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.

RH-Commit: [4/7] 46d4abec352a92112e593ea61b7cbf5ce5f94cdc (peterx/qemu-kvm)
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.

accel/kvm: check for KVM_CAP_READONLY_MEM on VM
KVM_CAP_READONLY_MEM used to be a global capability, but with the
introduction of AMD SEV-SNP confidential VMs, this extension is not
always available on all VM types [1,2].
Query the extension on the VM level instead of on the KVM level.

RH-Commit: [1/1] fef388b1aafce66fa1a176739264bca49596bb94 (seott1/cos-qemu-kvm)
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 differ between RHEL9 and RHEL10
(on a host with pauth support) leading to migration / upgrade failures.
Fix this by disabling pauth for virt-rhel9* machine types in RHEL10.

RH-Commit: [14/22] 0fbba1347acea9983b4fb3d35d1a4c00a09e5579 (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.

RH-Commit: [13/22] 4e5d2d86502ac5ace83f2abe4a48abfba188256d (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.

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.

So far the assumption has always been that if we try to inactivate a
node, it is already idle. This doesn't hold true any more if we allow
inactivating exported nodes because we can't know when new external
requests come in.
Drain the node around setting BDRV_O_INACTIVE so that requests can't
start operating on an active node and then in the middle it suddenly
becomes inactive. With this change, it's enough for exports to check
for new requests that they operate on an active node (or, like reads,
are allowed even on an inactive node).

In order for block_resize to fail gracefully on an inactive node instead
of crashing with an assertion failure in bdrv_co_write_req_prepare()
(called from bdrv_co_truncate()), we need to check for inactive nodes
also when they are attached as a root node and make sure that
BLK_PERM_RESIZE isn't among the permissions allowed for inactive nodes.
To this effect, don't enumerate the permissions that are incompatible
with inactive nodes any more, but allow only BLK_PERM_CONSISTENT_READ
for them.

Putting an active block node on top of an inactive one is strictly
speaking an invalid configuration and the next patch will turn it into a
hard error.
However, taking a snapshot while disk images are inactive after
completing migration has an important use case: After migrating to a
file, taking an external snapshot is what is needed to take a full VM
snapshot.
In order for this to keep working after the later patches, change
creating a snapshot such that it automatically inactivates an overlay
that is added on top of an already inactive node.

RH-Commit: [15/22] fed3cf8ea4bd443ff9bf52328650b43e3ce3150d (kmwolf/centos-qemu-kvm)
Device models have a relatively complex way to set up their block
backends, in which blk_attach_dev() sets blk->disable_perm = true.
We want to support inactive images in exports, too, so that
qemu-storage-daemon can be used with migration. Because they don't use
blk_attach_dev(), they need another way to set this flag. The most
convenient is to do this automatically when an inactive node is attached
to a BlockBackend that can be inactivated.

RH-Commit: [18/22] 0a2723f830936a67fbcc4ee1ee7e846468adc77b (kmwolf/centos-qemu-kvm)
Add an option in BlockExportOptions to allow creating an export on an
inactive node without activating the node. This mode needs to be
explicitly supported by the export type (so that it doesn't perform any
operations that are forbidden for inactive nodes), so this patch alone
doesn't allow this option to be successfully used yet.

+If a ``loadparm`` is specified on both the machine and a device, the per-device

JIRA: https://issues.redhat.com/browse/RHEL-58936
The semantic change has been introduced by commit 5becdc0ab0 ("hostmem:
simplify the code for merge and dump properties") even it clarifies that
no senmatic change has been introduced. After the commit, the merge
property can be applied even the corresponding memory region isn't
initialized yet. This leads to crash dump by the following command
lines.
# /home/gavin/sandbox/qemu.main/build/qemu-system-aarch64 \

:
qemu-system-aarch64: ../system/memory.c:2419: memory_region_get_ram_ptr: \
Assertion `mr->ram_block' failed.
Fix it by applying the merge property only when the memory region is
initialized.

