From fc113ecd7c99646a7ced0b99570b5927ae6d595f Mon Sep 17 00:00:00 2001
From: Miroslav Rezanina <mrezanin@redhat.com>

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-6.2.0-13.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

From 19ce5ff93ddd6b8a998348f2a5f59f603c5e11b7 Mon Sep 17 00:00:00 2001
From: Miroslav Rezanina <mrezanin@redhat.com>
Date: Fri, 12 Oct 2018 07:31:11 +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
This rebase includes changes up to qemu-kvm-6.1.0-5.el9
Rebase notes (3.1.0):
- added new configure options
Rebase notes (4.0.0):
- Added dependency to perl-Test-Harness (upstream)
- Added dependency to python3-sphinx (upstream)
- Change location of icons (upstream)
- Remove .desktop file (added upstream)
- Added qemu-trace-stap (added upstream)
- Removed elf2dmp (added upstream)
- Remove .buildinfo
- Added pvh.bin rom (added upstream)
- Added interop documentation files
- Use python module instead of qemu.py (upstream)
Rebase notes (4.1.0):
- Remove edk2 files generated by build
- Switch to rhel-8.1-candidate build target
- Remove specs documentation
- Switched from libssh2 to libssh
- Add rc0 tarball usage hacks
- Added BuildRequires for wget, rpm-build and python3-sphinx
- Removed new unpacked files
- Update configure line to use new options
Rebase notes (4.2.0):
- Disable iotest run during make check
- README renamed to README.rst (upstream)
- Removed ui-spice-app.so
- Added relevant changes from "505f7f4 redhat: Adding slirp to the exploded tree"
- Removed qemu-ga.8 install from spec file - installed by make
- Removed spapr-rtas.bin (upstream)
- Require newer SLOF (20191022)
Rebase notes (5.1.0):
- Use python3 for virtio_seg_max_adjust.py test
- Removed qemu-trace-stap shebang from spec file
- Added virtiofsd.1 (upstream)
- Use out-of-tree build
- New documentation structure (upstream)

+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

O-Subject: [PATCH RHEL7 qemu-kvm v2 2/2] vfio: cap number of devices that can be assigned
Bugzilla: 678368
RH-Acked-by: Alex Williamson <alex.williamson@redhat.com>
RH-Acked-by: Marcelo Tosatti <mtosatti@redhat.com>
RH-Acked-by: Michael S. Tsirkin <mst@redhat.com>
Go through all groups to get count of total number of devices
active to enforce limit
Reasoning from Alex for the limit(32) - Assuming 3 slots per
device, with 125 slots (number of memory slots for RHEL 7),
we can support almost 40 devices and still have few slots left
for other uses. Stepping down a bit, the number 32 arbitrarily
matches the number of slots on a PCI bus and is also a nice power
of two.
Count of slots increased to 509 later so we could increase limit
to 64 as some usecases require more than 32 devices.

- removed return value for vfio_realize (commit 1a22aca)
Merged patches (2.9.0):
- 17eb774 vfio: Use error_setg when reporting max assigned device overshoot
Merged patches (4.1.0-rc3):
- 2b89558 vfio: increase the cap on number of assigned devices to 64

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.

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

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

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

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

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.

To keep compatibility with 8.5-AV machine type we need to
turn few new options on by default:
smp_props.prefer_sockets, no_cpu_topology, no_tcg_its
TESTED: migrate from rhel-av-8.5.0 to rhel-8.6.0 and vice-versa
with upstream fix: 33a0c404fb hw/intc/arm_gicv3_its: Revert version
increments in vmstate_its

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.

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.

