2007-01-09[Bluetooth] Handle device registration failuresMarcel Holtmann
In the case the device registration for a new Bluetooth low-level connection fails there is no need to unregister it when the temporary data structure has been removed. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2007-01-09[Bluetooth] Fix uninitialized return value for RFCOMM sendmsg()Marcel Holtmann
When calling send() with a zero length parameter on a RFCOMM socket it returns a positive value. In this rare case the variable err is used uninitialized and unfortunately its value is returned. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2007-01-09[Bluetooth] More checks if DLC is still attached to the TTYMarcel Holtmann
If the DLC device is no longer attached to the TTY device, then return errors or default values for various callbacks of the TTY layer. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2007-01-09[Bluetooth] Add packet size checks for CAPI messagesMarcel Holtmann
With malformed packets it might be possible to overwrite internal CMTP and CAPI data structures. This patch adds additional length checks to prevent these kinds of remote attacks. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

2006-12-08[PATCH] tty: switch to ktermiosAlan Cox
This is the grungy swap all the occurrences in the right places patch that goes with the updates. At this point we have the same functionality as before (except that sgttyb() returns speeds not zero) and are ready to begin turning new stuff on providing nobody reports lots of bugs If you are a tty driver author converting an out of tree driver the only impact should be termios->ktermios name changes for the speed/property setting functions from your upper layers. If you are implementing your own TCGETS function before then your driver was broken already and its about to get a whole lot more painful for you so please fix it 8) Also fill in c_ispeed/ospeed on init for most devices, although the current code will do this for you anyway but I'd like eventually to lose that extra paranoia [akpm@osdl.org: bluetooth fix] [mp3@de.ibm.com: sclp fix] [mp3@de.ibm.com: warning fix for tty3270] [hugh@veritas.com: fix tty_ioctl powerpc build] [jdike@addtoit.com: uml: fix ->set_termios declaration] Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Martin Peschke <mp3@de.ibm.com> Acked-by: Peter Oberparleiter <oberpar@de.ibm.com> Cc: Cornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by: Hugh Dickins <hugh@veritas.com> Signed-off-by: Jeff Dike <jdike@addtoit.com> Cc: Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2006-11-21[Bluetooth] Ignore L2CAP config requests on disconnectMarcel Holtmann
Any L2CAP connection in disconnecting state shall not response to any further config requests from the remote side. So in case such a request is received, ignore it. Signed-off-by: Ville Tervo <ville.tervo@nokia.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2006-11-21[Bluetooth] Always include MTU in L2CAP config responsesMarcel Holtmann
When sending a positive config response it shall include the actual MTU to be used on this channel. This differs from the Bluetooth 1.1 specification where it was enough to acknowledge the config request. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2006-11-21[Bluetooth] Check if RFCOMM session is still attached to the TTYMarcel Holtmann

2006-11-21[Bluetooth] Attach low-level connections to the Bluetooth busMarcel Holtmann
To receive uvents for the low-level ACL and SCO links, they must be assigned to a subsystem. It is enough to attach them to the already established Bluetooth bus. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2006-10-20[Bluetooth] Fix HID disconnect NULL pointer dereferenceMarcel Holtmann
The latest HID disconnect sequence change introduced a NULL pointer dereference. For the quirk to handle buggy remote HID implementations, it is enough to wait for a potential control channel disconnect from the remote side and it is also enough to wait only 500 msecs. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2006-10-15[Bluetooth] Add locking for bt_proto array manipulationMarcel Holtmann
The bt_proto array needs to be protected by some kind of locking to prevent a race condition between bt_sock_create and bt_sock_register.

2006-10-15[Bluetooth] Fix reference count when connection lookup failsMarcel Holtmann

2006-10-15[Bluetooth] Disconnect HID interrupt channel firstMarcel Holtmann
The Bluetooth HID specification demands that the interrupt channel shall be disconnected first. This is needed to pass the qualification tests. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2006-10-15[Bluetooth] Support concurrent connect requestsMarcel Holtmann
Most Bluetooth chips don't support concurrent connect requests, because this would involve a multiple baseband page with only one radio. In the case an upper layer like L2CAP requests a concurrent connect these chips return the error "Command Disallowed" for the second request. If this happens it the responsibility of the Bluetooth core to queue the request and try again after the previous connect attempt has been completed. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2006-10-15[Bluetooth] Make use of virtual devices treeMarcel Holtmann
The Bluetooth subsystem currently uses a platform device for devices with no parent. It is a better idea to use the new virtual devices tree for these. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2006-10-15[Bluetooth] Handle return values from driver core functionsMarcel Holtmann
Some return values of the driver core register and create functions are not handled and so might cause unexpected problems. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2006-10-15[Bluetooth] Fix compat ioctl for BNEP, CMTP and HIDPMarcel Holtmann
There exists no attempt do deal with the fact that a structure with a uint32_t followed by a pointer is going to be different for 32-bit and 64-bit userspace. Any 32-bit process trying to use it will be failing with -EFAULT if it's lucky; suffering from having data dumped at a random address if it's not.