Subject: [PATCH 5/9] hw: Add "loadparm" property to scsi disk devices for
booting on s390x
RH-Author: Thomas Huth <thuth@redhat.com>
RH-MergeRequest: 297: [c10s] Fixes for the new s390x "boot order" feature
RH-Jira: RHEL-68444
RH-Acked-by: Miroslav Rezanina <mrezanin@redhat.com>
RH-Commit: [4/8] 4b5e2afa65f7a529e0bb5509b36c9bf81894caee (thuth/qemu-kvm-cs9)
While adding the new flexible boot order feature on s390x recently,
we missed to add the "loadparm" property to the scsi-hd and scsi-cd
devices. This property is required on s390x to pass the information
to the boot loader about which kernel should be started or whether
the boot menu should be shown. But even more serious: The missing
property is now causing trouble with the corresponding libvirt patches
that assume that the "loadparm" property is either settable for all
bootable devices (when the "boot order" feature is implemented in
QEMU), or none (meaning the behaviour of older QEMUs that only allowed
one "loadparm" at the machine level). To fix this broken situation,
let's implement the "loadparm" property in for the SCSI devices, too.

JIRA: RHEL-67108 <https://issues.redhat.com/browse/RHEL-67108>
Brew build id: 5099404
In commit b88cfee90268cad we defined masks for the IBRD and FBRD
integer and fractional baud rate divider registers, to prevent the
guest from writing invalid values which could cause division-by-zero.
Unfortunately we got the mask values the wrong way around: the FBRD
register is six bits and the IBRD register is 16 bits, not
vice-versa.
You would only run into this bug if you programmed the UART to a baud
rate of less than 9600, because for 9600 baud and above the IBRD
value will fit into 6 bits, as per the table in
https://developer.arm.com/documentation/ddi0183/g/programmers-model/register-descriptions/fractional-baud-rate-register--uartfbrd
The only visible effects would be that the value read back from
the register by the guest would be truncated, and we would
print an incorrect baud rate in the debug logs.

Build an IPLB for any device with a bootindex (up to a maximum of 8 devices).
The IPLB chain is placed immediately before the BIOS in memory. Because this
is not a fixed address, the location of the next IPLB and number of remaining
boot devices is stored in the QIPL global variable for possible later access by
the guest during IPL.

RH-Commit: [5/23] ff245b81b45ddd3a78343d1a8cfdd725a8255d87 (thuth/qemu-kvm-cs9)
Since the netboot code has now been merged into the main s390-ccw.img
binary, we don't need the separate s390-netboot.img anymore. Remove
it and the code that was responsible for loading it.

RH-MergeRequest: 297: [c10s] Fixes for the new s390x "boot order" feature
RH-Jira: RHEL-68444
RH-Acked-by: Miroslav Rezanina <mrezanin@redhat.com>
RH-Commit: [3/8] 7b0fee6a1508649d66b913e6ebf23b4af29628dd (thuth/qemu-kvm-cs9)
Commit bb185de423 ("s390x: Add individual loadparm assignment to
CCW device") added a "loadparm" property to all CCW devices. This
was a little bit unfortunate, since this property is only useful
for devices that can be used for booting, but certainly it is not
useful for devices like virtio-gpu or virtio-tablet.
Thus let's restrict the property to CCW devices that we can boot from
(i.e. virtio-block, virtio-net and vfio-ccw devices).

RH-Commit: [1/23] c33a2769b041e62285eb7840f8a7c05ac32aca7b (thuth/qemu-kvm-cs9)
We are going to link the SLOF libc into the s390-ccw.img, and this
libc needs more memory for providing space for malloc() and friends.
Thus bump the memory size that we reserve for the bios to 3 MiB
instead of only 2 MiB. While we're at it, add a proper check that
there is really enough memory assigned to the machine before blindly
using it.

RH-Commit: [1/1] 7a0f9b816b1ce5f82ae6d0f4686fbb2ca0632e00 (thuth/qemu-kvm-cs9)
balloon_stats_get_all will iterate over guest stats upto the max
VIRTIO_BALLOON_S_NR value, calling visit_type_uint64 to populate
the QObject dict. The dict keys are obtained from the static
array balloon_stat_names which is VIRTIO_BALLOON_S_NR in size.
Unfortunately the way that array is declared results in any
unassigned stats getting a NULL name, which will then cause
visit_type_uint64 to trigger an assert in qobject_output_add_obj.
The balloon_stat_names array was fortunately fully populated with
names until recently:
commit 0d2eeef77a33315187df8519491a900bde4a3d83
Author: Bibo Mao <maobibo@loongson.cn>
Date: Mon Oct 28 10:38:09 2024 +0800
linux-headers: Update to Linux v6.12-rc5
pulled a change to include/standard-headers/linux/virtio_balloon.h
which increased VIRTIO_BALLOON_S_NR by 6, and failed to add the new
names to balloon_stat_names.
This commit fills in the missing names, and uses a static assert to
guarantee that any future changes to VIRTIO_BALLOON_S_NR will cause
a build failure until balloon_stat_names is updated.
This problem was detected by the Cockpit Project's automated
integration tests on QEMU 9.2.0-rc1.

