* Bluetooth: hci_uart: Fix dereferencing of ERR_PTRChan-yeol Park2015-06-173-0/+3
| | | | | | | | | If h4_recv_buf() return ERR_PTR instead sk_buff pointer, it should be cleared once PTR_ERR is completed for the further dereference such as h4_recv(), or h4_close(). Signed-off-by: Chan-yeol Park <chanyeol.park@samsung.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

* at86rf230: fix phy settings while sleepingAlexander Aring2015-06-161-20/+68
| | | | | | | | | | | While in sleep state then we can't access the at86rf2xx registers. This patch checks if the transceiver is in sleep state before sending spi messages via regmap. Regmap is used on every driver ops callback except for receive and xmit handling, but while receive and xmit handling the phy should not be inside the sleep state.

* Bluetooth: btusb: Fix secure send command length alignment on Intel 8260Marcel Holtmann2015-06-091-12/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the command length alignment issue for Intel Bluetooth 8260. The length of parameters in the firmware downloading command must be multiplication of 4. If not, the command must append Intel_NOP command with extra parameters, zeros, at the end, and the firmware file is already included Intel_NOP command for alignment. This patch checks the next command and if the next command is Intel_NOP command, it reads the Intel_NOP command and send them together. For example, if the data from the firmware file looks like this: 8E FC 03 11 22 33 02 FC 03 00 00 00 Previously, btusb sends two commands: 09 FC 06 8E FC 03 11 22 33 09 FC 06 02 FC 03 00 00 00 This won't work because the length of parameters are 6 which violates the 4 byte alignment. This patch will append them together and send as one command: 09 FC 0C 8E FC 03 11 22 33 02 FC 03 00 00 00 Based on previous work from Tedd Ho-Jeong An <tedd.an@intel.com> Reported-by: Tedd Ho-Jeong An <tedd.an@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Tested-by: Tedd Ho-Jeong An <tedd.an@intel.com> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Cc: stable@vger.kernel.org

UART drivers setup is split in 3 parts: - btbcm_initialize() resets the controller and returns the firmware name based on controller revision and sub_version. - btbtcm_patchram() (already existing and public), which takes the firmware name as parameter, requests the firmware and loads it to the controller. - btbcm_finalize() which resets the controller, reads local version and checks if the controller address is a default one or not.

* net: systemport: rewrite bcm_sysport_rx_refillFlorian Fainelli2015-05-311-40/+41
| | | | | | | | | | | | | | | | | | | | | | | Currently, bcm_sysport_desc_rx() calls bcm_sysport_rx_refill() at the end of Rx packet processing loop, after the current Rx packet has already been passed to napi_gro_receive(). However, bcm_sysport_rx_refill() might fail to allocate a new Rx skb, thus leaving a hole on the Rx queue where no valid Rx buffer exists. To eliminate this situation: 1. Rewrite bcm_sysport_rx_refill() to retain the current Rx skb on the Rx queue if a new replacement Rx skb can't be allocated and DMA-mapped. In this case, the data on the current Rx skb is effectively dropped. 2. Modify bcm_sysport_desc_rx() to call bcm_sysport_rx_refill() at the top of Rx packet processing loop, so that the new replacement Rx skb is already in place before the current Rx skb is processed. This is loosely inspired from d6707bec5986 ("net: bcmgenet: rewrite bcmgenet_rx_refill()") Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* net: thunderx: add 64-bit dependencyArnd Bergmann2015-05-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | The thunderx ethernet driver fails to build on architectures that do not have an atomic readq() and writeq() function for 64-bit PCI bus access: drivers/net/ethernet/cavium/thunder/thunder_bgx.c: In function 'bgx_reg_read': include/asm-generic/io.h:195:23: error: implicit declaration of function 'readq' [-Werror=implicit-function-declaration] It seems impossible to get this driver to work on most 32-bit hardware, so it's better to add an explicit dependency, in order to let us keep building 'allmodconfig' kernels on all architectures. As the driver is meant for the internal hardware on an arm64 SoC, this is not a problem for usability. Allowing the build on all 64-bit architectures rather than just CONFIG_ARM64 on the other hand means that we get the benefit of build testing on x86.

* net/mlx4_core: Make sure there are no pending async events when freeing CQMatan Barak2015-05-311-0/+3
| | | | | | | | | | | | | When freeing a CQ, we need to make sure there are no asynchronous events (on the ASYNC EQ) that could relate to this CQ before freeing it. This is done by introducing synchronize_irq.

* net/mlx4_core: Move affinity hints to mlx4_core ownershipIdo Shamay2015-05-314-9/+59
| | | | | | | | | | | | | | | | | | Now that EQs management is in the sole responsibility of mlx4_core, the IRQ affinity hints configuration should be in its hands as well. request_irq is called only once by the first consumer (maybe mlx4_ib), so mlx4_en passes the affinity mask too late. We also need to request vectors according to the cores we want to run on. mlx4_core distribution of IRQs to cores is straight forward, EQ(i)->IRQ will set affinity hint to core i. Consumers need to request EQ vectors, according to their cores considerations (NUMA).

* net/mlx4: Add EQ poolMatan Barak2015-05-3110-255/+335
| | | | | | | | | | | | | | | | | | | | | | | | | | Previously, mlx4_en allocated EQs and used them exclusively. This affected RoCE performance, as applications which are events sensitive were limited to use only the legacy EQs. Change that by introducing an EQ pool. This pool is managed by mlx4_core. EQs are assigned to ports (when there are limited number of EQs, multiple ports could be assigned to the same EQs). An exception to this rule is the ASYNC EQ which handles various events. Legacy EQs are completely removed as all EQs could be shared. When a consumer (mlx4_ib/mlx4_en) requests an EQ, it asks for EQ serving on a specific port. The core driver calculates which EQ should be assigned to that request. Because IRQs are shared between IB and Ethernet modules, their names only include the PCI device BDF address.

* net/mlx4_core: Demote simple multicast and broadcast flow steering rulesMatan Barak2015-05-312-2/+25
| | | | | | | | | | | | In SRIOV, when simple (i.e - Ethernet L2 only) flow steering rules are created, always create them at MLX4_DOMAIN_NIC priority (instead of the real priority the function created them at). This is done in order to let multiple functions add broadcast/multicast rules without affecting other functions, which is necessary for DPDK in SRIOV.

| * Bluetooth: btusb: fix Realtek suspend/resumeDaniel Drake2015-05-251-1/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Realtek btusb devices don't currently work after suspend/resume because the updated firmware is quietly lost - the USB hub doesn't notice any status change upon resume, but some kind of reset has definitely happened as the LMP subversion has reverted to its original value. Set the reset_resume flag to trigger probe and upload the new firmware again. Like the vendor code, I assume this is not needed when the device is selected as a wakeup source and hence will retain power during suspend. On the 2 products I have to hand, when trying this configuration the hardware seems unable to keep the device powered up during suspend. The USB hub then detects a status change on resume and does a reset, so we do not end up in broken state.
