218: <li>Block IPv6 packets in
219: <a href="https://man.openbsd.org/pf.4">pf(4)</a>
220: that have a hop-by-hop options header or a destination options header.
221: Such packets can be passed by adding "allow-opts" to the rule.
222: This makes IPv6 option handling consistent with IPv4.
1.38 jca 223: <li>If the IPv4 ID gets reused too fast, pf(4) fragment reassembly
1.31 bluhm 224: uses a smarter strategy to drop packets.

1.31 bluhm 561: <li>Add RemoteCommand option to specify a command in the
562: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>
563: config file instead of giving it on the client's command
564: line.
565: The feature allows to automate tasks using ssh config.
1.56 djm 566: <li>sshd(8): add ExposeAuthInfo option that enables writing details of
567: the authentication methods used (including public keys where
568: applicable) to a file that is exposed via a $SSH_USER_AUTH
569: environment variable in the subsequent session.
570: <li>ssh(1): add support for reverse dynamic forwarding. In this mode,
571: ssh will act as a SOCKS4/5 proxy and forward connections
572: to destinations requested by the remote SOCKS client. This mode
573: is requested using extended syntax for the -R and RemoteForward
574: options and, because it is implemented solely at the client,
575: does not require the server be updated to be supported.
576: <li>sshd(8): allow LogLevel directive in sshd_config Match blocks.
577: <li>ssh-keygen(1): allow inclusion of arbitrary string or flag
1.67 rob 578: certificate extensions and critical options.
1.56 djm 579: <li>ssh-keygen(1): allow ssh-keygen to use a key held in ssh-agent as
580: a CA when signing certificates.
581: <li>ssh(1)/sshd(8): allow IPQoS=none in ssh/sshd to not set an explicit
582: ToS/DSCP value and just use the operating system default.
583: <li>ssh-add(1): added -q option to make ssh-add quiet on success.
584: <li>ssh(1): expand the StrictHostKeyChecking option with two new
585: settings. The first "accept-new" will automatically accept
586: hitherto-unseen keys but will refuse connections for changed or
587: invalid hostkeys. This is a safer subset of the current behaviour
588: of StrictHostKeyChecking=no. The second setting "off", is a synonym
589: for the current behaviour of StrictHostKeyChecking=no: accept new
590: host keys, and continue connection for hosts with incorrect
591: hostkeys. A future release will change the meaning of
592: StrictHostKeyChecking=no to the behaviour of "accept-new".
593: <li>ssh(1): add SyslogFacility option to ssh(1) matching the equivalent
594: option in sshd(8).
1.1 deraadt 595: </ul>
596: <li>The following significant bugs have been fixed in this release:

1.69 rob 599: matching host certificate principal names.
1.56 djm 600: <li>sftp(1): implement sorting for globbed ls.
601: <li>ssh(1): add a user@host prefix to client's "Permission denied"
602: messages, useful in particular when using "stacked" connections
603: (e.g. ssh -J) where it's not clear which host is denying.
604: <li>ssh(1): accept unknown EXT_INFO extension values that contain \0
605: characters. These are legal, but would previously cause fatal
606: connection errors if received.
607: <li>ssh(1)/sshd(8): repair compression statistics printed at
608: connection exit.
609: <li>sftp(1): print '?' instead of incorrect link count (that the
610: protocol doesn't provide) for remote listings.
611: <li>ssh(1): return failure rather than fatal() for more cases during
612: session multiplexing negotiations. Causes the session to fall back
613: to a non-mux connection if they occur.
614: <li>ssh(1): mention that the server may send debug messages to explain
615: public key authentication problems under some circumstances.
616: <li>Translate OpenSSL error codes to better report incorrect passphrase
617: errors when loading private keys.
618: <li>sshd(8): adjust compatibility patterns for WinSCP to correctly
619: identify versions that implement only the legacy DH group exchange
620: scheme.
621: <li>ssh(1): print the "Killed by signal 1" message only at LogLevel
622: verbose so that it is not shown at the default level; prevents it
623: from appearing during ssh -J and equivalent ProxyCommand configs.
624: <li>ssh-keygen(1): when generating all hostkeys (ssh-keygen -A), clobber
625: existing keys if they exist but are zero length. zero-length keys
626: could previously be made if ssh-keygen failed or was interrupted part
627: way through generating them.
628: <li>ssh(1): fix pledge(2) violation in the escape sequence "~&" used to
629: place the current session in the background.
630: <li>ssh-keyscan(1): avoid double-close() on file descriptors.
631: <li>sshd(8): avoid reliance on shared use of pointers shared between
632: monitor and child sshd processes.
633: <li>sshd_config(8): document available AuthenticationMethods.
634: <li>ssh(1): avoid truncation in some login prompts.
635: <li>ssh(1): make "--" before the hostname terminate argument processing
636: after the hostname too.
637: <li>ssh-keygen(1): switch from aes256-cbc to aes256-ctr for encrypting
638: new-style private keys. Fixes problems related to private key
639: handling for no-OpenSSL builds.
640: <li>ssh(1): warn and do not attempt to use keys when the public and
641: private halves do not match.
642: <li>sftp(1): don't print verbose error message when ssh disconnects
643: from under sftp.
644: <li>sshd(8): fix keepalive scheduling problem: activity on a forwarded
645: port from preventing the keepalive from being sent.
646: <li>sshd(8): when started without root privileges, don't require the
647: privilege separation user or path to exist. Makes running the
648: regression tests easier without touching the filesystem.
649: <li>Make integrity.sh regression tests more robust against timeouts.
650: <li>ssh(1)/sshd(8): correctness fix for channels implementation: accept
651: channel IDs greater than 0x7FFFFFFF.

