2021-08-29mwifiex: pcie: add reset_d3cold quirk for Surface gen4+ devicesTsuchiya Yuto
To reset mwifiex on Surface gen4+ (Pro 4 or later gen) devices, it seems that putting the wifi device into D3cold is required according to errata.inf file on Windows installation (Windows/INF/errata.inf). This patch adds a function that performs power-cycle (put into D3cold then D0) and call the function at the end of reset_prepare(). Note: Need to also reset the parent device (bridge) of wifi on SB1; it might be because the bridge of wifi always reports it's in D3hot. When I tried to reset only the wifi device (not touching parent), it gave the following error and the reset failed: acpi device:4b: Cannot transition to power state D0 for parent in D3hot mwifiex_pcie 0000:03:00.0: can't change power state from D3cold to D0 (config space inaccessible) Signed-off-by: Tsuchiya Yuto <kitakar@gmail.com> Signed-off-by: Jonas Dreßler <verdre@v0yd.nl> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> Link: https://lore.kernel.org/r/20210820142050.35741-3-verdre@v0yd.nl

2021-08-29brcmfmac: pcie: fix oops on failure to resume and reprobeAhmad Fatoum
When resuming from suspend, brcmf_pcie_pm_leave_D3 will first attempt a hot resume and then fall back to removing the PCI device and then reprobing. If this probe fails, the kernel will oops, because brcmf_err, which is called to report the failure will dereference the stale bus pointer. Open code and use the default bus-less brcmf_err to avoid this.

2021-08-29bcma: Fix memory leak for internally-handled coresZenghui Yu
kmemleak reported that dev_name() of internally-handled cores were leaked on driver unbinding. Let's use device_initialize() to take refcounts for them and put_device() to properly free the related stuff. While looking at it, there's another potential issue for those which should be *registered* into driver core. If device_register() failed, we put device once and freed bcma_device structures. In bcma_unregister_cores(), they're treated as unregistered and we hit both UAF and double-free. That smells not good and has also been fixed now.

This error path is unlikely because of it checked for NULL and returned -ENOMEM earlier in the function. But it should return an error code here as well if we ever do hit it because of a race condition or something.

2021-08-29ath9k: fix sleeping in atomic contextMiaoqing Pan
The problem is that gpio_free() can sleep and the cfg_soc() can be called with spinlocks held. One problematic call tree is: --> ath_reset_internal() takes &sc->sc_pcu_lock spin lock --> ath9k_hw_reset() --> ath9k_hw_gpio_request_in() --> ath9k_hw_gpio_request() --> ath9k_hw_gpio_cfg_soc() Remove gpio_free(), use error message instead, so we should make sure there is no GPIO conflict. Also remove ath9k_hw_gpio_free() from ath9k_hw_apply_gpio_override(), as gpio_mask will never be set for SOC chips.

2021-08-29ath9k: fix OOB read ar9300_eeprom_restore_internalZekun Shen
Bad header can have large length field which can cause OOB. cptr is the last bytes for read, and the eeprom is parsed from high to low address. The OOB, triggered by the condition length > cptr could cause memory error with a read on negative index. There are some sanity check around length, but it is not compared with cptr (the remaining bytes). Here, the corrupted/bad EEPROM can cause panic. I was able to reproduce the crash, but I cannot find the log and the reproducer now. After I applied the patch, the bug is no longer reproducible.

2021-08-29wcn36xx: Fix missing frame timestamp for beacon/probe-respLoic Poulain
When receiving a beacon or probe response, we should update the boottime_ns field which is the timestamp the frame was received at. (cf mac80211.h) This fixes a scanning issue with Android since it relies on this timestamp to determine when the AP has been seen for the last time (via the nl80211 BSS_LAST_SEEN_BOOTTIME parameter).

2021-08-29wcn36xx: Allow firmware name to be overridden by DTBjorn Andersson
The WLAN NV firmware blob differs between platforms, and possibly devices, so add support in the wcn36xx driver for reading the path of this file from DT in order to allow these files to live in a generic file system (or linux-firmware). For some reason the parent (wcnss_ctrl) also needs to upload this blob, so rather than specifying the same information in both nodes wcn36xx reads the string from the parent's of_node.

If the operating channel is the first in the scan list, it was seen that a finish scan request would be sent before a start scan request was sent, causing the firmware to fail all future scans.

2021-08-29habanalabs: add wait-for-multi-CS uAPIOhad Sharabi
When user sends multiple CSs, waiting for each CS is not efficient as it involves many user-kernel context switches. In order to address this issue we add support to "wait on multiple CSs" using a new uAPI which can wait on maximum of 32 CSs. The new uAPI is defined using a new flag - WAIT_FOR_MULTI_CS - in the wait_for_cs IOCTL. The input parameters for this uAPI will be: @seq: user pointer to an array of up to 32 CS's sequence numbers. @seq_array_len: length of sequence array. @timeout_us: timeout for waiting for any CS. The output paramateres for this API will be: @status: multi CS ioctl completion status (dedicated status was added as well). @flags: bitmap of output flags of the CS. @cs_completion_map: bitmap for multi CS, if CS sequence that was placed in index N in input seq array has completed- the N-th bit in cs_completion_map will be 1, otherwise it will be 0. @timestamp_nsec: timestamp of the first completed CS Signed-off-by: Ohad Sharabi <osharabi@habana.ai> Reviewed-by: Oded Gabbay <ogabbay@kernel.org> Signed-off-by: Oded Gabbay <ogabbay@kernel.org>
