Handle a case in kern_openat() when vn_open() change file type from
DTYPE_VNODE.
Only acquire locks for O_EXLOCK/O_SHLOCK if file type is still vnode,
since we allow for fcntl(2) to process with advisory locks for
DTYPE_VNODE only. Another reason is that all fo_close() routines need to
check and release locks otherwise.
For O_TRUNC, call fo_truncate() instead of truncating the vnode.

Bring in geom_sched, support for scheduling disk I/O requests

While SPARC V9 allows tininess to be detected either before or after
rounding (impl. dep. #55), the SPARC JPS1 responsible for SPARC64 and
UltraSPARC processors defines that in all cases tininess is detected
before rounding therefore rounding up to the smallest normalized number
should set the underflow flag. This change is needed for using SoftFloat
on sparc64 for reference purposes.
If a file is specifically both included and excluded, then:
* It is not extracted (because it is excluded)
* If it's not present in the archive, then an error is
reported (because the file was requested and not found)
* If it is present in the archive, no error is reported.
Previously, this would always report an error because the
exclusion prevented the entry from matching the inclusion.
Also, tar is now more reluctant to report unmatched inclusions.
Previously, "tar x file1 'file*'" against an archive that contained a
single entry "file1" would match file1 and then report an error for
the second pattern because it wasn't matched. It now considers both
inclusions to be matched and reports no error.
Check that the interface is on the list of cloned interfaces before trying
to remove it to avoid panics in case of two threads trying to remove it in
parallel.
Initialize the virtual memory-related resource limits in a single place.
Previously, one of these limits was initialized in two places to a
different value in each place. Moreover, because an unsigned int was used
to represent the amount of pageable physical memory, some of these limits
were incorrectly initialized on 64-bit architectures. (Currently, this
error is masked by login.conf's default settings.)
Make vm_thread_swapin() and vm_thread_swapout() static.
Plug reference leaks in the link-layer code ("new-arp") that previously
prevented the link-layer entry from being freed.
In both in.c and in6.c (though that code path seems to be basically dead)
plug a reference leak in case of a pending callout being drained.
In if_ether.c consistently add a reference before resetting the callout
and in case we canceled a pending one remove the reference for that.
In the final case in arptimer, before freeing the expired entry, remove
the reference again and explicitly call callout_stop() to clear the active
flag.
In nd6.c:nd6_free() we are only ever called from the callout function and
thus need to remove the reference there as well before calling into
llentry_free().
In if_llatbl.c when freeing entire tables make sure that in case we cancel
a pending callout to remove the reference as well.

According to the manpage, the entries have to be sorted by uid. This is

Add WPA-None support:
* WPA-None requires ap_scan=2:
The major difference between ap_scan=1 (default) and 2 is, that no
IEEE80211_IOC_SCAN* ioctls/functions are called, though, there is a
dependency on those. For example the call to wpa_driver_bsd_scan()
sets the interface UP, this never happens, therefore the interface
must be marked up in wpa_driver_bsd_associate(). IEEE80211_IOC_SSID
also is not called, which means that the SSID has not been set prior
to the IEEE80211_MLME_ASSOC call.
* WPA-None has no support for sequence number updates, it doesn't make
sense to check for replay violations..
* I had some crashes right after the switch to RUN state, issue is
that sc->sc_lastrs was not yet defined.
Fix a few issues related to the legacy 4.4 BSD multicast APIs.
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.

Do as the comment suggests and determine the bus space based on the last

iwn4965_set_txpower() uses maxpwr from EEPROM to calculate the power to

This commit enables partial operation of dummynet with kernels
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.
Rename the ALIGN macro to LINT_ALIGN so it does not clash with machine/param.h
Bump the alignment to 16bytes because lint1 memory allocator is used for

(e.g. clang).
Shift the version of perl used by the release build process over to

Introduce the function kmem_alloc_attr(), which allocates kernel virtual
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
had the wrong type.
Improve the handling of IPv6 configuration in rc.d. The ipv6_enable
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.
