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:
When accessing a local NFS share through autofs, the mount hangs.
Version-Release number of selected component (if applicable):
kernel-3.10.0-862.6.3.el7.x86_64
autofs-5.0.7-83.el7.x86_64
How reproducible:
Always
Steps to Reproduce:
1. Configure NFS exports like:
/usr/people *(rw,async)
/usr/people/test1 *(rw,async)
/usr/people/test2 *(rw,async)
2. Have autofs configured to access these shares through auto.net or just using
the default /net facility
# cat /etc/auto.master
...
/net -hosts
...
/hosts /etc/auto.net intr,proto=tcp,rw
+auto.master
2. Try to access locally on the same server one of the shares test1 or test2 through /net or /hosts
# cd /net/localhost/usr/people
# cd test1
Actual results:
The mount to test1 hangs
Expected results:
The mount should be successful
