This is the old common case of initialising the variable structure ip_options, as in ip_sockglue.c or cipso_ipv4.c. But I don't understand how best to do it, because if we change the optbuf type to u32, it might be redundant if we don't change the array size, and therefore I have no idea what boundary to align it on. > Can you make a second patch that places optbuf in the > stack frame of the calling function instead? Into the ipv4_find_option() function?
