src/sys/netinet6: icmp6.c
Log Message:
Remove the RH0 code from ICMPv6. RH0 is deprecated by RFC5095 (2007) for
security reasons. We already removed it in Route6.
In addition there was an mbuf bug here: calling IP6_EXTHDR_GET twice with
the same offset, but still using the pointer from the first call, which
could have been made invalid. By luck, m_pulldown leaves zero-sized mbufs
in place, instead of freeing them.
And in general, using a 'finaldst' pointer on the mbuf, and then modifying
that mbuf with IP6_EXTHDR_GET with a smaller offset, was really error-
prone.
