Subject: nftables add vs replace
Date: Tue, 21 Jan 2014 11:06:46 +0000	[thread overview]
Message-ID: <20140121110645.GC25197@macbook.localnet> (raw)

We currently only support "add table" and "add chain" with NLM_F_EXCL.
This means we can't replace entire tables without a lot of extra effort,
also its not possible to create tables/chains just in case they don't
already exist.

To fix this, I'd propose to add two new commands, so we have the following:

- add: add without NLM_F_EXCL
- create: add with NLM_F_EXCL
- replace: replace the entire thing

This most likely will also require updates to the transaction handling
so we don't only process rules, but table, chain and set updates in a
transaction.

Comments?
