<pre>While I was using nftables to add rules to routing header type 0, I found that
nft list ruleset command prints them incorrectly.
The configuration I was using is shown bellow
nft add table ip6 filter
nft add chain ip6 filter input { type filter hook input priority 0\;}
nft add rule ip6 filter input rt0 addr [1]A::2
nft list ruleset
table ip6 filter {
chain input {
type filter hook input priority 0; policy accept;
hbh unknown 0xa0000000000000000000000000002 [invalid type]
}
}
I'm quite to nftables implementation, but after some walkthrough the code I
think the problem might be as follows:
- when we the struct exthdr_desc for rt0[1], we don't set the type value.
- Then allocation function (exthdr_expr_alloc) allocates an HBH header
template since the type value is 0.
Folks who are more familiar with nftables implementation may have a better
explanation so we can find a fix for the this BUG
