Note that the flash memory area is only created when a -pflash argument is

When virtio-net is used with the socket netdev backend, the backend
can be busy and not able to collect new packets.
In this case, net_socket_receive() returns 0 and registers a poll function
to detect when the socket is ready again.
In virtio_net_tx_bh(), virtio_net_flush_tx() forwards the 0, the virtio
notifications are disabled and the function is not re-scheduled, waiting
for the backend to be ready.
When the socket netdev backend is again able to send packets, the poll
function re-starts to flush remaining packets. This is done by
calling virtio_net_tx_complete(). It re-enables notifications and calls
again virtio_net_flush_tx().
But it seems if virtio_net_flush_tx() reaches the tx_burst value all
the queue is not flushed and no new notification is sent to re-schedule
virtio_net_tx_bh(). Nothing re-start to flush the queue and remaining
packets are stuck in the queue.
To fix that, detect in virtio_net_tx_complete() if virtio_net_flush_tx()
has been stopped by tx_burst and if yes re-schedule the bottom half
function virtio_net_tx_bh() to flush the remaining packets.
This is what is done in virtio_net_tx_bh() when the virtio_net_flush_tx()
is synchronous, and completly by-passed when the operation needs to be
asynchronous.

As of the kernel commit linked below, Linux ingests an RNG seed
passed as part of the environment block by the bootloader or firmware.
This mechanism works across all different environment block types,
generically, which pass some block via the second firmware argument. On
malta, this has been tested to work when passed as an argument from
U-Boot's linux_env_set.
As is the case on most other architectures (such as boston), when
booting with `-kernel`, QEMU, acting as the bootloader, should pass the
RNG seed, so that the machine has good entropy for Linux to consume. So
this commit implements that quite simply by using the guest random API,
which is what is used on nearly all other archs too. It also
reinitializes the seed on reboot, so that it is always fresh.

The code for handling the reset level count in the Resettable code
has two issues:
The reset count is only decremented for the 1->0 case. This means
that if there's ever a nested reset that takes the count to 2 then it
will never again be decremented. Eventually the count will exceed
the '50' limit in resettable_phase_enter() and QEMU will trip over
the assertion failure. The repro case in issue 1266 is an example of
this that happens now the SCSI subsystem uses three-phase reset.
Secondly, the count is decremented only after the exit phase handler
is called. Moving the reset count decrement from "just after" to
"just before" calling the exit phase handler allows
resettable_is_in_reset() to return false during the handler
execution.
This simplifies reset handling in resettable devices. Typically, a
function that updates the device state will just need to read the
current reset state and not anymore treat the "in a reset-exit
transition" as a special case.
Note that the semantics change to the *_is_in_reset() functions
will have no effect on the current codebase, because only two
devices (hw/char/cadence_uart.c and hw/misc/zynq_sclr.c) currently
call those functions, and in neither case do they do it from the
device's exit phase methed.

When a RAMBlockNotifier is added, ->ram_block_added() is called with all
existing RAMBlocks. There is no equivalent ->ram_block_removed() call
when a RAMBlockNotifier is removed.
The util/vfio-helpers.c code (the sole user of RAMBlockNotifier) is fine
with this asymmetry because it does not rely on RAMBlockNotifier for
cleanup. It walks its internal list of DMA mappings and unmaps them by
itself.
Future users of RAMBlockNotifier may not have an internal data structure
that records added RAMBlocks so they will need ->ram_block_removed()
callbacks.
This patch makes ram_block_notifier_remove() symmetric with respect to
callbacks. Now util/vfio-helpers.c needs to unmap remaining DMA mappings
after ram_block_notifier_remove() has been called. This is necessary
since users like block/nvme.c may create additional DMA mappings that do
not originate from the RAMBlockNotifier.

The previous implementation would iterate over the fid table for
lookup operations, resulting in an operation with O(n) complexity on
the number of open files and poor cache locality -- for every open,
stat, read, write, etc operation.
This change uses a hashtable for this instead, significantly improving
the performance of the 9p filesystem. The runtime of NixOS's simple
installer test, which copies ~122k files totalling ~1.8GiB from 9p,
decreased by a factor of about 10.

JEDEC STANDARD JESD216 for Serial Flash Discovery Parameters (SFDP)
provides a mean to describe the features of a serial flash device
using a set of internal parameter tables.
This is the initial framework for the RDSFDP command giving access to
a private SFDP area under the flash. This area now needs to be
populated with the flash device characteristics, using a new
'sfdp_read' handler under FlashPartInfo.

