icount: Take iothread lock when running QEMU timers
The function icount_prepare_for_run() is called with the iothread
unlocked, but it can call icount_notify_aio_contexts() which will
run qemu timer handlers. Those are supposed to be run only with
the iothread lock held, so take the lock while we do that.
Since icount mode runs everything on a single thread anyway,
not holding the lock is likely mostly not going to introduce
races, but it can cause us to trip over assertions that we
do hold the lock, such as the one reported in issue 1130.

hw/net/rocker: Avoid undefined shifts with more than 31 ports
In rocker_port_phys_link_status() and rocker_port_phys_enable_read()
we construct a 64-bit value with one bit per front-panel port.
However we accidentally do the shift as 32-bit arithmetic, which
means that if there are more than 31 front-panel ports this is
undefined behaviour.
Fix the problem by ensuring we use 64-bit arithmetic for the whole
calculation. (We won't ever shift off the 64-bit value because
ROCKER_FP_PORTS_MAX is 62.)

with byte and halfword reads as well as word reads. Our
implementation currently only handles word reads. Add support for
the 8 and 16 bit accesses. Note that we only need to handle aligned
accesses -- unaligned accesses should continue to trap, as happens on

QEMU crashes trying to save VMSTATE when only MIPS target are compiled in

Segmentation fault (core dumped)
It happens due to PIIX4_PM trying to parse hotplug vmstate structures
which are valid only for x86 and not for MIPS (as it requires ACPI
tables support which is not existent for ithe later)
Issue was probably exposed by trying to cleanup/compile out unused

vl: fix [memory] section with -readconfig
The -M memory.* options do not have magic applied to them like the -m
option, namely no "M" (for mebibytes) is tacked at the end of a suffixless
value for "-M memory.size".
This magic is performed by parse_memory_options, and we have to do it for
both "-m" and the [memory] section of a config file. Storing [memory]
sections directly to machine_opts_dict changed the meaning of
[memory]
size = "1024"
in a -readconfig file from 1024MiB to 8KiB (1024 Bytes rounded up to
8KiB silently). To avoid this, the [memory] section has to be changed
back to QemuOpts (combining [memory] and "-m" will work fine thanks to
.merge_lists being true).
Change parse_memory_options() so that, similar to the older function
set_memory_options(), it operates after command line parsing is done;
and also call it where set_memory_options() used to be.
Note, the parsing code uses exit(1) instead of exit(EXIT_FAILURE) to
match neighboring code.

pc-bios/s390-ccw: Fix booting with logical block size < physical block size
For accessing single blocks during boot, it's the logical block size that
matters. (Physical block sizes are rather interesting e.g. for creating
file systems with the correct alignment for speed reasons etc.).
So the s390-ccw bios has to use the logical block size for calculating
sector numbers during the boot phase, the "physical_block_exp" shift
value must not be taken into account. This change fixes the boot process
when the guest hast been installed on a disk where the logical block size
differs from the physical one, e.g. if the guest has been installed
like this:
qemu-system-s390x -nographic -accel kvm -m 2G \
-drive if=none,id=d1,file=fedora.iso,format=raw,media=cdrom \
-device virtio-scsi -device scsi-cd,drive=d1 \
-drive if=none,id=d2,file=test.qcow2,format=qcow2
-device virtio-blk,drive=d2,physical_block_size=4096,logical_block_size=512
Linux correctly uses the logical block size of 512 for the installation,
but the s390-ccw bios tries to boot from a disk with 4096 block size so
far, as long as this patch has not been applied yet (well, it used to work
by accident in the past due to the virtio_assume_scsi() hack that used to
enforce 512 byte sectors on all virtio-block disks, but that hack has been
well removed in commit
5447de2619050a0a4d to fix other scenarios).

util/qemu-sockets: Replace the call to close a socket with closesocket()
close() is a *nix function. It works on any file descriptor, and
sockets in *nix are an example of a file descriptor.
closesocket() is a Windows-specific function, which works only
specifically with sockets. Sockets on Windows do not use *nix-style
file descriptors, and socket() returns a handle to a kernel object
instead, so it must be closed with closesocket().
In QEMU there is already a logic to handle such platform difference
in os-posix.h and os-win32.h, that:
* closesocket maps to close on POSIX
* closesocket maps to a wrapper that calls the real closesocket()
on Windows
Replace the call to close a socket with closesocket() instead.

