[PATCH 4/8] netfilter: nf_tables: free chain context when BINDING flag is missing

From: Pablo Neira Ayuso <pablo@netfilter.org>
Date: 2020-08-15 22:19:20
Also in: netfilter-devel
Subsystem: netfilter, networking [general], the rest · Maintainers: Pablo Neira Ayuso, Florian Westphal, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds 

From: Florian Westphal <fw@strlen.de>

syzbot found a memory leak in nf_tables_addchain() because the chain
object is not free'd correctly on error.

Fixes: d0e2c7de92c7 ("netfilter: nf_tables: add NFT_CHAIN_BINDING")
