1.17 stsp 592: <li>Implemented RA (new 11n Tx rate adaptation) in <a
1.15 benno 593: href="https://man.openbsd.org/iwm.4">iwm(4)</a> and <a
594: href="https://man.openbsd.org/iwn.4">iwn(4)</a>.
595: <li>Prevented a WPA failure in <a
596: href="https://man.openbsd.org/ipw.4">ipw(4)</a> due to a state
597: mismatch between firmware and net80211 during the association
598: sequence.
599: <li>Ensured WEP and plaintext interface link state update by <a

1.1 deraadt 607: </ul>
608:
609: <li>IEEE 802.11 wireless stack improvements and bugfixes:
610: <ul>
1.5 benno 611: <li>Fixed the calculation of "maxlen" in <a

613: href="https://man.openbsd.org/iwx.4">iwx(4)</a> when there are
614: multiple MPDUs in one packet.
615: <li>Fixed 802.11 RSN capabilities announced to peers.
616: <li>Flushed the reorder buffer after gap timeout to prevent frames
617: from remaining in the buffer until the next frame is received.
618: <li>Avoided spurious "input packet decapsulations failed" errors in
619: <a href="https://man.openbsd.org/netstat.1">netstat(1)</a> -W with
620: A-MSDU enabled.
1.17 stsp 621: <li>Introduced RA, a new 11n Tx rate adaptation module for net80211.
1.15 benno 622: Unlike MiRa, RA does not attempt to precisely measure actual

624: throughput which can be achieved by a given MCS.
1.1 deraadt 625: </ul>
626:
627: <li>Generic network stack improvements and bugfixes:
628: <ul>
1.10 benno 629: <li>Removed the direct ACK on every other data segment. After
630: receiving a data segment, we were sending out two ACKs, the first one
631: in tcp_input() direct after receiving and the second ACK after the
632: userland or the sosplice task read some data out of the socket buffer.
633: This change removes the ACK in tcp_input(), saving processing time and
634: improving network performance.
635: <li>Removed the maxburst feature from tcp_output().
636: <li>Added a MONITOR feature to interfaces. Packets received on these
637: interfaces do not enter the network stack for further processing. This
638: can be used to watch traffic, for example with <a
639: href="https://man.openbsd.org/bpf.4">bpf(4)</a> without risk of the packets
640: interfering with the system.
641:
642: <li>Added etherbridge, the internals of a reusable learning bridge
643: interface providing common code reusable for other drivers needing a
644: mac learning bridge.

646: Virtual Ethernet Bridge driver.
1.3 benno 647:
1.15 benno 648: <li>Added the ability to force the selection of source IP address for
649: programs that do not specify a source IP, overriding the default
650: source IP selection algorithm. This is configurable via <a
651: href="https://man.openbsd.org/route.8">route(8)</a>
1.31 tb 652: <code>sourceaddr</code> command.
1.15 benno 653:
654: <li>Bring interfaces up when autoconfiguration for inetor inet6 is
655: enabled (AUTOCONF4 or AUTOCONF6 flags).
656: <li>Adjust terminology in <a
657: href="https://man.openbsd.org/ifconfig.8">ifconfig(8)</a> to refer to
658: "temporary address extensions" rather than the former "privacy
659: extensions," including the addition of an AUTOCONF6TEMP flag (to
660: replace the negative flag "INET6_NOPRIVACY"). The autoconfprivacy
661: option if <a href="https://man.openbsd.org/ifconfig.8">ifconfig(8)</a>
662: has been deprecated.
663: <li>Made it possible to disable the "autoconf" flag but keep
664: "temporary" enabled in <a
665: href="https://man.openbsd.org/ifconfig.8">ifconfig(8)</a>.
666: <li>For IPv6 addresses, added tracking of address proposal creation
667: times to be able to establish total lifetime. This information is used
668: to renew pltime/vltime of privacy addresse per RFC 4941.
1.3 benno 669:
1.15 benno 670: <li>Prevented kernel reuse of mbuf memory when generating the ICMP6
671: response to an IPv6 packet.
672: <li>Use the toeplitz hash algorithm to a flowid for tcp packets,
673: which in turn is used to choose the tx ring on network cards with
674: multiple rings.
675: <li>Fixed <a href="https://man.openbsd.org/wg.4">wg(4)</a> on macppc
676: by keeping track of allowed ips pointer correctly.
677: <li>Fixed <a href="https://man.openbsd.org/wg.4">wg(4)</a> ioctl to
678: handle multiple wgpeers.
679: <li>Fixed a race between tx/rx handshakes in <a
680: href="https://man.openbsd.org/wg.4">wg(4)</a>.
681: <li>Prevented a potential hang when trying to remove a <a
682: href="https://man.openbsd.org/tun.4">tun(4)</a> interface.
683: <li>Used the correct rdomain when adding and deleting routes with <a
684: href="https://man.openbsd.org/mpip.4">mpip(4)</a> and <a
685: href="https://man.openbsd.org/mpw.4">mpw(4)</a>.
686: <li>Made <a href="https://man.openbsd.org/ifconfig.8">ifconfig(8)</a>

