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350: withdrawn, and published again.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

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

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

464: broke privilege separation support in libtls.
465: <li>Moved libtls from ECDSA_METHOD to EC_KEY_METHOD.
466: <li>Removed GF2m support: BIGNUM no longer supports binary extension
467: field arithmetic and all binary elliptic builtin curves were removed.
468: <li>Removed dangerous, "fast" NIST prime and elliptic curve implementations.
469: In particular, EC_GFp_nist_method() is no longer available.
470: <li>Removed most public symbols that were deprecated in OpenSSL 0.9.8.
471: <li>Removed the public X9.31 API (RSA_X931_PADDING is still available).

474: <li>Removed COMP, DSO, dynamic loading of conf modules and support for
475: custom ex_data and error stacks.
476: <li>Removed proxy certificate (RFC 3820) support.
477: <li>Removed SXNET and NETSCAPE_CERT_SEQUENCE support including the
1.8 tb 478: openssl(1) nseq command.
1.7 tb 479: <li>ENGINE support was removed and OPENSSL_NO_ENGINE is set. In spite
480: of this, some stub functions are provided to avoid patching some
481: applications that do not honor OPENSSL_NO_ENGINE.
482: <li>The POLICY_TREE and its related structures and API were removed.
483: <li>In X509_VERIFY_PARAM_inherit() copy hostflags independently of the
484: host list.
485: <li>Made CRYPTO_get_ex_new_index() not return 0 to allow applications
486: to use *_{get,set}_app_data() and *_{get,set}_ex_data() alongside
487: each other.
488: <li>X509_NAME_get_text_by_{NID,OBJ}() now only succeed if they contain
489: valid UTF-8 without embedded NUL.
490: <li>The explicitText user notice uses UTF8String instead of VisibleString
491: to reduce the risk of emitting certificates with invalid DER-encoding.
492: <li>Initial fixes for RSA-PSS support to make the TLSv1.3 stack more
493: compliant with RFC 8446.
494: <li>Fixed EVP_CIPHER_CTX_iv_length() to return what was set with

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

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

1.12 dtucker 579: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:
580: generate Ed25519 keys by default. Ed25519 public keys
581: are very convenient due to their small size. Ed25519 keys are

584: <li><a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
585: the Subsystem directive now accurately preserves quoting of

1.12 dtucker 596: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:
597: add keystroke timing obfuscation to the client. This attempts
598: to hide inter-keystroke timings by sending interactive traffic at
599: fixed intervals (default: every 20ms) when there is only a small
600: amount of data being sent. It also sends fake "chaff" keystrokes for

603: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>,
604: <a href="https://man.openbsd.org/sshd.8">sshd(8)</a>:
605: Introduce a transport-level ping facility. This adds
606: a pair of SSH transport protocol messages SSH2_MSG_PING/PONG to
607: implement a ping capability. These messages use numbers in the "local
608: extensions" number space and are advertised using a "ping@openssh.com"

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

619: name.
620: <li><a href="https://man.openbsd.org/ssh.1">ssh(1)</a>:

636: of the connection.
637: <li><a href="https://man.openbsd.org/ssh-keygen.1">ssh-keygen(1)</a>:

1022: <p>
1023: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1024: This file contains everything you need except for the kernel sources,
1025: which are in a separate archive.
1026: To extract:
1027: <blockquote><pre>
1028: # <kbd>mkdir -p /usr/src</kbd>
1029: # <kbd>cd /usr/src</kbd>
1030: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1031: </pre></blockquote>
1032: <p>
1033: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1034: This file contains all the kernel sources you need to rebuild kernels.
1035: To extract:
1036: <blockquote><pre>
1037: # <kbd>mkdir -p /usr/src/sys</kbd>
1038: # <kbd>cd /usr/src</kbd>
1039: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1040: </pre></blockquote>
1041: <p>
1042: Both of these trees are a regular CVS checkout. Using these trees it
1043: is possible to get a head-start on using the anoncvs servers as
1044: described <a href="anoncvs.html">here</a>.
1045: Using these files
1046: results in a much faster initial CVS update than you could expect from
1047: a fresh checkout of the full OpenBSD source tree.

1058: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>

1060: <p>
1061: Go read the <a href="faq/ports/index.html">ports</a> page
1062: if you know nothing about ports
1063: at this point. This text is not a manual of how to use ports.
1064: Rather, it is a set of notes meant to kickstart the user on the
1065: OpenBSD ports system.
1066: <p>
1067: The <i>ports/</i> directory represents a CVS checkout of our ports.
1068: As with our complete source tree, our ports tree is available via
1069: <a href="anoncvs.html">AnonCVS</a>.
1070: So, in order to keep up to date with the -stable branch, you must make
1071: the <i>ports/</i> tree available on a read-write medium and update the tree
1072: with a command like:
1073: <blockquote><pre>
1074: # <kbd>cd /usr/ports</kbd>
1.2 jsg 1075: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_4</kbd>
1.1 deraadt 1076: </pre></blockquote>
1077: <p>
1078: [Of course, you must replace the server name here with a nearby anoncvs
1079: server.]
1080: <p>
1081: Note that most ports are available as packages on our mirrors. Updated
1082: ports for the 7.4 release will be made available if problems arise.
1083: <p>
1084: If you're interested in seeing a port added, would like to help out, or just
1085: would like to know more, the mailing list
1086: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