Investigating why some BMC models are so slow compared to a plain ARM
virt machines I did some profiling of:
./qemu-system-arm -M romulus-bmc -nic user \
-drive
file=obmc-phosphor-image-romulus.static.mtd,format=raw,if=mtd \
-nographic -serial mon:stdio
And saw that object_class_dynamic_cast_assert was dominating the
profile times. We have a number of cases in this model of the SSI bus.
As the class is static once the object is created we just cache it and
use it instead of the dynamic case macros.

I think when Klaus ported his slave mode changes from the original patch
series to the rewritten I2C module, he changed the behavior of the first
byte that is received by the slave device.
What's supposed to happen is that the AspeedI2CBus's slave device's
i2c_event callback should run, and if the event is "send_async", then it
should populate the byte buffer with the 8-bit I2C address that is being
sent to. Since we only support "send_async", the lowest bit should
always be 0 (indicating that the master is requesting to send data).
This is the code Klaus had previously, for reference. [1]
switch (event) {
case I2C_START_SEND:
bus->buf = bus->dev_addr << 1;
bus->buf &= I2CD_BYTE_BUF_RX_MASK;
bus->buf <<= I2CD_BYTE_BUF_RX_SHIFT;
bus->intr_status |= (I2CD_INTR_SLAVE_ADDR_RX_MATCH | I2CD_INTR_RX_DONE);
aspeed_i2c_set_state(bus, I2CD_STXD);
break;

Rather than poking directly into RAM, add the bootinfo block as a proper
ROM, so that it's restored when rebooting the system. This way, if the
guest corrupts any of the bootinfo items, but then tries to reboot,
it'll still be restored back to normal as expected.
Then, since the RNG seed needs to be fresh on each boot, regenerate the
RNG seed in the ROM when reseting the CPU.

Following a change on the kernel side (see link), pass BI_RNG_SEED
instead of BI_VIRT_RNG_SEED. This should have no impact on
compatibility, as there will simply be no effect if it's an old kernel,
which is how things have always been. We then use this as an opportunity
to add this to q800, since now we can, which is a nice improvement.

Currently the microdrive code uses device_legacy_reset() to reset
itself, and has its reset method call reset on the IDE bus as the
last thing it does. Switch to using device_cold_reset().
The only concrete microdrive device is the TYPE_DSCM1XXXX; it is not
command-line pluggable, so it is used only by the old pxa2xx Arm
boards 'akita', 'borzoi', 'spitz', 'terrier' and 'tosa'.
You might think that this would result in the IDE bus being
reset automatically, but it does not, because the IDEBus type
does not set the BusClass::reset method. Instead the controller
must explicitly call ide_bus_reset(). We therefore leave that
call in md_reset().
Note also that because the PCMCIA card device is a direct subclass of
TYPE_DEVICE and we don't model the PCMCIA controller-to-card
interface as a qbus, PCMCIA cards are not on any qbus and so they
don't get reset when the system is reset. The reset only happens via
the dscm1xxxx_attach() and dscm1xxxx_detach() functions during
machine creation.
Because our aim here is merely to try to get rid of calls to the
device_legacy_reset() function, we leave these other dubious
reset-related issues alone. (They all stem from this code being
absolutely ancient.)

Resetting a guest that has Hyper-V VMBus support enabled triggers a QEMU
assertion failure:
hw/hyperv/hyperv.c:131: synic_reset: Assertion `QLIST_EMPTY(&synic->sint_routes)' failed.
This happens both on normal guest reboot or when using "system_reset" HMP
command.
The failing assertion was introduced by commit 64ddecc88b ("hyperv: SControl is optional to enable SynIc")
to catch dangling SINT routes on SynIC reset.
The root cause of this problem is that the SynIC itself is reset before
devices using SINT routes have chance to clean up these routes.
Since there seems to be no existing mechanism to force reset callbacks (or
methods) to be executed in specific order let's use a similar method that
is already used to reset another interrupt controller (APIC) after devices
have been reset - by invoking the SynIC reset from the machine reset
handler via a new x86_cpu_after_reset() function co-located with
the existing x86_cpu_reset() in target/i386/cpu.c.
Opportunistically move the APIC reset handler there, too.
Fixes: 64ddecc88b ("hyperv: SControl is optional to enable SynIc") # exposed the bug

Currently the vwm_pvscsi controller resets individual SCSI devices
with the device_legacy_reset() function. The only difference between
this and device_cold_reset() is that device_legacy_reset() resets the
device but not any child qbuses it might have.
In this case, no SCSI device has a child qbus, so the functions have
the same behaviour. Switch to device_cold_reset() to move away from
using the deprecated function, and bring this SCSI controller in to
line with what all the others do.

