351: too many updates end up queued in the TCP stack.
352: <li>Adjusted example <code>GRACEFUL_SHUTDOWN</code> filter rule in
353: the example config to only match on ebgp sessions.

356: <ul>
1.23 claudio 357: <li>A 30%-50% performance improvement was achieved through libcrypto's
358: partial chains certificate validation feature. Already validated
359: non-inheriting CA certificates are now marked as trusted roots. This
360: way it can be ensured that a leaf's delegated resources are properly
361: covered, and at the same time most validation paths are
362: significantly shortened.
363: <li>Support for gzip and deflate HTTP Content-Encoding compression was
364: added. This allows web servers to send RRDP XML in compressed form,
365: saving around 50% of bandwidth.
366: <li>ASPA support was updated to draft-ietf-sidrops-aspa-profile-16.
367: As part of supporting AFI-agnostic ASPAs, the JSON syntax for
368: Validated ASPA Payloads changed in both filemode and normal output.
369: <li>In filemode (-f option) the applicable manifests are now shown as
370: part of the signature path.
371: <li>A new -P option was added to manually specify a moment in time
372: to use when parsing the validity window of certificates. Useful
373: for regression testing. Default is invocation time of rpki-client.
374: <li>The -A option will now also exclude ASPA data from the JSON output.
375: <li>The synchronisation protocol used to sync the repository is now
376: included in the OpenMetrics output.
377: <li>Improved accounting by tracking objects both by repo and tal.
378: <li>Check whether products listed on a manifest were issued by the same
379: authority as the manifest itself.
380: <li>File modification timestamps of objects retrieved via RRDP are now
381: deterministically set to prepare the on-disk cache for seamless
382: failovers from RRDP to RSYNC.
383: <li>Improved detection of RRDP session desynchronization: a check was
384: added to compare whether the delta hashes associated to previously
385: seen serials are different in newly fetched notification files.
386: <li>Improved handling of RRDP deltas in which objects are published,
387: withdrawn, and published again.
388: <li>Disallow X.509 v2 issuer and subject unique identifiers in certs.
389: RPKI CAs will never issue certificates with V2 unique identifiers.
390: <li>A check to disallow duplicate X.509 certificate extensions was
391: added.
392: <li>A check to disallow empty sets of IP Addresses or AS numbers in RFC
393: 3779 extensions was added.

395: Object is missing.
396: <li>Warnings about unrecoverable message digest mismatches now include
397: the manifestNumber to aid debugging the cause.
398: <li>A check was added to disallow multiple RRDP publish elements for the
399: same file in RRDP snapshots. If this error condition is encountered,
400: the RRDP transfer is failed and the RP falls back to rsync.
401: <li>A compliance check for the proper X.509 Certificate version and CRL
402: version was added.
403: <li>A compliance check was added to ensure CMS Signed Objects contain
404: SignedData, in accordance to RFC 6488 section 3 checklist item 1a.
405: <li>Compliance checks were added for the version, KeyUsage, and
406: ExtendedKeyUsage of EE certificates in Manifest, TAK, and GBR Signed
407: Objects.
408: <li>A CMS signing-time value being after the X.509 notAfter timestamp
409: was downgraded from an error to a warning.
410: <li>A bug was fixed in the handling of CA certificates which inherit IP
411: resources.
412: <li>A compliance check was added to ensure the X.509 Subject only
413: contains commonName and optionally serialNumber.
414: <li>A compliance check was added to ensure the CMS SignedData and
415: SignerInfo versions to be 3.
416: <li>Fisher-Yates shuffle the order in which Manifest entries are
417: processed. Previously, work items were enqueued in the order the CA
418: intended them to appear on a Manifest. However, there is no obvious
419: benefit to third parties deciding the order in which things are

1061: This file contains everything you need except for the kernel sources,
1062: which are in a separate archive.
1063: To extract:
1064: <blockquote><pre>
1065: # <kbd>mkdir -p /usr/src</kbd>
1066: # <kbd>cd /usr/src</kbd>
1067: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1068: </pre></blockquote>
1069: <p>
1070: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1071: This file contains all the kernel sources you need to rebuild kernels.
1072: To extract:
1073: <blockquote><pre>
1074: # <kbd>mkdir -p /usr/src/sys</kbd>
1075: # <kbd>cd /usr/src</kbd>
1076: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>

1079: Both of these trees are a regular CVS checkout. Using these trees it
1080: is possible to get a head-start on using the anoncvs servers as
1081: described <a href="anoncvs.html">here</a>.
1082: Using these files

1101: Rather, it is a set of notes meant to kickstart the user on the
1102: OpenBSD ports system.
1103: <p>
1104: The <i>ports/</i> directory represents a CVS checkout of our ports.
1105: As with our complete source tree, our ports tree is available via
1106: <a href="anoncvs.html">AnonCVS</a>.
1107: So, in order to keep up to date with the -stable branch, you must make
1108: the <i>ports/</i> tree available on a read-write medium and update the tree
1109: with a command like:
1110: <blockquote><pre>
1111: # <kbd>cd /usr/ports</kbd>

1.1 deraadt 1113: </pre></blockquote>
1114: <p>
1115: [Of course, you must replace the server name here with a nearby anoncvs
1116: server.]
1117: <p>
1118: Note that most ports are available as packages on our mirrors. Updated
1119: ports for the 7.4 release will be made available if problems arise.
1120: <p>
1121: If you're interested in seeing a port added, would like to help out, or just
1122: would like to know more, the mailing list
1123: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
