Subject: Initial redhat build
@ -10,10 +10,8 @@ several issues are fixed in QEMU tree:
- 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
- Use "/share/qemu-kvm" as SHARE_SUFFIX
- We reconfigured our share to qemu-kvm to be consistent with used name

This would be difficult to exploit, but that is still related with
CVE-2019-14378 which generates fragmented IP packets that would trigger this
issue and at least produce a DoS.

kvm_set_phys_mem can be called to reallocate a slot by something the
guest does (e.g. writing to PAM and other chipset registers).
This can happen in the middle of a migration, and if we're unlucky
it can now happen between the split 'sync' and 'clear'; the clear
asserts if there's no bmap to clear. Recreate the bmap whenever
we change the slot, keeping the clear path happy.
Typically this is triggered by the guest rebooting during a migrate.

The fix was incomplete as it only protected against requests waiting for
themselves, but not against requests waiting for each other. We need a
different solution.

Migration is silently broken now with x2apic config like this:
-smp 200,maxcpus=288,sockets=2,cores=72,threads=2 \
-device intel-iommu,intremap=on,eim=on
After migration, the guest kernel could hang at anything, due to
x2apic bit not migrated correctly in IA32_APIC_BASE on some vcpus, so
any operations related to x2apic could be broken then (e.g., RDMSR on
x2apic MSRs could fail because KVM would think that the vcpu hasn't
enabled x2apic at all).
The issue is that the x2apic bit was never applied correctly for vcpus
whose ID > 255 when migrate completes, and that's because when we
migrate APIC we use the APICCommonState.id as instance ID of the
migration stream, while that's too short for x2apic.
Let's use the newly introduced initial_apic_id for that.

From: Stefan Reiter <s.reiter@proxmox.com>
All code-paths leading to backup_clean (via job_clean) have the job's
context already acquired. The job's context is guaranteed to be the same
as the one used by backup_top via backup_job_create.
Since the previous logic effectively acquired the lock twice, this
broke cleanup of backups for disks using IO threads, since the BDRV_POLL_WHILE
in bdrv_backup_top_drop -> bdrv_do_drained_begin would only release the lock
once, thus deadlocking with the IO thread.
This is a partial revert of 0abf2581717a19.

When dropping backup-top, we need to drain the node before freeing the
BlockCopyState. Otherwise, requests may still be in flight and then the
assertion in shres_destroy() will fail.
(This becomes visible in intermittent failure of 056.)

bdrv_invalidate_cache_all() assumes that all nodes in a given subtree
are either active or inactive when it starts. Therefore, as soon as it
arrives at an already active node, it stops.
However, this assumption is wrong. For example, it's possible to take a
snapshot of an inactive node, which results in an active overlay over an
inactive backing file. The active overlay is probably also the root node
of an inactive BlockBackend (blk->disable_perm == true).
In this case, bdrv_invalidate_cache_all() does not need to do anything
to activate the overlay node, but it still needs to recurse into the
children and the parents to make sure that after returning success,
really everything is activated.

Waiting in blk_wait_while_drained() while blk->in_flight is increased
for the current request is wrong because it will cause the drain
operation to deadlock.
This patch makes sure that blk_wait_while_drained() is called with
blk->in_flight increased exactly once for the current request, and that
it temporarily decreases the counter while it waits.

external_snapshot_prepare() tries to move the overlay to the AioContext
of the backing file (the snapshotted node). However, it's possible that
this doesn't work, but the backing file can instead be moved to the
overlay's AioContext (e.g. opening the backing chain for a mirror
target).
bdrv_append() already indirectly uses bdrv_attach_node(), which takes
care to move nodes to make sure they use the same AioContext and which
tries both directions.
So the problem has a simple fix: Just delete the unnecessary extra
bdrv_try_set_aio_context() call in external_snapshot_prepare() and
instead assert in bdrv_append() that both nodes were indeed moved to the
same AioContext.

@options is leaked by the first two return statements in this function.
Note that blk_new_open() takes the reference to @options even on
failure, so all we need to do to fix the leak is to move the QDict
allocation down to where we actually need it.