In the SCSI subsystem we currently use the legacy functions
qdev_reset_all() and qbus_reset_all(). These perform a recursive
reset, starting from either a qbus or a qdev. However they do not
permit any of the devices in the tree to use three-phase reset,
because device reset goes through the device_legacy_reset() function
that only calls the single DeviceClass::reset method.
Switch to using the device_cold_reset() and bus_cold_reset()
functions. These also perform a recursive reset, where first the
children are reset and then finally the parent, but they use the new
(...in 2020...) Resettable mechanism, which supports both the old
style single-reset method and also the new 3-phase reset handling.
Since no devices attached to SCSI buses currently try to use 3-phase
reset, this should be a no-behaviour-change commit which just reduces
the use of a deprecated API.

The pSeries machine never bothered with the common machine->fdt
attribute. We do all the FDT related work using spapr->fdt_blob.
We're going to introduce a QMP/HMP command to dump the FDT, which will
rely on setting machine->fdt properly to work across all machine
archs/types.
Let's set machine->fdt in two places where we manipulate the FDT:
spapr_machine_reset() and CAS. There are other places where the FDT is
manipulated in the pSeries machines, most notably the hotplug/unplug
path. For now we'll acknowledge that we won't have the most accurate
representation of the FDT, depending on the current machine state, when
using this QMP/HMP fdt command. Making the internal FDT representation
always match the actual FDT representation that the guest is using is a
problem for another day.
spapr->fdt_blob is left untouched for now. To replace it with
machine->fdt, since we're migrating spapr->fdt_blob, we would need to
migrate machine->fdt as well. This is something that we would like to to
do keep our code simpler but it's also a work we'll leave for later.

may have to be disabled or the model split between 440 and older.
Newer SoCs (regardless of their PPC core, e.g. 405EX) may have an

To boot S-mode firmware payload like EDK2 from persistent
flash storage, qemu needs to pass the flash address as the
next_addr in fw_dynamic_info to the opensbi.
When both -kernel and -pflash options are provided in command line,
the kernel (and initrd if -initrd) will be copied to fw_cfg table.
The S-mode FW will load the kernel/initrd from fw_cfg table.
If only pflash is given but not -kernel, then it is the job of
of the S-mode firmware to locate and load the kernel.
In either case, update the kernel_entry with the flash address
so that the opensbi can jump to the entry point of the S-mode
firmware.

VIRTIO_SCSI_EVT_RESET_RESCAN or VIRTIO_SCSI_EVT_RESET_REMOVED events
are reported (when disk hotplug/hotunplug events occur). SCSI layer
on Solaris depends on this sense data, and hence does not handle disk
hotplug/hotunplug events.
When the disk inventory changes, use the bus unit attention mechanism
to return a CHECK_CONDITION status with sense data of 0x06/0x3F/0x0E
(sense code REPORTED_LUNS_CHANGED). The first device on the bus to
execute a command successfully will report and consume the unit

[Jonah: @virtio_list duplicates information that already exists in
the QOM composition tree. However, extracting necessary information
from this tree seems to be a bit convoluted.
Instead, we still create our own list of realized virtio devices
but use @qmp_qom_get with the device's canonical QOM path to confirm
that the device exists and is realized. If the device exists but
is actually not realized, then we remove it from our list (for
synchronicity to the QOM composition tree).
Also, the QMP command @x-query-virtio is redundant as @qom-list
and @qom-get are sufficient to search '/machine/' for realized
virtio devices. However, @x-query-virtio is much more convenient
in listing realized virtio devices.]

