Mark Andrews cdf73095ab Tighten DNS COOKIE response handling
Fallback to TCP when we have already seen a DNS COOKIE response
from the given address and don't have one in this UDP response. This
could be a server that has turned off DNS COOKIE support, a
misconfigured anycast server with partial DNS COOKIE support, or a
spoofed response. Falling back to TCP is the correct behaviour in
all 3 cases.
