595: href="https://man.openbsd.org/iwn.4">iwn(4)</a>.
596: <li>Prevented a WPA failure in <a
597: href="https://man.openbsd.org/ipw.4">ipw(4)</a> due to a state
598: mismatch between firmware and net80211 during the association
599: sequence.

1.1 deraadt 608: </ul>
609:
610: <li>IEEE 802.11 wireless stack improvements and bugfixes:
611: <ul>
1.5 benno 612: <li>Fixed the calculation of "maxlen" in <a
613: href="https://man.openbsd.org/iwm.4">iwm(4)</a> and <a
614: href="https://man.openbsd.org/iwx.4">iwx(4)</a> when there are
615: multiple MPDUs in one packet.
616: <li>Fixed 802.11 RSN capabilities announced to peers.
617: <li>Flushed the reorder buffer after gap timeout to prevent frames
618: from remaining in the buffer until the next frame is received.
619: <li>Avoided spurious "input packet decapsulations failed" errors in
620: <a href="https://man.openbsd.org/netstat.1">netstat(1)</a> -W with
621: A-MSDU enabled.
1.17 stsp 622: <li>Introduced RA, a new 11n Tx rate adaptation module for net80211.
1.15 benno 623: Unlike MiRa, RA does not attempt to precisely measure actual

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

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

699: <li>Fixed hangs on amd64 bsd.rd due to misreported core clock
700: frequency on newer Intel Comet Lake models.
1.15 benno 701: <li>Began distributing the gzip'd version of bsd.rd on all platforms

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

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

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

1183: fixed a double-free memory corruption that was introduced in OpenSSH
1184: 8.2 . We treat all such memory faults as potentially exploitable. This
1185: bug could be reached by an attacker with access to the agent socket.<br>
1.3 benno 1186:
1.33 benno 1187: On modern operating systems where the OS can provide information
1188: about the user identity connected to a socket, OpenSSH ssh-agent and
1189: sshd limit agent socket access only to the originating user and root.
1190: Additional mitigation may be afforded by the system's

1273:
1274: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>: for FIDO
1275: keys, if a signature operation fails with a "incorrect PIN" reason and

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

1621: <section id=sourcecode>
1622: <h3>Notes about the source code</h3>
1623: <p>
1624: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1625: This file contains everything you need except for the kernel sources,
1626: which are in a separate archive.
1627: To extract:
1628: <blockquote><pre>
1629: # <kbd>mkdir -p /usr/src</kbd>
1630: # <kbd>cd /usr/src</kbd>
1631: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1632: </pre></blockquote>
1633: <p>
1634: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1635: This file contains all the kernel sources you need to rebuild kernels.
1636: To extract:
1637: <blockquote><pre>
1638: # <kbd>mkdir -p /usr/src/sys</kbd>
1639: # <kbd>cd /usr/src</kbd>
1640: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1641: </pre></blockquote>
1642: <p>
1643: Both of these trees are a regular CVS checkout. Using these trees it
1644: is possible to get a head-start on using the anoncvs servers as
1645: described <a href="anoncvs.html">here</a>.
1646: Using these files
1647: results in a much faster initial CVS update than you could expect from
1648: a fresh checkout of the full OpenBSD source tree.

1654: <h3>Ports Tree</h3>
1655: <p>
1656: A ports tree archive is also provided. To extract:
1657: <blockquote><pre>
1658: # <kbd>cd /usr</kbd>
1659: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1660: </pre></blockquote>
1661: <p>
1662: Go read the <a href="faq/ports/index.html">ports</a> page
1663: if you know nothing about ports
1664: at this point. This text is not a manual of how to use ports.
1665: Rather, it is a set of notes meant to kickstart the user on the
1666: OpenBSD ports system.
1667: <p>
1668: The <i>ports/</i> directory represents a CVS checkout of our ports.
1669: As with our complete source tree, our ports tree is available via
1670: <a href="anoncvs.html">AnonCVS</a>.
1671: So, in order to keep up to date with the -stable branch, you must make
1672: the <i>ports/</i> tree available on a read-write medium and update the tree
1673: with a command like:
1674: <blockquote><pre>
1675: # <kbd>cd /usr/ports</kbd>
1676: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_6_9</kbd>
1677: </pre></blockquote>
1678: <p>
1679: [Of course, you must replace the server name here with a nearby anoncvs
1680: server.]
1681: <p>
1682: Note that most ports are available as packages on our mirrors. Updated
1683: ports for the 6.9 release will be made available if problems arise.
1684: <p>
1685: If you're interested in seeing a port added, would like to help out, or just
1686: would like to know more, the mailing list
1687: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
