Subject: globally limit the maximum number of CPUs
|
||||
|
||||
We now globally limit the number of VCPUs.
|
||||
Especially, there is no way one can specify more than
|
||||
max_cpus VCPUs for a VM.
|
||||
|
||||
This allows us the restore the ppc max_cpus limitation to the upstream
|
||||
default and minimize the ppc hack in kvm-all.c.

|

qcow2 v3 has been around for a long time (since QEMU 1.1/RHEL 7), so
|
||||
there is no real reason any more to use it. People still using it might
|
||||
do so unintentionally. Warn about it and suggest upgrading during the
|
||||
RHEL 9 timeframe so that the code can possibly be disabled in RHEL 10.
|
||||
|
||||
The warning is restricted to read-write mode and the system emulator.
|
||||
The primary motivation for not having it in qemu-img is that 'qemu-img
|
||||
amend' for upgrades would warn otherwise. It also avoids having to make
|
||||
too many changes to the test suite.
|
||||
|
||||
bdrv_uses_whitelist() is used as a proxy for deciding whether we are
|
||||
running in a tool or the system emulator. This is not entirely clean,
|
||||
but it's what is available and the same function qcow2_do_open() already
|
||||
uses it this way for another warning.

|

|
||||
We need a fix for RHEL 7.4 and 7.3.z, but unfortunately upstream isn't
|
||||
ready. If it were, the changes will be too invasive. To have an idea:
|
||||
|
||||
https://lists.gnu.org/archive/html/qemu-devel/2017-05/msg05400.html
|
||||
|
||||
is an incomplete attempt to fix part of the issue, and the remaining
|
||||
work unfortunately involve even more complex changes.
|
||||
|
||||
As a band-aid, this partially reverts the effect of ef8875b
|
||||
(virtio-scsi: Remove op blocker for dataplane, since v2.7). We cannot
|
||||
simply revert that commit as a whole because we already shipped it in
|
||||
qemu-kvm-rhev 7.3, since when, block jobs has been possible. We should
|
||||
only block what has been broken. Also, faithfully reverting the above
|
||||
commit means adding back the removed op blocker, but that is not enough,
|
||||
because it still crashes when inserting media into an initially empty
|
||||
scsi-cd.
|
||||
|
||||
All in all, scsi-cd on virtio-scsi-dataplane has basically been unusable
|
||||
unless the scsi-cd never enters an empty state, so, disable it
|
||||
altogether. Otherwise it would be much more difficult to avoid
|
||||
crashing.

|

|
||||
Most current POWER guests require 64kiB page support, so that's the default
|
||||
for the cap-hpt-max-pagesize option in qemu which limits available guest
|
||||
page sizes. We warn if the value is set smaller than that, but don't
|
||||
outright fail upstream, because we need to allow for the possibility of
|
||||
guest (and/or host) kernels configured for 4kiB page sizes.
|
||||
|
||||
Downstream, however, we simply don't support 4kiB pagesize configured
|
||||
kernels in guest or host, so we can have qemu simply error out in this
|
||||
situation.
|
||||
|
||||
Testing: Attempted to start a guest with cap-hpt-max-page-size=4k and verified
|
||||
it failed immediately with a qemu error

but not "virtio-net-pci-transitional" and

"virtio-net-pci-non-transitional". The solution is to use the

"virtio-net-pci-base" type in compat_props.

An equivalent fix will be submitted for hw_compat_5_2 upstream.

Add compatibility handling for the rhel8.5.0 machine type (and
|
||||
recursively older, of course).
|
||||
|
||||
Based on the following upstream commits:
|
||||
|
||||
463e50da8b - s390x/cpumodel: Bump up QEMU model to a stripped-down IBM z14 GA2
|
||||
30e398f796 - s390x/cpumodel: Add more feature to gen16 default model
|
||||
4a0af2930a - machine: Prefer cores over sockets in smp parsing since 6.2
|
||||
2b52619994 - machine: Move smp_prefer_sockets to struct SMPCompatProps

KVM: keep track of running ioctls
|
||||
|
||||
Using the new accel-blocker API, mark where ioctls are being called
|
||||
in KVM. Next, we will implement the critical section that will take
|
||||
care of performing memslots modifications atomically, therefore
|
||||
preventing any new ioctl from running and allowing the running ones
|
||||
to finish.

