linux-user: Make sigaltstack stacks per-thread
The alternate signal stack set up by the sigaltstack syscall is
supposed to be per-thread. We were incorrectly implementing it as
process-wide. This causes problems for guest binaries that rely on
this. Notably the Go runtime does, and so we were seeing crashes
caused by races where two guest threads might incorrectly both
execute on the same stack simultaneously.
Replace the global target_sigaltstack_used with a field
sigaltstack_used in the TaskState, and make all the references to the
old global instead get a pointer to the TaskState and use the field.

hw/arm/boot: Further improve initrd positioning code
In commit
e6b2b20d9735d4ef we made the boot loader code try to avoid
putting the initrd on top of the kernel. However the expression used
to calculate the start of the initrd:
info->initrd_start = info->loader_start +
MAX(MIN(info->ram_size / 2, 128 * 1024 * 1024), kernel_size);
incorrectly uses 'kernel_size' as the offset within RAM of the
highest address to avoid. This is incorrect because the kernel
doesn't start at address 0, but slightly higher than that. This
means that we can still incorrectly end up overlaying the initrd on
the kernel in some cases, for example:
* The kernel's image_size is 0x0a7a8000
* The kernel was loaded at 0x40080000
* The end of the kernel is 0x4A828000
* The DTB was loaded at 0x4a800000
To get this right we need to track the actual highest address used
by the kernel and use that rather than kernel_size. We already
set image_low_addr and image_high_addr for ELF images; set them
also for the various other image types we support, and then use
image_high_addr as the lowest allowed address for the initrd.
(We don't use image_low_addr, but we set it for consistency
with the existing code path for ELF files.)

vmstate.h: Type check VMSTATE_STRUCT_VARRAY macros
The VMSTATE_STRUCT_VARRAY_UINT32 macro is intended to handle
migrating a field which is an array of structs, but where instead of
migrating the entire array we only migrate a variable number of
elements of it.
The VMSTATE_STRUCT_VARRAY_POINTER_UINT32 macro is intended to handle
migrating a field which is of pointer type, and points to a
dynamically allocated array of structs of variable size.
We weren't actually checking that the field passed to
VMSTATE_STRUCT_VARRAY_UINT32 really is an array, with the result that
accidentally using it where the _POINTER_ macro was intended would
compile but silently corrupt memory on migration.
Add type-checking that enforces that the field passed in is
really of the right array type. This applies to all the VMSTATE
macros which use flags including VMS_VARRAY_* but not VMS_POINTER.

- We are not indicating VIRTIO_BALLOON_F_MUST_TELL_HOST, therefore
guests (esp. legacy guests) will reuse pages without deflating,
turning the PBP stale. Adding that would require compat handling.
Instead, let's use the PBP only temporarily, when processing one bulk of
inflation requests. This will keep guest_page_size > 4k working (with
Linux guests). There is nothing to do for deflation requests anymore.
The pbp is only used for a limited amount of time.

virtio-balloon: Fix QEMU crashes on pagesize > BALLOON_PAGE_SIZE
We are using the wrong functions to set/clear bits, effectively touching
multiple bits, writing out of range of the bitmap, resulting in memory
corruptions. We have to use set_bit()/clear_bit() instead.
Can easily be reproduced by starting a qemu guest on hugetlbfs memory,
inflating the balloon. QEMU crashes. This never could have worked
properly - especially, also pages would have been discarded when the
first sub-page would be inflated (the whole bitmap would be set).
While testing I realized, that on hugetlbfs it is pretty much impossible
to discard a page - the guest just frees the 4k sub-pages in random order
most of the time. I was only able to discard a hugepage a handful of
times - so I hope that now works correctly.

