The vcek-disabled property of the sev-snp-guest object is misspelled
vcek-required (which I suppose would use the opposite polarity) in
the call to object_class_property_add_bool().  Fix it.

The QIOChannelFile object already has its reference decremented by

…on fails

When a channel fails to create, the code currently just returns. This
is wrong for two reasons:

1) Channel n+1 will not get to initialize it's semaphores, leading to
   an assert when terminate_threads tries to post to it:

 qemu-system-x86_64: ../util/qemu-thread-posix.c:92:
 qemu_mutex_lock_impl: Assertion `mutex->initialized' failed.

2) (theoretical) If channel n-1 already started creation it will
   defeat the purpose of the channels_created logic which is in place
   to avoid migrate_fd_cleanup() to run while channels are still being
   created.

   This cannot really happen today because the current failure cases
   for multifd_new_send_channel_create() are all synchronous,
   resulting from qio_channel_file_new_path() getting a bad
   filename. This would hit all channels equally.

   But I don't want to set a trap for future people, so have all
   channels try to create (even if failing), and only fail after the
   channels_created semaphore has been posted.

While here, remove the error_report_err call. There's one already at
migrate_fd_cleanup later on.

The reason is that all pr_pid values are the same, because the same
TaskState is used for all CPUs when generating NT_PRSTATUS notes.

Fix by using TaskStates associated with individual CPUs.

Allow overlapping request by removing the assert that made it
impossible. There are only two callers:

1. block_copy_task_create()

It already asserts the very same condition before calling
reqlist_init_req().

2. cbw_snapshot_read_lock()

There is no need to have read requests be non-overlapping in
copy-before-write when used for snapshot-access. In fact, there was no
protection against two callers of cbw_snapshot_read_lock() calling
reqlist_init_req() with overlapping ranges and this could lead to an
assertion failure [1].

In particular, with the reproducer script below [0], two
cbw_co_snapshot_block_status() callers could race, with the second
calling reqlist_init_req() before the first one finishes and removes
its conflicting request.

target_ulong is typedef'ed as a 32-bit integer when building the
qemu-system-arm target, and this is smaller than the size of an
intermediate physical address when LPAE is being used.

Given that Linux may place leaf level user page tables in high memory
when built for LPAE, the kernel will crash with an external abort as
soon as it enters user space when running with more than ~3 GiB of
system RAM.

So replace target_ulong with vaddr in places where it may carry an
address value that is not representable in 32 bits.

Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>
The enable bits in the EXT_CSD_PART_CONFIG ext_csd register do *not*
specify whether the boot partitions exist, but whether they are enabled
for booting. Existence of the boot partitions is specified by a
EXT_CSD_BOOT_MULT != 0.

Currently, in the case of boot-partition-size=1M and boot-config=0,
Linux detects boot partitions of 1M. But as sd_bootpart_offset always
returns 0, all reads/writes are mapped to the same offset in the backing
file.

Fix this bug by calculating the offset independent of which partition is
enabled for booting.

This bug is unlikely to affect many users with QEMU's current set of
boards, because only aspeed sets boot-partition-size, and it also
sets boot-config to 8. So to run into this a user would have to
manually mark the boot partition non-booting from within the guest.

The mips64el cross setup is very broken for bullseye which has now
entered LTS support so is unlikely to be fixed. While we still can't
build the container with all packages for bookworm due to a single
missing dependency that will hopefully get fixed in due course. For
the sake of keeping the CI green we disable the problematic packages

In commit b88cfee we defined masks for the IBRD and FBRD
integer and fractional baud rate divider registers, to prevent the
guest from writing invalid values which could cause division-by-zero.
Unfortunately we got the mask values the wrong way around: the FBRD
register is six bits and the IBRD register is 16 bits, not
vice-versa.

You would only run into this bug if you programmed the UART to a baud
rate of less than 9600, because for 9600 baud and above the IBRD
value will fit into 6 bits, as per the table in
 https://developer.arm.com/documentation/ddi0183/g/programmers-model/register-descriptions/fractional-baud-rate-register--uartfbrd

The only visible effects would be that the value read back from
the register by the guest would be truncated, and we would
print an incorrect baud rate in the debug logs.

A filter function that wants to drop a message should return NULL, in
which case it must also unref the message itself.

Fixes: fa88b85 ("ui/dbus: filter out pending messages when scanout")

(cherry picked from commit 244d52f)

DisplaySurface may be free before the pixman image is freed, since the
image is refcounted and used by different objects, including pending
dbus messages.

Furthermore, setting the destroy function in
create_displaysurface_from() isn't appropriate, as it may not be used,
and may be overriden as in ramfb.

Set the destroy function when the shared handle is set, use the HANDLE
directly for destroy data, using a single common helper
qemu_pixman_win32_image_destroy().

(cherry picked from commit 330ef31)
Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>
Filtering pending messages when a new scanout is given shouldn't discard
pending cursor changes, for example.

Since filtering happens in a different thread, use atomic set/get.
