1.1 deraadt 129: </ul>
130: <p>
131:
132: <li>Generic network stack improvements:
133: <ul>
1.20 mpi 134: <li> Incoming and forwarded IP packets are now processed without
135: KERNEL_LOCK, resulting in better performances and reduced latency
1.4 florian 136: <li> The kernel no longer handles IPv6 Stateless Address
137: Autoconfiguration (RFC 4862), allowing cleanup and simplification
138: of the IPv6 network stack.
139: <li> The kernel sends IPv6 router solicitations for link local addresses
140: with a link local source address.
1.16 mikeb 141: <li> FQ-CoDel algorithm has been implemented for use with <a
142: href="https://man.openbsd.org/pf.conf#QUEUEING">pf(4) queueing</a>.
1.31 bluhm 143: <li>Improve IPv6 checks for IPsec policies and make them consistent
144: with IPv4.
145: <li>Refactor local IP delivery to process IPsec packets in a flow.
146: Avoid that they are enqueued a second time.
147: <li><a href="https://man.openbsd.org/pf.4">pf(4)</a>
148: looks into AH packets and matches on the inner protocol.
149: This makes IPv4 authentication headers work like IPv6.
150: <li>The length of extension header chains in pf(4) is limited.
151: This prevents spending excessive cpu time on crafted packets.
152: <li>Block IPv6 packets in pf(4) that have hop-by-hop options
153: header or destination options header.
154: Such packets can be passed by adding "allow-opts" to the
155: rule.
156: So IPv6 options are handled like their counterpart in IPv4
157: now.
1.38 jca 158: <li>If the IPv4 ID gets reused too fast, pf(4) fragment reassembly
1.31 bluhm 159: uses a smarter strategy to drop packets.

1.45 tb 173: <li> On the amd64 platform, the AES-NI is used if present.
1.1 deraadt 174: </ul>
175: <p>

185: been fixed to quickly handle IPv6 prefixes changes on the system.
1.31 bluhm 186: <li><a href="https://man.openbsd.org/ipsecctl.8">ipsecctl(8)</a>
187: can show SA bundles now.
188: The keyword "bundle" allows to create them explicitly.
189: This avoids confusion as they were used implicitly before.
190: <li><a href="https://man.openbsd.org/nc.1">nc(1)</a>
191: has got the option -W "recvlimit" to terminate netcat after
192: receiving a number of packets.
193: This allows to send a UDP request, receive a reply and check
194: the result on the command line.
195: <li>Fix a bunch of races in
196: <a href="https://man.openbsd.org/relayd.8">relayd(8)</a>
197: expecially in HTTP chunked mode.
1.37 jca 198: <li><a href="https://man.openbsd.org/ndp.8">ndp(8)</a> shows the
199: relevant NDP information when run in a non-default routing
200: domain.
1.40 jca 201: <li><a href="https://man.openbsd.org/ifstated.8">ifstated(8)</a> now
202: copes with interface departures/arrivals.

204: be started multiple times in different
205: <a href="https://man.openbsd.org/rdomain.4">routing domains</a>,
206: this provides virtual router functionality.
1.1 deraadt 207: </ul>
208: <p>
209:
210: <li>Security improvements:
211: <ul>
1.9 otto 212: <li>A new function
213: <a href="https://man.openbsd.org/freezero.3">freezero(3)</a>
214: to easily clear and free memory holding sensitive data has been added.
215: <li>Double free detection has been improved when the F
216: <a href="https://man.openbsd.org/malloc.3">malloc(3)</a> option is used.
217: The existing S option now includes F.
1.24 anton 218: <li>The <a href="https://man.openbsd.org/tty.4#TIOCSTI">TIOCSTI</a>
1.19 deraadt 219: tty ioctl has been removed. The I/O-loops in the last two consumers

