Most files that have TABs only contain a handful of them.

Outside those, after this patch the following files still contain both 8-space and TAB sequences at the beginning of the line.

2019-01-11scsi: esp: Defer command completion until previous interrupts have been handledGuenter Roeck3-9/+29
The guest OS reads RSTAT, RSEQ, and RINTR, and expects those registers to reflect a consistent state. However, it is possible that the registers can change after RSTAT was read, but before RINTR is read, when esp_command_complete() is called. Guest OS qemu -------- ---- [handle interrupt] Read RSTAT esp_command_complete() RSTAT = STAT_ST esp_dma_done() RSTAT |= STAT_TC RSEQ = 0 RINTR = INTR_BS Read RSEQ Read RINTR RINTR = 0 RSTAT &= ~STAT_TC RSEQ = SEQ_CD The guest OS would then try to handle INTR_BS combined with an old value of RSTAT. This sometimes resulted in lost events, spurious interrupts, guest OS confusion, and stalled SCSI operations. A typical guest error log (observed with various versions of Linux) looks as follows. scsi host1: Spurious irq, sreg=13. ... scsi host1: Aborting command [84531f10:2a] scsi host1: Current command [f882eea8:35] scsi host1: Queued command [84531f10:2a] scsi host1: Active command [f882eea8:35] scsi host1: Dumping command log scsi host1: ent[15] CMD val[44] sreg[90] seqreg[00] sreg2[00] ireg[20] ss[00] event[0c] scsi host1: ent[16] CMD val[01] sreg[90] seqreg[00] sreg2[00] ireg[20] ss[02] event[0c] scsi host1: ent[17] CMD val[43] sreg[90] seqreg[00] sreg2[00] ireg[20] ss[02] event[0c] scsi host1: ent[18] EVENT val[0d] sreg[92] seqreg[04] sreg2[00] ireg[18] ss[00] event[0c] ...

2019-01-11esp-pci: Fix status register write erase controlGuenter Roeck1-3/+3
Per AM53C974 datasheet, definition of "SCSI Bus and Control (SBAC)" register: Bit 24 'STATUS' Write Erase Control This bit controls the Write Erase feature on bits 3:1 and bit 6 of the DMA Status Register ((B)+54h). When this bit is programmed to '1', the state of bits 3:1 are preserved when read. Bits 3:1 are only cleared when a '1' is written to the corresponding bit location. For example, to clear bit 1, the value of '0000_0010b' should be written to the register. When the DMA Status Preserve bit is '0', bits 3:1 are cleared when read. The status register is currently defined to bit 12, not bit 24. Also, its implementation is reversed: The status is auto-cleared if the bit is set to 1, and must be cleared explicitly when the bit is set to 0. This results in spurious interrupts reported by the Linux kernel, and in some cases even results in stalled SCSI operations. Set SBAC_STATUS to bit 24 and reverse the logic to fix the problem.

2018-11-27lsi: Reselection needed to remove pending commands from queueGeorge Kennedy1-12/+36
Under heavy IO (e.g. fio) the queue is not checked frequently enough for pending commands. As a result some pending commands are timed out by the linux sym53c8xx driver, which sends SCSI Abort messages for the timed out commands. The SCSI Abort messages result in linux errors, which show up on the console and in /var/log/messages. e.g. sd 0:0:3:0: [sdd] tag#33 ABORT operation started scsi target0:0:3: control msgout: 80 20 47 d sd 0:0:3:0: ABORT operation complete. scsi target0:0:4: message d sent on bad reselection Now following a WAIT DISCONNECT Script instruction, and if there is no current command, check for a pending command on the queue and if one exists call lsi_reselect().

2018-10-19call HotplugHandler->plug() as the last step in device realizationIgor Mammedov1-10/+1
When [2] was fixed it was agreed that adding and calling post_plug() callback after device_reset() was low risk approach to hotfix issue right before release. So it was merged instead of moving already existing plug() callback after device_reset() is called which would be more risky and require all plug() callbacks audit. Looking at the current plug() callbacks, it doesn't seem that moving plug() callback after device_reset() is breaking anything, so here goes agreed upon [3] proper fix which essentially reverts [1][2] and moves plug() callback after device_reset(). This way devices always comes to plug() stage, after it's been fully initialized (including being reset), which fixes race condition [2] without need for an extra post_plug() callback. 1.

Taking the address of a field in a packed struct is a bad idea, because it might not be actually aligned enough for that pointer type (and thus cause a crash on dereference on some host architectures).

2018-07-16virtio-scsi: fix hotplug ->reset() vs event raceStefan Hajnoczi1-1/+10
There is a race condition during hotplug when iothread is used. It occurs because virtio-scsi may be processing command queues in the iothread while the monitor performs SCSI device hotplug. When a SCSI device is hotplugged the HotplugHandler->plug() callback is invoked and virtio-scsi emits a rescan event to the guest. If the guest submits a SCSI command at this point then it may be cancelled before hotplug completes. This happens because ->reset() is called by hw/core/qdev.c:device_set_realized() after HotplugHandler->plug() has been called and hw/scsi/scsi-disk.c:scsi_disk_reset() purges all requests. This patch uses the new HotplugHandler->post_plug() callback to emit the rescan event after ->reset(). This eliminates the race conditions where requests could be cancelled.

