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
- Use "/share/qemu-kvm" as SHARE_SUFFIX
- We reconfigured our share to qemu-kvm to be consistent with used name
- 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
- Use "/share/qemu-kvm" as SHARE_SUFFIX
- We reconfigured our share to qemu-kvm to be consistent with used name
This commit is synchronized with qemu-kvm-2.12.0-42.el8 build.

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.

For RHEL, we support 240, for RHV up to 384 VCPUs. Let's limit this
globally instead of fixing up all machines. This way, we can easily
change (increase) the product specific levels later.

The recommended vcpu max limit (KVM_CAP_NR_VCPUS) should be used instead
of the actual max vcpu limit (KVM_CAP_MAX_VCPUS) to give an error.
This commit matches the limit to current KVM_CAP_NR_VCPUS value.

BZ: https://bugzilla.redhat.com/show_bug.cgi?id=1610906
Brew: https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=17624600
Upstream: N/A
Kernel part is in kvm/next, scheduled for 4.19. Patch has been reviewed
upstream but cannot get picked up yet due to the outstanding linux
header sync. Conflict to upstream patch: We have no units.h, therefore
we have to unfold "4*KiB" and "1*MiB".
QEMU has had huge page support for a longer time already, but KVM
memory management under s390x needed some changes to work with huge
backings.
Now that we have support, let's enable it if requested and
available. Otherwise we now properly tell the user if there is no
support and back out instead of failing to run the VM later on.

Upstream: downstream version of 8727315111 ("s390x/cpumodel: default
enable bpb and ppa15 for z196 and later"); downstream does
not have the upstream machine types, instead we need to
turn off the bits for the RHEL 7.5 machine
Most systems and host kernels provide the necessary building blocks for
bpb and ppa15. We can reverse the logic and default enable those
features, while still allowing to disable it via cpu model.
So let us add bpb and ppa15 to z196 and later default CPU model for the
qemu rhel7.6.0 machine. (like -cpu z13). Older machine types (i.e.
s390-ccw-virtio-rhel7.5.0) will retain the old value and not provide those
bits in the default model.

qemu-2.12.0/target/i386/cpu.c:3179: var_assign: Assigning: "props" = storage returned from "qdict_new()".
qemu-2.12.0/target/i386/cpu.c:3217: leaked_storage: Variable "props" going out of scope leaks the storage it points to.
This was introduced by commit b8097deb359b ("i386: Improve
query-cpu-model-expansion full mode").
The leak is only theoretical: if ret->model->props is set to
props, the qapi_free_CpuModelExpansionInfo() call will free props
too in case of errors. The only way for this to not happen is if
we enter the default branch of the switch statement, which would
never happen because all CpuModelExpansionType values are being
handled.
It's still worth to change this to make the allocation logic
easier to follow and make the Coverity error go away. To make
everything simpler, initialize ret->model and ret->model->props
earlier in the function.
While at it, remove redundant check for !prop because prop is
always initialized at the beginning of the function.

O-Subject: [RHEL8/rhel qemu-kvm PATCH 1/1] curl: Make sslverify=off disable host as well as peer verification.
Bugzilla: 1575925
RH-Acked-by: Richard Jones <rjones@redhat.com>
RH-Acked-by: John Snow <jsnow@redhat.com>
RH-Acked-by: Max Reitz <mreitz@redhat.com>
From: "Richard W.M. Jones" <rjones@redhat.com>
The sslverify setting is supposed to turn off all TLS certificate
checks in libcurl. However because of the way we use it, it only
turns off peer certificate authenticity checks
(CURLOPT_SSL_VERIFYPEER). This patch makes it also turn off the check
that the server name in the certificate is the same as the server
you're connecting to (CURLOPT_SSL_VERIFYHOST).
We can use Google's server at 8.8.8.8 which happens to have a bad TLS
certificate to demonstrate this:
$ ./qemu-img create -q -f qcow2 -b 'json: { "file.sslverify": "off", "file.driver": "https", "file.url": "https://8.8.8.8/foo" }' /var/tmp/file.qcow2
qemu-img: /var/tmp/file.qcow2: CURL: Error opening file: SSL: no alternative certificate subject name matches target host name '8.8.8.8'
Could not open backing image to determine size.
With this patch applied, qemu-img connects to the server regardless of
the bad certificate:
$ ./qemu-img create -q -f qcow2 -b 'json: { "file.sslverify": "off", "file.driver": "https", "file.url": "https://8.8.8.8/foo" }' /var/tmp/file.qcow2
qemu-img: /var/tmp/file.qcow2: CURL: Error opening file: The requested URL returned error: 404 Not Found
(The 404 error is expected because 8.8.8.8 is not actually serving a
file called "/foo".)
Of course the default (without sslverify=off) remains to always check
the certificate:
$ ./qemu-img create -q -f qcow2 -b 'json: { "file.driver": "https", "file.url": "https://8.8.8.8/foo" }' /var/tmp/file.qcow2
qemu-img: /var/tmp/file.qcow2: CURL: Error opening file: SSL: no alternative certificate subject name matches target host name '8.8.8.8'
Could not open backing image to determine size.
Further information about the two settings is available here:

Clear have_listen_thread when we exit the thread.
The fallout from this was that various things thought there was
an ongoing postcopy after the postcopy had finished.
The case that failed was postcopy->savevm->loadvm.
This corresponds to RH bug https://bugzilla.redhat.com/show_bug.cgi?id=1608765

There's a couple of error paths in qemu_loadvm_state
which happen early on but after we've initialised the
load state; that needs to be cleaned up otherwise
we can hit asserts if the state gets reinitialised later.

RH-Acked-by: Jeffrey Cody <jcody@redhat.com>

RH-Acked-by: Kevin Wolf <kwolf@redhat.com>
Presently we codify the entry point for a job as the "start" callback,
but a more apt name would be "run" to clarify the idea that when this
function returns we consider the job to have "finished," except for
any cleanup which occurs in separate callbacks later.
As part of this clarification, change the signature to include an error
object and a return code. The error ptr is not yet used, and the return
code while captured, will be overwritten by actions in the job_completed
function.

Jobs presently use both an Error object in the case of the create job,
and char strings in the case of generic errors elsewhere.
Unify the two paths as just j->err, and remove the extra argument from
job_completed. The integer error code for job_completed is kept for now,
to be removed shortly in a separate patch.

All jobs do the same thing when they leave their running loop:
- Store the return code in a structure
- wait to receive this structure in the main thread
- signal job completion via job_completed
Few jobs do anything beyond exactly this. Consolidate this exit
logic for a net reduction in SLOC.
More seriously, when we utilize job_defer_to_main_loop_bh to call
a function that calls job_completed, job_finalize_single will run
in a context where it has recursively taken the aio_context lock,
which can cause hangs if it puts down a reference that causes a flush.
You can observe this in practice by looking at mirror_exit's careful
placement of job_completed and bdrv_unref calls.
If we centralize job exiting, we can signal job completion from outside
of the aio_context, which should allow for job cleanup code to run with
only one lock, which makes cleanup callbacks less tricky to write.

Change the manual deferment to commit_complete into the implicit
callback to job_exit, renaming commit_complete to commit_exit.
This conversion does change the timing of when job_completed is
called to after the bdrv_replace_node and bdrv_unref calls, which
could have implications for bjob->blk which will now be put down
after this cleanup.
Kevin highlights that we did not take any permissions for that backend
at job creation time, so it is safe to reorder these operations.

Change the manual deferment to mirror_exit into the implicit
callback to job_exit and the mirror_exit callback.
This does change the order of some bdrv_unref calls and job_completed,
but thanks to the new context in which we call .exit, this is safe to
defer the possible flushing of any nodes to the job_finalize_single
cleanup stage.

Utilize the job_exit shim by not calling job_defer_to_main_loop, and
where applicable, converting the deferred callback into the job_exit
callback.
This converts backup, stream, create, and the unit tests all at once.
Most of these jobs do not see any changes to the order in which they
clean up their resources, except the test-blockjob-txn test, which
now puts down its bs before job_completed is called.
This is safe for the same reason the reordering in the mirror job is
safe, because job_completed no longer runs under two locks, making
the unref safe even if it causes a flush.

