- <title>What's New</title>
-
- <para>This section describes
- the most user-visible new or changed features in &os;
- since &release.prev;.
- In general, changes described here are unique to the &release.branch;
- branch unless specifically marked as &merged; features.
- </para>
-
- <para>Typical release note items
- document recent security advisories issued after
- &release.prev;,
- new drivers or hardware support, new commands or options,
- major bug fixes, or contributed software upgrades. They may also
- list changes to major ports/packages or release engineering
- practices. Clearly the release notes cannot list every single
- change made to &os; between releases; this document focuses
- primarily on security advisories, user-visible changes, and major
- architectural improvements.</para>

- <title>Kernel Changes</title>
-
- <para>A new &man.cpuset.2; API has been added
- for thread to CPU binding and CPU resource grouping and
- assignment. The &man.cpuset.1; userland utility has been added
- to allow manipulation of processor sets.</para>
-
- <para role="merged">The &man.ddb.4; kernel debugger now has an output
capture
- facility. Input and output from &man.ddb.4; can now be captured
- to a memory buffer for later inspection using &man.sysctl.8; or
- a textdump. The new <command>capture</command> command controls
- this feature.</para>
-
- <para role="merged">The &man.ddb.4; debugger now supports a simple
scripting
- facility, which supports a set of named scripts consisting of a
- set of &man.ddb.4; commands. These commands can be managed from
- within &man.ddb.4; or with the use of the new &man.ddb.8;
- utility. More details can be found in the &man.ddb.4; manual
- page.</para>
-
- <para role="merged">The kernel now supports a new textdump format of kernel
- dumps. A textdump provides higher-level information via
- mechanically generated/extracted debugging output, rather than a
- simple memory dump. This facility can be used to generate brief
- kernel bug reports that are rich in debugging information, but
- are not dependent on kernel symbol tables or precisely
- synchronized source code. More information can be found in the
- &man.textdump.4; manual page.</para>
-
- <para>Kernel support for M:N threading has been removed. While
- the KSE (Kernel Scheduled Entities) project was quite successful
- in bringing threading to FreeBSD, the M:N approach taken by the
- KSE library was never developed to its full potential.
- Backwards compatibility for applications using KSE threading
- will be provided via &man.libmap.conf.5; for dynamically linked
- binaries. The &os; Project greatly appreciates the work of
- &a.julian;, &a.deischen;, and &a.davidxu; on KSE support.</para>
-
- <para>The &os; kernel now exports information about certain kernel
- features via the <varname>kern.features</varname> sysctl tree.
- The &man.feature.present.3; library call provides a convenient
- interface for user applications to test the presence of
- features.</para>
-
- <para arch="amd64">The &os; kernel now has support for large
- memory page mappings (<quote>superpages</quote>).</para>
-
- <para arch="amd64,i386,ia64,powerpc" role="merged">The ULE
- scheduler is now the default process scheduler
- in <filename>GENERIC</filename> kernels.</para>
-
- <sect3 id="boot">
- <title>Boot Loader Changes</title>
-
- <para arch="amd64,i386" role="merged">The BTX kernel used by the boot
- loader has been changed to invoke BIOS routines from real
- mode. This change makes it possible to boot &os; from USB
- devices.</para>
-
- <para arch="amd64,i386" role="merged">A new gptboot boot loader has
- been added to support booting from a GPT labeled disk. A
- new <command>boot</command> command has been added to
- &man.gpt.8;, which makes a GPT disk bootable by writing the
- required bits of the boot loader, creating a new boot
- partition if required.</para>

+
+ <para role="8.0">The &os; <filename>GENERIC</filename> kernel now
+ includes Trusted BSD MAC (Mandatory Access Control) support.