707: <li>Prevented <a
708: href="https://man.openbsd.org/disklabel.8">disklabel(8)</a> from
709: adjusting the swap 'b' partition size if physmem is zero to keep the
710: auto-allocate code from putting a filesystem on that partition.
711: <li>Emulate "[inet] autoconf" <a
712: href="https://man.openbsd.org/hostname.if.5">hostname.if(5)</a> lines
713: with "dhcp" so users testing <a
714: href="https://man.openbsd.org/dhcpleased.8">dhcpleased(8)</a> will

723: of <a href="https://man.openbsd.org/printf.3">printf(3)</a> is used.
724: <li>Removed workaround permitting Go executables to do syscalls
725: directly, forcing them to use shared libc like all other dynamic
726: binaries.
1.1 deraadt 727: </ul>
728:
729: <li>Routing daemons and other userland network improvements:
730: <ul>
1.15 benno 731: <li>The <a href="https://man.openbsd.org/bgpd.8">bgpd(8)</a> daemon saw the following changes:
732: <ul>
1.3 benno 733: <li>Fixed a memory leak when parsing <a
734: href="https://man.openbsd.org/bgpd.8">bgpd(8)</a> roa-set lists.
735: <li>Stopped allowing configuration of the same neighbor multiple
736: times in <a href="https://man.openbsd.org/bgpd.8">bgpd(8)</a>.
1.5 benno 737: <li>When exporting prefixes from multiple sessions in <a
738: href="https://man.openbsd.org/bgpd.8">bgpd(8)</a> into the same <a
739: href="https://man.openbsd.org/pf.4">pf(4)</a> table, now prefixes are
740: only removed from the table when withdrawn from all sessions that
741: announced them.
742: <li>Introduced a send hold timer in <a
743: href="https://man.openbsd.org/bgpd.8">bgpd(8)</a> to detect stalls on
744: the sending side of a TCP connection, acting as a last resort to
745: detect faulty peers.
746: <li>Added <a href="https://man.openbsd.org/bgpctl.8">bgpctl(8)</a>
747: "show sets" to display information about the roa-set, as-sets and
748: prefix-sets loaded into <a
749: href="https://man.openbsd.org/bgpd.8">bgpd(8)</a>.
1.10 benno 750: <li>Introduced the <a
751: href="https://man.openbsd.org/bgpd.conf.5">bgpd.conf(5)</a> per
752: neighbor and global config option "reject as-set yes/no" to allow
753: rejection of received UPDATES with AS_SET segments. These rejected
754: prefixes can be viewed with <a
755: href="https://man.openbsd.org/bgpctl.8">bgpctl(8)</a> "show rib in
756: error".
757: <li>Properly implemented "rde med compare strict" in <a
758: href="https://man.openbsd.org/bgpd.8">bgpd(8)</a> and ensured that the
759: order of prefixes is always correct.
760: <li>Added RTR support to <a href="https://man.openbsd.org/bgpd.8">OpenBGPD</a>.
761: <li>Added <a href="https://man.openbsd.org/bgpctl.8">bgpctl(8)</a>
762: "show rtr" to display basic information about RTR sessions.
763: <li>Introduced <a href="https://man.openbsd.org/bgpd.8">bgpd(8)</a>
764: <code>rde evaluate all</code> to work around path hiding in IXP
765: route-server environments.
1.15 benno 766: </ul>
1.10 benno 767:
1.15 benno 768: <li>The <a
769: href="https://man.openbsd.org/ospfd.8">ospfd(8)</a> and <a
770: href="https://man.openbsd.org/ospf6d.8">ospf6d(8)</a> routing