It's true that when vcpus<=255 we don't require the length of 32bit APIC
IDs. However here since we already have EIM=ON it means the hypervisor
will declare the VM as x2apic supported (e.g. VT-d ECAP register will have
EIM bit 4 set), so the guest should assume the APIC IDs are 32bits width
even if vcpus<=255. In short, commit 77250171bd breaks any simple cmdline
that wants to boot a VM with >=9 but <=255 vcpus with:
-device intel-iommu,intremap=on
For anyone who does not want to enable x2apic, we can use eim=off in the
intel-iommu parameters to skip enabling KVM x2apic.
This partly reverts commit 77250171bd, while
keeping the valid bit on checking split irqchip, but revert the other change.
One thing to mention is that this patch may break migration compatibility
of such VM, however that's probably the best thing we can do, because the
old behavior was simply wrong and not working for >8 vcpus. For <=8 vcpus,
there could be a light guest ABI change (by enabling KVM x2apic after this
patch), but logically it shouldn't affect the migration from working.
Also, this is not the 1st commit to change x2apic behavior. Igor provided
a full history of how this evolved for the past few years:

This is caused by the newer (destination) VM requiring a bigger BAR0
alignment because it has to cover a bigger configuration space, which
isn't actually needed since those additional config fields are not
active (write-zeroes/discard).

This is the first step towards moving all device config size calculation
logic into the virtio core code. In particular, this adds a struct that
contains all the necessary information for common virtio code to be able
to calculate the final config size for a device. This is expected to be
used with the new virtio_get_config_size helper, which calculates the
final length based on the provided host features.
This builds on top of already existing code like VirtIOFeature and
virtio_feature_get_config_size(), but adds additional fields, as well as
sanity checking so that device-specifc code doesn't have to duplicate it.
An example usage would be:
static const VirtIOFeature dev_features[] = {
{.flags = 1ULL << FEATURE_1_BIT,
.end = endof(struct virtio_dev_config, feature_1)},
{.flags = 1ULL << FEATURE_2_BIT,
.end = endof(struct virtio_dev_config, feature_2)},
{}
};
static const VirtIOConfigSizeParams dev_cfg_size_params = {
.min_size = DEV_BASE_CONFIG_SIZE,
.max_size = sizeof(struct virtio_dev_config),
.feature_sizes = dev_features
};
// code inside my_dev_device_realize()
size_t config_size = virtio_get_config_size(&dev_cfg_size_params,
host_features);
virtio_init(vdev, VIRTIO_ID_MYDEV, config_size);
Currently every device is expected to write its own boilerplate from the
example above in device_realize(), however, the next step of this
transition is moving VirtIOConfigSizeParams into VirtioDeviceClass,
so that it can be done automatically by the virtio initialization code.
All of the users of virtio_feature_get_config_size have been converted
to use virtio_get_config_size so it's no longer needed and is removed
with this commit.

g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,
for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.
This commit only touches allocations with size arguments of the form
sizeof(T).

the setup data, use the selection of the kernel as a trigger to
re-initialize the RNG seed, just like we do on reboot, to preserve
forward secrecy.

CHS-based disk utilities and operating systems may adjust the logical
geometry of a hard drive to cope with the expectations or limitations
of software using the ATA INITIALIZE_DEVICE_PARAMETERS command.
Prior to this patch, INITIALIZE_DEVICE_PARAMETERS was a nop that
always returned success, raising the possibility of data loss or
corruption if the CHS<->LBA translation redirected a write to the
wrong sector.
* hw/ide/core.c
ide_reset():
Reset the logical CHS geometry of the hard disk when the power-on
defaults feature is enabled.
cmd_specify():
a) New function implementing INITIALIZE_DEVICE_PARAMETERS.
b) Ignore calls for empty or ATAPI devices.

Prior to this patch, cmd_exec_dev_diagnostic relied upon
ide_set_signature to clear the device register. While the
preservation of the drive bit by ide_set_signature is necessary for
the DEVICE RESET, IDENTIFY DEVICE, and READ SECTOR commands,
ATA/ATAPI-6 specifies that "DEV shall be cleared to zero" for EXECUTE
DEVICE DIAGNOSTIC.
This deviation was uncovered by the ATACT Device Testing Program
written by Hale Landis.