|
||||
|
||||
Some AMD processors expose the PKRU extended save state even if they do not have
|
||||
the related PKU feature in CPUID. Worse, when they do they report a size of
|
||||
64, whereas the expected size of the PKRU extended save state is 8, therefore
|
||||
the esa->size == eax assertion does not hold.
|
||||
|
||||
The state is already ignored by KVM_GET_SUPPORTED_CPUID because it
|
||||
was not enabled in the host XCR0. However, QEMU kvm_cpu_xsave_init()
|
||||
runs before QEMU invokes arch_prctl() to enable dynamically-enabled
|
||||
save states such as XTILEDATA, and KVM_GET_SUPPORTED_CPUID hides save
|
||||
states that have yet to be enabled. Therefore, kvm_cpu_xsave_init()
|
||||
needs to consult the host CPUID instead of KVM_GET_SUPPORTED_CPUID,
|
||||
and dies with an assertion failure.
|
||||
|
||||
When setting up the ExtSaveArea array to match the host, ignore features that
|
||||
KVM does not report as supported. This will cause QEMU to skip the incorrect
|
||||
CPUID leaf instead of tripping the assertion.

|
||||
|
||||
Add flags to io_writev and introduce io_flush as optional callback to
|
||||
QIOChannelClass, allowing the implementation of zero copy writes by
|
||||
subclasses.
|
||||
|
||||
How to use them:
|
||||
- Write data using qio_channel_writev*(...,QIO_CHANNEL_WRITE_FLAG_ZERO_COPY),
|
||||
- Wait write completion with qio_channel_flush().
|
||||
|
||||
Notes:
|
||||
As some zero copy write implementations work asynchronously, it's
|
||||
recommended to keep the write buffer untouched until the return of
|
||||
qio_channel_flush(), to avoid the risk of sending an updated buffer
|
||||
instead of the buffer state during write.
|
||||
|
||||
As io_flush callback is optional, if a subclass does not implement it, then:
|
||||
- io_flush will return 0 without changing anything.
|
||||
|
||||
Also, some functions like qio_channel_writev_full_all() were adapted to
|
||||
receive a flag parameter. That allows shared code between zero copy and
|
||||
non-zero copy writev, and also an easier implementation on new flags.

|
||||
|
||||
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

If flush is called when no buffer was sent with MSG_ZEROCOPY, it currently
|
||||
returns 1. This return code should be used only when Linux fails to use
|
||||
MSG_ZEROCOPY on a lot of sendmsg().
|
||||
|
||||
Fix this by returning early from flush if no sendmsg(...,MSG_ZEROCOPY)
|
||||
was attempted.

Somewhere between v6 and v7 the of the zero-copy-send patchset a crucial
|
||||
part of the flushing mechanism got missing: incrementing zero_copy_queued.
|
||||
|
||||
Without that, the flushing interface becomes a no-op, and there is no
|
||||
guarantee the buffer is really sent.
|
||||
|
||||
This can go as bad as causing a corruption in RAM during migration.

|
||||
|
||||
For CONFIG_LINUX, implement the new zero copy flag and the optional callback
|
||||
io_flush on QIOChannelSocket, but enables it only when MSG_ZEROCOPY
|
||||
feature is available in the host kernel, which is checked on
|
||||
qio_channel_socket_connect_sync()
|
||||
|
||||
qio_channel_socket_flush() was implemented by counting how many times
|
||||
sendmsg(...,MSG_ZEROCOPY) was successfully called, and then reading the
|
||||
socket's error queue, in order to find how many of them finished sending.
|
||||
Flush will loop until those counters are the same, or until some error occurs.
|
||||
|
||||
Notes on using writev() with QIO_CHANNEL_WRITE_FLAG_ZERO_COPY:
|
||||
1: Buffer
|
||||
- As MSG_ZEROCOPY tells the kernel to use the same user buffer to avoid copying,
|
||||
some caution is necessary to avoid overwriting any buffer before it's sent.
|
||||
If something like this happen, a newer version of the buffer may be sent instead.
|
||||
- If this is a problem, it's recommended to call qio_channel_flush() before freeing
|
||||
or re-using the buffer.
|
||||
|
||||
2: Locked memory
|
||||
- When using MSG_ZERCOCOPY, the buffer memory will be locked after queued, and
|
||||
unlocked after it's sent.
|
||||
- Depending on the size of each buffer, and how often it's sent, it may require
|
||||
a larger amount of locked memory than usually available to non-root user.
|
||||
- If the required amount of locked memory is not available, writev_zero_copy
|
||||
will return an error, which can abort an operation like migration,
|
||||
- Because of this, when an user code wants to add zero copy as a feature, it
|
||||
requires a mechanism to disable it, so it can still be accessible to less
|
||||
privileged users.

