71: <h3>What's New</h3>
72: <p>
73: This is a partial list of new features and systems included in OpenBSD 6.7.
74: For a comprehensive list, see the <a href="plus67.html">changelog</a> leading
75: to 6.7.
76:
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.
96: <li>Allowed <a href="https://man.openbsd.org/cwm">cwm(1)</a>
97: configuration of window size based on percentage of the master window
98: during horizontal and vertical tiling actions.

102: allowing use of <a href="https://man.openbsd.org/witness">
103: witness(4)</a>.
104: <li>Added <a href="https://man.openbsd.org/acpi">acpi(4)</a>
105: support for the _CCA method, indicating whether DMA is cache-coherent.
106: <li>Switched the default compiler on powerpc to clang.
107: <li>Bumped <a href="https://man.openbsd.org/nvme">nvme(4)</a> max
108: physio() i/o size to 128K.
109: <li>Blocked <a href="https://man.openbsd.org/apmd">apmd(8)</a>
110: autoaction for 60 seconds after resume, preventing spurious
111: suspend/resume cycles.
112: <li>Checked battery life against autoaction level on power change
113: events in <a href="https://man.openbsd.org/apmd">apmd(8)</a>, making
114: -z/-Z work with <a
115: href="https://man.openbsd.org/acpibat">acpibat(4)</a>.
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>).

156: avoid backwardly compatible behavior.
157: <li>Added the system clock interface <a
158: href="https://man.openbsd.org/nanoboottime">nanoboottime(9)</a>,
159: returning the UTC time at which the system booted in seconds and

161: <li>Introduced efficient page freeing in reverse order from uvm,
162: greatly improving cases of massive page freeing.
163: <li>Added uvm_objfree to uvm to efficiently free all pages from a
164: uvm object, used in the buffer cache for considerable speedup when
165: freeing pages.

167: speed page lookups.
168: <li>Speed up <a href="https://man.openbsd.org/sort">sort(1)</a> by
169: not performing a top-level sort when -c is used with a -k field.
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.

640: <li>Prevented non-root users from using <a
641: href="https://man.openbsd.org/ioctl">ioctl(2)</a> to alter the address
642: of a network interface.
643: <li>Prevented non-root users from setting the parameters of <a
644: href="https://man.openbsd.org/pppoe">pppoe(4)</a> interfaces.
645: <li>Removed mobileip(4).
646: <li>Stopped checking whether the IPv6 source address of a neighbor

648: with RFC 4861.
649:
650: </ul>
651:
652: <li>Installer improvements:
653: <ul>
654: <li>Simplified <a
655: href="https://man.openbsd.org/sysupgrade">sysupgrade(8)</a> directory
656: check and creation (/home/_syspatch). It can now be a symlink.

665:
666: <li>Security improvements:
667: <ul>
668: <li><a href="https://man.openbsd.org/unveil.2">unveil(2)</a> is
1.6 benno 669: now used in 82 userland programs to redact filesystem access.
1.1 benno 670: <li>Used <a href="https://man.openbsd.org/unveil">unveil(2)</a> to
671: reduce filesystem access in <a
672: href="https://man.openbsd.org/vmstat">vmstat(8)</a>, <a

679: href="https://man.openbsd.org/nslookup">nslookup(1)</a> from the
680: bind(8) source code, cleanup the source code by removing not needed
681: features and auditing it. The kernel API accessible to these
682: programs is now restricted through <a
683: href="https://man.openbsd.org/pledge">pledge(2)</a>.
1.2 deraadt 684: <li>System calls may now only be performed from selected code regions:
685: the main program, <a href="https://man.openbsd.org/ld.so">ld.so(1)</a>,
686: libc.so and the signal trampoline. A new system call
687: <a href="https://man.openbsd.org/msyscall">msyscall(2)</a> indicates
1.5 deraadt 688: the libc range, and activates the locking. This change hardens
1.2 deraadt 689: against some attack methods.
1.1 benno 690: <li>Prevented stack trace saving from inspecting untrusted data on
691: amd64, arm64 and i386.
692: <li>Used lfence in place of stac/clac on pre-SMAP CPUs to protect
693: against Load-Value-Injection attacks against the kernel.
694: <li>Prevented a panic due to missing <a
695: href="https://man.openbsd.org/sysctl">sysctl(2)</a> input validation.
696: <li>Injected failure to fetch entropy with an rdrand() timeout as
697: an entropic event, along with an additional rdtsc measuring the vmexit
698: latency.
699: <li>Enforced that <a href="https://man.openbsd.org/ksh">ksh(1)</a>
700: TMOUT is an integer literal to prevent command execution from the
701: environment at shell initialization time.
702: <li>Ensured the first 2MB page of the amd64 kernel is correctly
703: mapped read-only in the direct map.
704: <li>Addressed an arm64 speculative execution issue by changing the
705: arm64 system call ABI to skip two instructions and inserting a barrier
706: after each system call.
707: <li>Fixed arm64 speculative execution of instructions after ERET,
708: which had led to spectre-like effects on some processors.
709: <li>Tightened permissions for USB device nodes.
710: <li>Ensured that <a
711: href="https://man.openbsd.org/ld.so">ld.so(1)</a> removed the
712: LD_LIBRARY_PATH environment variable for set-user-ID and set-group-ID
713: executables in low memory conditions.
714: <li>Added support for RSA-PSS to <a
715: href="https://man.openbsd.org/crypto">crypto(3)</a>.
716: <li>Added retguard for octeon/mips64.