O-Subject: [RHEL-AV-8.2.0 qemu-kvm PATCH 5/6] block: Increase BB.in_flight for coroutine and sync interfaces
Bugzilla: 1817621
RH-Acked-by: Eric Blake <eblake@redhat.com>
RH-Acked-by: Danilo de Paula <ddepaula@redhat.com>
RH-Acked-by: Max Reitz <mreitz@redhat.com>
External callers of blk_co_*() and of the synchronous blk_*() functions
don't currently increase the BlockBackend.in_flight counter, but calls
from blk_aio_*() do, so there is an inconsistency whether the counter
has been increased or not.
This patch moves the actual operations to static functions that can
later know they will always be called with in_flight increased exactly
once, even for external callers using the blk_co_*() coroutine
interfaces.
If the public blk_co_*() interface is unused, remove it.

blockdev-snapshot returned an error if the overlay was already in use,
which it defined as having any BlockBackend parent. This is in fact both
too strict (some parents can tolerate the change of visible data caused
by attaching a backing file) and too loose (some non-BlockBackend
parents may not be happy with it).
One important use case that is prevented by the too strict check is live
storage migration with blockdev-mirror. Here, the target node is
usually opened without a backing file so that the active layer is
mirrored while its backing chain can be copied in the background.
The backing chain should be attached to the mirror target node when
finalising the job, just before switching the users of the source node
to the new copy (at which point the mirror job still has a reference to
the node). drive-mirror did this automatically, but with blockdev-mirror
this is the job of the QMP client, so it needs a way to do this.
blockdev-snapshot is the obvious way, so this patch makes it work in
this scenario. The new condition is that no parent uses CONSISTENT_READ
permissions. This will ensure that the operation will still be blocked
when the node is attached to the guest device, so blockdev-snapshot
remains safe.
(For the sake of completeness, x-blockdev-reopen can be used to achieve
the same, however it is a big hammer, performs the graph change
completely unchecked and is still experimental. So even with the option
of using x-blockdev-reopen, there are reasons why blockdev-snapshot
should be able to perform this operation.)

Move all variants of the flush/pdiscard functions to a single place and
put the blk_co_*() version first because it is called by all other
variants (and will become static in the next patch).

All paths that lead to bdrv_backup_top_drop(), except for the call
from backup_clean(), imply that the BDS AioContext has already been
acquired, so doing it there too can potentially lead to QEMU hanging
on AIO_WAIT_WHILE().
An easy way to trigger this situation is by issuing a two actions
transaction, with a proper and a bogus blockdev-backup, so the second
one will trigger a rollback. This will trigger a hang with an stack
trace like this one:

Fix this by not acquiring the AioContext there, and ensuring all paths
leading to it have it already acquired (backup_clean()).

This patch allows bdrv_reopen() (and therefore the x-blockdev-reopen QMP
command) to attach a node as the new backing file even if the node is in
a different AioContext than the parent if one of both nodes can be moved
to the AioContext of the other node.

From: Max Reitz <mreitz@redhat.com>
When nbd_close() is called from a coroutine, the connection_co never
gets to run, and thus nbd_teardown_connection() hangs.
This is because aio_co_enter() only puts the connection_co into the main
coroutine's wake-up queue, so this main coroutine needs to yield and
wait for connection_co to terminate.

From: Peter Krempa <pkrempa@redhat.com>
The bitmap code requires writing the 'file' child when the qcow2 driver
is reopened in read-write mode.
If the 'file' child is being reopened due to a permissions change, the
modification is commited yet when qcow2_reopen_commit is called. This
means that any attempt to write the 'file' child will end with EBADFD
as the original fd was already closed.
Moving bitmap reopening to the new callback which is called after
permission modifications are commited fixes this as the file descriptor
will be replaced with the correct one.
The above problem manifests itself when reopening 'qcow2' format layer
which uses a 'file-posix' file child which was opened with the
'auto-read-only' property set.

