We encountered this in ESX, which relies on these 2 bytes to parse the MISCOMPARE sense code (0xE1, 0x1D, 0x00). Bellow is a simple test to recreate this issue, but during vMotion operations (where VMs are moved from one host to another), this may cause the operation to fail leaving the VM in an inconsistent state. The test I ran to verify that we are indeed missing the bytes is the following: 1. Create a SCST based device 2. Expose the device to 2 ESX hosts 3. Format the device as VMFS5, create a test directory 4. From both hosts, I start writing to this directory (no VMs involved, just write normal files) At this stage, both ESX hosts try to take access to the directory. The VMFS filesystem contains a per-directory lock which is managed by COMPARE AND WRITE command. Each ESX will attempt to change the VMFS lock location from unlocked to locked to create the new file. Obviously there are bound to be failures (which are equivalent to programming locking conflicts), these are reported by the MISCOMPARE sense code. Upon these MISCOMPARE errors, the host will re-try taking the lock until it succeeds, and will then proceed to perform the write operation on the directory. Due to the bug in copying the sense buffer from the SCST core to the QLA ctio, instead of the full sense code, only the key (0xE) is sent, and ESX does not know how to handle it resulting in IO error. Here are the errors as they appear on the command line: /vmfs/volumes/54a297c4-ca5af1cc-7f94-002219d20f28/ats_test # ./open_close_test-esx2.sh ./open_close_test-esx2.sh: line 8: can't create ats_fileoptest-esx2_1.txt: Input/output error ./open_close_test-esx2.sh: line 8: can't create ats_fileoptest-esx2_21.txt: Input/output error ./open_close_test-esx2.sh: line 8: can't create ats_fileoptest-esx2_110.txt: Input/output error ./open_close_test-esx2.sh: line 8: can't create ats_fileoptest-esx2_111.txt: Input/output error In the /var/log/vmkernel.log, we can see that the sense information is missing (0xE, 0x0, 0x0) instead of (0xE, 0x1D, 0x0). 2014-12-30T12:13:20.714Z cpu6:33519)ScsiDeviceIO: 2338: Cmd(0x412e84f957c0) 0x89, CmdSN 0x234d from world 519051 to dev "eui.0024f400d5020007" failed H:0x0 D:0x2 P:0x0 Valid sense data: 0xe 0x0 0x0. 2014-12-30T12:13:20.766Z cpu6:33519)ScsiDeviceIO: 2338: Cmd(0x412e84f91d00) 0x89, CmdSN 0x2350 from world 519051 to dev "eui.0024f400d5020007" failed H:0x0 D:0x2 P:0x0 Valid sense data: 0xe 0x0 0x0. 2014-12-30T12:13:20.766Z cpu6:33519)ScsiDeviceIO: 2338: Cmd(0x412e80449fc0) 0x89, CmdSN 0x234f from world 519051 to dev "eui.0024f400d5020007" failed H:0x0 D:0x2 P:0x0 Valid sense data: 0xe 0x0 0x0.

This patch fixes the following race condition that can occur if SCST_FLAG_SUSPENDED has been set and if scst_init_cmd_list is not empty: * scst_do_job_init() returns to scst_init_thread() and leaves the commands that were on the init list on that list. * scst_init_thread() invokes test_init_cmd_list(). * test_init_cmd_list() returns false because SCST_FLAG_SUSPENDED has been set. * scst_resume_activity() clears SCST_FLAG_SUSPENDED and invokes wake_up_all(&scst_init_cmd_list_waitQ). However, since scst_init_thread() has not yet added the init thread back to scst_init_cmd_list_waitQ this wake_up_all() call doesn't do anything. * scst_init_thread() adds the init thread to scst_init_cmd_list_waitQ and unlocks scst_init_lock. Additionally, remove an unneeded smp_mb__after_clear_bit() call. wake_up_all() guarantees that if it wakes up a thread that that thread sees all store operations that were performed by the thread that invoked wake_up_all() and that preceeded the wake_up_all() invocation.

The warning applies to WRITE SAME commands with LBDATA == PBDATA == 0 (replicate a single block of user data into the specified LBA range). The warning appears to be spurious - when LBDATA == PBDATA == 0, scst_ws_write_cmd_finished() will not use the uninitialized value saved by scst_ws_push_single_write().

In such cases the checks report errors on commands that userland has not yet had an opportunity to parse. NOTE: this includes a refactoring of the EXTRACHECKS to improve clarity.

Under these conditions, most calls to local_irq functions should be replaced by no-ops. The CONFIG_PREEMPT_RT patch defines _nort versions of local_irq functions that compile away under CONFIG_PREEMPT_RT_FULL and compile to their "normal" equivalents otherwise. Define _nort equivalents to support compilation against both "normal" and RT-patched kernels, and use the _nort local_irq functons in cases where spinlocks are taken within a local_irq_save() or local_irq_disable() block.
