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 Trevor Hemsley 2017-02-07 23:55:00 UTC 
Created attachment 1248515 [details]
Don't restart dhcpd if a VPN interface comes up

Description of problem:
Bringing up a VPN client connection restarts dhcpd unnecessarily

Version-Release number of selected component (if applicable):
dhcp-4.2.5-47.el7.centos.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Install and configure some form of VPN client connection - I've used both NetworkManager-xl2tpd and vpnc
2. Connect the VPN client to your server and it brings up a new ppp or tun interface
3. NetworkManager runs the dhcp supplied script /etc/NetworkManager/dispatcher.d/12-dhcpd which unconditionally restarts the dhcpd process

Actual results:
Unexpected restart of dhcpd

Expected results:
No unnecesary restart

Additional info:
This script was proposed as part of https://bugzilla.redhat.com/show_bug.cgi?id=565921

Basic patch attached to check interface is ppp* or tun* and exit without restart
