616: <li>File modification timestamps of objects retrieved via RRDP are now
617: deterministically set to prepare the on-disk cache for seamless
618: failovers from RRDP to RSYNC.
619: <li>Improved detection of RRDP session desynchronization: a check was

625: RPKI CAs will never issue certificates with V2 unique identifiers.
626: <li>A check to disallow duplicate X.509 certificate extensions was

632: <li>Warnings about unrecoverable message digest mismatches now include
633: the manifestNumber to aid debugging the cause.
634: <li>A check was added to disallow multiple RRDP publish elements for the
635: same file in RRDP snapshots. If this error condition is encountered,
636: the RRDP transfer is failed and the RP falls back to rsync.
637: <li>A compliance check for the proper X.509 Certificate version and CRL
638: version was added.
639: <li>A compliance check was added to ensure CMS Signed Objects contain
640: SignedData, in accordance to RFC 6488 section 3 checklist item 1a.
641: <li>Compliance checks were added for the version, KeyUsage, and
642: ExtendedKeyUsage of EE certificates in Manifest, TAK, and GBR Signed

1.1 deraadt 718: <ul>
1.7 tb 719: <li>Security fixes
720: <ul>
721: <li>Disabled TLSv1.0 and TLSv1.1 in libssl so that they may no longer
722: be selected for use.
723: <li>BN_is_prime{,_fasttest}_ex() refuse to check numbers larger than
724: 32 kbits for primality. This mitigates various DoS vectors.
725: <li>Restricted the RFC 3779 code to IPv4 and IPv6. It was not written
726: to be able to deal with anything else.
727: </ul>
728: <li>Portable changes
729: <ul>
730: <li>Extended the endian.h compat header with hto* and *toh macros.
731: <li>Adapted more tests to the portable framework.
732: <li>Internal tools are now statically linked.
733: <li>Applications bundled as part of the LibreSSL package internally,
734: nc(1) and openssl(1), now are linked statically if static libraries
735: are built.
736: <li>Internal compatibility function symbols are no longer exported from
737: libcrypto. Instead, the libcompat library is linked to libcrypto,
738: libssl, and libtls separately. This increases size a little, but
739: ensures that the libraries are not exporting symbols to programs
740: unintentionally.
741: <li>Selective removal of CET implementation on platforms where it is
742: not supported (macOS).
743: <li>Integrated four more tests.
744: <li>Added Windows ARM64 architecture to tested platforms.
745: <li>Removed Solaris 10 support, fixed Solaris 11.
746: <li>libtls no longer links statically to libcrypto / libssl unless
747: <code>--enable-libtls-only</code> is specified at configure time.
748: <li>Improved Windows compatibility library, namely handling of files vs
749: sockets, correcting an exception when operating on a closed socket.
750: <li>CMake builds no longer hardcode <code>-O2</code> into the compiler flags,
751: instead using flags from the CMake build type instead.
752: <li>Set the CMake default build type to <code>Release</code>. This can be overridden
753: during configuration.
754: <li>Fixed broken ASM support with MinGW builds.
755: </ul>
1.1 deraadt 756: <li>New features
757: <ul>
1.7 tb 758: <li>Added support for truncated SHA-2 and for SHA-3.
759: <li>The BPSW primality test performs additional Miller-Rabin rounds
760: with random bases to reduce the likelihood of composites passing.
761: <li>Allow testing of ciphers and digests using badly aligned buffers
762: in openssl speed using -unalign.
763: <li>Ed25519 certificates are now supported in openssl(1) ca and req.
764: Prepared Ed25519 support in libssl.

