2018-10-05mt76: fix frag length allocation for usbStanislaw Gruszka1-1/+1
This is correct fix for c12128ce44b0 ("mt76: use a per rx queue page fragment cache"). We use wrong length when we allocate segments for MCU transmissions, which require bigger segment size than e->buf_size. Commit 481bb0432414 ("mt76: usb: make rx page_frag_cache access atomic") partially solved the problem or actually mask it by changing mt76u_mcu_init_rx() and mt76u_alloc_queues() sequence, so e->buf_size become non zero any longer, but still not big enough to handle MCU data. Patch fixes memory corruption which can manifest itself as random, not easy to reproduce crashes, during mt76 driver load or unload.

2018-10-05qtnfmac: do not cancel scan in disconnect callbackIgor Mitsyanko1-2/+0
Do not cancel scan in disconnect callback. If there is an active scan, it will be cancelled by firmware, then host driver will be properly notified by event. Cancelling scan in disconnect callback occasionally may lead to the following race issue. Host is able to queue one scan after scan abort in disconnect callback, and another scan after scan abort in event handler. As a result, firmware receives second scan before the first scan completes.

2018-10-05wlcore: Add support for optional wakeirqTony Lindgren3-9/+40
Now with wlcore using PM runtime, we can also add support for Linux generic wakeirq handling for it if configured in the dts file. The wakeirq can be configured as the second interrupt in the dts file with interrupts-extended property where it is the padconf irq of the OOB GPIO pin used for wlcore interrupt. Note that eventually we should also allow configuring wlcore to use the SDIO dat1 IRQ for wake-up, and in that case the the wakeirq should be configured to be the padconf interrupt of the dat1 pin and not the padconf interrupt of the OOB GPIO pin.

2018-10-05brcmfmac: fix full timeout waiting for action frame on-channel txChung-Hsien Hsu2-2/+17
The driver sends an action frame down and waits for a completion signal triggered by the received BRCMF_E_ACTION_FRAME_OFF_CHAN_COMPLETE event to continue the process. However, the action frame could be transmitted either on the current channel or on an off channel. For the on-channel case, only BRCMF_E_ACTION_FRAME_COMPLETE event will be received when the frame is transmitted, which make the driver always wait a full timeout duration. This patch has the completion signal be triggered by receiving the BRCMF_E_ACTION_FRAME_COMPLETE event for the on-channel case. This change fixes WFA p2p certification 5.1.19 failure.

2018-10-02tls: Add support for inplace records encryptionVakul Garg2-18/+74
Presently, for non-zero copy case, separate pages are allocated for storing plaintext and encrypted text of records. These pages are stored in sg_plaintext_data and sg_encrypted_data scatterlists inside record structure. Further, sg_plaintext_data & sg_encrypted_data are passed to cryptoapis for record encryption. Allocating separate pages for plaintext and encrypted text is inefficient from both required memory and performance point of view. This patch adds support of inplace encryption of records. For non-zero copy case, we reuse the pages from sg_encrypted_data scatterlist to copy the application's plaintext data. For the movement of pages from sg_encrypted_data to sg_plaintext_data scatterlists, we introduce a new function move_to_plaintext_sg(). This function add pages into sg_plaintext_data from sg_encrypted_data scatterlists. tls_do_encryption() is modified to pass the same scatterlist as both source and destination into aead_request_set_crypt() if inplace crypto has been enabled. A new ariable 'inplace_crypto' has been introduced in record structure to signify whether the same scatterlist can be used. By default, the inplace_crypto is enabled in get_rec(). If zero-copy is used (i.e. plaintext data is not copied), inplace_crypto is set to '0'.

2018-10-02hv_netvsc: remove ndo_poll_controllerStephen Hemminger1-23/+0
Similar to other patches from ERic. As diagnosed by Song Liu, ndo_poll_controller() can be very dangerous on loaded hosts, since the cpu calling ndo_poll_controller() might steal all NAPI contexts (for all RX/TX queues of the NIC). This capture can last for unlimited amount of time, since one cpu is generally not able to drain all the queues under load. In netvsc driver it uses NAPI for TX completions. The default poll_napi will do this for us now and avoid the capture.

2018-10-02dpaa_eth: Remove useless declarationNathan Chancellor1-2/+0
Clang warns: drivers/net/ethernet/freescale/dpaa/dpaa_eth.c:2734:34: warning: tentative array definition assumed to have one element static const struct of_device_id dpaa_match[]; ^ 1 warning generated. Turns out that since this driver was introduced in commit 9ad1a3749333 ("dpaa_eth: add support for DPAA Ethernet"), this declaration has been unused. Remove it to silence the warning.