During implementation of MSG_ZEROCOPY feature, a lot of #ifdefs were
|
||||
introduced, particularly at qio_channel_socket_writev().
|
||||
|
||||
Rewrite some of those changes so it's easier to read.
|
||||
|
||||
Also, introduce an assert to help detect incorrect zero-copy usage is when
|
||||
it's disabled on build.

|
||||
|
||||
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.

Manual revert of commit 70d3924521c9bfd912bcf1a1fc76f49eb377de46, since
|
||||
the directory structure looks different from rhel-av-8.4.0.z where
|
||||
this commit is taken from. Besides, x86_64-softmmu.mak looks totally
|
||||
different and should not be affected by this reversal.

|
||||
accel: introduce accelerator blocker API
|
||||
|
||||
This API allows the accelerators to prevent vcpus from issuing
|
||||
new ioctls while execting a critical section marked with the
|
||||
accel_ioctl_inhibit_begin/end functions.
|
||||
|
||||
Note that all functions submitting ioctls must mark where the
|
||||
ioctl is being called with accel_{cpu_}ioctl_begin/end().
|
||||
|
||||
This API requires the caller to always hold the BQL.
|
||||
API documentation is in sysemu/accel-blocker.h
|
||||
|
||||
Internally, it uses a QemuLockCnt together with a per-CPU QemuLockCnt
|
||||
(to minimize cache line bouncing) to keep avoid that new ioctls
|
||||
run when the critical section starts, and a QemuEvent to wait
|
||||
that all running ioctls finish.

acpi: fix OEM ID/OEM Table ID padding
|
||||
|
||||
Commit [2] broke original '\0' padding of OEM ID and OEM Table ID
|
||||
fields in headers of ACPI tables. While it doesn't have impact on
|
||||
default values since QEMU uses 6 and 8 characters long values
|
||||
respectively, it broke usecase where IDs are provided on QEMU CLI.
|
||||
It shouldn't affect guest (but may cause licensing verification
|
||||
issues in guest OS).
|
||||
One of the broken usecases is user supplied SLIC table with IDs
|
||||
shorter than max possible length, where [2] mangles IDs with extra
|
||||
spaces in RSDT and FADT tables whereas guest OS expects those to
|
||||
mirror the respective values of the used SLIC table.
|
||||
|
||||
Fix it by replacing whitespace padding with '\0' padding in
|
||||
accordance with [1] and expectations of guest OS
|
||||
|
||||
1) ACPI spec, v2.0b
|
||||
17.2 AML Grammar Definition
|
||||
...
|
||||
//OEM ID of up to 6 characters. If the OEM ID is
|
||||
//shorter than 6 characters, it can be terminated
|
||||
//with a NULL character.

|

acpi: fix QEMU crash when started with SLIC table
|
||||
|
||||
if QEMU is started with used provided SLIC table blob,
|
||||
|
||||
-acpitable sig=SLIC,oem_id='CRASH ',oem_table_id="ME",oem_rev=00002210,asl_compiler_id="",asl_compiler_rev=00000000,data=/dev/null
|
||||
it will assert with:
|
||||
|
||||
hw/acpi/aml-build.c:61:build_append_padded_str: assertion failed: (len <= maxlen)
|
||||
|
||||
and following backtrace:
|
||||
|
||||
...
|
||||
build_append_padded_str (array=0x555556afe320, str=0x555556afdb2e "CRASH ME", maxlen=0x6, pad=0x20) at hw/acpi/aml-build.c:61
|
||||
acpi_table_begin (desc=0x7fffffffd1b0, array=0x555556afe320) at hw/acpi/aml-build.c:1727
|
||||
build_fadt (tbl=0x555556afe320, linker=0x555557ca3830, f=0x7fffffffd318, oem_id=0x555556afdb2e "CRASH ME", oem_table_id=0x555556afdb34 "ME") at hw/acpi/aml-build.c:2064
|
||||
...
|
||||
|
||||
which happens due to acpi_table_begin() expecting NULL terminated
|
||||
oem_id and oem_table_id strings, which is normally the case, but
|
||||
in case of user provided SLIC table, oem_id points to table's blob
|
||||
directly and as result oem_id became longer than expected.
|
||||
|
||||
Fix issue by handling oem_id consistently and make acpi_get_slic_oem()
|
||||
return NULL terminated strings.
|
||||
|
||||
PS:
|
||||
After [1] refactoring, oem_id semantics became inconsistent, where
|
||||
NULL terminated string was coming from machine and old way pointer
|
||||
into byte array coming from -acpitable option. That used to work
|
||||
since build_header() wasn't expecting NULL terminated string and
|
||||
blindly copied the 1st 6 bytes only.
|
||||
|
||||
However commit [2] broke that by replacing build_header() with
|
||||
acpi_table_begin(), which was expecting NULL terminated string
|
||||
and was checking oem_id size.
|
||||
|
||||
1) 602b45820 ("acpi: Permit OEM ID and OEM table ID fields to be changed")
|
||||
2)
|
||||
Fixes: 4b56e1e4eb08 ("acpi: build_fadt: use acpi_table_begin()/acpi_table_end() instead of build_header()")

