1.1 deraadt 138: </ul>
139: <p>
140:
141: <li>Generic network stack improvements:
142: <ul>
1.20 mpi 143: <li> Incoming and forwarded IP packets are now processed without
144: KERNEL_LOCK, resulting in better performances and reduced latency
1.4 florian 145: <li> The kernel no longer handles IPv6 Stateless Address
146: Autoconfiguration (RFC 4862), allowing cleanup and simplification
147: of the IPv6 network stack.
148: <li> The kernel sends IPv6 router solicitations for link local addresses
149: with a link local source address.
1.16 mikeb 150: <li> FQ-CoDel algorithm has been implemented for use with <a
151: href="https://man.openbsd.org/pf.conf#QUEUEING">pf(4) queueing</a>.

153: with IPv4.
154: <li>Refactor local IP delivery to process IPsec packets in a flow.
155: Avoid that they are enqueued a second time.
156: <li><a href="https://man.openbsd.org/pf.4">pf(4)</a>
157: looks into AH packets and matches on the inner protocol.
158: This makes IPv4 authentication headers work like IPv6.
159: <li>The length of extension header chains in pf(4) is limited.
160: This prevents spending excessive cpu time on crafted packets.
161: <li>Block IPv6 packets in pf(4) that have hop-by-hop options
162: header or destination options header.
163: Such packets can be passed by adding "allow-opts" to the
164: rule.
165: So IPv6 options are handled like their counterpart in IPv4
166: now.
1.38 jca 167: <li>If the IPv4 ID gets reused too fast, pf(4) fragment reassembly
1.31 bluhm 168: uses a smarter strategy to drop packets.

199: This avoids confusion as they were used implicitly before.
200: <li><a href="https://man.openbsd.org/nc.1">nc(1)</a>
201: has got the option -W "recvlimit" to terminate netcat after
202: receiving a number of packets.
203: This allows to send a UDP request, receive a reply and check
204: the result on the command line.
205: <li>Fix a bunch of races in
206: <a href="https://man.openbsd.org/relayd.8">relayd(8)</a>
207: expecially in HTTP chunked mode.

228: <a href="https://man.openbsd.org/mail.1">mail(1)</a>
1.19 deraadt 229: were rewritten to cope with the removal.
1.29 brynet 230: <li>Trapsleds, a new mitigation that significantly reduces the amount of
1.30 brynet 231: nops in the instruction stream, converting them to traps, making it
232: harder to target potential gadgets.
1.29 brynet 233: <li>Kernel Address Randomized Link (KARL), a new "link-kit" allows the .o
234: files of the kernel to be relinked in a random order, creating a unique
235: kernel for each boot.
236: <li>Like with libc previously,
237: <a href="https://man.openbsd.org/rc.8">rc(8)</a> re-links libcrypto on
238: startup, placing the objects in a random order.
239: <li>In addition to libcrypto, to deter code reuse exploits,
240: <a href="https://man.openbsd.org/rc.8">rc(8)</a> re-links

247: uses the flags P and T for such processes.
1.34 brynet 248: <li><a href="https://man.openbsd.org/pflogd.8">pflogd(8)</a> uses the
249: fork+exec model.

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

809: <h3 id="sourcecode"><font color="#0000e0">Notes about the source code</font></h3>
810:
811: <tt>src.tar.gz</tt> contains a source archive starting at <tt>/usr/src</tt>.
812: This file contains everything you need except for the kernel sources,
813: which are in a separate archive.
814: To extract:
815:
816: <blockquote><pre>
817: # <b>mkdir -p /usr/src</b>
818: # <b>cd /usr/src</b>
819: # <b>tar xvfz /tmp/src.tar.gz</b>
820: </pre></blockquote>
821:
822: <tt>sys.tar.gz</tt> contains a source archive starting at <tt>/usr/src/sys</tt>.
823: This file contains all the kernel sources you need to rebuild kernels.
824: To extract:
825:
826: <blockquote><pre>
827: # <b>mkdir -p /usr/src/sys</b>
828: # <b>cd /usr/src</b>
829: # <b>tar xvfz /tmp/sys.tar.gz</b>
830: </pre></blockquote>
831:
832: Both of these trees are a regular CVS checkout. Using these trees it
833: is possible to get a head-start on using the anoncvs servers as
834: described <a href="anoncvs.html">here</a>.
835: Using these files
836: results in a much faster initial CVS update than you could expect from
837: a fresh checkout of the full OpenBSD source tree.

843:
844: A ports tree archive is also provided. To extract:

846: <blockquote><pre>
847: # <b>cd /usr</b>
848: # <b>tar xvfz /tmp/ports.tar.gz</b>
849: </pre></blockquote>
850:
851: Go read the <a href="faq/ports/index.html">ports</a> page
852: if you know nothing about ports
853: at this point. This text is not a manual of how to use ports.
854: Rather, it is a set of notes meant to kickstart the user on the
855: OpenBSD ports system.
856: <p>
857: The <i>ports/</i> directory represents a CVS checkout of our ports.
858: As with our complete source tree, our ports tree is available via
859: <a href="anoncvs.html">AnonCVS</a>.
860: So, in order to keep up to date with the <i>-stable</i> branch, you must make
861: the <i>ports/</i> tree available on a read-write medium and update the tree
862: with a command like:
863:
864: <blockquote><pre>
865: # <b>cd /usr/ports</b>
1.15 phessler 866: # <b>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_6_2</b>
1.1 deraadt 867: </pre></blockquote>
868:
869: [Of course, you must replace the server name here with a nearby anoncvs
870: server.]
871: <p>
872: Note that most ports are available as packages on our mirrors. Updated
873: ports for the 6.2 release will be made available if problems arise.
874: <p>
875: If you're interested in seeing a port added, would like to help out, or just
876: would like to know more, the mailing list
877: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