QIOChannelSocket: Add support for MSG_ZEROCOPY + IPV6
For using MSG_ZEROCOPY, there are two steps:
1 - io_writev() the packet, which enqueues the packet for sending, and
2 - io_flush(), which gets confirmation that all packets got correctly sent
Currently, if MSG_ZEROCOPY is used to send packets over IPV6, no error will
be reported in (1), but it will fail in the first time (2) happens.
This happens because (2) currently checks for cmsg_level & cmsg_type
associated with IPV4 only, before reporting any error.
Add checks for cmsg_level & cmsg_type associated with IPV6, and thus enable
support for MSG_ZEROCOPY + IPV6

mal->irqs[i] = irqs[i];
}
Since only irqs[0] has been initialized, mal->irqs[1,2,3] are being
zeroed.
This doesn´t seem to trigger any apparent issues at this moment, but
Cedric's QOMification of the MAL device [1] is executing a
sysbus_connect_irq() that will fail if we do not store all GPIO lines
properly.

We currently require at least GCC 7.4 or Clang 6.0 for compiling QEMU.
GCC has __builtin_mul_overflow since version 5 already, and Clang 6.0
also provides this built-in function (see its documentation on this page:

virtiofsd: Disable killpriv_v2 by default
We are having bunch of issues with killpriv_v2 enabled by default. First
of all it relies on clearing suid/sgid bits as needed by dropping
capability CAP_FSETID. This does not work for remote filesystems like
NFS (and possibly others).
Secondly, we are noticing other issues related to clearing of SGID
which leads to failures for xfstests generic/355 and generic/193.
Thirdly, there are other issues w.r.t caching of metadata (suid/sgid)
bits in fuse client with killpriv_v2 enabled. Guest can cache that
data for sometime even if cleared on server.
Second and Third issue are fixable. Just that it might take a little
while to get it fixed in kernel. First one will probably not see
any movement for a long time.
Given these issues, killpriv_v2 does not seem to be a good candidate
for enabling by default. We have already disabled it by default in
rust version of virtiofsd.
Hence this patch disabled killpriv_v2 by default. User can choose to
enable it by passing option "-o killpriv_v2".

migration: Define BLK_MIG_BLOCK_SIZE as unsigned long long
When we use BLK_MIG_BLOCK_SIZE in expressions like
block_mig_state.submitted * BLK_MIG_BLOCK_SIZE, this multiplication
is done as 32 bits, because both operands are 32 bits. Coverity
complains about possible overflows because we then accumulate that
into a 64 bit variable.
Define BLK_MIG_BLOCK_SIZE as unsigned long long using the ULL suffix.
The only two current uses of it with this problem are both in
block_save_pending(), so we could just cast to uint64_t there, but
using the ULL suffix is simpler and ensures that we don't
accidentally introduce new variants of the same issue in future.

migration: Assert that migrate_multifd_compression() returns an in-range value
Coverity complains that when we use the return value from
migrate_multifd_compression() as an array index:
multifd_recv_state->ops = multifd_ops[migrate_multifd_compression()];
that this might overrun the array (which is declared to have size
MULTIFD_COMPRESSION__MAX). This is because the function return type
is MultiFDCompression, which is an autogenerated enum. The code
generator includes the "one greater than the maximum possible value"
MULTIFD_COMPRESSION__MAX in the enum, even though this is not
actually a valid value for the enum, and this makes Coverity think
that migrate_multifd_compression() could return that __MAX value and
index off the end of the array.
Suppress the Coverity error by asserting that the value we're going
to return is within range.