1.19 deraadt 222: were rewritten to cope with the removal.
1.29 brynet 223: <li>Trapsleds, a new mitigation that significantly reduces the amount of
1.53 deraadt 224: nops in the instruction stream, replacing them with trap instructions
225: or jump-over-trap sequences, thereby requiring greater accuracy for
226: targetting potential gadgets.
1.29 brynet 227: <li>Kernel Address Randomized Link (KARL), a new "link-kit" allows the .o
228: files of the kernel to be relinked in a random order, creating a unique
1.53 deraadt 229: kernel for each boot. /bsd is now non-readable to users, to try to
230: keep the secret.
1.29 brynet 231: <li>Like with libc previously,
232: <a href="https://man.openbsd.org/rc.8">rc(8)</a> re-links libcrypto on
233: startup, placing the objects in a random order.
234: <li>In addition to libcrypto, to deter code reuse exploits,
235: <a href="https://man.openbsd.org/rc.8">rc(8)</a> re-links
236: <a href="https://man.openbsd.org/ld.so.1">ld.so</a> on
237: startup, placing the objects in a random order.
1.31 bluhm 238: <li>If process accounting is activated with
239: <a href="https://man.openbsd.org/accton.8">accton(8)</a>,
240: the daily mail shows pledge violations and program crashes.
241: <a href="https://man.openbsd.org/lastcomm.8">lastcomm(8)</a>
242: uses the flags P and T for such processes.
1.34 brynet 243: <li><a href="https://man.openbsd.org/pflogd.8">pflogd(8)</a> uses the
244: fork+exec model.
245: <li><a href="https://man.openbsd.org/tcpdump.8">tcpdump(8)</a> uses the
246: fork+exec model.
1.39 jca 247: <li><a href="https://man.openbsd.org/ifstated.8">ifstated(8)</a>
248: uses <a href="https://man.openbsd.org/pledge.2">pledge(2)</a>.
249: <li><a href="https://man.openbsd.org/snmpd.8">snmpd(8)</a> and
250: <a href="https://man.openbsd.org/snmpd.8">snmpctl(8)</a> now use
251: <a href="https://man.openbsd.org/pledge.2">pledge(2)</a>.
1.45 tb 252: <li>Tighter pledge for <a href="https://man.openbsd.org/at.1">at(1)</a>.
253: <li>Fixed and simplified pledge logic for
254: <a href="https://man.openbsd.org/nc.1">nc(1)</a>.
1.53 deraadt 255: <li>More application of recallocarray(3) in userland, and tracked sizes
256: to free(9) in the kernel.
257: <li>Achieve higher levels of paranoia regarding structure packing, and
258: clear many kernel objects before passing to userland.
259: <li>Disable some optimizations in clang(1) due to incompatibility
260: with security.
261: <li>For instance, cope with clang(1)'s assumption that static or const
262: objects placed in unknown sections (such as .openbsd.randomdata)
263: are surely always 0, and therefore such memory accesses can be
264: optimized away..
265: <li>In kernel, randomly bias down the top-of-stack per kthread.

1.1 deraadt 451: </ul>
452: <li>New/changed features:
453: <ul>
1.31 bluhm 454: <li>Add RemoteCommand option to specify a command in the
455: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>
456: config file instead of giving it on the client's command
457: line.
458: The feature allows to automate tasks using ssh config.
1.56 ! djm 459: <li>sshd(8): add ExposeAuthInfo option that enables writing details of
! 460: the authentication methods used (including public keys where
! 461: applicable) to a file that is exposed via a $SSH_USER_AUTH
! 462: environment variable in the subsequent session.
! 463: <li>ssh(1): add support for reverse dynamic forwarding. In this mode,
! 464: ssh will act as a SOCKS4/5 proxy and forward connections
! 465: to destinations requested by the remote SOCKS client. This mode
! 466: is requested using extended syntax for the -R and RemoteForward
! 467: options and, because it is implemented solely at the client,
! 468: does not require the server be updated to be supported.
! 469: <li>sshd(8): allow LogLevel directive in sshd_config Match blocks.
! 470: <li>ssh-keygen(1): allow inclusion of arbitrary string or flag
! 471: certificate extensions and critical options.`
! 472: <li>ssh-keygen(1): allow ssh-keygen to use a key held in ssh-agent as
! 473: a CA when signing certificates.
! 474: <li>ssh(1)/sshd(8): allow IPQoS=none in ssh/sshd to not set an explicit
! 475: ToS/DSCP value and just use the operating system default.
! 476: <li>ssh-add(1): added -q option to make ssh-add quiet on success.
! 477: <li>ssh(1): expand the StrictHostKeyChecking option with two new
! 478: settings. The first "accept-new" will automatically accept
! 479: hitherto-unseen keys but will refuse connections for changed or
! 480: invalid hostkeys. This is a safer subset of the current behaviour
! 481: of StrictHostKeyChecking=no. The second setting "off", is a synonym
! 482: for the current behaviour of StrictHostKeyChecking=no: accept new
! 483: host keys, and continue connection for hosts with incorrect
! 484: hostkeys. A future release will change the meaning of
! 485: StrictHostKeyChecking=no to the behaviour of "accept-new".
! 486: <li>ssh(1): add SyslogFacility option to ssh(1) matching the equivalent
! 487: option in sshd(8).
1.1 deraadt 488: </ul>
489: <li>The following significant bugs have been fixed in this release:
490: <ul>
1.56 ! djm 491: <li>ssh(1): use HostKeyAlias if specified instead of hostname for
! 492: matching host certificate principal names
! 493: <li>sftp(1): implement sorting for globbed ls.
! 494: <li>ssh(1): add a user@host prefix to client's "Permission denied"
! 495: messages, useful in particular when using "stacked" connections
! 496: (e.g. ssh -J) where it's not clear which host is denying.
! 497: <li>ssh(1): accept unknown EXT_INFO extension values that contain \0
! 498: characters. These are legal, but would previously cause fatal
! 499: connection errors if received.
! 500: <li>ssh(1)/sshd(8): repair compression statistics printed at
! 501: connection exit.
! 502: <li>sftp(1): print '?' instead of incorrect link count (that the
! 503: protocol doesn't provide) for remote listings.
! 504: <li>ssh(1): return failure rather than fatal() for more cases during
! 505: session multiplexing negotiations. Causes the session to fall back
! 506: to a non-mux connection if they occur.
! 507: <li>ssh(1): mention that the server may send debug messages to explain
! 508: public key authentication problems under some circumstances.
! 509: <li>Translate OpenSSL error codes to better report incorrect passphrase
! 510: errors when loading private keys.
! 511: <li>sshd(8): adjust compatibility patterns for WinSCP to correctly
! 512: identify versions that implement only the legacy DH group exchange
! 513: scheme.
! 514: <li>ssh(1): print the "Killed by signal 1" message only at LogLevel
! 515: verbose so that it is not shown at the default level; prevents it
! 516: from appearing during ssh -J and equivalent ProxyCommand configs.
! 517: <li>ssh-keygen(1): when generating all hostkeys (ssh-keygen -A), clobber
! 518: existing keys if they exist but are zero length. zero-length keys
! 519: could previously be made if ssh-keygen failed or was interrupted part
! 520: way through generating them.
! 521: <li>ssh(1): fix pledge(2) violation in the escape sequence "~&" used to
! 522: place the current session in the background.
! 523: <li>ssh-keyscan(1): avoid double-close() on file descriptors.
! 524: <li>sshd(8): avoid reliance on shared use of pointers shared between
! 525: monitor and child sshd processes.
! 526: <li>sshd_config(8): document available AuthenticationMethods.
! 527: <li>ssh(1): avoid truncation in some login prompts.
! 528: <li>ssh(1): make "--" before the hostname terminate argument processing
! 529: after the hostname too.
! 530: <li>ssh-keygen(1): switch from aes256-cbc to aes256-ctr for encrypting
! 531: new-style private keys. Fixes problems related to private key
! 532: handling for no-OpenSSL builds.
! 533: <li>ssh(1): warn and do not attempt to use keys when the public and
! 534: private halves do not match.
! 535: <li>sftp(1): don't print verbose error message when ssh disconnects
! 536: from under sftp.
! 537: <li>sshd(8): fix keepalive scheduling problem: activity on a forwarded
! 538: port from preventing the keepalive from being sent.
! 539: <li>sshd(8): when started without root privileges, don't require the
! 540: privilege separation user or path to exist. Makes running the
! 541: regression tests easier without touching the filesystem.
! 542: <li>Make integrity.sh regression tests more robust against timeouts.
! 543: <li>ssh(1)/sshd(8): correctness fix for channels implementation: accept
! 544: channel IDs greater than 0x7FFFFFFF.

