1.22 jsg 422: <li>OpenSSH 7.7
1.1 deraadt 423: <ul>
424: <li>New/changed features:
425: <ul>
1.47 ! deraadt 426: <li>All: Add experimental support for PQC XMSS keys (Extended Hash-
! 427: Based Signatures) based on the algorithm described in
! 428: https://tools.ietf.org/html/draft-irtf-cfrg-xmss-hash-based-signatures-12
! 429: The XMSS signature code is experimental and not compiled in by
! 430: default.
! 431: <li>sshd(8): Add a "rdomain" criteria for the sshd_config Match keyword
! 432: to allow conditional configuration that depends on which routing
! 433: domain a connection was received on (currently supported on OpenBSD
! 434: and Linux).
! 435: <li>sshd_config(5): Add an optional rdomain qualifier to the
! 436: ListenAddress directive to allow listening on different routing
! 437: domains. This is supported only on OpenBSD and Linux at present.
! 438: <li>sshd_config(5): Add RDomain directive to allow the authenticated
! 439: session to be placed in an explicit routing domain. This is only
! 440: supported on OpenBSD at present.
! 441: <li>sshd(8): Add "expiry-time" option for authorized_keys files to
! 442: allow for expiring keys.
! 443: <li>ssh(1): Add a BindInterface option to allow binding the outgoing
! 444: connection to an interface's address (basically a more usable
! 445: BindAddress)
! 446: <li>ssh(1): Expose device allocated for tun/tap forwarding via a new
! 447: %T expansion for LocalCommand. This allows LocalCommand to be used
! 448: to prepare the interface.
! 449: <li>sshd(8): Expose the device allocated for tun/tap forwarding via a
! 450: new SSH_TUNNEL environment variable. This allows automatic setup of
! 451: the interface and surrounding network configuration automatically on
! 452: the server.
! 453: <li>ssh(1)/scp(1)/sftp(1): Add URI support to ssh, sftp and scp, e.g.
! 454: ssh://user@host or sftp://user@host/path. Additional connection
! 455: parameters described in draft-ietf-secsh-scp-sftp-ssh-uri-04 are not
! 456: implemented since the ssh fingerprint format in the draft uses the
! 457: deprecated MD5 hash with no way to specify the any other algorithm.
! 458: <li>ssh-keygen(1): Allow certificate validity intervals that specify
! 459: only a start or stop time (instead of both or neither).
! 460: <li>sftp(1): Allow "cd" and "lcd" commands with no explicit path
! 461: argument. lcd will change to the local user's home directory as
! 462: usual. cd will change to the starting directory for session (because
! 463: the protocol offers no way to obtain the remote user's home
! 464: directory). bz#2760
! 465: <li>sshd(8): When doing a config test with sshd -T, only require the
! 466: attributes that are actually used in Match criteria rather than (an
! 467: incomplete list of) all criteria.
1.1 deraadt 468: </ul>
469: <li>The following significant bugs have been fixed in this release:
470: <ul>
1.47 ! deraadt 471: <li>ssh(1)/sshd(8): More strictly check signature types during key
! 472: exchange against what was negotiated. Prevents downgrade of RSA
! 473: signatures made with SHA-256/512 to SHA-1.
! 474: <li>sshd(8): Fix support for client that advertise a protocol version
! 475: of "1.99" (indicating that they are prepared to accept both SSHv1 and
! 476: SSHv2). This was broken in OpenSSH 7.6 during the removal of SSHv1
! 477: support. bz#2810
! 478: <li>ssh(1): Warn when the agent returns a ssh-rsa (SHA1) signature when
! 479: a rsa-sha2-256/512 signature was requested. This condition is possible
! 480: when an old or non-OpenSSH agent is in use. bz#2799
! 481: <li>ssh-agent(1): Fix regression introduce in 7.6 that caused ssh-agent
! 482: to fatally exit if presented an invalid signature request message.
! 483: <li>sshd_config(5): Accept yes/no flag options case-insensitively, as
! 484: has been the case in ssh_config(5) for a long time. bz#2664
! 485: <li>ssh(1): Improve error reporting for failures during connection.
! 486: Under some circumstances misleading errors were being shows. bz#2814
! 487: <li>ssh-keyscan(1): Add -D option to allow printing of results directly
! 488: in SSHFP format. bz#2821
! 489: <li>regress tests: fix PuTTY interop test broken in last release's SSHv1
! 490: removal. bz#2823
! 491: <li>ssh(1): Compatibility fix for some servers that erroneously drop the
! 492: connection when the IUTF8 (RFC8160) option is sent.
! 493: <li>scp(1): Disable RemoteCommand and RequestTTY in the ssh session
! 494: started by scp (sftp was already doing this.)
! 495: <li>ssh-keygen(1): Refuse to create a certificate with an unusable
! 496: number of principals.
! 497: <li>ssh-keygen(1): Fatally exit if ssh-keygen is unable to write all the
! 498: public key during key generation. Previously it would silently
! 499: ignore errors writing the comment and terminating newline.
! 500: <li>ssh(1): Do not modify hostname arguments that are addresses by
! 501: automatically forcing them to lower-case. Instead canonicalise them
! 502: to resolve ambiguities (e.g. ::0001 => ::1) before they are matched
! 503: against known_hosts. bz#2763
! 504: <li>ssh(1): Don't accept junk after "yes" or "no" responses to hostkey
! 505: prompts. bz#2803
! 506: <li>sftp(1): Have sftp print a warning about shell cleanliness when
! 507: decoding the first packet fails, which is usually caused by shells
! 508: polluting stdout of non-interactive startups. bz#2800
! 509: <li>ssh(1)/sshd(8): Switch timers in packet code from using wall-clock
! 510: time to monotonic time, allowing the packet layer to better function
! 511: over a clock step and avoiding possible integer overflows during
! 512: steps.
! 513: <li>Numerous manual page fixes and improvements.
1.1 deraadt 514: </ul>
515: </ul>
516: <p>
517:
1.22 jsg 518: <li>LibreSSL 2.7.2
1.29 beck 519: <ul>
520: <li> Fixed a bug in int_x509_param_set_hosts, calling strlen() if name
521: length provided is 0 to match the OpenSSL behaviour. Issue noticed
1.45 jsg 522: by Christian Heimes <christian@python.org>.
1.29 beck 523: <li> Added support for many OpenSSL 1.0.2 and 1.1 APIs, based on
524: observations of real-world usage in applications. These are
525: implemented in parallel with existing OpenSSL 1.0.1 APIs - visibility
526: changes have not been made to existing structs, allowing code written
527: for older OpenSSL APIs to continue working.
528: <li> Extensive corrections, improvements, and additions to the
529: API documentation, including new public APIs from OpenSSL that had
530: no pre-existing documentation.
531: <li> Added support for automatic library initialization in libcrypto,
532: libssl, and libtls. Support for pthread_once or a compatible
533: equivalent is now required of the target operating system. As a
534: side-effect, minimum Windows support is Vista or higher.
535: <li> Converted more packet handling methods to CBB, which improves
536: resiliency when generating TLS messages.
537: <li> Completed TLS extension handling rewrite, improving consistency of
538: checks for malformed and duplicate extensions.
539: <li>Rewrote ASN1_TYPE_{get,set}_octetstring() using templated ASN.1.
540: This removes the last remaining use of the old M_ASN1_* macros
541: (asn1_mac.h) from API that needs to continue to exist.
542: <li> Added support for client-side session resumption in libtls.
543: A libtls client can specify a session file descriptor (a regular
544: file with appropriate ownership and permissions) and libtls will
545: manage reading and writing of session data across TLS handshakes.
546: <li> Improved support for strict alignment on ARMv7 architectures,
547: conditionally enabling assembly in those cases.
548: <li> Fixed a memory leak in libtls when reusing a tls_config.
549: <li> Merged more DTLS support into the regular TLS code path, removing
550: duplicated code.

