83 <para>All users are encouraged to consult the release errata before
84 installing &os;. The errata document is updated with
85 <quote>late-breaking</quote> information discovered late in the
86 release cycle or after the release. Typically, it contains
87 information on known bugs, security advisories, and corrections to
88 documentation. An up-to-date copy of the errata for &os;
89 &release.current; can be found on the &os; Web site.</para>
94 <title>What's New</title>
96 <para>This section describes
97 the most user-visible new or changed features in &os;
99 In general, changes described here are unique to the &release.branch;
100 branch unless specifically marked as &merged; features.
103 <para>Typical release note items
104 document recent security advisories issued after
106 new drivers or hardware support, new commands or options,
107 major bug fixes, or contributed software upgrades. They may also
108 list changes to major ports/packages or release engineering
109 practices. Clearly the release notes cannot list every single
110 change made to &os; between releases; this document focuses
111 primarily on security advisories, user-visible changes, and major
112 architectural improvements.</para>

229 <title>Kernel Changes</title>
231 <para>&man.acpi.4; now has basic support for the HPET time counter.</para>
233 <para>The &man.acpi.ibm.4; driver now supports setting the fan control
234 mode to manual or automatic, and adjusting the fan speed if the
235 fan control mode is manual. To enable manual control of the fan speed,
236 the sysctl variable <varname>dev.acpi_ibm.<replaceable>0</replaceable>.fan</varname>
237 needs to be set to zero (manual). This should only be used with
238 extreme precaution, as disabling automatic fan control might
239 overheat the hardware and lead to permanent damage.</para>
241 <para>The &man.apm.4; suspend/resume support has been improved.</para>
243 <para>Security event auditing is now supported in the &os; kernel,
244 and is enabled by the <literal>AUDIT</literal> kernel
245 configuration option. More information can be found in the
246 &man.audit.4; manual page.</para>
248 <para>The <literal>options COMPAT_43</literal> kernel
249 configuration option has been deemed unnecessary and has been
250 removed from <filename>GENERIC</filename> and related kernel
251 configurations. This change may result in a small performance
252 increase for some workloads.</para>
254 <para>The &man.ddb.4; debugger now provides the <literal>show lock</literal>
255 command. If the argument has a valid lock class,
256 this displays various information about the lock and calls a
257 new function pointer in lock_class (lc_ddb_show) to dump class-specific
258 information about the lock as well (such as the owner of a mutex or
259 xlock'ed sx lock). &merged;</para>
261 <para>The &man.ddb.4; debugger now provides the <literal>show sleepq</literal>
262 command. This takes a wait channel as an argument and looks
263 for a sleep queue associated with that wait channel.</para>
265 <para><filename>DEFAULTS</filename> kernel configuration files
266 for each platform have been added. These files contain
267 directives that are implicitly included in all kernel
268 configurations, and generally include basic, mandatory
269 functionality for each platform. &merged;</para>
271 <para>A bug in file descriptor handling such that a simple
272 <literal>close(0); dup(fd)</literal> sequence does not return
273 descriptor <literal>0</literal> in some cases, has been fixed.</para>
275 <para>The &man.firmware.9; subsystem has been added. This
276 subsystem provides a mechanism
277 to load binary data into the kernel via a specially crafted module.
280 <para>The &man.gdb.1; remote debugging interface now supports
281 copying console messages to a remote debugger instance.
282 To enable this, set <literal>debug.gdbcons="1"</literal>
283 in <filename>loader.conf</filename>, enter <literal>boot -d;
284 gdb; step</literal> from the loader prompt,
285 then attach &man.gdb.1; from a remote machine.
286 The sysctl variable <varname>debug.gdbcons</varname> can be
287 used to turn on/off this functionality.</para>
289 <para>&man.hwpmc.4; and &man.pmcstat.8; now support profiling
290 of dynamically loaded kernel modules and
291 shared objects loaded with &man.dlopen.3;.
292 &man.pmcstat.8; can now log over a network socket
293 to a remote host.</para>
295 <para>The &man.random.4; entropy device driver is now MPSAFE.
298 <para>&os; now supports concurrent &man.read.2;/&man.readv.2;
299 access to a file.</para>
301 <para>The experimental CORE process scheduler has been added,
302 enabled with the <literal>options SCHED_CORE</literal> kernel
303 configuration option. It is forked from the &man.sched.ule.4;
305 with a different algorithm for detecting an interactive process.
306 More information can be found in the &man.sched.core.4; manual