Currently, structures defined in both hw/s390x/ipl.h and pc-bios/s390-ccw/iplb.h
must be kept in sync, which is prone to error. Instead, create a new directory
at include/hw/s390x/ipl/ to contain the definitions that must be shared.

RH-Commit: [22/22] 4715b88d95aefc8b7fdf74f3acb4a45811faea39 (kmwolf/centos-qemu-kvm)
This tests different types of operations on inactive block nodes
(including graph changes, block jobs and NBD exports) to make sure that
users manually activating and inactivating nodes doesn't break things.
Support for inactive nodes in other export types will have to come with
separate test cases because they have different dependencies like blkio
or root permissions and we don't want to disable this basic test when
they are not fulfilled.

RH-Commit: [20/22] 46aecb1c268dcf666c8c7ef8e0d2f3fecaa934e2 (kmwolf/centos-qemu-kvm)
The open-coded form of this filter has been copied into enough tests
that it's better to move it into iotests.py.

RH-Author: Peter Xu <peterx@redhat.com>

error_report() is more appropriate for error situations. Replace fprintf with
error_report() and error_printf() as appropriate. Some improvement in error
reporting also happens as a part of this change. For example:
From:
$ ./qemu-system-x86_64 --accel kvm
Could not access KVM kernel module: No such file or directory
To:
$ ./qemu-system-x86_64 --accel kvm
qemu-system-x86_64: --accel kvm: Could not access KVM kernel module: No such file or directory

RH-Commit: [1/22] a64178a0575a1b921e8a868a8007d0a50eb7ae29 (kmwolf/centos-qemu-kvm)
In 99% cases, after QEMU migrates to dest host, it tries to detect the
target VM runstate using global_state_get_runstate().
There's one outlier so far which is Xen that won't send global state.
That's the major reason why global_state_received() check was always there
together with global_state_get_runstate().
However it's utterly confusing why global_state_received() has anything to
do with "let's start VM or not".
Provide a helper to explain it, then we have an unified entry for getting
the target dest QEMU runstate after migration.

RH-Commit: [1/1] f5c0af772cbd3ced12a7b260f86f98e74d8345d1 (peterx/qemu-kvm)
Libvirt may still use pipes for old file migrations in fd: URI form,
especially when loading old images dumped from Libvirt's compression
algorithms.
In that case, Libvirt needs to compress / uncompress the images on its own
over the migration binary stream, and pipes are passed over to QEMU for
outgoing / incoming migrations in "fd:" URIs.
For future such use case, it should be suggested to use mapped-ram when
saving such VM image. However there can still be old images that was
compressed in such way, so libvirt needs to be able to load those images,
uncompress them and use the same pipe mechanism to pass that over to QEMU.
It means, even if new file migrations can be gradually moved over to
mapped-ram (after Libvirt start supporting it), Libvirt still needs the
uncompressor for the old images to be able to load like before.
Meanwhile since Libvirt currently exposes the compression capability to
guest images, it may needs its own lifecycle management to move that over
to mapped-ram, maybe can be done after mapped-ram saved the image, however
Dan and PeterK raised concern on temporary double disk space consumption.
I suppose for now the easiest is to enable pipes for both sides of "fd:"
migrations, until all things figured out from Libvirt side on how to move
on.
And for "channels" QMP interface support on "migrate" / "migrate-incoming"
commands, we'll also need to move away from pipe. But let's leave that for
later too.
So far, still allow pipes to happen like before on both save/load sides,
just like we would allow sockets to pass.

RH-Commit: [1/1] 4d5a65c294ae83a29db885e42fb3f2ca913c36f0 (hreitz/qemu-kvm-c-9-s)
migration/savevm.c contains some calls to vmstate_save() that are
followed by migrate_set_error() if the integer return value indicates an
error. migrate_set_error() requires that the `Error *` object passed to
it is set. Therefore, vmstate_save() is assumed to always set *errp on
error.
Right now, that assumption is not met: vmstate_save_state_v() (called
internally by vmstate_save()) will not set *errp if
vmstate_subsection_save() or vmsd->post_save() fail. Fix that by adding
an *errp parameter to vmstate_subsection_save(), and by generating a
generic error in case post_save() fails (as is already done for
pre_save()).
Without this patch, qemu will crash after vmstate_subsection_save() or
post_save() have failed inside of a vmstate_save() call (unless
migrate_set_error() then happen to discard the new error because
s->error is already set). This happens e.g. when receiving the state
from a virtio-fs back-end (virtiofsd) fails.

