We're very lucky, because the flags used by our TIOCPKT implementation
are the same as flags used by Linux. We can safely enable TIOCPKT,
assuming EXTPROC is not used.
TIOCSPTLCK is used by unlockpt(). Because we don't need unlockpt() in
our implementation, make this ioctl a no-op.

LINUX_SIOCGIFCOUNT just returns 0 since it is not implemented in the
Linux 2.6.16.
LINUX_SIOCGIFINDEX/LINUX_SIOGIFINDEX are mapped to the FreeBSD native
SIOCGIFINDEX.

Linux SCSI SG passthrough device API. The intention is to allow for both
running of Linux apps that want to talk to /dev/sg* nodes, and to facilitate
porting of apps from Linux to FreeBSD. As such, both native and linuxolator
entry points and definitions are provided.
Caveats:
- This does not support the procfs and sysfs nodes that the Linux SG
driver provides. Some Linux apps may rely on these for operation,
others may only use them for informational purposes.
- More ioctls need to be implemented.
- Linux uses a naming scheme of "sg[a-z]" for devices, while FreeBSD uses a
scheme of "sg[0-9]". Devfs aliasis (symlinks) are automatically created
to link the two together. However, tools like camcontrol only see the
native names.
- Some operations were originally designed to return byte counts or other
data directly as the syscall return value. The linuxolator doesn't appear
to support this well, so this driver just punts for these cases.
Now that the driver is in place, others are welcome to add missing
functionality. Thanks to Roman Divacky for pushing this work along.
linux_ioctl.[ch] : Implement LINUX_TIOCGPTN, which returns the pty number
linux_stats.c :
- Return the magic number for devfs.
- In various stats()-related functions, check that we're stating a
file in /dev/pts, and if so, change the st_rdev field to match what linux
expects to be there for a slave pty device. The glibc checks for this, and
their openpty() fails if it is no correct.
I've had this sitting in my tree for a long time and I can't seem to
find who sent it to me in the first place, apologies to whoever is
missing out on a Contributed by: line here.
I belive it works as it should.
- add wrappers for mmap2(2) and ftruncate64(2) system calls;
- don't spam console with printf's when VFAT_READDIR_BOTH ioctl(2) is invoked;
- add support for SOUND_MIXER_READ_STEREODEVS ioctl(2);
- make msgctl(IPC_STAT) and IPC_SET actually working by converting from
BSD msqid_ds to Linux and vice versa;
- properly return EINVAL if semget(2) is called with nsems being negative.

NVIDIA API calls; more specifically, it adds an ioctl() handler for
the range of possible NVIDIA ioctl numbers.
Submitted by: Christian Zander <zander@minion.de>
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.

Add some missing break statements in the socket ioctl switch.
Check the return value from copyin() / copyout().
Fix some disorderings and misindentations.
Support a couple more socket ioctls.
Add missing break statements.
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.
Also slightly change the name translation policy - only rename interfaces
that have the IFF_BROADCAST flag set. This is not perfect, but is closer to
how Linux names network interfaces.
Other modules can register and unregister ioctl handlers to extend the
ioctls known by the Linuxulator. A recent application is the vmware
port. The Linuxulator itself uses the new interface to register its
handlers as well. Handlers for the following types of ioctls have been
defined:
cdrom
console (=keyboard and VT handling)
socket
sound
termio
All ioctl related defines and declarations have been moved to a new
file (linux_ioctl.h), except for the pluggable ioctl handler interface
definition.
While there, cleanup linux.h some more.
linux.h and linux_ioctl.[ch] have been made to conform to style(9) as
much as possible.