309 <para>The <literal>SIGCHLD</literal> signal queuing has been
310 added. For each child process whose status has been changed,
311 a <literal>SIGCHLD</literal> instance is queued. If the signal is still pending,
312 and the process changed status several times, the signal information
313 is updated to reflect the latest process status.
314 There is a loader tunable <varname>kern.sigqueue.queue_sigchild</varname>
315 which can control the behavior, setting it to zero disables the
316 <literal>SIGCHLD</literal> queuing feature.</para>
318 <para arch="amd64,i386">Instead of including all of physical
319 memory in a kernel crash dump, the kernel now defaults to dumping only pages that are
320 actively mapped into kernel virtual memory. A new
321 <varname>debug.minidump</varname> sysctl variable
322 can be used to turn off this behavior when set to zero. &merged;</para>
324 <para>A new sysctl variable <varname>kern.malloc_stats</varname>
325 has been added. This allows exporting of kernel malloc
326 statistics via a binary structure stream.</para>
328 <para>A new sysctl variable <varname>kern.forcesigexit</varname>
329 has been added. This forces a process
330 to sigexit if a trap signal is being held by the current thread or
331 ignored by the current process. It is enabled by default.</para>
333 <para arch="alpha">Support for Linux emulation on the Alpha
334 platform has been removed, due to the lack of a
335 <filename>linux_base</filename> port that both supports the
336 Alpha architecture and is in good working condition.</para>
338 <para>The pcvt(4) driver, an alternative to &man.syscons.4;,
339 has been removed, as it had fallen out of sync with the rest
340 of the kernel.</para>
342 <para>RedZone, a buffer corruption protection for the kernel &man.malloc.9;
343 facility has been implemented. This detects both buffer underflows and
344 overflows at runtime on &man.free.9; and &man.realloc.9;,
345 and prints backtraces from where memory was allocated and from where
346 it was freed. For more details, see the &man.redzone.9; manual page.</para>
348 <para>A new sysctl variable <varname>security.mac.biba.interfaces_equal</varname>
349 which makes all network interfaces be created with the label
350 <literal>biba/equal(equal-equal)</literal>, has been added.
351 This is useful where programs such as &man.dhclient.8; and &man.ppp.8;.
352 which initialize network interfaces do not have any labeling support.
353 This variable is set as <literal>0</literal> (disabled) by default.
356 <para>A new sysctl variable <varname>vm.zone_stats</varname>
357 has been added. This allows to export &man.uma.9; allocator
358 statistics via a binary structure stream.</para>
360 <para>The sysctl variable <varname>hw.pci.do_powerstate</varname>
361 has been changed from a boolean to a range.
362 <literal>0</literal> means no power management,
363 <literal>1</literal> means conservative power management which
364 any device class that has caused problems is added to the watch list,
365 <literal>2</literal> means aggressive power management where
366 any device class that is not fundamental to the system is added to the list,
367 and <literal>3</literal> means power them all down unconditionally.
368 The default is <literal>1</literal>.</para>
370 <para arch="ia64">The <filename>GENERIC</filename> kernel now enables
371 SMP support by default.</para>
373 <para>Sample kernel configuration files
374 <filename>src/sys/<replaceable>arch</replaceable>/conf/MAC</filename>
375 for the Mandatory Access Control framework have been added.</para>
377 <para><varname>POSIX_TIMERS</varname> support has been updated to 200112L.</para>
379 <para>An experimental support for POSIX message queue has been
382 <para>&os; now runs on the Xbox, whose architecture is nearly identical
383 to the i386. For details of the latest development, see
384 <ulink url="http://www.FreeBSD.org/platforms/xbox.html"></ulink>.
388 <title>Boot Loader Changes</title>
390 <para>A new option <option>-S</option>,
391 which allows setting the <filename>boot2</filename>
392 serial console speed in the <filename>/boot.config</filename>
393 file or on the <prompt>boot:</prompt> prompt line,
394 has been added.</para>
396 <para arch="i386,amd64">A new loader tunable
397 <varname>comconsole_speed</varname> to change
398 the serial console speed has been added.
399 If the previous stage boot loader requested a serial console,
400 then the default speed is determined from the current serial port
401 speed. Otherwise it is set to 9600 or the value of
402 the <literal>BOOT_COMCONSOLE_SPEED</literal> kernel option.
405 <!-- Above this line, order boot loader changes by keyword-->
407 <para arch="pc98">A bootable CDROM loader has been implemented
408 for the pc98 platform. &merged;</para>
410 <para arch="i386">A bug in the i386 boot loader, which could
411 cause filesystem corruption if

