313: the example config to only match on ebgp sessions.
1.1 deraadt 314: </ul>
315: <li><a href="https://man.openbsd.org/rpki-client.8">rpki-client(8)</a> saw some changes:
316: <ul>
1.23 ! claudio 317: <li>A 30%-50% performance improvement was achieved through libcrypto's
! 318: partial chains certificate validation feature. Already validated
! 319: non-inheriting CA certificates are now marked as trusted roots. This
! 320: way it can be ensured that a leaf's delegated resources are properly
! 321: covered, and at the same time most validation paths are
! 322: significantly shortened.
! 323: <li>Support for gzip and deflate HTTP Content-Encoding compression was
! 324: added. This allows web servers to send RRDP XML in compressed form,
! 325: saving around 50% of bandwidth.
! 326: <li>ASPA support was updated to draft-ietf-sidrops-aspa-profile-16.
! 327: As part of supporting AFI-agnostic ASPAs, the JSON syntax for
! 328: Validated ASPA Payloads changed in both filemode and normal output.
! 329: <li>In filemode (-f option) the applicable manifests are now shown as
! 330: part of the signature path.
! 331: <li>A new -P option was added to manually specify a moment in time
! 332: to use when parsing the validity window of certificates. Useful
! 333: for regression testing. Default is invocation time of rpki-client.
! 334: <li>The -A option will now also exclude ASPA data from the JSON output.
! 335: <li>The synchronisation protocol used to sync the repository is now
! 336: included in the OpenMetrics output.
! 337: <li>Improved accounting by tracking objects both by repo and tal.
! 338: <li>Check whether products listed on a manifest were issued by the same
! 339: authority as the manifest itself.
! 340: <li>File modification timestamps of objects retrieved via RRDP are now
! 341: deterministically set to prepare the on-disk cache for seamless
! 342: failovers from RRDP to RSYNC.
! 343: <li>Improved detection of RRDP session desynchronization: a check was
! 344: added to compare whether the delta hashes associated to previously
! 345: seen serials are different in newly fetched notification files.
! 346: <li>Improved handling of RRDP deltas in which objects are published,
! 347: withdrawn, and published again.
! 348: <li>Disallow X.509 v2 issuer and subject unique identifiers in certs.
! 349: RPKI CAs will never issue certificates with V2 unique identifiers.
! 350: <li>A check to disallow duplicate X.509 certificate extensions was
! 351: added.
! 352: <li>A check to disallow empty sets of IP Addresses or AS numbers in RFC
! 353: 3779 extensions was added.
! 354: <li>A warning is printed when the CMS signing-time attribute in a Signed
! 355: Object is missing.
! 356: <li>Warnings about unrecoverable message digest mismatches now include
! 357: the manifestNumber to aid debugging the cause.
! 358: <li>A check was added to disallow multiple RRDP publish elements for the
! 359: same file in RRDP snapshots. If this error condition is encountered,
! 360: the RRDP transfer is failed and the RP falls back to rsync.
! 361: <li>A compliance check for the proper X.509 Certificate version and CRL
! 362: version was added.
! 363: <li>A compliance check was added to ensure CMS Signed Objects contain
! 364: SignedData, in accordance to RFC 6488 section 3 checklist item 1a.
! 365: <li>Compliance checks were added for the version, KeyUsage, and
! 366: ExtendedKeyUsage of EE certificates in Manifest, TAK, and GBR Signed
! 367: Objects.
! 368: <li>A CMS signing-time value being after the X.509 notAfter timestamp
! 369: was downgraded from an error to a warning.
! 370: <li>A bug was fixed in the handling of CA certificates which inherit IP
! 371: resources.
! 372: <li>A compliance check was added to ensure the X.509 Subject only
! 373: contains commonName and optionally serialNumber.
! 374: <li>A compliance check was added to ensure the CMS SignedData and
! 375: SignerInfo versions to be 3.
! 376: <li>Fisher-Yates shuffle the order in which Manifest entries are
! 377: processed. Previously, work items were enqueued in the order the CA
! 378: intended them to appear on a Manifest. However, there is no obvious
! 379: benefit to third parties deciding the order in which things are
! 380: processed.

1.7 tb 409: <li>Security fixes
410: <ul>
411: <li>Disabled TLSv1.0 and TLSv1.1 in libssl so that they may no longer
412: be selected for use.
413: <li>BN_is_prime{,_fasttest}_ex() refuse to check numbers larger than
414: 32 kbits for primality. This mitigates various DoS vectors.
415: <li>Restricted the RFC 3779 code to IPv4 and IPv6. It was not written
416: to be able to deal with anything else.
417: </ul>
418: <li>Portable changes
419: <ul>
420: <li>Extended the endian.h compat header with hto* and *toh macros.

