      "title": "ath10k: skip ath10k_halt during suspend for driver state RESTARTING",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nath10k: skip ath10k_halt during suspend for driver state RESTARTING\n\nDouble free crash is observed when FW recovery(caused by wmi\ntimeout/crash) is followed by immediate suspend event. The FW recovery\nis triggered by ath10k_core_restart() which calls driver clean up via\nath10k_halt(). When the suspend event occurs between the FW recovery,\nthe restart worker thread is put into frozen state until suspend completes.\nThe suspend event triggers ath10k_stop() which again triggers ath10k_halt()\nThe double invocation of ath10k_halt() causes ath10k_htt_rx_free() to be\ncalled twice(Note: ath10k_htt_rx_alloc was not called by restart worker\nthread because of its frozen state), causing the crash.\n\nTo fix this, during the suspend flow, skip call to ath10k_halt() in\nath10k_stop() when the current driver state is ATH10K_STATE_RESTARTING.\nAlso, for driver state ATH10K_STATE_RESTARTING, call\nath10k_wait_for_suspend() in ath10k_stop(). This is because call to\nath10k_wait_for_suspend() is skipped later in\n[ath10k_halt() > ath10k_core_stop()] for the driver state\nATH10K_STATE_RESTARTING.\n\nThe frozen restart worker thread will be cancelled during resume when the\ndevice comes out of suspend.\n\nBelow is the crash stack for reference:\n\n[  428.469167] ------------[ cut here ]------------\n[  428.469180] kernel BUG at mm/slub.c:4150!\n[  428.469193] invalid opcode: 0000 [#1] PREEMPT SMP NOPTI\n[  428.469219] Workqueue: events_unbound async_run_entry_fn\n[  428.469230] RIP: 0010:kfree+0x319/0x31b\n[  428.469241] RSP: 0018:ffffa1fac015fc30 EFLAGS: 00010246\n[  428.469247] RAX: ffffedb10419d108 RBX: ffff8c05262b0000\n[  428.469252] RDX: ffff8c04a8c07000 RSI: 0000000000000000\n[  428.469256] RBP: ffffa1fac015fc78 R08: 0000000000000000\n[  428.469276] CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n[  428.469285] Call Trace:\n[  428.469295]  ? dma_free_attrs+0x5f/0x7d\n[  428.469320]  ath10k_core_stop+0x5b/0x6f\n[  428.469336]  ath10k_halt+0x126/0x177\n[  428.469352]  ath10k_stop+0x41/0x7e\n[  428.469387]  drv_stop+0x88/0x10e\n[  428.469410]  __ieee80211_suspend+0x297/0x411\n[  428.469441]  rdev_suspend+0x6e/0xd0\n[  428.469462]  wiphy_suspend+0xb1/0x105\n[  428.469483]  ? name_show+0x2d/0x2d\n[  428.469490]  dpm_run_callback+0x8c/0x126\n[  428.469511]  ? name_show+0x2d/0x2d\n[  428.469517]  __device_suspend+0x2e7/0x41b\n[  428.469523]  async_suspend+0x1f/0x93\n[  428.469529]  async_run_entry_fn+0x3d/0xd1\n[  428.469535]  process_one_work+0x1b1/0x329\n[  428.469541]  worker_thread+0x213/0x372\n[  428.469547]  kthread+0x150/0x15f\n[  428.469552]  ? pr_cont_work+0x58/0x58\n[  428.469558]  ? kthread_blkcg+0x31/0x31\n\nTested-on: QCA6174 hw3.2 PCI WLAN.RM.4.4.1-00288-QCARMSWPZ-1",
