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:

The recently released systemd on CentOS Stream 8 tried to re-enable
ping functionality with a systemd sysctl.d entry.

Unfortunately this entry contains a `-` as prefix which is I expect only
valid on newer systemds.

[root@cs8]# grep '^-' /usr/lib/sysctl.d/*
/usr/lib/sysctl.d/50-default.conf:-net.ipv4.ping_group_range = 0 2147483647

Version-Release number of selected component (if applicable):
systemd-239-56.el8.x86_64

How reproducible:

Every time

Steps to Reproduce:
1. Install systemd-239-56.el8.x86_64
2. dnf -y reinstall systemd


Actual results:

The systemd rpm scriptlets output

 Couldn't write '0 2147483647' to '-net/ipv4/ping_group_range', ignoring: No such file or directory

and the intention did not happen:

# cat /proc/sys/net/ipv4/ping_group_range 
1       0

has not been updated.


Expected results:

Should have updated "/proc/sys/net/ipv4/ping_group_range"

Additional info:

I would presume just taking the `-` out should be good.
