7e8cc2bd03 Some libstand/bootp.c extension (written by Danny Braniss, slightly
revised/modified by me) to store dhcp options into kenv variables,
so the information is available to the boot loader and can be used
to customize the boot process.

The change is totally unintrusive, essentially made of a single
function to be called while parsing a dhcp response, and a couple
of tables to classify options.  The values extracted from dhcp
options are stored in the kenv environment in one of these forms:

 + options whose name and type is known are saved as
        dhcp.name = value     (string, or number/ip addresses lists)

 + unknown options are assumed to be strings and saved as
        dhcp.option-NNN = "value"

 + options listed as '__INDIR' and sent on the wire as e.g.
        option unknown-252 "some.name=the actual value"
   are saved as
        some.name = "the actual value"

 + options listed as '__ILIST' and sent on the wire as e.g.
        option unknown-249 "a.b=foo bar; c.d= 123; e.f=done"
   are saved as multiple values
        a.b="foo bar"
        c.d="123"
        e.f="done"

As you can see there is quite a bit of flexibility on what can
be passed to the loader or the kernel.

For the time being the vendor-specific table is mostly disabled,
because there is no standard set of options for FreeBSD, and I don't
know all the pxe-specific vendor options.

Also, applications using libstand may live in memory-constrained
environments, so it makes sense to keep these tables as small as
possible, especially considering that one can generate arbitrary
name=value pairs using site-specific options of type __INDIR or
__ILIST (there are 4 __ILIST and 5 __INDIR in the table, numbered
246..249 and 250..254).

Actually, considering that probably 75% of the standard dhcp options
are totally useless, it might make sense to remove them as well.

43151ee6cf Merge user/peter/kinfo branch as of r185547 into head.
This changes struct kinfo_filedesc and kinfo_vmentry such that they are
same on both 32 and 64 bit platforms like i386/amd64 and won't require
sysctl wrapping.

Two new OIDs are assigned.  The old ones are available under
COMPAT_FREEBSD7 - but it isn't that simple.  The superceded interface
was never actually released on 7.x.

The other main change is to pack the data passed to userland via the
sysctl.  kf_structsize and kve_structsize are reduced for the copyout.
If you have a process with 100,000+ sockets open, the unpacked records
require a 132MB+ copyout.  With packing, it is "only" ~35MB.  (Still
seriously unpleasant, but not quite as devastating).  A similar problem
exists for the vmentry structure - have lots and lots of shared libraries
and small mmaps and its copyout gets expensive too.

My immediate problem is valgrind.  It traditionally achieves this
functionality by parsing procfs output, in a packed format.  Secondly, when
tracing 32 bit binaries on amd64 under valgrind, it uses a cross compiled
32 bit binary which ran directly into the differing data structures in 32
vs 64 bit mode.  (valgrind uses this to track file descriptor operations
and this therefore affected every single 32 bit binary)

I've added two utility functions to libutil to unpack the structures into
a fixed record length and to make it a little more convenient to use.

97df383415 Invoke _rtld_atfork_post earlier, before we reinitialize rtld locks
by switching into single-thread mode.

libthr ignores broken use of lock bitmaps used by default rtld locking
implementation, this in turn turns lock handoff in _rtld_thread_init
into NOP. This in turn makes child processes of forked multi-threaded
programs to run with _thr_signal_block still in effect, with most
signals blocked.

413628a7e3 MFp4:
Bring in updated jail support from bz_jail branch.

This enhances the current jail implementation to permit multiple
addresses per jail. In addtion to IPv4, IPv6 is supported as well.
Due to updated checks it is even possible to have jails without
an IP address at all, which basically gives one a chroot with
restricted process view, no networking,..

SCTP support was updated and supports IPv6 in jails as well.

Cpuset support permits jails to be bound to specific processor
sets after creation.

Jails can have an unrestricted (no duplicate protection, etc.) name
in addition to the hostname. The jail name cannot be changed from
within a jail and is considered to be used for management purposes
or as audit-token in the future.

DDB 'show jails' command was added to aid debugging.

Proper compat support permits 32bit jail binaries to be used on 64bit
systems to manage jails. Also backward compatibility was preserved where
possible: for jail v1 syscalls, as well as with user space management
utilities.

Both jail as well as prison version were updated for the new features.
A gap was intentionally left as the intermediate versions had been
used by various patches floating around the last years.

Bump __FreeBSD_version for the afore mentioned and in kernel changes.

Special thanks to:
- Pawel Jakub Dawidek (pjd) for his multi-IPv4 patches
  and Olivier Houchard (cognet) for initial single-IPv6 patches.
- Jeff Roberson (jeff) and Randall Stewart (rrs) for their

cb5c4b10ba Add two rtld exported symbols, _rtld_atfork_pre and _rtld_atfork_post.
Threading library calls _pre before the fork, allowing the rtld to
lock itself to ensure that other threads of the process are out of
dynamic linker. _post releases the locks.

