Subject: Disable unwanted new devices
|
|
||||||
|
|
||||||
QEMU 8.0 adds two new device we do not want to support that can't
|
|
||||||
be disabled using configure switch.
|
|
||||||
|
|
||||||
1) ide-cf - virtual CompactFlash card
|
|
||||||
|
|
||||||
2) i2c-echo - testing echo device
|
|
||||||
|
|
||||||
Use manual disabling of the device by changing code (1) and meson configs (2).

RH-Commit: [2/3] 1cb3d72b86ced0f70a09dfa0d325ae8a85db1b2b (berrange/centos-src-qemu)
|
||||||
|
|
||||||
|
This commit results in unexpected termination of the TLS connection.
|
||||||
|
When 'fd_can_read' returns 0, the code goes on to pass a zero length
|
||||||
|
buffer to qio_channel_read. The TLS impl calls into gnutls_recv()
|
||||||
|
with this zero length buffer, at which point GNUTLS returns an error
|
||||||
|
GNUTLS_E_INVALID_REQUEST. This is treated as fatal by QEMU's TLS code
|
||||||
|
resulting in the connection being torn down by the chardev.
|
||||||
|
|
||||||
|
Simply skipping the qio_channel_read when the buffer length is zero
|
||||||
|
is also not satisfactory, as it results in a high CPU burn busy loop
|
||||||
|
massively slowing QEMU's functionality.
|
||||||
|
|
||||||
|
The proper solution is to avoid tcp_chr_read being called at all
|
||||||
|
unless the frontend is able to accept more data. This will be done
|
||||||
|
in a followup commit.

||||||

|
||||||
|
|
||||||
|
This reverts commit a7077b8e354d90fec26c2921aa2dea85b90dff90,
|
||||||
|
and add comments to explain why child sources cannot be used.
|
||||||
|
|
||||||
|
When a GSource is added as a child of another GSource, if its
|
||||||
|
'prepare' function indicates readiness, then the parent's
|
||||||
|
'prepare' function will never be run. The io_watch_poll_prepare
|
||||||
|
absolutely *must* be run on every iteration of the main loop,
|
||||||
|
to ensure that the chardev backend doesn't feed data to the
|
||||||
|
frontend that it is unable to consume.
|
||||||
|
|
||||||
|
At the time a7077b8e354d90fec26c2921aa2dea85b90dff90 was made,
|
||||||
|
all the child GSource impls were relying on poll'ing an FD,
|
||||||
|
so their 'prepare' functions would never indicate readiness
|
||||||
|
ahead of poll() being invoked. So the buggy behaviour was
|
||||||
|
not noticed and lay dormant.
|
||||||
|
|
||||||
|
Relatively recently the QIOChannelTLS impl introduced a
|
||||||
|
level 2 child GSource, which checks with GNUTLS whether it
|
||||||
|
has cached any data that was decoded but not yet consumed:
|
||||||
|
|
||||||

|
io/channel-tls: fix handling of bigger read buffers
|
||||||
|
|
||||||
|
Since the TLS backend can read more data from the underlying QIOChannel
|
||||||
|
we introduce a minimal child GSource to notify if we still have more
|
||||||
|
data available to be read.

|

|
|
||||||
|
With this, it is now quite common for the 'prepare' function
|
||||||
|
on a QIOChannelTLS GSource to indicate immediate readiness,
|
||||||
|
bypassing the parent GSource 'prepare' function. IOW, the
|
||||||
|
critical 'io_watch_poll_prepare' is being skipped on some
|
||||||
|
iterations of the main loop. As a result chardev frontend
|
||||||
|
asserts are now being triggered as they are fed data they
|
||||||
|
are not ready to consume.
|
||||||
|
|
||||||
|
A reproducer is as follows:
|
||||||
|
|
||||||
|
* In terminal 1 run a GNUTLS *echo* server
|
||||||
|
|
||||||
|
$ gnutls-serv --echo \
|
||||||
|
--x509cafile ca-cert.pem \
|
||||||
|
--x509keyfile server-key.pem \
|
||||||
|
--x509certfile server-cert.pem \
|
||||||
|
-p 9000
|
||||||
|
|
||||||
|
* In terminal 2 run a QEMU guest
|
||||||
|
|
||||||
|
$ qemu-system-s390x \
|
||||||
|
-nodefaults \
|
||||||
|
-display none \
|
||||||
|
-object tls-creds-x509,id=tls0,dir=$PWD,endpoint=client \
|
||||||
|
-chardev socket,id=con0,host=localhost,port=9000,tls-creds=tls0 \
|
||||||
|
-device sclpconsole,chardev=con0 \
|
||||||
|
-hda Fedora-Cloud-Base-39-1.5.s390x.qcow2
|
||||||
|
|
||||||
|
After the previous patch revert, but before this patch revert,
|
||||||
|
this scenario will crash:
|
||||||
|
|
||||||
|
qemu-system-s390x: ../hw/char/sclpconsole.c:73: chr_read: Assertion
|
||||||
|
`size <= SIZE_BUFFER_VT220 - scon->iov_data_len' failed.
|
||||||
|
|
||||||
|
This assert indicates that 'tcp_chr_read' was called without
|
||||||
|
'tcp_chr_read_poll' having first been checked for ability to
|
||||||
|
receive more data
|
||||||
|
|
||||||
|
QEMU's use of a 'prepare' function to create/delete another
|
||||||
|
GSource is rather a hack and not normally the kind of thing that
|
||||||
|
is expected to be done by a GSource. There is no mechanism to
|
||||||
|
force GLib to always run the 'prepare' function of a parent
|
||||||
|
GSource. The best option is to simply not use the child source
|
||||||
|
concept, and go back to the functional approach previously
|
||||||
|
relied on.

RH-Commit: [1/1] 9c597232466b27d91f127ee6004322d6ba69755f (imammedo/qemu-kvm-c-9-s-imam)
|
|
||||||
|
|
||||||
with Q35 using ACPI PCI hotplug by default, user's request to unplug
|
|
||||||
device is ignored when it's issued before guest OS has been booted.
|
|
||||||
And any additional attempt to request device hot-unplug afterwards
|
|
||||||
results in following error:
|
|
||||||
|
|
||||||
"Device XYZ is already in the process of unplug"
|
|
||||||
|
|
||||||
arguably it can be considered as a regression introduced by [2],
|
|
||||||
before which it was possible to issue unplug request multiple
|
|
||||||
times.
|
|
||||||
|
|
||||||
Accept new uplug requests after timeout (1ms). This brings ACPI PCI
|
|
||||||
hotplug on par with native PCIe unplug behavior [1] and allows user
|
|
||||||
to repeat unplug requests at propper times.
|
|
||||||
Set expire timeout to arbitrary 1msec so user won't be able to
|
|
||||||
flood guest with SCI interrupts by calling device_del in tight loop.
|
|
||||||
|
|
||||||
PS:
|
|
||||||
ACPI spec doesn't mandate what OSPM can do with GPEx.status
|
|
||||||
bits set before it's booted => it's impl. depended.
|
|
||||||
Status bits may be retained (I tested with one Windows version)
|
|
||||||
or cleared (Linux since 2.6 kernel times) during guest's ACPI
|
|
||||||
subsystem initialization.
|
|
||||||
Clearing status bits (though not wrong per se) hides the unplug
|
|
||||||
event from guest, and it's upto user to repeat device_del later
|
|
||||||
when guest is able to handle unplug requests.
|
|
||||||
|
|
||||||
1) 18416c62e3 ("pcie: expire pending delete")
|
|
||||||
2)
|
|
||||||

