1.63 jsing 224: now inspects AH packets and matches on the inner protocol.
1.31 bluhm 225: This makes IPv4 authentication headers work like IPv6.
226: <li>The length of extension header chains in pf(4) is limited.
1.63 jsing 227: This prevents spending excessive CPU time on crafted packets.
228: <li>Block IPv6 packets in
229: <a href="https://man.openbsd.org/pf.4">pf(4)</a>
230: that have a hop-by-hop options header or a destination options header.
231: Such packets can be passed by adding "allow-opts" to the rule.
232: This makes IPv6 option handling consistent with IPv4.
1.38 jca 233: <li>If the IPv4 ID gets reused too fast, pf(4) fragment reassembly
1.31 bluhm 234: uses a smarter strategy to drop packets.
1.63 jsing 235: <li>Enabled the use of per-CPU caches in the network packet allocators.
1.1 deraadt 236: </ul>
237:
238: <li>Installer improvements:

267: used implicitly.
1.31 bluhm 268: <li><a href="https://man.openbsd.org/nc.1">nc(1)</a>
1.92 bentley 269: now has a <code>-W recvlimit</code> option to terminate netcat after
1.63 jsing 270: receiving the specified number of packets. This allows for a UDP
271: request to be sent, a reply to be received and the result checked on
272: the command line.
1.58 jsing 273: <li><a href="https://man.openbsd.org/nc.1">nc(1)</a>
1.92 bentley 274: now has a <code>-Z</code> option, allowing the peer certificate and chain to be

1.19 deraadt 305: were rewritten to cope with the removal.
1.29 brynet 306: <li>Trapsleds, a new mitigation that significantly reduces the amount of
1.53 deraadt 307: nops in the instruction stream, replacing them with trap instructions
308: or jump-over-trap sequences, thereby requiring greater accuracy for
309: targetting potential gadgets.
1.29 brynet 310: <li>Kernel Address Randomized Link (KARL), a new "link-kit" allows the .o
311: files of the kernel to be relinked in a random order, creating a unique
1.53 deraadt 312: kernel for each boot. /bsd is now non-readable to users, to try to
313: keep the secret.
1.29 brynet 314: <li>Like with libc previously,

