Subject: [PATCH net 3/5] netfilter: nf_tables: set last expression in register tracking area
Date: Thu, 20 Jan 2022 13:52:10 +0100	[thread overview]
Message-ID: <20220120125212.991271-4-pablo@netfilter.org> (raw)
In-Reply-To: <20220120125212.991271-1-pablo@netfilter.org>

nft_rule_for_each_expr() sets on last to nft_rule_last(), however, this
is coming after track.last field is set on.

Use nft_expr_last() to set track.last accordingly.

Fixes: 12e4ecfa244b ("netfilter: nf_tables: add register tracking infrastructure")