Jobs are now expected to return their retcode on the stack, from the
.run callback, so we can remove that argument.
job_cancel does not need to set -ECANCELED because job_completed will
update the return code itself if the job was canceled.
While we're here, make job_completed static to job.c and remove it from
job.h; move the documentation of return code to the .run() callback and
to the job->ret property, accordingly.

Use the component callbacks; prepare, abort, and clean.
NB: prepare is only called when the job has not yet failed;
and abort can be called after prepare.
complete -> prepare -> abort -> clean
complete -> abort -> clean
During refactor, a potential problem with bdrv_drop_intermediate
was identified, the patched behavior is no worse than the pre-patch
behavior, so leave a FIXME for now to be fixed in a future patch.

Now that all of the jobs use the component finalization callbacks,
there's no use for the heavy-hammer .exit callback anymore.
job_exit becomes a glorified type shim so that we can call
job_completed from aio_bh_schedule_oneshot.
Move these three functions down into job.c to eliminate a
forward reference.

Presently only the backup job really guarantees what one would consider
transactional semantics. To guard against someone helpfully adding them
in the future, document that there are shortcomings in the model that
would need to be audited at that time.

seccomp: use SIGSYS signal instead of killing the thread
The seccomp action SCMP_ACT_KILL results in immediate termination of
the thread that made the bad system call. However, qemu being
multi-threaded, it keeps running. There is no easy way for parent
process / management layer (libvirt) to know about that situation.
Instead, the default SIGSYS handler when invoked with SCMP_ACT_TRAP
will terminate the program and core dump.
This may not be the most secure solution, but probably better than
just killing the offending thread. SCMP_ACT_KILL_PROCESS has been
added in Linux 4.14 to improve the situation, which I propose to use
by default if available in the next patch.

seccomp: prefer SCMP_ACT_KILL_PROCESS if available
The upcoming libseccomp release should have SCMP_ACT_KILL_PROCESS
action (https://github.com/seccomp/libseccomp/issues/96).
SCMP_ACT_KILL_PROCESS is preferable to immediately terminate the
offending process, rather than having the SIGSYS handler running.
Use SECCOMP_GET_ACTION_AVAIL to check availability of kernel support,
as libseccomp will fallback on SCMP_ACT_KILL otherwise, and we still
prefer SCMP_ACT_TRAP.

seccomp: set the seccomp filter to all threads
When using "-seccomp on", the seccomp policy is only applied to the
main thread, the vcpu worker thread and other worker threads created
after seccomp policy is applied; the seccomp policy is not applied to
e.g. the RCU thread because it is created before the seccomp policy is
applied and SECCOMP_FILTER_FLAG_TSYNC isn't used.
This can be verified with
for task in /proc/`pidof qemu`/task/*; do cat $task/status | grep Secc ; done
Seccomp: 2
Seccomp: 0
Seccomp: 0
Seccomp: 2
Seccomp: 2
Seccomp: 2
Starting with libseccomp 2.2.0 and kernel >= 3.17, we can use
seccomp_attr_set(ctx, > SCMP_FLTATR_CTL_TSYNC, 1) to update the policy
on all threads.
libseccomp requirement was bumped to 2.2.0 in previous patch.
libseccomp should fail to set the filter if it can't honour
SCMP_FLTATR_CTL_TSYNC (untested), and thus -sandbox will now fail on
kernel < 3.17.

if MemoryRegion intialization fails it's left in semi-initialized state,
where it's size is not 0 and attached as child to owner object.
And this leds to crash in following use-case:
(monitor) object_add memory-backend-file,id=mem1,size=99999G,mem-path=/tmp/foo,discard-data=yes
memory.c:2083: memory_region_get_ram_ptr: Assertion `mr->ram_block' failed
Aborted (core dumped)
it happens due to assumption that memory region is intialized when
memory_region_size() != 0
and therefore it's ok to access it in
file_backend_unparent()
if (memory_region_size() != 0)
memory_region_get_ram_ptr()
which happens when object_add fails and unparents failed backend making
file_backend_unparent() access invalid memory region.
Fix it by making sure that memory_region_init_foo() APIs cleanup externally
visible side effects on failure (like set size to 0 and unparenting object)

blockdev-mirror with the same node for source and target segfaults
today: A node is in its own backing chain, so mirror_start_job() decides
that this is an active commit. When adding the intermediate nodes with
block_job_add_bdrv(), it starts the iteration through the subchain with
the backing file of source, though, so it never reaches target and
instead runs into NULL at the base.
While we could fix that by starting with source itself, there is no
point in allowing mirroring a node into itself and I wouldn't be
surprised if this caused more problems later.
So just check for this scenario and error out.

The block-commit QMP command required specifying the top and base nodes
of the commit jobs using the file name of that node. While this works
in simple cases (local files with absolute paths), the file names
generated for more complicated setups can be hard to predict.
The block-commit command has more problems than just this, so we want to
replace it altogether in the long run, but libvirt needs a reliable way
to address nodes now. So we don't want to wait for a new, cleaner
command, but just add the minimal thing needed right now.
This adds two new options top-node and base-node to the command, which
allow specifying node names instead. They are mutually exclusive with
the old options.

From: Jeff Cody <jcody@redhat.com>
The function job_cancel_async() will always cause an assert for blockjob
user resume. We set job->user_paused to false, and then call
job->driver->user_resume(). In the case of blockjobs, this is the
block_job_user_resume() function.
In that function, we assert that job.user_paused is set to true.
Unfortunately, right before calling this function, it has explicitly
been set to false.
The fix is pretty simple: set job->user_paused to false only after the
job user_resume() function has been called.

(dbb6da8ba7 "pc: acpi: revert back to 1 SRAT entry for hotpluggable area")
hasn't been backported to RHEL8, it's sufficient to revert commit

The same logic exists in fd polling. This change is especially important
to avoid busy loop once we limit aio_notify_accept() to blocking

BZ: 1623085
An aio_notify() pairs with an aio_notify_accept(). The former should
happen in the main thread or a vCPU thread, and the latter should be
done in the IOThread.
There is one rare case that the main thread or vCPU thread may "steal"
the aio_notify() event just raised by itself, in bdrv_set_aio_context()
[1]. The sequence is like this:
main thread IO Thread
===============================================================
bdrv_drained_begin()
aio_disable_external(ctx)
aio_poll(ctx, true)
ctx->notify_me += 2
...
bdrv_drained_end()
...
aio_notify()
...
bdrv_set_aio_context()
aio_poll(ctx, false)
[1] aio_notify_accept(ctx)
ppoll() /* Hang! */
[1] is problematic. It will clear the ctx->notifier event so that
the blocked ppoll() will not return.
(For the curious, this bug was noticed when booting a number of VMs
simultaneously in RHV. One or two of the VMs will hit this race
condition, making the VIRTIO device unresponsive to I/O commands. When
it hangs, Seabios is busy waiting for a read request to complete (read
MBR), right after initializing the virtio-blk-pci device, using 100%
guest CPU. See also https://bugzilla.redhat.com/show_bug.cgi?id=1562750
for the original bug analysis.)
aio_notify() only injects an event when ctx->notify_me is set,
correspondingly aio_notify_accept() is only useful when ctx->notify_me
_was_ set. Move the call to it into the "blocking" branch. This will
effectively skip [1] and fix the hang.
Furthermore, blocking aio_poll is only allowed on home thread
(in_aio_context_home_thread), because otherwise two blocking
aio_poll()'s can steal each other's ctx->notifier event and cause
hanging just like described above.

BZ: 1632622
It is valid for an aio_set_fd_handler to happen concurrently with
aio_poll. In that case, poll_disable_cnt can change under the heels
of aio_poll, and the assertion on poll_disable_cnt can fail in
run_poll_handlers.
Therefore, this patch simply checks the counter on every polling
iteration. There are no particular needs for ordering, since the
polling loop is terminated anyway by aio_notify at the end of
aio_set_fd_handler.

