1.1 deraadt 127: </ul>
128: <p>
129:
130: <li>Generic network stack improvements:
131: <ul>
1.20 mpi 132: <li> Incoming and forwarded IP packets are now processed without
133: KERNEL_LOCK, resulting in better performances and reduced latency
1.4 florian 134: <li> The kernel no longer handles IPv6 Stateless Address
135: Autoconfiguration (RFC 4862), allowing cleanup and simplification
136: of the IPv6 network stack.
137: <li> The kernel sends IPv6 router solicitations for link local addresses
138: with a link local source address.
1.16 mikeb 139: <li> FQ-CoDel algorithm has been implemented for use with <a
140: href="https://man.openbsd.org/pf.conf#QUEUEING">pf(4) queueing</a>.
1.31 bluhm 141: <li>Improve IPv6 checks for IPsec policies and make them consistent
142: with IPv4.
143: <li>Refactor local IP delivery to process IPsec packets in a flow.
144: Avoid that they are enqueued a second time.
145: <li><a href="https://man.openbsd.org/pf.4">pf(4)</a>
146: looks into AH packets and matches on the inner protocol.
147: This makes IPv4 authentication headers work like IPv6.
148: <li>The length of extension header chains in pf(4) is limited.
149: This prevents spending excessive cpu time on crafted packets.
150: <li>Block IPv6 packets in pf(4) that have hop-by-hop options
151: header or destination options header.
152: Such packets can be passed by adding "allow-opts" to the
153: rule.
154: So IPv6 options are handled like their counterpart in IPv4
155: now.
1.38 jca 156: <li>If the IPv4 ID gets reused too fast, pf(4) fragment reassembly
1.31 bluhm 157: uses a smarter strategy to drop packets.

161:
162: <li>Installer improvements:

1.4 florian 179: Stateless Address Autoconfiguration (RFC 4862).
1.31 bluhm 180: <li> <a href="https://man.openbsd.org/rtadvd.8">rtadvd(8)</a> now supports
1.4 florian 181: "Reducing Energy Consumption of Router Advertisements" (RFC 7772).

183: been fixed to quickly handle IPv6 prefixes changes on the system.
1.31 bluhm 184: <li><a href="https://man.openbsd.org/ipsecctl.8">ipsecctl(8)</a>
185: can show SA bundles now.
186: The keyword "bundle" allows to create them explicitly.
187: This avoids confusion as they were used implicitly before.
188: <li><a href="https://man.openbsd.org/nc.1">nc(1)</a>
189: has got the option -W "recvlimit" to terminate netcat after
190: receiving a number of packets.
191: This allows to send a UDP request, receive a reply and check
192: the result on the command line.
193: <li>Fix a bunch of races in
194: <a href="https://man.openbsd.org/relayd.8">relayd(8)</a>
195: expecially in HTTP chunked mode.
1.37 jca 196: <li><a href="https://man.openbsd.org/ndp.8">ndp(8)</a> shows the

211: <a href="https://man.openbsd.org/malloc.3">malloc(3)</a> option is used.
212: The existing S option now includes F.
1.24 anton 213: <li>The <a href="https://man.openbsd.org/tty.4#TIOCSTI">TIOCSTI</a>
1.19 deraadt 214: tty ioctl has been removed. The I/O-loops in the last two consumers

216: <a href="https://man.openbsd.org/mail.1">mail(1)</a>
1.19 deraadt 217: were rewritten to cope with the removal.
1.29 brynet 218: <li>Trapsleds, a new mitigation that significantly reduces the amount of
1.30 brynet 219: nops in the instruction stream, converting them to traps, making it
220: harder to target potential gadgets.
1.29 brynet 221: <li>Kernel Address Randomized Link (KARL), a new "link-kit" allows the .o
222: files of the kernel to be relinked in a random order, creating a unique
223: kernel for each boot.
224: <li>Like with libc previously,
225: <a href="https://man.openbsd.org/rc.8">rc(8)</a> re-links libcrypto on
226: startup, placing the objects in a random order.
227: <li>In addition to libcrypto, to deter code reuse exploits,
228: <a href="https://man.openbsd.org/rc.8">rc(8)</a> re-links
229: <a href="https://man.openbsd.org/ld.so.1">ld.so</a> on
230: startup, placing the objects in a random order.
1.31 bluhm 231: <li>If process accounting is activated with

