I am trying to change the get_possible_sybil_list function.
If adding the "family" argument is easy, it seems like it would require
changes where the function is called (inside
dirserv_generate_networkstatus_vote_obj, l4535 ), so that one call is made
for IPv6 routers, and one is made for IPv4 routers. I was thinking of
creating two routers list (one IPv4 , one IPv6) but that seems messy.
Wouldn't it be better to filter the "family" directly inside
"get_possible_sybil_list" so as to avoid having to change too many things
?