423: <li>Applications bundled as part of the LibreSSL package internally,
424: nc(1) and openssl(1), now are linked statically if static libraries
425: are built.
426: <li>Internal compatibility function symbols are no longer exported from
427: libcrypto. Instead, the libcompat library is linked to libcrypto,
428: libssl, and libtls separately. This increases size a little, but
429: ensures that the libraries are not exporting symbols to programs
430: unintentionally.
431: <li>Selective removal of CET implementation on platforms where it is
432: not supported (macOS).
433: <li>Integrated four more tests.
434: <li>Added Windows ARM64 architecture to tested platforms.
435: <li>Removed Solaris 10 support, fixed Solaris 11.
436: <li>libtls no longer links statically to libcrypto / libssl unless
437: <code>--enable-libtls-only</code> is specified at configure time.
438: <li>Improved Windows compatibility library, namely handling of files vs
439: sockets, correcting an exception when operating on a closed socket.
440: <li>CMake builds no longer hardcode <code>-O2</code> into the compiler flags,
441: instead using flags from the CMake build type instead.
442: <li>Set the CMake default build type to <code>Release</code>. This can be overridden
443: during configuration.
444: <li>Fixed broken ASM support with MinGW builds.

461: broke privilege separation support in libtls.
462: <li>Moved libtls from ECDSA_METHOD to EC_KEY_METHOD.
463: <li>Removed GF2m support: BIGNUM no longer supports binary extension
464: field arithmetic and all binary elliptic builtin curves were removed.
465: <li>Removed dangerous, "fast" NIST prime and elliptic curve implementations.
466: In particular, EC_GFp_nist_method() is no longer available.
467: <li>Removed most public symbols that were deprecated in OpenSSL 0.9.8.
468: <li>Removed the public X9.31 API (RSA_X931_PADDING is still available).
469: <li>Removed Cipher Text Stealing mode.
470: <li>Removed ENGINE support, including ECDH_METHOD and ECDSA_METHOD.
471: <li>Removed COMP, DSO, dynamic loading of conf modules and support for
472: custom ex_data and error stacks.
473: <li>Removed proxy certificate (RFC 3820) support.
474: <li>Removed SXNET and NETSCAPE_CERT_SEQUENCE support including the
1.8 tb 475: openssl(1) nseq command.
1.7 tb 476: <li>ENGINE support was removed and OPENSSL_NO_ENGINE is set. In spite
477: of this, some stub functions are provided to avoid patching some
478: applications that do not honor OPENSSL_NO_ENGINE.
479: <li>The POLICY_TREE and its related structures and API were removed.
480: <li>In X509_VERIFY_PARAM_inherit() copy hostflags independently of the
481: host list.
482: <li>Made CRYPTO_get_ex_new_index() not return 0 to allow applications
483: to use *_{get,set}_app_data() and *_{get,set}_ex_data() alongside
484: each other.
485: <li>X509_NAME_get_text_by_{NID,OBJ}() now only succeed if they contain
486: valid UTF-8 without embedded NUL.
487: <li>The explicitText user notice uses UTF8String instead of VisibleString
488: to reduce the risk of emitting certificates with invalid DER-encoding.
489: <li>Initial fixes for RSA-PSS support to make the TLSv1.3 stack more
490: compliant with RFC 8446.
491: <li>Fixed EVP_CIPHER_CTX_iv_length() to return what was set with

499: <li>Imported RFC 5280 policy checking code from BoringSSL and used it
500: to replace the old exponential time code.
501: <li>Converted more of libcrypto to use CBB/CBS.
502: <li>Started cleaning up and rewriting SHA internals.
503: <li>Reduced the dependency of hash implementations on many layers of
504: macros. This results in significant speedups since modern compilers

548: on invalidated file descriptors.
549: <li>Allow IP addresses to be specified in a URI.
550: <li>Fixed a copy-paste error in ASN1_TIME_compare() that could lead

552: as equal.
553: </ul>
554: <li>Documentation improvements

1.12 dtucker 576: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
577: generate Ed25519 keys by default. Ed25519 public keys
578: are very convenient due to their small size. Ed25519 keys are
579: specified in RFC 8709 and OpenSSH has supported them since version 6.5
580: (January 2014).
581: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
582: the Subsystem directive now accurately preserves quoting of
583: subsystem commands and arguments. This may change behaviour for exotic