700: certificates (which it seems are common place with
701: openvpn/easyrsa) were also being included in this category.
702: <li>Added a new TLS extension handling framework and converted all
703: TLS extensions to use it.
704: <li>Improved and added many new manpages. Updated
705: <a href="https://man.openbsd.org/SSL_CTX_check_private_key.3">SSL_{CTX_,}check_private_key(3)</a>
706: manpages with additional cautions regarding their use.
707: <li>Cleaned up and simplified EC key/curve configuration handling.
708: <li>Added
709: <a href="https://man.openbsd.org/tls_config_set_ecdhecurves.3">tls_config_set_ecdhecurves(3)</a>
710: to libtls, which allows the names of the elliptical curves that may
711: be used during client and server key exchange to be specified.
712: <li>Converted more code paths to use CBB/CBS.
713: <li>Removed NPN support - NPN was never standardised and the last draft
714: expired in October 2012.
715: <li>Removed SSL_OP_CRYPTOPRO_TLSEXT_BUG workaround for old/broken
716: CryptoPro clients.
717: <li>Removed support for the TLS padding extension, which was added as a
1.60 jsing 718: workaround for an old bug in F5's TLS termination.
1.65 rob 719: <li>Added ability to clamp notafter values in certificates for systems
1.58 jsing 720: with 32-bit time_t. This is necessary to conform to RFC 5280 4.1.2.5.
721: <li>Removed the original (pre-IETF) chacha20-poly1305 cipher suites.
722: <li>Reclassified ECDHE-RSA-DES-CBC3-SHA from HIGH to MEDIUM.
723: <li>Provide a useful error with libtls if there are no OCSP URLs in a
724: peer certificate.
725: <li>Keep track of which keypair is in use by a TLS context, fixing a bug
726: where a TLS server with SNI would only return the OCSP staple for the
727: default keypair.
728: <li>If
729: <a href="https://man.openbsd.org/tls_config_parse_protocols.3">tls_config_parse_protocols(3)</a>
730: is called with a NULL pointer it now
731: returns the default protocols.

1110:
1111: <tt>sys.tar.gz</tt> contains a source archive starting at <tt>/usr/src/sys</tt>.
1112: This file contains all the kernel sources you need to rebuild kernels.
1113: To extract:
1114:
1115: <blockquote><pre>
1116: # <b>mkdir -p /usr/src/sys</b>
1117: # <b>cd /usr/src</b>
1118: # <b>tar xvfz /tmp/sys.tar.gz</b>
1119: </pre></blockquote>

1121: Both of these trees are a regular CVS checkout. Using these trees it
1122: is possible to get a head-start on using the anoncvs servers as
1123: described <a href="anoncvs.html">here</a>.
1124: Using these files
1125: results in a much faster initial CVS update than you could expect from
1126: a fresh checkout of the full OpenBSD source tree.

1133: A ports tree archive is also provided. To extract:
1134:
1135: <blockquote><pre>

1140: Go read the <a href="faq/ports/index.html">ports</a> page
1141: if you know nothing about ports
1142: at this point. This text is not a manual of how to use ports.
1143: Rather, it is a set of notes meant to kickstart the user on the
1144: OpenBSD ports system.
1145: <p>
1146: The <i>ports/</i> directory represents a CVS checkout of our ports.
1147: As with our complete source tree, our ports tree is available via
1148: <a href="anoncvs.html">AnonCVS</a>.
1149: So, in order to keep up to date with the <i>-stable</i> branch, you must make
1150: the <i>ports/</i> tree available on a read-write medium and update the tree
1151: with a command like:
1152:
1153: <blockquote><pre>
1154: # <b>cd /usr/ports</b>
1.15 phessler 1155: # <b>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_6_2</b>
1.1 deraadt 1156: </pre></blockquote>
1157:
1158: [Of course, you must replace the server name here with a nearby anoncvs
1159: server.]
1160: <p>
1161: Note that most ports are available as packages on our mirrors. Updated
1162: ports for the 6.2 release will be made available if problems arise.
1163: <p>
1164: If you're interested in seeing a port added, would like to help out, or just
1165: would like to know more, the mailing list
1166: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
