Subject: [PATCH nft 0/2] netfilter: nf_tables: Use rcu lock to enhance protection of the lists
Date: Sun, 7 Apr 2024 14:56:03 +0800 [thread overview]
Message-ID: <cover.1712472595.git.william.xuanziyang@huawei.com> (raw)
nf_tables_expressions and nf_tables_objects lists can be concurrent
between type lookup and module unloading process. But there is not
any protection in type lookup process. Therefore, there is pertential
data-race of the lists entry.
Use rcu lock to enhance protection of the lists.

netfilter: nf_tables: Fix potential data-race in __nft_obj_type_get()
