[PATCH nf 1/4] netfilter: nft_nat: correct length for loading protocol registers

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

 



The values in the protocol registers are two bytes wide.  However, when
parsing the register loads, the code currently uses the larger 16-byte
size of a `union nf_inet_addr`.  Change it to use the (correct) size of
a `union nf_conntrack_man_proto` instead.