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

===================
qemu-kvm development
===================
qemu-kvm is maintained in a `source tree`_ rather than directly in dist-git.
This provides way to develope using regular source code structure and provides
way to generate SRPM and build using koji service. In addition, local build using
CentOS 9 Stream specific configuration.
Developers deliver all changes to source-git using merge request. Only maintainers
will be pushing changes sent to source-git to dist-git.
Each release in dist-git is tagged in the source repository so you can easily
check out the source tree for a build. The tags are in the format
name-version-release, but note release doesn't contain the dist tag since the
source can be built in different build roots (Fedora, CentOS, etc.)

qemu-kvm-tests README
=====================
The qemu-kvm-tests rpm contains tests that can be used to verify the
functionality of the installed qemu-kvm package
When installed, the files from this rpm will be arranged in the following
directory structure
tests-src/
├── README
├── scripts
│   ├── qemu.py
│   └── qmp
└── tests
├── acceptance
├── Makefile.include
└── qemu-iotests
The tests/ directory within the tests-src/ directory is setup to remain a copy
of a subset of the tests/ directory from the QEMU source tree
The avocado_qemu tests and qemu-iotests, along with files required for the
execution of the avocado_qemu tests (scripts/qemu.py and scripts/qmp/) will be
installed in a new location - /usr/lib64/qemu-kvm/tests-src/
avocado_qemu tests:
The avocado_qemu tests can be executed by running the following avocado command:
avocado run -p qemu_bin=/usr/libexec/qemu-kvm /usr/lib64/qemu-kvm/tests/acceptance/
Avocado needs to be installed separately using either pip or from source as
Avocado is not being packaged for RHEL-8.
qemu-iotests:
symlinks to corresponding binaries need to be created for QEMU_PROG,
QEMU_IO_PROG, QEMU_IMG_PROG, and QEMU_NBD_PROG before the iotests can be
executed.
The primary purpose of this package is to make these tests available to be
executed as gating tests for the virt module in the RHEL-8 OSCI environment.

Subject: [PATCH 01/16] Introduce event-loop-base abstract class
RH-Author: Nicolas Saenz Julienne <nsaenzju@redhat.com>
RH-MergeRequest: 93: util/thread-pool: Expose minimum and maximum size
RH-Commit: [1/3] 5817205d8f56cc4aa98bd5963ecac54a59bad990

Introduce the 'event-loop-base' abstract class, it'll hold the
properties common to all event loops and provide the necessary hooks for
their creation and maintenance. Then have iothread inherit from it.
EventLoopBaseClass is defined as user creatable and provides a hook for
its children to attach themselves to the user creatable class 'complete'
function. It also provides an update_params() callback to propagate
property changes onto its children.
The new 'event-loop-base' class will live in the root directory. It is
built on its own using the 'link_whole' option (there are no direct
function dependencies between the class and its children, it all happens
trough 'constructor' magic). And also imposes new compilation
dependencies:
qom <- event-loop-base <- blockdev (iothread.c)
And in subsequent patches:
qom <- event-loop-base <- qemuutil (util/main-loop.c)
All this forced some amount of reordering in meson.build:
- Moved qom build definition before qemuutil. Doing it the other way
around (i.e. moving qemuutil after qom) isn't possible as a lot of
core libraries that live in between the two depend on it.
- Process the 'hw' subdir earlier, as it introduces files into the
'qom' source set.
No functional changes intended.

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.

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.

Subject: [PATCH 09/18] QIOChannelSocket: Implement io_writev zero copy flag &
io_flush for CONFIG_LINUX

RH-MergeRequest: 95: MSG_ZEROCOPY + Multifd
RH-Commit: [3/11] 9afeac1f5ac7675624660a0281726c09c8321180 (LeoBras/centos-qemu-kvm)
RH-Bugzilla: 1968509

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.

Upstream Status: RHEL only
We only need to support AArch64 cpu types and we only need three
types:
1) A base type to use with TCG, i.e. a cpu type with only base
features. 'cortex-a57' serves this role and is currently used
by libguestfs.
2) The 'max' type, which is for both KVM and TCG and is good for
tests that just specify 'max' but run under both. 'max' with
TCG also provides the VM with all the CPU features TCG
supports, which is good for VMs that need features not
provided by the basic cortex-a57.
3) The host type which is used with KVM.

