Subject: [PATCH AUTOSEL 6.6 038/139] netfilter: nf_tables: don't initialize registers in nft_do_chain()
Date: Wed, 25 Sep 2024 08:07:38 -0400	[thread overview]
Message-ID: <20240925121137.1307574-38-sashal@kernel.org> (raw)
In-Reply-To: <20240925121137.1307574-1-sashal@kernel.org>

From: Florian Westphal <fw@strlen.de>

[ Upstream commit c88baabf16d1ef74ab8832de9761226406af5507 ]

revert commit 4c905f6740a3 ("netfilter: nf_tables: initialize registers in
nft_do_chain()").

Previous patch makes sure that loads from uninitialized registers are
detected from the control plane. in this case rule blob auto-zeroes
registers.  Thus the explicit zeroing is not needed anymore.
