113:
114: <li>Various bugfixes and tweaks in userland:
115: <ul>
1.11 benno 116: <li>Refactoring and documenting of fdisk(8) code, to make the code
117: easier to maintain.
118: <li>In clang, allow out-of-class defaulting of comparison operators,
119: by ways of backporting an upstream commit.
120: <li>Improve the code of aucat(1) and fix spelling mistakes.
121: <li>Improve the code quality of find(1).
122: <li>Many changes in mg(1):
123: <ul>

148: when the voltage/current for a regulator is changed or when the
149: regulator gets initialized when it attaches for the first time. The
150: latter makes it possible to register a notifier for a regulator that

1.11 benno 226: <li>Make dig(1) use less deprecated LibreSSL API.
227: <li>In ypldap(8), reduce memory usage when updating larger directories.
1.1 deraadt 228: </ul>
229:
230: <li><a href="https://man.openbsd.org/tmux.1">tmux(1)</a> improvements and bug fixes:
231: <ul>
1.11 benno 232: <li>For passthrough, don't write to clients attached to different sessions.
233: <li>Add a format to show if there are unseen changes while in a mode.
1.1 deraadt 234: </ul>
235:
1.7 tb 236: <li>LibreSSL version 3.8.2
1.1 deraadt 237: <ul>
1.7 tb 238: <li>Security fixes
239: <ul>
240: <li>Disabled TLSv1.0 and TLSv1.1 in libssl so that they may no longer
241: be selected for use.
242: <li>BN_is_prime{,_fasttest}_ex() refuse to check numbers larger than
243: 32 kbits for primality. This mitigates various DoS vectors.
244: <li>Restricted the RFC 3779 code to IPv4 and IPv6. It was not written
245: to be able to deal with anything else.
246: </ul>
247: <li>Portable changes
248: <ul>
249: <li>Extended the endian.h compat header with hto* and *toh macros.
250: <li>Adapted more tests to the portable framework.
251: <li>Internal tools are now statically linked.
252: <li>Applications bundled as part of the LibreSSL package internally,
253: nc(1) and openssl(1), now are linked statically if static libraries
254: are built.
255: <li>Internal compatibility function symbols are no longer exported from
256: libcrypto. Instead, the libcompat library is linked to libcrypto,
257: libssl, and libtls separately. This increases size a little, but
258: ensures that the libraries are not exporting symbols to programs
259: unintentionally.
260: <li>Selective removal of CET implementation on platforms where it is
261: not supported (macOS).
262: <li>Integrated four more tests.
263: <li>Added Windows ARM64 architecture to tested platforms.
264: <li>Removed Solaris 10 support, fixed Solaris 11.
265: <li>libtls no longer links statically to libcrypto / libssl unless
266: <code>--enable-libtls-only</code> is specified at configure time.
267: <li>Improved Windows compatibility library, namely handling of files vs
268: sockets, correcting an exception when operating on a closed socket.
269: <li>CMake builds no longer hardcode <code>-O2</code> into the compiler flags,
270: instead using flags from the CMake build type instead.
271: <li>Set the CMake default build type to <code>Release</code>. This can be overridden
272: during configuration.
273: <li>Fixed broken ASM support with MinGW builds.
274: </ul>
1.1 deraadt 275: <li>New features
276: <ul>
1.7 tb 277: <li>Added support for truncated SHA-2 and for SHA-3.
278: <li>The BPSW primality test performs additional Miller-Rabin rounds
279: with random bases to reduce the likelihood of composites passing.
280: <li>Allow testing of ciphers and digests using badly aligned buffers
281: in openssl speed using -unalign.
282: <li>Ed25519 certificates are now supported in openssl(1) ca and req.
283: Prepared Ed25519 support in libssl.
284: <li>Add branch target information (BTI) support to amd64 and arm64
285: assembly.
1.1 deraadt 286: </ul>
287: <li>Compatibility changes
288: <ul>
1.7 tb 289: <li>Added a workaround for a poorly thought-out change in OpenSSL 3 that
290: broke privilege separation support in libtls.
291: <li>Moved libtls from ECDSA_METHOD to EC_KEY_METHOD.
292: <li>Removed GF2m support: BIGNUM no longer supports binary extension
293: field arithmetic and all binary elliptic builtin curves were removed.
294: <li>Removed dangerous, "fast" NIST prime and elliptic curve implementations.
295: In particular, EC_GFp_nist_method() is no longer available.
296: <li>Removed most public symbols that were deprecated in OpenSSL 0.9.8.
297: <li>Removed the public X9.31 API (RSA_X931_PADDING is still available).
298: <li>Removed Cipher Text Stealing mode.
299: <li>Removed ENGINE support, including ECDH_METHOD and ECDSA_METHOD.
300: <li>Removed COMP, DSO, dynamic loading of conf modules and support for
301: custom ex_data and error stacks.
302: <li>Removed proxy certificate (RFC 3820) support.
303: <li>Removed SXNET and NETSCAPE_CERT_SEQUENCE support including the
1.8 tb 304: openssl(1) nseq command.
1.7 tb 305: <li>ENGINE support was removed and OPENSSL_NO_ENGINE is set. In spite
306: of this, some stub functions are provided to avoid patching some
307: applications that do not honor OPENSSL_NO_ENGINE.
308: <li>The POLICY_TREE and its related structures and API were removed.
309: <li>In X509_VERIFY_PARAM_inherit() copy hostflags independently of the
310: host list.
311: <li>Made CRYPTO_get_ex_new_index() not return 0 to allow applications
312: to use *_{get,set}_app_data() and *_{get,set}_ex_data() alongside
313: each other.
314: <li>X509_NAME_get_text_by_{NID,OBJ}() now only succeed if they contain
315: valid UTF-8 without embedded NUL.
316: <li>The explicitText user notice uses UTF8String instead of VisibleString
317: to reduce the risk of emitting certificates with invalid DER-encoding.
318: <li>Initial fixes for RSA-PSS support to make the TLSv1.3 stack more
319: compliant with RFC 8446.
320: <li>Fixed EVP_CIPHER_CTX_iv_length() to return what was set with
321: EVP_CTRL_AEAD_SET_IVLEN or one of its aliases.
1.1 deraadt 322: </ul>
1.7 tb 323: <li>Internal improvements
1.1 deraadt 324: <ul>
1.7 tb 325: <li>Improved sieve of Eratosthenes script used for generating a table
326: of small primes.
327: <li>Removed incomplete and dangerous BN_RECURSION code.
328: <li>Imported RFC 5280 policy checking code from BoringSSL and used it
329: to replace the old exponential time code.
330: <li>Converted more of libcrypto to use CBB/CBS.
331: <li>Started cleaning up and rewriting SHA internals.
332: <li>Reduced the dependency of hash implementations on many layers of
333: macros. This results in significant speedups since modern compilers

