Subject: [iptables PATCH v3 01/12] nft: family_ops: Pass nft_handle to 'add' callback
Date: Wed, 30 Oct 2019 18:26:50 +0100 [thread overview]
Message-ID: <20191030172701.5892-2-phil@nwl.cc> (raw)
In-Reply-To: <20191030172701.5892-1-phil@nwl.cc>
In order for add_match() to create anonymous sets when converting
xtables matches it needs access to nft handle. So pass it along from
callers of family ops' add callback.
