Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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.

Bug 1650297

Summary: error in configuration prevents the rest from loading
Product: Red Hat Enterprise Linux 7 Reporter: Tomas Dolezal <todoleza>
Component: ipsetAssignee: Stefano Brivio <sbrivio>
Status: CLOSED ERRATA QA Contact: Tomas Dolezal <todoleza>
Severity: high Docs Contact: Marc Muehlfeld <mmuehlfe>
Priority: high    
Version: 7.6CC: fgiudici, jmaxwell, pasik, sbrivio, todoleza
Target Milestone: rc   
Target Release: ---   
Hardware: Unspecified   
OS: Unspecified   
Whiteboard:
Fixed In Version: ipset-7.1-1.el7 Doc Type: Bug Fix
Doc Text:
.The `ipset` service now ignores invalid configuration entries during startup The `ipset` service stores configurations as sets in separate files. Previously, when the service started, it restored the configuration from all sets in a single operation, without filtering invalid entries that can be inserted by manually editing a set. As a consequence, if a single configuration entry was invalid, the service did not restore further unrelated sets. The problem has been fixed. As a result, the `ipset` service detects and removes invalid configuration entries during the restore operation, and ignores invalid configuration entries.

This bug is a split of bug 1649877

Version-Release number of selected component (if applicable):
ipset-6.38-3.el7_6.x86_64
ipset-6.38-2.el7.x86_64

How reproducible:
always

Steps to Reproduce:
mkdir /etc/sysconfig/ipset.d/
cat > /etc/sysconfig/ipset.d/a.set <<EOF
create a hash:ip family inet hashsize 1024 maxelem 50
add a 10.20.30.40
EOF
cat > /etc/sysconfig/ipset.d/b.set  <<EOF
create b hash:ip family inet hashsize 1024 maxelem 50
invalid string
add b 10.20.30.41
EOF
cat > /etc/sysconfig/ipset.d/c.set  <<EOF
create c hash:ip family inet hashsize 1024 maxelem 50
add c 10.20.30.42
EOF

systemctl restart ipset
ipset list | egrep Name\|Number
Name: a
Number of entries: 0
Name: b
Number of entries: 0
Name: c
Number of entries: 0
# here there should have been always a 1 entry

echo 'invalid string' > /etc/sysconfig/ipset.d/b.set
systemctl restart ipset
ipset list | egrep Name\|Number
Name: a
Number of entries: 0
# no members and set 'c' is missing

rm /etc/sysconfig/ipset.d/b.set
mkdir /etc/sysconfig/ipset.d/00dir
systemctl restart ipset
ipset list | egrep Name\|Number
Name: a
Number of entries: 1
Name: c
Number of entries: 1

Expected results:
* set members are always present for created sets
* error in file similar to 'b.set' with 'invalid string' does not prevent rest of the sets to be loaded and populated correctly