Upstream Status: RHEL only
We plan to remove the cortex-a53 from the supported cpu types. Switch
all avocado tests that use it to the cortex-a57, which will work the
same and we intend to keep. We don't want to try and upstream this
change since the better upstream change would be to switch from the
a53 to 'max', but the upstream tests also need to use later guest
kernels to use 'max' (see qemu upstream commit 0942820408dc
("hw/arm/virt: Disable LPA2 for -machine virt-6.2")

Upstream Status: RHEL-only
Tested: with upstream kernel
Downstream QEMU carries a patch that sets the hard limit of possible vCPUs
to the value that the KVM code of the kernel recommends as soft limit.
Upstream KVM code has been changed recently to not use an arbitrary soft
limit anymore, but to cap the value on the amount of available physical
CPUs of the host. This defeats the purpose of the downstream change in
QEMU completely. Drop the downstream-only patch to allow CPU overcommit.
This reverts commit 6669f6fa677d43144f39d6ad59725b7ba622f1c2.

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

Over time AioContext usage and coverage has increased, and now block
backend is capable of handling AioContext change upon eject and insert.
Therefore the above downstream-only commit is not necessary anymore,

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.
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()")

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.

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.

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().

We update the block-status cache whenever we get new information from a
bdrv_co_block_status() call to the block driver. However, if we have
passed want_zero=false to that call, it may flag areas containing zeroes
as data, and so we would update the block-status cache with wrong
information.
Therefore, we should not update the cache with want_zero=false.

Our two timers must not remain armed beyond nbd_clear_bdrvstate(), or
they will access freed data when they fire.
This patch is separate from the patches that actually fix the issue

We start the reconnect delay timer to cancel the reconnection attempt
after a while. Once nbd_co_do_establish_connection() has returned, this
attempt is over, and we no longer need the timer.
Delete it before returning from nbd_reconnect_attempt(), so that it does
not persist beyond the I/O request that was paused for reconnecting; we
do not want it to fire in a drained section, because all sort of things
can happen in such a section (e.g. the AioContext might be changed, and
we do not want the timer to fire in the wrong context; or the BDS might
even be deleted, and so the timer CB would access already-freed data).

the assumption that we can't hit a hole if we do not diff against a snapshot was wrong.
We can see a hole in an image if we diff against base if there exists an older snapshot
of the image and we have discarded blocks in the image where the snapshot has data.
Fix this by simply handling a hole like an unallocated area. There are no callbacks
for unallocated areas so just bail out if we hit a hole.

librbd had a bug until early 2022 that affected all versions of ceph that
supported fast-diff. This bug results in reporting of incorrect offsets
if the offset parameter to rbd_diff_iterate2 is not object aligned.
This patch works around this bug for pre Quincy versions of librbd.

It's true that these functions currently affect the batch size in which
coroutines are reused (i.e. moved from the global release pool to the
allocation pool of a specific thread), but this is a bug and will be
fixed in a separate patch.
In fact, the comment in the header file already just promises that it
influences the pool size, so reflect this in the name of the functions.
As a nice side effect, the shorter function name makes some line
wrapping unnecessary.

RH-Commit: [2/2] 8a8a39af873854cdc8333d1a70f3479a97c3ec7a (kmwolf/centos-qemu-kvm)

Commit 4c41c69e changed the way the coroutine pool is sized because for
virtio-blk devices with a large queue size and heavy I/O, it was just
too small and caused coroutines to be deleted and reallocated soon
afterwards. The change made the size dynamic based on the number of
queues and the queue size of virtio-blk devices.
There are two important numbers here: Slightly simplified, when a
coroutine terminates, it is generally stored in the global release pool
up to a certain pool size, and if the pool is full, it is freed.
Conversely, when allocating a new coroutine, the coroutines in the
release pool are reused if the pool already has reached a certain
minimum size (the batch size), otherwise we allocate new coroutines.
The problem after commit 4c41c69e is that it not only increases the
maximum pool size (which is the intended effect), but also the batch
size for reusing coroutines (which is a bug). It means that in cases
with many devices and/or a large queue size (which defaults to the
number of vcpus for virtio-blk-pci), many thousand coroutines could be
sitting in the release pool without being reused.
This is not only a waste of memory and allocations, but it actually
makes the QEMU process likely to hit the vm.max_map_count limit on Linux
because each coroutine requires two mappings (its stack and the guard
page for the stack), causing it to abort() in qemu_alloc_stack() because
when the limit is hit, mprotect() starts to fail with ENOMEM.
In order to fix the problem, change the batch size back to 64 to avoid
uselessly accumulating coroutines in the release pool, but keep the
dynamic maximum pool size so that coroutines aren't freed too early
in heavy I/O scenarios.
Note that this fix doesn't strictly make it impossible to hit the limit,
but this would only happen if most of the coroutines are actually in use
at the same time, not just sitting in a pool. This is the same behaviour
as we already had before commit 4c41c69e. Fully preventing this would
require allowing qemu_coroutine_create() to return an error, but it
doesn't seem to be a scenario that people hit in practice.