MigrationState

RH-Jira: RHEL-69776

RH-Commit: [1/1] 65c90964461cf884167db18bedf62db7dc242573 (peterx/qemu-kvm)
On the incoming migration side, QEMU uses a coroutine to load all the VM
states. Inside, it may reference MigrationState on global states like
migration capabilities, parameters, error state, shared mutexes and more.
However there's nothing yet to make sure MigrationState won't get
destroyed (e.g. after migration_shutdown()). Meanwhile there's also no API
available to remove the incoming coroutine in migration_shutdown(),
avoiding it to access the freed elements.
There's a bug report showing this can happen and crash dest QEMU when
migration is cancelled on source.
When it happens, the dest main thread is trying to cleanup everything:
#0 qemu_aio_coroutine_enter
#1 aio_dispatch_handler
#2 aio_poll
#3 monitor_cleanup
#4 qemu_cleanup
#5 qemu_default_main
Then it found the migration incoming coroutine, schedule it (even after
migration_shutdown()), causing crash:
#0 __pthread_kill_implementation
#1 __pthread_kill_internal
#2 __GI_raise
#3 __GI_abort
#4 __assert_fail_base
#5 __assert_fail
#6 qemu_mutex_lock_impl
#7 qemu_lockable_mutex_lock
#8 qemu_lockable_lock
#9 qemu_lockable_auto_lock
#10 migrate_set_error
#11 process_incoming_migration_co
#12 coroutine_trampoline
To fix it, take a refcount after an incoming setup is properly done when
qmp_migrate_incoming() succeeded the 1st time. As it's during a QMP
handler which needs BQL, it means the main loop is still alive (without
going into cleanups, which also needs BQL).
Releasing the refcount now only until the incoming migration coroutine
finished or failed. Hence the refcount is valid for both (1) setup phase
of incoming ports, mostly IO watches (e.g. qio_channel_add_watch_full()),
and (2) the incoming coroutine itself (process_incoming_migration_co()).
Note that we can't unref in migration_incoming_state_destroy(), because
both qmp_xen_load_devices_state() and load_snapshot() will use it without
an incoming migration. Those hold BQL so they're not prone to this issue.
PS: I suspect nobody uses Xen's command at all, as it didn't register yank,
hence AFAIU the command should crash on master when trying to unregister
yank in migration_incoming_state_destroy().. but that's another story.
Also note that in some incoming failure cases we may not always unref the
MigrationState refcount, which is a trade-off to keep things simple. We
could make it accurate, but it can be an overkill. Some examples:
- Unlike most of the rest protocols, socket_start_incoming_migration()
may create net listener after incoming port setup sucessfully.
It means we can't unref in migration_channel_process_incoming() as a
generic path because socket protocol might keep using MigrationState.
- For either socket or file, multiple IO watches might be created, it
means logically each IO watch needs to take one refcount for
MigrationState so as to be 100% accurate on ownership of refcount taken.
In general, we at least need per-protocol handling to make it accurate,
which can be an overkill if we know incoming failed after all. Add a short
comment to explain that when taking the refcount in qmp_migrate_incoming().

Postcopy never cared about late-block-active. However there's no mention
in the capability that it doesn't apply to postcopy.
Considering that we _assumed_ late activation is always good, do that too
for postcopy unconditionally, just like precopy. After this patch, we
should have unified the behavior across all.

Src QEMU sets block_inactive=true very early before the invalidation takes
place. It means if something wrong happened during setting the flag but
before reaching qemu_savevm_state_complete_precopy_non_iterable() where it
did the invalidation work, it'll make block_inactive flag inconsistent.
For example, think about when qemu_savevm_state_complete_precopy_iterable()
can fail: it will have block_inactive set to true even if all block drives
are active.
Fix that by only update the flag after the invalidation is done.
No Fixes for any commit, because it's not an issue if bdrv_activate_all()
is re-entrant upon all-active disks - false positive block_inactive can
bring nothing more than "trying to active the blocks but they're already
active". However let's still do it right to avoid the inconsistent flag
v.s. reality.

