325:
1.7 tb 326: <li>LibreSSL version 3.8.2
1.1 deraadt 327: <ul>
1.7 tb 328: <li>Security fixes
329: <ul>
330: <li>Disabled TLSv1.0 and TLSv1.1 in libssl so that they may no longer
331: be selected for use.
332: <li>BN_is_prime{,_fasttest}_ex() refuse to check numbers larger than
333: 32 kbits for primality. This mitigates various DoS vectors.
334: <li>Restricted the RFC 3779 code to IPv4 and IPv6. It was not written
335: to be able to deal with anything else.
336: </ul>
337: <li>Portable changes
338: <ul>
339: <li>Extended the endian.h compat header with hto* and *toh macros.
340: <li>Adapted more tests to the portable framework.
341: <li>Internal tools are now statically linked.
342: <li>Applications bundled as part of the LibreSSL package internally,
343: nc(1) and openssl(1), now are linked statically if static libraries
344: are built.
345: <li>Internal compatibility function symbols are no longer exported from
346: libcrypto. Instead, the libcompat library is linked to libcrypto,
347: libssl, and libtls separately. This increases size a little, but
348: ensures that the libraries are not exporting symbols to programs
349: unintentionally.
350: <li>Selective removal of CET implementation on platforms where it is
351: not supported (macOS).
352: <li>Integrated four more tests.
353: <li>Added Windows ARM64 architecture to tested platforms.
354: <li>Removed Solaris 10 support, fixed Solaris 11.
355: <li>libtls no longer links statically to libcrypto / libssl unless
356: <code>--enable-libtls-only</code> is specified at configure time.
357: <li>Improved Windows compatibility library, namely handling of files vs
358: sockets, correcting an exception when operating on a closed socket.
359: <li>CMake builds no longer hardcode <code>-O2</code> into the compiler flags,
360: instead using flags from the CMake build type instead.
361: <li>Set the CMake default build type to <code>Release</code>. This can be overridden
362: during configuration.
363: <li>Fixed broken ASM support with MinGW builds.
364: </ul>
1.1 deraadt 365: <li>New features
366: <ul>
1.7 tb 367: <li>Added support for truncated SHA-2 and for SHA-3.
368: <li>The BPSW primality test performs additional Miller-Rabin rounds
369: with random bases to reduce the likelihood of composites passing.
370: <li>Allow testing of ciphers and digests using badly aligned buffers
371: in openssl speed using -unalign.
372: <li>Ed25519 certificates are now supported in openssl(1) ca and req.
373: Prepared Ed25519 support in libssl.
374: <li>Add branch target information (BTI) support to amd64 and arm64
375: assembly.
1.1 deraadt 376: </ul>
377: <li>Compatibility changes
378: <ul>
1.7 tb 379: <li>Added a workaround for a poorly thought-out change in OpenSSL 3 that
380: broke privilege separation support in libtls.
381: <li>Moved libtls from ECDSA_METHOD to EC_KEY_METHOD.
382: <li>Removed GF2m support: BIGNUM no longer supports binary extension
383: field arithmetic and all binary elliptic builtin curves were removed.
384: <li>Removed dangerous, "fast" NIST prime and elliptic curve implementations.
385: In particular, EC_GFp_nist_method() is no longer available.
386: <li>Removed most public symbols that were deprecated in OpenSSL 0.9.8.
387: <li>Removed the public X9.31 API (RSA_X931_PADDING is still available).
388: <li>Removed Cipher Text Stealing mode.
389: <li>Removed ENGINE support, including ECDH_METHOD and ECDSA_METHOD.
390: <li>Removed COMP, DSO, dynamic loading of conf modules and support for
391: custom ex_data and error stacks.
392: <li>Removed proxy certificate (RFC 3820) support.
393: <li>Removed SXNET and NETSCAPE_CERT_SEQUENCE support including the
1.8 tb 394: openssl(1) nseq command.
1.7 tb 395: <li>ENGINE support was removed and OPENSSL_NO_ENGINE is set. In spite
396: of this, some stub functions are provided to avoid patching some
397: applications that do not honor OPENSSL_NO_ENGINE.
398: <li>The POLICY_TREE and its related structures and API were removed.