another thread the TLS variables from the old thread must no longer be
used.
Use QEMU_DEFINE_STATIC_CO_TLS() for the current and leader variables.
The alloc_pool QSLIST needs a typedef so the return value of
get_ptr_alloc_pool() can be stored in a local variable.
One example of why this code is necessary: a coroutine that yields
before calling qemu_coroutine_create() to create another coroutine is
affected by the TLS issue.

I think coroutine-win32.c could get away with __thread because the
variables are only used in situations where either the stale value is
correct (current) or outside coroutine context (loading leader when
current is NULL). Due to the difficulty of being sure that this is
really safe in all scenarios it seems worth converting it anyway.

PPTT table
RH-Author: Gavin Shan <gshan@redhat.com>
RH-MergeRequest: 86: hw/arm/virt: Fix the default CPU topology
RH-Commit: [6/6] 53fa376531c204cf706cc1a7a0499019756106cb (gwshan/qemu-rhel-9)

When the PPTT table is built, the CPU topology is re-calculated, but
it's unecessary because the CPU topology has been populated in
virt_possible_cpu_arch_ids() on arm/virt machine.
This reworks build_pptt() to avoid by reusing the existing IDs in
ms->possible_cpus. Currently, the only user of build_pptt() is
arm/virt machine.

Truly allow TCG ITS instantiation according to the no_tcg_its

We also take benefit of this patch to do some minor non

Currently, the SMP configuration isn't considered when the CPU
topology is populated. In this case, it's impossible to provide
the default CPU-to-NUMA mapping or association based on the socket
ID of the given CPU.
This takes account of SMP configuration when the CPU topology
is populated. The die ID for the given CPU isn't assigned since
it's not supported on arm/virt machine. Besides, the used SMP
configuration in qtest/numa-test/aarch64_numa_cpu() is corrcted
to avoid testing failure

When CPU-to-NUMA association isn't explicitly provided by users,
the default one is given by mc->get_default_cpu_node_id(). However,
the CPU topology isn't fully considered in the default association
and this causes CPU topology broken warnings on booting Linux guest.
For example, the following warning messages are observed when the
Linux guest is booted with the following command lines.

BUG: arch topology borken
the DIE domain not a subset of the NODE domain
With current implementation of mc->get_default_cpu_node_id(),
CPU#0 to CPU#5 are associated with NODE#0 to NODE#5 separately.
That's incorrect because CPU#0/1/2 should be associated with same
NUMA node because they're seated in same socket.
This fixes the issue by considering the socket ID when the default
CPU-to-NUMA association is provided in virt_possible_cpu_arch_ids().
With this applied, no more CPU topology broken warnings are seen
from the Linux guest. The 6 CPUs are associated with NODE#0/1, but
there are no CPUs associated with NODE#2/3/4/5.

Brew: https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=45133161
Upstream Status: RHEL-only
Tested: Boot RHEL guest and check migration from 8.6 to 9.1
(with custom additions)
During the 7.0 rebase, the initialization of highmem_mmio and
highmem_redists was forgotten in rhel_virt_instance_init().
Fix it to match virt_instance_init() code.
Also mc->smp_props.clusters_supported was missing in
rhel_machine_class_init().

Upstream: no
Register the "iommu" option as a class property. This mirrors what
was done in upstream commit b91def7b ("arm/virt: Register
most properties as class properties").
While we are at it we also move the "x-oem-id" and "x-oem-table-id"
registrations at the very end of the rhel_machine_class_init()
function. This makes our life easier when comparing with upstream.