474 <para>The &man.kbdmux.4; driver has been integrated into &man.syscons.4; and
475 the <devicename>kbd</devicename> device driver.
476 By default &man.syscons.4; will look for the &man.kbdmux.4;
477 keyboard first, and then, if not found, look for any keyboard.
478 Switching to &man.kbdmux.4; can be done at boot time by loading
479 the <literal>kbdmux</literal> kernel module via &man.loader.8;,
480 or at runtime via &man.kldload.8; and releasing the active

844 has been added. This allows the &man.icmp.4;
845 reply to non-local packets to be generated with
846 the IP address the packet came through in.
847 This is useful for routers to show in &man.traceroute.8;
848 the actual path a packet has taken instead of
849 the possibly different return path.</para>
851 <para>A new sysctl variable <varname>net.inet.icmp.quotelen</varname>

853 the quotation of the original packet in an ICMP reply.
854 The minimum of 8 bytes is internally enforced.
855 The maximum quotation is the remaining space in the
856 reply mbuf. This option is added in response to the

865 <para>A new socket option <literal>IP_MINTTL</literal> has been added.
866 This may be used to set the minimum acceptable
867 TTL a packet must have when received on a socket.
868 All packets with a lower TTL are silently dropped.
869 This works on already connected/connecting and
870 listening sockets for RAW, UDP, and TCP. This option
871 is only really useful when set to <literal>255</literal>, preventing packets
872 from outside the directly connected networks reaching
873 local listeners on sockets. Also, this option allows

882 now works for UDP.</para>
884 <para>The TCP bandwidth-delay product limiting feature has
885 been disabled when the RTT is below a certain threshold.
886 This optimization does not make sense on a LAN, as it has
887 trouble figuring out the maximal bandwidth due to the coarse
888 tick granularity. A new sysctl variable
889 <varname>net.inet.tcp.inflight.rttthresh</varname> specifies
890 the threshold in milliseconds below which this feature
891 will disengage. It defaults to 10ms. &merged;</para>

949 to control whether failed components will be disconnected or not.
950 The default value is <literal>1</literal> to preserve the current
951 behavior, and if it is set to <literal>0</literal> such components
952 are not disconnected and the kernel will try to still use them
953 (only the first error will be logged).

1299 as <quote>jemalloc</quote>, was designed to improve the
1300 performance of multi-threaded programs, particularly on SMP
1301 systems, while preserving the performance of single-threaded
1302 programs. Due to the use of different algorithms and data
1303 structures, jemalloc may expose some previously-unknown bugs in
1304 userland code, although most of the &os; base system and common
1305 ports have been tested and/or fixed.</para>
1307 <para>The &man.mdconfig.8; utility now supports producing

1359 printing &man.ipsec.4; protocol statistics if the
1360 kernel was compiled with <literal>FAST_IPSEC</literal>
1361 rather than the KAME IPSEC stack.
1362 Note that the output of <command>netstat -s -p ipsec</command>
1363 differs depending on which stack is compiled into
1364 the kernel since they each keep different statistics. &merged;</para>
1366 <para>The <filename>/etc/nsswitch.conf</filename> file is now
1367 installed statically instead of being generated on every

1392 <para>The &man.pkill.1; utility now supports a
1393 <option>-I</option> flag which works like <option>-i</option>
1394 of &man.rm.1;. When this flag is specified, &man.pkill.1;
1395 will ask for confirmation before sending a signal to
1396 each matching process.</para>
1398 <para>The &man.pkill.1; utility (also known as &man.pgrep.1;) has
1399 been moved from <filename>/usr/bin</filename>
