<div>
<pre>When trying to add a base chain and a regular chain with matching name already
exists, wrong error is printed.
Steps to reproduce the issue:
nft add table test
nft add chain test t # add regular chain t
nft add chain test t { type filter hook postrouting priority 0\; policy
accept\; } # try to add base chain t
Output:
Error: Chain of type "filter" is not supported, perhaps kernel support is
missing?
Expected output: something like
Error: Regular chain "t" already exists.
When the regular chain "t" is removed, the above command works, so I believe
that the actual problem is not lack of support for chain of type "filter" but
rather the fact that same-named regular chain already exists.
Same behavior with nft versions v1.0.8, v1.0.9</pre>