1.1 deraadt 560: </ul>
561: <li>New/changed features:
562: <ul>
1.31 bluhm 563: <li>Add RemoteCommand option to specify a command in the
564: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>
565: config file instead of giving it on the client's command
566: line.
567: The feature allows to automate tasks using ssh config.
1.56 djm 568: <li>sshd(8): add ExposeAuthInfo option that enables writing details of
569: the authentication methods used (including public keys where
570: applicable) to a file that is exposed via a $SSH_USER_AUTH
571: environment variable in the subsequent session.
572: <li>ssh(1): add support for reverse dynamic forwarding. In this mode,
573: ssh will act as a SOCKS4/5 proxy and forward connections
574: to destinations requested by the remote SOCKS client. This mode
575: is requested using extended syntax for the -R and RemoteForward
576: options and, because it is implemented solely at the client,
577: does not require the server be updated to be supported.
578: <li>sshd(8): allow LogLevel directive in sshd_config Match blocks.
579: <li>ssh-keygen(1): allow inclusion of arbitrary string or flag
1.67 rob 580: certificate extensions and critical options.
1.56 djm 581: <li>ssh-keygen(1): allow ssh-keygen to use a key held in ssh-agent as
582: a CA when signing certificates.
583: <li>ssh(1)/sshd(8): allow IPQoS=none in ssh/sshd to not set an explicit
584: ToS/DSCP value and just use the operating system default.
585: <li>ssh-add(1): added -q option to make ssh-add quiet on success.
586: <li>ssh(1): expand the StrictHostKeyChecking option with two new
587: settings. The first "accept-new" will automatically accept
588: hitherto-unseen keys but will refuse connections for changed or
589: invalid hostkeys. This is a safer subset of the current behaviour
590: of StrictHostKeyChecking=no. The second setting "off", is a synonym
591: for the current behaviour of StrictHostKeyChecking=no: accept new
592: host keys, and continue connection for hosts with incorrect
593: hostkeys. A future release will change the meaning of
594: StrictHostKeyChecking=no to the behaviour of "accept-new".
595: <li>ssh(1): add SyslogFacility option to ssh(1) matching the equivalent
596: option in sshd(8).
1.1 deraadt 597: </ul>
598: <li>The following significant bugs have been fixed in this release:
599: <ul>
1.56 djm 600: <li>ssh(1): use HostKeyAlias if specified instead of hostname for
1.69 rob 601: matching host certificate principal names.
1.56 djm 602: <li>sftp(1): implement sorting for globbed ls.
603: <li>ssh(1): add a user@host prefix to client's "Permission denied"
604: messages, useful in particular when using "stacked" connections
605: (e.g. ssh -J) where it's not clear which host is denying.
606: <li>ssh(1): accept unknown EXT_INFO extension values that contain \0
607: characters. These are legal, but would previously cause fatal
608: connection errors if received.
609: <li>ssh(1)/sshd(8): repair compression statistics printed at
610: connection exit.
611: <li>sftp(1): print '?' instead of incorrect link count (that the
612: protocol doesn't provide) for remote listings.
613: <li>ssh(1): return failure rather than fatal() for more cases during
614: session multiplexing negotiations. Causes the session to fall back
615: to a non-mux connection if they occur.
616: <li>ssh(1): mention that the server may send debug messages to explain
617: public key authentication problems under some circumstances.
618: <li>Translate OpenSSL error codes to better report incorrect passphrase
619: errors when loading private keys.
620: <li>sshd(8): adjust compatibility patterns for WinSCP to correctly
621: identify versions that implement only the legacy DH group exchange
622: scheme.
623: <li>ssh(1): print the "Killed by signal 1" message only at LogLevel
624: verbose so that it is not shown at the default level; prevents it
625: from appearing during ssh -J and equivalent ProxyCommand configs.
626: <li>ssh-keygen(1): when generating all hostkeys (ssh-keygen -A), clobber
627: existing keys if they exist but are zero length. zero-length keys
628: could previously be made if ssh-keygen failed or was interrupted part
629: way through generating them.
630: <li>ssh(1): fix pledge(2) violation in the escape sequence "~&" used to
631: place the current session in the background.
632: <li>ssh-keyscan(1): avoid double-close() on file descriptors.
633: <li>sshd(8): avoid reliance on shared use of pointers shared between
634: monitor and child sshd processes.
635: <li>sshd_config(8): document available AuthenticationMethods.
636: <li>ssh(1): avoid truncation in some login prompts.
637: <li>ssh(1): make "--" before the hostname terminate argument processing
638: after the hostname too.
639: <li>ssh-keygen(1): switch from aes256-cbc to aes256-ctr for encrypting
640: new-style private keys. Fixes problems related to private key
641: handling for no-OpenSSL builds.
642: <li>ssh(1): warn and do not attempt to use keys when the public and
643: private halves do not match.
644: <li>sftp(1): don't print verbose error message when ssh disconnects
645: from under sftp.
646: <li>sshd(8): fix keepalive scheduling problem: activity on a forwarded
647: port from preventing the keepalive from being sent.
648: <li>sshd(8): when started without root privileges, don't require the
649: privilege separation user or path to exist. Makes running the
650: regression tests easier without touching the filesystem.
651: <li>Make integrity.sh regression tests more robust against timeouts.
652: <li>ssh(1)/sshd(8): correctness fix for channels implementation: accept
653: channel IDs greater than 0x7FFFFFFF.