RH-Commit: [15/26] 723dcada900aaf08862e8221921be22506b561a8 (kmwolf/centos-qemu-kvm)
|
||||||
|
|
||||||
|
aio_context_acquire()/aio_context_release() has been replaced by
|
||||||
|
fine-grained locking to protect state shared by multiple threads. The
|
||||||
|
AioContext lock still plays the role of balancing locking in
|
||||||
|
AIO_WAIT_WHILE() and many functions in QEMU either require that the
|
||||||
|
AioContext lock is held or not held for this reason. In other words, the
|
||||||
|
AioContext lock is purely there for consistency with itself and serves
|
||||||
|
no real purpose anymore.
|
||||||
|
|
||||||
|
Stop actually acquiring/releasing the lock in
|
||||||
|
aio_context_acquire()/aio_context_release() so that subsequent patches
|
||||||
|
can remove callers across the codebase incrementally.
|
||||||
|
|
||||||
|
I have performed "make check" and qemu-iotests stress tests across
|
||||||
|
x86-64, ppc64le, and aarch64 to confirm that there are no failures as a
|
||||||
|
result of eliminating the lock.

|
||||||
|
|
||||||
|
Delete these functions because nothing calls these functions anymore.
|
||||||
|
|
||||||
|
I introduced these APIs in commit 98563fc3ec44 ("aio: add
|
||||||
|
aio_context_acquire() and aio_context_release()") in 2014. It's with a
|
||||||
|
sigh of relief that I delete these APIs almost 10 years later.
|
||||||
|
|
||||||
|
Thanks to Paolo Bonzini's vision for multi-queue QEMU, we got an
|
||||||
|
understanding of where the code needed to go in order to remove the
|
||||||
|
limitations that the original dataplane and the IOThread/AioContext
|
||||||
|
approach that followed it.
|
||||||
|
|
||||||
|
Emanuele Giuseppe Esposito had the splendid determination to convert
|
||||||
|
large parts of the codebase so that they no longer needed the AioContext
|
||||||
|
lock. This was a painstaking process, both in the actual code changes
|
||||||
|
required and the iterations of code review that Emanuele eked out of
|
||||||
|
Kevin and me over many months.
|
||||||
|
|
||||||
|
Kevin Wolf tackled multitudes of graph locking conversions to protect
|
||||||
|
in-flight I/O from run-time changes to the block graph as well as the
|
||||||
|
clang Thread Safety Analysis annotations that allow the compiler to
|
||||||
|
check whether the graph lock is being used correctly.
|
||||||
|
|
||||||
|
And me, well, I'm just here to add some pizzazz to the QEMU multi-queue
|
||||||
|
block layer :). Thank you to everyone who helped with this effort,
|
||||||
|
including Eric Blake, code reviewer extraordinaire, and others who I've
|
||||||
|
forgotten to mention.

RH-Commit: [20/26] 20e49777869714c99769263103f1b0c2c370cfcd (kmwolf/centos-qemu-kvm)
|
||||||
|
|
||||||
|
Now that the AioContext lock no longer exists, AIO_WAIT_WHILE() and
|
||||||
|
AIO_WAIT_WHILE_UNLOCKED() are equivalent.
|
||||||
|
|
||||||
|
A future patch will get rid of AIO_WAIT_WHILE_UNLOCKED().

async: Add an optional reentrancy guard to the BH API
|
|
||||||
|
|
||||||
Devices can pass their MemoryReentrancyGuard (from their DeviceState),
|
|
||||||
when creating new BHes. Then, the async API will toggle the guard
|
|
||||||
before/after calling the BH call-back. This prevents bh->mmio reentrancy
|
|
||||||
issues.

async: avoid use-after-free on re-entrancy guard
|
|
||||||
|
|
||||||
A BH callback can free the BH, causing a use-after-free in aio_bh_call.
|
|
||||||
Fix that by keeping a local copy of the re-entrancy guard pointer.

RH-Commit: [20/67] 8a56344ab4a2126f248bfa492ccddd19265f39be (eauger1/centos-qemu-kvm)
|
||||||
|
|
||||||
|
Introduce an iommufd object which allows the interaction
|
||||||
|
with the host /dev/iommu device.
|
||||||
|
|
||||||
|
The /dev/iommu can have been already pre-opened outside of qemu,
|
||||||
|
in which case the fd can be passed directly along with the
|
||||||
|
iommufd object:
|
||||||
|
|
||||||
|
This allows the iommufd object to be shared accross several
|
||||||
|
subsystems (VFIO, VDPA, ...). For example, libvirt would open
|
||||||
|
the /dev/iommu once.
|
||||||
|
|
||||||
|
If no fd is passed along with the iommufd object, the /dev/iommu
|
||||||
|
is opened by the qemu code.

|
||||||
|
|
||||||
|
Coverity reports a concurrent data access violation because be->users
|
||||||
|
is being accessed in iommufd_backend_can_be_deleted() without holding
|
||||||
|
the mutex.
|
||||||
|
|
||||||
|
However, these routines are called from the QEMU main thread when a
|
||||||
|
device is created. In this case, the code paths should be protected by
|
||||||
|
the BQL lock and it should be safe to drop the IOMMUFD backend mutex.
|
||||||
|
Simply remove it.

|
|
||||||
|
|
||||||
When processing vectored guest requests that are not aligned to the
|
|
||||||
storage request alignment, we pad them by adding head and/or tail
|
|
||||||
buffers for a read-modify-write cycle.
|
|
||||||
|
|
||||||
The guest can submit I/O vectors up to IOV_MAX (1024) in length, but
|
|
||||||
with this padding, the vector can exceed that limit. As of
|
|
||||||
4c002cef0e9abe7135d7916c51abce47f7fc1ee2 ("util/iov: make
|
|
||||||
qemu_iovec_init_extended() honest"), we refuse to pad vectors beyond the
|
|
||||||
limit, instead returning an error to the guest.
|
|
||||||
|
|
||||||
To the guest, this appears as a random I/O error. We should not return
|
|
||||||
an I/O error to the guest when it issued a perfectly valid request.
|
|
||||||
|
|
||||||
Before 4c002cef0e9abe7135d7916c51abce47f7fc1ee2, we just made the vector
|
|
||||||
longer than IOV_MAX, which generally seems to work (because the guest
|
|
||||||
assumes a smaller alignment than we really have, file-posix's
|
|
||||||
raw_co_prw() will generally see bdrv_qiov_is_aligned() return false, and
|
|
||||||
so emulate the request, so that the IOV_MAX does not matter). However,
|
|
||||||
that does not seem exactly great.
|
|
||||||
|
|
||||||
I see two ways to fix this problem:
|
|
||||||
1. We split such long requests into two requests.
|
|
||||||
2. We join some elements of the vector into new buffers to make it
|
|
||||||
shorter.
|
|
||||||
|
|
||||||
I am wary of (1), because it seems like it may have unintended side
|
|
||||||
effects.
|
|
||||||
|
|
||||||
(2) on the other hand seems relatively simple to implement, with
|
|
||||||
hopefully few side effects, so this patch does that.
|
|
||||||
|
|
||||||
To do this, the use of qemu_iovec_init_extended() in bdrv_pad_request()
|
|
||||||
is effectively replaced by the new function bdrv_create_padded_qiov(),
|
|
||||||
which not only wraps the request IOV with padding head/tail, but also
|
|
||||||
ensures that the resulting vector will not have more than IOV_MAX
|
|
||||||
elements. Putting that functionality into qemu_iovec_init_extended() is
|
|
||||||
infeasible because it requires allocating a bounce buffer; doing so
|
|
||||||
would require many more parameters (buffer alignment, how to initialize
|
|
||||||
the buffer, and out parameters like the buffer, its length, and the
|
|
||||||
original elements), which is not reasonable.
|
|
||||||
|
|
||||||
Conversely, it is not difficult to move qemu_iovec_init_extended()'s
|
|
||||||
functionality into bdrv_create_padded_qiov() by using public
|
|
||||||
qemu_iovec_* functions, so that is what this patch does.
|
|
||||||
|
|
||||||
Because bdrv_pad_request() was the only "serious" user of
|
|
||||||
qemu_iovec_init_extended(), the next patch will remove the latter
|
|
||||||
function, so the functionality is not implemented twice.