BZ: 1632622
This is a preparation for the next patch, and also a very small
optimization. Compute the timeout only once, before invoking
try_poll_mode, and adjust it in run_poll_handlers. The adjustment
is the polling time when polling fails, or zero (non-blocking) if
polling succeeds.

BZ: 1632622
Commit 70232b5253 ("aio-posix: Don't count ctx->notifier as progress when
2018-08-15), by not reporting progress, causes aio_poll to execute the
system call when polling succeeds because of ctx->notifier. This introduces
latency before the call to aio_bh_poll() and negates the advantages of
polling, unfortunately.
The fix builds on the previous patch, separating the effect of polling on
the timeout from the progress reported to aio_poll(). ctx->notifier
does zero the timeout, causing the caller to skip the system call,
but it does not report progress, so that the bug fix of commit 70232b5253
still stands.

Bugzilla: 1508142
RH-Acked-by: David Hildenbrand <david@redhat.com>
RH-Acked-by: Cornelia Huck <cohuck@redhat.com>

From: Tony Krowiak <akrowiak@linux.ibm.com>
A new CPU model feature and two new CPU model facilities are
introduced to support AP devices for a KVM guest.
CPU model features:
1. The S390_FEAT_AP CPU model feature indicates whether AP
instructions are available to the guest. This feature will
be enabled only if the AP instructions are available on the
linux host as determined by the availability of the
KVM_S390_VM_CRYPTO_ENABLE_APIE VM attribute which is exposed
by KVM only if the AP instructions are available on the
host.
This feature must be turned on from userspace to execute AP
instructions on the KVM guest. The QEMU command line to turn
this feature on looks something like this:
qemu-system-s390x ... -cpu xxx,ap=on ...
This feature will be supported for zEC12 and newer CPU models.
The feature will not be supported for older models because
there are few older systems on which to test and the older
crypto cards will be going out of service in the relatively
near future.
CPU model facilities:
1. The S390_FEAT_AP_QUERY_CONFIG_INFO feature indicates whether the
AP Query Configuration Information (QCI) facility is available
to the guest as determined by whether the facility is available
on the host. This feature will be exposed by KVM only if the
QCI facility is installed on the host.
2. The S390_FEAT_AP_FACILITY_TEST feature indicates whether the AP
Facility Test (APFT) facility is available to the guest as
determined by whether the facility is available on the host.
This feature will be exposed by KVM only if APFT is installed
on the host.

From: Tony Krowiak <akrowiak@linux.ibm.com>
Let's use the KVM_SET_DEVICE_ATTR ioctl to enable hardware
interpretation of AP instructions executed on the guest.
If the S390_FEAT_AP feature is switched on for the guest,
AP instructions must be interpreted by default; otherwise,
they will be intercepted.
This attribute setting may be overridden by a device. For example,
a device may want to provide AP instructions to the guest (i.e.,
S390_FEAT_AP turned on), but it may want to emulate them. In this
case, the AP instructions executed on the guest must be
intercepted; so when the device is realized, it must disable
interpretation.

From: Tony Krowiak <akrowiak@linux.ibm.com>
Introduces a VFIO based AP device. The device is defined via
the QEMU command line by specifying:
-device vfio-ap,sysfsdev=<path-to-mediated-matrix-device>
There may be only one vfio-ap device configured for a guest.
The mediated matrix device is created by the VFIO AP device
driver by writing a UUID to a sysfs attribute file (see
docs/vfio-ap.txt). The mediated matrix device will be named
after the UUID. Symbolic links to the $uuid are created in
many places, so the path to the mediated matrix device $uuid
can be specified in any of the following ways:
/sys/devices/vfio_ap/matrix/$uuid
/sys/devices/vfio_ap/matrix/mdev_supported_types/vfio_ap-passthrough/devices/$uuid
/sys/bus/mdev/devices/$uuid
/sys/bus/mdev/drivers/vfio_mdev/$uuid
When the vfio-ap device is realized, it acquires and opens the
VFIO iommu group to which the mediated matrix device is
bound. This causes a VFIO group notification event to be
signaled. The vfio_ap device driver's group notification
handler will get called at which time the device driver
will configure the the AP devices to which the guest will
be granted access.