368: <li>Ensure Montgomery exponentiation is used for the initial RSA blinding.
369: <li>Policy is always checked in X509 validation. Critical policy extensions
370: are no longer silently ignored.
371: <li>Fixed error handling in tls_check_common_name().
372: <li>Add missing pointer invalidation in SSL_free().
373: <li>Fixed X509err() and X509V3err() and their internal versions.
374: <li>Ensure that OBJ_obj2txt() always returns a C string again.
375: <li>Made EVP_PKEY_set1_hkdf_key() fail on a NULL key.
376: <li>On socket errors in the poll loop, netcat could issue system calls
377: on invalidated file descriptors.

382: </ul>
383: <li>Documentation improvements
384: <ul>
385: <li>Improved documentation of BIO_ctrl(3), BIO_set_info_callback(3),

1.1 deraadt 402: <ul>
1.12 dtucker 403: <li>Potentially incompatible changes
1.1 deraadt 404: <ul>
1.12 dtucker 405: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
406: generate Ed25519 keys by default. Ed25519 public keys
407: are very convenient due to their small size. Ed25519 keys are
408: specified in RFC 8709 and OpenSSH has supported them since version 6.5
409: (January 2014).
410: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
411: the Subsystem directive now accurately preserves quoting of
412: subsystem commands and arguments. This may change behaviour for exotic
413: configurations, but the most common subsystem configuration
414: (sftp-server) is unlikely to be affected.
1.13 dtucker 415: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:
416: PKCS#11 modules must now be specified by their full
417: paths. Previously dlopen(3) could search for them in system
418: library directories.
1.1 deraadt 419: </ul>
1.12 dtucker 420: <li>New features
1.1 deraadt 421: <ul>
1.12 dtucker 422: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
423: add keystroke timing obfuscation to the client. This attempts
424: to hide inter-keystroke timings by sending interactive traffic at
425: fixed intervals (default: every 20ms) when there is only a small
426: amount of data being sent. It also sends fake "chaff" keystrokes for
427: a random interval after the last real keystroke. These are
428: controlled by a new ssh_config ObscureKeystrokeTiming keyword.
429: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
430: <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
431: Introduce a transport-level ping facility. This adds
432: a pair of SSH transport protocol messages SSH2_MSG_PING/PONG to
433: implement a ping capability. These messages use numbers in the "local
434: extensions" number space and are advertised using a "ping@openssh.com"
435: ext-info message with a string version number of "0".
1.13 dtucker 436: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
437: allow override of Subsystem directives in sshd Match blocks.
438: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
439: allow forwarding Unix Domain sockets via ssh -W.
440: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
441: add support for configuration tags to ssh(1).
442: This adds a ssh_config(5) "Tag" directive and corresponding
443: "Match tag" predicate that may be used to select blocks of
444: configuration similar to the pf.conf(5) keywords of the same
445: name.
446: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
447: add a "match localnetwork" predicate. This allows matching
448: on the addresses of available network interfaces and may be used to
449: vary the effective client configuration based on network location.