|
|
||||||
|
|
||||||
bdrv_pad_request() relies on requests' lengths not to exceed SIZE_MAX,
|
|
||||||
which bdrv_check_qiov_request() does not guarantee.
|
|
||||||
|
|
||||||
bdrv_check_request32() however will guarantee this, and both of
|
|
||||||
bdrv_pad_request()'s callers (bdrv_co_preadv_part() and
|
|
||||||
bdrv_co_pwritev_part()) already run it before calling
|
|
||||||
bdrv_pad_request(). Therefore, bdrv_pad_request() can safely call
|
|
||||||
bdrv_check_request32() without expecting error, too.
|
|
||||||
|
|
||||||
In effect, this patch will not change guest-visible behavior. It is a
|
|
||||||
clean-up to tighten a condition to match what is guaranteed by our
|
|
||||||
callers, and which exists purely to show clearly why the subsequent
|
|
||||||
assertion (`assert(*bytes <= SIZE_MAX)`) is always true.
|
|
||||||
|
|
||||||
Note there is a difference between the interfaces of
|
|
||||||
bdrv_check_qiov_request() and bdrv_check_request32(): The former takes
|
|
||||||
an errp, the latter does not, so we can no longer just pass
|
|
||||||
&error_abort. Instead, we need to check the returned value. While we
|
|
||||||
do expect success (because the callers have already run this function),
|
|
||||||
an assert(ret == 0) is not much simpler than just to return an error if
|
|
||||||
it occurs, so let us handle errors by returning them up the stack now.

|
RH-MergeRequest: 222: Allow concurrent BlockBackend context changes
|
||||||

RH-Commit: [1/2] 9e1b535f60f7afa94a0817dc3e71136e41631c71 (hreitz/qemu-kvm-c-9-s)
|
||||||
|
|
||||||
|
Since AioContext locks have been removed, a BlockBackend's AioContext
|
||||||
|
may really change at any time (only exception is that it is often
|
||||||
|
confined to a drained section, as noted in this patch). Therefore,
|
||||||
|
blk_get_aio_context() cannot rely on its root node's context always
|
||||||
|
matching that of the BlockBackend.
|
||||||
|
|
||||||
|
In practice, whether they match does not matter anymore anyway: Requests
|
||||||
|
can be sent to BDSs from any context, so anyone who requests the BB's
|
||||||
|
context should have no reason to require the root node to have the same
|
||||||
|
context. Therefore, we can and should remove the assertion to that
|
||||||
|
effect.
|
||||||
|
|
||||||
|
In addition, because the context can be set and queried from different
|
||||||
|
threads concurrently, it has to be accessed with atomic operations.

||||||

RH-Commit: [1/4] 8ebf8486b082c30ca1b39a6ede35e471eaaccfa3 (kmwolf/centos-qemu-kvm)
|
|
||||||
|
|
||||||
These functions must not be called in coroutine context, because they
|
|
||||||
need write access to the graph.

RH-Commit: [2/6] 1ccd0ef56182bb5e2374c3b5be98ee1ec05066d6 (sgarzarella/qemu-kvm-c-9-s)
|
|
||||||
|
|
||||||
qemu_open() in blkio_virtio_blk_common_open() is used to open the
|
|
||||||
character device (e.g. /dev/vhost-vdpa-0 or /dev/vfio/vfio) or in
|
|
||||||
the future eventually the unix socket.
|
|
||||||
|
|
||||||
In all these cases we cannot open the path in read-only mode,
|
|
||||||
when the `read-only` option of blockdev is on, because the exchange
|
|
||||||
of IOCTL commands for example will fail.
|
|
||||||
|
|
||||||
In order to open the device read-only, we have to use the `read-only`
|
|
||||||
property of the libblkio driver as we already do in blkio_file_open().

||||||

|
|
||||||
|
|
||||||
Until libblkio 1.3.0, virtio-blk drivers had completion eventfd
|
|
||||||
notifications enabled from the start, but from the next releases
|
|
||||||
this is no longer the case, so we have to explicitly enable them.
|
|
||||||
|
|
||||||
In fact, the libblkio documentation says they could be disabled,
|
|
||||||
so we should always enable them at the start if we want to be
|
|
||||||
sure to get completion eventfd notifications:
|
|
||||||
|
|
||||||
By default, the driver might not generate completion events for
|
|
||||||
requests so it is necessary to explicitly enable the completion
|
|
||||||
file descriptor before use:
|
|
||||||
|
|
||||||
void blkioq_set_completion_fd_enabled(struct blkioq *q, bool enable);
|
|
||||||
|
|
||||||
I discovered this while trying a development version of libblkio:
|
|
||||||
the guest kernel hangs during boot, while probing the device.

RH-Commit: [1/2] c85df95824f4889526a73527771dec9efcb06926 (stefanha/centos-stream-qemu-kvm)
|
|
||||||
|
|
||||||
When QEMU is built with --enable-modules, the module_block.py script
|
|
||||||
parses block/*.c to find block drivers that are built as modules. The
|
|
||||||
script generates a table of block drivers called block_driver_modules[].
|
|
||||||
This table is used for block driver module loading.
|
|
||||||
|
|
||||||
The blkio.c driver uses macros to define its BlockDriver structs. This
|
|
||||||
was done to avoid code duplication but the module_block.py script is
|
|
||||||
unable to parse the macro. The result is that libblkio-based block
|
|
||||||
drivers can be built as modules but will not be found at runtime.
|
|
||||||
|
|
||||||
One fix is to make the module_block.py script or build system fancier so
|
|
||||||
it can parse C macros (e.g. by parsing the preprocessed source code). I
|
|
||||||
chose not to do this because it raises the complexity of the build,
|
|
||||||
making future issues harder to debug.
|
|
||||||
|
|
||||||
Keep things simple: use the macro to avoid duplicating BlockDriver
|
|
||||||
function pointers but define .format_name and .protocol_name manually
|
|
||||||
for each BlockDriver. This way the module_block.py is able to parse the
|
|
||||||
code.
|
|
||||||
|
|
||||||
Also get rid of the block driver name macros (e.g. DRIVER_IO_URING)
|
|
||||||
because module_block.py cannot parse them either.

RH-Commit: [3/6] c356108d7dfe1ba2098c094f8d12b6e40853560c (sgarzarella/qemu-kvm-c-9-s)
|
|
||||||
|
|
||||||
This is in preparation for the next patch, where for virtio-blk
|
|
||||||
drivers we need to handle the failure of blkio_connect().
|
|
||||||
|
|
||||||
Let's also rename the *_open() functions to *_connect() to make
|
|
||||||
the code reflect the changes applied.

