Subject: Does ICMP_FRAG_NEEDED automatically update the routing cache?

Am I reading the ipv4 code right?  If a UDP packet we send results in an
ICMP_FRAG_NEEDED packet being received, the cached routing information for the
peer will automatically be updated by __udp4_lib_err()?

And something similar in __udp6_lib_err()?