1.12 dtucker 493: <li>Potentially incompatible changes
1.1 deraadt 494: <ul>
1.12 dtucker 495: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
496: generate Ed25519 keys by default. Ed25519 public keys
497: are very convenient due to their small size. Ed25519 keys are
498: specified in RFC 8709 and OpenSSH has supported them since version 6.5
499: (January 2014).
500: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
501: the Subsystem directive now accurately preserves quoting of
502: subsystem commands and arguments. This may change behaviour for exotic
503: configurations, but the most common subsystem configuration
504: (sftp-server) is unlikely to be affected.
1.13 dtucker 505: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:
506: PKCS#11 modules must now be specified by their full
507: paths. Previously dlopen(3) could search for them in system
508: library directories.
1.1 deraadt 509: </ul>
1.12 dtucker 510: <li>New features
1.1 deraadt 511: <ul>
1.12 dtucker 512: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
513: add keystroke timing obfuscation to the client. This attempts
514: to hide inter-keystroke timings by sending interactive traffic at
515: fixed intervals (default: every 20ms) when there is only a small
516: amount of data being sent. It also sends fake "chaff" keystrokes for
517: a random interval after the last real keystroke. These are
518: controlled by a new ssh_config ObscureKeystrokeTiming keyword.
519: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
520: <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
521: Introduce a transport-level ping facility. This adds
522: a pair of SSH transport protocol messages SSH2_MSG_PING/PONG to
523: implement a ping capability. These messages use numbers in the "local
524: extensions" number space and are advertised using a "ping@openssh.com"
525: ext-info message with a string version number of "0".
1.13 dtucker 526: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
527: allow override of Subsystem directives in sshd Match blocks.
528: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
529: allow forwarding Unix Domain sockets via ssh -W.
530: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
531: add support for configuration tags to ssh(1).
532: This adds a ssh_config(5) "Tag" directive and corresponding
533: "Match tag" predicate that may be used to select blocks of
534: configuration similar to the pf.conf(5) keywords of the same
535: name.
536: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
537: add a "match localnetwork" predicate. This allows matching
538: on the addresses of available network interfaces and may be used to
539: vary the effective client configuration based on network location.
540: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
541: <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>,
542: <a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
543: infrastructure support for KRL
544: extensions. This defines wire formats for optional KRL extensions
545: and implements parsing of the new submessages. No actual extensions
546: are supported at this point.
547: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
548: AuthorizedPrincipalsCommand and AuthorizedKeysCommand now
549: accept two additional %-expansion sequences: %D which expands to
550: the routing domain of the connected session and %C which expands
551: to the addresses and port numbers for the source and destination
552: of the connection.
553: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
554: increase the default work factor (rounds) for the
555: bcrypt KDF used to derive symmetric encryption keys for passphrase
556: protected key files by 50%.

558: <li>Bugfixes
559: <ul>
1.12 dtucker 560: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>:
561: fix scp in SFTP mode recursive upload and download of
562: directories that contain symlinks to other directories. In scp mode,
563: the links would be followed, but in SFTP mode they were not.
564: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
565: handle cr+lf (instead of just cr) line endings in
566: sshsig signature files.
567: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
568: interactive mode for ControlPersist sessions if they
569: originally requested a tty.
570: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
571: make PerSourceMaxStartups first-match-wins
572: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
573: limit artificial login delay to a reasonable maximum (5s)
574: and don't delay at all for the "none" authentication mechanism.
1.13 dtucker 575: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
576: Log errors in kex_exchange_identification() with level
1.12 dtucker 577: verbose instead of error to reduce preauth log spam. All of those
578: get logged with a more generic error message by sshpkt_fatal().
579: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
580: correct math for ClientAliveInterval that caused the probes
581: to be sent less frequently than configured.
1.13 dtucker 582: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:
583: improve isolation between loaded PKCS#11 modules
584: by running separate ssh-pkcs11-helpers for each loaded provider.
585: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
586: make -f (fork after authentication) work correctly with
587: multiplexed connections, including ControlPersist.
588: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
589: make ConnectTimeout apply to multiplexing sockets and not
590: just to network connections.
591: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>,
592: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
593: improve defences against invalid PKCS#11
594: modules being loaded by checking that the requested module
595: contains the required symbol before loading it.
596: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
597: fix AuthorizedPrincipalsCommand when AuthorizedKeysCommand
598: appears before it in sshd_config. Since OpenSSH 8.7 the
599: AuthorizedPrincipalsCommand directive was incorrectly ignored in
600: this situation.
601: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>,
602: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
603: <a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
1.16 jsg 604: remove vestigial support for KRL
1.13 dtucker 605: signatures When the KRL format was originally defined, it included
606: support for signing of KRL objects. However, the code to sign KRLs
1.16 jsg 607: and verify KRL signatures was never completed in OpenSSH. This
1.13 dtucker 608: release removes the partially-implemented code to verify KRLs.
609: All OpenSSH tools now ignore KRL_SECTION_SIGNATURE sections in
610: KRL files.
611: <li>All: fix a number of memory leaks and unreachable/harmless integer
612: overflows.
613: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>,
614: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
615: don't truncate strings logged from PKCS#11 modules
616: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>,
617: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
618: better validate CASignatureAlgorithms in
619: ssh_config and sshd_config. Previously this directive would accept
620: certificate algorithm names, but these were unusable in practice as
621: OpenSSH does not support CA chains.
622: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
623: make <code>ssh -Q CASignatureAlgorithms</code> only list signature
624: algorithms that are valid for CA signing. Previous behaviour was
625: to list all signing algorithms, including certificate algorithms.
626: <li><a href="https://man.openbsd.org/ssh-keyscan.1">ssh-keyscan(1)</a>:
627: gracefully handle systems where rlimits or the
628: maximum number of open files is larger than INT_MAX
629: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
630: fix "no comment" not showing on when running
631: <code>ssh-keygen -l</code> on multiple keys where one has a comment
632: and other following keys do not.
633: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>,
1.14 dtucker 634: <a href="https://man.openbsd.org/sftp.1">sftp(1)</a>:
1.13 dtucker 635: adjust ftruncate() logic to handle servers that
636: reorder requests. Previously, if the server reordered requests then
637: the resultant file would be erroneously truncated.
638: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
639: don't incorrectly disable hostname canonicalization when
1.16 jsg 640: CanonicalizeHostname=yes and ProxyJump was explicitly set to
1.13 dtucker 641: "none".
642: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>:
643: when copying local to remote, check that the source file

