2019-12-18rsi_91x_usb: fix interface sanity checkJohan Hovold
Make sure to use the current alternate setting when verifying the interface descriptors to avoid binding to an invalid interface. Failing to do so could cause the driver to misbehave or trigger a WARN() in usb_submit_urb() that kernels with panic_on_warn set would choke on.

2019-12-18rsi: add missing endpoint sanity checksJohan Hovold
The driver expects at least one bulk-in endpoint when in "wifi-alone" operating mode and two bulk-in endpoints otherwise, and would otherwise fail to to submit the corresponding bulk URB to the default pipe during probe with a somewhat cryptic message: rsi_91x: rsi_rx_urb_submit: Failed in urb submission rsi_91x: rsi_probe: Failed in probe...Exiting RSI-USB WLAN: probe of 2-2.4:1.0 failed with error -8 The current endpoint sanity check looks broken and would only bail out early if there was no bulk-in endpoint but at least one bulk-out endpoint. Tighten this check to always require at least one bulk-in and one bulk-out endpoint, and add the missing sanity check for a Bluetooth bulk-in endpoint when in a BT operating mode. Also make sure to log an informative error message when the expected endpoints are missing. Signed-off-by: Johan Hovold <johan@kernel.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2019-10-04mac80211: simplify TX aggregation startJohannes Berg
There really is no need to make drivers call the ieee80211_start_tx_ba_cb_irqsafe() function and then schedule the worker if all we want is to set a bit. Add a new return value (that was previously considered invalid) to indicate that the driver is immediately ready for the session, and make drivers use it. The only drivers that remain different are the Intel ones as they need to negotiate more with the firmware.

2019-09-03rsi: fix a double free bug in rsi_91x_deinit()Hui Peng
`dev` (struct rsi_91x_usbdev *) field of adapter (struct rsi_91x_usbdev *) is allocated and initialized in `rsi_init_usb_interface`. If any error is detected in information read from the device side, `rsi_init_usb_interface` will be freed. However, in the higher level error handling code in `rsi_probe`, if error is detected, `rsi_91x_deinit` is called again, in which `dev` will be freed again, resulting double free. This patch fixes the double free by removing the free operation on `dev` in `rsi_init_usb_interface`, because `rsi_91x_deinit` is also used in `rsi_disconnect`, in that code path, the `dev` field is not (and thus needs to be) freed. This bug was found in v4.19, but is also present in the latest version of kernel. Fixes CVE-2019-15504.

2019-04-25rsi: miscallaneous changes for 9116 and commonSiva Rebbagondla
Below changes are done: * Device 80MHz clock should be disabled for 9116 in 20MHz band. * Default edca parameters should be used initially before connection. * Default TA aggregation is 3 for 9116. * Bootup parameters should be loaded first when channel is changed. * 4 byte register writes are possible for 9116.

2019-04-25rsi: send new tx command frame wlan9116 featuresSiva Rebbagondla
For 9116 device, we have introduced w9116 features frame, which shall be send when radio capabilities confirm is received. Signed-off-by: Siva Rebbagondla <siva8118@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2019-04-25rsi: new bootup parameters for 9116Siva Rebbagondla
Bootup parameters are different for 9116 device. Check added for device model where-ever bootup parameters are being send. Signed-off-by: Siva Rebbagondla <siva8118@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2019-04-25rsi: change in device init frame sequence for 9116Siva Rebbagondla
Initial frame exchange sequence has been changed for 9116 chip. Getting MAC address using EEPROM read frame will be once common device configuration is done and RESET_MAC frame is sending after bootup parameters confirmation is received, which are different from RS9113 device Signed-off-by: Siva Rebbagondla <siva8118@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2019-04-25rsi: move common part of firmware load to separate functionSiva Rebbagondla
Till software bootloader ready state, communication with device is common for 9113 and 9116. Hence moved that part of firmware loading to separate function rsi_prepare_fw_load(). Also LMAC_VER_OFFSET is different for 9113 and 9116, so renamed existing macro to LMAC_VER_OFFSET_9113 Signed-off-by: Siva Rebbagondla <siva8118@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2019-04-25rsi: add new device model for 9116Siva Rebbagondla
9116 device id entry is added in both SDIO and USB interfaces. New enumberation value taken for the device model. Based on the device model detected run time, few device specific operations needs to be performed. adding rsi_dev_model to get device type in run time, as we can use same driver for 9113 and 9116 except few firmware load changes.

2019-04-25rsi: Fix NULL pointer dereference in kmallocAditya Pakki
kmalloc can fail in rsi_register_rates_channels but memcpy still attempts to write to channels. The patch replaces these calls with kmemdup and passes the error upstream. Signed-off-by: Aditya Pakki <pakki001@umn.edu> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2019-02-28rsi: fix missing null pointer check from a failed ieee80211_probereq_get callColin Ian King
The call to ieee80211_probereq_get can return NULL if a skb allocation fails, so add a null pointer check and free an earlier skb on the error exit return path.

2019-02-08rsi: fix for wowlan wakeup failureSiva Rebbagondla
During wowlan regression tests, sometimes radio is not waking up for wowlan packet in coex mode. This is because of power save is enabled by default in case of coex mode greater than one. Hence, disable power save in coex mode to avoid radio loss. Signed-off-by: Siva Rebbagondla <siva.rebbagondla@redpinesignals.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2019-02-08rsi: resolve power save issue after S4 resumeSiva Rebbagondla
We are redownloading the firmware after S4 restore and observed in stress test that mac80211 sometimes gives power save request after resume which causes the firmware in bad state. mac_ops_resumed flag is added to skip that request until initialisation is done and Keeping power save state is NONE.

2019-02-08rsi: fix wowlan wakeup issue for hibernate(S4)Siva Rebbagondla

2019-02-08rsi: add hci detach for hibernation and poweroffSiva Rebbagondla
As we missed to detach HCI, while entering power off or hibernation, an extra hci interface gets created whenever system is woken up, to avoid this we added hci_detach() in rsi_disconnect(), rsi_freeze(), and rsi_shutdown() functions which are invoked for these tests.