+
+Introduction:
+============
+The IBM Adjunct Processor (AP) Cryptographic Facility is comprised
+of three AP instructions and from 1 to 256 PCIe cryptographic adapter cards.
+These AP devices provide cryptographic functions to all CPUs assigned to a
+linux system running in an IBM Z system LPAR.
+
+On s390x, AP adapter cards are exposed via the AP bus. This document
+describes how those cards may be made available to KVM guests using the
+VFIO mediated device framework.
+
+AP Architectural Overview:
+=========================
+In order understand the terminology used in the rest of this document, let's
+start with some definitions:
+
+* AP adapter
+
+ An AP adapter is an IBM Z adapter card that can perform cryptographic
+ functions. There can be from 0 to 256 adapters assigned to an LPAR depending
+ on the machine model. Adapters assigned to the LPAR in which a linux host is
+ running will be available to the linux host. Each adapter is identified by a
+ number from 0 to 255; however, the maximum adapter number allowed is
+ determined by machine model. When installed, an AP adapter is accessed by
+ AP instructions executed by any CPU.
+
+* AP domain
+
+ An adapter is partitioned into domains. Each domain can be thought of as
+ a set of hardware registers for processing AP instructions. An adapter can
+ hold up to 256 domains; however, the maximum domain number allowed is
+ determined by machine model. Each domain is identified by a number from 0 to
+ 255. Domains can be further classified into two types:
+
+ * Usage domains are domains that can be accessed directly to process AP
+ commands
+
+ * Control domains are domains that are accessed indirectly by AP
+ commands sent to a usage domain to control or change the domain; for
+ example, to set a secure private key for the domain.
+
+* AP Queue
+
+ An AP queue is the means by which an AP command-request message is sent to an
+ AP usage domain inside a specific AP. An AP queue is identified by a tuple
+ comprised of an AP adapter ID (APID) and an AP queue index (APQI). The
+ APQI corresponds to a given usage domain number within the adapter. This tuple
+ forms an AP Queue Number (APQN) uniquely identifying an AP queue. AP
+ instructions include a field containing the APQN to identify the AP queue to
+ which the AP command-request message is to be sent for processing.
+
+* AP Instructions:
+
+ There are three AP instructions:
+
+ * NQAP: to enqueue an AP command-request message to a queue
+ * DQAP: to dequeue an AP command-reply message from a queue
+ * PQAP: to administer the queues
+
+ AP instructions identify the domain that is targeted to process the AP
+ command; this must be one of the usage domains. An AP command may modify a
+ domain that is not one of the usage domains, but the modified domain
+ must be one of the control domains.
+
+Start Interpretive Execution (SIE) Instruction
+==============================================
+A KVM guest is started by executing the Start Interpretive Execution (SIE)
+instruction. The SIE state description is a control block that contains the
+state information for a KVM guest and is supplied as input to the SIE
+instruction. The SIE state description contains a satellite control block called
+the Crypto Control Block (CRYCB). The CRYCB contains three fields to identify
+the adapters, usage domains and control domains assigned to the KVM guest:
+
+* The AP Mask (APM) field is a bit mask that identifies the AP adapters assigned
+ to the KVM guest. Each bit in the mask, from left to right, corresponds to
+ an APID from 0-255. If a bit is set, the corresponding adapter is valid for
+ use by the KVM guest.
+
+* The AP Queue Mask (AQM) field is a bit mask identifying the AP usage domains
+ assigned to the KVM guest. Each bit in the mask, from left to right,
+ corresponds to an AP queue index (APQI) from 0-255. If a bit is set, the
+ corresponding queue is valid for use by the KVM guest.
+
+* The AP Domain Mask field is a bit mask that identifies the AP control domains
+ assigned to the KVM guest. The ADM bit mask controls which domains can be
+ changed by an AP command-request message sent to a usage domain from the
+ guest. Each bit in the mask, from left to right, corresponds to a domain from
+ 0-255. If a bit is set, the corresponding domain can be modified by an AP
+ command-request message sent to a usage domain.
+
+If you recall from the description of an AP Queue, AP instructions include
+an APQN to identify the AP adapter and AP queue to which an AP command-request
+message is to be sent (NQAP and PQAP instructions), or from which a
+command-reply message is to be received (DQAP instruction). The validity of an
+APQN is defined by the matrix calculated from the APM and AQM; it is the
+cross product of all assigned adapter numbers (APM) with all assigned queue
+indexes (AQM). For example, if adapters 1 and 2 and usage domains 5 and 6 are
+assigned to a guest, the APQNs (1,5), (1,6), (2,5) and (2,6) will be valid for
+the guest.
+
+The APQNs can provide secure key functionality - i.e., a private key is stored
+on the adapter card for each of its domains - so each APQN must be assigned to
+at most one guest or the linux host.
+
+ Example 1: Valid configuration:
+ ------------------------------
+ Guest1: adapters 1,2 domains 5,6
+ Guest2: adapter 1,2 domain 7
+
+ This is valid because both guests have a unique set of APQNs: Guest1 has
+ APQNs (1,5), (1,6), (2,5) and (2,6); Guest2 has APQNs (1,7) and (2,7).
+
+ Example 2: Valid configuration:
+ ------------------------------
+ Guest1: adapters 1,2 domains 5,6
+ Guest2: adapters 3,4 domains 5,6
+
+ This is also valid because both guests have a unique set of APQNs:
+ Guest1 has APQNs (1,5), (1,6), (2,5), (2,6);
+ Guest2 has APQNs (3,5), (3,6), (4,5), (4,6)
+
+ Example 3: Invalid configuration:
+ --------------------------------
+ Guest1: adapters 1,2 domains 5,6
+ Guest2: adapter 1 domains 6,7
+
+ This is an invalid configuration because both guests have access to
+ APQN (1,6).
+
+AP Matrix Configuration on Linux Host:
+=====================================
+A linux system is a guest of the LPAR in which it is running and has access to
+the AP resources configured for the LPAR. The LPAR's AP matrix is
+configured via its Activation Profile which can be edited on the HMC. When the
+linux system is started, the AP bus will detect the AP devices assigned to the
+LPAR and create the following in sysfs:
+
+/sys/bus/ap
+... [devices]
+...... xx.yyyy
+...... ...
+...... cardxx
+...... ...
+
+Where:
+ cardxx is AP adapter number xx (in hex)
+....xx.yyyy is an APQN with xx specifying the APID and yyyy specifying the
+ APQI
+
+For example, if AP adapters 5 and 6 and domains 4, 71 (0x47), 171 (0xab) and
+255 (0xff) are configured for the LPAR, the sysfs representation on the linux
+host system would look like this:
+
+/sys/bus/ap
+... [devices]
+...... 05.0004
+...... 05.0047
+...... 05.00ab
+...... 05.00ff
+...... 06.0004
+...... 06.0047
+...... 06.00ab
+...... 06.00ff
+...... card05
+...... card06
+
+A set of default device drivers are also created to control each type of AP
+device that can be assigned to the LPAR on which a linux host is running:
+
+/sys/bus/ap
+... [drivers]
+...... [cex2acard] for Crypto Express 2/3 accelerator cards
+...... [cex2aqueue] for AP queues served by Crypto Express 2/3
+ accelerator cards
+...... [cex4card] for Crypto Express 4/5/6 accelerator and coprocessor
+ cards
+...... [cex4queue] for AP queues served by Crypto Express 4/5/6
+ accelerator and coprocessor cards
+...... [pcixcccard] for Crypto Express 2/3 coprocessor cards
+...... [pcixccqueue] for AP queues served by Crypto Express 2/3
+ coprocessor cards
+
+Binding AP devices to device drivers
+------------------------------------
+There are two sysfs files that specify bitmasks marking a subset of the APQN
+range as 'usable by the default AP queue device drivers' or 'not usable by the
+default device drivers' and thus available for use by the alternate device
+driver(s). The sysfs locations of the masks are:
+
+ /sys/bus/ap/apmask
+ /sys/bus/ap/aqmask
+
+ The 'apmask' is a 256-bit mask that identifies a set of AP adapter IDs
+ (APID). Each bit in the mask, from left to right (i.e., from most significant
+ to least significant bit in big endian order), corresponds to an APID from
+ 0-255. If a bit is set, the APID is marked as usable only by the default AP
+ queue device drivers; otherwise, the APID is usable by the vfio_ap
+ device driver.
+
+ The 'aqmask' is a 256-bit mask that identifies a set of AP queue indexes
+ (APQI). Each bit in the mask, from left to right (i.e., from most significant
+ to least significant bit in big endian order), corresponds to an APQI from
+ 0-255. If a bit is set, the APQI is marked as usable only by the default AP
+ queue device drivers; otherwise, the APQI is usable by the vfio_ap device
+ driver.
+
+ Take, for example, the following mask:
+
+ 0x7dffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff
+
+ It indicates:
+
+ 1, 2, 3, 4, 5, and 7-255 belong to the default drivers' pool, and 0 and 6
+ belong to the vfio_ap device driver's pool.
+
+ The APQN of each AP queue device assigned to the linux host is checked by the
+ AP bus against the set of APQNs derived from the cross product of APIDs
+ and APQIs marked as usable only by the default AP queue device drivers. If a
+ match is detected, only the default AP queue device drivers will be probed;
+ otherwise, the vfio_ap device driver will be probed.
+
+ By default, the two masks are set to reserve all APQNs for use by the default
+ AP queue device drivers. There are two ways the default masks can be changed:
+
+ 1. The sysfs mask files can be edited by echoing a string into the
+ respective sysfs mask file in one of two formats:
+
+ * An absolute hex string starting with 0x - like "0x12345678" - sets
+ the mask. If the given string is shorter than the mask, it is padded
+ with 0s on the right; for example, specifying a mask value of 0x41 is
+ the same as specifying:
+
+ 0x4100000000000000000000000000000000000000000000000000000000000000
+
+ Keep in mind that the mask reads from left to right (i.e., most
+ significant to least significant bit in big endian order), so the mask
+ above identifies device numbers 1 and 7 (01000001).
+
+ If the string is longer than the mask, the operation is terminated with
+ an error (EINVAL).
+
+ * Individual bits in the mask can be switched on and off by specifying
+ each bit number to be switched in a comma separated list. Each bit
+ number string must be prepended with a ('+') or minus ('-') to indicate
+ the corresponding bit is to be switched on ('+') or off ('-'). Some
+ valid values are:
+
+ "+0" switches bit 0 on
+ "-13" switches bit 13 off
+ "+0x41" switches bit 65 on
+ "-0xff" switches bit 255 off
+
+ The following example:
+ +0,-6,+0x47,-0xf0
+
+ Switches bits 0 and 71 (0x47) on
+ Switches bits 6 and 240 (0xf0) off
+
+ Note that the bits not specified in the list remain as they were before
+ the operation.
+
+ 2. The masks can also be changed at boot time via parameters on the kernel
+ command line like this:
+
+ ap.apmask=0xffff ap.aqmask=0x40
+
+ This would create the following masks:
+
+ apmask:
+ 0xffff000000000000000000000000000000000000000000000000000000000000
+
+ aqmask:
+ 0x4000000000000000000000000000000000000000000000000000000000000000
+
+ Resulting in these two pools:
+
+ default drivers pool: adapter 0-15, domain 1
+ alternate drivers pool: adapter 16-255, domains 0, 2-255
+
+Configuring an AP matrix for a linux guest.
+------------------------------------------
+The sysfs interfaces for configuring an AP matrix for a guest are built on the
+VFIO mediated device framework. To configure an AP matrix for a guest, a
+mediated matrix device must first be created for the /sys/devices/vfio_ap/matrix
+device. When the vfio_ap device driver is loaded, it registers with the VFIO
+mediated device framework. When the driver registers, the sysfs interfaces for
+creating mediated matrix devices is created:
+
+/sys/devices
+... [vfio_ap]
+......[matrix]
+......... [mdev_supported_types]
+............ [vfio_ap-passthrough]
+............... create
+............... [devices]
+
+A mediated AP matrix device is created by writing a UUID to the attribute file
+named 'create', for example:
+
+ uuidgen > create
+
+ or
+
+ echo $uuid > create
+
+When a mediated AP matrix device is created, a sysfs directory named after
+the UUID is created in the 'devices' subdirectory:
+
+/sys/devices
+... [vfio_ap]
+......[matrix]
+......... [mdev_supported_types]
+............ [vfio_ap-passthrough]
+............... create
+............... [devices]
+.................. [$uuid]
+
+There will also be three sets of attribute files created in the mediated
+matrix device's sysfs directory to configure an AP matrix for the
+KVM guest:
+
+/sys/devices
+... [vfio_ap]
+......[matrix]
+......... [mdev_supported_types]
+............ [vfio_ap-passthrough]
+............... create
+............... [devices]
+.................. [$uuid]
+..................... assign_adapter
+..................... assign_control_domain
+..................... assign_domain
+..................... matrix
+..................... unassign_adapter
+..................... unassign_control_domain
+..................... unassign_domain
+
+assign_adapter
+ To assign an AP adapter to the mediated matrix device, its APID is written
+ to the 'assign_adapter' file. This may be done multiple times to assign more
+ than one adapter. The APID may be specified using conventional semantics
+ as a decimal, hexadecimal, or octal number. For example, to assign adapters
+ 4, 5 and 16 to a mediated matrix device in decimal, hexadecimal and octal
+ respectively:
+
+ echo 4 > assign_adapter
+ echo 0x5 > assign_adapter
+ echo 020 > assign_adapter
+
+ In order to successfully assign an adapter:
+
+ * The adapter number specified must represent a value from 0 up to the
+ maximum adapter number allowed by the machine model. If an adapter number
+ higher than the maximum is specified, the operation will terminate with
+ an error (ENODEV).
+
+ * All APQNs that can be derived from the adapter ID being assigned and the
+ IDs of the previously assigned domains must be bound to the vfio_ap device
+ driver. If no domains have yet been assigned, then there must be at least
+ one APQN with the specified APID bound to the vfio_ap driver. If no such
+ APQNs are bound to the driver, the operation will terminate with an
+ error (EADDRNOTAVAIL).
+
+ No APQN that can be derived from the adapter ID and the IDs of the
+ previously assigned domains can be assigned to another mediated matrix
+ device. If an APQN is assigned to another mediated matrix device, the
+ operation will terminate with an error (EADDRINUSE).
+
+unassign_adapter
+ To unassign an AP adapter, its APID is written to the 'unassign_adapter'
+ file. This may also be done multiple times to unassign more than one adapter.
+
+assign_domain
+ To assign a usage domain, the domain number is written into the
+ 'assign_domain' file. This may be done multiple times to assign more than one
+ usage domain. The domain number is specified using conventional semantics as
+ a decimal, hexadecimal, or octal number. For example, to assign usage domains
+ 4, 8, and 71 to a mediated matrix device in decimal, hexadecimal and octal
+ respectively:
+
+ echo 4 > assign_domain
+ echo 0x8 > assign_domain
+ echo 0107 > assign_domain
+
+ In order to successfully assign a domain:
+