Instead of checking the .bdrv_co_create_opts to see if we need the
fallback, just implement the .bdrv_co_create_opts in the drivers that
need it.
This way we don't break various places that need to know if the
underlying protocol/format really supports image creation, and this way
we still allow some drivers to not support image creation.
Fixes: fd17146cd93d1704cd96d7c2757b325fc7aac6fd
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1816007
Note that technically this driver reverts the image creation fallback
for the vxhs driver since I don't have a means to test it, and IMHO it
is better to leave it not supported as it was prior to generic image
creation patches.
Also drop iscsi_create_opts which was left accidentally.

It is mostly due to missing commit f6dc1c31d3801dcbdf0c56574f9ff4f05180810c

Dirty map addition and removal functions are not acquiring to BDS
AioContext, while they may call to code that expects it to be
acquired.
This may trigger a crash with a stack trace like this one:

Fix this by acquiring the AioContext at qmp_block_dirty_bitmap_add()
and qmp_block_dirty_bitmap_add().

external_snapshot_abort() calls to bdrv_set_backing_hd(), which
returns state->old_bs to the main AioContext, as it's intended to be
used then the BDS is going to be released. As that's not the case when
aborting an external snapshot, return it to the AioContext it was
before the call.
This issue can be triggered by issuing a transaction with two actions,
a proper blockdev-snapshot-sync and a bogus one, so the second will
trigger a transaction abort. This results in a crash with an stack
trace like this one:

Issuing a blockdev-backup from qmp_blockdev_backup takes a slightly
different path than when it's issued from a transaction. In the code,
this is manifested as some redundancy between do_blockdev_backup() and
blockdev_backup_prepare().
This change unifies both paths, merging do_blockdev_backup() and
blockdev_backup_prepare(), and changing qmp_blockdev_backup() to
create a transaction instead of calling do_backup_common() direcly.
As a side-effect, now qmp_blockdev_backup() is executed inside a
drained section, as it happens when creating a blockdev-backup
transaction. This change is visible from the user's perspective, as
the job gets paused and immediately resumed before starting the actual
work.

transaction instead of calling do_backup_common() direcly.
As a side-effect, now qmp_drive_backup() is executed inside a drained
section, as it happens when creating a drive-backup transaction. This
change is visible from the user's perspective, as the job gets paused
and immediately resumed before starting the actual work.
Also fix tests 141, 185 and 219 to cope with the extra
JOB_STATUS_CHANGE lines.

In future patches we'll be performing commands on the slave-fd driven
by commands on queues, since those queues will be driven by individual
threads we need to make sure they don't attempt to use the slave-fd
for multiple commands in parallel.

upstream: Posted and with review-by, not merged yet
Commit 355477f8c73e9 skips rom reset when we're an incoming migration
so as not to overwrite shared ram in the ignore-shared migration
optimisation.
However, it's got an unexpected side effect that because it skips
freeing the ROM data, when rom_reset gets called later on, after
migration (e.g. during a reboot), the ROM does get reset to the original
file contents. Because of seabios/x86's weird reboot process
this confuses a reboot into hanging after a migration.
Fixes: 355477f8c73e9 ("migration: do not rom_reset() during incoming migration")

In order to issue requests on an existing BlockBackend with the
'qemu-io' HMP command, allow specifying the BlockBackend not only with a
BlockBackend name, but also with a qdev ID/QOM path for a device that
owns the (possibly anonymous) BlockBackend.
Because qdev names could be conflicting with BlockBackend and node
names, introduce a -d option to explicitly address a device. If the
option is not given, a BlockBackend or a node is addressed.