771: daemons saw various internal refactoring to keep the code similar to
772: changes in other routing daemons and improve maintainability.<br>
773: Additionally, support was added in <a
774: href="https://man.openbsd.org/ospfd.8">ospfd(8)</a> for interfaces
775: that share the same IP.
1.10 benno 776:
1.15 benno 777: <li>The <a href="https://man.openbsd.org/pf.4">pf(4)</a> packet filter and it's userland utility:
778: <ul>
779: <li>Relaxed checks in <a
780: href="https://man.openbsd.org/pfctl.8">pfctl(8)</a> and <a
781: href="https://man.openbsd.org/pf.4">pf(4)</a> to accept any valid
782: routing domain, even if it does not yet exist.
783: <li>Made <a href="https://man.openbsd.org/pfctl.8">pfctl(8)</a>
784: detect and reject bogus ranges before loading the ruleset to prevent a
785: panic.
786: <li>Changed route-to in <a
787: href="https://man.openbsd.org/pf.conf.5">pf.conf(5)</a> to send
788: packets to IPs instead of interfaces.
789: <li>Changed pf_route so <a
790: href="https://man.openbsd.org/pf.4">pf(4)</a> only runs when packets
791: enter and leave the stack. Running the same packet through pf multiple
792: times creates confusion for the state table. By default, pf states are
793: floating, meaning that packets are matched to states regardless of
794: which interface they're going over. This diff avoids multiple pf(4)
795: traversals of one packet causing confusion in the state table.
796: <li>Prevented the kernel from being stuck in an endless recursion
797: during TCP path MTU discovery when <a
798: href="https://man.openbsd.org/pf.4">pf(4)</a> changes the routing
799: table when sending packets.
800: <li>When cutting off the head of an overlapping fragment during <a
801: href="https://man.openbsd.org/pf.4">pf(4)</a> reassembly, reinserted
802: the fragment into the lookup table with the correct index.
803: </ul>
1.5 benno 804:
1.15 benno 805: <li>IPSEC support in the kernel and the <a href="https://man.openbsd.org/iked.8">iked(8)</a> userland daemon:
806: <ul>
1.3 benno 807: <li>Added support to request IP addresses as IKEv2 initiator to <a
808: href="https://man.openbsd.org/iked.8">iked(8)</a>. If 'request addr
809: 0.0.0.0' is configured, any address will be accepted.
810: <li>Make <a href="https://man.openbsd.org/iked.8">iked(8)</a> accept
811: ANY dynamic address with 'request addr 0.0.0.0'.
812: <li>Added 'dynamic' keyword to <a
813: href="https://man.openbsd.org/iked.conf.5">iked.conf(5)</a> to allow
814: configuration of flows to dynamically assigned addresses.
815: <li>Added the 'any' keyword to <a
816: href="https://man.openbsd.org/iked.conf.5">iked.conf(5)</a> for
817: requests to allow "request address any".
818: <li>Enabled <a href="https://man.openbsd.org/iked.8">iked(8)</a>
819: support for ASN1_DN ipsec identifiers.
820: <li>Implemented <a href="https://man.openbsd.org/iked.8">iked(8)</a>
821: "from dynamic," installing flows where "dynamic" is replaced by the
822: received dynamic IP address.
823: <li>Made sure not to replace 0.0.0.0 with a dynamic address in <a
824: href="https://man.openbsd.org/iked.8">iked(8)</a> if it is a network