766: assembly.
1.1 deraadt 767: </ul>
768: <li>Compatibility changes
769: <ul>
1.7 tb 770: <li>Added a workaround for a poorly thought-out change in OpenSSL 3 that
771: broke privilege separation support in libtls.
772: <li>Moved libtls from ECDSA_METHOD to EC_KEY_METHOD.
773: <li>Removed GF2m support: BIGNUM no longer supports binary extension
774: field arithmetic and all binary elliptic builtin curves were removed.
775: <li>Removed dangerous, "fast" NIST prime and elliptic curve implementations.
776: In particular, EC_GFp_nist_method() is no longer available.
777: <li>Removed most public symbols that were deprecated in OpenSSL 0.9.8.
778: <li>Removed the public X9.31 API (RSA_X931_PADDING is still available).
779: <li>Removed Cipher Text Stealing mode.
780: <li>Removed ENGINE support, including ECDH_METHOD and ECDSA_METHOD.
781: <li>Removed COMP, DSO, dynamic loading of conf modules and support for
782: custom ex_data and error stacks.
783: <li>Removed proxy certificate (RFC 3820) support.
784: <li>Removed SXNET and NETSCAPE_CERT_SEQUENCE support including the
1.8 tb 785: openssl(1) nseq command.
1.7 tb 786: <li>ENGINE support was removed and OPENSSL_NO_ENGINE is set. In spite
787: of this, some stub functions are provided to avoid patching some
788: applications that do not honor OPENSSL_NO_ENGINE.
789: <li>The POLICY_TREE and its related structures and API were removed.
790: <li>In X509_VERIFY_PARAM_inherit() copy hostflags independently of the
791: host list.
792: <li>Made CRYPTO_get_ex_new_index() not return 0 to allow applications
793: to use *_{get,set}_app_data() and *_{get,set}_ex_data() alongside
794: each other.
795: <li>X509_NAME_get_text_by_{NID,OBJ}() now only succeed if they contain
796: valid UTF-8 without embedded NUL.
797: <li>The explicitText user notice uses UTF8String instead of VisibleString
798: to reduce the risk of emitting certificates with invalid DER-encoding.
799: <li>Initial fixes for RSA-PSS support to make the TLSv1.3 stack more
800: compliant with RFC 8446.
801: <li>Fixed EVP_CIPHER_CTX_iv_length() to return what was set with
802: EVP_CTRL_AEAD_SET_IVLEN or one of its aliases.
1.1 deraadt 803: </ul>
1.7 tb 804: <li>Internal improvements
1.1 deraadt 805: <ul>
1.7 tb 806: <li>Improved sieve of Eratosthenes script used for generating a table
807: of small primes.
808: <li>Removed incomplete and dangerous BN_RECURSION code.
809: <li>Imported RFC 5280 policy checking code from BoringSSL and used it
810: to replace the old exponential time code.
811: <li>Converted more of libcrypto to use CBB/CBS.
812: <li>Started cleaning up and rewriting SHA internals.
813: <li>Reduced the dependency of hash implementations on many layers of
814: macros. This results in significant speedups since modern compilers
815: are now less confused.

817: <li>Significantly simplified the BN_BLINDING internals used in RSA.
818: <li>Made BN_num_bits() independent of bn->top.

833: <li>Fix OPENSSL_cpuid_setup() invocations on arm/aarch64.
834: <li>Improved checks for commonName in libtls.

856: <li>Made EVP_PKEY_set1_hkdf_key() fail on a NULL key.
857: <li>On socket errors in the poll loop, netcat could issue system calls
858: on invalidated file descriptors.
859: <li>Allow IP addresses to be specified in a URI.
860: <li>Fixed a copy-paste error in ASN1_TIME_compare() that could lead
861: to two UTCTimes or two GeneralizedTimes incorrectly being compared
862: as equal.
863: </ul>
864: <li>Documentation improvements
865: <ul>
866: <li>Improved documentation of BIO_ctrl(3), BIO_set_info_callback(3),

873: </ul>
874: <li>Testing and Proactive Security
875: <ul>

1.1 deraadt 885: <ul>
1.12 dtucker 886: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
887: generate Ed25519 keys by default. Ed25519 public keys
888: are very convenient due to their small size. Ed25519 keys are
889: specified in RFC 8709 and OpenSSH has supported them since version 6.5
890: (January 2014).
891: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
892: the Subsystem directive now accurately preserves quoting of
893: subsystem commands and arguments. This may change behaviour for exotic
894: configurations, but the most common subsystem configuration
895: (sftp-server) is unlikely to be affected.

1.1 deraadt 902: <ul>
1.12 dtucker 903: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
904: add keystroke timing obfuscation to the client. This attempts
905: to hide inter-keystroke timings by sending interactive traffic at
906: fixed intervals (default: every 20ms) when there is only a small
907: amount of data being sent. It also sends fake "chaff" keystrokes for
908: a random interval after the last real keystroke. These are
909: controlled by a new ssh_config ObscureKeystrokeTiming keyword.
910: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
911: <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
912: Introduce a transport-level ping facility. This adds
913: a pair of SSH transport protocol messages SSH2_MSG_PING/PONG to
914: implement a ping capability. These messages use numbers in the "local
915: extensions" number space and are advertised using a "ping@openssh.com"
916: ext-info message with a string version number of "0".
1.13 dtucker 917: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
918: allow override of Subsystem directives in sshd Match blocks.
919: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
920: allow forwarding Unix Domain sockets via ssh -W.
921: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
922: add support for configuration tags to ssh(1).
923: This adds a ssh_config(5) "Tag" directive and corresponding
924: "Match tag" predicate that may be used to select blocks of
925: configuration similar to the pf.conf(5) keywords of the same
926: name.
927: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
928: add a "match localnetwork" predicate. This allows matching
929: on the addresses of available network interfaces and may be used to
930: vary the effective client configuration based on network location.