692: <a href="https://man.openbsd.org/tls_config_free.3">tls_config_free(3)</a>
693: to be called as soon as it has been passed to the final
694: <a href="https://man.openbsd.org/tls_configure.3">tls_configure(3)</a>
695: call, simplifying lifetime tracking for the application.
696: <li>Dropped cipher suites using DSS authentication.
697: <li>Removed support for DSS/DSA from libssl.
698: <li>Distinguish between self-issued certificates and self-signed
699: certificates. The certificate verification code has special cases
700: for self-signed certificates and without this change, self-issued
701: certificates (which it seems are common place with
702: openvpn/easyrsa) were also being included in this category.
703: <li>Added a new TLS extension handling framework and converted all
704: TLS extensions to use it.
705: <li>Improved and added many new manpages. Updated
706: <a href="https://man.openbsd.org/SSL_CTX_check_private_key.3">SSL_{CTX_,}check_private_key(3)</a>
707: manpages with additional cautions regarding their use.
708: <li>Cleaned up and simplified EC key/curve configuration handling.
709: <li>Added
710: <a href="https://man.openbsd.org/tls_config_set_ecdhecurves.3">tls_config_set_ecdhecurves(3)</a>
711: to libtls, which allows the names of the elliptical curves that may
712: be used during client and server key exchange to be specified.
713: <li>Converted more code paths to use CBB/CBS.
714: <li>Removed NPN support - NPN was never standardised and the last draft
715: expired in October 2012.
716: <li>Removed SSL_OP_CRYPTOPRO_TLSEXT_BUG workaround for old/broken
717: CryptoPro clients.
718: <li>Removed support for the TLS padding extension, which was added as a
1.60 jsing 719: workaround for an old bug in F5's TLS termination.
1.65 rob 720: <li>Added ability to clamp notafter values in certificates for systems
1.58 jsing 721: with 32-bit time_t. This is necessary to conform to RFC 5280 4.1.2.5.
722: <li>Removed the original (pre-IETF) chacha20-poly1305 cipher suites.
723: <li>Reclassified ECDHE-RSA-DES-CBC3-SHA from HIGH to MEDIUM.
724: <li>Provide a useful error with libtls if there are no OCSP URLs in a
725: peer certificate.
726: <li>Keep track of which keypair is in use by a TLS context, fixing a bug
727: where a TLS server with SNI would only return the OCSP staple for the
728: default keypair.
729: <li>If
730: <a href="https://man.openbsd.org/tls_config_parse_protocols.3">tls_config_parse_protocols(3)</a>
731: is called with a NULL pointer it now
732: returns the default protocols.

1.92 bentley 1074: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1.1 deraadt 1075: This file contains all the kernel sources you need to rebuild kernels.
1076: To extract:
1077:
1078: <blockquote><pre>
1079: # <b>mkdir -p /usr/src/sys</b>
1080: # <b>cd /usr/src</b>
1081: # <b>tar xvfz /tmp/sys.tar.gz</b>
1082: </pre></blockquote>

1084: Both of these trees are a regular CVS checkout. Using these trees it
1085: is possible to get a head-start on using the anoncvs servers as
1086: described <a href="anoncvs.html">here</a>.
1087: Using these files
1088: results in a much faster initial CVS update than you could expect from
1089: a fresh checkout of the full OpenBSD source tree.

1097: A ports tree archive is also provided. To extract:
1098:
1099: <blockquote><pre>
1100: # <b>cd /usr</b>
1101: # <b>tar xvfz /tmp/ports.tar.gz</b>
1102: </pre></blockquote>
1103:
1104: Go read the <a href="faq/ports/index.html">ports</a> page
1105: if you know nothing about ports
1106: at this point. This text is not a manual of how to use ports.
1107: Rather, it is a set of notes meant to kickstart the user on the
1108: OpenBSD ports system.
1109: <p>
1110: The <i>ports/</i> directory represents a CVS checkout of our ports.
1111: As with our complete source tree, our ports tree is available via
1112: <a href="anoncvs.html">AnonCVS</a>.
1.85 tj 1113: So, in order to keep up to date with the -stable branch, you must make
1.1 deraadt 1114: the <i>ports/</i> tree available on a read-write medium and update the tree
1115: with a command like:
1116:
1117: <blockquote><pre>
1118: # <b>cd /usr/ports</b>
1.15 phessler 1119: # <b>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_6_2</b>
1.1 deraadt 1120: </pre></blockquote>
1121:
1122: [Of course, you must replace the server name here with a nearby anoncvs
1123: server.]
1124: <p>
1125: Note that most ports are available as packages on our mirrors. Updated
1126: ports for the 6.2 release will be made available if problems arise.
1127: <p>
1128: If you're interested in seeing a port added, would like to help out, or just
1129: would like to know more, the mailing list
1130: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