825: address.
826: <li>Added <a href="https://man.openbsd.org/iked.8">iked(8)</a> -s
827: socket option to specify a control socket.
828: <li>Used a counter instead of random IV for AES-GCM in <a
829: href="https://man.openbsd.org/iked.8">iked(8)</a>, eliminating the
830: risk of random collisions.
831: <li>Added <a href="https://man.openbsd.org/iked.8">iked(8)</a>
832: support for multiple address pools.
833: <li>Added the <a href="https://man.openbsd.org/iked.8">iked(8)</a>
834: "set stickyaddress" option, which attempts to assign the same "config
835: address" when an IKESA is negotiated with the DSTID of an existing
836: IKESA.
837: <li>Ensured rekeying of every child SA in <a
838: href="https://man.openbsd.org/iked.8">iked(8)</a>.
1.5 benno 839: <li>Added <a href="https://man.openbsd.org/iked.8">iked(8)</a> support
840: for RSASSA-PSS signature verification (RFC 7427).
841: <li>Corrected the first packet of an <a
842: href="https://man.openbsd.org/ipsec.4">ipsec(4)</a> SA to have
843: sequence number 1.
844: <li>Accepted reject and blackhole routes for IPsec PMTU discovery.
845: <li>Prevented leaking of ipsec_hosts in <a
846: href="https://man.openbsd.org/iked.8">iked(8)</a> when building
847: hosts_list.
848: <li>Prevented initiation of new additional SAs for each policy upon
849: every <a href="https://man.openbsd.org/ikectl.8">ikectl(8)</a> config
850: reload.
851: <li>Fixed "any" and "dynamic" keywords for flows in <a
852: href="https://man.openbsd.org/iked.8">iked(8)</a> and added proper
853: IPv6 support.
1.9 benno 854: <li>Created a path MTU host route for <a
855: href="https://man.openbsd.org/ipsec.4">IPsec(4)</a> over IPv6.
1.10 benno 856: <li>Added support for INVALID_KE_PAYLOAD in <a
857: href="https://man.openbsd.org/iked.8">iked(8)</a> CREATE_CHILD_SA
858: exchange.
859: <li>Added support for RSA-PSS PKCS1 signatures to <a
860: href="https://man.openbsd.org/iked.8">iked(8)</a>.
861: <li>Fixed path MTU discovery for ESP tunnels in IPv6.
862: <li>Upgraded to OpenSSL 1.1 compatible crypto API in <a
863: href="https://man.openbsd.org/iked.8">iked(8)</a>.
864: <li>Added an optional "group none" transform for child SAs in <a
865: href="https://man.openbsd.org/iked.8">iked(8)</a> to ensure the
866: ability to negotiate optional PFS.
867: <li>Added <a href="https://man.openbsd.org/iked.8">iked(8)</a>
868: dynamic address configuration for roadwarrior clients, with a new
869: "iface" config option which can be used to specify an interface for
870: the virtual addresses received from the peer.
1.15 benno 871: <li>Fixed an <a href="https://man.openbsd.org/iked.8">iked(8)</a>
872: interop problem with strongswan if make-before-break is enabled.
873: </ul>
1.3 benno 874:
1.16 tb 875: <li>The <a href="https://man.openbsd.org/httpd.8">httpd(8)</a> webserver saw numerous improvements:
1.15 benno 876: <ul>
877: <li>Prevented a crash due to
878: <a href="https://man.openbsd.org/httpd.8">httpd(8)</a> listening on port
879: 443 with missing TLS certificates.
880: <li>Created a new "location (found|notfound)" option for