RH-Commit: [1/2] c5b9cdf5791cd856207b7df7e2ef5df360ec8de4
|
||||
|
||||
vmstate_acpi_pcihp_use_acpi_index() was expecting AcpiPciHpState
|
||||
as state but it actually received PIIX4PMState, because
|
||||
VMSTATE_PCI_HOTPLUG is a macro and not another struct.
|
||||
So it ended up accessing random pointer, which resulted
|
||||
in 'false' return value and acpi_index field wasn't ever
|
||||
sent.
|
||||
|
||||
However in 7.0 that pointer de-references to value > 0, and
|
||||
destination QEMU starts to expect the field which isn't
|
||||
sent in migratioon stream from older QEMU (6.2 and older).
|
||||
As result migration fails with:
|
||||
qemu-system-x86_64: Missing section footer for 0000:00:01.3/piix4_pm
|
||||
qemu-system-x86_64: load of migration failed: Invalid argument
|
||||
|
||||
In addition with QEMU-6.2, destination due to not expected
|
||||
state, also never expects the acpi_index field in migration
|
||||
stream.
|
||||
|
||||
Q35 is not affected as it always sends/expects the field as
|
||||
long as acpi based PCI hotplug is enabled.
|
||||
|
||||
Fix issue by introducing compat knob to never send/expect
|
||||
acpi_index in migration stream for 6.2 and older PC machine
|
||||
types and always send it for 7.0 and newer PC machine types.

acpi: pcihp: pcie: set power on cap on parent slot
|
||||
|
||||
on creation a PCIDevice has power turned on at the end of pci_qdev_realize()
|
||||
however later on if PCIe slot isn't populated with any children
|
||||
it's power is turned off. It's fine if native hotplug is used
|
||||
as plug callback will power slot on among other things.
|
||||
However when ACPI hotplug is enabled it replaces native PCIe plug
|
||||
callbacks with ACPI specific ones (acpi_pcihp_device_*plug_cb) and
|
||||
as result slot stays powered off. It works fine as ACPI hotplug
|
||||
on guest side takes care of enumerating/initializing hotplugged
|
||||
device. But when later guest is migrated, call chain introduced by]
|
||||
commit d5daff7d312 (pcie: implement slot power control for pcie root ports)
|
||||
|
||||
pcie_cap_slot_post_load()
|
||||
-> pcie_cap_update_power()
|
||||
-> pcie_set_power_device()
|
||||
-> pci_set_power()
|
||||
-> pci_update_mappings()
|
||||
|
||||
will disable earlier initialized BARs for the hotplugged device
|
||||
in powered off slot due to commit 23786d13441 (pci: implement power state)
|
||||
which disables BARs if power is off.
|
||||
|
||||
Fix it by setting PCI_EXP_SLTCTL_PCC to PCI_EXP_SLTCTL_PWR_ON
|
||||
on slot (root port/downstream port) at the time a device
|
||||
hotplugged into it. As result PCI_EXP_SLTCTL_PWR_ON is migrated
|
||||
to target and above call chain keeps device plugged into it
|
||||
powered on.

When bus is looked up on a pci write, we didn't
|
||||
validate that the lookup succeeded.
|
||||
Fuzzers thus can trigger QEMU crash by dereferencing the NULL
|
||||
bus pointer.

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.

The barrier comes after an atomic increment, so it is enough to use

smp_mb__after_rmw(); this avoids a double barrier on x86 systems.

aio_wait_kick: add missing memory barrier
|
||||
|
||||
It seems that aio_wait_kick always required a memory barrier
|
||||
or atomic operation in the caller, but nobody actually
|
||||
took care of doing it.
|
||||
|
||||
Let's put the barrier in the function instead, and pair it
|
||||
with another one in AIO_WAIT_WHILE. Read aio_wait_kick()
|
||||
comment for further explanation.

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.

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.