+ * The domain number specified must represent a value from 0 up to the
+ maximum domain number allowed by the machine model. If a domain number
+ higher than the maximum is specified, the operation will terminate with
+ an error (ENODEV).
+
+ * All APQNs that can be derived from the domain ID being assigned and the IDs
+ of the previously assigned adapters must be bound to the vfio_ap device
+ driver. If no domains have yet been assigned, then there must be at least
+ one APQN with the specified APQI bound to the vfio_ap driver. If no such
+ APQNs are bound to the driver, the operation will terminate with an
+ error (EADDRNOTAVAIL).
+
+ No APQN that can be derived from the domain ID being assigned and the IDs
+ of the previously assigned adapters can be assigned to another mediated
+ matrix device. If an APQN is assigned to another mediated matrix device,
+ the operation will terminate with an error (EADDRINUSE).
+
+unassign_domain
+ To unassign a usage domain, the domain number is written into the
+ 'unassign_domain' file. This may be done multiple times to unassign more than
+ one usage domain.
+
+assign_control_domain
+ To assign a control domain, the domain number is written into the
+ 'assign_control_domain' file. This may be done multiple times to
+ assign more than one control domain. The domain number may be specified using
+ conventional semantics as a decimal, hexadecimal, or octal number. For
+ example, to assign control domains 4, 8, and 71 to a mediated matrix device
+ in decimal, hexadecimal and octal respectively:
+
+ echo 4 > assign_domain
+ echo 0x8 > assign_domain
+ echo 0107 > assign_domain
+
+ In order to successfully assign a control domain, the domain number
+ specified must represent a value from 0 up to the maximum domain number
+ allowed by the machine model. If a control domain number higher than the
+ maximum is specified, the operation will terminate with an error (ENODEV).
+
+unassign_control_domain
+ To unassign a control domain, the domain number is written into the
+ 'unassign_domain' file. This may be done multiple times to unassign more than
+ one control domain.
+
+Notes: Hot plug/unplug is not currently supported for mediated AP matrix
+devices, so no changes to the AP matrix will be allowed while a guest using
+the mediated matrix device is running. Attempts to assign an adapter,
+domain or control domain will be rejected and an error (EBUSY) returned.
+
+Starting a Linux Guest Configured with an AP Matrix:
+===================================================
+To provide a mediated matrix device for use by a guest, the following option
+must be specified on the QEMU command line:
+
+ -device vfio_ap,sysfsdev=$path-to-mdev
+
+The sysfsdev parameter specifies the path to the mediated matrix device.
+There are a number of ways to specify this path:
+
+/sys/devices/vfio_ap/matrix/$uuid
+/sys/bus/mdev/devices/$uuid
+/sys/bus/mdev/drivers/vfio_mdev/$uuid
+/sys/devices/vfio_ap/matrix/mdev_supported_types/vfio_ap-passthrough/devices/$uuid
+
+When the linux guest is started, the guest will open the mediated
+matrix device's file descriptor to get information about the mediated matrix
+device. The vfio_ap device driver will update the APM, AQM, and ADM fields in
+the guest's CRYCB with the adapter, usage domain and control domains assigned
+via the mediated matrix device's sysfs attribute files. Programs running on the
+linux guest will then:
+
+1. Have direct access to the APQNs derived from the cross product of the AP
+ adapter numbers (APID) and queue indexes (APQI) specified in the APM and AQM
+ fields of the guests's CRYCB respectively. These APQNs identify the AP queues
+ that are valid for use by the guest; meaning, AP commands can be sent by the
+ guest to any of these queues for processing.
+
+2. Have authorization to process AP commands to change a control domain
+ identified in the ADM field of the guest's CRYCB. The AP command must be sent
+ to a valid APQN (see 1 above).
+
+CPU model features:
+
+Three CPU model features are available for controlling guest access to AP
+facilities:
+
+1. AP facilities feature
+
+ The AP facilities feature indicates that AP facilities are installed on the
+ guest. This feature will be exposed for use only if the AP facilities
+ are installed on the host system. The feature is s390-specific and is
+ represented as a parameter of the -cpu option on the QEMU command line:
+
+ qemu-system-s390x -cpu $model,ap=on|off
+
+ Where:
+
+ $model is the CPU model defined for the guest (defaults to the model of
+ the host system if not specified).
+
+ ap=on|off indicates whether AP facilities are installed (on) or not
+ (off). The default for CPU models zEC12 or newer
+ is ap=on. AP facilities must be installed on the guest if a
+ vfio-ap device (-device vfio-ap,sysfsdev=$path) is configured
+ for the guest, or the guest will fail to start.
+
+2. Query Configuration Information (QCI) facility
+
+ The QCI facility is used by the AP bus running on the guest to query the
+ configuration of the AP facilities. This facility will be available
+ only if the QCI facility is installed on the host system. The feature is
+ s390-specific and is represented as a parameter of the -cpu option on the
+ QEMU command line:
+
+ qemu-system-s390x -cpu $model,apqci=on|off
+
+ Where:
+
+ $model is the CPU model defined for the guest
+
+ apqci=on|off indicates whether the QCI facility is installed (on) or
+ not (off). The default for CPU models zEC12 or newer
+ is apqci=on; for older models, QCI will not be installed.
+
+ If QCI is installed (apqci=on) but AP facilities are not
+ (ap=off), an error message will be logged, but the guest
+ will be allowed to start. It makes no sense to have QCI
+ installed if the AP facilities are not; this is considered
+ an invalid configuration.
+
+ If the QCI facility is not installed, APQNs with an APQI
+ greater than 15 will not be detected by the AP bus
+ running on the guest.
+
+3. Adjunct Process Facility Test (APFT) facility
+
+ The APFT facility is used by the AP bus running on the guest to test the
+ AP facilities available for a given AP queue. This facility will be available
+ only if the APFT facility is installed on the host system. The feature is
+ s390-specific and is represented as a parameter of the -cpu option on the
+ QEMU command line:
+
+ qemu-system-s390x -cpu $model,apft=on|off
+
+ Where:
+
+ $model is the CPU model defined for the guest (defaults to the model of
+ the host system if not specified).
+
+ apft=on|off indicates whether the APFT facility is installed (on) or
+ not (off). The default for CPU models zEC12 and
+ newer is apft=on for older models, APFT will not be
+ installed.
+
+ If APFT is installed (apft=on) but AP facilities are not
+ (ap=off), an error message will be logged, but the guest
+ will be allowed to start. It makes no sense to have APFT
+ installed if the AP facilities are not; this is considered
+ an invalid configuration.
+
+ It also makes no sense to turn APFT off because the AP bus
+ running on the guest will not detect CEX4 and newer devices
+ without it. Since only CEX4 and newer devices are supported
+ for guest usage, no AP devices can be made accessible to a
+ guest started without APFT installed.
+
+Example: Configure AP Matrixes for Three Linux Guests:
+=====================================================
+Let's now provide an example to illustrate how KVM guests may be given
+access to AP facilities. For this example, we will show how to configure
+three guests such that executing the lszcrypt command on the guests would
+look like this:
+
+Guest1
+------
+CARD.DOMAIN TYPE MODE
+------------------------------
+05 CEX5C CCA-Coproc
+05.0004 CEX5C CCA-Coproc
+05.00ab CEX5C CCA-Coproc
+06 CEX5A Accelerator
+06.0004 CEX5A Accelerator
+06.00ab CEX5C CCA-Coproc
+
+Guest2
+------
+CARD.DOMAIN TYPE MODE
+------------------------------
+05 CEX5A Accelerator
+05.0047 CEX5A Accelerator
+05.00ff CEX5A Accelerator (5,4), (5,171), (6,4), (6,171),
+
+Guest3
+------
+CARD.DOMAIN TYPE MODE
+------------------------------
+06 CEX5A Accelerator
+06.0047 CEX5A Accelerator
+06.00ff CEX5A Accelerator
+
+These are the steps:
+
+1. Install the vfio_ap module on the linux host. The dependency chain for the
+ vfio_ap module is:
+ * iommu
+ * s390
+ * zcrypt
+ * vfio
+ * vfio_mdev
+ * vfio_mdev_device
+ * KVM
+
+ To build the vfio_ap module, the kernel build must be configured with the
+ following Kconfig elements selected:
+ * IOMMU_SUPPORT
+ * S390
+ * ZCRYPT
+ * S390_AP_IOMMU
+ * VFIO
+ * VFIO_MDEV
+ * VFIO_MDEV_DEVICE
+ * KVM
+
+ If using make menuconfig select the following to build the vfio_ap module:
+ -> Device Drivers
+ -> IOMMU Hardware Support
+ select S390 AP IOMMU Support
+ -> VFIO Non-Privileged userspace driver framework
+ -> Mediated device driver frramework
+ -> VFIO driver for Mediated devices
+ -> I/O subsystem
+ -> VFIO support for AP devices
+
+2. Secure the AP queues to be used by the three guests so that the host can not
+ access them. To secure the AP queues 05.0004, 05.0047, 05.00ab, 05.00ff,
+ 06.0004, 06.0047, 06.00ab, and 06.00ff for use by the vfio_ap device driver,
+ the corresponding APQNs must be removed from the default queue drivers pool
+ as follows:
+
+ echo -5,-6 > /sys/bus/ap/apmask
+
+ echo -4,-0x47,-0xab,-0xff > /sys/bus/ap/aqmask
+
+ This will result in AP queues 05.0004, 05.0047, 05.00ab, 05.00ff, 06.0004,
+ 06.0047, 06.00ab, and 06.00ff getting bound to the vfio_ap device driver. The
+ sysfs directory for the vfio_ap device driver will now contain symbolic links
+ to the AP queue devices bound to it:
+
+ /sys/bus/ap
+ ... [drivers]
+ ...... [vfio_ap]
+ ......... [05.0004]
+ ......... [05.0047]
+ ......... [05.00ab]
+ ......... [05.00ff]
+ ......... [06.0004]
+ ......... [06.0047]
+ ......... [06.00ab]
+ ......... [06.00ff]
+
+ Keep in mind that only type 10 and newer adapters (i.e., CEX4 and later)
+ can be bound to the vfio_ap device driver. The reason for this is to
+ simplify the implementation by not needlessly complicating the design by
+ supporting older devices that will go out of service in the relatively near
+ future, and for which there are few older systems on which to test.
+
+ The administrator, therefore, must take care to secure only AP queues that
+ can be bound to the vfio_ap device driver. The device type for a given AP
+ queue device can be read from the parent card's sysfs directory. For example,
+ to see the hardware type of the queue 05.0004:
+
+ cat /sys/bus/ap/devices/card05/hwtype
+
+ The hwtype must be 10 or higher (CEX4 or newer) in order to be bound to the
+ vfio_ap device driver.
+
+3. Create the mediated devices needed to configure the AP matrixes for the
+ three guests and to provide an interface to the vfio_ap driver for
+ use by the guests:
+
+ /sys/devices/vfio_ap/matrix/
+ --- [mdev_supported_types]
+ ------ [vfio_ap-passthrough] (passthrough mediated matrix device type)
+ --------- create
+ --------- [devices]
+
+ To create the mediated devices for the three guests:
+
+ uuidgen > create
+ uuidgen > create
+ uuidgen > create
+
+ or
+
+ echo $uuid1 > create
+ echo $uuid2 > create
+ echo $uuid3 > create
+
+ This will create three mediated devices in the [devices] subdirectory named
+ after the UUID used to create the mediated device. We'll call them $uuid1,
+ $uuid2 and $uuid3 and this is the sysfs directory structure after creation:
+
+ /sys/devices/vfio_ap/matrix/
+ --- [mdev_supported_types]
+ ------ [vfio_ap-passthrough]
+ --------- [devices]
+ ------------ [$uuid1]
+ --------------- assign_adapter
+ --------------- assign_control_domain
+ --------------- assign_domain
+ --------------- matrix
+ --------------- unassign_adapter
+ --------------- unassign_control_domain
+ --------------- unassign_domain
+
+ ------------ [$uuid2]
+ --------------- assign_adapter
+ --------------- assign_control_domain
+ --------------- assign_domain
+ --------------- matrix
+ --------------- unassign_adapter
+ ----------------unassign_control_domain
+ ----------------unassign_domain
+
+ ------------ [$uuid3]
+ --------------- assign_adapter
+ --------------- assign_control_domain
+ --------------- assign_domain
+ --------------- matrix
+ --------------- unassign_adapter
+ ----------------unassign_control_domain
+ ----------------unassign_domain
+
+4. The administrator now needs to configure the matrixes for the mediated
+ devices $uuid1 (for Guest1), $uuid2 (for Guest2) and $uuid3 (for Guest3).
+
+ This is how the matrix is configured for Guest1:
+
+ echo 5 > assign_adapter
+ echo 6 > assign_adapter
+ echo 4 > assign_domain
+ echo 0xab > assign_domain
+
+ Control domains can similarly be assigned using the assign_control_domain
+ sysfs file.
+
+ If a mistake is made configuring an adapter, domain or control domain,
+ you can use the unassign_xxx interfaces to unassign the adapter, domain or
+ control domain.
+
+ To display the matrix configuration for Guest1:
+
+ cat matrix
+
+ The output will display the APQNs in the format xx.yyyy, where xx is
+ the adapter number and yyyy is the domain number. The output for Guest1
+ will look like this:
+
+ 05.0004
+ 05.00ab
+ 06.0004
+ 06.00ab
+
+ This is how the matrix is configured for Guest2:
+
+ echo 5 > assign_adapter
+ echo 0x47 > assign_domain
+ echo 0xff > assign_domain
+
+ This is how the matrix is configured for Guest3:
+
+ echo 6 > assign_adapter
+ echo 0x47 > assign_domain
+ echo 0xff > assign_domain
+
+5. Start Guest1:
+
+ /usr/bin/qemu-system-s390x ... -cpu host,ap=on,apqci=on,apft=on \
+ -device vfio-ap,sysfsdev=/sys/devices/vfio_ap/matrix/$uuid1 ...
+
+7. Start Guest2:
+
+ /usr/bin/qemu-system-s390x ... -cpu host,ap=on,apqci=on,apft=on \
+ -device vfio-ap,sysfsdev=/sys/devices/vfio_ap/matrix/$uuid2 ...
+
+7. Start Guest3:
+
+ /usr/bin/qemu-system-s390x ... -cpu host,ap=on,apqci=on,apft=on \
+ -device vfio-ap,sysfsdev=/sys/devices/vfio_ap/matrix/$uuid3 ...
+
+When the guest is shut down, the mediated matrix devices may be removed.
+
+Using our example again, to remove the mediated matrix device $uuid1:
+
+ /sys/devices/vfio_ap/matrix/
+ --- [mdev_supported_types]
+ ------ [vfio_ap-passthrough]
+ --------- [devices]
+ ------------ [$uuid1]
+ --------------- remove
+
+
+ echo 1 > remove
+
+ This will remove all of the mdev matrix device's sysfs structures including
+ the mdev device itself. To recreate and reconfigure the mdev matrix device,
+ all of the steps starting with step 3 will have to be performed again. Note
+ that the remove will fail if a guest using the mdev is still running.
+
+ It is not necessary to remove an mdev matrix device, but one may want to
+ remove it if no guest will use it during the remaining lifetime of the linux
+ host. If the mdev matrix device is removed, one may want to also reconfigure
+ the pool of adapters and queues reserved for use by the default drivers.
+
+Limitations
+===========
+* The KVM/kernel interfaces do not provide a way to prevent restoring an APQN
+ to the default drivers pool of a queue that is still assigned to a mediated
+ device in use by a guest. It is incumbent upon the administrator to
+ ensure there is no mediated device in use by a guest to which the APQN is
+ assigned lest the host be given access to the private data of the AP queue
+ device, such as a private key configured specifically for the guest.
+
+* Dynamically modifying the AP matrix for a running guest (which would amount to
+ hot(un)plug of AP devices for the guest) is currently not supported
+
+* Live guest migration is not supported for guests using AP devices.