+ No MAC policy module is loaded by default.</para>
+
+ <para role="8.0" arch="i386">A loader
+ tunable <varname>hw.clflush_disable</varname> has been added
+ to avoid panic (trap 9)
+ at <function>map_invalidate_cache_range()</function> even if
+ Intel CPU is used. This tunable can be set
+ to <literal>-1</literal> (default), <literal>0</literal> and
+ <literal>1</literal>. The <literal>-1</literal> is same as
+ the current behavior, which automatically
+ disables <literal>CLFLUSH</literal> on Intel CPUs without
+ <literal>CPUID_SS</literal> (this should occurr on Xen
+ only). You can specify <literal>1</literal> when this panic
+ happens on non-Intel CPUs (such as AMD's). Because disabling
+ <literal>CLFLUSH</literal> can reduce performance, you can try
+ with setting <literal>0</literal> on Intel CPUs
+ without <literal>SS</literal> to
+ use <literal>CLFLUSH</literal> feature.</para>
+
+ <para role="8.0">The &os; newbus subsystem is now MPSAFE.</para>
+
+ <para role="8.0">The &man.jail.8; subsystem has been updated. Changes
include:</para>
+
+ <itemizedlist role="7.2">
+ <listitem>
+ <para role="8.0">A new virtualization container
+ named <quote>vimage</quote> has been implemented. This is
+ not enabled by default. To enable this, add the following
+ kernel options to your kernel configuration file and
+ rebuild the kernel:</para>
+
+ <programlisting>options VIMAGE</programlisting>
+
+ <para>Note that <literal>options SCTP</literal> in the
+ <filename>GENERIC</filename> kernel is not compatible with
+ <literal>options VIMAGE</literal>. This limitation will
+ be fixed in the next release.</para>
+
+ <para>The vimage is a jail with a virtualized instance of
+ the &os; network stack. It can be created by using
+ &man.jail.8; command like this:</para>
+
+ <screen>&prompt.root; jail -c vnet
name=<replaceable>vnet1</replaceable>
host.hostname=<replaceable>vnet1.example.net</replaceable> path=/
persist</screen>
+
+ <para>The vimage has own loopback interface and a separated
+ network stack including the L3 routing tables. Network
+ interfaces on the system can be moved by using
+ &man.ifconfig.8; <option>vnet</option> option between the
+ different vimage jails and outside of them.</para>
+
+ <para>Furthermore, the &man.epair.4; pseudo-interface driver
+ has been added to help communication between vimage jails.
+ It emulates a pair of back-to-back connected Ethernet
+ interfaces. For example, the following commands create an
+ interface pair of &man.epair.4;:</para>
+
+ <screen>&prompt.root; ifconfig epair0 create
+epair0a
+&prompt.root; ifconfig epair0a
+epair0a: flags=8842<BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu
1500
+ ether 02:c0:64:00:07:0a
+&prompt.root; ifconfig epair0b
+epair0b: flags=8842<BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu
1500
+ ether 02:c0:64:00:08:0b</screen>
+
+ <para>The &man.epair.4; pseudo-interfaces and any physical
+ interfaces on the system can be moved between vimage jails
+ by using &man.ifconfig.8; <option>vnet</option> option as
+ described above. Even after half of an &man.epair.4; pair
+ is moved, the back-to-back connection still valid and can
+ be used for inter-jail communication.</para>
+
+ <para>Note that vimage is still considered as an
+ experimental feature.</para>
+ </listitem>
+
+ <listitem>
+ <para>A jail can now have arbitrary named parameters similar
+ to environmental variables and the fixed jail parameters
+ in the previous releases have been replaced with them.
