Multipath errors were seen during failback due to login timeout. The remote device sent LOGO, the local host tore down the session and did relogin. The RSCN arrived indicates remote device is going through failover after which the relogin is in a 20s timeout phase. At this point the driver is stuck in the relogin process. Add a fix to delete the session as part of abort/flush the login. Link: https://lore.kernel.org/r/20200806111014.28434-5-njavali@marvell.comReviewed-by:

John Garry reported 'sdebug_q_cmd_complete: scp is NULL' failures that were mainly seen on aarch64 machines (e.g. RPi 4 with four A72 CPUs). The problem was tracked down to a missing critical section on a "short circuit" path. Namely, the time to process the current command so far has already exceeded the requested command duration (i.e. the number of nanoseconds in the ndelay parameter). The random=1 parameter setting was pivotal in finding this error. The failure scenario involved first taking that "short circuit" path (due to a very short command duration) and then taking the more likely hrtimer_start() path (due to a longer command duration). With random=1 each command's duration is taken from the uniformly distributed [0..ndelay) interval. The fio utility also helped by reliably generating the error scenario at about once per minute on a RPi 4 (64 bit OS).

Before v4.15 commit 75492a51 ("s390/scsi: Convert timers to use timer_setup()"), we intentionally only passed zfcp_adapter as context argument to zfcp_fsf_request_timeout_handler(). Since we only trigger adapter recovery, it was unnecessary to sync against races between timeout and (late) completion. Likewise, we only passed zfcp_erp_action as context argument to zfcp_erp_timeout_handler(). Since we only wakeup an ERP action, it was unnecessary to sync against races between timeout and (late) completion. Meanwhile the timeout handlers get timer_list as context argument and do a timer-specific container-of to zfcp_fsf_req which can have been freed. Fix it by making sure that any request timeout handlers, that might just have started before del_timer(), are completed by using del_timer_sync() instead. This ensures the request free happens afterwards. Space time diagram of potential use-after-free: Basic idea is to have 2 or more pending requests whose timeouts run out at almost the same time. req 1 timeout ERP thread req 2 timeout ---------------- ---------------- --------------------------------------- zfcp_fsf_request_timeout_handler fsf_req = from_timer(fsf_req, t, timer) adapter = fsf_req->adapter zfcp_qdio_siosl(adapter) zfcp_erp_adapter_reopen(adapter,...) zfcp_erp_strategy ... zfcp_fsf_req_dismiss_all list_for_each_entry_safe zfcp_fsf_req_complete 1 del_timer 1 zfcp_fsf_req_free 1 zfcp_fsf_req_complete 2 zfcp_fsf_request_timeout_handler del_timer 2 fsf_req = from_timer(fsf_req, t, timer) zfcp_fsf_req_free 2 adapter = fsf_req->adapter ^^^^^^^ already freed Link: https://lore.kernel.org/r/20200813152856.50088-1-maier@linux.ibm.com Fixes: 75492a51 ("s390/scsi: Convert timers to use timer_setup()") Cc: <stable@vger.kernel.org> #4.15+ Suggested-by:

If the bit corresponding to a task in the Doorbell register has been cleared, no need to poll the status of the task on the device side and to send an Abort Task TM. Instead, let it directly goto cleanup. In addition, to keep original debug output, move the goto below the debug print.

Stanley Chu authored
If somehow no interrupt notification is raised for a completed request and its doorbell bit is cleared by host, UFS driver needs to cleanup its outstanding bit in ufshcd_abort(). Otherwise, system may behave abnormally in the following scenario: After ufshcd_abort() returns, this request will be requeued by SCSI layer with its outstanding bit set. Any future completed request will trigger ufshcd_transfer_req_compl() to handle all "completed outstanding bits". At this time the "abnormal outstanding bit" will be detected and the "requeued request" will be chosen to execute request post-processing flow. This is wrong because this request is still "alive".

Stanley Chu authored
In ufshcd_suspend(), after clk-gating is suspended and link is set as Hibern8 state, ufshcd_hold() is still possibly invoked before ufshcd_suspend() returns. For example, MediaTek's suspend vops may issue UIC commands which would call ufshcd_hold() during the command issuing flow. Now if UFSHCD_CAP_HIBERN8_WITH_CLK_GATING capability is enabled, then ufshcd_hold() may enter infinite loops because there is no clk-ungating work scheduled or pending. In this case, ufshcd_hold() shall just bypass, and keep the link as Hibern8 state. Link: https://lore.kernel.org/r/20200809050734.18740-1-stanley.chu@mediatek.comReviewed-by:

General fixes too, and a lot of them marked for stable. Lastly, a bit of fallout from the async buffered reads, where we now more easily trigger short reads. Some applications don't really like that, so the io_read() code now handles short reads internally, and got a cleanup along the way so that it's now easier to read (and documented).

One case was missed in the short IO retry handling, and that's hitting -EAGAIN on a blocking attempt read (eg from io-wq context). This is a problem on sockets that are marked as non-blocking when created, they don't carry any REQ_F_NOWAIT information to help us terminate them instead of perpetually retrying.

There's a bit of confusion on the matching pairs of poll vs double poll, depending on if the request is a pure poll (IORING_OP_POLL_ADD) or poll driven retry. Add io_poll_get_double() that returns the double poll waitqueue, if any, and io_poll_get_single() that returns the original poll waitqueue. With that, remove the argument to io_poll_remove_double(). Finally ensure that wait->private is cleared once the double poll handler has run, so that remove knows it's already been seen.

The ioreadX() helpers have inconsistent interface. On some architectures void *__iomem address argument is a pointer to const, on some not. Implementations of ioreadX() do not modify the memory under the address so they can be converted to a "const" version for const-safety and consistency among architectures. Signed-off-by:
