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 Ben Marzinski 2022-08-19 20:03:41 UTC 
+++ This bug was initially created as a clone of Bug #2119887 +++

Description of problem:
multipathd links against readline which, since its adoption by device-mapper-multipath, has been relicensed to GPL-3+. multipathd also use code copied from the linux kernel, which is licensed GPL-2. To resolve the license incompatibility, switch from readline to libedit, which has a compatibility wrapper that makes it a drop-in replacement for readline, and a BSD license compatible with GPLv2.

--- Additional comment from Ben Marzinski on 2022-08-19 20:01:42 UTC ---

There should be no functional change in multipathd. All that is necessary is to verify that installing the new packages installs libedit if not already installed, that

# ldd /sbin/multipathd

no longer includes libreadline and includes libedit instead, and that the interactive prompt you get from running

# multipathd -k

works as before (allowing you to edit what you're typing in).
Comment 4 Lin Li 2022-08-24 11:46:01 UTC 
Reproduced on device-mapper-multipath-0.8.7-10.el9
[root@rdma-qe-42 ~]# rpm -qa | grep multipath
device-mapper-multipath-libs-0.8.7-10.el9.x86_64
device-mapper-multipath-0.8.7-10.el9.x86_64

[root@rdma-qe-42 ~]# ldd /sbin/multipathd | grep libreadline
	libreadline.so.8 => /lib64/libreadline.so.8 (0x00007f4e0ac90000)

[root@rdma-qe-42 ~]# ldd /sbin/multipathd | grep libedit


Verified on device-mapper-multipath-0.8.7-11.el9
[root@storageqe-05 ~]# rpm -qa | grep multipath
device-mapper-multipath-libs-0.8.7-11.el9.x86_64
device-mapper-multipath-0.8.7-11.el9.x86_64
device-mapper-multipath-devel-0.8.7-11.el9.x86_64

[root@storageqe-05 ~]# ldd /sbin/multipathd | grep libreadline
[root@storageqe-05 ~]# ldd /sbin/multipathd | grep libedit
	libedit.so.0 => /lib64/libedit.so.0 (0x00007f19635db000)



Test result: new package no longer includes libreadline and includes libedit instead.