RH-Commit: [3/22] 9e197765811f282cd133013bd949be9bc49ca249 (kmwolf/centos-qemu-kvm)
Migration capability 'late-block-active' controls when the block drives
will be activated. If enabled, block drives will only be activated until
VM starts, either src runstate was "live" (RUNNING, or SUSPENDED), or it'll
be postponed until qmp_cont().
Let's do this unconditionally. There's no harm to delay activation of
block drives. Meanwhile there's no ABI breakage if dest does it, because
src QEMU has nothing to do with it, so it's no concern on ABI breakage.
IIUC we could avoid introducing this cap when introducing it before, but
now it's still not too late to just always do it. Cap now prone to
removal, but it'll be for later patches.

Subject: [PATCH 06/22] migration/block: Rewrite disk activation
RH-Author: Kevin Wolf <kwolf@redhat.com>

RH-Commit: [6/22] c029cea2613097e1f26c563e6c220a00caa18501 (kmwolf/centos-qemu-kvm)
This patch proposes a flag to maintain disk activation status globally. It
mostly rewrites disk activation mgmt for QEMU, including COLO and QMP
command xen_save_devices_state.
Backgrounds
===========
We have two problems on disk activations, one resolved, one not.
Problem 1: disk activation recover (for switchover interruptions)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
When migration is either cancelled or failed during switchover, especially
when after the disks are inactivated, QEMU needs to remember re-activate
the disks again before vm starts.
It used to be done separately in two paths: one in qmp_migrate_cancel(),
the other one in the failure path of migration_completion().
It used to be fixed in different commits, all over the places in QEMU. So
these are the relevant changes I saw, I'm not sure if it's complete list:
- In 2016, commit fe904ea824 ("migration: regain control of images when
migration fails to complete")
- In 2017, commit 1d2acc3162 ("migration: re-active images while migration
been canceled after inactive them")
- In 2023, commit 6dab4c93ec ("migration: Attempt disk reactivation in
more failure scenarios")
Now since we have a slightly better picture maybe we can unify the
reactivation in a single path.
One side benefit of doing so is, we can move the disk operation outside QMP
command "migrate_cancel". It's possible that in the future we may want to
make "migrate_cancel" be OOB-compatible, while that requires the command
doesn't need BQL in the first place. This will already do that and make
migrate_cancel command lightweight.
Problem 2: disk invalidation on top of invalidated disks
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This is an unresolved bug for current QEMU. Link in "Resolves:" at the
end. It turns out besides the src switchover phase (problem 1 above), QEMU
also needs to remember block activation on destination.
Consider two continuous migration in a row, where the VM was always paused.
In that scenario, the disks are not activated even until migration
completed in the 1st round. When the 2nd round starts, if QEMU doesn't
know the status of the disks, it needs to try inactivate the disk again.
Here the issue is the block layer API bdrv_inactivate_all() will crash a
QEMU if invoked on already inactive disks for the 2nd migration. For
detail, see the bug link at the end.
Implementation
==============
This patch proposes to maintain disk activation with a global flag, so we
know:
- If we used to inactivate disks for migration, but migration got
cancelled, or failed, QEMU will know it should reactivate the disks.
- On incoming side, if the disks are never activated but then another
migration is triggered, QEMU should be able to tell that inactivate is
not needed for the 2nd migration.
We used to have disk_inactive, but it only solves the 1st issue, not the
2nd. Also, it's done in completely separate paths so it's extremely hard
to follow either how the flag changes, or the duration that the flag is
valid, and when we will reactivate the disks.
Convert the existing disk_inactive flag into that global flag (also invert
its naming), and maintain the disk activation status for the whole
lifecycle of qemu. That includes the incoming QEMU.
Put both of the error cases of source migration (failure, cancelled)
together into migration_iteration_finish(), which will be invoked for
either of the scenario. So from that part QEMU should behave the same as
before. However with such global maintenance on disk activation status, we
not only cleanup quite a few temporary paths that we try to maintain the
disk activation status (e.g. in postcopy code), meanwhile it fixes the
crash for problem 2 in one shot.
For freshly started QEMU, the flag is initialized to TRUE showing that the
QEMU owns the disks by default.
For incoming migrated QEMU, the flag will be initialized to FALSE once and
for all showing that the dest QEMU doesn't own the disks until switchover.
That is guaranteed by the "once" variable.

RH-Commit: [10/22] caa43249916319b11a18994510e68176fae61d50 (kmwolf/centos-qemu-kvm)
Block devices have an individual active state, a single global flag
can't cover this correctly. This becomes more important as we allow
users to manually manage which nodes are active or inactive.
Now that it's allowed to call bdrv_inactivate_all() even when some
nodes are already inactive, we can remove the flag and just
unconditionally call bdrv_inactivate_all() and, more importantly,
bdrv_activate_all() before we make use of the nodes.