1.30 tb 899: <li>Optimized disk reads of
1.15 benno 900: <a href="https://man.openbsd.org/httpd.8">httpd(8)</a>
901: by using st_blocksize as high water mark instead of
902: the socket buffer size.
1.30 tb 903: <li>Do not compare TLS config params for non-TLS servers.
904: This allows using <code>listen on * port 80</code> and

1.28 fcambus 973: by enabling them with <a href="https://man.openbsd.org/rcctl.8">rcctl(8)</a>.
1.15 benno 974: <ul>
975: <li><a href="https://man.openbsd.org/dhcpleased.8">dhcpleased(8)</a>
976: implements the DHCP protocol to acquire IPv4 address leases from
977: servers.

1182: fixed a double-free memory corruption that was introduced in OpenSSH
1183: 8.2 . We treat all such memory faults as potentially exploitable. This
1184: bug could be reached by an attacker with access to the agent socket.<br>
1.3 benno 1185:
1.33 benno 1186: On modern operating systems where the OS can provide information
1187: about the user identity connected to a socket, OpenSSH ssh-agent and
1188: sshd limit agent socket access only to the originating user and root.
1189: Additional mitigation may be afforded by the system's

1191: conditions.<br>
1.3 benno 1192:

1224: replaced with sntrup761x25519-sha512@openssh.com. Per its designers,
1225: the sntrup4591761 algorithm was superseded almost two years ago by
1226: sntrup761.

1229:
1230: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>: disable

1272:
1273: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>: for FIDO
1274: keys, if a signature operation fails with a "incorrect PIN" reason and

1594: floppy</i>. Refer to INSTALL.sparc64 for details.
1595:
1596: <p>
1597: Make sure you use a properly formatted floppy with NO BAD BLOCKS or your install
1598: will most likely fail.
1599:

1612: <p>
1.22 benno 1613: If you already have an OpenBSD 6.8 system, and do not want to reinstall,
1.1 deraadt 1614: upgrade instructions and advice can be found in the

1620: <section id=sourcecode>
1621: <h3>Notes about the source code</h3>
1622: <p>
1623: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1624: This file contains everything you need except for the kernel sources,
1625: which are in a separate archive.
1626: To extract:
1627: <blockquote><pre>
1628: # <kbd>mkdir -p /usr/src</kbd>
1629: # <kbd>cd /usr/src</kbd>
1630: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1631: </pre></blockquote>
1632: <p>
1633: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1634: This file contains all the kernel sources you need to rebuild kernels.
1635: To extract:
1636: <blockquote><pre>
1637: # <kbd>mkdir -p /usr/src/sys</kbd>
1638: # <kbd>cd /usr/src</kbd>
1639: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1640: </pre></blockquote>
1641: <p>
1642: Both of these trees are a regular CVS checkout. Using these trees it
1643: is possible to get a head-start on using the anoncvs servers as
1644: described <a href="anoncvs.html">here</a>.
1645: Using these files
1646: results in a much faster initial CVS update than you could expect from
1647: a fresh checkout of the full OpenBSD source tree.

1653: <h3>Ports Tree</h3>
1654: <p>
1655: A ports tree archive is also provided. To extract:
1656: <blockquote><pre>
1657: # <kbd>cd /usr</kbd>
1658: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1659: </pre></blockquote>
1660: <p>
1661: Go read the <a href="faq/ports/index.html">ports</a> page
1662: if you know nothing about ports
1663: at this point. This text is not a manual of how to use ports.
1664: Rather, it is a set of notes meant to kickstart the user on the
1665: OpenBSD ports system.
1666: <p>
1667: The <i>ports/</i> directory represents a CVS checkout of our ports.
1668: As with our complete source tree, our ports tree is available via
1669: <a href="anoncvs.html">AnonCVS</a>.
1670: So, in order to keep up to date with the -stable branch, you must make
1671: the <i>ports/</i> tree available on a read-write medium and update the tree
1672: with a command like:
1673: <blockquote><pre>
1674: # <kbd>cd /usr/ports</kbd>
1675: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_6_9</kbd>
1676: </pre></blockquote>
1677: <p>
1678: [Of course, you must replace the server name here with a nearby anoncvs
1679: server.]
1680: <p>
1681: Note that most ports are available as packages on our mirrors. Updated
1682: ports for the 6.9 release will be made available if problems arise.
1683: <p>
1684: If you're interested in seeing a port added, would like to help out, or just
1685: would like to know more, the mailing list
1686: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