2006-10-02[PATCH] const struct tty_operationsJeff Dike
As part of an SMP cleanliness pass over UML, I consted a bunch of structures in order to not have to document their locking. One of these structures was a struct tty_operations. In order to const it in UML without introducing compiler complaints, the declaration of tty_set_operations needs to be changed, and then all of its callers need to be fixed. This patch declares all struct tty_operations in the tree as const. In all cases, they are static and used only as input to tty_set_operations. As an extra check, I ran an i386 allyesconfig build which produced no extra warnings. 53 drivers are affected. I checked the history of a bunch of them, and in most cases, there have been only a handful of maintenance changes in the last six months. serial_core.c was the busiest one that I looked at.

2006-09-28[Bluetooth]: Fix section mismatch of bt_sysfs_cleanup()Arnaud Patard

2006-09-28[Bluetooth]: Don't update disconnect timer for incoming connectionsMarcel Holtmann
In the case of device pairing the only safe method is to establish a low-level ACL link. In this case, the remote side should not use the disconnect timer to give the other side the chance to enter the PIN code. If the disconnect timer is used, the connection will be dropped to soon, because it is impossible to identify an actual user of this link. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-09-28[Bluetooth] Support create connection cancel commandMarcel Holtmann
In case of non-blocking connects it is possible that the last user of an ACL link quits before the connection has been fully established. This will lead to a race condition where the internal state of a connection is closed, but the actual link has been established and is active. In case of Bluetooth 1.2 and later devices it is possible to call create connection cancel to abort the connect. For older devices the disconnect timer will be used to trigger the needed disconnect. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2006-09-28[Bluetooth] Read local version information on device initMarcel Holtmann
The local version information are needed to identify certain feature sets of devices. They must be read on device init and stored for later use. It is also possible to access them through the device model. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

2006-09-28[Bluetooth] Integrate services into the driver modelMarcel Holtmann
This patch integrates the services of the Bluetooth protocols RFCOMM, BNEP and HIDP into the driver model. This makes it possible to assign the virtual TTY, network and input devices to a specific Bluetooth connection. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2006-09-28[Bluetooth] Integrate low-level connections into the driver modelMarcel Holtmann

This patch removes the unused device attribute entries for the Bluetooth host controllers. Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2006-07-24[Bluetooth] Correct RFCOMM channel MTU for broken implementationsMarcel Holtmann
Some Bluetooth RFCOMM implementations try to negotiate a bigger channel MTU than we can support for a particular session. The maximum MTU for a RFCOMM session is limited through the L2CAP layer. So if the other side proposes a channel MTU that is bigger than the underlying L2CAP MTU, we should reduce it to the L2CAP MTU of the session minus five bytes for the RFCOMM headers.

2006-07-12[Bluetooth] Fix deadlock in the L2CAP layerMarcel Holtmann
The Bluetooth L2CAP layer has 2 locks that are used in softirq context, (one spinlock and one rwlock, where the softirq usage is readlock) but where not all usages of the lock were _bh safe.

2006-07-12[Bluetooth] Let BT_HIDP depend on INPUTMarcel Holtmann
This patch lets BT_HIDP depend on instead of select INPUT. This fixes the following warning during an s390 build: net/bluetooth/hidp/Kconfig:4:warning: 'select' used by config symbol 'BT_HIDP' refer to undefined symbol 'INPUT' A dependency on INPUT also implies !S390 (and therefore makes the explicit dependency obsolete) since INPUT is not available on s390. The practical difference should be nearly zero, since INPUT is always set to y unless EMBEDDED=y (or S390=y).

2006-07-03[Bluetooth] Allow disabling of credit based flow controlMarcel Holtmann
This patch adds the module parameter disable_cfc which can be used to disable the credit based flow control. The credit based flow control was introduced with the Bluetooth 1.1 specification and devices can negotiate its support, but for testing purpose it is helpful to allow disabling of it.