VNC server is calling sasl_server_init() during startup of QEMU, even
if SASL auth has not been enabled.
This may create undesirable warnings like "Could not find keytab file:
/etc/qemu/krb5.tab" when the user didn't configure SASL on host and
started VNC server.
Instead, only initialize SASL when needed. Note that HMP/QMP "change
vnc" calls vnc_display_open() again, which will initialize SASL if
needed.
Fix assignment in if condition, while touching this code.

Commit bc37b06a5 added NBD_CMD_CACHE support, but used the wrong value
for NBD_FLAG_SEND_CACHE flag for negotiation. That commit picked bit 8,
which had already been assigned by the NBD specification to mean
NBD_FLAG_CAN_MULTI_CONN, and which was already implemented in the
Linux kernel as a part of stable userspace-kernel API since 4.10:
"bit 8, NBD_FLAG_CAN_MULTI_CONN: Indicates that the server operates
entirely without cache, or that the cache it uses is shared among all
connections to the given device. In particular, if this flag is
present, then the effects of NBD_CMD_FLUSH and NBD_CMD_FLAG_FUA
MUST be visible across all connections when the server sends its reply
to that command to the client. In the absense of this flag, clients
SHOULD NOT multiplex their commands over more than one connection to
the export.
...
bit 10, NBD_FLAG_SEND_CACHE: documents that the server understands
NBD_CMD_CACHE; however, note that server implementations exist
which support the command without advertising this bit, and
conversely that this bit does not guarantee that the command will
succeed or have an impact."
Consequences:
- a client trying to use NBD_CMD_CACHE per the NBD spec will not
see the feature as available from a qemu 3.0 server (not fatal,
clients already have to be prepared for caching to not exist)
- a client accidentally coded to the qemu 3.0 bit value instead
of following the spec may interpret NBD_CMD_CACHE as being available
when it is not (probably not fatal, the spec says the server should
gracefully fail unknown commands, and that clients of NBD_CMD_CACHE
should be prepared for failure even when the feature is advertised);
such clients are unlikely (perhaps only in unreleased Virtuozzo code),
and will disappear over time
- a client prepared to use multiple connections based on
NBD_FLAG_CAN_MULTI_CONN may cause data corruption when it assumes
that caching is consistent when in reality qemu 3.0 did not have
a consistent cache. Partially mitigated by using read-only
connections (where nothing needs to be flushed, so caching is
indeed consistent) or when using qemu-nbd with the default -e 1
(at most one client at a time); visible only when using -e 2 or
more for a writable export.
Thus the commit fixes negotiation flag in QEMU according to the
specification.

