1.1 deraadt 139: </ul>

142: <li>Generic network stack improvements:
143: <ul>
1.20 mpi 144: <li> Incoming and forwarded IP packets are now processed without
145: KERNEL_LOCK, resulting in better performances and reduced latency
1.4 florian 146: <li> The kernel no longer handles IPv6 Stateless Address
147: Autoconfiguration (RFC 4862), allowing cleanup and simplification
148: of the IPv6 network stack.

150: with a link local source address.

157: <li><a href="https://man.openbsd.org/pf.4">pf(4)</a>
158: looks into AH packets and matches on the inner protocol.
159: This makes IPv4 authentication headers work like IPv6.
160: <li>The length of extension header chains in pf(4) is limited.
161: This prevents spending excessive cpu time on crafted packets.
162: <li>Block IPv6 packets in pf(4) that have hop-by-hop options
163: header or destination options header.
164: Such packets can be passed by adding "allow-opts" to the

167: now.
1.38 jca 168: <li>If the IPv4 ID gets reused too fast, pf(4) fragment reassembly
1.31 bluhm 169: uses a smarter strategy to drop packets.

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

229: <a href="https://man.openbsd.org/mail.1">mail(1)</a>
1.19 deraadt 230: were rewritten to cope with the removal.
1.29 brynet 231: <li>Trapsleds, a new mitigation that significantly reduces the amount of

1.29 brynet 234: <li>Kernel Address Randomized Link (KARL), a new "link-kit" allows the .o
235: files of the kernel to be relinked in a random order, creating a unique

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

849:
850: A ports tree archive is also provided. To extract:

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