1.1 deraadt 592: <ul>
1.12 dtucker 593: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
594: add keystroke timing obfuscation to the client. This attempts
595: to hide inter-keystroke timings by sending interactive traffic at
596: fixed intervals (default: every 20ms) when there is only a small
597: amount of data being sent. It also sends fake "chaff" keystrokes for
598: a random interval after the last real keystroke. These are
599: controlled by a new ssh_config ObscureKeystrokeTiming keyword.
600: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
601: <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
602: Introduce a transport-level ping facility. This adds
603: a pair of SSH transport protocol messages SSH2_MSG_PING/PONG to
604: implement a ping capability. These messages use numbers in the "local
605: extensions" number space and are advertised using a "ping@openssh.com"

610: allow forwarding Unix Domain sockets via ssh -W.
611: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
612: add support for configuration tags to ssh(1).
613: This adds a ssh_config(5) "Tag" directive and corresponding
614: "Match tag" predicate that may be used to select blocks of
615: configuration similar to the pf.conf(5) keywords of the same
616: name.
617: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:

628: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
629: AuthorizedPrincipalsCommand and AuthorizedKeysCommand now

632: to the addresses and port numbers for the source and destination
633: of the connection.
634: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:

645: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:

659: get logged with a more generic error message by sshpkt_fatal().
660: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
661: correct math for ClientAliveInterval that caused the probes

1.16 jsg 685: remove vestigial support for KRL

687: support for signing of KRL objects. However, the code to sign KRLs
1.16 jsg 688: and verify KRL signatures was never completed in OpenSSH. This
1.13 dtucker 689: release removes the partially-implemented code to verify KRLs.
690: All OpenSSH tools now ignore KRL_SECTION_SIGNATURE sections in

702: OpenSSH does not support CA chains.
703: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
704: make <code>ssh -Q CASignatureAlgorithms</code> only list signature

706: to list all signing algorithms, including certificate algorithms.
707: <li><a href="https://man.openbsd.org/ssh-keyscan.1">ssh-keyscan(1)</a>:

1019: <p>
1020: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1021: This file contains everything you need except for the kernel sources,
1022: which are in a separate archive.
1023: To extract:
1024: <blockquote><pre>
1025: # <kbd>mkdir -p /usr/src</kbd>
1026: # <kbd>cd /usr/src</kbd>
1027: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1028: </pre></blockquote>
1029: <p>
1030: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1031: This file contains all the kernel sources you need to rebuild kernels.
1032: To extract:
1033: <blockquote><pre>
1034: # <kbd>mkdir -p /usr/src/sys</kbd>
1035: # <kbd>cd /usr/src</kbd>
1036: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1037: </pre></blockquote>
1038: <p>
1039: Both of these trees are a regular CVS checkout. Using these trees it
1040: is possible to get a head-start on using the anoncvs servers as
1041: described <a href="anoncvs.html">here</a>.
1042: Using these files
1043: results in a much faster initial CVS update than you could expect from
1044: a fresh checkout of the full OpenBSD source tree.

1055: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1056: </pre></blockquote>
1057: <p>
1058: Go read the <a href="faq/ports/index.html">ports</a> page
1059: if you know nothing about ports
1060: at this point. This text is not a manual of how to use ports.
1061: Rather, it is a set of notes meant to kickstart the user on the
1062: OpenBSD ports system.
1063: <p>
1064: The <i>ports/</i> directory represents a CVS checkout of our ports.
1065: As with our complete source tree, our ports tree is available via
1066: <a href="anoncvs.html">AnonCVS</a>.
1067: So, in order to keep up to date with the -stable branch, you must make
1068: the <i>ports/</i> tree available on a read-write medium and update the tree
1069: with a command like:
1070: <blockquote><pre>
1071: # <kbd>cd /usr/ports</kbd>
1.2 jsg 1072: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_4</kbd>
1.1 deraadt 1073: </pre></blockquote>
1074: <p>
1075: [Of course, you must replace the server name here with a nearby anoncvs
1076: server.]
1077: <p>
1078: Note that most ports are available as packages on our mirrors. Updated
1079: ports for the 7.4 release will be made available if problems arise.
1080: <p>
1081: If you're interested in seeing a port added, would like to help out, or just
1082: would like to know more, the mailing list
1083: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