Bugzilla: 1782529
RH-Acked-by: Eduardo Habkost <ehabkost@redhat.com>
RH-Acked-by: Igor Mammedov <imammedo@redhat.com>
RH-Acked-by: Laszlo Ersek <lersek@redhat.com>
For Windows driver support, we have to follow this doc in order to
enable Windows to automatically determine the right drivers to install
for a given guest / host combination:
https://docs.microsoft.com/en-us/windows-hardware/drivers/install/specifying-hardware-ids-for-a-computer
Out of the choices available, it was decided that the Windows drivers
will be written to expect use of the scheme documented as "HardwareID-6"
against Windows 10. This uses SMBIOS System (Type 1) and Base Board
(Type 2) tables and will match on
System Manufacturer = Red Hat
System SKU Number = 8.2.0
Baseboard Manufacturer = Red Hat
Baseboard Product = RHEL-AV
The new SMBIOS fields will be tied to machine type and only reported for
pc-q35-8.2.0 machine and later.
The old SMBIOS fields, previously reported by all machines were:
System Manufacturer: Red Hat
System Product Name: KVM
System Version: RHEL-8.2.0 PC (Q35 + ICH9, 2009)
System Family: Red Hat Enterprise Linux
Baseboard Manufacturer: Red Hat
Baseboard Product Name: KVM
Baseboard Version: RHEL-8.2.0 PC (Q35 + ICH9, 2009)
Chassis Manufacturer: Red Hat
Chassis Product Name: KVM
Chassis Version: RHEL-8.2.0 PC (Q35 + ICH9, 2009)
Processor Manufacturer: Red Hat
Processor Product Name: KVM
Processor Version: RHEL-8.2.0 PC (Q35 + ICH9, 2009)
This information will continue to be reported for all machines, except
where it conflicts with the requirement of the new SMBIOS data. IOW,
the "Baseboard Product Name" will change to "RHEL-AV" for pc-q35-8.2.0
machine types and later.
Management applications MUST NEVER override the 4 new SMBIOS fields that
are used for Windows driver matching, with differing values. Aside from
this, they are free to override any other field, including those from
the old SMBIOS field data.
In particular if a management application wants to report its own
product name and version, it is recommended to use "System product"
and "System version" as identifying fields, as these avoid a clash with
the new SMBIOS fields used for Windows drivers.
Note that until now the Baseboard (type 2) table has only been generated
by QEMU if explicitly asked for on the CLI. This patch makes it always
present for new machine types.

Upstream: submitted, Message-Id: <20191205223339.764534-1-ehabkost@redhat.com>
When using `query-cpu-definitions` using `-machine none`,
QEMU is resolving all CPU models to their latest versions. The
actual CPU model version being used by another machine type (e.g.
`pc-q35-4.0`) might be different.
In theory, this was OK because the correct CPU model
version is returned when using the correct `-machine` argument.
Except that in practice, this breaks libvirt expectations:
libvirt always use `-machine none` when checking if a CPU model
is runnable, because runnability is not expected to be affected
when the machine type is changed.
For example, when running on a Haswell host without TSX,
Haswell-v4 is runnable, but Haswell-v1 is not. On those hosts,
`query-cpu-definitions` says Haswell is runnable if using
`-machine none`, but Haswell is actually not runnable using any
of the `pc-*` machine types (because they resolve Haswell to
Haswell-v1). In other words, we're breaking the "runnability
guarantee" we promised to not break for a few releases (see
qemu-deprecated.texi).
To address this issue, change the default CPU model version to v1
on all machine types, so we make `query-cpu-definitions` output
when using `-machine none` match the results when using `pc-*`.
This will change in the future (the plan is to always return the
latest CPU model version if using `-machine none`), but only
after giving libvirt the opportunity to adapt.

This patch adds test cases for attaching the backing chain to a mirror
job target right before finalising the job, where the image is in a
non-mainloop AioContext (i.e. the backing chain needs to be moved to the
AioContext of the mirror target).
This requires switching the test case from virtio-blk to virtio-scsi
because virtio-blk only actually starts using the iothreads when the
guest driver initialises the device (which never happens in a test case
without a guest OS). virtio-scsi always keeps its block nodes in the
AioContext of the the requested iothread without guest interaction.

We have several almost identical copies of a blockdev_create() function
in different test cases. Time to create one unified function in
iotests.py.
To keep the diff managable, this patch only creates the function and
follow-up patches will convert the individual test cases.

We'll want to test more than one successful case in the future, so
prepare the test for that by a refactoring that runs each scenario in a
separate VM.
test_iothreads_switch_{backing,overlay} currently produce errors, but
these are cases that should actually work, by switching either the
backing file node or the overlay node to the AioContext of the other
node.