882: To extract:
883:
884: <blockquote><pre>
885: # <b>mkdir -p /usr/src</b>
886: # <b>cd /usr/src</b>
887: # <b>tar xvfz /tmp/src.tar.gz</b>

890: <tt>sys.tar.gz</tt> contains a source archive starting at <tt>/usr/src/sys</tt>.

919: Go read the <a href="faq/ports/index.html">ports</a> page
920: if you know nothing about ports
921: at this point. This text is not a manual of how to use ports.
922: Rather, it is a set of notes meant to kickstart the user on the
923: OpenBSD ports system.
924: <p>
925: The <i>ports/</i> directory represents a CVS checkout of our ports.
926: As with our complete source tree, our ports tree is available via
927: <a href="anoncvs.html">AnonCVS</a>.
928: So, in order to keep up to date with the -stable branch, you must make
929: the <i>ports/</i> tree available on a read-write medium and update the tree
930: with a command like:
931:
932: <blockquote><pre>
933: # <b>cd /usr/ports</b>
934: # <b>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_6_3</b>
935: </pre></blockquote>
936:
937: [Of course, you must replace the server name here with a nearby anoncvs
938: server.]
939: <p>
940: Note that most ports are available as packages on our mirrors. Updated
941: ports for the 6.3 release will be made available if problems arise.
942: <p>
943: If you're interested in seeing a port added, would like to help out, or just
944: would like to know more, the mailing list
945: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