722: CVE-2019-19519.
723: <li>Fixed insufficient username validation performed by libc's
724: authentication privilege separation layer and added additional
725: validation points, further validating in <a
726: href="https://man.openbsd.org/login">login(1)</a> and <a
727: href="https://man.openbsd.org/su">su(1)</a>.
728: <li>Prevented escalation to the auth group in <a
729: href="https://man.openbsd.org/xlock">xlock(1)</a> through path-related
730: environment variables and disabled mesa and opengl functionality.
731: </ul>
732: </ul>
733:
734: <li>Routing daemons and other userland network improvements:
735: <ul>
736: <!-- bgpd -->
737: <li>Store both IPv4 and IPv6 addresses with local-address in <a
738: href="https://man.openbsd.org/bgpd">bgpd(8)</a>, allowing
739: configuration of both an IPv4 and IPv6 local-address on a group with
740: correct binding of neighbors. Introduced 'no local-address' to reset a
741: previously-set local address back to zero. This helps to reduce
742: repetition in the configuration.
743: <li>Aggregated duplicate <a
744: href="https://man.openbsd.org/bgpd">bgpd(8)</a> roa table
745: prefix/source-as combos as a single entry with the longest maxlen
746: length.
747: <li>Extended <a href="https://man.openbsd.org/bgpctl">bgpctl(8)</a>

751: href="https://man.openbsd.org/bgpd.conf">bgpd.conf(5)</a>
752: <code>max-prefix NUM out</code> to limit the number of announced
753: prefixes, avoiding leaks of full tables to upstreams and peers.
754: <li>Began marking stale prefixes in the Adj-RIB-out during
755: graceful reload of <a href="https://man.openbsd.org/bgpd">bgpd(8)</a>
756: and fixed prefix_withdraw to check the correct prefix flags before
757: removing a prefix from the update or withdraw tree.
758: <li>Fixed a bug with the fatal <a
759: href="https://man.openbsd.org/bgpd">bgpd(8)</a> non-existing prefix
760: call to ensure the missing prefix is inserted into the prefix tree.
761: <li>Fixed <a href="https://man.openbsd.org/bgpd">bgpd(8)</a>
762: crashes where the nexthop_runners tail queue was corrupted.

777: href="https://man.openbsd.org/ripd">ripd(8)</a> when entries are
778: skipped due to split-horizon simple.
779: <li>Correctly parse "0/0" as the default route when specifying
780: the classless-[ms-]static-routes options in <a
781: href="https://man.openbsd.org/dhcpd.conf">dhcpd.conf(5)</a>.
782: <li>Allowed <a
783: href="https://man.openbsd.org/dhclient">dhclient(8)</a> configuration
784: of <a href="https://man.openbsd.org/carp">carp(4)</a> interfaces.

824: nonsensical address (allowing use of ::1), and try to connect to the
825: address immediately.
826: <li>Implemented a df subcommand for <a
827: href="https://man.openbsd.org/snmp">snmp(1)</a> which outputs disk and

1599: <h3>Notes about the source code</h3>
1600: <p>
1601: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1602: This file contains everything you need except for the kernel sources,
1603: which are in a separate archive.
1604: To extract:
1605: <blockquote><pre>
1606: # <kbd>mkdir -p /usr/src</kbd>
1607: # <kbd>cd /usr/src</kbd>
1608: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1609: </pre></blockquote>
1610: <p>
1611: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1612: This file contains all the kernel sources you need to rebuild kernels.
1613: To extract:
1614: <blockquote><pre>
1615: # <kbd>mkdir -p /usr/src/sys</kbd>
1616: # <kbd>cd /usr/src</kbd>
1617: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1618: </pre></blockquote>
1619: <p>
1620: Both of these trees are a regular CVS checkout. Using these trees it
1621: is possible to get a head-start on using the anoncvs servers as
1622: described <a href="anoncvs.html">here</a>.
1623: Using these files
1624: results in a much faster initial CVS update than you could expect from
1625: a fresh checkout of the full OpenBSD source tree.

1631: <h3>Ports Tree</h3>
1632: <p>
1633: A ports tree archive is also provided. To extract:
1634: <blockquote><pre>
1635: # <kbd>cd /usr</kbd>
1636: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1637: </pre></blockquote>
1638: <p>
1639: Go read the <a href="faq/ports/index.html">ports</a> page
1640: if you know nothing about ports
1641: at this point. This text is not a manual of how to use ports.
1642: Rather, it is a set of notes meant to kickstart the user on the
1643: OpenBSD ports system.
1644: <p>
1645: The <i>ports/</i> directory represents a CVS checkout of our ports.
1646: As with our complete source tree, our ports tree is available via
1647: <a href="anoncvs.html">AnonCVS</a>.
1648: So, in order to keep up to date with the -stable branch, you must make
1649: the <i>ports/</i> tree available on a read-write medium and update the tree
1650: with a command like:
1651: <blockquote><pre>
1652: # <kbd>cd /usr/ports</kbd>
1653: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_6_7</kbd>
1654: </pre></blockquote>
1655: <p>
1656: [Of course, you must replace the server name here with a nearby anoncvs
1657: server.]
1658: <p>
1659: Note that most ports are available as packages on our mirrors. Updated
1660: ports for the 6.7 release will be made available if problems arise.
1661: <p>
1662: If you're interested in seeing a port added, would like to help out, or just
1663: would like to know more, the mailing list
1664: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
