Rebecca Cran 7b82da70ed MdeModulePkg: Update code to be more C11 compliant by using __func__
__FUNCTION__ is a pre-standard extension that gcc and Visual C++ among
others support, while __func__ was standardized in C99.

Since it's more standard, replace __FUNCTION__ with __func__ throughout
MdeModulePkg.

Yuan Yu d375273c89 MdeModulePkg: ScsiBusDxe: Refactor DiscoverScsiDevice()
Currently DiscoverScsiDevice() returns a boolean which cannot
distinguish a "not found" situation from a real problem like
memory allocation failures.

This patch changes the return value to an EFI_STATUS so that when
memory allocation fails, it will return EFI_OUT_OF_RESOURCES.

Without this change, any FALSE returned by DiscoverScsiDevice()
will result in EFI_OUT_OF_RESOURCES being returned by
ScsiScanCreateDevice(), which will cause a while loop in
SCSIBusDriverBindingStart() to abort before other possible Puns in
the SCSI channel are scanned, which means good devices may not have
a chance to be discovered.  If this good device is the boot device,
boot will fail.

Laszlo Ersek ce13d2d8c8 MdeModulePkg/ScsiBusDxe: don't produce ScsiIo for nonexistent LUNs, part 2
The SPC-4 says about INQUIRY,

> In response to an INQUIRY command received by an incorrect logical unit,
> the SCSI target device shall return the INQUIRY data with the peripheral
> qualifier set to the value defined in 6.4.2. The INQUIRY command shall
> return CHECK CONDITION status only when the device server is unable to
> return the requested INQUIRY data.

When a device server takes the second branch, and returns CHECK CONDITION
for a nonexistent LUN, the InquiryData structure in the
DiscoverScsiDevice() function remains filled with the original zeros.

DiscoverScsiDevice() then sees zero in both Peripheral_Qualifier and
Peripheral_Type, and therefore ScsiBusDxe produces a ScsiIo protocol
instance with device type zero, for the nonexistent LUN.

Device type zero is EFI_SCSI_TYPE_DISK. Thus ScsiDiskDxe binds the bogus
ScsiIo protocol interface, and produces a similarly bogus BlockIo
interface on top. This ripples up to BDS, where UefiBootManagerLib can
auto-generate bogus UEFI boot options for the nonexistent LUNs.

This has been encountered with QEMU, after commit ded6ddc5a7b9 ("scsi:
clarify sense codes for LUN0 emulation", 2017-08-04). QEMU now answers
INQUIRY commands that were directed to nonexistent LUNs with:

> DiscoverScsiDevice:1361: Lun=2 HostAdapterStatus=0 TargetStatus=2
>                          SenseDataLength=18 InquiryDataLength=96
> Sense {
> Sense 000000 70 00 05 00 00 00 00 0A 00 00 00 00 25 00 00 00
> Sense 000010 00 00
> Sense }
> Inquiry {
> Inquiry 000000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
> Inquiry 000010 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
> Inquiry 000020 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
> Inquiry 000030 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
> Inquiry 000040 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
> Inquiry 000050 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
> Inquiry }

The interesting fields are:
- HostAdapterStatus=0 (OK),
- TargetStatus=2 (CHECK CONDITION),
- Sense/Error_Code=0x70 (Current error, Fixed description)
- Sense/Sense_Key=0x05 (ILLEGAL REQUEST)

According to SPC-4 "Table 41 -- Sense key descriptions (part 2 of 2)",
ILLEGAL REQUEST is justified when "the command was addressed to an
incorrect logical unit number".

Thus, recognize this kind of answer for nonexistent LUNs.

(

Checking the status fields and the sense data is justified anyway,
according to the documentation of ScsiInquiryCommand():

>   @retval EFI_SUCCESS                    The command was executed
>                                          successfully. See

Laszlo Ersek 897efb977f MdeModulePkg/ScsiBusDxe: don't produce ScsiIo for nonexistent LUNs, part 1
The SPC-4 spec says about the INQUIRY data, in "Table 138 -- Peripheral
qualifier":

> Qualifier = 011b  The device server is not capable of supporting a
>                   peripheral device on this logical unit. For this
>                   peripheral qualifier the peripheral device type shall
>                   be set to 1Fh. All other peripheral device type values
>                   are reserved for this peripheral qualifier.

Accordingly, the DiscoverScsiDevice() function returns FALSE if
Peripheral_Qualifier is 3 decimal, but Peripheral_Type differs from 1Fh.
This is a valid sanity check -- such combinations are reserved.

When Peripheral_Qualifier is 3, and Peripheral_Type is 1Fh, then
DiscoverScsiDevice() returns TRUE. While this combination is not reserved,
returning TRUE for it is incorrect: Peripheral_Type 1Fh stands for
"Unknown or no device type", and this combination is returned in
particular when the INQUIRY command was directed to a nonexistent LUN.
Quoting the spec:

> In response to an INQUIRY command received by an incorrect logical unit,
> the SCSI target device shall return the INQUIRY data with the peripheral
> qualifier set to the value defined in 6.4.2. [...]
>
> [...]
>
> The PERIPHERAL QUALIFIER field and PERIPHERAL DEVICE TYPE field identify
> the peripheral device connected to the logical unit. If the SCSI target
> device is not capable of supporting a peripheral device connected to
> this logical unit, the device server shall set these fields to 7Fh
> (i.e., PERIPHERAL QUALIFIER field set to 011b and PERIPHERAL DEVICE TYPE
> field set to 1Fh).

The consequence of this bug is that for each nonexistent Target/LUN pair,
we produce a useless ScsiIo protocol interface. The internal
"ScsiIoDevice->ScsiDeviceType" field will be set to 0x1f, and it will be
returned to higher-level SCSI drivers when they call
ScsiIo->GetDeviceType().

Given that 0x1f means "Unknown or no device type", no higher-level driver
can ever support it, so these ScsiIo protocol interfaces are useless.

The fix is to return FALSE for the (Peripheral_Qualifier=3,
Peripheral_Type=0x1f) combination. With that however we reject the whole
Peripheral_Qualifier=3 space (justifiedly -- see the definition above),
which lets us simplify the code.

Hao Wu 7c115e775b MdeModulePkg/ScsiDiskDxe: Fix undefined behavior in signed left shift
In function GetMediaInfo(), the following expression:
ScsiDiskDevice->BlkIo.Media->LastBlock =  (Capacity10->LastLba3 << 24) |
                                          (Capacity10->LastLba2 << 16) |
                                          (Capacity10->LastLba1 << 8)  |
                                           Capacity10->LastLba0;
will involve undefined behavior in signed left shift operations.

Since Capacity10->LastLbaX is of type UINT8, and
ScsiDiskDevice->BlkIo.Media->LastBlock is of type UINT64. Therefore,
Capacity10->LastLbaX will be promoted to int (32 bits, signed) first,
and then perform the left shift operation.

According to the C11 spec, Section 6.5.7:
4 The result of E1 << E2 is E1 left-shifted E2 bit positions; vacated
  bits are filled with zeros. If E1 has an unsigned type, the value
  of the result is E1 * 2^E2 , reduced modulo one more than the
  maximum value representable in the result type. If E1 has a signed
  type and nonnegative value, and E1 * 2^E2 is representable in the
  result type, then that is the resulting value; otherwise, the
  behavior is undefined.

So if bit 7 of Capacity10->LastLba3 is 1, (Capacity10->LastLba3 << 24)
will be out of the range within int type. The undefined behavior of the
signed left shift will lead to a potential of setting the high 32 bits
of ScsiDiskDevice->BlkIo.Media->LastBlock to 1 during the cast from type
int to type UINT64.

This commit will add an explicit UINT32 type cast for
Capacity10->LastLba3 to resolve this issue.

Laszlo Ersek ce1647fc60 MdeModulePkg: ScsiDiskDxe: cope with broken "Supported VPD Pages" VPD page
The USB flash drive with Vendor ID 0x1516 (CompUSA) and Product ID 0x6221
returns a broken "Supported VPD Pages" VPD page. In particular, the
PageLength field has the invalid value 0x0602 (decimal 1538).

This prevents the loop from terminating that scans for the Block Limits
VPD page code in ScsiDiskInquiryDevice():

        for (Index = 0; Index < PageLength; Index++) {

because the Index variable has type UINT8, and it wraps from 255 to 0,
without ever reaching PageLength (1538), and because
EFI_SCSI_PAGE_CODE_BLOCK_LIMITS_VPD does not occur at offsets 0 through
255.

* The fix is not to change the type of Index to UINT16 or a wider type.
  Namely, section

    7.8.14 Supported VPD Pages VPD page

  in the "SCSI Primary Commands - 4" (SPC-4) specification names the
  following requirement:

    The supported VPD page list shall contain a list of all VPD page codes
    (see 7.8) implemented by the logical unit in ascending order beginning
    with page code 00h.

  Since page codes are 8-bit unsigned quantities, it follows that the
  maximum size for the Supported VPD Pages VPD page is 0x100 bytes, in
  which every possible page code (0x00 through 0xFF) will be found, before
  the UINT8 offset wraps around.

  (EFI_SCSI_SUPPORTED_VPD_PAGES_VPD_PAGE.SupportedVpdPageList is correctly
  sized as well, in "MdePkg/Include/IndustryStandard/Scsi.h".)

* Instead, add sanity checks that enforce the above requirement. If the
  device breaks the spec, simply fall back to the "Block Limits page
  absent" case.

Otherwise, a 'reconnect -r' action when an ISCSI device is attached will
cause system hang.

As ScsiDisk and ScsiBus driver are used to manage SCSI or ATAPI devices,
the timeout value is updated to 30s to follow ATA/ATAPI spec in which

The change is used to solve device compatibility issue found with a TEAC

When reading data from non-blockingly from a CD-ROM logic partition, the

 Completes

In PartitionDxe, if the 'Lba' and 'BufferSize' parameters passed to
function PartitionReadBlocksEx() are invalid, the function will issue a
blocking ReadDisk call (in function ProbeMediaStatusEx()).