docs: clarify multiqueue vs multiple virtqueues
The vhost-user specification does not explain when
VHOST_USER_PROTOCOL_F_MQ must be implemented. This may lead
implementors of vhost-user masters to believe that this protocol feature
is required for any device that has multiple virtqueues. That would be
a mistake since existing vhost-user slaves offer multiple virtqueues but
do not advertise VHOST_USER_PROTOCOL_F_MQ.
For example, a vhost-net device with one rx/tx queue pair is not
multiqueue. The slave does not need to advertise
VHOST_USER_PROTOCOL_F_MQ. Therefore the master must assume it has these
virtqueues and cannot rely on askingt the slave how many virtqueues
exist.
Extend the specification to explain the different between true
multiqueue and regular devices with a fixed virtqueue layout.

block: Only the main loop can change AioContexts
bdrv_set_aio_context_ignore() can only work in the main loop:
bdrv_drained_begin() only works in the main loop and the node's (old)
AioContext; and bdrv_drained_end() really only works in the main loop
and the node's (new) AioContext (contrary to its current comment, which
is just wrong).
Consequentially, bdrv_set_aio_context_ignore() must be called from the
main loop. Luckily, assuming that we can make block graph changes only
from the main loop as well, all its callers do that already.
Note that changing a node's context in a sense is an operation that
changes the block graph, so it actually makes sense to require this
function to be called from the main loop.
Also, fix bdrv_drained_end()'s description. You can only use it from
the main loop or the node's AioContext, and in the latter case, the
whole subtree must be in the same context.

block: Dec. drained_end_counter before bdrv_wakeup
Decrementing drained_end_counter after bdrv_dec_in_flight() (which in
turn invokes bdrv_wakeup() and thus aio_wait_kick()) is not very clever.
We should decrement it beforehand, so that any waiting aio_poll() that
is woken by bdrv_dec_in_flight() sees the decremented
drained_end_counter.
Because the time window between decrementing drained_end_counter and
aio_wait_kick() is very small, I cannot supply a reliable regression
test. However, running e.g. the /bdrv-drain/blockjob/iothread/drain_all
test in test-bdrv-drain has a small chance of hanging without this
patch (about 1/200 or so; it gets to nearly 100 % if you add e.g. an
fputc(' ', stderr); after the bdrv_dec_in_flight()).

target/arm: Limit ID register assertions to TCG
In arm_cpu_realizefn() we make several assertions about the values of
guest ID registers:
* if the CPU provides AArch32 v7VE or better it must advertise the
ARM_DIV feature
* if the CPU provides AArch32 A-profile v6 or better it must
advertise the Jazelle feature
These are essentially consistency checks that our ID register
specifications in cpu.c didn't accidentally miss out a feature,
because increasingly the TCG emulation gates features on the values
in ID registers rather than using old-style checks of ARM_FEATURE_FOO
bits.
Unfortunately, these asserts can cause problems if we're running KVM,
because in that case we don't control the values of the ID registers
-- we read them from the host kernel. In particular, if the host
kernel is older than 4.15 then it doesn't expose the ID registers via
the KVM_GET_ONE_REG ioctl, and we set up dummy values for some
registers and leave the rest at zero. (See the comment in
target/arm/kvm64.c kvm_arm_get_host_cpu_features().) This set of
dummy values is not sufficient to pass our assertions, and so on
those kernels running an AArch32 guest on AArch64 will assert.
We could provide a more sophisticated set of dummy ID registers in
this case, but that still leaves the possibility of a host CPU which
reports bogus ID register values that would cause us to assert. It's
more robust to only do these ID register checks if we're using TCG,
as that is the only case where this is truly a QEMU code bug.

nbd: Initialize reply on failure
We've had two separate reports of different callers running into use
of uninitialized data if s->quit is set (one detected by gcc -O3,
another by valgrind), due to checking 'nbd_reply_is_simple(reply) ||
s->quit' in the wrong order. Rather than chasing down which callers
need to pre-initialize reply, and whether there are any other
uninitialized uses, it's easier to guarantee that reply will always be
set by nbd_co_receive_one_chunk() even on failure.
The uninitialized use happens to be harmless (the only time the
variable is uninitialized is if s->quit is set, so the conditional
results in the same action regardless of what was read from reply),
and was introduced in commit
65e01d47.
In fixing the problem, it can also be seen that all (one) callers pass
in a non-NULL reply, so there is a dead conditional to also be cleaned
up.

