445: length provided is 0 to match the OpenSSL behaviour. Issue noticed
1.36 tb 446: by Christian Heimes <christian@python.org>
1.29 beck 447: <li> Added support for many OpenSSL 1.0.2 and 1.1 APIs, based on
448: observations of real-world usage in applications. These are
449: implemented in parallel with existing OpenSSL 1.0.1 APIs - visibility
450: changes have not been made to existing structs, allowing code written
451: for older OpenSSL APIs to continue working.
452: <li> Extensive corrections, improvements, and additions to the
453: API documentation, including new public APIs from OpenSSL that had
454: no pre-existing documentation.
455: <li> Added support for automatic library initialization in libcrypto,
456: libssl, and libtls. Support for pthread_once or a compatible
457: equivalent is now required of the target operating system. As a
458: side-effect, minimum Windows support is Vista or higher.
459: <li> Converted more packet handling methods to CBB, which improves
460: resiliency when generating TLS messages.
461: <li> Completed TLS extension handling rewrite, improving consistency of
462: checks for malformed and duplicate extensions.
463: <li>Rewrote ASN1_TYPE_{get,set}_octetstring() using templated ASN.1.
464: This removes the last remaining use of the old M_ASN1_* macros
465: (asn1_mac.h) from API that needs to continue to exist.
466: <li> Added support for client-side session resumption in libtls.
467: A libtls client can specify a session file descriptor (a regular
468: file with appropriate ownership and permissions) and libtls will
469: manage reading and writing of session data across TLS handshakes.
470: <li> Improved support for strict alignment on ARMv7 architectures,
471: conditionally enabling assembly in those cases.
472: <li> Fixed a memory leak in libtls when reusing a tls_config.
473: <li> Merged more DTLS support into the regular TLS code path, removing
474: duplicated code.

803: <tt>src.tar.gz</tt> contains a source archive starting at <tt>/usr/src</tt>.
804: This file contains everything you need except for the kernel sources,
805: which are in a separate archive.
806: To extract:
807:
808: <blockquote><pre>
809: # <b>mkdir -p /usr/src</b>
810: # <b>cd /usr/src</b>
811: # <b>tar xvfz /tmp/src.tar.gz</b>
812: </pre></blockquote>
813:
814: <tt>sys.tar.gz</tt> contains a source archive starting at <tt>/usr/src/sys</tt>.
815: This file contains all the kernel sources you need to rebuild kernels.
816: To extract:
817:
818: <blockquote><pre>
819: # <b>mkdir -p /usr/src/sys</b>
820: # <b>cd /usr/src</b>
821: # <b>tar xvfz /tmp/sys.tar.gz</b>
822: </pre></blockquote>

824: Both of these trees are a regular CVS checkout. Using these trees it
825: is possible to get a head-start on using the anoncvs servers as
826: described <a href="anoncvs.html">here</a>.
827: Using these files
828: results in a much faster initial CVS update than you could expect from
829: a fresh checkout of the full OpenBSD source tree.

839: # <b>cd /usr</b>

843: Go read the <a href="faq/ports/index.html">ports</a> page
844: if you know nothing about ports
845: at this point. This text is not a manual of how to use ports.
846: Rather, it is a set of notes meant to kickstart the user on the
847: OpenBSD ports system.
848: <p>
849: The <i>ports/</i> directory represents a CVS checkout of our ports.
850: As with our complete source tree, our ports tree is available via
851: <a href="anoncvs.html">AnonCVS</a>.
852: So, in order to keep up to date with the -stable branch, you must make
853: the <i>ports/</i> tree available on a read-write medium and update the tree
854: with a command like:
855:
856: <blockquote><pre>
857: # <b>cd /usr/ports</b>
858: # <b>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_6_3</b>
859: </pre></blockquote>
860:
861: [Of course, you must replace the server name here with a nearby anoncvs
862: server.]
863: <p>
864: Note that most ports are available as packages on our mirrors. Updated
865: ports for the 6.3 release will be made available if problems arise.
866: <p>
867: If you're interested in seeing a port added, would like to help out, or just
868: would like to know more, the mailing list
869: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