RH-Author: Eric Blake <eblake@redhat.com>

RH-Commit: [1/1] a66ea3900e0a8515871b6342dfbc0d2c108b4911 (ebblake/centos-qemu-kvm)
While testing the use of qemu-nbd in a Pod of a Kubernetes cluster, I
got LOTS of log messages of the forms:
qemu-nbd: option negotiation failed: Failed to read flags: Unexpected end-of-file before all data were read
qemu-nbd: option negotiation failed: Failed to read flags: Unable to read from socket: Connection reset by peer
While it is nice to warn about clients that aren't following protocol
(in case it helps diagnosing bugs in those clients), a mere port probe
(where the client never write()s any bytes, and where we might even
hit EPIPE in trying to send our greeting to the client) is NOT
abnormal, but merely serves to pollute the log. And Kubernetes
_really_ likes to do port probes to determine whether a given Pod is
up and running.
Easy ways to demonstrate the above port probes:
$ qemu-nbd -r -f raw path/to/file &
$ nc localhost 10809 </dev/null
$ bash -c 'exec </dev/tcp/localhost/10809'
$ kill $!
Silence the noise by not capturing errors until after our first
successful read() from a client.

In order to support running an NBD export on inactive nodes, we must
make sure to return errors for any operations that aren't allowed on
inactive nodes. Reads are the only operation we know we need for
inactive images, so to err on the side of caution, return errors for
everything else, even if some operations could possibly be okay.

b9ad513e1876 ("net: Remove receive_raw()") adds an iovec entry
in qemu_deliver_packet_iov() to add the virtio-net header
in the data when QEMU_NET_PACKET_FLAG_RAW is set but forgets
to increase the number of iovec entries in the array, so
receive_iov() will only send the first entry (the virtio-net
entry, full of 0) and no data. The packet will be discarded.
The only user of QEMU_NET_PACKET_FLAG_RAW is announce_self.
We can see the problem with tcpdump:
- QEMU parameters:

-netdev bridge,id=netdev0,br=virbr0 \
-device virtio-net,mac=9a:2b:2c:2d:2e:2f,netdev=netdev0 \

Because the loadparm specifies an exact kernel the user wants to boot, if the
loadparm is invalid it must represent a misconfiguration of the guest. Thus we
should abort the IPL immediately, without attempting to use other devices, to
avoid booting into an unintended guest image.

RH-Commit: [21/23] 17e89c1a3ca01b9de4683aebdbd06c5350422d27 (thuth/qemu-kvm-cs9)
The assembler directive .align [1] has architecture-dependent behavior,
which may be ambiguous for the reader. Some architectures perform the
alignment in bytes, others in power of two. s390 does in bytes.
Use the directive .balign [2] instead, to clarify that the alignment
request is in bytes. No functional change.

RH-Commit: [22/23] 57de00e48321faf13f673c6d52fd9d59d9be5c83 (thuth/qemu-kvm-cs9)
Commit 7cd50cbe4ca3 ("pc-bios/s390-ccw: Don't use __bss_start with the
"larl" instruction") introduced the address constant bss_start_literal
for __bss_start in the .text section, which introduced a relocation in
code (i.e. TEXTREL). The dedicated constant is required, as __bss_start
may not necessarily be aligned on a 2-byte boundary (see subject commit
for details).
Move the constant to the .data section to get rid of the relocation in
the .text section. Add the linker option -z text to prevent TEXTRELs to
get introduced in the future.
Note that the R_390_RELATIVE relocations are taken care of by function
glue() in include/hw/elf_ops.h.inc introduced by commit 5dce07e1cb67
("elf-loader: Provide the possibility to relocate s390 ELF files").

RH-Commit: [13/23] a78913dc1a9de94de76d484475b967997c457d57 (thuth/qemu-kvm-cs9)
Remove panic-on-error from IPL functions such that a return code is propagated
back to the main IPL calling function (rather than terminating immediately),
which facilitates possible error recovery in the future.
A select few panics remain, which indicate fatal non-devices errors that must
result in termination.

