<pre>I'm using nftables-0.9.3 with libnftnl-1.1.5. I am able to trigger the
assertion mentioned in the summary. Here's how. Firstly, load the following
ruleset:
flush ruleset
table ip metrics {
set servers {
type ipv4_addr
}
chain egress {
type filter hook prerouting priority filter - 1; policy accept;
iifname != "igb0" ct original daddr @servers
}
}
Next, try to list a table by any given name - even the "metrics" table itself:
# nft list table metrics
nft: netlink_delinearize.c:124: netlink_parse_concat_expr: Assertion `consumed
<span class="quote">> 0' failed.</span >
Aborted
I have noticed that the assertion can be avoided by remove the "ct original
daddr @servers" condition from the rule.</pre>
