and ipv6_ifconfig_<interface> options have already been deprecated,
these changes do not alter that.
With these changes any value set for ipv6_enable will emit a
warning. In order to avoid a POLA violation for the deprecation
of the option ipv6_enable=NO will still disable configuration
for all interfaces other than lo0. ipv6_enable=YES will not have
any effect, but will emit an additional warning. Support and
warnings for this option will be removed in FreeBSD 10.x.
Consistent with the current code, in order for IPv6 to be configured
on an interface (other than lo0) an ifconfig_<interface>_ipv6
option will have to be added to /etc/rc.conf[.local].
1. Clean up and minor optimizations for the following functions:
ifconfig_up (the ipv6 elements)
ipv6if
ipv6_autoconfif
get_if_var
_ifconfig_getargs
The cleanups generally were to move the "easy" tests earlier in the
functions, and consolidate duplicate code.
2. Stop overloading ipv6_prefer with the ability to disable IPv6
configuration.
3. Remove noafif() which was only ever called from ipv6_autoconfif.
Instead, simplify and integrate the tests into that function, and
convert the test to use is_wired_interface() instead of listing
wireless interfaces explicitly.
4. Integrate backwards compatibility for ipv6_ifconfig_<interface>
into _ifconfig_getargs. This dramatically simplifies the code in
all of the callers, and avoids a lot of other code duplication.
5. In rc.d/netoptions, add code for an ipv6_privacy option to use
RFC 4193 style pseudo-random addresses (this is what windows does
by default, FYI).
6. Add support for the [NO]RTADV options in ifconfig_getargs() and
ipv6_autoconfif(). In the latter, include support for the explicit
addition of [-]accept_rtadv in ifconfig_<interface>_ipv6 as is done
in the current code.
7. In rc.d/netif add a warning if $ipv6_enable is set, and remove
the set_rcvar_obsolete for it. Also remove the latter from
rc.d/ip6addrctl.
8. In /etc/defaults/rc.conf:
Add an example for RTADV configuration.
Set ipv6_network_interfaces to AUTO.
Switch ipv6_prefer to YES. If ipv6_enable is not set this will have
no effect.
Add a default for ipv6_privacy (NO).
9. Document all of this in rc.conf.5.
At least in RELENG_7 this fixes some start problems for some programs
from the ports. It is also more correct, as a jail shall not expect
input (interactivity) from the jail-host.
Revert the current behavior of starting jails in the background and
make it optional only for the start of jails (jail_parallell_start=YES
in rc.conf):
- The stop can not be done in the background, the system needs to wait
until everything is stopped correctly before it can reboot or power
down.
- The start should not be done in parallel by default, this not only
breaks POLA for people comming from RELENG_x, it may also break a
dependency chain with other scripts in the jail-host, which need to
do some stuff after the jails are up and running (e.g. hardlinking
a mysql socket from one jail into another one).

HAST allows to transparently store data on two physically separated machines
connected over the TCP/IP network. HAST works in Primary-Secondary
(Master-Backup, Master-Slave) configuration, which means that only one of the
cluster nodes can be active at any given time. Only Primary node is able to
handle I/O requests to HAST-managed devices. Currently HAST is limited to two
cluster nodes in total.
HAST operates on block level - it provides disk-like devices in /dev/hast/
directory for use by file systems and/or applications. Working on block level
makes it transparent for file systems and applications. There in no difference
between using HAST-provided device and raw disk, partition, etc. All of them
are just regular GEOM providers in FreeBSD.
For more information please consult hastd(8), hastctl(8) and hast.conf(5)
manual pages, as well as http://wiki.FreeBSD.org/HAST.

network_ipv6->rc.d/netif integration:
- $ipv6_enable is now obsolete. Instead, IPv6 is enabled by
default if the kernel supports it, and $ipv6_network_interfaces
is "none" by default. If you want to use IPv6, define
$ipv6_network_interfaces and $ifconfig_xxx_ipv6.
An interface which is in $network_interfaces and not in
$ipv6_network_interfaces will be marked as "inet6
-auto_linklocal ifdisabled" (see ifconfig(8)).
- $ipv6_ifconfig_xxx is renamed to ifconfig_xxx_ipv6 for
consistency with other address families. The old variables
still work but can be removed in the future. Note that
ipv6_ifconfig_xxx="..." should be replaced with
ifconfig_xxx_ipv6="inet6 ...".
- Receiving ICMPv6 Router Advertisement is not automatically
enabled even if there is no manual configuration of IPv6 in
rc.conf. If you want it, define
ifconfig_xxx_ipv6="inet6 ... accept_rtadv".
- The rc.d/ip6addrctl now chooses address selection policy based
on $ipv6_prefer, not $ipv6_enable. The default is
ipv6_prefer=NO.
- $router* and $ipv6_router* are replaced with $routed_* and

- Remove the global jail_<jname>_netmask option as it is only

The last half year I've been working on a replacement TTY layer for the
FreeBSD kernel. The new TTY layer was designed to improve the following:
- Improved driver model:
The old TTY layer has a driver model that is not abstract enough to
make it friendly to use. A good example is the output path, where the
device drivers directly access the output buffers. This means that an
in-kernel PPP implementation must always convert network buffers into
TTY buffers.
If a PPP implementation would be built on top of the new TTY layer
(still needs a hooks layer, though), it would allow the PPP
implementation to directly hand the data to the TTY driver.
- Improved hotplugging:
With the old TTY layer, it isn't entirely safe to destroy TTY's from
the system. This implementation has a two-step destructing design,
where the driver first abandons the TTY. After all threads have left
the TTY, the TTY layer calls a routine in the driver, which can be
used to free resources (unit numbers, etc).
The pts(4) driver also implements this feature, which means
posix_openpt() will now return PTY's that are created on the fly.
- Improved performance:
One of the major improvements is the per-TTY mutex, which is expected
to improve scalability when compared to the old Giant locking.
Another change is the unbuffered copying to userspace, which is both
used on TTY device nodes and PTY masters.
Upgrading should be quite straightforward. Unlike previous versions,
existing kernel configuration files do not need to be changed, except
when they reference device drivers that are listed in UPDATING.
