Bluetooth: bnep: Add support for get bnep features via ioctl

2015-04-03T21:21:34+00:00

This is needed if user space wants to know supported bnep features
by kernel, e.g. if kernel supports sending response to bnep setup
control message. By now there is no possibility to know supported
features by kernel in case of bnep. Ioctls allows only to add connection,
delete connection, get connection list, get connection info. Adding
connection if it's possible (establishing network device connection) is
equivalent to starting bnep session. Bnep session handles data queue of
transmit, receive messages over bnep channel. It means that if we add
connection the received/transmitted data will be parsed immediately. In
case of get bnep features we want to know before session start, if we
should leave setup data on socket queue and let kernel to handle with it,
or in case of no setup handling support, if we should pull this message
and handle setup response within user space.

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.
