in RFC 4620, ICMPv6 Node Information Queries. A vnet jail with an IPv6 address sent a hostname of the host environment, not the jail, even if another hostname was set to the jail. This change can be tested by the following commands: # ifconfig epair0 create # jail -c -n j1 vnet host.hostname=vnetjail path=/ persist # ifconfig epair0b vnet j1 # ifconfig epair0a inet6 -ifdisabled auto_linklocal up # jexec j1 ifconfig epair0b inet6 -ifdisabled auto_linklocal up # ping6 -w ff02::1%epair0a Differential Revision: https://reviews.freebsd.org/D20207 MFC after: 1 week
