tests/qtest/cmsdk-apb-watchdog-test: Parameterize tests
Currently the CMSDK APB watchdog tests target an specialized version
of the device (luminaris using the lm3s811evb machine) that prevents
the development of tests for the more generic device documented in:
https://developer.arm.com/documentation/ddi0479/d/apb-components/apb-watchdog/programmers-model
This patch allows the execution of the watchdog tests in an MPS2
machine (when applicable) which uses the generic version of the CMSDK
APB watchdog.
Finally the rules for compiling the test have to change because it is
possible not to have CONFIG_STELLARIS (required for the lm3s811evb
machine) while still having CONFIG_CMSDK_APB_WATCHDOG and the test
will fail. Due to the addition of the MPS2 machine CONFIG_MPS2
becomes also a dependency for the test compilation.

hw/watchdog/cmsdk_apb_watchdog: Fix INTEN issues
Current watchdog is free running out of reset, this combined with the
fact that current implementation also ensures the counter is running
when programing WDOGLOAD creates issues when the firmware defer the

Programmer's Model documentation states that INTEN is also the
counter enable:

hw/intc/openpic: Avoid taking address of out-of-bounds array index
The clang sanitizer complains about the code in the EOI handling
of openpic_cpu_write_internal():

SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior ../../hw/intc/openpic.c:1034:16 in
This is because we do
src = &opp->src[n_IRQ];
when n_IRQ may be -1. This is in practice harmless because if n_IRQ
is -1 then we don't do anything with the src pointer, but it is
undefined behaviour. (This has been present since this device
was first added to QEMU.)
Rearrange the code so we only do the array index when n_IRQ is not -1.

.gitlab-ci.d: Raise timeout on cross-accel build jobs to 60m
The current 30 minute timeout on the cross_accel_build_job template
is a bit low: sometimes if the k8s runners are running slow the
can hit it, for example this cross-arm64-xen-only job hit the
30 minute timeout while still not quite finished with the compile:
https://gitlab.com/qemu-project/qemu/-/jobs/
8401277985
This is partly a "runner performance can be unpredictable" issue:
https://gitlab.com/qemu-project/qemu/-/jobs/
8391726482
is the same job from just a day earlier and it finished in
16 minutes. But we already have build jobs that are higher
timeouts than 30 minutes, so we have headroom to raise the
timeout here to something we're less likely to hit on a slow
runner.
Bump the cross_accel_build_job timeout to 60 mins.

hw: Add "loadparm" property to scsi disk devices for booting on s390x
While adding the new flexible boot order feature on s390x recently,
we missed to add the "loadparm" property to the scsi-hd and scsi-cd
devices. This property is required on s390x to pass the information
to the boot loader about which kernel should be started or whether
the boot menu should be shown. But even more serious: The missing
property is now causing trouble with the corresponding libvirt patches
that assume that the "loadparm" property is either settable for all
bootable devices (when the "boot order" feature is implemented in
QEMU), or none (meaning the behaviour of older QEMUs that only allowed
one "loadparm" at the machine level). To fix this broken situation,
let's implement the "loadparm" property in for the SCSI devices, too.

nbd-server: Silence server warnings on port probes
While testing the use of qemu-nbd in a Pod of a Kubernetes cluster, I
got LOTS of log messages of the forms:
qemu-nbd: option negotiation failed: Failed to read flags: Unexpected end-of-file before all data were read
qemu-nbd: option negotiation failed: Failed to read flags: Unable to read from socket: Connection reset by peer
While it is nice to warn about clients that aren't following protocol
(in case it helps diagnosing bugs in those clients), a mere port probe
(where the client never write()s any bytes, and where we might even
hit EPIPE in trying to send our greeting to the client) is NOT
abnormal, but merely serves to pollute the log. And Kubernetes
_really_ likes to do port probes to determine whether a given Pod is
up and running.
Easy ways to demonstrate the above port probes:
$ qemu-nbd -r -f raw path/to/file &
$ nc localhost 10809 </dev/null
$ bash -c 'exec </dev/tcp/localhost/10809'
$ kill $!
Silence the noise by not capturing errors until after our first
successful read() from a client.