This tests creating an external snapshot with VM state (which results in
an active overlay over an inactive backing file, which is also the root
node of an inactive BlockBackend), re-activating the images and
performing some operations to test that the re-activation worked as
intended.

The newly tested scenario is a common live storage migration scenario:
The target node is opened without a backing file so that the active
layer is mirrored while its backing chain can be copied in the
background.
The backing chain should be attached to the mirror target node when
finalising the job, just before switching the users of the source node
to the new copy (at which point the mirror job still has a reference to
the node). drive-mirror did this automatically, but with blockdev-mirror
this is the job of the QMP client.
This patch adds test cases for two ways to achieve the desired result,
using either x-blockdev-reopen or blockdev-snapshot.

O-Subject: [RHEL-AV-8.2.0 qemu-kvm PATCH v2 6/6] iotests.py: Let wait_migration wait even more
Bugzilla: 1781637

From: Max Reitz <mreitz@redhat.com>
The "migration completed" event may be sent (on the source, to be
specific) before the migration is actually completed, so the VM runstate
will still be "finish-migrate" instead of "postmigrate". So ask the
users of VM.wait_migration() to specify the final runstate they desire
and then poll the VM until it has reached that state. (This should be
over very quickly, so busy polling is fine.)
Without this patch, I see intermittent failures in the new iotest 280
under high system load. I have not yet seen such failures with other
iotests that use VM.wait_migration() and query-status afterwards, but
maybe they just occur even more rarely, or it is because they also wait
on the destination VM to be running.

From: Felipe Franciosi <felipe@nutanix.com>
When querying an iSCSI server for the provisioning status of blocks (via
GET LBA STATUS), Qemu only validates that the response descriptor zero's
LBA matches the one requested. Given the SCSI spec allows servers to
respond with the status of blocks beyond the end of the LUN, Qemu may
have its heap corrupted by clearing/setting too many bits at the end of
its allocmap for the LUN.
A malicious guest in control of the iSCSI server could carefully program
Qemu's heap (by selectively setting the bitmap) and then smash it.
This limits the number of bits that iscsi_co_block_status() will try to
update in the allocmap so it can't overflow the bitmap.
Fixes: CVE-2020-1711

RH-Acked-by: Eric Blake <eblake@redhat.com>
RH-Acked-by: Danilo de Paula <ddepaula@redhat.com>
RH-Acked-by: Max Reitz <mreitz@redhat.com>
From: Stefan Reiter <s.reiter@proxmox.com>
All callers of job_txn_apply hold a single job's lock, but different
jobs within a transaction can have different contexts, thus we need to
lock each one individually before applying the callback function.
Similar to job_completed_txn_abort this also requires releasing the
caller's context before and reacquiring it after to avoid recursive
locks which might break AIO_WAIT_WHILE in the callback. This is safe, since
existing code would already have to take this into account, lest
job_completed_txn_abort might have broken.
This also brings to light a different issue: When a callback function in
job_txn_apply moves it's job to a different AIO context, callers will
try to release the wrong lock (now that we re-acquire the lock
correctly, previously it would just continue with the old lock, leaving
the job unlocked for the rest of the return path). Fix this by not caching
the job's context.
This is only necessary for qmp_block_job_finalize, qmp_job_finalize and
job_exit, since everyone else calls through job_exit.
One test needed adapting, since it calls job_finalize directly, so it
manually needs to acquire the correct context.

From: "Dr. David Alan Gilbert" <dgilbert@redhat.com>
If a new setmemtable command comes in once the vhost threads are
running, it will remap the guests address space and the threads
will now be looking in the wrong place.
Fortunately we're running this command under lock, so we can
update the queue mappings so that threads will look in the new-right
place.
Note: This doesn't fix things that the threads might be doing
without a lock (e.g. a readv/writev!) That's for another time.

It was always used as 32bit, so define it as used to be clear.
Instead of using -1 as the auto-gen magic value, we switch to
UINT32_MAX. We also make sure that we don't auto-gen this value to
avoid overflowed instance IDs without being noticed.

This function returns true if we are in the middle of a migration.
It is like migration_is_setup_or_active() with CANCELLING and COLO.
Adapt all callers that are needed.

