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the product is no longer active in Red Hat Bugzilla.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.
Description of problem:
Sets with quota elements are possible from the packet path in RHEL9 but impossible from the older nft that ships with RHEL9
Version-Release number of selected component (if applicable):
nftables-1.0.4-10.el9_1.x86_64
How reproducible:
Always
Steps to Reproduce:
1. Use nft -f to load the following
ROOT rhel9 ~% cat /etc/sysconfig/nftables
table ip filter {
set outbound_quota {
type ipv4_addr
size 65535
flags dynamic
elements = { 10.0.0.44 quota over 200 mbytes }
}
}
Actual results:
ROOT rhel9 ~% nft -f /etc/sysconfig/nftables
/etc/sysconfig/nftables:6:40-44: Error: syntax error, unexpected quota, expecting comma or '}'
elements = { 10.0.0.44 quota over 200 mbytes }
^^^^^
Expected results:
The element should load with nft $?=0
Additional info:
Loading the same element is possible in RHEL9 via the packet path
chain OUTPUT {
type filter hook output priority filter; policy accept;
add @outbound_quota { ip saddr quota over 200 mbytes } drop
}
When I build and install nftables-1.0.7-1.fc39.src.rpm from Fedora rawhide, the problem goes away and the element with a quota loads successfully via nft -f.
Probably resolved by backporting the simple commit 9cb501168a623 ("parser_bison: allow to use quota in sets"). I don't see a respective patch for JSON parser though, maybe upstream lacks this feature entirely.
