      xfrm: Fix kernel panic when flush and dump SPD entries · d5654efd
      由 Wei Yongjun 提交于 
      After flush the SPD entries, dump the SPD entries will cause kernel painc.

Used the following commands to reproduct:

- echo 'spdflush;' | setkey -c
- echo 'spdadd 3ffe:501:ffff:ff01::/64 3ffe:501:ffff:ff04::/64  any -P out ipsec \
  ah/tunnel/3ffe:501:ffff:ff00:200:ff:fe00:b0b0-3ffe:501:ffff:ff02:200:ff:fe00:a1a1/require;\
  spddump;' | setkey -c
- echo 'spdflush; spddump;' | setkey -c
- echo 'spdadd 3ffe:501:ffff:ff01::/64 3ffe:501:ffff:ff04::/64  any -P out ipsec \
  ah/tunnel/3ffe:501:ffff:ff00:200:ff:fe00:b0b0-3ffe:501:ffff:ff02:200:ff:fe00:a1a1/require;\
  spddump;' | setkey -c

This is because when flush the SPD entries, the SPD entry is not remove
from the list.

This patch fix the problem by remove the SPD entry from the list.

      Bluetooth: Fix RFCOMM release oops when device is still in use · 9a5df923
      由 Marcel Holtmann 提交于 
      It turns out that the following sequence of actions will reproduce the
oops:

  1. Create a new RFCOMM device (using RFCOMMCREATEDEV ioctl)
  2. (Try to) open the device
  3. Release the RFCOMM device (using RFCOMMRELEASEDEV ioctl)

At this point, the "/dev/rfcomm*" device is still in use, but it is gone
from the internal list, so the device id can be reused.

  4. Create a new RFCOMM device with the same device id as before

And now kobject will complain that the TTY already exists.

(See http://lkml.org/lkml/2008/7/13/89 for a reproducible test-case.)

This patch attempts to correct this by only removing the device from the
internal list of devices at the final unregister stage, so that the id
won't get reused until the device has been completely destructed.

This should be safe as the RFCOMM_TTY_RELEASED bit will be set for the
device and prevent the device from being reopened after it has been
released.

      Bluetooth: Fix format arguments warning · 2e792995
      由 Marcel Holtmann 提交于 
      Newer GCC versions are a little bit picky about how to deal with format
arguments:

net/bluetooth/hci_sysfs.c: In function ‘hci_register_sysfs’:
net/bluetooth/hci_sysfs.c:418: warning: format not a string literal and no format arguments

It is simple enough to fix and makes the compiler happy.

      Bluetooth: Enable per-module dynamic debug messages · a418b893
      由 Marcel Holtmann 提交于 
      With the introduction of CONFIG_DYNAMIC_PRINTK_DEBUG it is possible to
allow debugging without having to recompile the kernel. This patch turns
all BT_DBG() calls into pr_debug() to support dynamic debug messages.

As a side effect all CONFIG_BT_*_DEBUG statements are now removed and
some broken debug entries have been fixed.

      Bluetooth: Send HCI Reset command by default on device initialization · 7a9d4020
      由 Marcel Holtmann 提交于 
      The Bluetooth subsystem was not using the HCI Reset command when doing
device initialization. The Bluetooth 1.0b specification was ambiguous
on how the device firmware was suppose to handle it. Almost every device
was triggering a transport reset at the same time. In case of USB this
ended up in disconnects from the bus.

All modern Bluetooth dongles handle this perfectly fine and a lot of
them actually require that HCI Reset is sent. If not then they are
either stuck in their HID Proxy mode or their internal structures for
inquiry and paging are not correctly setup.

To handle old and new devices smoothly the Bluetooth subsystem contains
a quirk to force the HCI Reset on initialization. However maintaining
such a quirk becomes more and more complicated. This patch turns the
logic around and lets the old devices disable the HCI Reset command.

The only device where the HCI_QUIRK_NO_RESET is still needed are the
original Digianswer devices and dongles with an early CSR firmware.

CSR reported that they fixed this for version 12 firmware. The last
official release of version 11 firmware is build ID 115. The first
version 12 candidate was build ID 117.

      Bluetooth: Fix warnings for bt_key_strings and bt_slock_key_strings · db7aa1c2
      由 Marcel Holtmann 提交于 
      After adding proper lockdep annotations for Bluetooth protocols the case
when lockdep is disabled produced two compiler warnings:

net/bluetooth/af_bluetooth.c:60: warning: ‘bt_key_strings’ defined but not used
net/bluetooth/af_bluetooth.c:71: warning: ‘bt_slock_key_strings’ defined but not used

Fix both of them by adding a CONFIG_DEBUG_LOCK_ALLOC conditional around
them and re-arranging the code a little bit.

      Bluetooth: Fix leak of uninitialized data to userspace · c6bf514c
      由 Vegard Nossum 提交于 
          struct hci_dev_list_req {
            __u16  dev_num;
            struct hci_dev_req dev_req[0];  /* hci_dev_req structures */
    };

sizeof(struct hci_dev_list_req) == 4, so the two bytes immediately
following "dev_num" will never be initialized. When this structure
is copied to userspace, these uninitialized bytes are leaked.

Fix by using kzalloc() instead of kmalloc(). Found using kmemcheck.
