[PATCH nf,v2] netfilter: nf_tables: disable register tracking

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The register tracking infrastructure is incomplete, it might lead to
generating incorrect ruleset bytecode, disable it by now given we are
late in the release process.

v2: nft_expr_reduce() will be updated later on to re-enable this.