In qemu_laio_process_completions_and_submit, the AioContext is acquired
before the ioq_submit iteration and after qemu_laio_process_completions,
but the latter is not thread safe either.
This change avoids a number of random crashes when the Main Thread and
an IO Thread collide processing completions for the same AioContext.
This is an example of such crash:
- The IO Thread is trying to acquire the AioContext at aio_co_enter,
which evidences that it didn't lock it before:

AIO Coroutines shouldn't by managed by an AioContext different than the
one assigned when they are created. aio_co_enter avoids entering a
coroutine from a different AioContext, calling aio_co_schedule instead.
Scheduled coroutines are then entered by co_schedule_bh_cb using
qemu_coroutine_enter, which just calls qemu_aio_coroutine_enter with the
current AioContext obtained with qemu_get_current_aio_context.
Eventually, co->ctx will be set to the AioContext passed as an argument
to qemu_aio_coroutine_enter.
This means that, if an IO Thread's AioConext is being processed by the
Main Thread (due to aio_poll being called with a BDS AioContext, as it
happens in AIO_WAIT_WHILE among other places), the AioContext from some
coroutines may be wrongly replaced with the one from the Main Thread.
This is the root cause behind some crashes, mainly triggered by the
drain code at block/io.c. The most common are these abort and failed
assertion:
util/async.c:aio_co_schedule
456 if (scheduled) {
457 fprintf(stderr,
458 "%s: Co-routine was already scheduled in '%s'\n",
459 __func__, scheduled);
460 abort();
461 }
util/qemu-coroutine-lock.c:
286 assert(mutex->holder == self);
But it's also known to cause random errors at different locations, and
even SIGSEGV with broken coroutine backtraces.
By using qemu_aio_coroutine_enter directly in co_schedule_bh_cb, we can
pass the correct AioContext as an argument, making sure co->ctx is not
wrongly altered.