Define the new macro VMSTATE_INSTANCE_ID_ANY for callers who wants to
auto-generate the vmstate instance ID. Previously it was hard coded
as -1 instead of this macro. It helps to change this default value in
the follow up patches. No functional change.

If the migration is cancelled when it is in the completion phase,

The VM maybe wait for the 'pause_sem' semaphore in migration_maybe_pause

When using hugepages, rate limiting is necessary within each huge
page, since a 1G huge page can take a significant time to send, so
you end up with bursty behaviour.

This is a preparation for the next patch:
not use multifd during postcopy.
Without enabling postcopy, everything looks good. While after enabling
postcopy, migration may fail even not use multifd during postcopy. The
reason is the pages is not properly cleared and *old* target page will
continue to be transferred.
After clean pages, migration succeeds.

One multifd will lock all the other multifds' IOChannel mutex to inform them
to quit by setting p->quit or shutting down p->c. In this senario, if some
multifds had already been terminated and multifd_load_cleanup/multifd_save_cleanup
had destroyed their mutex, it could cause destroyed mutex access when trying
lock their mutex.
Here is the coredump stack:

If the multifd_send_threads is not created when migration is failed,
multifd_save_cleanup would be called twice. In this senario, the
multifd_send_state is accessed after it has been released, the result
is that the source VM is crashing down.

One multifd channel will shutdown all the other multifd's IOChannel when it
fails to receive an IOChannel. In this senario, if some multifds had not
received its IOChannel yet, it would try to shutdown its IOChannel which could
cause nullptr access at qio_channel_shutdown.

mirror_wait_for_free_in_flight_slot() just picks a random operation to
wait for. However, when mirror_co_read() waits for free slots, its
MirrorOp is already in s->ops_in_flight, so if not enough slots are
immediately available, an operation can end up waiting for itself to
complete, which results in a hang.
Fix this by passing the current MirrorOp and skipping this operation
when picking an operation to wait for.

If a coroutine is launched, but the coroutine pointer isn't stored
anywhere, debugging any problems inside the coroutine is quite hard.
Let's store the coroutine pointer of a mirror operation in MirrorOp to
have it available in the debugger.

mirror_wait_for_free_in_flight_slot() just picks a random operation to
wait for. However, a MirrorOp is already in s->ops_in_flight when
mirror_co_read() waits for free slots, so if not enough slots are
immediately available, an operation can end up waiting for itself, or
two or more operations can wait for each other to complete, which
results in a hang.
Fix this by adding a flag to MirrorOp that tells us if the request is
already in flight (and therefore occupies slots that it will later
free), and picking only such operations for waiting.

RH-Acked-by: Thomas Huth <thuth@redhat.com>
From: Greg Kurz <groug@kaod.org>
When a CPU is reset, QEMU makes sure no interrupt is pending by clearing
CPUPPCstate::pending_interrupts in ppc_cpu_reset(). In the case of a
complete machine emulation, eg. a sPAPR machine, an external interrupt
request could still be pending in KVM though, eg. an IPI. It will be
eventually presented to the guest, which is supposed to acknowledge it at
the interrupt controller. If the interrupt controller is emulated in QEMU,
either XICS or XIVE, ppc_set_irq() won't deassert the external interrupt
pin in KVM since it isn't pending anymore for QEMU. When the vCPU re-enters
the guest, the interrupt request is still pending and the vCPU will try
again to acknowledge it. This causes an infinite loop and eventually hangs
the guest.
The code has been broken since the beginning. The issue wasn't hit before
because accel=kvm,kernel-irqchip=off is an awkward setup that never got
used until recently with the LC92x IBM systems (aka, Boston).
Add a ppc_irq_reset() function to do the necessary cleanup, ie. deassert
the IRQ pins of the CPU in QEMU and most importantly the external interrupt
pin for this vCPU in KVM.

The power7_set_irq() and power9_set_irq() functions set this but it is
never used actually. Modern Book3s compatible CPUs are only supported
by the pnv and spapr machines. They have an interrupt controller, XICS
for POWER7/8 and XIVE for POWER9, whose models don't require to track
IRQ input states at the CPU level.
Drop these lines to avoid confusion.