+ The jail name can now be used for identifying the jail in
+ &man.jexec.8; and &man.killall.1;.</para>
+ </listitem>
+
+ <listitem>
+ <para>Multiple IPv4 and/or IPv6 addresses per jail are now
+ supported. It is even possible to have jails without
+ an IP address at all, which basically gives one a chrooted
+ environment with restricted process view and no
+ networking.</para>
+ </listitem>
+
+ <listitem>
+ <para>SCTP (&man.sctp.4;) with IPv6 in jails has been
+ implemented.</para>
+ </listitem>
+
+ <listitem>
+ <para>Specific CPU binding by using &man.cpuset.1; has been
+ implemented. Note that the current implementation allows
+ the superuser inside of the jail to change the CPU
+ bindings specified.</para>
+ </listitem>
+
+ <listitem>
+ <para>A &man.jail.8; can start with a specific route
+ FIB now.</para>

+ <literal>show jails</literal> subcommand.</para>
+ </listitem>
+
+ <listitem>
+ <para>Compatibility support which permits 32-bit jail
+ binaries to be used on 64-bit systems to manage jails has
+ been added.</para>
+ </listitem>
+
+ <listitem>
+ <para>Note that both version numbers of
+ <literal>jail</literal> and <literal>prison</literal> in
+ the &man.jail.8; have been updated for the new
+ features.</para>
+ </listitem>
+ </itemizedlist>
+
+ <para role="8.0">The &man.ksyms.4;, kernel symbol table
+ interface driver has been added. It creates a character
+ device <filename>/dev/ksyms</filename> and provides
+ read-only access to a snapshot of the kernel symbol
+ table.</para>
+
+ <para role="8.0" arch="amd64,i386">The &os; Linux emulation
+ layer has been updated to version 2.6.16 and the default Linux
+ infrastructure port is
+ <filename>emulators/linux_base-f10</filename> (Fedora
+ 10).</para>
+
+ <para role="8.0" arch="amd64,i386">The &os; virtual memory
+ subsystem now supports fully transparent use of
+ <application>superpages</application> for application memory;
+ application memory pages are dynamically promoted to or
+ demoted from superpages without any modification to
+ application code. This change offers the benefit of large
+ page sizes such as improved virtual memory efficiency and
+ reduced TLB (translation lookaside buffer) misses without
+ downsides like application changes and virtual memory
+ inflexibility. This can be enabled by setting a loader tunable
+ <varname>vm.pmap.pg_ps_enabled</varname> to
+ <literal>1</literal> and is enabled by default on
+ &arch.amd64;.</para>
+
+ <para role="7.2">The &man.ddb.8; kernel debugger now supports a
+ <command>show mount</command> subcommand.</para>
+
+ <para role="7.2">The &os; DTrace subsystem now supports a probe for
+ process execution.</para>
+
+ <para role="7.2" arch="amd64">The &os; kernel virtual address
+ space has been increased to 6GB. This allows subsystems to use
+ larger virtual memory space than before. For example, the
+ &man.zfs.8; adaptive replacement cache (ARC) requires large
+ kernel memory space to cache file system data, so it benefits
+ from the increased address space. Note that the ceiling on
+ the kernel map size is now 60% of the size of physical memory
+ rather than an absolute quantity.</para>
+
+ <para role="7.2">The &man.kld.4; now supports installing 32-bit
+ system calls to the &os; syscall translation layer from kernel
+ modules.</para>
+
+ <para role="7.2">The &man.ktr.4; now supports a new KTR tracepoint in the
+ <literal>KTR_CALLOUT</literal> class to note when a callout
+ routine finishes executing.</para>
+
+ <para role="7.2">Types of variables used to track the amount of allocated
+ System V shared memory have been changed from
+ <literal>int</literal> to <literal>size_t</literal>. This
+ makes it possible to use more than 2 GB of memory for shared
+ memory segments on 64-bit architectures. Please note the new
+ BUGS section in &man.shmctl.2; and
+ <filename>/usr/src/UPDATING</filename> for limitations of this
+ temporary solution.</para>
+
+ <para role="7.2">The &man.sysctl.3; leaf nodes have a flag to tag
+ themselves as MPSAFE now.</para>
+
+ <para role="7.2">The &os; 32-bit system call translation layer now
+ supports installing 32-bit system calls for
+ <literal>VFS_AIO</literal>.</para>
+
+ <para role="7.1">The &man.clock.gettime.2; and the related system calls
now
+ support a clock ID <literal>CLOCK_THREAD_CPUTIME_ID</literal>,
