* Bluetooth: Temporary keys should be retained during connectionVishal Agarwal2012-04-161-0/+1
| | | | | | | | | | If a key is non persistent then it should not be used in future connections but it should be kept for current connection. And it should be removed when connecion is removed.

* Bluetooth: hci_persistent_key should return boolVishal Agarwal2012-04-161-1/+1
| | | | | | | | | | This patch changes the return type of function hci_persistent_key from int to bool because it makes more sense to return information whether a key is persistent or not as a bool.

* Bluetooth: Check for minimum data length in eir_has_data_type()Johan Hedberg2012-03-281-0/+3
| | | | | | | | | | | If passed 0 as data_length the (parsed < data_length - 1) test will be true and cause a buffer overflow. In practice we need at least two bytes for the element length and type so add a test for it to the very beginning of the function.

* Bluetooth: hci_core: fix NULL-pointer dereference at unregisterJohan Hovold2012-03-281-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make sure hci_dev_open returns immediately if hci_dev_unregister has been called. This fixes a race between hci_dev_open and hci_dev_unregister which can lead to a NULL-pointer dereference. Bug is 100% reproducible using hciattach and a disconnected serial port: 0. # hciattach -n /dev/ttyO1 any noflow 1. hci_dev_open called from hci_power_on grabs req lock 2. hci_init_req executes but device fails to initialise (times out eventually) 3. hci_dev_open is called from hci_sock_ioctl and sleeps on req lock 4. hci_uart_tty_close calls hci_dev_unregister and sleeps on req lock in hci_dev_do_close 5. hci_dev_open (1) releases req lock 6. hci_dev_do_close grabs req lock and returns as device is not up 7. hci_dev_unregister sleeps in destroy_workqueue 8. hci_dev_open (3) grabs req lock, calls hci_init_req and eventually sleeps 9. hci_dev_unregister finishes, while hci_dev_open is still running...

| * Yama: add PR_SET_PTRACER_ANYKees Cook2012-02-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | For a process to entirely disable Yama ptrace restrictions, it can use the special PR_SET_PTRACER_ANY pid to indicate that any otherwise allowed process may ptrace it. This is stronger than calling PR_SET_PTRACER with pid "1" because it includes processes in external pid namespaces. This is currently needed by the Chrome renderer, since its crash handler (Breakpad) runs external to the renderer's pid namespace.

This patch fixes this by converting the sequence number from atomic_t to an unsigned int and protect the access with a spin_lock. As a side effect, we get rid of the sequence number wrap handling because the seqence number wraps back to null now without the need to do anything.

There is no standard ror64, so create it. The difference is shift value being "unsigned int" instead of uint64_t (for which there is no reason). gcc starts to emit native ROR instructions which it doesn't do for some reason currently. This should make the code faster. Patch survives in-tree crypto test and ping flood with hmac(sha512) on.

We also added a couple of drivers (but will drop the BQ240022 driver via the arm-soc tree as it's been replaced by the more generic gpio-regulator driver) and Axel Lin continued his relentless and generally awesome stream of fixes and cleanups." * tag 'regulator-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator: (93 commits) regulator: Fix up a confusing dev_warn when DT lookup fails regulator: Convert tps6507x to set_voltage_sel regulator: Refactor tps6507x to use one tps6507x_pmic_ops for all LDOs and DCDCs regulator: Make s5m8767_get_voltage_register always return correct register regulator: s5m8767: Check pdata->buck[2|3|4]_gpiodvs earlier regulator: tps65910: Provide settling time for DCDC voltage change regulator: Add Anatop regulator driver regulator: Simplify implementation of tps65912_get_voltage_dcdc regulator: Use tps65912_set_voltage_sel for both DCDCx and LDOx regulator: tps65910: Provide settling time for enabling rails regulator: max8925: Use DIV_ROUND_UP macro regulator: tps65912: Use simple equations to get register address regulator: Fix the logic of tps65910_get_mode regulator: Merge tps65217_pmic_ldo234_ops and tps65217_pmic_dcdc_ops to tps65217_pmic_ops regulator: Use DIV_ROUND_CLOSEST in wm8350_isink_get_current regulator: Use array to store dcdc_range settings for tps65912 regulator: Rename s5m8767_convert_voltage to s5m8767_convert_voltage_to_sel regulator: tps6524x: Remove unneeded comment for N_REGULATORS regulator: Rename set_voltage_sel callback function name to *_sel regulator: Fix s5m8767_set_voltage_time_sel calculation value ...

| |\ \ \ \ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TWL specific changes, cross-merged with OMAP due to arch/arm wanting to use the new ability to override the voltage set and get operations to support the in-CPU voltage management. The other changes are minor fixes, the addition of a few new regulators and device tree support.

Allow for dynamic mtu configuration through a new, per-port sysfs entry. Since there's a dependency between the port MTU and the max number of HW VLs the port can support, apply a mim/max approach, using a loop that goes down from the highest possible number of VLs to the lowest, using the firmware return status to know whether the requested number of VLs is possible with a given MTU. For now, as with the dynamic link type change / VPI support, the sysfs entry to change the mtu is exposed only when NOT running in SR-IOV mode. To allow changing the MTU for the master in SR-IOV mode, primary-function-initiated FLR (Function Level Reset) needs to be implemented.