This reverts commit
cfd66f30fb0f735df06ff4220e5000290a43dad3.
The simplification of unqueue_page() introduced a bug that sometimes
breaks migration on s390x hosts.
The problem is not fully understood yet, but since we are already in
the freeze for QEMU 7.1 and we need something working there, let's
revert this patch for the upcoming release. The optimization can be
redone later again in a proper way if necessary.

hw/block/hd-geometry: Do not override specified bios-chs-trans
For small disk images (<4 GiB), QEMU and SeaBIOS default to the
LARGE/ECHS disk translation method, but it is not uncommon for other
BIOS software to use LBA in these cases as well. Some operating
system boot loaders (e.g., NT 4) do not handle LARGE translations
outside of fixed configurations. See, e.g., Q154052:
"When starting an x86 based computer, Ntdetect.com retrieves and
stores Interrupt 13 information. . . If the disk controller is using a
32 sector/64 head translation scheme, this boundary will be 1 GB. If
the controller uses 63 sector/255 head translation [AUTHOR: i.e.,
LBA], the limit will be 4 GB."
To accommodate these situations, hd_geometry_guess() now follows the
disk translation specified by the user even when the ATA disk geometry
is guessed.
hd_geometry_guess():
* Only set the disk translation when translation is AUTO.
* Show the soon-to-be active translation (*ptrans) in the trace rather
than what was guessed.

Coverity reported a string overflow issue since we copied
"name" to "dev_config->name" without checking the length.
This should be a false positive since we already checked
the length of "name" in vduse_name_is_invalid(). But anyway,
let's replace strcpy() with strncpy() (as a general library,
we'd like to minimize dependencies on other libraries, so we
didn't use g_strlcpy() here) to fix the coverity complaint.

tests/qtest/migration-test: Run the dirty ring tests only with the x86 target
kvm_dirty_ring_supported() only checks whether the dirty ring support
is available on the x86 host, but it ignores whether the target QEMU
architecture is x86 or not. Thus the test_vcpu_dirty_limit() test
currently fails with the assert((strcmp(arch, "x86_64") == 0)) statement
in dirtylimit_start_vm() if the users run e.g. "make check-qtest-aarch64"

aspeed/fby35: Fix owner of the BMC RAM memory region
A MachineState object is used as a owner of the RAM region and this
asserts in memory_region_init_ram() when QEMU is built with
CONFIG_QOM_CAST_DEBUG :
/* This will assert if owner is neither NULL nor a DeviceState.
* We only want the owner here for the purposes of defining a
* unique name for migration. TODO: Ideally we should implement
* a naming scheme for Objects which are not DeviceStates, in
* which case we can relax this restriction.
*/

Use the BMC and BIC objects as the owners of their memory regions.

scsi-disk: ensure block size is non-zero and changes limited to bits 8-15
The existing code assumes that the block size can be generated from p[1] << 8
in multiple places which ignores the top and bottom 8 bits. If the block size
is allowed to be set to an arbitrary value then this causes a mismatch
between the value written by the guest in the block descriptor and the value
subsequently read back using READ CAPACITY causing the guest to generate
requests that can crash QEMU.
For now restrict block size changes to bits 8-15 and also ignore requests to
set the block size to 0 which causes the SCSI emulation to crash in at least
one place with a divide by zero error.

scsi-disk: fix overflow when block size is not a multiple of BDRV_SECTOR_SIZE
In scsi_disk_emulate_write_same() the number of host sectors to transfer is
calculated as (s->qdev.blocksize / BDRV_SECTOR_SIZE) which is then used to
copy data in block size chunks to the iov buffer.
Since the loop copying the data to the iov buffer uses a fixed increment of
s->qdev.blocksize then using a block size that isn't a multiple of
BDRV_SECTOR_SIZE introduces a rounding error in the iov buffer size calculation
such that the iov buffer copy overflows the space allocated.
Update the iov buffer copy for() loop so that it will use the smallest of either
the current block size or the remaining transfer count to prevent the overflow.
