From 431955e872aa010376b1f94665908c2ba8194b44 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
We disable make check due to issues with some of the tests.
This rebase is based on qemu-kvm-5.2.0-16.el9
Signed-off-by: Miroslav Rezanina <mrezanin@redhat.com>

+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>

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.

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.

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

x-blockdev-reopen is still considered unstable upstream. libvirt needs
(a small subset of) it for incremental backups, though.
Add a downstream-only feature flag that effectively makes this a
versioned interface. As long as the feature is present, we promise that
we won't change the interface incompatibly. Incompatible changes to the
command will require us to drop the feature flag (and possibly introduce
a new one if the new version is still not stable upstream).

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 04/39] Remove RHEL 7.1.0 machine type
RH-Author: quintela1 <quintela@redhat.com>
RH-MergeRequest: 30: Remove RHEL 7.x.0 machine types
RH-Commit: [2/6] af1d8896d63756d1acc5af8658465808c4a13ca3 (juan.quintela/qemu-kvm)
RH-Bugzilla: 1968519
RH-Acked-by: Cornelia Huck <cohuck@redhat.com>
RH-Acked-by: Thomas Huth <thuth@redhat.com>
RH-Acked-by: Miroslav Rezanina <mrezanin@redhat.com>
migrate_pre_2_2 was a redhat artifact, removed.
broken_reserved_end is already fixed, nothing to do.

There's no reason not to support these devices and doing so allows us
to match x86 and ppc. Also to match the other architectures we do not
enable CONFIG_USB_STORAGE_BOT, as that was disabled for the other
architectures for BZ1866133.

We want to enable the PVPANIC facility on ARM. On aarch64,
the PVPANIC PCI device is used (on x86_64 the ISA device is used).
so let's set the PVPANIC_PCI config.

Commit [1] moved _SUN variable from only hot-pluggable to
all devices. This made linux kernel enumerate extra slots
that weren't present before. If extra slot happens to be
be enumerated first and there is a device in th same slot
but on other bridge, linux kernel will add -N suffix to
slot name of the later, thus changing NIC name compared to
QEMU 5.2. This in some case confuses systemd, if it is
using SLOT NIC naming scheme and interface name becomes
not the same as it was under QEMU-5.2.
Reproducer QEMU CLI:
-M pc-i440fx-5.2 -nodefaults \
-device pci-bridge,chassis_nr=1,id=pci.1,bus=pci.0,addr=0x3 \
-device virtio-net-pci,id=nic1,bus=pci.1,addr=0x1 \
-device virtio-net-pci,id=nic2,bus=pci.1,addr=0x2 \
-device virtio-net-pci,id=nic3,bus=pci.1,addr=0x3
with RHEL8 guest produces following results:
v5.2:
kernel: virtio_net virtio0 ens1: renamed from eth0
kernel: virtio_net virtio2 ens3: renamed from eth2
kernel: virtio_net virtio1 enp1s2: renamed from eth1
(slot 2 is assigned to empty bus 0 slot and virtio1
is assigned to 2-2 slot, and renaming falls back,
for some reason, to path based naming scheme)
v6.0:
kernel: virtio_net virtio0 ens1: renamed from eth0
kernel: virtio_net virtio2 ens3: renamed from eth2
systemd-udevd[299]: Error changing net interface name 'eth1' to 'ens3': File exists
systemd-udevd[299]: could not rename interface '3' from 'eth1' to 'ens3': File exists
(with commit [1] kernel assigns virtio2 to 3-2 slot
since bridge advertises _SUN=0x3 and kernel assigns
slot 3 to bridge. Still it manages to rename virtio2
correctly to ens3, however systemd gets confused with virtio1
where slot allocation exactly the same (2-2) as in 5.2 case
and tries to rename it to ens3 which is rightfully taken by
virtio2)
I'm not sure what breaks in systemd interface renaming (it probably
should be investigated), but on QEMU side we can safely revert
_SUN to 5.2 behavior (i.e. avoid cold-plugged bridges and non
hot-pluggable device classes), without breaking acpi-index, which uses
slot numbers but it doesn't have to use _SUN, it could use an arbitrary
variable name that has the same slot value).
It will help existing VMs to keep networking with non trivial
configs in working order since systemd will do its interface
renaming magic as it used to do.

