            Bug ID: 1751
           Summary: ip6tables-restore doesn't restore counters
           Product: iptables
           Version: 1.8.x
          Hardware: x86_64
                OS: Ubuntu
            Status: NEW
          Severity: minor
          Priority: P5
         Component: iptables-restore
          Assignee: netfilter-buglog at lists.netfilter.org
          Reporter: anton.khazan at gmail.com

shell script demonstrating the bug

To reproduce the issue:

ip6tables -X TEST_CNT 2>/dev/null
cat <<EOF | ip6tables-restore -c -n
*filter
:TEST_CNT - [0:0]
[1024:1024] -A TEST_CNT -m comment --comment test_cnt -j ACCEPT
COMMIT
EOF
# end of script

Expected output:
[1024:1024] -A TEST_CNT -m comment --comment test_cnt -j ACCEPT

Actual output:
[0:0] -A TEST_CNT -m comment --comment test_cnt -j ACCEPT


The issue only affects ip6tables-restore (iptables-restore does restore the
counters).

Tested on Linux Mint with nftables.

'ip6tables -V' output:
ip6tables v1.8.7 (nf_tables)

The issue is not happening with ip6tables-restore v1.6.0 on another Debian
system (no nftables installed).