919: This file contains everything you need except for the kernel sources,
920: which are in a separate archive.
921: To extract:
922:
923: <blockquote><pre>
924: # <b>mkdir -p /usr/src</b>
925: # <b>cd /usr/src</b>
926: # <b>tar xvfz /tmp/src.tar.gz</b>
927: </pre></blockquote>
928:
929: <tt>sys.tar.gz</tt> contains a source archive starting at <tt>/usr/src/sys</tt>.
930: This file contains all the kernel sources you need to rebuild kernels.
931: To extract:
932:
933: <blockquote><pre>
934: # <b>mkdir -p /usr/src/sys</b>
935: # <b>cd /usr/src</b>
936: # <b>tar xvfz /tmp/sys.tar.gz</b>

939: Both of these trees are a regular CVS checkout. Using these trees it
940: is possible to get a head-start on using the anoncvs servers as
941: described <a href="anoncvs.html">here</a>.
942: Using these files

944: a fresh checkout of the full OpenBSD source tree.

954: # <b>cd /usr</b>
955: # <b>tar xvfz /tmp/ports.tar.gz</b>

957:
958: Go read the <a href="faq/ports/index.html">ports</a> page
959: if you know nothing about ports
960: at this point. This text is not a manual of how to use ports.
961: Rather, it is a set of notes meant to kickstart the user on the
962: OpenBSD ports system.
963: <p>
964: The <i>ports/</i> directory represents a CVS checkout of our ports.
965: As with our complete source tree, our ports tree is available via
966: <a href="anoncvs.html">AnonCVS</a>.
967: So, in order to keep up to date with the <i>-stable</i> branch, you must make
968: the <i>ports/</i> tree available on a read-write medium and update the tree
969: with a command like:
970:
971: <blockquote><pre>
972: # <b>cd /usr/ports</b>
1.15 phessler 973: # <b>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_6_2</b>
1.1 deraadt 974: </pre></blockquote>
975:
976: [Of course, you must replace the server name here with a nearby anoncvs
977: server.]
978: <p>
979: Note that most ports are available as packages on our mirrors. Updated
980: ports for the 6.2 release will be made available if problems arise.
981: <p>
982: If you're interested in seeing a port added, would like to help out, or just
983: would like to know more, the mailing list
984: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