The audio migration vmstate is empty, and always has been; we can't
just remove it though because an old qemu might send it us.
Changes with -audiodev now mean it's sometimes created when it didn't
used to be, and can confuse migration to old qemu.
Change it so that vmstate_audio is never sent; if it's received it
should still be accepted, and old qemu's shouldn't be too upset if it's
missing.

Currently, the block driver whitelists are only applied for the system
emulator. All other binaries still give unrestricted access to all block
drivers. There are use cases where this made sense because the main
concern was avoiding customers running VMs on less optimised block
drivers and getting bad performance. Allowing the same image format e.g.
as a target for 'qemu-img convert' is not a problem then.
However, if the concern is the supportability of the driver in general,
either in full or when used read-write, not applying the list driver
whitelist in tools doesn't help - especially since qemu-nbd and
qemu-storage-daemon now give access to more or less the same operations
in block drivers as running a system emulator.
In order to address this, introduce a new configure option that enforces
the driver whitelist in all binaries.

When bdrv_pad_request() fails in bdrv_co_preadv_part(), bs->in_flight
has been increased, but is never decreased again. This leads to a hang
when trying to drain the block node.
This bug was observed with Windows guests which issue a request that
fully uses IOV_MAX during installation, so that when padding is
necessary (O_DIRECT with a 4k sector size block device on the host),
adding another entry causes failure.
Call bdrv_dec_in_flight() to fix this. There is a larger problem to
solve here because this request shouldn't even fail, but Windows doesn't
seem to care and with this minimal fix the installation succeeds. So
given that we're already in freeze, let's take this minimal fix for 6.1.

Subject: [PATCH 17/43] block: add max_hw_transfer to BlockLimits
RH-Author: Miroslav Rezanina <mrezanin@redhat.com>
RH-Bugzilla: 1957194
For block host devices, I/O can happen through either the kernel file
descriptor I/O system calls (preadv/pwritev, io_submit, io_uring)
or the SCSI passthrough ioctl SG_IO.
In the latter case, the size of each transfer can be limited by the
HBA, while for file descriptor I/O the kernel is able to split and
merge I/O in smaller pieces as needed. Applying the HBA limits to
file descriptor I/O results in more system calls and suboptimal
performance, so this patch splits the max_transfer limit in two:
max_transfer remains valid and is used in general, while max_hw_transfer
is limited to the maximum hardware size. max_hw_transfer can then be
included by the scsi-generic driver in the block limits page, to ensure
that the stricter hardware limit is used.

Allow block backends to poll their devices/users to check if they have
been quiesced when entering a drained section.
This will be used in the next patch to wait for the NBD server to be
completely quiesced.

Subject: [PATCH 16/43] block-backend: align max_transfer to request alignment
RH-Author: Miroslav Rezanina <mrezanin@redhat.com>
RH-Bugzilla: 1957194
Block device requests must be aligned to bs->bl.request_alignment.
It makes sense for drivers to align bs->bl.max_transfer the same
way; however when there is no specified limit, blk_get_max_transfer
just returns INT_MAX. Since the contract of the function does not
specify that INT_MAX means "no maximum", just align the outcome
of the function (whether INT_MAX or bs->bl.max_transfer) before
returning it.

When the NVMe block driver was introduced (see commit bdd6a90a9e5,
January 2018), Linux VFIO_IOMMU_MAP_DMA ioctl was only returning
-ENOMEM in case of error. The driver was correctly handling the
error path to recycle its volatile IOVA mappings.
To fix CVE-2019-3882, Linux commit 492855939bdb ("vfio/type1: Limit
DMA mappings per container", April 2019) added the -ENOSPC error to
signal the user exhausted the DMA mappings available for a container.
The block driver started to mis-behave:
qemu-system-x86_64: VFIO_MAP_DMA failed: No space left on device
(qemu)
(qemu) info status
VM status: paused (io-error)
(qemu) c
VFIO_MAP_DMA failed: No space left on device
(qemu) c
VFIO_MAP_DMA failed: No space left on device
(The VM is not resumable from here, hence stuck.)
Fix by handling the new -ENOSPC error (when DMA mappings are
exhausted) without any distinction to the current -ENOMEM error,
so we don't change the behavior on old kernels where the CVE-2019-3882
fix is not present.
An easy way to reproduce this bug is to restrict the DMA mapping
limit (65535 by default) when loading the VFIO IOMMU module:
# modprobe vfio_iommu_type1 dma_entry_limit=666

If a user is trying to compile QEMU with link-time optimization
enabled by running the configure script like this:
.../configure --extra-cflags="-flto"
then the endianess test is failing since the magic values do not
show up in the intermediate object files there. If the host is
a big endian machine (like s390x), the QEMU binary is then unusable
since the corresponding variable "bigendian" is pre-initialized
with "no".
To fix this issue, we should rather create a full binary and look
for the magic strings there instead.
And we really should not continue the build if the endianess check
failed, to make it clear right from the start that something went
wrong here, thus let's also add some "exit 1" statements here
after emitting the error message.

