460:
1.22 jsg 461: <li>OpenSSH 7.7
1.1 deraadt 462: <ul>
463: <li>New/changed features:
464: <ul>
1.47 deraadt 465: <li>All: Add experimental support for PQC XMSS keys (Extended Hash-
466: Based Signatures) based on the algorithm described in
467: https://tools.ietf.org/html/draft-irtf-cfrg-xmss-hash-based-signatures-12
468: The XMSS signature code is experimental and not compiled in by
469: default.
470: <li>sshd(8): Add a "rdomain" criteria for the sshd_config Match keyword
471: to allow conditional configuration that depends on which routing
472: domain a connection was received on (currently supported on OpenBSD
473: and Linux).
474: <li>sshd_config(5): Add an optional rdomain qualifier to the
475: ListenAddress directive to allow listening on different routing
476: domains. This is supported only on OpenBSD and Linux at present.
477: <li>sshd_config(5): Add RDomain directive to allow the authenticated
478: session to be placed in an explicit routing domain. This is only
479: supported on OpenBSD at present.
480: <li>sshd(8): Add "expiry-time" option for authorized_keys files to
481: allow for expiring keys.
482: <li>ssh(1): Add a BindInterface option to allow binding the outgoing
483: connection to an interface's address (basically a more usable
1.50 jsg 484: BindAddress).
1.47 deraadt 485: <li>ssh(1): Expose device allocated for tun/tap forwarding via a new
486: %T expansion for LocalCommand. This allows LocalCommand to be used
487: to prepare the interface.
488: <li>sshd(8): Expose the device allocated for tun/tap forwarding via a
489: new SSH_TUNNEL environment variable. This allows automatic setup of
490: the interface and surrounding network configuration automatically on
491: the server.
492: <li>ssh(1)/scp(1)/sftp(1): Add URI support to ssh, sftp and scp, e.g.
493: ssh://user@host or sftp://user@host/path. Additional connection
494: parameters described in draft-ietf-secsh-scp-sftp-ssh-uri-04 are not
495: implemented since the ssh fingerprint format in the draft uses the
496: deprecated MD5 hash with no way to specify the any other algorithm.
497: <li>ssh-keygen(1): Allow certificate validity intervals that specify
498: only a start or stop time (instead of both or neither).
499: <li>sftp(1): Allow "cd" and "lcd" commands with no explicit path
500: argument. lcd will change to the local user's home directory as
501: usual. cd will change to the starting directory for session (because
502: the protocol offers no way to obtain the remote user's home
503: directory). bz#2760
504: <li>sshd(8): When doing a config test with sshd -T, only require the
505: attributes that are actually used in Match criteria rather than (an
506: incomplete list of) all criteria.
1.1 deraadt 507: </ul>
508: <li>The following significant bugs have been fixed in this release:
509: <ul>
1.47 deraadt 510: <li>ssh(1)/sshd(8): More strictly check signature types during key
511: exchange against what was negotiated. Prevents downgrade of RSA
512: signatures made with SHA-256/512 to SHA-1.
513: <li>sshd(8): Fix support for client that advertise a protocol version
514: of "1.99" (indicating that they are prepared to accept both SSHv1 and
515: SSHv2). This was broken in OpenSSH 7.6 during the removal of SSHv1
516: support. bz#2810
517: <li>ssh(1): Warn when the agent returns a ssh-rsa (SHA1) signature when
518: a rsa-sha2-256/512 signature was requested. This condition is possible
519: when an old or non-OpenSSH agent is in use. bz#2799
520: <li>ssh-agent(1): Fix regression introduce in 7.6 that caused ssh-agent
521: to fatally exit if presented an invalid signature request message.
522: <li>sshd_config(5): Accept yes/no flag options case-insensitively, as
523: has been the case in ssh_config(5) for a long time. bz#2664
524: <li>ssh(1): Improve error reporting for failures during connection.
525: Under some circumstances misleading errors were being shows. bz#2814
526: <li>ssh-keyscan(1): Add -D option to allow printing of results directly
527: in SSHFP format. bz#2821
528: <li>regress tests: fix PuTTY interop test broken in last release's SSHv1
529: removal. bz#2823
530: <li>ssh(1): Compatibility fix for some servers that erroneously drop the
531: connection when the IUTF8 (RFC8160) option is sent.
532: <li>scp(1): Disable RemoteCommand and RequestTTY in the ssh session
533: started by scp (sftp was already doing this.)
534: <li>ssh-keygen(1): Refuse to create a certificate with an unusable
535: number of principals.
536: <li>ssh-keygen(1): Fatally exit if ssh-keygen is unable to write all the
537: public key during key generation. Previously it would silently
538: ignore errors writing the comment and terminating newline.
539: <li>ssh(1): Do not modify hostname arguments that are addresses by
540: automatically forcing them to lower-case. Instead canonicalise them
541: to resolve ambiguities (e.g. ::0001 => ::1) before they are matched
542: against known_hosts. bz#2763
543: <li>ssh(1): Don't accept junk after "yes" or "no" responses to hostkey
544: prompts. bz#2803
545: <li>sftp(1): Have sftp print a warning about shell cleanliness when
546: decoding the first packet fails, which is usually caused by shells
547: polluting stdout of non-interactive startups. bz#2800
548: <li>ssh(1)/sshd(8): Switch timers in packet code from using wall-clock
549: time to monotonic time, allowing the packet layer to better function
550: over a clock step and avoiding possible integer overflows during
551: steps.
552: <li>Numerous manual page fixes and improvements.
1.1 deraadt 553: </ul>
554: </ul>
555: <p>
556:
1.22 jsg 557: <li>LibreSSL 2.7.2
1.29 beck 558: <ul>
559: <li> Added support for many OpenSSL 1.0.2 and 1.1 APIs, based on
560: observations of real-world usage in applications. These are
561: implemented in parallel with existing OpenSSL 1.0.1 APIs - visibility
562: changes have not been made to existing structs, allowing code written
563: for older OpenSSL APIs to continue working.
564: <li> Extensive corrections, improvements, and additions to the
565: API documentation, including new public APIs from OpenSSL that had
566: no pre-existing documentation.
567: <li> Added support for automatic library initialization in libcrypto,
568: libssl, and libtls. Support for pthread_once or a compatible
569: equivalent is now required of the target operating system. As a
570: side-effect, minimum Windows support is Vista or higher.
571: <li> Converted more packet handling methods to CBB, which improves
572: resiliency when generating TLS messages.
573: <li> Completed TLS extension handling rewrite, improving consistency of
574: checks for malformed and duplicate extensions.
575: <li>Rewrote ASN1_TYPE_{get,set}_octetstring() using templated ASN.1.
576: This removes the last remaining use of the old M_ASN1_* macros
577: (asn1_mac.h) from API that needs to continue to exist.
578: <li> Added support for client-side session resumption in libtls.
579: A libtls client can specify a session file descriptor (a regular
580: file with appropriate ownership and permissions) and libtls will
581: manage reading and writing of session data across TLS handshakes.
582: <li> Improved support for strict alignment on ARMv7 architectures,
583: conditionally enabling assembly in those cases.
584: <li> Fixed a memory leak in libtls when reusing a tls_config.
585: <li> Merged more DTLS support into the regular TLS code path, removing
586: duplicated code.

