105421ff81 Merge r247814 from x86 modulo whitespace bug:
Turn on the CTL disable tunable by default.

This will allow GENERIC configurations to boot on small memory boxes, but
not require end users who want to use CTL to recompile their kernel.  They
can simply set kern.cam.ctl.disable=0 in loader.conf.

3a45b4781a Re-enable CTL in GENERIC on i386 and amd64, but turn on the CTL disable
tunable by default.

This will allow GENERIC configurations to boot on small memory boxes, but
not require end users who want to use CTL to recompile their kernel.  They
can simply set kern.cam.ctl.disable=0 in loader.conf.

The eventual solution to the memory usage problem is to change the way
CTL allocates memory to be more configurable, but this should fix things
for small memory situations in the mean time.

UPDATING:		Explain the change in the CTL configuration, and
			how users can enable CTL if they would like to use
			it.

sys/conf/options:	Add a new option, CTL_DISABLE, that prevents CTL
			from initializing.

ctl.c:			If CTL_DISABLE is turned on, don't initialize.

i386/conf/GENERIC,
amd64/conf/GENERIC:	Re-enable device ctl, and add the CTL_DISABLE
			option.

fe138cc2af Disable the ctl driver in GENERIC.
It unfortunately steals a fair chunk of RAM at startup even if it's not
actively used, which prevents FreeBSD VMs of 128MB from successfully
booting and running.

 * -D <destdir>   Log paths relative to <destdir>.
 * -h <hash>      Log digest of type <hash>.
 * -T <tags>      Specify which mtree tags to log.
 * -l <linkflag>  Create hard or symbolic links (allows logging).
 * -U             Install without root privileges (owner, group, mode,
                  and flags can be logged via -M

NOTE: In the interest of compatibility with NetBSD and because it is the
obvious letter, the nearly useless -M option (disable mmap) has been
repurposed.

8f134647ca Switch the entire IPv4 stack to keep the IP packet header
in network byte order. Any host byte order processing is
done in local variables and host byte order values are
never[1] written to a packet.

  After this change a packet processed by the stack isn't
modified at all[2] except for TTL.

  After this change a network stack hacker doesn't need to
scratch his head trying to figure out what is the byte order
at the given place in the stack.

[1] One exception still remains. The raw sockets convert host
byte order before pass a packet to an application. Probably
this would remain for ages for compatibility.

[2] The ip_input() still subtructs header len from ip->ip_len,
but this is planned to be fixed soon.

actual hardware driver for register access.

sdhci_pci implements driver for PCI SDHC controllers using new SDHCI

No kernel config modifications are required, but if you load sdhc

In order to get some sparse technical notes, please refer to:

or to the project branch:
svn://svn.freebsd.org/base/projects/fuse/

refinements. This commit does not came from the branch reintegration
itself because it seems svn is not behaving properly for this functionaly

21d172a3f1 A step in resolving mess with byte ordering for AF_INET. After this change:
- All packets in NETISR_IP queue are in net byte order.
  - ip_input() is entered in net byte order and converts packet
    to host byte order right _after_ processing pfil(9) hooks.
  - ip_output() is entered in host byte order and converts packet
    to net byte order right _before_ processing pfil(9) hooks.
  - ip_fragment() accepts and emits packet in net byte order.
  - ip_forward(), ip_mloopback() use host byte order (untouched actually).
  - ip_fastforward() no longer modifies packet at all (except ip_ttl).
  - Swapping of byte order there and back removed from the following modules:
    pf(4), ipfw(4), enc(4), if_bridge(4).
  - Swapping of byte order added to ipfilter(4), based on __FreeBSD_version
  - __FreeBSD_version bumped.
  - pfil(9) manual page updated.

d6d3f01e0a Merge the projects/pf/head branch, that was worked on for last six months,
into head. The most significant achievements in the new code:

 o Fine grained locking, thus much better performance.
 o Fixes to many problems in pf, that were specific to FreeBSD port.

New code doesn't have that many ifdefs and much less OpenBSDisms, thus
is more attractive to our developers.

projects/pf/head branch. And for reference, here is exact list of

- avoids otherwise unavoidable OFW warnings about failures to open disks
  for which aliases exist but no actual hardware is connected
- avoids issues due to different diskN naming schemes
- aligns us with Solaris

c7e41c8b50 Introduce VOP_UNP_BIND(), VOP_UNP_CONNECT(), and VOP_UNP_DETACH()
operations for setting and accessing vnode's v_socket field.

The operations are necessary to implement proper unix socket handling
on layered file systems like nullfs(5).

This change fixes the long standing issue with nullfs(5) being in that
unix sockets did not work between lower and upper layers: if we bound
to a socket on the lower layer we could connect only to the lower
path; if we bound to the upper layer we could connect only to the
upper path. The new behavior is one can connect to both the lower and
the upper paths regardless what layer path one binds to.

08b68b0e4c A major overhaul of the CARP implementation. The ip_carp.c was started
from scratch, copying needed functionality from the old implemenation
on demand, with a thorough review of all code. The main change is that
interface layer has been removed from the CARP. Now redundant addresses
are configured exactly on the interfaces, they run on.

The CARP configuration itself is, as before, configured and read via
SIOCSVH/SIOCGVH ioctls. A new prefix created with SIOCAIFADDR or
SIOCAIFADDR_IN6 may now be configured to a particular virtual host id,
which makes the prefix redundant.

ifconfig(8) semantics has been changed too: now one doesn't need
to clone carpXX interface, he/she should directly configure a vhid
on a Ethernet interface.

To supply vhid data from the kernel to an application the getifaddrs(8)
function had been changed to pass ifam_data with each address. [1]

The new implementation definitely closes all PRs related to carp(4)
being an interface, and may close several others. It also allows
to run a single redundant IP per interface.

Big thanks to Bjoern Zeeb for his help with inet6 part of patch, for
idea on using ifam_data and for several rounds of reviewing!