Fix this by marking the ip_header struct as QEMU_PACKED, so that
the compiler knows that it might be unaligned and will generate
the right code for accessing fields.

hw/net/virtio-net.c: Don't assume IP length field is aligned
In virtio-net.c we assume that the IP length field in the packet is
aligned, and we copy its address into a uint16_t* in the
VirtioNetRscUnit struct which we then dereference later. This isn't
a safe assumption; it will also result in compilation failures if we
mark the ip_header struct as QEMU_PACKED because the compiler will
not let you take the address of an unaligned struct field.
Make the ip_plen field in VirtioNetRscUnit a void*, and make all the
places where we read or write through that pointer instead use some
new accessor functions read_unit_ip_len() and write_unit_ip_len()
which account for the pointer being potentially unaligned and also do
the network-byte-order conversion we were previously using htons() to
perform.

hw/audio/hda: fix memory leak on audio setup
When SET_STREAM_FORMAT is called, the st->buft timer is overwritten, thus
causing a memory leak. This was originally fixed in commit
816139ae6a5
("hw/audio/hda: fix memory leak on audio setup", 2024-11-14) but that
caused the audio to break in SPICE.
Fortunately, a simpler fix is possible. The timer only needs to be
reset, because the callback is always the same (st->output is set at
realize time in hda_audio_init); call to timer_new_ns overkill. Replace
it with timer_del and only initialize the timer once; for simplicity,
do it even if use_timer is false.
An even simpler fix would be to free the old time in hda_audio_setup().
However, it seems better to place the initialization of the timer close
to that of st->ouput.

hw/misc/mos6522: Fix bad class definition of the MOS6522 device
When compiling QEMU with --enable-cfi, the "q800" m68k machine
currently crashes very early, when the q800_machine_init() function
tries to wire the interrupts of the "via1" device.
This happens because TYPE_MOS6522_Q800_VIA1 is supposed to be a
proper SysBus device, but its parent (TYPE_MOS6522) has a mistake
in its class definition where it is only derived from DeviceClass,
and not from SysBusDeviceClass, so we end up in funny memory access
issues here. Using the right class hierarchy for the MOS6522 device
fixes the problem.

tcg: Allow top bit of SIMD_DATA_BITS to be set in simd_desc()
In simd_desc() we create a SIMD descriptor from various pieces
including an arbitrary data value from the caller. We try to
sanitize these to make sure everything will fit: the 'data' value
needs to fit in the SIMD_DATA_BITS (== 22) sized field. However we
do that sanitizing with:
tcg_debug_assert(data == sextract32(data, 0, SIMD_DATA_BITS));
This works for the case where the data is supposed to be considered
as a signed integer (which can then be returned via simd_data()).
However, some callers want to treat the data value as unsigned.
Specifically, for the Arm SVE operations, make_svemte_desc()
assembles a data value as a collection of fields, and it needs to use
all 22 bits. Currently if MTE is enabled then its MTEDESC SIZEM1
field may have the most significant bit set, and then it will trip
this assertion.
Loosen the assertion so that we only check that the data value will
fit into the field in some way, either as a signed or as an unsigned
value. This means we will fail to detect some kinds of bug in the
callers, but we won't spuriously assert for intentional use of the
data field as unsigned.

target/i386: fix hang when using slow path for ptw_setl
When instrumenting memory accesses for plugin, we force memory accesses
to use the slow path for mmu [1]. This create a situation where we end
up calling ptw_setl_slow. This was fixed recently in [2] but the issue
still could appear out of plugins use case.
Since this function gets called during a cpu_exec, start_exclusive then
hangs. This exclusive section was introduced initially for security
reasons [3].
I suspect this code path was never triggered, because ptw_setl_slow
would always be called transitively from cpu_exec, resulting in a hang.