hmp: Print if memory section is registered with an accelerator
This adds an accelerator name to the "into mtree -f" to tell the user if
a particular memory section is registered with the accelerator;
the primary user for this is KVM and such information is useful

This adds a has_memory() callback to the accelerator class allowing any

in accelerators (rather than memory regions), this only prints new labels

scsi-generic: Check sense key before request snooping and patching
When READ CAPACITY command completes, scsi_read_complete() function
snoops the command result and updates SCSIDevice members blocksize and
max_lba . However, this update is executed even when READ CAPACITY
command indicates an error in sense data. This causes unexpected
blocksize update with zero value for SCSI devices without
READ CAPACITY(10) command support and eventually results in a divide
by zero. An emulated device by TCMU-runner is an example of a device
that doesn't support READ CAPACITY(10) command.
To avoid the unexpected update, add sense key check in
scsi_read_complete() function. The function already checks the sense key
for VPD Block Limits emulation. Do the scsi_parse_sense_buf() call for
all requests rather than just for VPD Block Limits emulation, so that
blocksize and max_lba are only updated if READ CAPACITY returns zero
sense key.

target/i386: kvm: Demand nested migration kernel capabilities only when vCPU may have enabled VMX
Previous to this change, a vCPU exposed with VMX running on a kernel
without KVM_CAP_NESTED_STATE or KVM_CAP_EXCEPTION_PAYLOAD resulted in
adding a migration blocker. This was because when the code was written
it was thought there is no way to reliably know if a vCPU is utilising
VMX or not at runtime. However, it turns out that this can be known to
some extent:
In order for a vCPU to enter VMX operation it must have CR4.VMXE set.
Since it was set, CR4.VMXE must remain set as long as the vCPU is in
VMX operation. This is because CR4.VMXE is one of the bits set
in MSR_IA32_VMX_CR4_FIXED1.
There is one exception to the above statement when vCPU enters SMM mode.
When a vCPU enters SMM mode, it temporarily exits VMX operation and
may also reset CR4.VMXE during execution in SMM mode.
When the vCPU exits SMM mode, vCPU state is restored to be in VMX operation
and CR4.VMXE is restored to its original state of being set.
Therefore, when the vCPU is not in SMM mode, we can infer whether
VMX is being used by examining CR4.VMXE. Otherwise, we cannot
know for certain but assume the worse that vCPU may utilise VMX.
Summaring all the above, a vCPU may have enabled VMX in case
CR4.VMXE is set or vCPU is in SMM mode.
Therefore, remove migration blocker and check before migration
(cpu_pre_save()) if the vCPU may have enabled VMX. If true, only then
require relevant kernel capabilities.
While at it, demand KVM_CAP_EXCEPTION_PAYLOAD only when the vCPU is in
guest-mode and there is a pending/injected exception. Otherwise, this
kernel capability is not required for proper migration.

doc: document that the monitor console is a privileged control interface
A supposed exploit of QEMU was recently announced as CVE-2019-12928
claiming that the monitor console was insecure because the "migrate"
command enabled arbitrary command execution for a remote attacker.
To be a security risk the user launching QEMU must have configured
the monitor in a way that allows for other users to access it. The
exploit report quoted use of the "tcp" character device backend for
QMP.
This would indeed allow any network user to connect to QEMU and
execute arbitrary commands, however, this is not a flaw in QEMU.
It is the normal expected behaviour of the monitor console and the
commands it supports. Given a monitor connection, there are many
ways to access host file system content besides the migrate command.
The reality is that the monitor console (whether QMP or HMP) is
considered a privileged interface to QEMU and as such must only
be made available to trusted users. IOW, making it available with
no authentication over TCP is simply a, very serious, user
configuration error not a security flaw in QEMU itself.
The one thing this bogus security report highlights though is that
we have not clearly documented the security implications around the
use of the monitor. Add a few paragraphs of text to the security
docs explaining why the monitor is a privileged interface and making
a recommendation to only use the UNIX socket character device backend.
