* [BLUETOOTH]: Fix unaligned access in hci_send_to_sock.David S. Miller2006-11-211-4/+7
| | | | | | | | | The "u16 *" derefs of skb->data need to be wrapped inside of a get_unaligned(). Thanks to Gustavo Zacarias for the bug report. Signed-off-by: David S. Miller <davem@davemloft.net>
* [Bluetooth] Ignore L2CAP config requests on disconnectMarcel Holtmann2006-11-211-0/+3
| | | | | | | | | 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>
* [Bluetooth] Always include MTU in L2CAP config responsesMarcel Holtmann2006-11-211-4/+4
| | | | | | | | 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>
* [Bluetooth] Check if RFCOMM session is still attached to the TTYMarcel Holtmann2006-11-211-1/+1

* [Bluetooth] Attach low-level connections to the Bluetooth busMarcel Holtmann2006-11-211-1/+3
| | | | | | | | 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>
* [Bluetooth] Fix HID disconnect NULL pointer dereferenceMarcel Holtmann2006-10-201-4/+2
| | | | | | | | | 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.

* [Bluetooth] Add locking for bt_proto array manipulationMarcel Holtmann2006-10-158-14/+38
| | | | | | | | | | | 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. And in addition all calls to sk_alloc need to be made GFP_ATOMIC now.

* [Bluetooth] Disconnect HID interrupt channel firstMarcel Holtmann2006-10-151-2/+2

* [Bluetooth] Support concurrent connect requestsMarcel Holtmann2006-10-153-7/+16
| | | | | | | | | | | 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.

* [PATCH] const struct tty_operationsJeff Dike2006-10-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | 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.

* [Bluetooth]: Don't update disconnect timer for incoming connectionsMarcel Holtmann2006-09-281-4/+4
| | | | | | | | | | | | 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.

* [Bluetooth] Support create connection cancel commandMarcel Holtmann2006-09-282-4/+31
| | | | | | | | | | | | 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.

* [Bluetooth] Correct RFCOMM channel MTU for broken implementationsMarcel Holtmann2006-07-241-2/+17
| | | | | | | | | | | 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.

* [Bluetooth] Let BT_HIDP depend on INPUTMarcel Holtmann2006-07-121-2/+1
| | | | | | | | | | | | | | | | | 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.

* | [PATCH] remove TTY_DONT_FLIPPaul Fulghum2006-06-281-6/+2
|/ | | | | | | | | | | | | | | | | | | | | Remove TTY_DONT_FLIP tty flag. This flag was introduced in 2.1.X kernels to prevent the N_TTY line discipline functions read_chan() and n_tty_receive_buf() from running at the same time. 2.2.15 introduced tty->read_lock to protect access to the N_TTY read buffer, which is the only state requiring protection between these two functions. The current TTY_DONT_FLIP implementation is broken for SMP, and is not universally honored by drivers that send data directly to the line discipline receive_buf function. Because TTY_DONT_FLIP is not necessary, is broken in implementation, and is not universally honored, it is removed.

