Bluetooth: Move HCI socket definitions into its own header file

2014-07-11T10:53:04+00:00

All the HCI sockets and ioctl based definitions have been in a global
header file that also includes all the HCI protocol structures. To
make this a bit cleaner, move them into its own file.

This also adjusts fs/compat_ioctl.c to only include this new file
and not all the protocol structures that are not needed.

fs/compat: convert to COMPAT_SYSCALL_DEFINE with changing parameter types

2014-03-06T15:30:44+00:00

Some fs compat system calls have unsigned long parameters instead of
compat_ulong_t.
In order to allow the COMPAT_SYSCALL_DEFINE macro generate code that
performs proper zero and sign extension convert all 64 bit parameters
their corresponding 32 bit counterparts.

compat_sys_io_getevents() is a bit different: the non-compat version
has signed parameters for the "min_nr" and "nr" parameters while the
compat version has unsigned parameters.
So change this as well. For all practical purposes this shouldn't make
any difference (doesn't fix a real bug).
Also introduce a generic compat_aio_context_t type which can be used
everywhere.
The access_ok() check within compat_sys_io_getevents() got also removed
since the non-compat sys_io_getevents() should be able to handle
everything anyway.

fs/compat_ioctl.c: fix an underflow issue (harmless)

2014-01-22T00:19:42+00:00

We cap "nmsgs" at I2C_RDRW_IOCTL_MAX_MSGS (42) but the current code
allows negative values.  It's harmless but it makes my static checker
upset so I've made nsmgs unsigned.

fs/compat_ioctl.c: VIDEO_SET_SPU_PALETTE missing error check

2012-10-25T21:37:53+00:00

The compat ioctl for VIDEO_SET_SPU_PALETTE was missing an error check
while converting ioctl arguments.  This could lead to leaking kernel
stack contents into userspace.

Patch extracted from existing fix in grsecurity.

tty, ioctls -- Add new ioctl definitions for tty flags fetching

2012-10-25T19:07:18+00:00

This patch defines new ioctl codes TIOCGPKT, TIOCGPTLCK,
TIOCGEXCL for fetching pty's packet mode and locking state,
and exclusive mode of tty.

[ No real handlers for the codes though, this will be
  addressed in another patch for easier review and
  bisectability ]
