<li>SMP Improvements

<li>...

<li>Some network timer run without kernel lock.

<li>TCP syn cache timer runs with shared net lock.

and <a href="https://man.openbsd.org/connect.2">connect(2)</a>

system calls can run in parallel.

<li>Packet counter for <a

href="https://man.openbsd.org/lo.4">lo(4)</a> loopback

interface are MP safe.

<li>Split protocol control block table for UDP into IPv4

and IPv6 tables to allow concurrent access.

<li>UDP packets can be sent in parallel by multiple threads.

<li>Direct Rendering Manager and graphics drivers

<li>Changes in the network stack:

<ul>

<li>Enable IPv6 support in <a href="https://man.openbsd.org/ppp.4">ppp(4)</a>

<li>Enable IPv6 support in <a

<li>...

href="https://man.openbsd.org/ppp.4">ppp(4)</a>

<li>Socket with sequenced packet type and control messages

handle end of record correctly.

<li>The routing table has a generaton number. That means

cached routes at sockets will be invalidated when the routing

table changes. Especially with dynamic routing daemons

local connections use the up to date route.

<li>Route cache hits an misses are printed in

<a href="https://man.openbsd.org/netstat.1">netstat(1)</a>

statistics.

</ul>

<li>The following changes were made to the <a

href="https://man.openbsd.org/pf.4">pf(4)</a> firewall:

<ul>

<li>...

<li>tcpdump on <a

href="https://man.openbsd.org/pflog.4">pflog(4)</a> interface

shows packets dropped by the default rule with the "block"

action. Although the default rules is a "pass" rule, it

blocks malformed packets. Now this is correctly logged.

<li>Routing daemons and other userland network improvements:

Line 323

<li>Many other changes in various network programs and libraries:

<ul>

<li>If a DNS name is configured as remote syslog server,

<a href="https://man.openbsd.org/syslogd.8">syslogd(8)</a>

retries to resolve the name periodically until it succeeds.

UDP packets that get lost during that period are counted and

logged later.