RH-Commit: [4/6] 14ebc1f333617ce22c68693dec1c9a186d4f8a08 (sgarzarella/qemu-kvm-c-9-s)
|
|
||||||
|
|
||||||
libblkio 1.3.0 added support of "fd" property for virtio-blk-vhost-vdpa
|
|
||||||
driver. In QEMU, starting from commit cad2ccc395 ("block/blkio: use
|
|
||||||
qemu_open() to support fd passing for virtio-blk") we are using
|
|
||||||
`blkio_get_int(..., "fd")` to check if the "fd" property is supported
|
|
||||||
for all the virtio-blk-* driver.
|
|
||||||
|
|
||||||
Unfortunately that property is also available for those driver that do
|
|
||||||
not support it, such as virtio-blk-vhost-user.
|
|
||||||
|
|
||||||
So, `blkio_get_int()` is not enough to check whether the driver supports
|
|
||||||
the `fd` property or not. This is because the virito-blk common libblkio
|
|
||||||
driver only checks whether or not `fd` is set during `blkio_connect()`
|
|
||||||
and fails with -EINVAL for those transports that do not support it
|
|
||||||
(all except vhost-vdpa for now).
|
|
||||||
|
|
||||||
So let's handle the `blkio_connect()` failure, retrying it using `path`
|
|
||||||
directly.

||||||

RH-Commit: [6/6] d57aafb2c3a8ed13aa3c6dcce5525a9cc8f5aa21 (sgarzarella/qemu-kvm-c-9-s)
|
|
||||||
|
|
||||||
Setting the `fd` property fails with virtio-blk-* libblkio drivers
|
|
||||||
that do not support fd passing since
|
|
||||||
https://gitlab.com/libblkio/libblkio/-/merge_requests/208.
|
|
||||||
|
|
||||||
Getting the `fd` property, on the other hand, always succeeds for
|
|
||||||
virtio-blk-* libblkio drivers even when they don't support fd passing.
|
|
||||||
|
|
||||||
This patch switches to setting the `fd` property because it is a
|
|
||||||
better mechanism for probing fd passing support than getting the `fd`
|
|
||||||
property.

|
|
||||||
|
|
||||||
Some virtio-blk drivers (e.g. virtio-blk-vhost-vdpa) supports the fd
|
|
||||||
passing. Let's expose this to the user, so the management layer
|
|
||||||
can pass the file descriptor of an already opened path.
|
|
||||||
|
|
||||||
If the libblkio virtio-blk driver supports fd passing, let's always
|
|
||||||
use qemu_open() to open the `path`, so we can handle fd passing
|
|
||||||
from the management layer through the "/dev/fdset/N" special path.

reader_count() is a performance bottleneck because the global

aio_context_list_lock mutex causes thread contention. Put this debugging

assertion behind a new ./configure --enable-debug-graph-lock option and

disable it by default.

The --enable-debug-graph-lock option is also enabled by the more general

--enable-debug option.

RH-Commit: [26/26] cde767bcdc626e90721792e3889952057a548ac5 (kmwolf/centos-qemu-kvm)
|
||||||
|
|
||||||
|
Use qemu_get_current_aio_context() in mixed wrappers and coroutine
|
||||||
|
wrappers so that code runs in the caller's AioContext instead of moving
|
||||||
|
to the BlockDriverState's AioContext. This change is necessary for the
|
||||||
|
multi-queue block layer where any thread can call into the block layer.
|
||||||
|
|
||||||
|
Most wrappers are IO_CODE where it's safe to use the current AioContext
|
||||||
|
nowadays. BlockDrivers and the core block layer use their own locks and
|
||||||
|
no longer depend on the AioContext lock for thread-safety.
|
||||||
|
|
||||||
|
The bdrv_create() wrapper invokes GLOBAL_STATE code. Using the current
|
||||||
|
AioContext is safe because this code is only called with the BQL held
|
||||||
|
from the main loop thread.

RH-Commit: [4/26] 74c7daf805daefe706378308c3afeb28d861164b (kmwolf/centos-qemu-kvm)
|
||||||
|
|
||||||
|
The file-posix block driver currently only sets up Linux AIO and
|
||||||
|
io_uring in the BDS's AioContext. In the multi-queue block layer we must
|
||||||
|
be able to submit I/O requests in AioContexts that do not have Linux AIO
|
||||||
|
and io_uring set up yet since any thread can call into the block driver.
|
||||||
|
|
||||||
|
Set up Linux AIO and io_uring for the current AioContext during request
|
||||||
|
submission. We lose the ability to return an error from
|
||||||
|
.bdrv_file_open() when Linux AIO and io_uring setup fails (e.g. due to
|
||||||
|
resource limits). Instead the user only gets warnings and we fall back
|
||||||
|
to aio=threads. This is still better than a fatal error after startup.

Remove them.

RH-MergeRequest: 214: Remove AioContext lock
|

RH-Commit: [25/26] 395e18fb40d28d4bc961acee1a00da7f60748076 (kmwolf/centos-qemu-kvm)
|
||||||
|
|
||||||
|
The AioContext lock no longer exists.
|
||||||
|
|
||||||
|
There is one noteworthy change:
|
||||||
|
|
||||||
|
- * More specifically, these functions use BDRV_POLL_WHILE(bs), which
|
||||||
|
- * requires the caller to be either in the main thread and hold
|
||||||
|
- * the BlockdriverState (bs) AioContext lock, or directly in the
|
||||||
|
- * home thread that runs the bs AioContext. Calling them from
|
||||||
|
- * another thread in another AioContext would cause deadlocks.
|
||||||
|
+ * More specifically, these functions use BDRV_POLL_WHILE(bs), which requires
|
||||||
|
+ * the caller to be either in the main thread or directly in the home thread
|
||||||
|
+ * that runs the bs AioContext. Calling them from another thread in another
|
||||||
|
+ * AioContext would cause deadlocks.
|
||||||
|
|
||||||
|
I am not sure whether deadlocks are still possible. Maybe they have just
|
||||||
|
moved to the fine-grained locks that have replaced the AioContext. Since
|
||||||
|
I am not sure if the deadlocks are gone, I have kept the substance
|
||||||
|
unchanged and just removed mention of the AioContext.

chardev/char-socket: Fix TLS io channels sending too much data to the backend
|
||||||
|
|
||||||
|
Commit ffda5db65a ("io/channel-tls: fix handling of bigger read buffers")
|
||||||
|
changed the behavior of the TLS io channels to schedule a second reading
|
||||||
|
attempt if there is still incoming data pending. This caused a regression
|
||||||
|
with backends like the sclpconsole that check in their read function that
|
||||||
|
the sender does not try to write more bytes to it than the device can
|
||||||
|
currently handle.
|
||||||
|
|
||||||
|
The problem can be reproduced like this:
|
||||||
|
|
||||||
|
1) In one terminal, do this:
|
||||||
|
|
||||||
|
mkdir qemu-pki
|
||||||
|
cd qemu-pki
|
||||||
|
openssl genrsa 2048 > ca-key.pem
|
||||||
|
openssl req -new -x509 -nodes -days 365000 -key ca-key.pem -out ca-cert.pem
|
||||||
|
# enter some dummy value for the cert
|
||||||
|
openssl genrsa 2048 > server-key.pem
|
||||||
|
openssl req -new -x509 -nodes -days 365000 -key server-key.pem \
|
||||||
|
-out server-cert.pem
|
||||||
|
# enter some other dummy values for the cert
|
||||||
|
|
||||||
|
gnutls-serv --echo --x509cafile ca-cert.pem --x509keyfile server-key.pem \
|
||||||
|
--x509certfile server-cert.pem -p 8338
|
||||||
|
|
||||||
|
2) In another terminal, do this:
|
||||||
|
|
||||||
|
wget https://download.fedoraproject.org/pub/fedora-secondary/releases/39/Cloud/s390x/images/Fedora-Cloud-Base-39-1.5.s390x.qcow2
|
||||||
|
|
||||||
|
qemu-system-s390x -nographic -nodefaults \
|
||||||
|
-hda Fedora-Cloud-Base-39-1.5.s390x.qcow2 \
|
||||||
|
-object tls-creds-x509,id=tls0,endpoint=client,verify-peer=false,dir=$PWD/qemu-pki \
|
||||||
|
-chardev socket,id=tls_chardev,host=localhost,port=8338,tls-creds=tls0 \
|
||||||
|
-device sclpconsole,chardev=tls_chardev,id=tls_serial
|
||||||
|
|
||||||
|
QEMU then aborts after a second or two with:
|
||||||
|
|
||||||
|
qemu-system-s390x: ../hw/char/sclpconsole.c:73: chr_read: Assertion
|
||||||
|
`size <= SIZE_BUFFER_VT220 - scon->iov_data_len' failed.
|
||||||
|
Aborted (core dumped)
|
||||||
|
|
||||||
|
It looks like the second read does not trigger the chr_can_read() function
|
||||||
|
to be called before the second read, which should normally always be done
|
||||||
|
before sending bytes to a character device to see how much it can handle,
|
||||||
|
so the s->max_size in tcp_chr_read() still contains the old value from the
|
||||||
|
previous read. Let's make sure that we use the up-to-date value by calling
|
||||||
|
tcp_chr_read_poll() again here.
|
||||||
|
|
||||||
|