233: the daily mail shows pledge violations and program crashes.
234: <a href="https://man.openbsd.org/lastcomm.8">lastcomm(8)</a>
235: uses the flags P and T for such processes.
1.34 brynet 236: <li><a href="https://man.openbsd.org/pflogd.8">pflogd(8)</a> uses the
237: fork+exec model.
238: <li><a href="https://man.openbsd.org/tcpdump.8">tcpdump(8)</a> uses the
239: fork+exec model.
1.39 jca 240: <li><a href="https://man.openbsd.org/ifstated.8">ifstated(8)</a>

755: Make sure you use a properly formatted floppy with NO BAD BLOCKS or your install
756: will most likely fail.

759: You can also write <i>miniroot62.fs</i> to the swap partition on
760: the disk and boot with <i>boot disk:b</i>.
761: <p>
762: <li>
763: If nothing works, you can boot over the network as described in INSTALL.sparc64.

769:
770: If you already have an OpenBSD 6.1 system, and do not want to reinstall,
771: upgrade instructions and advice can be found in the
772: <a href="faq/upgrade62.html">Upgrade Guide</a>.

777: <h3 id="sourcecode"><font color="#0000e0">Notes about the source code</font></h3>
778:
779: <tt>src.tar.gz</tt> contains a source archive starting at <tt>/usr/src</tt>.
780: This file contains everything you need except for the kernel sources,
781: which are in a separate archive.
782: To extract:
783:
784: <blockquote><pre>
785: # <b>mkdir -p /usr/src</b>
786: # <b>cd /usr/src</b>
787: # <b>tar xvfz /tmp/src.tar.gz</b>
788: </pre></blockquote>
789:
790: <tt>sys.tar.gz</tt> contains a source archive starting at <tt>/usr/src/sys</tt>.
791: This file contains all the kernel sources you need to rebuild kernels.
792: To extract:
793:
794: <blockquote><pre>
795: # <b>mkdir -p /usr/src/sys</b>
796: # <b>cd /usr/src</b>
797: # <b>tar xvfz /tmp/sys.tar.gz</b>
798: </pre></blockquote>
799:
800: Both of these trees are a regular CVS checkout. Using these trees it
801: is possible to get a head-start on using the anoncvs servers as
802: described <a href="anoncvs.html">here</a>.
803: Using these files
804: results in a much faster initial CVS update than you could expect from
805: a fresh checkout of the full OpenBSD source tree.

810: <h3 id="ports"><font color="#0000e0">Ports Tree</font></h3>
811:
812: A ports tree archive is also provided. To extract:
813:
814: <blockquote><pre>
815: # <b>cd /usr</b>
816: # <b>tar xvfz /tmp/ports.tar.gz</b>
817: </pre></blockquote>
818:
819: Go read the <a href="faq/ports/index.html">ports</a> page
820: if you know nothing about ports
821: at this point. This text is not a manual of how to use ports.
822: Rather, it is a set of notes meant to kickstart the user on the
823: OpenBSD ports system.
824: <p>
825: The <i>ports/</i> directory represents a CVS checkout of our ports.
826: As with our complete source tree, our ports tree is available via
827: <a href="anoncvs.html">AnonCVS</a>.
828: So, in order to keep up to date with the <i>-stable</i> branch, you must make
829: the <i>ports/</i> tree available on a read-write medium and update the tree
830: with a command like:
831:
832: <blockquote><pre>
833: # <b>cd /usr/ports</b>
1.15 phessler 834: # <b>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_6_2</b>
1.1 deraadt 835: </pre></blockquote>
836:
837: [Of course, you must replace the server name here with a nearby anoncvs
838: server.]
839: <p>
840: Note that most ports are available as packages on our mirrors. Updated
841: ports for the 6.2 release will be made available if problems arise.
842: <p>
843: If you're interested in seeing a port added, would like to help out, or just
844: would like to know more, the mailing list
845: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
