" dev=devpts ino=3 scontext=system_u:system_r:sulogin_t:s0 tcontext=system_u:object_r:devpts_t:s0 tclass=chr_file
and no password prompt is displayed to the user
Expected results:
a password prompt like so:
Give root password for maintenance
(or type Control-D to continue):
