IPv4 addresses can and do change during normal operation. Testing by
pfSense developers exposed an issue where OpenOSPFD was using the IPv4
address to leave the OSPF link-scope multicast groups on a dynamic
OpenVPN tun interface, rather than using RFC 3678 with the interface
index, which won't be raced when the interface's addresses change.
In inp_join_group():
If we are already a member of an ASM group, and IP_ADD_MEMBERSHIP or
MCAST_JOIN_GROUP ioctls are re-issued, return EADDRINUSE as per the
legacy 4.4BSD multicast API. This bends RFC 3678 slightly, but does
not violate POLA for apps using the old API.
It also stops us falling through to kicking IGMP state transactions
in what is otherwise a no-op case.
[This has already been dealt with in HEAD, but make it explicit before
we MFC the change to 8.]
In inp_leave_group():
Fix a bogus conditional.
Move the ifp null check to ioctls MCAST_LEAVE* in the switch..case
where it actually belongs.
If an interface was specified, by primary IPv4 address, for ioctl
IP_DROP_MEMBERSHIP or MCAST_LEAVE_GROUP (an ASM full leave operation),
then and only then should we look up the ifp from the IPv4 address in
mreqs.imr_interface.
If not, we fall through to imo_match_group() as before, but only in
the IP_DROP_MEMBERSHIP case.
With these changes, the legacy 4.4BSD multicast API idempotence should
be mostly preserved in the SSM enabled IPv4 stack.

StarCat systems which provides time-of-day services for both as well as
console service for Serengeti, i.e. Sun Fire V1280. While the latter is
described with a device type of serial in the OFW device tree, it isn't
actually an UART. Nevertheless the console service is handled by uart(4)
as this allowed to re-use quite a bit of MD and MI code. Actually, this
idea is stolen from Linux which interfaces the sun4v hypervisor console
with the Linux counterpart of uart(4).
bus we actually mapped at rather than always based on the last bus we
encountered while moving upward in the tree. Otherwise we might use the
wrong bus space in case the bridge directly underneath the nexus doesn't
require mapping, i.e. was skipped as it's the case for ssm(4) nodes.
set, it make sense to actually initialize that array. This fixes some
issues with 4965 adapters where the TX power is crucial.
This got lost somewhere while merging with the OpenBSD code.

* Enable DC calibration and crystal calibration on Centrino Advanced-N
6250 parts.
* Workaround for a HW bug (does not affect 4965AGN) that may sporadically
affect latency under some rare circumstances. From a similar commit to
iwlwifi.
* Update sensitivity settings for 5000 series to workaround a performance
bug in the DSP (1000 is not affected so we keep the old values for 5000).
* Update sensitivity settings for 6000 series.
* Set differential gains on 6250 too (but use a 1.0 factor, not 1.5).
* Init OFDM sensitivity with min value (which depends on the chip)
instead of hardcoding it to 90.
* Read calibration version from ROM and set IWN_GP_DRIVER_CALIB_VER6

compiled with "options VIMAGE".
As it is now, there is still a single instance of the pipes,
and it is only usable from vnet0 (the main instance).
Trying to use a pipe from a different vimage does not crash
the system as it did before, but the traffic coming out from
the pipe goes to the wrong place, and i still need to
figure out where.
Support for per-vimage pipes is almost there (just a matter of
uncommenting the VNET_* definitions for dn_cfg, plus putting into
the structure the remaining static variables), however i need
first to figure out how init/uninit work, and also to understand
where packets are ending up on exit from a pipe.
In summary: vimage support for dummynet is not complete yet,
but we are getting there.
Bump the alignment to 16bytes because lint1 memory allocator is used for
objects that require 16bytes alignment on amd64 (ie. val_t). This makes
lint1 work when compiled with compiler(s) that use SSE for memcpy on amd64.

memory with the specified physical attributes. In particular, like
kmem_alloc_contig(), the caller can specify the physical address range
from which the physical pages are allocated and the memory attributes
(i.e., cache behavior) for these physical pages. However, in contrast to
kmem_alloc_contig() or contigmalloc(), the physical pages that are
allocated by kmem_alloc_attr() are not necessarily physically contiguous.
This function is needed by DRM and VirtualBox.
Correct an error in the prototype for kmem_malloc(). The third argument

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.

VLAN HWFILTER from being used by default, this breaks
stacked pseudo devices, and as it turns out, also breaks
virtual machines that happen to use VLANS (didn't know that
before :). Put the fix back into the em driver, and for good
measure add the same code to the igb driver where it should
have been anyway.