934: infrastructure support for KRL
935: extensions. This defines wire formats for optional KRL extensions
936: and implements parsing of the new submessages. No actual extensions
937: are supported at this point.
938: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
939: AuthorizedPrincipalsCommand and AuthorizedKeysCommand now
940: accept two additional %-expansion sequences: %D which expands to
941: the routing domain of the connected session and %C which expands
942: to the addresses and port numbers for the source and destination
943: of the connection.
944: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:

952: fix scp in SFTP mode recursive upload and download of
953: directories that contain symlinks to other directories. In scp mode,
954: the links would be followed, but in SFTP mode they were not.
955: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
956: handle cr+lf (instead of just cr) line endings in
957: sshsig signature files.
958: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
959: interactive mode for ControlPersist sessions if they
960: originally requested a tty.
961: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
962: make PerSourceMaxStartups first-match-wins
963: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
964: limit artificial login delay to a reasonable maximum (5s)
965: and don't delay at all for the "none" authentication mechanism.
1.13 dtucker 966: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
967: Log errors in kex_exchange_identification() with level
1.12 dtucker 968: verbose instead of error to reduce preauth log spam. All of those
969: get logged with a more generic error message by sshpkt_fatal().
970: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
971: correct math for ClientAliveInterval that caused the probes
972: to be sent less frequently than configured.
1.13 dtucker 973: <li><a href="https://man.openbsd.org/ssh-agent.1">ssh-agent(1)</a>:

976: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
977: make -f (fork after authentication) work correctly with

979: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
980: make ConnectTimeout apply to multiplexing sockets and not

986: contains the required symbol before loading it.
987: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
988: fix AuthorizedPrincipalsCommand when AuthorizedKeysCommand
989: appears before it in sshd_config. Since OpenSSH 8.7 the

1.16 jsg 995: remove vestigial support for KRL
1.13 dtucker 996: signatures When the KRL format was originally defined, it included
997: support for signing of KRL objects. However, the code to sign KRLs
1.16 jsg 998: and verify KRL signatures was never completed in OpenSSH. This
1.13 dtucker 999: release removes the partially-implemented code to verify KRLs.
1000: All OpenSSH tools now ignore KRL_SECTION_SIGNATURE sections in
1001: KRL files.
1002: <li>All: fix a number of memory leaks and unreachable/harmless integer
1003: overflows.

1008: <a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1009: better validate CASignatureAlgorithms in
1010: ssh_config and sshd_config. Previously this directive would accept
1011: certificate algorithm names, but these were unusable in practice as
1012: OpenSSH does not support CA chains.
1013: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
1014: make <code>ssh -Q CASignatureAlgorithms</code> only list signature
1015: algorithms that are valid for CA signing. Previous behaviour was
1016: to list all signing algorithms, including certificate algorithms.
1017: <li><a href="https://man.openbsd.org/ssh-keyscan.1">ssh-keyscan(1)</a>:
1018: gracefully handle systems where rlimits or the

1330: <p>
1331: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1332: This file contains everything you need except for the kernel sources,
1333: which are in a separate archive.
1334: To extract:
1335: <blockquote><pre>
1336: # <kbd>mkdir -p /usr/src</kbd>
1337: # <kbd>cd /usr/src</kbd>
1338: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1339: </pre></blockquote>
1340: <p>
1341: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1342: This file contains all the kernel sources you need to rebuild kernels.
1343: To extract:
1344: <blockquote><pre>
1345: # <kbd>mkdir -p /usr/src/sys</kbd>
1346: # <kbd>cd /usr/src</kbd>
1347: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1348: </pre></blockquote>
1349: <p>
1350: Both of these trees are a regular CVS checkout. Using these trees it
1351: is possible to get a head-start on using the anoncvs servers as
1352: described <a href="anoncvs.html">here</a>.
1353: Using these files
1354: results in a much faster initial CVS update than you could expect from
1355: a fresh checkout of the full OpenBSD source tree.

1365: # <kbd>cd /usr</kbd>
1366: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1367: </pre></blockquote>
1368: <p>
1369: Go read the <a href="faq/ports/index.html">ports</a> page
1370: if you know nothing about ports
1371: at this point. This text is not a manual of how to use ports.
1372: Rather, it is a set of notes meant to kickstart the user on the
1373: OpenBSD ports system.
1374: <p>
1375: The <i>ports/</i> directory represents a CVS checkout of our ports.
1376: As with our complete source tree, our ports tree is available via
1377: <a href="anoncvs.html">AnonCVS</a>.
1378: So, in order to keep up to date with the -stable branch, you must make
1379: the <i>ports/</i> tree available on a read-write medium and update the tree
1380: with a command like:
1381: <blockquote><pre>
1382: # <kbd>cd /usr/ports</kbd>
1.2 jsg 1383: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_4</kbd>
1.1 deraadt 1384: </pre></blockquote>
1385: <p>
1386: [Of course, you must replace the server name here with a nearby anoncvs
1387: server.]
1388: <p>
1389: Note that most ports are available as packages on our mirrors. Updated
1390: ports for the 7.4 release will be made available if problems arise.
1391: <p>
1392: If you're interested in seeing a port added, would like to help out, or just
1393: would like to know more, the mailing list
1394: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