927: <h3>How to upgrade</h3>
928: <p>
1.3 jsg 929: If you already have an OpenBSD 7.3 system, and do not want to reinstall,
1.1 deraadt 930: upgrade instructions and advice can be found in the
931: <a href="faq/upgrade74.html">Upgrade Guide</a>.

936: <section id=sourcecode>
937: <h3>Notes about the source code</h3>
938: <p>
939: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
940: This file contains everything you need except for the kernel sources,
941: which are in a separate archive.
942: To extract:
943: <blockquote><pre>
944: # <kbd>mkdir -p /usr/src</kbd>
945: # <kbd>cd /usr/src</kbd>
946: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
947: </pre></blockquote>
948: <p>
949: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
950: This file contains all the kernel sources you need to rebuild kernels.
951: To extract:
952: <blockquote><pre>
953: # <kbd>mkdir -p /usr/src/sys</kbd>
954: # <kbd>cd /usr/src</kbd>
955: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
956: </pre></blockquote>
957: <p>
958: Both of these trees are a regular CVS checkout. Using these trees it
959: is possible to get a head-start on using the anoncvs servers as
960: described <a href="anoncvs.html">here</a>.
961: Using these files
962: results in a much faster initial CVS update than you could expect from
963: a fresh checkout of the full OpenBSD source tree.

968: <section id=ports>
969: <h3>Ports Tree</h3>
970: <p>
971: A ports tree archive is also provided. To extract:
972: <blockquote><pre>
973: # <kbd>cd /usr</kbd>
974: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
975: </pre></blockquote>
976: <p>
977: Go read the <a href="faq/ports/index.html">ports</a> page
978: if you know nothing about ports
979: at this point. This text is not a manual of how to use ports.
980: Rather, it is a set of notes meant to kickstart the user on the
981: OpenBSD ports system.
982: <p>
983: The <i>ports/</i> directory represents a CVS checkout of our ports.
984: As with our complete source tree, our ports tree is available via
985: <a href="anoncvs.html">AnonCVS</a>.
986: So, in order to keep up to date with the -stable branch, you must make
987: the <i>ports/</i> tree available on a read-write medium and update the tree
988: with a command like:
989: <blockquote><pre>
990: # <kbd>cd /usr/ports</kbd>
1.2 jsg 991: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_4</kbd>
1.1 deraadt 992: </pre></blockquote>
993: <p>
994: [Of course, you must replace the server name here with a nearby anoncvs
995: server.]
996: <p>
997: Note that most ports are available as packages on our mirrors. Updated
998: ports for the 7.4 release will be made available if problems arise.
999: <p>
1000: If you're interested in seeing a port added, would like to help out, or just
1001: would like to know more, the mailing list
1002: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