* [PATCH] Notifier chain update: API changesAlan Stern2006-03-271-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kernel's implementation of notifier chains is unsafe. There is no protection against entries being added to or removed from a chain while the chain is in use. The issues were discussed in this thread: http://marc.theaimsgroup.com/?l=linux-kernel&m=113018709002036&w=2 We noticed that notifier chains in the kernel fall into two basic usage classes: "Blocking" chains are always called from a process context and the callout routines are allowed to sleep; "Atomic" chains can be called from an atomic context and the callout routines are not allowed to sleep. We decided to codify this distinction and make it part of the API. Therefore this set of patches introduces three new, parallel APIs: one for blocking notifiers, one for atomic notifiers, and one for "raw" notifiers (which is really just the old API under a new name). New kinds of data structures are used for the heads of the chains, and new routines are defined for registration, unregistration, and calling a chain. The three APIs are explained in include/linux/notifier.h and their implementation is in kernel/sys.c. With atomic and blocking chains, the implementation guarantees that the chain links will not be corrupted and that chain callers will not get messed up by entries being added or removed. For raw chains the implementation provides no guarantees at all; users of this API must provide their own protections. (The idea was that situations may come up where the assumptions of the atomic and blocking APIs are not appropriate, so it should be possible for users to handle these things in their own way.) There are some limitations, which should not be too hard to live with. For atomic/blocking chains, registration and unregistration must always be done in a process context since the chain is protected by a mutex/rwsem. Also, a callout routine for a non-raw chain must not try to register or unregister entries on its own chain. (This did happen in a couple of places and the code had to be changed to avoid it.) Since atomic chains may be called from within an NMI handler, they cannot use spinlocks for synchronization. Instead we use RCU. The overhead falls almost entirely in the unregister routine, which is okay since unregistration is much less frequent that calling a chain. Here is the list of chains that we adjusted and their classifications. None of them use the raw API, so for the moment it is only a placeholder. ATOMIC CHAINS ------------- arch/i386/kernel/traps.c: i386die_chain arch/ia64/kernel/traps.c: ia64die_chain arch/powerpc/kernel/traps.c: powerpc_die_chain arch/sparc64/kernel/traps.c: sparc64die_chain arch/x86_64/kernel/traps.c: die_chain drivers/char/ipmi/ipmi_si_intf.c: xaction_notifier_list kernel/panic.c: panic_notifier_list kernel/profile.c: task_free_notifier net/bluetooth/hci_core.c: hci_notifier net/ipv4/netfilter/ip_conntrack_core.c: ip_conntrack_chain net/ipv4/netfilter/ip_conntrack_core.c: ip_conntrack_expect_chain net/ipv6/addrconf.c: inet6addr_chain net/netfilter/nf_conntrack_core.c: nf_conntrack_chain net/netfilter/nf_conntrack_core.c: nf_conntrack_expect_chain net/netlink/af_netlink.c: netlink_chain BLOCKING CHAINS --------------- arch/powerpc/platforms/pseries/reconfig.c: pSeries_reconfig_chain arch/s390/kernel/process.c: idle_chain arch/x86_64/kernel/process.c idle_notifier drivers/base/memory.c: memory_chain drivers/cpufreq/cpufreq.c cpufreq_policy_notifier_list drivers/cpufreq/cpufreq.c cpufreq_transition_notifier_list drivers/macintosh/adb.c: adb_client_list drivers/macintosh/via-pmu.c sleep_notifier_list drivers/macintosh/via-pmu68k.c sleep_notifier_list drivers/macintosh/windfarm_core.c wf_client_list drivers/usb/core/notify.c usb_notifier_list drivers/video/fbmem.c fb_notifier_list kernel/cpu.c cpu_chain kernel/module.c module_notify_list kernel/profile.c munmap_notifier kernel/profile.c task_exit_notifier kernel/sys.c reboot_notifier_list net/core/dev.c netdev_chain net/decnet/dn_dev.c: dnaddr_chain net/ipv4/devinet.c: inetaddr_chain It's possible that some of these classifications are wrong. If they are, please let us know or submit a patch to fix them. Note that any chain that gets called very frequently should be atomic, because the rwsem read-locking used for blocking chains is very likely to incur cache misses on SMP systems. (However, if the chain's callout routines may sleep then the chain cannot be atomic.) The patch set was written by Alan Stern and Chandra Seetharaman, incorporating material written by Keith Owens and suggestions from Paul McKenney and Andrew Morton.

* [PATCH] POLLRDHUP/EPOLLRDHUP handling for half-closed devices notificationsDavide Libenzi2006-03-251-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement the half-closed devices notifiation, by adding a new POLLRDHUP (and its alias EPOLLRDHUP) bit to the existing poll/select sets. Since the existing POLLHUP handling, that does not report correctly half-closed devices, was feared to be changed, this implementation leaves the current POLLHUP reporting unchanged and simply add a new bit that is set in the few places where it makes sense. The same thing was discussed and conceptually agreed quite some time ago: http://lkml.org/lkml/2003/7/12/116 Since this new event bit is added to the existing Linux poll infrastruture, even the existing poll/select system calls will be able to use it. As far as the existing POLLHUP handling, the patch leaves it as is. The pollrdhup-2.6.16.rc5-0.10.diff defines the POLLRDHUP for all the existing archs and sets the bit in the six relevant files. The other attached diff is the simple change required to sys/epoll.h to add the EPOLLRDHUP definition. There is "a stupid program" to test POLLRDHUP delivery here: http://www.xmailserver.org/pollrdhup-test.c It tests poll(2), but since the delivery is same epoll(2) will work equally.
