Subject: [PATCH] nft-restore: Fix for deletion of new, referenced rule
|
|
|
|
Combining multiple corner-cases here:
|
|
|
|
* Insert a rule before another new one which is not the first. Triggers
|
|
NFTNL_RULE_ID assignment of the latter.
|
|
|
|
* Delete the referenced new rule in the same batch again. Causes
|
|
overwriting of the previously assigned RULE_ID.
|
|
|
|
Consequently, iptables-nft-restore fails during *insert*, because the
|
|
reference is dangling.
|