Subject: [PATCH 13/43] file-posix: fix max_iov for /dev/sg devices
RH-Author: Miroslav Rezanina <mrezanin@redhat.com>
RH-Bugzilla: 1957194
Even though it was only called for devices that have bs->sg set (which
must be character devices), sg_get_max_segments looked at /sys/dev/block
which only works for block devices.
On Linux the sg driver has its own way to provide the maximum number of
iovecs in a scatter/gather list, so add support for it. The block device
path is kept because it will be reinstated in the next patches.

round to power of 2
RH-Author: Miroslav Rezanina <mrezanin@redhat.com>
RH-Bugzilla: 1957194
bs->sg is only true for character devices, but block devices can also
be used with scsi-block and scsi-generic. Unfortunately BLKSECTGET
returns bytes in an int for /dev/sgN devices, and sectors in a short
for block devices, so account for that in the code.
The maximum transfer also need not be a power of 2 (for example I have
seen disks with 1280 KiB maximum transfer) so there's no need to pass
the result through pow2floor.

Commit f61fe11aa6f broke hmp_loadvm() by adding an incorrect negation
when converting from 0/-errno return values to a bool value. The result
is that loadvm resumes the VM now if it failed and keeps it stopped if
it failed. Fix it to restore the old behaviour and do it the other way
around.

6d9cd115b9 ("hw/arm/smmuv3: Enforce invalidation on a power of two range")
failed to completely fix misalignment issues with range
invalidation. For instance invalidations patterns like "invalidate 32
4kB pages starting from 0xff395000 are not correctly handled" due
to the fact the previous fix only made sure the number of invalidated
pages were a power of 2 but did not properly handle the start
address was not aligned with the range. This can be noticed when
boothing a fedora 33 with protected virtio-blk-pci.

Disable PL011 clock migration for machine types before
virt-rhel8.4.0.
The regression was introduced by aac63e0e6ea3
("hw/char/pl011: add a clock input"), in 8.4,
causing failure of migration between qemu 8.4 towards
older ones.
The fix was taken in 8.5 as part of the rebase,
e6fa978d8343 ("hw/arm/virt: Disable pl011 clock migration
if needed"). But the compat needs to be applied in
hw_compat_rhel_8_3[].

A bus lock is acquired through either split locked access to writeback
(WB) memory or any locked access to non-WB memory. It is typically >1000
cycles slower than an atomic operation within a cache and can also
disrupts performance on other cores.
Virtual Machines can exploit bus locks to degrade the performance of
system. To address this kind of performance DOS attack coming from the
VMs, bus lock VM exit is introduced in KVM and it can report the bus
locks detected in guest. If enabled in KVM, it would exit to the
userspace to let the user enforce throttling policies once bus locks
acquired in VMs.
The availability of bus lock VM exit can be detected through the
KVM_CAP_X86_BUS_LOCK_EXIT. The returned bitmap contains the potential
policies supported by KVM. The field KVM_BUS_LOCK_DETECTION_EXIT in
bitmap is the only supported strategy at present. It indicates that KVM
will exit to userspace to handle the bus locks.
This patch adds a ratelimit on the bus locks acquired in guest as a
mitigation policy.
Introduce a new field "bus_lock_ratelimit" to record the limited speed
of bus locks in the target VM. The user can specify it through the
"bus-lock-ratelimit" as a machine property. In current implementation,
the default value of the speed is 0 per second, which means no
restrictions on the bus locks.
As for ratelimit on detected bus locks, simply set the ratelimit
interval to 1s and restrict the quota of bus lock occurence to the value
of "bus_lock_ratelimit". A potential alternative is to introduce the
time slice as a property which can help the user achieve more precise
control.
The detail of bus lock VM exit can be found in spec:

RH-Bugzilla: 1957194
RH-Acked-by: Philippe Mathieu-Daudé <philmd@redhat.com>
Enhance the test to demonstrate existing less-than-stellar behavior of
qemu-img with a qcow2 image containing an inconsistent bitmap: we
don't diagnose the problem until after copying the entire image (a
potentially long time), and when we do diagnose the failure, we still
end up leaving an empty bitmap in the destination. This mess will be
cleaned up in the next patch.
While at it, rename the test now that we support useful iotest names,
and fix a missing newline in the error message thus exposed.

The `aio-max-batch` parameter will be propagated to AIO engines
and it will be used to control the maximum number of queued requests.
When there are in queue a number of requests equal to `aio-max-batch`,
the engine invokes the system call to forward the requests to the kernel.
This parameter allows us to control the maximum batch size to reduce
the latency that requests might accumulate while queued in the AIO
engine queue.
If `aio-max-batch` is equal to 0 (default value), the AIO engine will
use its default maximum batch size value.

Changes in preparation for next patches where we add a new
parameter not related to the poll mechanism.
Let's add two new generic functions (iothread_set_param and
iothread_get_param) that we use to set and get IOThread
parameters.

When there are multiple queues attached to the same AIO context,
some requests may experience high latency, since in the worst case
the AIO engine queue is only flushed when it is full (MAX_EVENTS) or
there are no more queues plugged.
Commit 2558cb8dd4 ("linux-aio: increasing MAX_EVENTS to a larger
hardcoded value") changed MAX_EVENTS from 128 to 1024, to increase
the number of in-flight requests. But this change also increased
the potential maximum batch to 1024 elements.
When there is a single queue attached to the AIO context, the issue
is mitigated from laio_io_unplug() that will flush the queue every
time is invoked since there can't be others queue plugged.
Let's use the new `aio-max-batch` IOThread parameter to mitigate
this issue, limiting the number of requests in a batch.
We also define a default value (32): this value is obtained running
some benchmarks and it represents a good tradeoff between the latency
increase while a request is queued and the cost of the io_submit(2)
system call.

Taking the mutex every time for each dirty bit to clear is too slow, especially
we'll take/release even if the dirty bit is cleared. So far it's only used to
sync with special cases with qemu_guest_free_page_hint() against migration
thread, nothing really that serious yet. Let's move the lock to be upper.
There're two callers of migration_bitmap_clear_dirty().
For migration, move it into ram_save_iterate(). With the help of MAX_WAIT
logic, we'll only run ram_save_iterate() for no more than 50ms-ish time, so
taking the lock once there at the entry. It also means any call sites to
qemu_guest_free_page_hint() can be delayed; but it should be very rare, only
during migration, and I don't see a problem with it.
For COLO, move it up to colo_flush_ram_cache(). I think COLO forgot to take
that lock even when calling ramblock_sync_dirty_bitmap(), where another example
is migration_bitmap_sync() who took it right. So let the mutex cover both the
ramblock_sync_dirty_bitmap() and migration_bitmap_clear_dirty() calls.
It's even possible to drop the lock so we use atomic operations upon rb->bmap
and the variable migration_dirty_pages. I didn't do it just to still be safe,
also not predictable whether the frequent atomic ops could bring overhead too
e.g. on huge vms when it happens very often. When that really comes, we can
keep a local counter and periodically call atomic ops. Keep it simple for now.

Starting from commit b5eea99ec2f5c, qmp_migrate_recover() calls unregister
before calling qemu_start_incoming_migration(). I believe it wanted to mitigate
the next call to yank_register_instance(), but I think that's wrong.
Firstly, if during recover, we should keep the yank instance there, not
"quickly removing and adding it back".
Meanwhile, calling qmp_migrate_recover() twice with b5eea99ec2f5c will directly
crash the dest qemu (right now it can't; but it'll start to work right after
the next patch) because the 1st call of qmp_migrate_recover() will unregister
permanently when the channel failed to establish, then the 2nd call of
qmp_migrate_recover() crashes at yank_unregister_instance().
This patch fixes it by moving yank ops out of qemu_start_incoming_migration()
into qmp_migrate_incoming. For qmp_migrate_recover(), drop the unregister of
yank instance too since we keep it there during the recovery phase.

If the user cancels the migration in the unplug-wait state,
QEMU will try to plug back the card and this fails because the card
is partially unplugged.
To avoid the problem, continue to wait the card unplug, but to
allow the migration to be canceled if the card never finishes to unplug
use a timeout.

