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:
We found that there is a possible logical error in the following section in rc.sysinit:
ipaddr=
if [ "$HOSTNAME" = "localhost" -o "$HOSTNAME" = "localhost.localdomain" ]; then
ipaddr=$(ip addr show to 0.0.0.0/0 scope global | awk '/[[:space:]]inet / { print gensub("/.*","","g",$2) }')
for ip in $ipaddr ; do
HOSTNAME=
eval $(ipcalc -h $ipaddr 2>/dev/null)
[ -n "$HOSTNAME" ] && { hostname ${HOSTNAME} ; break; }
done
fi
The "for ip in $ipaddr ; do" loop seems to eval the hostname each of the IP address obtained above and then set the hostname. But it seems that:
eval $(ipcalc -h $ipaddr 2>/dev/null)
should be changed to:
eval $(ipcalc -h $ip 2>/dev/null)
Because if $ipaddr have multiple IP address, ipcalc would not work properly.
Version-Release number of selected component (if applicable):
initscripts-9.03.17-1.el6.x86_64
How reproducible:
Always
Steps to Reproduce:
Actually I don't know how to setup IP address in such early stage of boot. May be using kernel parameter? It need to setup more then 1 ip address to reproduce the problem.
Actual results:
hostname properly set
Expected results:
hostname not set and remain to be localhost
