Yes, we should fix useland applications.
Set sk->bound_dev (!= 0) if BEFORE connect(2) / bind(2), or they will fail;
Bind(2) / connect(2) without sin6_scope_id while sk->bound_dev_is 0
(or no default value is set) should be invalid.
This is very reasonable behavior.
Or,... we may want to select the default value of sk->bound_dev_if
for link-local address by write to proc file-system like:
# echo 1 > /proc/net/default_linklocal_scopeid
and if connect(2) / bind(2) is called for link-local address without
sin6_scope_id while sk->bound_dev_if is zero, sk->bound_dev_if
will be set to 1 in the connect(2) / bind(2) function.