RH-Commit: [1/3] 842f54349191b0206e68f35a7a80155f5a584942 (berrange/centos-src-qemu)
|
||||||
|
|
||||||
|
The socket chardev often has 2 GSource object registered against the
|
||||||
|
same FD. One is registered all the time and is just intended to handle
|
||||||
|
POLLHUP events, while the other gets registered & unregistered on the
|
||||||
|
fly as the frontend is ready to receive more data or not.
|
||||||
|
|
||||||
|
It is very common for poll() to signal a POLLHUP event at the same time
|
||||||
|
as there is pending incoming data from the disconnected client. It is
|
||||||
|
therefore essential to process incoming data prior to processing HUP.
|
||||||
|
The problem with having 2 GSource on the same FD is that there is no
|
||||||
|
guaranteed ordering of execution between them, so the chardev code may
|
||||||
|
process HUP first and thus discard data.
|
||||||
|
|
||||||
|
This failure scenario is non-deterministic but can be seen fairly
|
||||||
|
reliably by reverting a7077b8e354d90fec26c2921aa2dea85b90dff90, and
|
||||||
|
then running 'tests/unit/test-char', which will sometimes fail with
|
||||||
|
missing data.
|
||||||
|
|
||||||
|
Ideally QEMU would only have 1 GSource, but that's a complex code
|
||||||
|
refactoring job. The next best solution is to try to ensure ordering
|
||||||
|
between the 2 GSource objects. This can be achieved by lowering the
|
||||||
|
priority of the HUP GSource, so that it is never dispatched if the
|
||||||
|
main GSource is also ready to dispatch. Counter-intuitively, lowering
|
||||||
|
the priority of a GSource is done by raising its priority number.

RH-MergeRequest: 234: coroutine: cap per-thread local pool size
|

RH-Commit: [1/2] 5971de1c1e238457925bfb9c4bfc932de857b28d (stefanha/centos-stream-qemu-kvm)
|
||||||
|
|
||||||
|
The coroutine pool implementation can hit the Linux vm.max_map_count
|
||||||
|
limit, causing QEMU to abort with "failed to allocate memory for stack"
|
||||||
|
or "failed to set up stack guard page" during coroutine creation.
|
||||||
|
|
||||||
|
This happens because per-thread pools can grow to tens of thousands of
|
||||||
|
coroutines. Each coroutine causes 2 virtual memory areas to be created.
|
||||||
|
Eventually vm.max_map_count is reached and memory-related syscalls fail.
|
||||||
|
The per-thread pool sizes are non-uniform and depend on past coroutine
|
||||||
|
usage in each thread, so it's possible for one thread to have a large
|
||||||
|
pool while another thread's pool is empty.
|
||||||
|
|
||||||
|
Switch to a new coroutine pool implementation with a global pool that
|
||||||
|
grows to a maximum number of coroutines and per-thread local pools that
|
||||||
|
are capped at hardcoded small number of coroutines.
|
||||||
|
|
||||||
|
This approach does not leave large numbers of coroutines pooled in a
|
||||||
|
thread that may not use them again. In order to perform well it
|
||||||
|
amortizes the cost of global pool accesses by working in batches of
|
||||||
|
coroutines instead of individual coroutines.
|
||||||
|
|
||||||
|
The global pool is a list. Threads donate batches of coroutines to when
|
||||||
|
they have too many and take batches from when they have too few:
|
||||||
|
|
||||||
|
.-----------------------------------.
|
||||||
|
| Batch 1 | Batch 2 | Batch 3 | ... | global_pool
|
||||||
|
`-----------------------------------'
|
||||||
|
|
||||||
|
Each thread has up to 2 batches of coroutines:
|
||||||
|
|
||||||
|
.-------------------.
|
||||||
|
| Batch 1 | Batch 2 | per-thread local_pool (maximum 2 batches)
|
||||||
|
`-------------------'
|
||||||
|
|
||||||
|
The goal of this change is to reduce the excessive number of pooled
|
||||||
|
coroutines that cause QEMU to abort when vm.max_map_count is reached
|
||||||
|
without losing the performance of an adequately sized coroutine pool.

||||||

|
||||||
|
|
||||||
|
Daniel P. Berrangé <berrange@redhat.com> pointed out that the coroutine
|
||||||
|
pool size heuristic is very conservative. Instead of halving
|
||||||
|
max_map_count, he suggested reserving 5,000 mappings for non-coroutine
|
||||||
|
users based on observations of guests he has access to.

RH-Commit: [11/26] a8580463ba6aee4ca248c0b947b9e72bd9e87aab (kmwolf/centos-qemu-kvm)
|
||||||
|
|
||||||
|
Commit abfcd2760b3e ("dma-helpers: prevent dma_blk_cb() vs
|
||||||
|
dma_aio_cancel() race") acquired the AioContext lock inside dma_blk_cb()
|
||||||
|
to avoid a race with scsi_device_purge_requests() running in the main
|
||||||
|
loop thread.
|
||||||
|
|
||||||
|
The SCSI code no longer calls dma_aio_cancel() from the main loop thread
|
||||||
|
while I/O is running in the IOThread AioContext. Therefore it is no
|
||||||
|
longer necessary to take this lock to protect DMAAIOCB fields. The
|
||||||
|
->cb() function also does not require the lock because blk_aio_*() and
|
||||||
|
friends do not need the AioContext lock.
|
||||||
|
|
||||||
|
Both hw/ide/core.c and hw/ide/macio.c also call dma_blk_io() but don't
|
||||||
|
rely on it taking the AioContext lock, so this change is safe.

|
+IOMMUFD BACKEND usage with VFIO
|
||||||
|
+===============================
|
||||||
|
+
|
||||||
|
+(Same meaning for backend/container/BE)
|
||||||
|
+
|
||||||
|
+With the introduction of iommufd, the Linux kernel provides a generic
|
||||||
|
+interface for user space drivers to propagate their DMA mappings to kernel
|
||||||
|
+for assigned devices. While the legacy kernel interface is group-centric,
|
||||||
|
+the new iommufd interface is device-centric, relying on device fd and iommufd.
|
||||||
|
+
|
||||||
|
+To support both interfaces in the QEMU VFIO device, introduce a base container
|
||||||
|
+to abstract the common part of VFIO legacy and iommufd container. So that the
|
||||||
|
+generic VFIO code can use either container.
|
||||||
|
+
|
||||||
|
+The base container implements generic functions such as memory_listener and
|
||||||
|
+address space management whereas the derived container implements callbacks
|
||||||
|
+specific to either legacy or iommufd. Each container has its own way to setup
|
||||||
|
+secure context and dma management interface. The below diagram shows how it
|
||||||
|
+looks like with both containers.

