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:

Version-Release number of selected component (if applicable):
coreutils-8.4-16.el6
How reproducible:
Always.
Steps to Reproduce:
1. Issuing 'ls -Zl' and 'ls -lZ'
Actual results:
'ls -Zl' shows a list like followings.
# ls -Zl
total 130
dr-xr-xr-x. 2 system_u:object_r:bin_t:s0 root root 4096 Jan 5 17:08 bin
dr-xr-xr-x. 5 system_u:object_r:boot_t:s0 root root 1024 Nov 30 20:36 boot

drwxr-xr-x. 123 system_u:object_r:etc_t:s0 root root 12288 Jan 5 17:08 etc

dr-xr-xr-x. 12 system_u:object_r:lib_t:s0 root root 4096 Jan 5 17:04 lib
'ls -lZ' shows another one.
# ls -lZ
dr-xr-xr-x. root root system_u:object_r:bin_t:s0 bin
dr-xr-xr-x. root root system_u:object_r:boot_t:s0 boot
drwxr-xr-x. root root system_u:object_r:cgroup_t:s0 cgroup
drwxr-xr-x. root root system_u:object_r:device_t:s0 dev
drwxr-xr-x. root root system_u:object_r:etc_t:s0 etc
drwxr-xr-x. root root system_u:object_r:home_root_t:s0 home
dr-xr-xr-x. root root system_u:object_r:lib_t:s0 lib
Expected results:
We can get same results even if the order of options is changed.
Additional info:
In coreutils/src/ls.c patched with SELinux.patch,
1696 case 'l':
1697 format = long_format;
1698 break;
1940 case 'Z':
1941 print_scontext = 1;
1942 format = security_format;
1943 break;
If 'Z' option precedes 'l', the variant 'format' is set to 'long_format'. But 'l' option precedes 'Z', it's set to 'security_format'.