RH-MergeRequest: 331: Fix boot problems when falling back from network to another boot device on s390x [RHEL10]

RH-Commit: [3/4] f7ef8c63507c7f1ee8d05083f9540bee1697071c (thuth/qemu-kvm-cs)
When we are trying to boot from virtio-net devices, the
s390-ccw bios currently leaves the virtio-net device enabled
after using it. That means that the receiving virt queues will
continue to happily write incoming network packets into memory.
This can corrupt data of the following boot process. For example,
if you set up a second guest on a virtual network and create a
lot of broadcast traffic there, e.g. with:
ping -i 0.02 -s 1400 -b 192.168.1.255
and then you try to boot a guest with two boot devices, a network
device first (which should not be bootable) and e.g. a bootable SCSI
CD second, then this guest will fail to load the kernel from the CD
image:
$ qemu-system-s390x -m 2G -nographic -device virtio-scsi-ccw \
-netdev tap,id=net0 -device virtio-net-ccw,netdev=net0,bootindex=1 \
-drive if=none,file=test.iso,format=raw,id=cd1 \
-device scsi-cd,drive=cd1,bootindex=2

We really have to shut up the virtio-net devices after we're not
using it anymore. The easiest way to do this is to simply reset
the device, so let's do that now.

Some packaging tools want to override `LDFLAGS` when building QEMU, this will
result in a build error as most likely no `-nostdlib` flag is passed. Introduce
`EXTRA_LDFLAGS` so that the packager can override `LDFLAGS` without breaking the
build.

RH-Commit: [3/23] 5c7283de7f4e2388e157ea408a44176fdaf5127a (thuth/qemu-kvm-cs9)
We originally built a separate binary for the netboot code since it
was considered as experimental and we could not be sure that the
necessary SLOF module had been checked out. Time passed, the code
proved its usefulness, and the build system nowadays makes sure that
the SLOF module is checked out if you have a s390x compiler available
for building the s390-ccw bios. So there is no real compelling reason
anymore to keep the netboot code in a separate binary. Linking the
code together with the main s390-ccw.img will make future enhancements
much easier, like supporting more than one boot device.

RH-Commit: [6/23] 9ce64794a5c328673cdee6fa058088c3426efad8 (thuth/qemu-kvm-cs9)
Now that the netboot code has been merged into the main s390-ccw.img,
it also does not make sense to keep the build rules in a separate
file. Thus let's merge netboot.mak into the main Makefile.

RH-Commit: [8/8] 8d40508aaf993f2e1b94d471f0e50d0f375e22d2 (thuth/qemu-kvm-cs9)
Now that we can boot from multiple boot devices, we have to make sure
to reinitialize static variables like rx_last_idx to avoid that they
contain garbage data during the second boot attempt (which can lead to
crashes when the code tries to access the wrong ring data).

RH-Commit: [10/23] 3d67ba81c0296f59f5ec2fab3361512e83b6d78d (thuth/qemu-kvm-cs9)
Remove panic-on-error from virtio-scsi IPL specific functions so that error
recovery may be possible in the future.
Functions that would previously panic now provide a return code.

RH-Commit: [4/4] 5b87d859a69ff0f399ba516a87c847a0f3942666 (thuth/qemu-kvm-cs)
The code in net_init_ip() currently bails out early if "rc" is less
than 0, so the if-statements that check for negative "rc" codes to
print out some specific error messages with regards to the TFTP server
are never reached. Move them earlier to bring that dead code back to
life.

Allow attempts to boot from multiple IPL devices. If the first device fails to
IPL, select the pre-built IPLB for the next device in the boot order and attempt
to IPL from it. Continue this process until IPL is successful or there are no
devices left to try.

Commit bb185de423 ("s390x: Add individual loadparm assignment to
CCW device") allowed boot devices to be assigned a loadparm value independent
of the machine value, however, when no boot devices are defined, the machine
loadparm becomes ignored. Therefore, let's check the machine loadparm
prior to probing the devices.