Commit 5f76a7aac1 is looking harmless from
the first glance, but it has changed things a lot. 'libvirt' uses it to
detect that it should follow new initialization way and this changes
things considerably. With this procedure followed, blockdev_init() is
not called anymore and thus block_acct_setup() helper is not called.
This means in particular that defaults for block accounting statistics
are changed and account_invalid/account_failed are actually initialized
as false instead of true originally.
This commit changes things to match original world. There are the following
constraints:
* new default value in block_acct_init() is set to true
* block_acct_setup() inside blockdev_init() is called before
blkconf_apply_backend_options()
* thus newly created option in block device properties has precedence if
specified

The "msi-parent" property can be used on the PCI node when MSIs do not
contain sideband data (device IDs) [1]. In QEMU, MSI transactions
contain the requester ID, so the PCI node should use the "msi-map"
property instead of "msi-parent". In our case the property describes an
identity map between requester ID and sideband data.
This fixes a warning when passing the DTB generated by QEMU to dtc,
following a recent change to the GICv3 node:

In the case that exec' function get invoked, such as the live-update feature

If setup_data is being read into a specific memory location, then
generally the setup_data address parameter is read first, so that the
caller knows where to read it into. In that case, we should return
setup_data containing the absolute addresses that are hard coded and
determined a priori. This is the case when kernels are loaded by BIOS,
for example. In contrast, when setup_data is read as a file, then we
shouldn't modify setup_data, since the absolute address will be wrong by
definition. This is the case when OVMF loads the image.
This allows setup_data to be used like normal, without crashing when EFI
tries to use it.
(As a small development note, strangely, fw_cfg_add_file_callback() was
exported but fw_cfg_add_bytes_callback() wasn't, so this makes that
consistent.)

Let's use the reserved pool of simulated PCI groups to allow intercept
devices to have separate groups from interpreted devices as some group
values may be different. If we run out of simulated PCI groups, subsequent
intercept devices just get the default group.
Furthermore, if we encounter any PCI groups from hostdevs that are marked
as simulated, let's just assign them to the default group to avoid
conflicts between host simulated groups and our own simulated groups.

If the ZPCI_OP ioctl reports that is is available and usable, then the
underlying KVM host will enable load/store intepretation for any guest
device without a SHM bit in the guest function handle. For a device that
will be using interpretation support, ensure the guest function handle
matches the host function handle; this value is re-checked every time the
guest issues a SET PCI FN to enable the guest device as it is the only
opportunity to reflect function handle changes.
By default, unless interpret=off is specified, interpretation support will
always be assumed and exploited if the necessary ioctl and features are
available on the host kernel. When these are unavailable, we will silently
revert to the interception model; this allows existing guest configurations
to work unmodified on hosts with and without zPCI interpretation support,
allowing QEMU to choose the best support model available.

An abort happens in ohci_frame_boundary() when ohci->done is 0 [1].
``` c
static void ohci_frame_boundary(void *opaque)
{
// ...
if (ohci->done_count == 0 && !(ohci->intr_status & OHCI_INTR_WD)) {
if (!ohci->done)
abort(); <----------------------------------------- [1]
```
This was reported in https://bugs.launchpad.net/qemu/+bug/1911216/,
https://lists.gnu.org/archive/html/qemu-devel/2021-06/msg03613.html, and
https://gitlab.com/qemu-project/qemu/-/issues/545. I can still reproduce it with
the latest QEMU.
This happends due to crafted ED with putting ISO_TD at physical address 0.
Suppose ed->head & OHCI_DPTR_MASK is 0 [2], and we memset 0 to the phyiscal
memory from 0 to sizeof(ohci_iso_td). Then, starting_frame [3] and frame_count
[4] are both 0. As we can control the value of ohci->frame_number (0 to 0x1f,
suppose 1), we then control the value of relative_frame_number to be 1 [6]. The
control flow goes to [7] where ohci->done is 0. Have returned from
ohci_service_iso_td(), ohci_frame_boundary() will abort() [1].
``` c
static int ohci_service_iso_td(OHCIState *ohci, struct ohci_ed *ed)
{
// ...
addr = ed->head & OHCI_DPTR_MASK; // <--------------------- [2]
if (ohci_read_iso_td(ohci, addr, &iso_td)) { // <-------- [3]
// ...
starting_frame = OHCI_BM(iso_td.flags, TD_SF); // <-------- [4]
frame_count = OHCI_BM(iso_td.flags, TD_FC); // <-------- [5]
relative_frame_number = USUB(ohci->frame_number, starting_frame);
// <-------- [6]
if (relative_frame_number < 0) {
return 1;
} else if (relative_frame_number > frame_count) {
// ...
ohci->done = addr; // <-------- [7]
// ...
}
```
As only (afaik) a guest root user can manipulate ED, TD and the physical memory,
this assertion failure is not a security bug.
The idea to fix this issue is to drop ohci_service_iso_td() if ed->head &
OHCI_DPTR_MASK is 0, which is similar to the drop operation for
ohci_service_ed_list() when head is 0. Probably, a similar issue is in
ohci_service_td(). I drop ohci_service_td() if ed->head & OHCI_DPTR_MASK is 0.

