As I told previously, I just copied the way timeout is built, and therefore, it seems that NFT_CT_TIMEOUT is not used too. But I actually saw today that these values are used in the « nftables » project. There is a copy of nf_tables.h there. Not sure it is a good idea to keep the variables in « nftables » and not in kernel.