922: This file contains everything you need except for the kernel sources,

924: To extract:
925:
926: <blockquote><pre>
927: # <b>mkdir -p /usr/src</b>
928: # <b>cd /usr/src</b>
929: # <b>tar xvfz /tmp/src.tar.gz</b>
930: </pre></blockquote>
931:
932: <tt>sys.tar.gz</tt> contains a source archive starting at <tt>/usr/src/sys</tt>.
933: This file contains all the kernel sources you need to rebuild kernels.
934: To extract:

961: Go read the <a href="faq/ports/index.html">ports</a> page
962: if you know nothing about ports
963: at this point. This text is not a manual of how to use ports.
964: Rather, it is a set of notes meant to kickstart the user on the
965: OpenBSD ports system.
966: <p>
967: The <i>ports/</i> directory represents a CVS checkout of our ports.
968: As with our complete source tree, our ports tree is available via
969: <a href="anoncvs.html">AnonCVS</a>.
970: So, in order to keep up to date with the -stable branch, you must make
971: the <i>ports/</i> tree available on a read-write medium and update the tree
972: with a command like:
973:
974: <blockquote><pre>
975: # <b>cd /usr/ports</b>
976: # <b>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_6_3</b>
977: </pre></blockquote>
978:
979: [Of course, you must replace the server name here with a nearby anoncvs
980: server.]
981: <p>
982: Note that most ports are available as packages on our mirrors. Updated
983: ports for the 6.3 release will be made available if problems arise.
984: <p>
985: If you're interested in seeing a port added, would like to help out, or just
986: would like to know more, the mailing list
987: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
