nft: Fix for zeroing existent builtin chains
|
|
|
|
Previous attempt at fixing for non-existent chains actually broke
|
|
functionality by adding a check for NFTNL_CHAIN_HANDLE right after
|
|
unsetting the attribute.
|
|
|
|
The approach was flawed for another reason, too: Base chains added in
|
|
the same batch (cf. iptables-restore) have no handle either but zeroing
|
|
them may still be sensible.
|
|
|
|
Instead, make use of the new fake chain annotation which identifies
|
|
fakes more reliably.
