Remove NVIDIA ioctl bits. They will be provided in a kernel module.

Put an XXX comment here to point somebody in the right direction.

Current uses struct thread *td rather than struct proc *p.

This patch extends the FreeBSD Linux compatibility layer to support
NVIDIA API calls; more specifically, it adds an ioctl() handler for
the range of possible NVIDIA ioctl numbers.

In continuation of early fileop credential changes, modify fo_ioctl() to
accept an 'active_cred' argument reflecting the credential of the thread
initiating the ioctl operation.

- Change fo_ioctl() to accept active_cred; change consumers of the
fo_ioctl() interface to generally pass active_cred from td->td_ucred.
- In fifofs, initialize filetmp.f_cred to ap->a_cred so that the
invocations of soo_ioctl() are provided access to the calling f_cred.
Pass ap->a_td->td_ucred as the active_cred, but note that this is
required because we don't yet distinguish file_cred and active_cred
in invoking VOP's.
- Update kqueue_ioctl() for its new argument.
- Update pipe_ioctl() for its new argument, pass active_cred rather
than td_ucred to MAC for authorization.
- Update soo_ioctl() for its new argument.
- Update vn_ioctl() for its new argument, use active_cred rather than
td->td_ucred to authorize VOP_IOCTL() and the associated VOP_GETATTR().

Have SIOCGIFCONF return all (if any) AF_INET addresses for the
interfaces we encounter. In Linux, all addresses are returned for
which gifconf handlers are installed. This boils down to AF_DECnet
and AF_INET. We care mostly about AF_INET for now. Adding additional
families is simple enough.

Returning the addresses is important for RPC clients to function
properly. Andrew found in some reference code that the logic that
handles the retransmission looks for an interface that's up and has
an AF_INET address. This obviously failed as we didn't return any
addresses at all.

Note also that with this change we don't return interfaces that don't
have AF_INET addresses, whereas before we returned any interface
present in the system. This is in line with what Linux does (modulo
interfaces with only AF_DECnet addresses of course :-)

SMP Lock struct file, filedesc and the global file list.

Seigo Tanimura (tanimura) posted the initial delta.

I've polished it quite a bit reducing the need for locking and
adapting it for KSE.

Locks:

1 mutex in each filedesc
protects all the fields.
protects "struct file" initialization, while a struct file
is being changed from &badfileops -> &pipeops or something
the filedesc should be locked.

1 mutex in each struct file
protects the refcount fields.
doesn't protect anything else.
the flags used for garbage collection have been moved to
f_gcflag which was the FILLER short, this doesn't need
locking because the garbage collection is a single threaded
container.
could likely be made to use a pool mutex.

1 sx lock for the global filelist.

struct file * fhold(struct file *fp);
/* increments reference count on a file */

struct file * fhold_locked(struct file *fp);
/* like fhold but expects file to locked */

struct file * ffind_hold(struct thread *, int fd);
/* finds the struct file in thread, adds one reference and
returns it unlocked */

struct file * ffind_lock(struct thread *, int fd);
/* ffind_hold, but returns file locked */

I still have to smp-safe the fget cruft, I'll get to that asap.

Further fixes related to the interface renaming. Now that we
properly translate the interface name passed to us, make sure
we also translate correctly before we return the list of
interfaces with the SIOCGIFCONF ioctl. It is common to use
the interface names returned by that ioctl in further ioctls,
such as SIOCGIFFLAGS.

Remove linux_ifname as it is no longer used. Also remove
ifname_bsd_to_linux as it cannot be used anymore now that
linux_ifname is removed (was deadcode anyway).

When translating the interface name when "eth?" is given, do not
use the internal index number as the unit number to compare with.
The first ethernet interface in Linux is called "eth0", whereas
our internal index starts wth 1 and is not unique to ethernet
interfaces (lo0 has index 1 for example). Instead, use a function-
local index number that starts with 0 and is incremented only
for ethernet interfaces. This way the unit number will match the
n-th ethernet interface in the system, which is exactly what it
means in Linux.

Deal with a few issues that cropped up following the recent changes
to the code for translating socket and private ioctls:

- Only perform socket ioctl translation if the file descriptor is a
socket.
- Treat socket ioctls on non-sockets specially, and for now assume
that these are directed at a tap/vmnet device, so translate the
ioctl numbers as appropriate (the way if_tap abuses some socket
ioctls to pass non-ifreq data is utterly bogus, but this is how
VMware on FreeBSD has always "worked"; I will deal with this
later).
- Add (untested) support for translating SIOCSIFADDR.
- In all cases where we fail to translate an ioctl, return ENOIOCTL
so that other handlers have a chance to do the translation.

This should fix the "/dev/vmnet1: Invalid argument" errors that
users of VMware were experiencing, though I have only verified this
on RELENG_4.

Fix Alpha related brokenness. We used to have a MD linux_ioctl.h
that appeared to be very different from the MI version. These
differences were mostly bogus and caused by copying octal
definitions and write them as hexadecimal values without doing
any base conversion (ie 010 was copied to 0x10). After filtering
out these differences, any remaining (real) incompatibilities
have been merged into the MI header file to make them more visible.

While here, fix the termios <-> termio conversion WRT to the c_cc
field for Alpha. The termios values do not match the termio values
and thus prevents us from copying.

By eliminating the Alpha MD copy of linux_ioctl.h we also fixed
the recent build breakage caused by putting new bits in the MI
header and not in the MD header.

Try to make Linux socket ioctls work. Up until now they've only *pretended*
to work, but haven't really due to subtle differences in structs etc.

This is still not perfect (some ioctls are still known not to work, while
others haven't been tested at all), but it's enough to get Debian's ifconfig
to produce relatively sane output.

More work will be needed to get all ioctls (or at least a reasonable subset)
working, and to support the Cisco Aironet config tool mentioned in the PR.
