77: <ul>
78:
79: <li>General improvements and bugfixes:
80: <ul>
81: <li>Reduced the minimum allowed number of chunks in a CONCAT
82: volume from 2 to 1, increasing the number of volumes which can be
83: created on a single disk with <a
84: href="https://man.openbsd.org/bioctl">bioctl(8)</a> from 7 to 15. This
85: can be used to create more partitions than previously.
86: <li>Rewrote the <a href="https://man.openbsd.org/cron">cron(8)</a>
87: flag-parsing code to be getopt-like, allowing tight formations like
88: -ns and flag repetition. Renamed the "options" field in <a
89: href="https://man.openbsd.org/crontab">crontab(5)</a> to "flags".
90: <li>Added <a
91: href="https://man.openbsd.org/man5/crontab.5">crontab(5)</a> -s flag
92: to the command field, indicating that only a single instance of the
93: job should run concurrently.
94: <li>Added <a href="https://man.openbsd.org/cron">cron(8)</a>
95: support for random values using the ~ operator.

116: <li>Prevented a kernel hang when no unlocked ffs_softdep worklist
117: items could be processed.
118: <li>Stopped counting pages mapped as PROT_NONE against the
119: RLIMIT_DATA limit, helping code which reserves large chunks of address
120: space but populates it sparsely.
121: <li>Added the $REQUEST_SCHEME variable to <a
122: href="https://man.openbsd.org/httpd.conf">httpd.conf(5)</a>, allowing
123: preservation of the original connection type (http or https) for
124: redirect locations
125: <li>Implemented "strip" option in <a
126: href="https://man.openbsd.org/httpd.conf">httpd.conf(5)</a> for
127: fastcgi to be able to have multiple chroots under /var/www for FastCGI
128: servers.
129: <li>Changed <a href="https://man.openbsd.org/httpd">httpd(8)</a>
130: to send a 408 response when a timeout happens while headers are being
131: received, but close the connection if no request is received.
132: <li>Updated en_US.UTF-8.src to Unicode 12.1.
1.19 deraadt 133: <li>Added a new __tmpfd system call which creates a new, unnamed file in
134: /tmp, intended for shm/fd passing, but in programs that may otherwise
135: lack filesystem access (due to restrictions imposed by
136: <a href="https://man.openbsd.org/unveil.2">unveil(2)</a> or
137: <a href="https://man.openbsd.org/pledge.2">pledge(2)</a>).

170: <li>Modified -z mode verification in <a
171: href="https://man.openbsd.org/signify">signify(1)</a> to save the
172: header and output it, so signify -zV >saved.tgz will keep the
173: signature for later checks.
174: <li>Enabled DNSSEC validation in <a
175: href="https://man.openbsd.org/unbound">unbound(8)</a> by default.

560: <li>Implemented a workaround for missing Tx completion interrupts
561: in <a href="https://man.openbsd.org/iwm">iwm(4)</a> which could lead
562: to failures when roaming to another AP.
563: <li>Re-enabled firmware-based Tx retries at lower rates for <a
564: href="https://man.openbsd.org/iwm">iwm(4)</a>, reducing packet loss.
565: <li>Fixed automatic Tx rate control issues in <a

1528: <h3>Notes about the source code</h3>
1529: <p>
1530: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1531: This file contains everything you need except for the kernel sources,
1532: which are in a separate archive.
1533: To extract:
1534: <blockquote><pre>
1535: # <kbd>mkdir -p /usr/src</kbd>
1536: # <kbd>cd /usr/src</kbd>
1537: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1538: </pre></blockquote>
1539: <p>
1540: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1541: This file contains all the kernel sources you need to rebuild kernels.
1542: To extract:
1543: <blockquote><pre>
1544: # <kbd>mkdir -p /usr/src/sys</kbd>
1545: # <kbd>cd /usr/src</kbd>
1546: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1547: </pre></blockquote>
1548: <p>
1549: Both of these trees are a regular CVS checkout. Using these trees it
1550: is possible to get a head-start on using the anoncvs servers as
1551: described <a href="anoncvs.html">here</a>.
1552: Using these files
1553: results in a much faster initial CVS update than you could expect from
1554: a fresh checkout of the full OpenBSD source tree.

1562: A ports tree archive is also provided. To extract:
1563: <blockquote><pre>
1564: # <kbd>cd /usr</kbd>
1565: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1566: </pre></blockquote>
1567: <p>
1568: Go read the <a href="faq/ports/index.html">ports</a> page
1569: if you know nothing about ports
1570: at this point. This text is not a manual of how to use ports.
1571: Rather, it is a set of notes meant to kickstart the user on the
1572: OpenBSD ports system.
1573: <p>
1574: The <i>ports/</i> directory represents a CVS checkout of our ports.
1575: As with our complete source tree, our ports tree is available via
1576: <a href="anoncvs.html">AnonCVS</a>.
1577: So, in order to keep up to date with the -stable branch, you must make
1578: the <i>ports/</i> tree available on a read-write medium and update the tree
1579: with a command like:
1580: <blockquote><pre>
1581: # <kbd>cd /usr/ports</kbd>
1582: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_6_7</kbd>
1583: </pre></blockquote>
1584: <p>
1585: [Of course, you must replace the server name here with a nearby anoncvs
1586: server.]
1587: <p>
1588: Note that most ports are available as packages on our mirrors. Updated
1589: ports for the 6.7 release will be made available if problems arise.
1590: <p>
1591: If you're interested in seeing a port added, would like to help out, or just
1592: would like to know more, the mailing list
1593: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
