[PATCH net 4/7] netfilter: nf_tables: always initialize flowtable hook list in transaction

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

 



The hook list is used if nft_trans_flowtable_update(trans) == true. However,
initialize this list for other cases for safety reasons.
