            Bug ID: 1732
           Summary: nft list chain does not return correct info on RHEL 8
           Product: nftables
           Version: 1.0.x
          Hardware: x86_64
                OS: RedHat Linux
            Status: NEW
          Severity: blocker
          Priority: P5
         Component: nft
          Assignee: pablo at netfilter.org
          Reporter: herecomeswaynebao0811 at gmail.com

I am seeing a bug using nft on RHEL 8, basically sometimes `nft list
chain` does not return info at all. This is blocking me from using nft further.
Here are the steps to reproduce
it:

nft add table ip filter
nft add chain ip filter forward { type filter hook forward priority 0;
policy accept; }
nft add chain ip filter input { type filter hook forward priority 0;
policy accept; }
nft add chain ip filter grp_test
nft add rule ip filter grp_test ip daddr == 10.1.2.0/24 tcp dport
100-123 counter accept
# now if I `nft list chain ip filter grp_test` it returns the rule

nft add chain ip filter tester
nft add rule ip filter tester counter jump grp_test
# now if I `nft list chain ip filter grp_test` or `nft list chain ip
filter tester`, none of them return info

nft delete rule ip filter grp_test handle 4
# now if I `nft list chain ip filter grp_test` or `nft list chain ip
filter tester`, they return as expected

I am running these on RHEL 8 and these are the version info