This allows the rtld to have consistent state in the child. Although
child may legitimately call only async-safe functions, the call may
need plt relocation resolution, and this requires working rtld.

0cfab8ddc1 - Add support for PMCs in Intel CPUs of Family 6, model 0xE (Core Solo
and Core Duo), models 0xF (Core2), model 0x17 (Core2Extreme) and
  model 0x1C (Atom).

  In these CPUs, the actual numbers, kinds and widths of PMCs present
  need to queried at run time.  Support for specific "architectural"
  events also needs to be queried at run time.

  Model 0xE CPUs support programmable PMCs, subsequent CPUs
  additionally support "fixed-function" counters.

- Use event names that are close to vendor documentation, taking in
  account that:
  - events with identical semantics on two or more CPUs in this family
    can have differing names in vendor documentation,
  - identical vendor event names may map to differing events across
    CPUs,
  - each type of CPU supports a different subset of measurable
    events.

  Fixed-function and programmable counters both use the same vendor
  names for events.  The use of a class name prefix ("iaf-" or
  "iap-" respectively) permits these to be distinguished.

- In libpmc, refactor pmc_name_of_event() into a public interface
  and an internal helper function, for use by log handling code.

- Minor code tweaks: staticize a global, freshen a few comments.

a1b5a8955e Mark uname(), getdomainname() and setdomainname() with COMPAT_FREEBSD4.
Looking at our source code history, it seems the uname(),
getdomainname() and setdomainname() system calls got deprecated
somewhere after FreeBSD 1.1, but they have never been phased out
properly. Because we don't have a COMPAT_FREEBSD1, just use
COMPAT_FREEBSD4.

Also fix the Linuxolator to build without the setdomainname() routine by
just making it call userland_sysctl on kern.domainname. Also replace the
setdomainname()'s implementation to use this approach, because we're
duplicating code with sysctl_domainname().

I wasn't able to keep these three routines working in our
COMPAT_FREEBSD32, because that would require yet another keyword for
syscalls.master (COMPAT4+NOPROTO). Because this routine is probably
unused already, this won't be a problem in practice. If it turns out to
be a problem, we'll just restore this functionality.

31cfde7132 Like many other functions that handle sockaddrs, realhostname_sa() takes a
struct sockaddr * that it casts internally to the appropriate type based on
sa_family.  However, struct sockaddr has very lax alignment requirements,
which causes the compiler to complain when you cast a struct sockaddr * to,
say, a struct sockaddr_in6 *.

I find it reasonable to assume that the pointer we received is in fact
correctly aligned.  Therefore, we can work around the compiler warnings by
casting to void * before casting to the desired type.  For readability's
sake, this is done with macros.

The same technique should prove useful in other parts of the tree that
deal with socket addresses.

eabe30fc9c Bring in USB4BSD, Hans Petter Selasky rework of the USB stack
that includes significant features and SMP safety.

This commit includes a more or less complete rewrite of the *BSD USB
stack, including Host Controller and Device Controller drivers and
updating all existing USB drivers to use the new USB API:

1) A brief feature list:

  - A new and mutex enabled USB API.

  - Many USB drivers are now running Giant free.

  - Linux USB kernel compatibility layer.

  - New UGEN backend and libusb library, finally solves the "driver
    unloading" problem. The new BSD licensed libusb20 library is fully
    compatible with libusb-0.1.12 from sourceforge.

  - New "usbconfig" utility, for easy configuration of USB.

  - Full support for Split transactions, which means you can use your
    full speed USB audio device on a high speed USB HUB.

  - Full support for HS ISOC transactions, which makes writing drivers
    for various HS webcams possible, for example.

  - Full support for USB on embedded platforms, mostly cache flushing
    and buffer invalidating stuff.

  - Safer parsing of USB descriptors.

  - Autodetect of annoying USB install disks.

  - Support for USB device side mode, also called USB gadget mode,
    using the same API like the USB host side. In other words the new
    USB stack is symmetric with regard to host and device side.

  - Support for USB transfers like I/O vectors, means more throughput
    and less interrupts.

  - ... see the FreeBSD quarterly status reports under "USB project"

2) To enable the driver in the default kernel build:

2.a) Remove all existing USB device options from your kernel config
file.