For external data file, cluster allocations return an offset in the data
file and are not refcounted. In this case, there is nothing to do for
qcow2_alloc_cluster_abort(). Freeing the same offset in the qcow2 file
is wrong and causes crashes in the better case or image corruption in
the worse case.

job_cancel_sync requires the job's lock to be held, all other callers
already do this (replication_stop, drive_backup_abort,
blockdev_backup_abort, job_cancel_sync_all, cancel_common).
In this case we're in a BlockDriver handler, so we already have a lock,
just assert that it is the same as the one used for the commit_job.

While emulating IRC DCC commands, tcp_emu() uses 'mbuf' size
'm->m_size' to write DCC commands via snprintf(3). This may
lead to OOB write access, because 'bptr' points somewhere in
the middle of 'mbuf' buffer, not at the start. Use M_FREEROOM(m)
size to avoid OOB access.

From: David Gibson <david@gibson.dropbear.id.au>
PAPR allows the interrupt controller used on a POWER9 machine (XICS or
XIVE) to be selected by the guest operating system, by using the
ibm,client-architecture-support (CAS) feature negotiation call.
Currently, if the guest selects an interrupt controller different from the
one selected at initial boot, this causes the system to be reset with the
new model and the boot starts again. This means we run through the SLOF
boot process twice, as well as any other bootloader (e.g. grub) in use
before the OS calls CAS. This can be confusing and/or inconvenient for
users.
Thanks to two fairly recent changes, we no longer need this reboot. 1) we
now completely regenerate the device tree when CAS is called (meaning we
don't need special case updates for all the device tree changes caused by
the interrupt controller mode change), 2) we now have explicit code paths
to activate and deactivate the different interrupt controllers, rather than
just implicitly calling those at machine reset time.
We can therefore eliminate the reboot for changing irq mode, simply by
putting a call to spapr_irq_update_active_intc() before we call
spapr_h_cas_compose_response() (which gives the updated device tree to
the guest firmware and OS).

Bugzilla: 1796240
RH-Acked-by: Danilo de Paula <ddepaula@redhat.com>
RH-Acked-by: Laurent Vivier <lvivier@redhat.com>
RH-Acked-by: Thomas Huth <thuth@redhat.com>
From: David Gibson <david@gibson.dropbear.id.au>
For POWER9 DD2.2 cpus, the best current Spectre v2 indirect branch
mitigation is "count cache disabled", which is configured with:
-machine cap-ibs=fixed-ccd
However, this option isn't available on DD2.3 CPUs with KVM, because they
don't have the count cache disabled.
For POWER9 DD2.3 cpus, it is "count cache flush with assist", configured
with:
-machine cap-ibs=workaround,cap-ccf-assist=on
However this option isn't available on DD2.2 CPUs with KVM, because they
don't have the special CCF assist instruction this relies on.
On current machine types, we default to "count cache flush w/o assist",
that is:
-machine cap-ibs=workaround,cap-ccf-assist=off
This runs, with mitigation on both DD2.2 and DD2.3 host cpus, but has a
fairly significant performance impact.
It turns out we can do better. The special instruction that CCF assist
uses to trigger a count cache flush is a no-op on earlier CPUs, rather than
trapping or causing other badness. It doesn't, of itself, implement the
mitigation, but *if* we have count-cache-disabled, then the count cache
flush is unnecessary, and so using the count cache flush mitigation is
harmless.
Therefore for the new pseries-5.0 machine type, enable cap-ccf-assist by
default. Along with that, suppress throwing an error if cap-ccf-assist
is selected but KVM doesn't support it, as long as KVM *is* giving us
count-cache-disabled. To allow TCG to work out of the box, even though it
doesn't implement the ccf flush assist, downgrade the error in that case to
a warning. This matches several Spectre mitigations where we allow TCG
to operate for debugging, since we don't really make guarantees about TCG
security properties anyway.
While we're there, make the TCG warning for this case match that for other
mitigations.
