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 command ipsec barf invokes, among other commands, mii-tool, netstat and ifconfig. These commands are no longer installed by default as they were deprecated and replaced by  ethtool, ss and ip

Version-Release number of selected component (if applicable):
libreswan-3.23-5.el7_5.x86_64

How reproducible:
always

Steps to Reproduce:
1. run ipsec barf


Actual results:
+ netstat -nr
+ head -n 100
/usr/libexec/ipsec/barf: line 158: netstat: command not found

+ ifconfig -a
/usr/libexec/ipsec/barf: line 220: ifconfig: command not found

+ mii-tool -v                                                        
/usr/libexec/ipsec/barf: line 237: mii-tool: command not found      


Expected results:
The above mentioned commands should be replaced by their modern equivalents ( ss, ip a l, ethtool )


Additional info:
The issue is mostly cosmetic but patching /usr/libexec/ipsec/barf is really trivial

Agreed those should be removed.

Note it is mostly cosmetic, as the modern equivalents (ip route list and ip addr show) are also included in the barf output. The way upstream uses this is that if one or the other is available, useful diagnostics are produced by barf.

I do agree that use of ifconfig and netstat can now be removed from ipsec barf

it does seem no ethtool equivalent for mii-tool has been added, which should be fixed.

this has been fixed in upstream 3.28 and will come into rhel8 via rebase
