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:
When booting with a static IP address configured on kernel command line, the following message is seen:
dracut-initqueue[XXX]: RTNETLINK answers: Network is unreachable
This is due to having the following code snippet in network-legacy dracut module:
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
98 do_static() {
:
104 elif ! linkup "$netif"; then
:
109 ip route get "$ip" | {
110 read a rest
111 if [ "$a" = "local" ]; then
112 warn "Not assigning $ip to interface $netif, cause it is already assigned!"
113 return 1
114 fi
115 return 0
116 } || return 1
:
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
On line 104, a "linkup" is made, but no IP address assigned (that's expected).
Then on line 109 a "ip route get <ip>" is made to check if the <ip> is already assigned.
Due to not having an IP address yet (which is expected), the "RTNETLINK answers: Network is unreachable" message is printed to stderr, while it should be hidden from the user.
Version-Release number of selected component (if applicable):
dracut RH7 and RH8
How reproducible:
Always
Steps to Reproduce:
1. Boot with a static IP address on kernel command line
ip=192.168.122.86::192.168.122.1:24:test:enp1s0:none
2. Check the console or journal
# journalctl -b | grep RTNET
Actual results:
Sep 16 17:17:51 vm-rhel8 dracut-initqueue[472]: RTNETLINK answers: Network is unreachable
Expected results:
Nothing printed
Additional info:
Suggested fix:
109 ip route get "$ip" 2>/dev/null | {