linux-user: Tolerate CONFIG_LSM_MMAP_MIN_ADDR
Running qemu-i386 on a system running with SELinux in enforcing mode
(more precisely: s390x trixie container on Fedora 40) fails with:
qemu-i386: tests/tcg/i386-linux-user/sigreturn-sigmask: Unable to find a guest_base to satisfy all guest address mapping requirements
00000000-
ffffffff
The reason is that main() determines mmap_min_addr from
/proc/sys/vm/mmap_min_addr, but SELinux additionally defines
CONFIG_LSM_MMAP_MIN_ADDR, which is normally larger: 32K or 64K, but,
in general, can be anything. There is no portable way to query its
value: /boot/config, /proc/config and /proc/config.gz are distro- and
environment-specific.
Once the identity map fails, the magnitude of guest_base does not
matter, so fix by starting the search from 1M or 1G.

https://lore.kernel.org/r/
20241107114256.106831-1-gerben@altlinux.org
In this merge, the migration_is_idle() function was replaced with
migrate_is_running(). However, the null pointer check for `s` was
removed, leading to a dereference of `s` when using qemu-system-x86_64
-hda *.vdi.
When replacing migration_is_idle() with "!migration_is_running()", it was
overlooked that the idle helper also checks for current_migration being
available first. Sample stack dump:
migration_is_running
is_busy
migrate_add_blocker_modes
migrate_add_blocker_normal
vmdk_open
bdrv_open_driver
bdrv_open_common
bdrv_open_inherit

blk_new_open
blockdev_init
drive_new
drive_init_func
qemu_opts_foreach
configure_blockdev
qemu_create_early_backends
qemu_init
main
The check would be there if the whole series was applied, but since the
last patches in the previous series rely on some other patches to land
first, we need to recover the behavior of migration_is_idle() first before
that whole set will be merged.
I left migration_is_active / migration_is_device alone, as I don't think
it's possible for them to hit uninitialized current_migration. Also they're
prone to removal soon from VFIO side.

hw/i386/pc: Don't try to init PCI NICs if there is no PCI bus
The 'isapc' machine type has no PCI bus, but pc_nic_init() still
calls pci_init_nic_devices() passing it a NULL bus pointer. This
causes the clang sanitizer to complain:
$ ./build/clang/qemu-system-i386 -M isapc
../../hw/pci/pci.c:1866:39: runtime error: member access within null pointer of type 'PCIBus' (aka 'struct PCIBus')
SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior ../../hw/pci/pci.c:1866:39 in
This is because pci_init_nic_devices() does
&bus->qbus
which is undefined behaviour on a NULL pointer even though we're not
actually dereferencing the pointer. (We don't actually crash as
a result, so if you aren't running a sanitizer build then there
are no user-visible effects.)
Make pc_nic_init() avoid trying to initialize PCI NICs on a non-PCI
system.

The handling for CPUID function 0xD (supported XSAVE features) was
improved in a recent patch. Unfortunately, this appears to have
introduced undefined behaviour for cases where ecx > 30, as the result
of (1 << idx) is undefined if idx > 30.
Per Intel SDM section 13.2, the behaviour for ecx values up to and
including 62 are specified. This change therefore specifically sets
all registers returned by the CPUID instruction to 0 for 63 and higher.
Furthermore, the bit shift uses uint64_t, where behaviour for the entire
range of 2..62 is safe and correct.

i386/hvf: Integrates x2APIC support with hvf accel
Support for x2APIC mode was recently introduced in the software emulated
APIC implementation for TCG. Enabling it when using macOS’s hvf
accelerator is useful and significantly helps performance, as Qemu
currently uses the emulated APIC when running on hvf as well.
This change wires up the read & write operations for the MSR VM exits

