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.
Previously, a space after Datagram Congestion Control Protocol (DCCP) packet types for print and save was missing, which led to malformed output. With this update, a space has been added at the end of the print_types() function output. As a result, the output of the "iptables -L", "iptables -S", and iptables-save commands is now correct.

Description of problem:
iptables-save cuts space before -j
Version-Release number of selected component (if applicable):
iptables-1.4.7-11.el6.x86_64
How reproducible:
100%
Steps to Reproduce:
---
[root@localhost ~]# iptables -A INPUT -p dccp --dccp-types RESET,INVALID -j LOG --log-level DEBUG --log-prefix "DCCP RESET or INVALID: "
[root@localhost ~]# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
LOG dccp -- anywhere anywhere dccp RESET,INVALIDLOG level debug prefix `DCCP RESET or INVALID: '
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
[root@localhost ~]# iptables-save | grep DCCP
-A INPUT -p dccp -m dccp --dccp-type RESET,INVALID-j LOG --log-prefix "DCCP RESET or INVALID: " --log-level 7
[root@localhost ~]#
---
So, there is no space between INVALID and -j, and rule missed after /etc/init.d/iptables save && reboot .
Actual results:
iptables-save cuts space before -j
Expected results:
There should be space before -j
Additional info:
If i manually add space into /etc/sysconfig/iptables all works.
