Bluetooth: HCI - Fix info leak via getsockname()

2012-09-19T14:04:51+00:00

[ Upstream commit 3f68ba07b1da811bf383b4b701b129bfcb2e4988 ]

The HCI code fails to initialize the hci_channel member of struct
sockaddr_hci and that for leaks two bytes kernel stack via the
getsockname() syscall. Initialize hci_channel with 0 to avoid the
info leak.

Bluetooth: HCI - Fix info leak in getsockopt(HCI_FILTER)

2012-09-19T14:04:50+00:00

[ Upstream commit e15ca9a0ef9a86f0477530b0f44a725d67f889ee ]

The HCI code fails to initialize the two padding bytes of struct
hci_ufilter before copying it to userland -- that for leaking two
bytes kernel stack. Add an explicit memset(0) before filling the
structure to avoid the info leak.

Bluetooth: Add mgmt events for blacklisting

2011-09-21T15:59:15+00:00

Add management interface events for blocking/unblocking a device.
Sender of the block device command gets cmd complete and other
mgmt sockets get the event. Event is also sent to mgmt sockets when
blocking is done with ioctl, e.g when blocking a device with
hciconfig. This makes it possible for bluetoothd to track status
of blocked devices when a third party block or unblocks a device.

Event sending is handled in mgmt_device_blocked function which gets
called from hci_blacklist_add in hci_core.c. A pending command is
added in mgmt_block_device, so that it can found when sending the
event - the event is not sent to the socket from which the pending
command came. Locks were moved out from hci_core.c to hci_sock.c
and mgmt.c, because locking is needed also for mgmt_pending_add in
mgmt.c.

Bluetooth: Move blacklisting functions to hci_core

2011-06-16T18:19:41+00:00

Move blacklisting functions to hci_core.c, so that they can
be used by both management interface and hci socket interface.

Bluetooth: fix build break on hci_sock.c

2011-02-22T11:43:52+00:00

Linux-next as of 20110217 complains when building for OMAP1.

  LD      vmlinux
`hci_sock_cleanup' referenced in section `.init.text' of net/built-in.o: defined in discarded section `.exit.text' of net/built-in.o
`hci_sock_cleanup' referenced in section `.init.text' of net/built-in.o: defined in discarded section `.exit.text' of net/built-in.o
make: *** [vmlinux] Error 1

A recent patch by Gustavo (Bluetooth: Merge L2CAP and SCO modules
into bluetooth.ko) introduced this by calling the hci_sock_cleanup
function in the error path of bt_init.

Fix this by dropping the __exit marking for hci_sock_cleanup.

Bluetooth: Make hci_send_to_sock usable for management control sockets

2010-12-08T01:03:39+00:00

In order to send data to management control sockets the function should:

  - skip checks intended for raw HCI data and stack internal events
  - make sure RAW HCI data or stack internal events don't go to
    management control sockets

In order to accomplish this the patch adds a new member to the bluetooth
skb private data to flag skb's that are destined for management control
sockets.