|
||||||

|
||||||
|
+Example configuration
|
||||||
|
+=====================
|
||||||
|
+
|
||||||
|
+Step 1: configure the host device
|
||||||
|
+---------------------------------
|
||||||
|
+
|
||||||
|
+It's exactly same as the VFIO device with legacy VFIO container.
|
||||||
|
+
|
||||||
|
+Step 2: configure QEMU
|
||||||
|
+----------------------
|
||||||
|
+
|
||||||
|
+Interactions with the ``/dev/iommu`` are abstracted by a new iommufd
|
||||||
|
+object (compiled in with the ``CONFIG_IOMMUFD`` option).
|
||||||
|
+
|
||||||
|
+Any QEMU device (e.g. VFIO device) wishing to use ``/dev/iommu`` must
|
||||||
|
+be linked with an iommufd object. It gets a new optional property
|
||||||
|
+named iommufd which allows to pass an iommufd object. Take ``vfio-pci``
|
||||||
|
+device for example:
|
||||||
|
+
|
||||||
|
+.. code-block:: bash
|
||||||
|
+
|
||||||
|
+ -object iommufd,id=iommufd0
|
||||||
|
+ -device vfio-pci,host=0000:02:00.0,iommufd=iommufd0
|
||||||
|
+
|
||||||
|
+Note the ``/dev/iommu`` and VFIO cdev can be externally opened by a
|
||||||
|
+management layer. In such a case the fd is passed, the fd supports a
|
||||||
|
+string naming the fd or a number, for example:
|
||||||
|
+
|
||||||
|
+.. code-block:: bash
|
||||||
|
+
|
||||||
|
+ -object iommufd,id=iommufd0,fd=22
|
||||||
|
+ -device vfio-pci,iommufd=iommufd0,fd=23
|
||||||
|
+
|
||||||
|
+If the ``fd`` property is not passed, the fd is opened by QEMU.
|
||||||
|
+
|
||||||
|
+If no ``iommufd`` object is passed to the ``vfio-pci`` device, iommufd
|
||||||
|
+is not used and the user gets the behavior based on the legacy VFIO
|
||||||
|
+container:
|
||||||
|
+
|
||||||
|
+.. code-block:: bash
|
||||||
|
+
|
||||||
|
+ -device vfio-pci,host=0000:02:00.0
|
||||||
|
+
|
||||||
|
+Supported platform
|
||||||
|
+==================
|
||||||
|
+
|
||||||
|
+Supports x86, ARM and s390x currently.
|
||||||
|
+
|
||||||
|
+Caveats
|
||||||
|
+=======
|
||||||
|
+
|
||||||
|
+Dirty page sync
|
||||||
|
+---------------
|
||||||
|
+
|
||||||
|
+Dirty page sync with iommufd backend is unsupported yet, live migration is
|
||||||
|
+disabled by default. But it can be force enabled like below, low efficient
|
||||||
|
+though.
|
||||||
|
+
|
||||||
|
+.. code-block:: bash
|
||||||
|
+
|
||||||
|
+ -object iommufd,id=iommufd0
|
||||||
|
+ -device vfio-pci,host=0000:02:00.0,iommufd=iommufd0,enable-migration=on
|
||||||
|
+
|
||||||
|
+P2P DMA
|
||||||
|
+-------
|
||||||
|
+
|
||||||
|
+PCI p2p DMA is unsupported as IOMMUFD doesn't support mapping hardware PCI
|
||||||
|
+BAR region yet. Below warning shows for assigned PCI device, it's not a bug.
|
||||||
|
+
|
||||||
|
+.. code-block:: none
|
||||||
|
+
|
||||||
|
+ qemu-system-x86_64: warning: IOMMU_IOAS_MAP failed: Bad address, PCI BAR?
|
||||||
|
+ qemu-system-x86_64: vfio_container_dma_map(0x560cb6cb1620, 0xe000000021000, 0x3000, 0x7f32ed55c000) = -14 (Bad address)
|
||||||
|
+
|
||||||
|
+FD passing with mdev
|
||||||
|
+--------------------
|
||||||
|
+
|
||||||
|
+``vfio-pci`` device checks sysfsdev property to decide if backend is a mdev.
|
||||||
|
+If FD passing is used, there is no way to know that and the mdev is treated
|
||||||
|
+like a real PCI device. There is an error as below if user wants to enable
|
||||||
|
+RAM discarding for mdev.
|
||||||
|
+
|
||||||
|
+.. code-block:: none
|
||||||
|
+
|
||||||
|
+ qemu-system-x86_64: -device vfio-pci,iommufd=iommufd0,x-balloon-allowed=on,fd=9: vfio VFIO_FD9: x-balloon-allowed only potentially compatible with mdev devices
|
||||||
|
+
|
||||||
|
+``vfio-ap`` and ``vfio-ccw`` devices don't have same issue as their backend
|
||||||
|
+devices are always mdev and RAM discarding is force enabled.

How to synchronize with an IOThread

-----------------------------------
|

|
-AioContext is not thread-safe so some rules must be followed when using file

|
-descriptors, event notifiers, timers, or BHs across threads:
|

|
+Variables that can be accessed by multiple threads require some form of

-1. AioContext functions can always be called safely. They handle their
|
||||||
|
-own locking internally.
|
||||||
|
-
|
||||||
|
-2. Other threads wishing to access the AioContext must use
|
||||||
|
-aio_context_acquire()/aio_context_release() for mutual exclusion. Once the
|
||||||
|
-context is acquired no other thread can access it or run event loop iterations
|
||||||
|
-in this AioContext.
|
||||||
|
-
|
||||||
|
-Legacy code sometimes nests aio_context_acquire()/aio_context_release() calls.
|
||||||
|
-Do not use nesting anymore, it is incompatible with the BDRV_POLL_WHILE() macro
|
||||||
|
-used in the block layer and can lead to hangs.
|
||||||
|
-
|
||||||
|
-There is currently no lock ordering rule if a thread needs to acquire multiple
|
||||||
|
-AioContexts simultaneously. Therefore, it is only safe for code holding the
|
||||||
|
-QEMU global mutex to acquire other AioContexts.
|
||||||
|
+AioContext functions like aio_set_fd_handler(), aio_set_event_notifier(),
|
||||||
|
+aio_bh_new(), and aio_timer_new() are thread-safe. They can be used to trigger
|
||||||
|
+activity in an IOThread.
|
||||||
|
|
||||||
|
Side note: the best way to schedule a function call across threads is to call
|
||||||
|
-aio_bh_schedule_oneshot(). No acquire/release or locking is needed.

