* cx82310_eth: wait for firmware to become readyOndrej Zary2015-03-211-6/+24
| | | | | | | | | | | | | | | | | | | When the device is powered up, some (older) firmware versions fail to work properly if we send commands before the boot is complete (everything is OK when the device is hot-plugged). The firmware indicates its ready status by putting the link up. Newer firmwares delay the first command so they don't suffer from this problem. They also report the link being always up. Wait for firmware to become ready (link up) before sending any commands and/or data. This also allows lowering CMD_TIMEOUT value to a reasonable time. Tested with 4.1.0.9 (old) and 4.1.0.30 (new) firmware versions. Signed-off-by: Ondrej Zary <linux@rainbow-software.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* Revert "net: cx82310_eth: use common match macro"Ondrej Zary2015-03-191-1/+10
| | | | | | | | | | | | | | This reverts commit 11ad714b98f6d9ca0067568442afe3e70eb94845 because it breaks cx82310_eth. The custom USB_DEVICE_CLASS macro matches bDeviceClass, bDeviceSubClass and bDeviceProtocol but the common USB_DEVICE_AND_INTERFACE_INFO matches bInterfaceClass, bInterfaceSubClass and bInterfaceProtocol instead, which are not specified.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a capability which let the hw could change the settings automatically when the power change to ON. However, the USB reset would reset the settings to the hw default, so the driver has to restore the relative settings. Otherwise, it would influence the functions of the hw, and the compatibility for the USB hub and USB host controller. The relative settings are as following. - set the power down scale to 96. - enable the power saving function of USB 2.0. - disable the ALDPS of ECM mode. - set burst mode depending on the burst size. - enable the flow control of endpoint full. - set fifo empty boundary to 32448 bytes. - enable the function of exiting LPM when Rx OK occurs. - set the connect timer to 1.

* | hso: fix rx parsing logic when skb allocation failsAleksander Morgado2015-02-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If skb allocation fails once the IP header has been received, the rx state is being set to WAIT_SYNC. The logic, though, shouldn't directly return, as the buffer may contain a full packet, and therefore the WAIT_SYNC state needs to be processed (resetting state to WAIT_IP, clearing rx_buf_size and re-initializing rx_buf_missing). So, just let the while loop continue so that in the next iteration the WAIT_SYNC state cleanly stops the loop. The WAIT_SYNC processing will be done just after that, only if the end of packet is flagged. Signed-off-by: Aleksander Morgado <aleksander@aleksander.es> Signed-off-by: David S.

The table is updated in the probe method and in hso_serial_ref_free() which is called either from the tty cleanup method or from the usb disconnect method. This patch ensures that the serial_table is updated in the disconnect method and no more from the cleanup method to avoid the following potential race condition. - hso_disconnect() is called for usb interface "x". Because the serial port was open and because the cleanup method of the tty_port hasn't been called yet, hso_serial_ref_free() is not run. - hso_probe() is called and fails for a new hso serial usb interface "y". The function hso_free_interface() is called and iterates over the element of serial_table to find the device associated to the usb interface context. If the usb interface context of usb interface "y" has been created at the same place as for usb interface "x", then the cleanup functions are called for usb interfaces "x" and "y" and hso_serial_ref_free() is called for both interfaces. - release_tty() is called for serial port linked to usb interface "x" and possibly crash because the tty_port structure contained in the hso_device structure has been freed.

In the cleanup function, hso_free_interface() calls tty_port_tty_hangup() in view of scheduling a work to hang up the tty if needed. If the port was not open then hso_serial_ref_free() is called directly to cleanup everything. Otherwise, hso_serial_ref_free() is called when the last fd associated to the port is closed. For each open port, tty_release() will call the close method, hso_serial_close(), which drops the last kref and call hso_serial_ref_free() which unregisters, destroys the tty port and finally frees the structure in which the tty_port structure is included. Later, in tty_release(), more precisely when release_tty() is called, the tty_port previously freed is accessed to cancel the tty buf workqueue and it leads to a crash. In view of avoiding this crash, we add a cleanup method that is called at the end of the hangup process and we drop the last kref in this function when all the ports have been closed, when tty_port is no more needed and when it is safe to free the structure containing the tty_port structure.

However, the "byen" could be used to determine which bytes of the 4 bytes to write, so the action could be removed. Signed-off-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: David S.

The patch fixes usb_start_wait_urb() as well. Found by Linux Driver Verification project (linuxtesting.org).

* | qmi_wwan: Set random MAC on devices with buggy fwKristian Evensen2015-01-021-3/+7
|/ | | | | | | | | | | | | | Some buggy firmwares export an incorrect MAC address (00:a0:c6:00:00:00). This makes for example checking devices for random MAC addresses tricky, and you might end up with multiple network interfaces with the same address. This patch tries to fix, or at least improve, the situation by setting the MAC address of devices with this firmware bug to a random address. I tested the patch with two devices that has this firmware bug (Huawei E398 and E392), and network traffic worked fine after changing the address.

| | | | | | | | | | | | Redefine REALTEK_USB_DEVICE for the desired USB interface for probe(). There are three USB interfaces for the device. USB_CLASS_COMM and USB_CLASS_CDC_DATA are for ECM mode (config #2). USB_CLASS_VENDOR_SPEC is for the vendor mode (config #1). However, we are not interesting in USB_CLASS_CDC_DATA for probe(), so redefine REALTEK_USB_DEVICE to ignore the USB interface class of USB_CLASS_CDC_DATA.