In DiskIoDxe, blocking I/O request will wait for all the non-blocking I/O
requests to complete first before sending down the blocking request.

If the Tpl of the async I/O callback in ScsiDiskDxe is TPL_CALLBACK and
Sub-task 1 (UnderRun) succeeds but Sub-task 2 (OverRun) fails with an
invalid parameter, DiskIoDxe will wait indefinitely for the event created
by ScsiDiskDxe of Sub-task 1 to signal.

Hence, this commit will raise the Tpl of async IO callback in ScsiDiskDxe
to TPL_NOTIFY so that the indefinite wait in DiskIoDxe can be avoided.

Laszlo Ersek 5abc2a70da MdeModulePkg: ScsiDiskDxe: adapt SectorCount when shortening transfers
The specification of the EFI_EXT_SCSI_PASS_THRU_PROTOCOL.PassThru()
function documents the EFI_BAD_BUFFER_SIZE return status, and the
EFI_EXT_SCSI_STATUS_HOST_ADAPTER_DATA_OVERRUN_UNDERRUN host adapter
status.

These allow an EFI_EXT_SCSI_PASS_THRU_PROTOCOL implementation to request
higher layers in the stack (in this instance, UefiScsiLib and ScsiDiskDxe)
to break up the transfer into smaller pieces.

These conditions percolate up the stack correctly: the retry loops in
ScsiDiskDxe's ScsiDiskReadSectors() and ScsiDiskWriteSectors() functions
correctly and transparently update the transfer size (ByteCount),
accommodating any shortening requested by lower levels of the stack. After
the loop -- if the request ultimately succeeds -- SectorCount is even
recalculated from the final ByteCount, to see how many sectors the outer
loop should advance.

However, the inner (ie. retry) loops both have the same error: when the
underlying protocols request the transfer to be shortened, the decrease in
transfer size (ie. ByteCount) should immediately be reflected in
SectorCount. Otherwise the sector count encoded in the CDB will exceed the
transfer size, which is a permanent error.

This issue has been witnessed while booting

  en_windows_8.1_pro_n_vl_with_update_x86_dvd_6051127.iso

on the 32-bit build of OVMF, from a virtio-scsi CD-ROM:

(1) "cdboot.efi" correctly requested (from far atop) a long read:

    Timeout=940000000
    CdbLength=10
    DataDir=Read
    InTransferLength=134215680
    OutTransferLength=0
    SenseDataLength=108

    Cdb: 28 00 00 00 25 DD 00 FF FF 00
         ^     ^^^^^^^^^^^    ^^^^^
         |          |            |
         |          |     number of 2KB sectors to read,
         |          |     corresponding to 2048 * 65535 = 134215680 bytes
         |          |     (see InTransferLength above)
         |          |
         |   LBA to read from
         |
      READ (10)

(2) In turn, the EFI_EXT_SCSI_PASS_THRU_PROTOCOL.PassThru() function
    provided by "OvmfPkg/VirtioScsiDxe/VirtioScsi.c" asked for the request
    to be shortened:

    InTransferLength=16776704
    OutTransferLength=16776704
    SenseDataLength=0
    HostAdapterStatus=EFI_EXT_SCSI_STATUS_HOST_ADAPTER_DATA_OVERRUN_UNDERRUN
    TargetStatus=0
    Status=EFI_BAD_BUFFER_SIZE

(3) Then ScsiDiskReadSectors() in
    "MdeModulePkg/Bus/Scsi/ScsiDiskDxe/ScsiDisk.c" retried the request
    with correctly shortened transfer length, but incorrectly unchanged
    sector count:

    Timeout=940000000
    CdbLength=10
    DataDir=Read
    InTransferLength=16776704 <--- updated as requested
    OutTransferLength=0
    SenseDataLength=108

    Cdb: 28 00 00 00 25 DD 00 FF FF 00
         ^     ^^^^^^^^^^^    ^^^^^
         |          |            |
         |          |       not changed!
         |          |
         |   LBA to read from
         |
      READ (10)

(4) Since 65535 sectors of 2KB each wouldn't fit in a buffer of approx.
    16MB, QEMU's virtio-scsi controller unconditionally rejected this
    request with VIRTIO_SCSI_S_OVERRUN, which VirtioScsiDxe then mapped
    to:

    InTransferLength=16776704
    OutTransferLength=0
    SenseDataLength=0
    HostAdapterStatus=EFI_EXT_SCSI_STATUS_HOST_ADAPTER_DATA_OVERRUN_UNDERRUN
    TargetStatus=0
    Status=EFI_DEVICE_ERROR

(5) After two more tries of the same, ScsiDiskDxe passed up the error,
    which ultimately caused "cdboot.efi" to BSOD.

Many thanks to Larry Cleeton from Microsoft for helping debug
"cdboot.efi".