The loop is used in migration_thread() and bg_migration_thread(),
so we can move it to its own function and call it from these both places.
Moreover, in migration_thread() we have a wrong state transition from
SETUP to ACTIVE while state could be WAIT_UNPLUG. This is correctly
managed in bg_migration_thread() so use this code instead.

Before switching between AioContexts we need to make sure that we're
fully quiesced ("nb_requests == 0" for every client) when entering the
drained section.
To do this, we set "quiescing = true" for every client on
".drained_begin" to prevent new coroutines from being created, and
check if "nb_requests == 0" on ".drained_poll". Finally, once we're
exiting the drained section, on ".drained_end" we set "quiescing =
false" and call "nbd_client_receive_next_request()" to resume the
processing of new requests.
With these changes, "blk_aio_attach()" and "blk_aio_detach()" can be
reverted to be as simple as they were before f148ae7d36.

RH-Author: Miroslav Rezanina <mrezanin@redhat.com>
RH-Bugzilla: 1957194
osdep.h provides a ROUND_UP macro to hide bitwise operations for the
purpose of rounding a number up to a power of two; add a ROUND_DOWN
macro that does the same with truncation towards zero.
While at it, change the formatting of some comments.

Clang unfortunately does not support generating code for the z900
architecture level and starts with the z10 instead. Thus to be able
to support compiling with Clang, we have to check for the supported
compiler flags. The disadvantage is of course that the bios image
will only run with z10 guest CPUs upwards (which is what most people
use anyway), so just in case let's also emit a warning in that case
(we will continue to ship firmware images that have been pre-built
with GCC in future releases, so this should not impact normal users,
too).

Clang versions before v11.0 insist on having the %rX or %cX register
names instead of just a number. Since our Travis-CI is currently
still using Clang v6.0, we have to fix this to avoid failing jobs.

The cc-option macro is not doing what it should - compared with the
original from the rules.mak file that got removed with commit
660f793093 ("Makefile: inline the relevant parts of rules.mak"),
the arguments got changed and thus the macro is rather doubling
the QEMU_CFLAGS than adding the flag that should be tested.

When building on Fedora 34 (gcc version 11.0.0 20210210) we get:
In file included from pc-bios/s390-ccw/main.c:11:
In function ‘memset’,
inlined from ‘boot_setup’ at pc-bios/s390-ccw/main.c:185:5,

28 | p[i] = c;
| ~~~~~^~~
The offending code is:
memset((char *)S390EP, 0, 6);
where S390EP is a const address:
#define S390EP 0x10008
The compiler doesn't know how big that pointed area is, so it assume that
its length is zero. This has been reported as BZ#99578 to GCC:
"gcc-11 -Warray-bounds or -Wstringop-overread warning when accessing a
pointer from integer literal"
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99578
As this warning does us more harm than good in the BIOS code (where
lot of direct accesses to low memory are done), silence this warning
for all BIOS objects.

When compiling the s390-ccw bios with Clang, the compiler emits a warning:
pc-bios/s390-ccw/main.c:210:5: warning: variable 'found' is used uninitialized
whenever switch default is taken [-Wsometimes-uninitialized]
default:
^~~~~~~
pc-bios/s390-ccw/main.c:214:16: note: uninitialized use occurs here
IPL_assert(found, "Boot device not found\n");
^~~~~
It's a false positive, it only happens because Clang is not smart enough
to see that the panic() function in the "default:" case can never return.
Anyway, let's explicitely mark panic() with "noreturn" to shut up the
warning.

When compiling the s390-ccw bios with clang, it emits a warning like this:
pc-bios/s390-ccw/jump2ipl.c:86:9: warning: indirection of non-volatile null
pointer will be deleted, not trap [-Wnull-dereference]

^~~~~~~~~~~~~~~~
pc-bios/s390-ccw/jump2ipl.c:86:9: note: consider using __builtin_trap() or
qualifying pointer with 'volatile'
We could add a "volatile" here to shut it up, but on the other hand,
we also have a pointer variable called "reset_psw" in this file already
that points to the PSW at address 0, so we can simply use that pointer
variable instead.

