1.11 benno 307:
1.1 deraadt 308: </ul>
309: <li>In <a href="https://man.openbsd.org/bgpd.8">bgpd(8)</a>,
310: <ul>
1.22 claudio 311: <li>Add first version of flowspec support. Right now only announcement
312: of flowspec rules is possible.
313: <li>Update ASPA support to follow draft-ietf-sidrops-aspa-verification-16

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363: withdrawn, and published again.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

429: <li>BN_is_prime{,_fasttest}_ex() refuse to check numbers larger than
430: 32 kbits for primality. This mitigates various DoS vectors.

442: <li>Internal compatibility function symbols are no longer exported from
443: libcrypto. Instead, the libcompat library is linked to libcrypto,
444: libssl, and libtls separately. This increases size a little, but

496: <li>In X509_VERIFY_PARAM_inherit() copy hostflags independently of the
497: host list.
498: <li>Made CRYPTO_get_ex_new_index() not return 0 to allow applications
499: to use *_{get,set}_app_data() and *_{get,set}_ex_data() alongside
500: each other.
501: <li>X509_NAME_get_text_by_{NID,OBJ}() now only succeed if they contain
502: valid UTF-8 without embedded NUL.
503: <li>The explicitText user notice uses UTF8String instead of VisibleString

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

1035: <p>
1036: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1037: This file contains everything you need except for the kernel sources,
1038: which are in a separate archive.
1039: To extract:
1040: <blockquote><pre>
1041: # <kbd>mkdir -p /usr/src</kbd>
1042: # <kbd>cd /usr/src</kbd>
1043: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1044: </pre></blockquote>
1045: <p>
1046: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1047: This file contains all the kernel sources you need to rebuild kernels.
1048: To extract:
1049: <blockquote><pre>
1050: # <kbd>mkdir -p /usr/src/sys</kbd>
1051: # <kbd>cd /usr/src</kbd>
1052: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1053: </pre></blockquote>
1054: <p>
1055: Both of these trees are a regular CVS checkout. Using these trees it
1056: is possible to get a head-start on using the anoncvs servers as
1057: described <a href="anoncvs.html">here</a>.
1058: Using these files
1059: results in a much faster initial CVS update than you could expect from
1060: a fresh checkout of the full OpenBSD source tree.

1071: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>

1073: <p>
1074: Go read the <a href="faq/ports/index.html">ports</a> page
1075: if you know nothing about ports
1076: at this point. This text is not a manual of how to use ports.
1077: Rather, it is a set of notes meant to kickstart the user on the
1078: OpenBSD ports system.
1079: <p>
1080: The <i>ports/</i> directory represents a CVS checkout of our ports.
1081: As with our complete source tree, our ports tree is available via
1082: <a href="anoncvs.html">AnonCVS</a>.
1083: So, in order to keep up to date with the -stable branch, you must make
1084: the <i>ports/</i> tree available on a read-write medium and update the tree
1085: with a command like:
1086: <blockquote><pre>
1087: # <kbd>cd /usr/ports</kbd>
1.2 jsg 1088: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_7_4</kbd>
1.1 deraadt 1089: </pre></blockquote>
1090: <p>
1091: [Of course, you must replace the server name here with a nearby anoncvs
1092: server.]
1093: <p>
1094: Note that most ports are available as packages on our mirrors. Updated
1095: ports for the 7.4 release will be made available if problems arise.
1096: <p>
1097: If you're interested in seeing a port added, would like to help out, or just
1098: would like to know more, the mailing list
1099: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