2.b) Add the following USB device options to your kernel configuration
file:

# USB core support
device          usb2_core

# USB controller support
device		usb2_controller
device		usb2_controller_ehci
device		usb2_controller_ohci
device		usb2_controller_uhci

# USB mass storage support
device		usb2_storage
device		usb2_storage_mass

# USB ethernet support, requires miibus
device		usb2_ethernet
device		usb2_ethernet_aue
device		usb2_ethernet_axe
device		usb2_ethernet_cdce
device		usb2_ethernet_cue
device		usb2_ethernet_kue
device		usb2_ethernet_rue
device		usb2_ethernet_dav

# USB wireless LAN support
device		usb2_wlan
device		usb2_wlan_rum
device		usb2_wlan_ral
device		usb2_wlan_zyd

# USB serial device support
device		usb2_serial
device		usb2_serial_ark
device		usb2_serial_bsa
device		usb2_serial_bser
device		usb2_serial_chcom
device		usb2_serial_cycom
device		usb2_serial_foma
device		usb2_serial_ftdi
device		usb2_serial_gensa
device		usb2_serial_ipaq
device		usb2_serial_lpt
device		usb2_serial_mct
device		usb2_serial_modem
device		usb2_serial_moscom
device		usb2_serial_plcom
device		usb2_serial_visor
device		usb2_serial_vscom

# USB bluetooth support
device		usb2_bluetooth
device		usb2_bluetooth_ng

# USB input device support
device		usb2_input
device		usb2_input_hid
device		usb2_input_kbd
device		usb2_input_ms

# USB sound and MIDI device support
device		usb2_sound

2) To enable the driver at runtime:

2.a) Unload all existing USB modules. If USB is compiled into the
kernel then you might have to build a new kernel.

2.b) Load the "usb2_xxx.ko" modules under /boot/kernel having the same
base name like the kernel device option.

a9148abd9d Implement support for RPCSEC_GSS authentication to both the NFS client
and server. This replaces the RPC implementation of the NFS client and
server with the newer RPC implementation originally developed
(actually ported from the userland sunrpc code) to support the NFS
Lock Manager.  I have tested this code extensively and I believe it is
stable and that performance is at least equal to the legacy RPC
implementation.

The NFS code currently contains support for both the new RPC
implementation and the older legacy implementation inherited from the
original NFS codebase. The default is to use the new implementation -
add the NFS_LEGACYRPC option to fall back to the old code. When I
merge this support back to RELENG_7, I will probably change this so
that users have to 'opt in' to get the new code.

To use RPCSEC_GSS on either client or server, you must build a kernel
which includes the KGSSAPI option and the crypto device. On the
userland side, you must build at least a new libc, mountd, mount_nfs
and gssd. You must install new versions of /etc/rc.d/gssd and
/etc/rc.d/nfsd and add 'gssd_enable=YES' to /etc/rc.conf.

As long as gssd is running, you should be able to mount an NFS
filesystem from a server that requires RPCSEC_GSS authentication. The
mount itself can happen without any kerberos credentials but all
access to the filesystem will be denied unless the accessing user has
a valid ticket file in the standard place (/tmp/krb5cc_<uid>). There
is currently no support for situations where the ticket file is in a
different place, such as when the user logged in via SSH and has
delegated credentials from that login. This restriction is also
present in Solaris and Linux. In theory, we could improve this in
future, possibly using Brooks Davis' implementation of variant
symlinks.

Supporting RPCSEC_GSS on a server is nearly as simple. You must create
service creds for the server in the form 'nfs/<fqdn>@<REALM>' and
install them in /etc/krb5.keytab. The standard heimdal utility ktutil
makes this fairly easy. After the service creds have been created, you
can add a '-sec=krb5' option to /etc/exports and restart both mountd
and nfsd.

The only other difference an administrator should notice is that nfsd
doesn't fork to create service threads any more. In normal operation,
there will be two nfsd processes, one in userland waiting for TCP
connections and one in the kernel handling requests. The latter
process will create as many kthreads as required - these should be
visible via 'top -H'. The code has some support for varying the number
of service threads according to load but initially at least, nfsd uses
a fixed number of threads according to the value supplied to its '-n'
option.

b8cbf1a36a Remove unneeded call to revoke() inside openpty().
As discussed on the commits list, there is no need to call revoke()
inside openpty(). On RELENG_6 and RELENG_7 unlockpt() will call
revoke(). On HEAD we create pseudo-terminals on demand, so there is no
need to revoke the slave device node.

This change should never be MFC'd, because the implementation we have in
RELENG_6 and RELENG_7 should work flawlessly with older versions of
libc.

16511f59a9 Remove doubtful structure definition with variable array members.
I believe this is not a valid C99 construct.  Use directly calculated
offsets into the supplied buffer, using specified members length,
to fill appropriate structure.

Either use sysctl, or copy the value of the UNAME_x environment
variable, instead of unconditionally doing sysctl, and then
overriding a returned value with user-specified one.