RH-Commit: [2/4] 39d42fb527aad0491a018743289de7b762108317 (kmwolf/centos-qemu-kvm)
|
|
||||||
|
|
||||||
In QEMU 8.0, we've been seeing deadlocks in bdrv_graph_wrlock(). They
|
|
||||||
come from callers that hold an AioContext lock, which is not allowed
|
|
||||||
during polling. In theory, we could temporarily release the lock, but
|
|
||||||
callers are inconsistent about whether they hold a lock, and if they do,
|
|
||||||
some are also confused about which one they hold. While all of this is
|
|
||||||
fixable, it's not trivial, and the best course of action for 8.0.1 is
|
|
||||||
probably just disabling the graph locking code temporarily.
|
|
||||||
|
|
||||||
We don't currently rely on graph locking yet. It is supposed to replace
|
|
||||||
the AioContext lock eventually to enable multiqueue support, but as long
|
|
||||||
as we still have the AioContext lock, it is sufficient without the graph
|
|
||||||
lock. Once the AioContext lock goes away, the deadlock doesn't exist any
|
|
||||||
more either and this commit can be reverted. (Of course, it can also be
|
|
||||||
reverted while the AioContext lock still exists if the callers have been
|
|
||||||
fixed.)

https://issues.redhat.com/browse/RHEL-20341
|
||||||
|
|
||||||
|
Let's implement the get_min_alignment() callback for memory devices, and
|
||||||
|
copy for the device memory region the alignment of the host memory
|
||||||
|
region. This mimics what virtio-mem does, and allows for re-introducing
|
||||||
|
proper alignment checks for the memory region size (where we don't care
|
||||||
|
about additional device requirements) in memory device core.

|
||||||
|
|
||||||
i440fx machine versions 2.3 and newer supports dynamic ram
|
|
||||||
resizing. See commit a1666142db6233 ("acpi-build: make ROMs RAM blocks resizeable") .
|
|
||||||
Currently supported all q35 machine types (versions 2.4 and newer) supports
|
|
||||||
resizable RAM/ROM blocks.Therefore the warning generated when the ACPI table
|
|
||||||
size exceeds a pre-defined value does not apply to those machine versions.
|
|
||||||
Add a check limiting the warning message to only those machines that does not
|
|
||||||
support expandable ram blocks (that is, i440fx machines with version 2.2
|
|
||||||
and older).

|
|
||||||
|
|
||||||
There are two ARM machines where NUMA is aware: 'virt' and 'sbsa-ref'.
|
|
||||||
Both of them are required to follow cluster-NUMA-node boundary. To
|
|
||||||
enable the validation to warn about the irregular configuration where
|
|
||||||
multiple CPUs in one cluster have been associated with different NUMA
|
|
||||||
nodes.

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2229133
|
|
||||||
|
|
||||||
The implementation of the SMMUv3 has multiple places where it reads a
|
|
||||||
data structure from the guest and directly operates on it without
|
|
||||||
doing a guest-to-host endianness conversion. Since all SMMU data
|
|
||||||
structures are little-endian, this means that the SMMU doesn't work
|
|
||||||
on a big-endian host. In particular, this causes the Avocado test
|
|
||||||
machine_aarch64_virt.py:Aarch64VirtMachine.test_alpine_virt_tcg_gic_max
|
|
||||||
to fail on an s390x host.
|
|
||||||
|
|
||||||
Add appropriate byte-swapping on reads and writes of guest in-memory
|
|
||||||
data structures so that the device works correctly on big-endian
|
|
||||||
hosts.
|
|
||||||
|
|
||||||
As part of this we constrain queue_read() to operate only on Cmd
|
|
||||||
structs and queue_write() on Evt structs, because in practice these
|
|
||||||
are the only data structures the two functions are used with, and we
|
|
||||||
need to know what the data structure is to be able to byte-swap its
|
|
||||||
parts correctly.

RH-Commit: [1/1] 4097ba5133a67126e30b84202cb40df4e019c5f4
|
||||||
|
|
||||||
|
Upstream: RHEL-only
|
||||||
|
Brew: https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=57927352
|
||||||
|
|
||||||
|
There are 3 high memory regions for GICv3 or GICv4 redistributor, PCI
|
||||||
|
ECAM and PCI MMIO. Each of them has a property introduced by upstream
|
||||||
|
commit 6a48c64eec ("hw/arm/virt: Add properties to disable high memory
|
||||||
|
regions") so that the corresponding high memory region can be disabled.
|
||||||
|
|
||||||
|
It's notable that another property ("compact-highmem") introduced by
|
||||||
|
upstream commit f40408a9fe ("hw/arm/virt: Add 'compact-highmem' property")
|
||||||
|
so that the compact high memory region layout during assignment can be
|
||||||
|
disabled, compatible to the old machine types. However, we don't have
|
||||||
|
the compatible issue since the compact high memory region layout is
|
||||||
|
always kept as disabled until RHEL9.2.0 machine type and onwards.
|
||||||
|
|
||||||
|
Expose those 3 properties: "highmem-redists", "highmem-ecam" and
|
||||||
|
"highmem-mmio". The property "compact-highmem" is kept as hidden.

RH-Commit: [1/1] bcdf6493bbd6d7b52b0b88ff44441d22aeddfde2 (eauger1/centos-qemu-kvm)
|
||||||
|
|
||||||
|
arm_rhel_compat is not added for virt-rhel9.4.0 machine causing
|
||||||
|
the efi-virtio.rom to be looked for when instantiating a virtio-net-pci
|
||||||
|
device and it won't be found since not shipped on ARM. This is a
|
||||||
|
regression compared to 9.2.
|
||||||
|
|
||||||
|
Actually we do not need any rom file for any virtio-net-pci variant
|
||||||
|
because edk2 already brings the functionality. So for 9.4 onwards, we
|
||||||
|
want to set romfiles to "" for all of them.
|
||||||
|
|
||||||
|
However at the moment we apply arm_rhel_compat from the latest
|
||||||
|
rhel*_virt_options(). This is not aligned with the generic compat
|
||||||
|
usage which sets compats for a given machine type to accomodate for
|
||||||
|
changes that occured after its advent. Here we are somehow abusing
|
||||||
|
the compat infra to set general driver options that should apply for
|
||||||
|
all machines. On top of that this is really error prone and we have
|
||||||
|
forgotten to add arm_rhel_compat several times in the past.
|
||||||
|
|
||||||
|
So let's introduce set_arm_rhel_compat() being called before any
|
||||||
|
*virt_options in the non abstract machine class. That way the setting
|
||||||
|
will apply to any machine type without any need to add it in any
|
||||||
|
future machine types.
|
||||||
|
|
||||||
|
For < 9.4 machines we don't really care keeping non void romfiles
|
||||||
|
for transitional and non transitional devices because anyway this was
|
||||||
|
not working. So let's keep things simple and apply the new defaults for
|
||||||
|
all RHEL9 machine types.
|
||||||
|
|
||||||
|
Finally, to follow the generic pattern we should set hw_compat_rhel_9_0
|
||||||
|
in 9.0 machine as it is done on x86 or ccw. This has no consequence on
|
||||||
|
aarch64 because it only contains x86 stuff but that helps understanding
|
||||||
|
the consistency.

commit: a0204a5ed091dfe79aced7ec8f3ce1931fd25816
|
||||||
|
Author: Bernhard Beschow <shentey@gmail.com>
|
||||||
|
|
||||||
|
Handling most of smbios data generation in the machine_done notifier is similar
|
||||||
|
to how the ARM virt machine handles it which also calls smbios_set_defaults()
|
||||||
|
there. The result is that all pc machines are freed from explicitly worrying
|
||||||
|
about smbios setup.