454: extensions. This defines wire formats for optional KRL extensions
455: and implements parsing of the new submessages. No actual extensions
456: are supported at this point.
457: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
458: AuthorizedPrincipalsCommand and AuthorizedKeysCommand now
459: accept two additional %-expansion sequences: %D which expands to
460: the routing domain of the connected session and %C which expands
461: to the addresses and port numbers for the source and destination
462: of the connection.
463: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
464: increase the default work factor (rounds) for the
465: bcrypt KDF used to derive symmetric encryption keys for passphrase
466: protected key files by 50%.

469: <ul>
1.12 dtucker 470: <li><a href="https://man.openbsd.org/scp.1">scp(1)</a>:
471: fix scp in SFTP mode recursive upload and download of
472: directories that contain symlinks to other directories. In scp mode,
473: the links would be followed, but in SFTP mode they were not.
474: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
475: handle cr+lf (instead of just cr) line endings in
476: sshsig signature files.
477: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
478: interactive mode for ControlPersist sessions if they
479: originally requested a tty.
480: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
481: make PerSourceMaxStartups first-match-wins
482: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
483: limit artificial login delay to a reasonable maximum (5s)
484: and don't delay at all for the "none" authentication mechanism.
1.13 dtucker 485: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
486: Log errors in kex_exchange_identification() with level
1.12 dtucker 487: verbose instead of error to reduce preauth log spam. All of those
488: get logged with a more generic error message by sshpkt_fatal().
489: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
490: correct math for ClientAliveInterval that caused the probes
491: to be sent less frequently than configured.
1.13 dtucker 492: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:

497: multiplexed connections, including ControlPersist.
498: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
499: make ConnectTimeout apply to multiplexing sockets and not

505: contains the required symbol before loading it.
506: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
507: fix AuthorizedPrincipalsCommand when AuthorizedKeysCommand

510: this situation.

514: remove vestigal support for KRL
515: signatures When the KRL format was originally defined, it included
516: support for signing of KRL objects. However, the code to sign KRLs
517: and verify KRL signatues was never completed in OpenSSH. This
518: release removes the partially-implemented code to verify KRLs.
519: All OpenSSH tools now ignore KRL_SECTION_SIGNATURE sections in
520: KRL files.
521: <li>All: fix a number of memory leaks and unreachable/harmless integer

527: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
528: better validate CASignatureAlgorithms in
529: ssh_config and sshd_config. Previously this directive would accept
530: certificate algorithm names, but these were unusable in practice as
531: OpenSSH does not support CA chains.
532: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
533: make <code>ssh -Q CASignatureAlgorithms</code> only list signature
534: algorithms that are valid for CA signing. Previous behaviour was
535: to list all signing algorithms, including certificate algorithms.
536: <li><a href="https://man.openbsd.org/ssh-keyscan.1">ssh-keyscan(1)</a>:
537: gracefully handle systems where rlimits or the

547: the resultant file would be erroneously truncated.
548: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
549: don't incorrectly disable hostname canonicalization when

852: <h3>Notes about the source code</h3>
853: <p>
854: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
855: This file contains everything you need except for the kernel sources,
856: which are in a separate archive.
857: To extract:
858: <blockquote><pre>
859: # <kbd>mkdir -p /usr/src</kbd>
860: # <kbd>cd /usr/src</kbd>
861: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
862: </pre></blockquote>
863: <p>
864: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
865: This file contains all the kernel sources you need to rebuild kernels.
866: To extract:
867: <blockquote><pre>
868: # <kbd>mkdir -p /usr/src/sys</kbd>
869: # <kbd>cd /usr/src</kbd>
870: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
871: </pre></blockquote>
872: <p>
873: Both of these trees are a regular CVS checkout. Using these trees it
874: is possible to get a head-start on using the anoncvs servers as
875: described <a href="anoncvs.html">here</a>.
876: Using these files
877: results in a much faster initial CVS update than you could expect from
878: a fresh checkout of the full OpenBSD source tree.

884: <h3>Ports Tree</h3>
885: <p>
886: A ports tree archive is also provided. To extract:
887: <blockquote><pre>
888: # <kbd>cd /usr</kbd>
889: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
890: </pre></blockquote>
891: <p>
892: Go read the <a href="faq/ports/index.html">ports</a> page
893: if you know nothing about ports
894: at this point. This text is not a manual of how to use ports.
895: Rather, it is a set of notes meant to kickstart the user on the
896: OpenBSD ports system.
897: <p>
898: The <i>ports/</i> directory represents a CVS checkout of our ports.
899: As with our complete source tree, our ports tree is available via
900: <a href="anoncvs.html">AnonCVS</a>.
901: So, in order to keep up to date with the -stable branch, you must make
902: the <i>ports/</i> tree available on a read-write medium and update the tree
903: with a command like:
904: <blockquote><pre>
905: # <kbd>cd /usr/ports</kbd>
1.2 jsg 906: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_4</kbd>
1.1 deraadt 907: </pre></blockquote>
908: <p>
909: [Of course, you must replace the server name here with a nearby anoncvs
910: server.]
911: <p>
912: Note that most ports are available as packages on our mirrors. Updated
913: ports for the 7.4 release will be made available if problems arise.
914: <p>
915: If you're interested in seeing a port added, would like to help out, or just
916: would like to know more, the mailing list
917: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
