From cbd36e2ba7f3e96ce441c7cfbf92017a7ba3bfe8 Mon Sep 17 00:00:00 2001
From: Miroslav Rezanina <mrezanin@redhat.com>
Date: Wed, 26 May 2021 10:56:02 +0200
Subject: Initial redhat build
This patch introduces redhat build structure in redhat subdirectory. In addition,
several issues are fixed in QEMU tree:
- Change of app name for sasl_server_init in VNC code from qemu to qemu-kvm
- As we use qemu-kvm as name in all places, this is updated to be consistent
- Man page renamed from qemu to qemu-kvm
- man page is installed using make install so we have to fix it in qemu tree
We disable make check due to issues with some of the tests.
This rebase is based on qemu-kvm-9.0.0-10.el9

+QEMU tracing using systemtap-initscript
+---------------------------------------
+
+You can capture QEMU trace data all the time using systemtap-initscript. This
+uses SystemTap's flight recorder mode to trace all running guests to a
+fixed-size buffer on the host. Old trace entries are overwritten by new
+entries when the buffer size wraps.
+
+1. Install the systemtap-initscript package:
+ # yum install systemtap-initscript
+
+2. Install the systemtap scripts and the conf file:
+ # cp /usr/share/qemu-kvm/systemtap/script.d/qemu_kvm.stp /etc/systemtap/script.d/
+ # cp /usr/share/qemu-kvm/systemtap/conf.d/qemu_kvm.conf /etc/systemtap/conf.d/
+
+The set of trace events to enable is given in qemu_kvm.stp. This SystemTap
+script can be customized to add or remove trace events provided in
+/usr/share/systemtap/tapset/qemu-kvm-simpletrace.stp.
+
+SystemTap customizations can be made to qemu_kvm.conf to control the flight
+recorder buffer size and whether to store traces in memory only or disk too.
+See stap(1) for option documentation.
+
+3. Start the systemtap service.
+ # service systemtap start qemu_kvm
+
+4. Make the service start at boot time.
+ # chkconfig systemtap on
+
+5. Confirm that the service works.
+ # service systemtap status qemu_kvm
+ qemu_kvm is running...
+
+When you want to inspect the trace buffer, perform the following steps:
+
+1. Dump the trace buffer.
+ # staprun -A qemu_kvm >/tmp/trace.log
+
+2. Start the systemtap service because the preceding step stops the service.
+ # service systemtap start qemu_kvm
+
+3. Translate the trace record to readable format.
+ # /usr/share/qemu-kvm/simpletrace.py --no-header /usr/share/qemu-kvm/trace-events /tmp/trace.log

+QEMU tracing using systemtap-initscript
+---------------------------------------
+
+You can capture QEMU trace data all the time using systemtap-initscript. This
+uses SystemTap's flight recorder mode to trace all running guests to a
+fixed-size buffer on the host. Old trace entries are overwritten by new
+entries when the buffer size wraps.
+
+1. Install the systemtap-initscript package:
+ # yum install systemtap-initscript
+
+2. Install the systemtap scripts and the conf file:
+ # cp /usr/share/qemu-kvm/systemtap/script.d/qemu_kvm.stp /etc/systemtap/script.d/
+ # cp /usr/share/qemu-kvm/systemtap/conf.d/qemu_kvm.conf /etc/systemtap/conf.d/
+
+The set of trace events to enable is given in qemu_kvm.stp. This SystemTap
+script can be customized to add or remove trace events provided in
+/usr/share/systemtap/tapset/qemu-kvm-simpletrace.stp.
+
+SystemTap customizations can be made to qemu_kvm.conf to control the flight
+recorder buffer size and whether to store traces in memory only or disk too.
+See stap(1) for option documentation.
+
+3. Start the systemtap service.
+ # service systemtap start qemu_kvm
+
+4. Make the service start at boot time.
+ # chkconfig systemtap on
+
+5. Confirm that the service works.
+ # service systemtap status qemu_kvm
+ qemu_kvm is running...
+
+When you want to inspect the trace buffer, perform the following steps:
+
+1. Dump the trace buffer.
+ # staprun -A qemu_kvm >/tmp/trace.log
+
+2. Start the systemtap service because the preceding step stops the service.
+ # service systemtap start qemu_kvm
+
+3. Translate the trace record to readable format.
+ # /usr/share/qemu-kvm/simpletrace.py --no-header /usr/share/qemu-kvm/trace-events /tmp/trace.log

Subject: meson: temporarily disable -Wunused-function
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Deleting the upstream versioned machine types will leave some functions
unused until RHEL machine types are added once again. Temporarily
disable the -Wunused-function warning to preserve bisectability with
fine grained patch splits.