2018-06-29hw/scsi: add VPD Block Limits emulationDaniel Henrique Barboza2-11/+123
The VPD Block Limits Inquiry page is optional, allowing SCSI devices to not implement it. This is the case for devices like the MegaRAID SAS 9361-8i and Microsemi PM8069. In case of SCSI passthrough, the response of this request is used by the QEMU SCSI layer to set the max_io_sectors that the guest device will support, based on the value of the max_sectors_kb that the device has set in the host at that time. Without this response, the guest kernel is free to assume any value of max_io_sectors for the SCSI device. If this value is greater than the value from the host, SCSI Sense errors will occur because the guest will send read/write requests that are larger than the underlying host device is configured to support. An example of this behavior can be seen in [1]. A workaround is to set the max_sectors_kb host value back in the guest kernel (a process that can be automated using rc.local startup scripts and the like), but this has several drawbacks: - it can be troublesome if the guest has many passthrough devices that needs this tuning; - if a change in max_sectors_kb is made in the host side, manual change in the guests will also be required; - during an OS install it is difficult, and sometimes not possible, to go to a terminal and change the max_sectors_kb prior to the installation. This means that the disk can't be used during the install process. The easiest alternative here is to roll back to scsi-hd, install the guest and then go back to SCSI passthrough when the installation is done and max_sectors_kb can be set. An easier way would be to QEMU handle the absence of the Block Limits VPD device response, setting max_io_sectors accordingly and allowing the guest to use the device without the hassle. This patch adds emulation of the Block Limits VPD response for SCSI passthrough devices of type TYPE_DISK that doesn't support it. The following changes were made: - scsi_handle_inquiry_reply will now check the available VPD pages from the Inquiry EVPD reply. In case the device does not - a new function called scsi_generic_set_vpd_bl_emulation, that is called during device realize, was created to set a new flag 'needs_vpd_bl_emulation' of the device. This function retrieves the Inquiry EVPD response of the device to check for VPD BL support. - scsi_handle_inquiry_reply will now check the available VPD pages from the Inquiry EVPD reply in case the device needs VPD BL emulation, adding the Block Limits page (0xb0) to the list. This will make the guest kernel aware of the support that we're now providing by emulation. - a new function scsi_emulate_block_limits creates the emulated Block Limits response. This function is called inside scsi_read_complete in case the device requires Block Limits VPD emulation and we detected a SCSI Sense error in the VPD Block Limits reply that was issued from the guest kernel to the device. This error is expected: we're reporting support from our side, but the device isn't aware of it. With this patch, the guest now queries the Block Limits page during the device configuration because it is being advertised in the Supported Pages response. It will either receive the Block Limits page from the hardware, if it supports it, or will receive an emulated response from QEMU. At any rate, the guest now has the information to set the max_sectors_kb parameter accordingly, sparing the user of SCSI sense errors that would happen without the emulated response and in the absence of Block Limits support from the hardware.

2018-06-29hw/scsi: centralize SG_IO calls into single functionDaniel Henrique Barboza2-45/+34
For the VPD Block Limits emulation with SCSI passthrough, we'll issue an Inquiry request with EVPD set to retrieve the available VPD pages of the device. This would be done in a way similar of what scsi_generic_read_device_identification does: create a SCSI command and a reply buffer, fill in the sg_io_hdr_t structure, call blk_ioctl, check if an error occurred, process the response. This same process is done in other 2 functions, get_device_type and get_stream_blocksize. They differ in the command/reply buffer and post-processing, everything else is almost a copy/paste. Instead of adding a forth copy/pasted-ish code when adding the passthrough VPD BL emulation, this patch extirpates this repetition of those 3 functions and put it into a new one called scsi_SG_IO_FROM_DEV. Any future code that wants to execute an SG_DXFER_FROM_DEV to the device can use it, avoiding filling sg_io_hdr_t again and et cetera.

2018-06-29hw/scsi: cleanups before VPD BL emulationDaniel Henrique Barboza2-230/+248
To add support for the emulation of Block Limits VPD page for passthrough devices, a few adjustments in the current code base is required to avoid repetition and improve clarity. In scsi-generic.c, detach the Inquiry handling from scsi_read_complete and put it into a new function called scsi_handle_inquiry_reply. This change aims to avoid cluttering of scsi_read_complete when we more logic in the Inquiry response handling is added in the next patches, centralizing the changes in the new function. In scsi-disk.c, take the build of all emulated VPD pages from scsi_disk_emulate_inquiry and make it available to other files into a non-static function called scsi_disk_emulate_vpd_page. Making it public will allow the future VPD BL emulation code for passthrough devices to use it from scsi-generic.c, avoiding copy/pasting this code solely for that purpose. It also has the advantage of providing emulation of all VPD pages in case we need to emulate other pages in other scenarios. As a bonus, scsi_disk_emulate_inquiry got tidier.
