1.1 deraadt 130: </ul>
131: <p>
132:
133: <li>Generic network stack improvements:
134: <ul>
1.20 mpi 135: <li> Incoming and forwarded IP packets are now processed without
136: KERNEL_LOCK, resulting in better performances and reduced latency
1.4 florian 137: <li> The kernel no longer handles IPv6 Stateless Address
138: Autoconfiguration (RFC 4862), allowing cleanup and simplification
139: of the IPv6 network stack.
140: <li> The kernel sends IPv6 router solicitations for link local addresses
141: with a link local source address.
1.16 mikeb 142: <li> FQ-CoDel algorithm has been implemented for use with <a
143: href="https://man.openbsd.org/pf.conf#QUEUEING">pf(4) queueing</a>.
1.31 bluhm 144: <li>Improve IPv6 checks for IPsec policies and make them consistent
145: with IPv4.
146: <li>Refactor local IP delivery to process IPsec packets in a flow.
147: Avoid that they are enqueued a second time.
148: <li><a href="https://man.openbsd.org/pf.4">pf(4)</a>
149: looks into AH packets and matches on the inner protocol.
150: This makes IPv4 authentication headers work like IPv6.
151: <li>The length of extension header chains in pf(4) is limited.
152: This prevents spending excessive cpu time on crafted packets.
153: <li>Block IPv6 packets in pf(4) that have hop-by-hop options
154: header or destination options header.
155: Such packets can be passed by adding "allow-opts" to the
156: rule.
157: So IPv6 options are handled like their counterpart in IPv4
158: now.
1.38 jca 159: <li>If the IPv4 ID gets reused too fast, pf(4) fragment reassembly
1.31 bluhm 160: uses a smarter strategy to drop packets.

1.31 bluhm 187: <li><a href="https://man.openbsd.org/ipsecctl.8">ipsecctl(8)</a>
188: can show SA bundles now.

190: This avoids confusion as they were used implicitly before.
191: <li><a href="https://man.openbsd.org/nc.1">nc(1)</a>
192: has got the option -W "recvlimit" to terminate netcat after
193: receiving a number of packets.
194: This allows to send a UDP request, receive a reply and check
195: the result on the command line.
196: <li>Fix a bunch of races in
197: <a href="https://man.openbsd.org/relayd.8">relayd(8)</a>
198: expecially in HTTP chunked mode.

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

1.31 bluhm 234: <li>If process accounting is activated with

236: the daily mail shows pledge violations and program crashes.
237: <a href="https://man.openbsd.org/lastcomm.8">lastcomm(8)</a>
238: uses the flags P and T for such processes.
1.34 brynet 239: <li><a href="https://man.openbsd.org/pflogd.8">pflogd(8)</a> uses the
240: fork+exec model.
241: <li><a href="https://man.openbsd.org/tcpdump.8">tcpdump(8)</a> uses the
242: fork+exec model.
1.39 jca 243: <li><a href="https://man.openbsd.org/ifstated.8">ifstated(8)</a>

744: To install, burn cd62.iso on a CD-R, put it in the CD drive of your
745: machine and select <i>Install System Software</i> from the System Maintenance
746: menu. Indigo/Indy/Indigo2 (R4000) systems will not boot automatically from
747: CD-ROM, and need a proper invocation from the PROM prompt.
748: Refer to the instructions in INSTALL.sgi for more details.

752: If your machine doesn't have a CD drive, you can setup a DHCP/tftp network

754: system type. Refer to the instructions in INSTALL.sgi for more details.

794:
795: <tt>src.tar.gz</tt> contains a source archive starting at <tt>/usr/src</tt>.
796: This file contains everything you need except for the kernel sources,
797: which are in a separate archive.
798: To extract:
799:
800: <blockquote><pre>
801: # <b>mkdir -p /usr/src</b>
802: # <b>cd /usr/src</b>
803: # <b>tar xvfz /tmp/src.tar.gz</b>
804: </pre></blockquote>
805:
806: <tt>sys.tar.gz</tt> contains a source archive starting at <tt>/usr/src/sys</tt>.
807: This file contains all the kernel sources you need to rebuild kernels.
808: To extract:
809:
810: <blockquote><pre>
811: # <b>mkdir -p /usr/src/sys</b>
812: # <b>cd /usr/src</b>
813: # <b>tar xvfz /tmp/sys.tar.gz</b>
814: </pre></blockquote>
815:
816: Both of these trees are a regular CVS checkout. Using these trees it
817: is possible to get a head-start on using the anoncvs servers as
818: described <a href="anoncvs.html">here</a>.
819: Using these files
820: results in a much faster initial CVS update than you could expect from
821: a fresh checkout of the full OpenBSD source tree.

827:
828: A ports tree archive is also provided. To extract:

830: <blockquote><pre>
831: # <b>cd /usr</b>

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