RH-Commit: [1/1] 35242a1fa8fc21f7d73422d23074cd8da5f74781 (anisinha/centos-qemu-kvm)
This is the downstream change equivalent of the upstream QEMU commit
e4e98c7e ("pc: q35: Bump max_cpus to 4096 vcpus")
Since upstream Linux kernel commit
f10a570b093e6 ("KVM: x86: Add CONFIG_KVM_MAX_NR_VCPUS to allow up to 4096 vCPUs")
Linux kernel can support upto a maximum number of 4096 vcpus when MAXSMP is
enabled in the kernel. This upstream change has been backported to c9s kernel
already. Please see JIRA https://issues.redhat.com/browse/RHEL-11579 and the
following commit authored by Vitaly Kuznetsov:
a85f846be686b0a ("KVM: x86: Add CONFIG_KVM_MAX_NR_VCPUS to allow up to 4096 vCPUs")
At present, QEMU has been tested to correctly boot a linux guest with 4096
vcpus using edk2 that has the fixes corresponding to the following two upstream
edk2 PRs:
https://github.com/tianocore/edk2/pull/5410
https://github.com/tianocore/edk2/pull/5418
The changes corresponding to the above two upstream edk2 PRs has been included
in the downstream c9s edk2 with the following MR:
https://gitlab.com/redhat/centos-stream/src/edk2/-/merge_requests/59
So bump up the value max_cpus to 4096 for RHEL q35 machines versions 9.6 and
newer. Q35 RHEL machines versions 9.4 and older continue to support 710 maximum
vcpus as before for compatibility reasons.

RH-Commit: [1/1] fe92e0cd7ab04bfede6d1bf416b1080061cca172 (seott1/cos-qemu-kvm)
PCI hotplug for downstream endpoints on arm fails because Linux'
PCIe hotplug driver doesn't like the QEMU provided LNKSTA:
pcieport 0000:08:01.0: pciehp: Slot(2): Card present
pcieport 0000:08:01.0: pciehp: Slot(2): Link Up
pcieport 0000:08:01.0: pciehp: Slot(2): Cannot train link: status 0x2000
There's 2 cases where LNKSTA isn't setup properly:
* the downstream device has no express capability
* max link width of the bridge is 0
Move the sanity checks added via 88c869198aa63
("pci: Sanity test minimum downstream LNKSTA") outside of the
branch to make sure downstream ports always have a valid LNKSTA.

RH-Commit: [1/4] 4d9ce49f16904d34d4f751f1dec3a53abfe8c8a8 (stefanha/centos-stream-qemu-kvm)
pci_devfn properties accept either a string or an integer as input. To
implement this, set_pci_devfn() first tries to visit the option as a
string, and if that fails, it visits it as an integer instead. While the
QemuOpts visitor happens to accept this, it is invalid according to the
visitor interface. QObject input visitors run into an assertion failure
when this is done.
QObject input visitors are used with the JSON syntax version of -device
on the command line:
$ ./qemu-system-x86_64 -enable-kvm -M q35 -device pcie-pci-bridge,id=pci.1,bus=pcie.0 -blockdev null-co,node-name=disk -device '{ "driver": "virtio-blk-pci", "drive": "disk", "id": "virtio-disk0", "bus": "pci.1", "addr": 1 }'
qemu-system-x86_64: ../qapi/qobject-input-visitor.c:143: QObject *qobject_input_try_get_object(QObjectInputVisitor *, const char *, _Bool): Assertion `removed' failed.
The proper way to accept both strings and integers is using the
alternate mechanism, which tells us the type of the input before it's
visited. With this information, we can directly visit it as the right
type.
This fixes set_pci_devfn() by using the alternate mechanism.

RH-Commit: [3/4] 7c45f3791491cd66ec2476ef0aa515b5bffba456 (stefanha/centos-stream-qemu-kvm)
The QMP device_add monitor command converts the QDict arguments to
QemuOpts and then back again to QDict. This process only supports scalar
types. Device properties like virtio-blk-pci's iothread-vq-mapping (an
array of objects) are silently dropped by qemu_opts_from_qdict() during
the QemuOpts conversion even though QAPI is capable of validating them.
As a result, hotplugging virtio-blk-pci devices with the
iothread-vq-mapping property does not work as expected (the property is
ignored).
Get rid of the QemuOpts conversion in qmp_device_add() and call
qdev_device_add_from_qdict() with from_json=true. Using the QMP
command's QDict arguments directly allows non-scalar properties.
The HMP is also adjusted since qmp_device_add()'s now expects properly
typed JSON arguments and cannot be used from HMP anymore. Move the code
that was previously in qmp_device_add() (with QemuOpts conversion and
from_json=false) into hmp_device_add() so that its behavior is
unchanged.
This patch changes the behavior of QMP device_add but not HMP
device_add. QMP clients that sent incorrectly typed device_add QMP
commands no longer work. This is a breaking change but clients should be
using the correct types already. See the netdev_add QAPIfication in
commit db2a380c8457 for similar reasoning and object-add in commit
9151e59a8b6e. Unlike those commits, we continue to rely on 'gen': false
for the time being.
Markus helped me figure this out and even provided a draft patch. The
code ended up very close to what he suggested.
