2019-10-22ath10k: Fix a NULL-ptr-deref bug in ath10k_usb_alloc_urb_from_pipeHui Peng1-0/+8
The `ar_usb` field of `ath10k_usb_pipe_usb_pipe` objects are initialized to point to the containing `ath10k_usb` object according to endpoint descriptors read from the device side, as shown below in `ath10k_usb_setup_pipe_resources`: for (i = 0; i < iface_desc->desc.bNumEndpoints; ++i) { endpoint = &iface_desc->endpoint[i].desc; // get the address from endpoint descriptor pipe_num = ath10k_usb_get_logical_pipe_num(ar_usb, endpoint->bEndpointAddress, &urbcount); ...... // select the pipe object pipe = &ar_usb->pipes[pipe_num]; // initialize the ar_usb field pipe->ar_usb = ar_usb; } The driver assumes that the addresses reported in endpoint descriptors from device side to be complete. If a device is malicious and does not report complete addresses, it may trigger NULL-ptr-deref `ath10k_usb_alloc_urb_from_pipe` and `ath10k_usb_free_urb_to_pipe`. This patch fixes the bug by preventing potential NULL-ptr-deref.

2019-10-04mac80211: simplify TX aggregation startJohannes Berg4-6/+6
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.

2019-10-02wil6210: check len before memcpy() callsDenis Efremov1-2/+4
memcpy() in wmi_set_ie() and wmi_update_ft_ies() is called with src == NULL and len == 0. This is an undefined behavior. Fix it by checking "ie_len > 0" before the memcpy() calls. As suggested by GCC documentation: "The pointers passed to memmove (and similar functions in <string.h>) must be non-null even when nbytes==0, so GCC can use that information to remove the check after the memmove call."

2019-10-02ath10k: add support for hardware rfkillWen Gong9-1/+178
When hardware rfkill is enabled in the firmware it will report the capability via using WMI_TLV_SYS_CAP_INFO_RFKILL bit in the WMI_SERVICE_READY event to the host. ath10k will check the capability, and if it is enabled then ath10k will set the GPIO information to firmware using WMI_PDEV_SET_PARAM. When the firmware detects hardware rfkill is enabled by the user, it will report it via WMI_RFKILL_STATE_CHANGE_EVENTID. Once ath10k receives the event it will send wmi command WMI_PDEV_SET_PARAM to the firmware to enable/disable the radio and also notifies cfg80211. We can't power off the device when rfkill is enabled, as otherwise the firmware would not be able to detect GPIO changes and report them to the host. So when rfkill is enabled, we need to keep the firmware running. Tested with QCA6174 PCI with firmware WLAN.RM.4.4.1-00109-QCARMSWPZ-1.

This patch restores the old behavior that read the chip_id on the QCA988x before resetting the chip. This needs to be done in this order since the unsupported QCA988x AR1A chips fall off the bus when resetted. Otherwise the next MMIO Op after the reset causes a BUS ERROR and panic.

I think this is because the tx-offchannel logic gets in a loop when ath10k_mac_tx_frm_has_freq(ar) is false, so pkt is never actually sent to the firmware for transmit. This patch fixes the problem on 4.9 for me, and now HS20 clients can work again with my firmware.

2019-10-02net/wireless: Use kmemdup rather than duplicating its implementationFuqian Huang1-4/+2
kmemdup is introduced to duplicate a region of memory in a neat way. Rather than kmalloc/kzalloc + memcpy, which the programmer needs to write the size twice (sometimes lead to mistakes), kmemdup improves readability, leads to smaller code and also reduce the chances of mistakes. Suggestion to use kmemdup rather than using kmalloc/kzalloc + memcpy. Signed-off-by: Fuqian Huang <[email protected]> Signed-off-by: Kalle Valo <[email protected]>

2019-10-01ath10k: switch to ieee80211_tx_dequeue_niErik Stromdahl1-1/+1
Since ath10k_mac_tx_push_txq() can be called from process context, we must explicitly disable softirqs before the call into mac80211. By calling ieee80211_tx_dequeue_ni() instead of ieee80211_tx_dequeue() we make sure softirqs are always disabled even in the case when ath10k_mac_tx_push_txq() is called from process context. Calling ieee80211_tx_dequeue_ni() with softirq's already disabled (e.g., from softirq context) should be safe as the local_bh_disable() and local_bh_enable() functions (called from ieee80211_tx_dequeue_ni) are fully reentrant.

2019-09-23ath10k: Add support to provide higher range mem chunks in wmi init commandSurabhi Vishnoi3-2/+34
With the current implementation of wmi init command, there is no provision for the host driver to provide mem chunks addresses with more than 32-bit, to the firmware. WCN3990 is a 35-bit target and can accept mem chunks addresses which are above 32-bit. If firmware supports address range more than 32 bit, it advertises the support by setting the WMI_SERVICE_EXTEND_ADDRESS service. Based on this service fill the upper bits of paddr while providing the mem chunks in the wmi init command.

2019-09-21ath10k: Add xo calibration support for wifi rf clockGovind Singh3-0/+25
PMIC XO is the clock source for wifi rf clock in integrated wifi chipset ex: WCN3990. Due to board layout errors XO frequency drifts can cause wifi rf clock inaccuracy. XO calibration test tree in Factory Test Mode is used to find the best frequency offset(for example +/-2KHz )by programming XO trim register. This ensure system clock stays within required 20 ppm WLAN rf clock. Retrieve the xo trim offset via system firmware (e.g., device tree), especially in the case where the device doesn't have a useful EEPROM on which to store the calibrated XO offset (e.g., for integrated Wifi). Calibrated XO offset is sent to fw, which compensate the clock drift by programing the XO trim register. Signed-off-by: Govind Singh <[email protected]> Signed-off-by: Kalle Valo <[email protected]>