Currently armv7m_load_kernel() takes the size of the block of memory
where it should load the initial guest image, but assumes that it
should always load it at address 0. This happens to be true of all
our M-profile boards at the moment, but it isn't guaranteed to always
be so: M-profile CPUs can be configured (via init-svtor and
init-nsvtor, which match equivalent hardware configuration signals)
to have the initial vector table at any address, not just zero. (For
instance the Teeny board has the boot ROM at address 0x0200_0000.)
Add a base address argument to armv7m_load_kernel(), so that
callers now pass in both base address and size. All the current
callers pass 0, so this is not a behaviour change.

Arm system emulation targets always have TARGET_BIG_ENDIAN clear, so
there is no need to have handling in armv7m_load_kernel() for the
case when it is defined. Remove the unnecessary code.
Side notes:
* our M-profile implementation is always little-endian (that is, it
makes the IMPDEF choice that the read-only AIRCR.ENDIANNESS is 0)
* if we did want to handle big-endian ELF files here we should do it
the way that hw/arm/boot.c:arm_load_elf() does, by looking at the
ELF header to see what endianness the file itself is

When running under Xen and the guest reboots, it boots into a new domain
with a new QEMU process (and a new swtpm process if using the emulator
backend). The existing reset function is triggered just before the old
QEMU process exists which causes QEMU to startup the TPM backend and
then immediately shut it down. This is probably harmless but when using
the emulated backend, it wastes CPU and IO time reloading state, etc.
Fix this by calling the reset function directly from realize() when
running under Xen. During a reboot, this will be called by the QEMU
process for the new domain.

Booting using "Direct Kernel Boot" for PolarFire SoC & skipping u-boot
entirely is probably not advisable, but it does at least show signs of
life. Recent Linux kernel versions make use of peripherals that are
missing definitions in QEMU and lead to kernel panics. These issues
almost certain rear their head for other methods of booting, but I was
unable to figure out a suitable HSS version that is recent enough to
support these peripherals & works with QEMU.
With these peripherals added, booting a kernel with the following hangs
hangs waiting for the system controller's hwrng, but the kernel no
longer panics. With the Linux driver for hwrng disabled, it boots to
console.
qemu-system-riscv64 -M microchip-icicle-kit \
-m 2G -smp 5 \
-kernel $(vmlinux_bin) \
-dtb $(dtb)\
-initrd $(initramfs) \
-display none -serial null \
-serial stdio
More peripherals are added than strictly required to fix the panics in
the hopes of avoiding a replication of this problem in the future.
Some of the peripherals which are in the device tree for recent kernels
are implemented in the FPGA fabric. The eMMC/SD mux, which exists as
an unimplemented device is replaced by a wider entry. This updated
entry covers both the mux & the remainder of the FPGA fabric connected
to the MSS using Fabric Interrconnect (FIC) 3.

In scsi_req_parse_cdb(), if the CDB length implied by the command type
exceeds the initialized portion of the command buffer, reject the request.
Rejected requests are recorded by the `scsi_req_parse_bad` trace event.
On example of a bug detected by this check is SunOS's use of interleaved
DMA and non-DMA commands. This guest behavior currently causes QEMU to
parse uninitialized memory as a SCSI command, with unpredictable
outcomes.
With the new check in place:
* QEMU consistently creates a trace event and rejects the request.
* SunOS retries the request(s) and is able to successfully boot from
disk.

When a SCSI command is received from the guest, the CDB length implied
by the first byte might exceed the number of bytes the guest sent. In
this case scsi_req_new() will read uninitialized data, causing
unpredictable behavior.
Adds the buf_len parameter to scsi_req_new() and plumbs it through the
call stack.

[Fill in correct length for adapters other than ESP. - Paolo]

Per investigation on the linked ticket, SunOS issues a SCSI bus reset
to the ESP as part of its boot sequence. If this ESP command doesn't
cause devices to assert sense flag UNIT ATTENTION, SunOS will consider
the CD-ROM device to be non-compliant with Common Command Set (CCS).
In this condition, the SunOS installer's early userspace doesn't set
the installation source location to sr0 and the miniroot copy fails.
