      "title": "wifi: ath10k: avoid NULL pointer error during sdio remove",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: ath10k: avoid NULL pointer error during sdio remove\n\nWhen running 'rmmod ath10k', ath10k_sdio_remove() will free sdio\nworkqueue by destroy_workqueue(). But if CONFIG_INIT_ON_FREE_DEFAULT_ON\nis set to yes, kernel panic will happen:\nCall trace:\n destroy_workqueue+0x1c/0x258\n ath10k_sdio_remove+0x84/0x94\n sdio_bus_remove+0x50/0x16c\n device_release_driver_internal+0x188/0x25c\n device_driver_detach+0x20/0x2c\n\nThis is because during 'rmmod ath10k', ath10k_sdio_remove() will call\nath10k_core_destroy() before destroy_workqueue(). wiphy_dev_release()\nwill finally be called in ath10k_core_destroy(). This function will free\nstruct cfg80211_registered_device *rdev and all its members, including\nwiphy, dev and the pointer of sdio workqueue. Then the pointer of sdio\nworkqueue will be set to NULL due to CONFIG_INIT_ON_FREE_DEFAULT_ON.\n\nAfter device release, destroy_workqueue() will use NULL pointer then the\nkernel panic happen.\n\nCall trace:\nath10k_sdio_remove\n  ->ath10k_core_unregister\n    ……\n    ->ath10k_core_stop\n      ->ath10k_hif_stop\n        ->ath10k_sdio_irq_disable\n    ->ath10k_hif_power_down\n      ->del_timer_sync(&ar_sdio->sleep_timer)\n  ->ath10k_core_destroy\n    ->ath10k_mac_destroy\n      ->ieee80211_free_hw\n        ->wiphy_free\n    ……\n          ->wiphy_dev_release\n  ->destroy_workqueue\n\nNeed to call destroy_workqueue() before ath10k_core_destroy(), free\nthe work queue buffer first and then free pointer of work queue by\nath10k_core_destroy(). This order matches the error path order in\nath10k_sdio_probe().\n\nNo work will be queued on sdio workqueue between it is destroyed and\nath10k_core_destroy() is called. Based on the call_stack above, the\nreason is:\nOnly ath10k_sdio_sleep_timer_handler(), ath10k_sdio_hif_tx_sg() and\nath10k_sdio_irq_disable() will queue work on sdio workqueue.\nSleep timer will be deleted before ath10k_core_destroy() in\nath10k_hif_power_down().\nath10k_sdio_irq_disable() only be called in ath10k_hif_stop().\nath10k_core_unregister() will call ath10k_hif_power_down() to stop hif\nbus, so ath10k_sdio_hif_tx_sg() won't be called anymore.\n\nTested-on: QCA6174 hw3.2 SDIO WLAN.RMH.4.4.1-00189",