+ as defined in POSIX.</para>
+
+ <para role="7.1">The &man.cpuset.2; system call has been added. This is
an
+ API for thread to CPU binding and CPU resource grouping and
+ assignment.</para>
+
+ <para role="7.1">The DTrace, a comprehensive dynamic tracing framework
and
+ &man.dtrace.1; userland utility have been imported from
+ OpenSolaris. DTrace provides a powerful infrastructure to
+ permit administrators, developers, and service personnel to
+ concisely answer arbitrary questions about the behavior of the
+ operating system and user programs.</para>
+
+ <para role="7.1">The &man.ddb.4; kernel debugger now has an output
capture
+ facility. Input and output from &man.ddb.4; can now be captured
+ to a memory buffer for later inspection using &man.sysctl.8; or
+ a textdump. The new <command>capture</command> command controls
+ this feature.</para>
+
+ <para role="7.1">The &man.ddb.4; debugger now supports a simple scripting
+ facility, which supports a set of named scripts consisting of a
+ set of &man.ddb.4; commands. These commands can be managed from
+ within &man.ddb.4; or with the use of the new &man.ddb.8;
+ utility. More details can be found in the &man.ddb.4; manual
+ page.</para>
+
+ <para role="7.1">The &man.ddb.4; <command>ex</command> command now
supports
+ an <option>/S</option> mode which interprets and prints the
+ value at the requested address as a symbol. For example,
+ <userinput>ex /S <replaceable>aio_swake</replaceable></userinput>
+ prints the name of the function currently registered in
+ via <replaceable>aio_swake</replaceable> hook.</para>
+
+ <para role="7.1">The &man.ddb.4; <command>show conifhk</command> command
has
+ been added. This lists hooks currently waiting for completion
+ in <function>run_interrupt_driven_config_hooks()</function>.</para>
+
+ <para role="7.1">The &man.fcntl.2; system call now supports
+ <literal>F_DUP2FD</literal> command. This is equivalent to
+ &man.dup.2;, and compatible with the Sun Solaris and the IBM
+ AIX.</para>
+
+ <para role="7.1">The &os;'s &man.linux.4; ABI support now implements
+ <function>sched_setaffinity()</function> and
+ <function>sched_getaffinity()</function> using real CPU affinity
+ setting primitives.</para>
+
+ <para role="7.1">The &man.procstat.1; utility has been added. This is a
+ process inspection utility which provides some of the missing
+ functionality from &man.procfs.5; and new functionality for monitoring
+ and debugging specific processes.</para>
+
+ <para role="7.1">The client side functionality of &man.rpc.lockd.8; has
been
+ implemented in the &os; kernel. This implementation provides the
+ correct semantics for &man.flock.2; style locks which are used
+ by the &man.lockf.1; command line tool and the &man.pidfile.3;
+ library. It also implements recovery from server restarts and
+ ensures that dirty cache blocks are written to the server before
+ obtaining locks (allowing multiple clients to use file locking
+ to safely share data). Also, a new kernel option
+ <literal>options NFSLOCKD</literal> has been added and enabled
+ by default. If the kernel support is enabled, &man.rpc.lockd.8;
+ automatically detects and uses the functionality.</para>
+
+ <para role="7.1">The &os; kernel now supports a new textdump format of
kernel
+ dumps. A textdump provides higher-level information via
+ mechanically generated/extracted debugging output, rather than a
+ simple memory dump. This facility can be used to generate brief
+ kernel bug reports that are rich in debugging information, but
+ are not dependent on kernel symbol tables or precisely
+ synchronized source code. More information can be found in the
+ &man.textdump.4; manual page.</para>
+
+ <para role="7.1">The &man.wait4.2; system call now supports
+ <option>WNOWAIT</option> flag to keep the process whose status
+ is returned in a waitable state and <option>WSTOPPED</option>
+ which is equivalent to <option>WUNTRACED</option>.</para>
+
+ <para role="7.1" arch="amd64,i386,sparc64">The &os; kernel now has
+ initial support of binding interrupts to CPUs.</para>
+
+ <para role="7.1" arch="amd64,i386"> The &man.sched.ule.4; scheduler is
now the default
+ process scheduler in <filename>GENERIC</filename>
+ kernels.</para>
+
+ <para role="7.1">The sysctl
+ variables <varname>kern.features.compat_freebsd[456]</varname>
