-
- <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 &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>

- </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

- 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="arm">The &os;/&arch.arm; now

-
- <para role="8.0" arch="powerpc">The &os;/&arch.powerpc; now
- supports kernel core dump.</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>
-
