Description
In the Linux kernel, the following vulnerability has been resolved:scsi: core: ufs: Fix a hang in the error handlerufshcd_err_handling_prepare() calls ufshcd_rpm_get_sync(). The latterfunction can only succeed if UFSHCD_EH_IN_PROGRESS is not set becauseresuming involves submitting a SCSI command and ufshcd_queuecommand()returns SCSI_MLQUEUE_HOST_BUSY if UFSHCD_EH_IN_PROGRESS is set. Fix thishang by setting UFSHCD_EH_IN_PROGRESS after ufshcd_rpm_get_sync() hasbeen called instead of before.Backtrace:__switch_to+0x174/0x338__schedule+0x600/0x9e4schedule+0x7c/0xe8schedule_timeout+0xa4/0x1c8io_schedule_timeout+0x48/0x70wait_for_common_io+0xa8/0x160 //waiting on START_STOPwait_for_completion_io_timeout+0x10/0x20blk_execute_rq+0xe4/0x1e4scsi_execute_cmd+0x108/0x244ufshcd_set_dev_pwr_mode+0xe8/0x250__ufshcd_wl_resume+0x94/0x354ufshcd_wl_runtime_resume+0x3c/0x174scsi_runtime_resume+0x64/0xa4rpm_resume+0x15c/0xa1c__pm_runtime_resume+0x4c/0x90 // Runtime resume ongoingufshcd_err_handler+0x1a0/0xd08process_one_work+0x174/0x808worker_thread+0x15c/0x490kthread+0xf4/0x1ecret_from_fork+0x10/0x20[ bvanassche: rewrote patch description ]