Subject: Adapt versioned machine type macros for RHEL
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The versioned machine type macros are changed thus:
* All symbol names get 'rhel' inserted eg 'virt_rhel_macine_9_4_0_<blah>'
* All machine type names get 'rhel' inserted eg 'virt-rhel9.4.0-machine'
* Lifecycle is changed to deprecate after 1 major RHEL release,
force non-registration (effectively deletion) after 2 major releases
* Custom message to explain RHEL deprecation/deletion policy
* Remove upstream logic that temporarily disabled deletion since
the upstream constraints in this area don't apply to RHEL
* For automatic deprecation/deletion, RHEL_VERSION is defined

The RHEL-9 series still keeps the rhel 7.6.0 machine types as a
special exception to our normal rule of deleting machine types
after 2 releases. The exception will go away in RHEL-10.

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.

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.

RH-Acked-by: Serhii Popovych <spopovyc@redhat.com>
RH-Acked-by: Thomas Huth <thuth@redhat.com>
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

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.

Subject: Fix virtio-net-pci* "vectors" compat

RH-MergeRequest: 77: 8.6/6.2 mt fixes
RH-Commit: [21/23] 8ad581932275d2698a99f31bec40b14f1dbd3d2e

hw_compat_rhel_8_4 has an issue: it affects only "virtio-net-pci"
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.

Subject: x86/rhel machine types: Add pc_rhel_8_5_compat
RH-Author: Dr. David Alan Gilbert <dgilbert@redhat.com>
RH-MergeRequest: 77: 8.6/6.2 mt fixes
RH-Commit: [22/23] 8bf555c5d78f344b97ffd5c888c7a7bed592d9d0
RH-Bugzilla: 2026443
RH-Acked-by: Miroslav Rezanina <mrezanin@redhat.com>
Add pc_rhel_8_5_compat as the merge of pc_compat_6_1 and pc_compat_6_0
(since 8.5 was based on 6.0).
Note, x-keep-pci-slot-hpc flipped back and forward, leaving it out
looks like it leaves us with the original.

Subject: redhat: Add QEMU 9.1 compat handling to the s390x machine types
JIRA: https://issues.redhat.com/browse/RHEL-52323
Upstream changed the amount of information that is migrated for
the S390 interrupt controller (FLIC), so we have to switch on
a compatibility property for older machine types.

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

Subject: hw/arm/virt: Fix Manufacturer and Product Name in emulated SMBIOS
mode
Status: RHEL-only
In vm, when run 'dmidecode -t system', it outputs different Manufacturer
and Product Name on x86_64 and aarch64 system. For example:
For aarch64 vm:
Manufacturer: QEMU
Product Name: KVM Virtual Machine
For x86_64 vm:
Manufacturer: Red Hat
Product Name: KVM
Fixing this issue by changing Manufacturer to 'Red Hat' and Product
Name to 'KVM' on aarch64 platform. Thus the output is aligned on both
x86_64 and aarch64 platform.
To keep the compatability, this only apply for the RHEL9.6 machine
type. For RHEL9.4 machine type, it still keep the old Manufacturer and
Product Name.

Zhiyi reported an infinite loop issue in VFIO use case. The cause of that
was a separate discussion, however during that I found a regression of
dirty sync slowness when profiling.
Each KVMMemoryListerner maintains an array of kvm memslots. Currently it's
statically allocated to be the max supported by the kernel. However after
Linux commit 4fc096a99e ("KVM: Raise the maximum number of user memslots"),
the max supported memslots reported now grows to some number large enough
so that it may not be wise to always statically allocate with the max
reported.
What's worse, QEMU kvm code still walks all the allocated memslots entries
to do any form of lookups. It can drastically slow down all memslot
operations because each of such loop can run over 32K times on the new
kernels.
Fix this issue by making the memslots to be allocated dynamically.
Here the initial size was set to 16 because it should cover the basic VM
usages, so that the hope is the majority VM use case may not even need to
grow at all (e.g. if one starts a VM with ./qemu-system-x86_64 by default
it'll consume 9 memslots), however not too large to waste memory.
There can also be even better way to address this, but so far this is the
simplest and should be already better even than before we grow the max
supported memslots. For example, in the case of above issue when VFIO was
attached on a 32GB system, there are only ~10 memslots used. So it could
be good enough as of now.
In the above VFIO context, measurement shows that the precopy dirty sync
shrinked from ~86ms to ~3ms after this patch applied. It should also apply
to any KVM enabled VM even without VFIO.
NOTE: we don't have a FIXES tag for this patch because there's no real
commit that regressed this in QEMU. Such behavior existed for a long time,
but only start to be a problem when the kernel reports very large
nr_slots_max value. However that's pretty common now (the kernel change
was merged in 2021) so we attached cc:stable because we'll want this change
to be backported to stable branches.

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.

