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:
RH7.2 snapshot 4 is missing the libnl3-devel package.
In order to compile against libnl3, libnl3-devel is required.

Version-Release number of selected component (if applicable):
The libnl3 version for RH7.2snap4 is libnl3-3.2.21-10.el7.x86_64.

How reproducible:
Trying to compile a library to work with libnl3 is failing.
For example, i'm trying to compile libvma (https://github.com/Mellanox/libvma) which require libnl or libnl3.
Since libnl3-devel does not exist, i have to compile against libnl-devel.
But libvma is also depending on libibverbs which is dependent on libnl3.
As a result, when loading libvma, both libnl3 and libnl are loaded, which causes a crash in libnl3.

Steps to Reproduce:
1.install libvma dependencies: libibverbs, librdmacm
2.compile libvma or any other library or tool depending on libnl3
3.load libvma: LD_PRELOAD=libvma.so ls

Actual results:
ls: route/tc.c:973: rtnl_tc_register: Assertion `0' failed.
Aborted (core dumped)

Expected results:
ls to print files in directory

Additional info:

Which variant are you using? Workstation, Client or Server? Devel packages are usually shipped in optional channel make sure your optional os enabled.

Sorry, i missed the optional channel.
I found the devel package.
thank you!
