<para>The path MTU discovery for multicast packets in the &os;
&man.ip6.4; stack has been disabled by default because
notifying path MTU by a lot of routers in multicast

<para>The &man.natm.4;, Native Mode ATM protocol layer is now MPSAFE.</para>
<para>A new sysctl variable <varname>net.inet.icmp.reply_from_interface</varname>
has been added. This allows the &man.icmp.4;
reply to non-local packets generated with
the IP address the packet came through in.
This is useful for routers to show in &man.traceroute.8;
the actual path a packet has taken instead of
the possibly different return path.</para>
<para>A new sysctl variable <varname>net.inet.icmp.quotelen</varname>
has been added. This allows to change length of
the quotation of the original packet in an ICMP reply.
The minimum of 8 bytes is internally enforced.
The maximum quotation is the remaining space in the
reply mbuf. This option is added in response to the
issues raised in I-D
<filename>draft-gont-icmp-payload-00.txt</filename>.</para>
<para>The &man.icmp.4; now always quotes the entire TCP header
when responding and allocate an mbuf cluster if needed.
This change fixes the TCP issues raised in I-D
<filename>draft-gont-icmp-payload-00.txt</filename>.</para>
<para>A new socket option <literal>IP_MINTTL</literal> has been added.
This may be used to set the minimum acceptable
TTL a packet must have when received on a socket.
All packets with a lower TTL are silently dropped,
and this works on already connected/connecting and
listening sockets for RAW, UDP, and TCP. This option
is only really useful when set to 255 preventing packets
from outside the directly connected networks reaching
local listeners on sockets. Also, this option allows
userland implementation of <quote>The Generalized TTL
Security Mechanism (GTSM)</quote> found in RFC 3682.</para>