due to missing 4d3457fef9 (w/i386/pc: Merge pc_guest_info_init() into pc_machine_initfn())

|
|
||||||
qemu-system-x86_64: error while loading state for instance 0x0 of device '0000:00:02.0/e1000e'
|
|
||||||
qemu-system-x86_64: load of migration failed: Invalid argument
|
|
||||||
|
|
||||||
The above test migrated a 7.2 machine type from QEMU master to QEMU 7.2.0,
|
|
||||||
with this cmdline:
|
|
||||||
|
|
||||||
./qemu-system-x86_64 -M pc-q35-7.2 [-incoming XXX]
|
|
||||||
|
|
||||||
In order to fix this, property x-pcie-err-unc-mask was introduced to
|
|
||||||
control when PCI_ERR_UNCOR_MASK is enabled. This property is enabled by
|
|
||||||
default, but is disabled if machine type <= 7.2.
|
|
||||||

RH-Commit: [47/67] c1a40cdab9bf62b16cb428d57a20b3e0eaa6de38 (eauger1/centos-qemu-kvm)
|
||||||
|
|
||||||
|
When the legacy and iommufd backends were introduced, a set of common
|
||||||
|
vfio-pci routines were exported in pci.c for both backends to use :
|
||||||
|
|
||||||
|
vfio_pci_pre_reset
|
||||||
|
vfio_pci_get_pci_hot_reset_info
|
||||||
|
vfio_pci_host_match
|
||||||
|
vfio_pci_post_reset
|
||||||
|
|
||||||
|
This introduced a build failure on PPC when --without-default-devices
|
||||||
|
is use because VFIO is always selected in ppc/Kconfig but VFIO_PCI is
|
||||||
|
not.
|
||||||
|
|
||||||
|
Use an 'imply VFIO_PCI' in ppc/Kconfig and bypass compilation of the
|
||||||
|
VFIO EEH hooks routines defined in hw/ppc/spapr_pci_vfio.c with
|
||||||
|
CONFIG_VFIO_PCI.

hw/scsi/lsi53c895a: Fix reentrancy issues in the LSI controller (CVE-2023-0330)
|
|
||||||
|
|
||||||
We cannot use the generic reentrancy guard in the LSI code, so
|
|
||||||
we have to manually prevent endless reentrancy here. The problematic
|
|
||||||
lsi_execute_script() function has already a way to detect whether
|
|
||||||
too many instructions have been executed - we just have to slightly
|
|
||||||
change the logic here that it also takes into account if the function
|
|
||||||
has been called too often in a reentrant way.
|
|
||||||
|
|
||||||
The code in fuzz-lsi53c895a-test.c has been taken from an earlier
|
|
||||||
patch by Mauro Matteo Cascella.

Commit 3d779abafe ("vfio/common: Introduce a global VFIODevice list")
|
||||||
|
introduced a global VFIODevice list, but forgot to update the list
|
||||||
|
element field name when iterating over the new list. Change the code
|
||||||
|
to use the correct list element field.

hw/vfio/pci-quirks: Sanitize capability pointer
|
|
||||||
|
|
||||||
Coverity reports a tained scalar when traversing the capabilities
|
|
||||||
chain (CID 1516589). In practice I've never seen a device with a
|
|
||||||
chain so broken as to cause an issue, but it's also pretty easy to
|
|
||||||
sanitize.

hw/vfio/pci-quirks: Support alternate offset for GPUDirect Cliques
|
|
||||||
|
|
||||||
NVIDIA Turing and newer GPUs implement the MSI-X capability at the offset
|
|
||||||
previously reserved for use by hypervisors to implement the GPUDirect
|
|
||||||
Cliques capability. A revised specification provides an alternate
|
|
||||||
location. Add a config space walk to the quirk to check for conflicts,
|
|
||||||
allowing us to fall back to the new location or generate an error at the
|
|
||||||
quirk setup rather than when the real conflicting capability is added
|
|
||||||
should there be no available location.

|
|
||||||
In the virtio_iommu_handle_command() when a PROBE request is handled,
|
|
||||||
output_size takes a value greater than the tail size and on a subsequent
|
|
||||||
iteration we can get a stack out-of-band access. Initialize the
|
|
||||||
output_size on each iteration.
|
|
||||||
|
|

i386/sev: Update checks and information related to reduced-phys-bits
|
|
||||||
|
|
||||||
The value of the reduced-phys-bits parameter is propogated to the CPUID
|
|
||||||
information exposed to the guest. Update the current validation check to
|
|
||||||
account for the size of the CPUID field (6-bits), ensuring the value is
|
|
||||||
in the range of 1 to 63.
|
|
||||||
|
|
||||||
Maintain backward compatibility, to an extent, by allowing a value greater
|
|
||||||
than 1 (so that the previously documented value of 5 still works), but not
|
|
||||||
allowing anything over 63.

Subject: [PATCH] io: remove io watch if TLS channel is closed during handshake
|
|
||||||
MIME-Version: 1.0

|
||||||
Content-Type: text/plain; charset=UTF-8
|
|

Content-Transfer-Encoding: 8bit
|
|
||||||
|
|
||||||
The TLS handshake make take some time to complete, during which time an
|
|
||||||
I/O watch might be registered with the main loop. If the owner of the
|
|
||||||
I/O channel invokes qio_channel_close() while the handshake is waiting
|
|
||||||
to continue the I/O watch must be removed. Failing to remove it will
|
|
||||||
later trigger the completion callback which the owner is not expecting
|
|
||||||
to receive. In the case of the VNC server, this results in a SEGV as
|
|
||||||
vnc_disconnect_start() tries to shutdown a client connection that is
|
|
||||||
already gone / NULL.

|

|
|
||||||
|
This replicates the scenario in which the bug was reported.
|
||||||
|
Unfortunately this relies on actually executing a guest (so that the
|
||||||
|
firmware initialises the virtio-blk device and moves it to its
|
||||||
|
configured iothread), so this can't make use of the qtest accelerator
|
||||||
|
like most other test cases. I tried to find a different easy way to
|
||||||
|
trigger the bug, but couldn't find one.

|
|
||||||
|
|
||||||
This tests exercises graph locking, draining, and graph modifications
|
|
||||||
with AioContext switches a lot. Amongst others, it serves as a
|
|
||||||
regression test for bdrv_graph_wrlock() deadlocking because it is called
|
|
||||||
with a locked AioContext and for AioContext handling in the NBD server.

|
|
||||||
|
|
||||||
This tests that trying to resize an image with QMP block_resize doesn't
|
|
||||||
hang or otherwise fail when the image is attached to a device running in
|
|
||||||
an iothread.
|
|
||||||
|
|
||||||
This is a regression test for the recent fix that changed
|
|
||||||
qmp_block_resize, which is a coroutine based QMP handler, to avoid
|
|
||||||
calling no_coroutine_fns directly.

|
|
||||||
This is a downstream-only patch that is necessary because the default
|
|
||||||
CPU in RHEL is marked as deprecated. This makes test cases fail due to
|
|
||||||
the warning in the output:
|
|
||||||
|
|
||||||
qemu-system-x86_64: warning: CPU model qemu64-x86_64-cpu is deprecated -- use at least 'Nehalem' / 'Opteron_G4', or 'host' / 'max'

RH-Commit: [7/17] 8dd20acc5b1e992294ed422e80897a9c221940dd (stefanha/centos-stream-qemu-kvm)
|
||||||
|
|
||||||
|
Add a filter function for QMP responses that contain QEMU's
|
||||||
|
automatically generated node ids. The ids change between runs and must
|
||||||
|
be masked in the reference output.
|
||||||
|
|
||||||
|
The next commit will use this new function.

|
||||||
|
|
||||||
|
Since Python 3.11 asyncio.TimeoutError is an alias for TimeoutError, but
|
||||||
|
in older versions it's not. We really have to catch asyncio.TimeoutError
|
||||||
|
here, otherwise a slow test run will fail (as has happened multiple
|
||||||
|
times on CI recently).