Subject: [PATCH 13/24] KVM: x86: workaround invalid CPUID[0xD,9] info on some
AMD processors
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
RH-Author: Paul Lai <plai@redhat.com>
RH-MergeRequest: 176: Enable KVM AMX support
RH-Commit: [13/13] 38f147c911258e84e01336271ebd23a1c24371fc
RH-Bugzilla: 1916415
RH-Acked-by: Cornelia Huck <cohuck@redhat.com>
RH-Acked-by: Igor Mammedov <imammedo@redhat.com>
RH-Acked-by: Paolo Bonzini <pbonzini@redhat.com>
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.

vhost-vsock device in RHEL 8 kernels doesn't support seqpacket.
To avoid problems when migrating a VM from RHEL 9 host, we need to
disable it in rhel8-* machine types.

Upstream: no
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.

commit bd688fc93120fb3e28aa70e3dfdf567ccc1e0bc1
Author: Emanuele Giuseppe Esposito <eesposit@redhat.com>
Date: Fri Nov 11 10:47:56 2022 -0500
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.

Author: Igor Mammedov <imammedo@redhat.com>
Date: Mon Dec 27 14:31:17 2021 -0500
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.

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

Fuzzers thus can trigger QEMU crash by dereferencing the NULL

aio-wait: switch to smp_mb__after_rmw()
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.

RHEL9 kernels have pauth disabled while RHEL10 has it enabled,
since qemu will setup the VM/VCPU with pauth when KVM supports it
the guest visible ID registers will change when a RHEL9 qemu is
used on a RHEL10 kernel (e.g. in a container on a host with pauth
support).
Make sure that virt-rhel9* machine types in RHEL9 stay the same
independent of the kernel.

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1999236
Upstream: Merged
CVE: CVE-2021-3750
Conflict: The file block/graph-lock.h, inluded from include/block/aio.h,
doesn't exist in this code version. The code compiles without
issues if this include is just omitted, so we do that.
commit 9c86c97f12c060bf7484dd931f38634e166a81f0
Author: Alexander Bulekov <alxndr@bu.edu>

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.

2020-02-22), synchronization between qemu_bh_schedule() and aio_bh_poll()

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.

bcm2835_property: disable reentrancy detection for iomem
As the code is designed for re-entrant calls from bcm2835_property to
bcm2835_mbox and back into bcm2835_property, mark iomem as
reentrancy-safe.

Subject: [PATCH 15/23] block: Add blockdev-set-active QMP command
RH-Author: Kevin Wolf <kwolf@redhat.com>
RH-MergeRequest: 339: QMP command for block device reactivation after migration
RH-Jira: RHEL-54296 RHEL-78397
RH-Acked-by: Eric Blake <eblake@redhat.com>

RH-Commit: [14/22] e494fb6df6c363b6266e5fb7d09c31b3e7694f04 (kmwolf/centos-qemu-kvm)
The system emulator tries to automatically activate and inactivate block
nodes at the right point during migration. However, there are still
cases where it's necessary that the user can do this manually.
Images are only activated on the destination VM of a migration when the
VM is actually resumed. If the VM was paused, this doesn't happen
automatically. The user may want to perform some operation on a block
device (e.g. taking a snapshot or starting a block job) without also
resuming the VM yet. This is an example where a manual command is
necessary.
Another example is VM migration when the image files are opened by an
external qemu-storage-daemon instance on each side. In this case, the
process that needs to hand over the images isn't even part of the
migration and can't know when the migration completes. Management tools
need a way to explicitly inactivate images on the source and activate
them on the destination.
This adds a new blockdev-set-active QMP command that lets the user
change the status of individual nodes (this is necessary in
qemu-storage-daemon because it could be serving multiple VMs and only
one of them migrates at a time). For convenience, operating on all
devices (like QEMU does automatically during migration) is offered as an
option, too, and can be used in the context of single VM.

Subject: [PATCH 14/23] block: Add option to create inactive nodes

RH-MergeRequest: 339: QMP command for block device reactivation after migration

RH-Commit: [13/22] 45b01b9c09d5f12715e4977cab6140d2cac90714 (kmwolf/centos-qemu-kvm)
In QEMU, nodes are automatically created inactive while expecting an
incoming migration (i.e. RUN_STATE_INMIGRATE). In qemu-storage-daemon,
the notion of runstates doesn't exist. It also wouldn't necessarily make
sense to introduce it because a single daemon can serve multiple VMs
that can be in different states.
Therefore, allow the user to explicitly open images as inactive with a
new option. The default is as before: Nodes are usually active, except
when created during RUN_STATE_INMIGRATE.

RH-Commit: [8/22] 781a749ae61e038b5b562407b01d53a1bfba598c (kmwolf/centos-qemu-kvm)
What we wanted to catch with the assertion is cases where the recursion
finds that a child was inactive before its parent. This should never
happen. But if the user tries to inactivate an image that is already
inactive, that's harmless and we don't want to fail the assertion.