9pfs: fix crash on 'Treaddir' request
A bad (broken or malicious) 9p client (guest) could cause QEMU host to
crash by sending a 9p 'Treaddir' request with a numeric file ID (FID) that
was previously opened for a file instead of an expected directory:
#0 0x0000762aff8f4919 in __GI___rewinddir (dirp=0xf) at
../sysdeps/unix/sysv/linux/rewinddir.c:29
#1 0x0000557b7625fb40 in do_readdir_many (pdu=0x557bb67d2eb0,
fidp=0x557bb67955b0, entries=0x762afe9fff58, offset=0, maxsize=131072,
dostat=<optimized out>) at ../hw/9pfs/codir.c:101
#2 v9fs_co_readdir_many (pdu=pdu@entry=0x557bb67d2eb0,
fidp=fidp@entry=0x557bb67955b0, entries=entries@entry=0x762afe9fff58,
offset=0, maxsize=131072, dostat=false) at ../hw/9pfs/codir.c:226
#3 0x0000557b7625c1f9 in v9fs_do_readdir (pdu=0x557bb67d2eb0,
fidp=0x557bb67955b0, offset=<optimized out>,

#4 v9fs_readdir (opaque=0x557bb67d2eb0) at ../hw/9pfs/9p.c:2602
That's because V9fsFidOpenState was declared as union type. So the
same memory region is used for either an open POSIX file handle (int),
or a POSIX DIR* pointer, etc., so 9p server incorrectly used the
previously opened (valid) POSIX file handle (0xf) as DIR* pointer,
eventually causing a crash in glibc's rewinddir() function.
Root cause was therefore a missing check in 9p server's 'Treaddir'
request handler, which must ensure that the client supplied FID was
really opened as directory stream before trying to access the
aforementioned union and its DIR* member.

hw/nvme: fix handling of over-committed queues
If a host chooses to use the SQHD "hint" in the CQE to know if there is
room in the submission queue for additional commands, it may result in a
situation where there are not enough internal resources (struct
NvmeRequest) available to process the command. For a lack of a better
term, the host may "over-commit" the device (i.e., it may have more
inflight commands than the queue size).
For example, assume a queue with N entries. The host submits N commands
and all are picked up for processing, advancing the head and emptying
the queue. Regardless of which of these N commands complete first, the
SQHD field of that CQE will indicate to the host that the queue is
empty, which allows the host to issue N commands again. However, if the
device has not posted CQEs for all the previous commands yet, the device
will have less than N resources available to process the commands, so
queue processing is suspended.
And here lies an 11 year latent bug. In the absense of any additional
tail updates on the submission queue, we never schedule the processing
bottom-half again unless we observe a head update on an associated full
completion queue. This has been sufficient to handle N-to-1 SQ/CQ setups
(in the absense of over-commit of course). Incidentially, that "kick all
associated SQs" mechanism can now be killed since we now just schedule
queue processing when we return a processing resource to a non-empty
submission queue, which happens to cover both edge cases. However, we
must retain kicking the CQ if it was previously full.
So, apparently, no previous driver tested with hw/nvme has ever used
SQHD (e.g., neither the Linux NVMe driver or SPDK uses it). But then OSv
shows up with the driver that actually does. I salute you.

target/i386: Fix legacy page table walk
Commit
b56617bbcb4 ("target/i386: Walk NPT in guest real mode") added
logic to run the page table walker even in real mode if we are in NPT
mode. That function then determined whether real mode or paging is
active based on whether the pg_mode variable was 0.
Unfortunately pg_mode is 0 in two situations:
1) Paging is disabled (real mode)
2) Paging is in 2-level paging mode (32bit without PAE)
That means the walker now assumed that 2-level paging mode was real
mode, breaking NetBSD as well as Windows XP.
To fix that, this patch adds a new PG flag to pg_mode which indicates
whether paging is active at all and uses that to determine whether we
are in real mode or not.
