Subject: [PATCH] nft: Fix selective chain compatibility checks
|
|
|
|
Since commit 80251bc2a56ed ("nft: remove cache build calls"), 'chain'
|
|
parameter passed to nft_chain_list_get() is no longer effective.
|
|
Before, it was used to fetch only that single chain from kernel when
|
|
populating the cache. So the returned list of chains for which
|
|
compatibility checks are done would contain only that single chain.
|
|
|
|
Re-establish the single chain compat checking by introducing a dedicated
|
|
code path to nft_is_chain_compatible() doing so.
|
|
|
|
Fixes: 80251bc2a56ed ("nft: remove cache build calls")
