2014-10-25Bluetooth: Remove redundant check on hci_conn's device classAlfonso Acosta1-2/+1
NULL-checking conn->dev_class is pointless since the variable is defined as an array, i.e. it will always be non-NULL. Signed-off-by: Alfonso Acosta <fons@spotify.com> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2014-10-25Bluetooth: Include ADV_IND report in Device Connected eventAlfonso Acosta3-16/+42
There are scenarios when autoconnecting to a device after the reception of an ADV_IND report (action 0x02), in which userland might want to examine the report's contents. For instance, the Service Data might have changed and it would be useful to know ahead of time before starting any GATT procedures. Also, the ADV_IND may contain Manufacturer Specific data which would be lost if not propagated to userland. In fact, this patch results from the need to rebond with a device lacking persistent storage which notifies about losing its LTK in ADV_IND reports. This patch appends the ADV_IND report which triggered the autoconnection to the EIR Data in the Device Connected event.

Sometimes the async state function is call in an context where the spi irq is diabled. This patch fix the handling to enable the irq when spi_async failed in the async state change calling chain. We do this by a context parameter irq_enable and evaluate this parameter when spi_async failed instead of returning spi_async errno.

2014-10-25at86rf230: fix race conditionAlexander Aring1-1/+1
When the driver waits for a tx completion currently the driver direct enables the irq. When we switching to RX_AACK_ON some steps afterwards the driver could receive a new frame and request resources which are already in use, for example irq state change resource. To be sure there are no new interrupts when we switching to RX_AACK_ON, we enable the irq when state change to RX_AACK_ON was completed.

2014-10-23iwlwifi: dvm: drop non VO frames when flushingEmmanuel Grumbach1-11/+13
When mac80211 wants to ensure that a frame is sent, it calls the flush() callback. Until now, iwldvm implemented this by waiting that all the frames are sent (ACKed or timeout). In case of weak signal, this can take a significant amount of time, delaying the next connection (in case of roaming). Many users have reported that the flush would take too long leading to the following error messages to be printed: iwlwifi 0000:03:00.0: fail to flush all tx fifo queues Q 2 iwlwifi 0000:03:00.0: Current SW read_ptr 161 write_ptr 201 iwl data: 00000000: 00 00 00 00 00 00 00 00 fe ff 01 00 00 00 00 00 [snip] iwlwifi 0000:03:00.0: FH TRBs(0) = 0x00000000 [snip] iwlwifi 0000:03:00.0: Q 0 is active and mapped to fifo 3 ra_tid 0x0000 [9,9] [snip] Instead of waiting for these packets, simply drop them. This significantly improves the responsiveness of the network. Note that all the queues are flushed, but the VO one. This is not typically used by the applications and it likely contains management frames that are useful for connection or roaming. This bug is tracked here: https://bugzilla.kernel.org/show_bug.cgi?id=56581 But it is duplicated in distributions' trackers.

2014-10-21ath10k: retrieve calibration data from fileKalle Valo4-13/+102
A frequent request have been to be able to provide calibration data from a file as some of the AP devices store the calibration data on an MTD partition. This patchset adds support for that and also makes it easier to add Device Tree support later on. The calibration data is found by using the id string provided by dev_name() using this format: cal-<bus>-<id>.bin With PCI the id string contains bus, slot and func values. For example for a PCI device in bus 2 slot 0, ath10k will try to retrieve a calibration data from a file: /lib/firmware/ath10k/cal-pci-0000:02:00.0.bin The calibration data sequence is: 1. Check with request_firmware() if there's a calibration file ("cal-<bus>-<id>.bin") on the filesystem for this device. If yes, use that. If not, goto 2 2. Check if otp.bin is able to successfully load the calibration data from OTP. If yes, use that. If not, goto 3. 4. Print an error message that no calibration data found and stop driver initialization for this device. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2014-10-19Net: DSA: Fix checking for get_phy_flags functionAndrew Lunn1-1/+1
The check for the presence or not of the optional switch function get_phy_flags() called the function, rather than checked to see if it is a NULL pointer. This causes a derefernce of a NULL pointer on all switch chips except the sf2, the only switch to implement this call.

2014-10-19sparc64: Do not define thread fpregs save area as zero-length array.David S. Miller1-1/+2
This breaks the stack end corruption detection facility. What that facility does it write a magic value to "end_of_stack()" and checking to see if it gets overwritten. "end_of_stack()" is "task_thread_info(p) + 1", which for sparc64 is the beginning of the FPU register save area. So once the user uses the FPU, the magic value is overwritten and the debug checks trigger. Fix this by making the size explicit. Due to the size we use for the fpsaved[], gsr[], and xfsr[] arrays we are limited to 7 levels of FPU state saves. So each FPU register set is 256 bytes, allocate 256 * 7 for the fpregs area.

2014-10-19sparc64: Fix corrupted thread fault code.David S. Miller2-6/+6
Every path that ends up at do_sparc64_fault() must install a valid FAULT_CODE_* bitmask in the per-thread fault code byte. Two paths leading to the label winfix_trampoline (which expects the FAULT_CODE_* mask in register %g4) were not doing so: 1) For pre-hypervisor TLB protection violation traps, if we took the 'winfix_trampoline' path we wouldn't have %g4 initialized with the FAULT_CODE_* value yet. Resulting in using the TLB_TAG_ACCESS register address value instead. 2) In the TSB miss path, when we notice that we are going to use a hugepage mapping, but we haven't allocated the hugepage TSB yet, we still have to take the window fixup case into consideration and in that particular path we leave %g4 not setup properly. Errors on this sort were largely invisible previously, but after commit 4ccb9272892c33ef1c19a783cfa87103b30c2784 ("sparc64: sun4v TLB error power off events") we now have a fault_code mask bit (FAULT_CODE_BAD_RA) that triggers due to this bug. FAULT_CODE_BAD_RA triggers because this bit is set in TLB_TAG_ACCESS (see #1 above) and thus we get seemingly random bus errors triggered for user processes.
