298: of flowspec rules is possible.
299: <li>Update ASPA support to follow draft-ietf-sidrops-aspa-verification-16
300: and draft-ietf-sidrops-aspa-profile-16 by making the ASPA lookup
301: tables AFI-agnostic.
302: <li>Rework UPDATE message generation to use the new ibuf API instead

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

412: <ul>
413: <li>Disabled TLSv1.0 and TLSv1.1 in libssl so that they may no longer
414: be selected for use.
415: <li>BN_is_prime{,_fasttest}_ex() refuse to check numbers larger than
416: 32 kbits for primality. This mitigates various DoS vectors.
417: <li>Restricted the RFC 3779 code to IPv4 and IPv6. It was not written

428: <li>Internal compatibility function symbols are no longer exported from
429: libcrypto. Instead, the libcompat library is linked to libcrypto,
430: libssl, and libtls separately. This increases size a little, but
431: ensures that the libraries are not exporting symbols to programs
432: unintentionally.
433: <li>Selective removal of CET implementation on platforms where it is
434: not supported (macOS).
435: <li>Integrated four more tests.
436: <li>Added Windows ARM64 architecture to tested platforms.

442: <li>CMake builds no longer hardcode <code>-O2</code> into the compiler flags,
443: instead using flags from the CMake build type instead.

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

502: to replace the old exponential time code.
503: <li>Converted more of libcrypto to use CBB/CBS.
504: <li>Started cleaning up and rewriting SHA internals.
505: <li>Reduced the dependency of hash implementations on many layers of

596: add keystroke timing obfuscation to the client. This attempts
597: to hide inter-keystroke timings by sending interactive traffic at
598: fixed intervals (default: every 20ms) when there is only a small
599: amount of data being sent. It also sends fake "chaff" keystrokes for

1020: <h3>Notes about the source code</h3>
1021: <p>
1022: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1023: This file contains everything you need except for the kernel sources,
1024: which are in a separate archive.
1025: To extract:
1026: <blockquote><pre>
1027: # <kbd>mkdir -p /usr/src</kbd>
1028: # <kbd>cd /usr/src</kbd>
1029: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1030: </pre></blockquote>
1031: <p>
1032: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1033: This file contains all the kernel sources you need to rebuild kernels.
1034: To extract:
1035: <blockquote><pre>
1036: # <kbd>mkdir -p /usr/src/sys</kbd>
1037: # <kbd>cd /usr/src</kbd>
1038: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1039: </pre></blockquote>
1040: <p>
1041: Both of these trees are a regular CVS checkout. Using these trees it
1042: is possible to get a head-start on using the anoncvs servers as
1043: described <a href="anoncvs.html">here</a>.
1044: Using these files
1045: results in a much faster initial CVS update than you could expect from
1046: a fresh checkout of the full OpenBSD source tree.

1056: # <kbd>cd /usr</kbd>
1057: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1058: </pre></blockquote>
1059: <p>
1060: Go read the <a href="faq/ports/index.html">ports</a> page
1061: if you know nothing about ports
1062: at this point. This text is not a manual of how to use ports.
1063: Rather, it is a set of notes meant to kickstart the user on the
1064: OpenBSD ports system.
1065: <p>
1066: The <i>ports/</i> directory represents a CVS checkout of our ports.
1067: As with our complete source tree, our ports tree is available via
1068: <a href="anoncvs.html">AnonCVS</a>.
1069: So, in order to keep up to date with the -stable branch, you must make
1070: the <i>ports/</i> tree available on a read-write medium and update the tree
1071: with a command like:
1072: <blockquote><pre>
1073: # <kbd>cd /usr/ports</kbd>
1.2 jsg 1074: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_4</kbd>
1.1 deraadt 1075: </pre></blockquote>
1076: <p>
1077: [Of course, you must replace the server name here with a nearby anoncvs
1078: server.]
1079: <p>
1080: Note that most ports are available as packages on our mirrors. Updated
1081: ports for the 7.4 release will be made available if problems arise.
1082: <p>
1083: If you're interested in seeing a port added, would like to help out, or just
1084: would like to know more, the mailing list
1085: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
