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:
No second level directories are presented to the client, after the upgrade to the latest patch (in particular CVE-2017-2619.patch), if the share configuration has the "follow symlinks = no" directive in place, even though there are no symlink in the real path.

Version-Release number of selected component (if applicable):
samba-3.6.23-45.el6_9.x86_64

How reproducible:
Upgrade then place "follow symlinks = no" in the share configuration in smb.conf

Steps to Reproduce:
1. 
2.
3.

Actual results:
Client cannot browse share's subdirectories (all directories in the share seems to be empty).

Expected results:
Disabling the "follow synlinks" or downgrading samba all subdirectories are browsable again.

Additional info:
[2017/09/25 11:26:15.396479,  2] smbd/vfs.c:1047(check_reduced_name)
  check_reduced_name: Bad access attempt: . is a symlink

I can confirm this bug for samba.x86_64 0:3.6.23-45.el6_9

downgrade to previous version samba.x86_64 0:3.6.23-44.el6_9 solved it.

Pavel, you also have 'follow symlinks = no' in your smb.conf file?