When compiling the s390-ccw bios with Clang, the compiler complains:
pc-bios/s390-ccw/bootmap.c:302:9: warning: logical not is only applied
to the left hand side of this comparison [-Wlogical-not-parentheses]
if (!mbr->dev_type == DEV_TYPE_ECKD) {
^ ~~
The code works (more or less by accident), since dev_type can only be
0 or 1, but it's better of course to use the intended != operator here
instead.
Fixes: 5dc739f343 ("Allow booting in case the first virtio-blk disk is bad")

We are using the compiler to do the linking of the bios files. GCC still
accepts the "-Ttext=..." linker flag directly and is smart enough to
pass it to the linker, but in case we are compiling with Clang, we have
to use the official way with the "-Wl," prefix instead.

support:
qemu-system-ppc64: ../softmmu/vl.c:2585: qemu_machine_creation_done: Assertion `machine->cgs->ready' failed.
Aborted
This is happening because we're not setting the cgs->ready flag that is
asserted in qemu_machine_creation_done() during machine start.
cgs->ready is set in s390_pv_kvm_init() and sev_kvm_init(). Let's set it
in kvmppc_svm_init() as well.

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.

RH-Bugzilla: 1957194
RH-Acked-by: Philippe Mathieu-Daudé <philmd@redhat.com>
The point of 'qemu-img convert --bitmaps' is to be a convenience for
actions that are already possible through a string of smaller
'qemu-img bitmap' sub-commands. One situation not accounted for
already is that if a source image contains an inconsistent bitmap (for
example, because a qemu process died abruptly before flushing bitmap
state), the user MUST delete those inconsistent bitmaps before
anything else useful can be done with the image.
We don't want to delete inconsistent bitmaps by default: although a
corrupt bitmap is only a loss of optimization rather than a corruption
of user-visible data, it is still nice to require the user to opt in
to the fact that they are aware of the loss of the bitmap. Still,
requiring the user to check 'qemu-img info' to see whether bitmaps are
consistent, then use 'qemu-img bitmap --remove' to remove offenders,
all before using 'qemu-img convert', is a lot more work than just
adding a knob 'qemu-img convert --bitmaps --skip-broken-bitmaps' which
opts in to skipping the broken bitmaps.
After testing the new option, also demonstrate the way to manually fix
things (either deleting bad bitmaps, or re-creating them as empty) so
that it is possible to convert without the option.

RH-MergeRequest: 35: Synchronize with RHEL-AV 8.5 release 28 to RHEL 9
RH-Commit: [2/4] 3fd8d357c3a365d4bc142b3d339745e5b15c5894 (mrezanin/centos-src-qemu-kvm)
RH-Bugzilla: 1957194
RH-Acked-by: Philippe Mathieu-Daudé <philmd@redhat.com>
Waiting until the end of the convert operation (a potentially
time-consuming task) to finally detect that we can't copy a bitmap is
bad, comparing to failing fast up front. Furthermore, this prevents
us from leaving a file behind with a bitmap that is not marked as
inconsistent even though it does not have sane contents.
This fixes the problems exposed in the previous patch to the iotest:
it adds a fast failure up front, and even if we don't fail early, it
ensures that any bitmap we add but do not properly populate is removed
again rather than left behind incomplete.

RH-Author: Miroslav Rezanina <mrezanin@redhat.com>
RH-MergeRequest: 32: Synchronize with RHEL-AV 8.5 release 27 to RHEL 9
RH-Commit: [6/15] 48586bf5d422cb676a6f2d2cd0abb0822cfc17b2 (mrezanin/centos-src-qemu-kvm)
RH-Bugzilla: 1957194
RH-Acked-by: Stefano Garzarella <sgarzare@redhat.com>

Right now, rate limiting is protected by the AioContext mutex, which is
taken for example both by the block jobs and by qmp_block_job_set_speed
(via find_block_job).
We would like to remove the dependency of block layer code on the
AioContext mutex, since most drivers and the core I/O code are already
not relying on it. However, there is no existing lock that can easily
be taken by both ratelimit_set_speed and ratelimit_calculate_delay,
especially because the latter might run in coroutine context (and
therefore under a CoMutex) but the former will not.
Since concurrent calls to ratelimit_calculate_delay are not possible,
one idea could be to use a seqlock to get a snapshot of slice_ns and
slice_quota. But for now keep it simple, and just add a mutex to the
RateLimit struct; block jobs are generally not performance critical to
the point of optimizing the clock cycles spent in synchronization.
This also requires the introduction of init/destroy functions, so
add them to the two users of ratelimit.h.