Explain that aio_context_notifier_poll() relies on
|

aio_notify_accept() to catch all the memory writes that were
|

done before ctx->notified was set to true.

Ever since commit 8c6b0356b539 ("util/async: make bh_aio_poll() O(1)",

is happening when the bottom half is enqueued in the bh_list; not
|
||||
when the flags are set. Update the documentation to match.

RH-Commit: [1/1] b5a1047750af32c0a261b8385ea0e819eb16681a
|
||||
|
||||
It is currently not possible yet to use "memory-backend-memfd" on s390x
|
||||
with hugepages enabled. This problem is caused by qemu_maxrampagesize()
|
||||
not taking memory-backend-memfd objects into account yet, so the code
|
||||
in s390_memory_init() fails to enable the huge page support there via
|
||||
s390_set_max_pagesize(). Fix it by generalizing the code, so that it
|
||||
looks at qemu_ram_pagesize(memdev->mr.ram_block) instead of re-trying
|
||||
to get the information from the filesystem.

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.

RH-Commit: [2/5] 1d86ce8398e4ab66e308a686f9855c963e52b0a9
|
||||
|
||||
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.

RH-Commit: [5/5] f9188bd089d6c67185ea1accde20d491a2ed3193
|
||||
|
||||
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.

bdrv_subtree_drained_end() requires the caller to hold the AioContext
|
||||
lock for the drained node. Not doing this for nodes outside of the main
|
||||
AioContext leads to crashes when AIO_WAIT_WHILE() needs to wait and
|
||||
tries to temporarily release the lock.

|
||||
|
||||
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-MergeRequest: 109: block-backend: prevent dangling BDS pointers across aio_poll()
|
||||
RH-Commit: [1/2] da5a59eddff0dc10be7de8e291fa675143d11d73
|
||||

|
||||
|
||||
The BlockBackend root child can change when aio_poll() is invoked. This
|
||||
happens when a temporary filter node is removed upon blockjob
|
||||
completion, for example.
|
||||
|
||||
Functions in block/block-backend.c must be aware of this when using a
|
||||
blk_bs() pointer across aio_poll() because the BlockDriverState refcnt
|
||||
may reach 0, resulting in a stale pointer.
|
||||
|
||||
One example is scsi_device_purge_requests(), which calls blk_drain() to
|
||||
wait for in-flight requests to cancel. If the backup blockjob is active,
|
||||
then the BlockBackend root child is a temporary filter BDS owned by the
|
||||
blockjob. The blockjob can complete during bdrv_drained_begin() and the
|
||||
last reference to the BDS is released when the temporary filter node is
|
||||
removed. This results in a use-after-free when blk_drain() calls
|
||||
bdrv_drained_end(bs) on the dangling pointer.
|
||||
|
||||
Explicitly hold a reference to bs across block APIs that invoke
|
||||
aio_poll().

|
||||
|
||||
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.

|
||||
|
||||
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.

Subject: [PATCH 4/5] block: introduce bdrv_open_file_child() helper
|

|

RH-Author: Jon Maloy <jmaloy@redhat.com>
|

RH-MergeRequest: 5: EMBARGOED CVE-2024-4467 for rhel-8.10.z (PRDSC)
|
||||

|
||||
RH-Commit: [4/5] 9f582a9aff740eb9ec6f64bfec94854038d8545f
|
||||
|
||||
Conflicts: - copy-before-write.c::cbw_copy() is an older version than
|
||||
upstream, but introduction of the new function is
|
||||
straight-forward.
|
||||
- include/block/block-global-state.h doesn't exist in this
|
||||
code version. Adding the prototype to
|
||||
include/block/block.h instead.
|
||||
- struct BlockDriver has no field 'filtered_child_is_backing'
|
||||
We remove the corresponding assert() in the new function.

||||

|
||||
|
||||
block: introduce bdrv_open_file_child() helper
|
||||
|
||||
Almost all drivers call bdrv_open_child() similarly. Let's create a
|
||||
helper for this.
|
||||
|
||||
The only not updated drivers that call bdrv_open_child() to set
|
||||
bs->file are raw-format and snapshot-access:
|
||||
raw-format sometimes want to have filtered child but
|
||||
don't set drv->is_filter to true.
|
||||
snapshot-access wants only DATA | PRIMARY
|
||||
|
||||
Possibly we should implement drv->is_filter_func() handler, to consider
|
||||
raw-format as filter when it works as filter.. But it's another story.
|
||||
|
||||
Note also, that we decrease assignments to bs->file in code: it helps
|
||||
us restrict modifying this field in further commit.