All callers have acquired ctx already. Doing that again results in
aio_poll() hang. This fixes the problem that a BDRV_POLL_WHILE() in the
callback cannot make progress because ctx is recursively locked, for
example, when drive-backup finishes.
There are two callers of job_finalize():
fam@lemon:~/work/qemu [master]$ git grep -w -A1 '^\s*job_finalize'
blockdev.c: job_finalize(&job->job, errp);
blockdev.c- aio_context_release(aio_context);
--
job-qmp.c: job_finalize(job, errp);
job-qmp.c- aio_context_release(aio_context);
--
tests/test-blockjob.c: job_finalize(&job->job, &error_abort);
tests/test-blockjob.c- assert(job->job.status == JOB_STATUS_CONCLUDED);
Ignoring the test, it's easy to see both callers to job_finalize (and
job_do_finalize) have acquired the context.

job_completed() had a problem with double locking that was recently
fixed independently by two different commits:
"job: Fix nested aio_poll() hanging in job_txn_apply"
"jobs: add exit shim"
One fix removed the first aio_context_acquire(), the other fix removed
the other one. Now we have a bug again and the code is run without any
locking.
Add it back in one of the places.

In the context of draining a BDS, the .drained_poll callback of block
jobs is called. If this returns true (i.e. there is still some activity
pending), the drain operation may call aio_poll() with blocking=true to
wait for completion.
As soon as the pending activity is completed and the job finally arrives
in a quiescent state (i.e. its coroutine either yields with busy=false
or terminates), the block job must notify the aio_poll() loop to wake
up, otherwise we get a deadlock if both are running in different
threads.

Even if AIO_WAIT_WHILE() is called in the home context of the
AioContext, we still want to allow the condition to change depending on
other threads as long as they kick the AioWait. Specfically block jobs
can be running in an I/O thread and should then be able to kick a drain
in the main loop context.

job_finish_sync(). test-blockjob should do the same when it calls the

job_finish_sync() needs to release the AioContext lock of the job before
calling aio_poll(). Otherwise, callbacks called by aio_poll() would
possibly take the lock a second time and run into a deadlock with a
nested AIO_WAIT_WHILE() call.
Also, job_drain() without aio_poll() isn't necessarily enough to make
progress on a job, it could depend on bottom halves to be executed.
Combine both open-coded while loops into a single AIO_WAIT_WHILE() call
that solves both of these problems.

This is a regression test for a deadlock that occurred in block job
completion callbacks (via job_defer_to_main_loop) because the AioContext
lock was taken twice: once in job_finish_sync() and then again in
job_defer_to_main_loop_bh(). This would cause AIO_WAIT_WHILE() to hang.

bdrv_do_drained_begin/end() assume that they are called with the
AioContext lock of bs held. If we call drain functions from a coroutine
with the AioContext lock held, we yield and schedule a BH to move out of
coroutine context. This means that the lock for the home context of the
coroutine is released and must be re-acquired in the bottom half.

A bdrv_drain operation must ensure that all parents are quiesced, this
includes BlockBackends. Otherwise, callbacks called by requests that are
completed on the BDS layer, but not quite yet on the BlockBackend layer

blk_unref() first decreases the refcount of the BlockBackend and calls
blk_delete() if the refcount reaches zero. Requests can still be in
flight at this point, they are only drained during blk_delete():
At this point, arbitrary callbacks can run. If any callback takes a
temporary BlockBackend reference, it will first increase the refcount to
1 and then decrease it to 0 again, triggering another blk_delete(). This
will cause a use-after-free crash in the outer blk_delete().
Fix it by draining the BlockBackend before decreasing to refcount to 0.
Assert in blk_ref() that it never takes the first refcount (which would
mean that the BlockBackend is already being deleted).

Request callbacks can do pretty much anything, including operations that
will yield from the coroutine (such as draining the backend). In that
case, a decreased in_flight would be visible to other code and could
lead to a drain completing while the callback hasn't actually completed
yet.
Note that reordering these operations forbids calling drain directly
inside an AIO callback. As Paolo explains, indirectly calling it is
okay:
- Calling it through a coroutine is okay, because then
bdrv_drained_begin() goes through bdrv_co_yield_to_drain() and you
have in_flight=2 when bdrv_co_yield_to_drain() yields, then soon
in_flight=1 when the aio_co_wake() in the AIO callback completes, then
in_flight=0 after the bottom half starts.
- Calling it through a bottom half would be okay too, as long as the AIO
callback remembers to do inc_in_flight/dec_in_flight just like
bdrv_co_yield_to_drain() and bdrv_co_drain_bh_cb() do
A few more important cases that come to mind:
- A coroutine that yields because of I/O is okay, with a sequence
similar to bdrv_co_yield_to_drain().
- A coroutine that yields with no I/O pending will correctly decrease
in_flight to zero before yielding.
- Calling more AIO from the callback won't overflow the counter just
because of mutual recursion, because AIO functions always yield at
least once before invoking the callback.

Block jobs claim in .drained_poll() that they are in a quiescent state
as soon as job->deferred_to_main_loop is true. This is obviously wrong,
they still have a completion BH to run. We only get away with this
because commit 91af091f923 added an unconditional aio_poll(false) to the
drain functions, but this is bypassing the regular drain mechanisms.
However, just removing this and telling that the job is still active
doesn't work either: The completion callbacks themselves call drain
functions (directly, or indirectly with bdrv_reopen), so they would
deadlock then.
As a better lie, tell that the job is active as long as the BH is
pending, but falsely call it quiescent from the point in the BH when the
completion callback is called. At this point, nested drain calls won't
deadlock because they ignore the job, and outer drains will wait for the
job to really reach a quiescent state because the callback is already
running.

bdrv_drain_poll_top_level() was buggy because it didn't release the
AioContext lock of the node to be drained before calling aio_poll().
This way, callbacks called by aio_poll() would possibly take the lock a
second time and run into a deadlock with a nested AIO_WAIT_WHILE() call.
However, it turns out that the aio_poll() call isn't actually needed any
more. It was introduced in commit 91af091f923, which is effectively
reverted by this patch. The cases it was supposed to fix are now covered
by bdrv_drain_poll(), which waits for block jobs to reach a quiescent
state.

This is a regression test for a deadlock that could occur in callbacks
called from the aio_poll() in bdrv_drain_poll_top_level(). The
AioContext lock wasn't released and therefore would be taken a second
time in the callback. This would cause a possible AIO_WAIT_WHILE() in
the callback to hang.

Amongst others, job_finalize_single() calls the .prepare/.commit/.abort
callbacks of the individual job driver. Recently, their use was adapted
for all block jobs so that they involve code calling AIO_WAIT_WHILE()
now. Such code must be called under the AioContext lock for the
respective job, but without holding any other AioContext lock.

This adds tests for calling AIO_WAIT_WHILE() in the .commit and .abort
callbacks. Both reasons why .abort could be called for a single job are
tested: Either .run or .prepare could return an error.

Commit 89bd030533e changed the test case from using job_sleep_ns() to
using qemu_co_sleep_ns() instead. Also, block_job_sleep_ns() became
job_sleep_ns() in commit 5d43e86e11f.
In both cases, some comments in the test case were not updated. Do that
now.

When draining a block node, we recurse to its parent and for subtree
drains also to its children. A single AIO_WAIT_WHILE() is then used to
wait for bdrv_drain_poll() to become true, which depends on all of the
nodes we recursed to. However, if the respective child or parent becomes
quiescent and calls bdrv_wakeup(), only the AioWait of the child/parent
is checked, while AIO_WAIT_WHILE() depends on the AioWait of the
original node.
Fix this by using a single AioWait for all callers of AIO_WAIT_WHILE().
This may mean that the draining thread gets a few more unnecessary
wakeups because an unrelated operation got completed, but we already
wake it up when something _could_ have changed rather than only if it
has certainly changed.
Apart from that, drain is a slow path anyway. In theory it would be
possible to use wakeups more selectively and still correctly, but the
gains are likely not worth the additional complexity. In fact, this
patch is a nice simplification for some places in the code.

Subject: test-bdrv-drain: Test draining job source child and parent

O-Subject: [RHEL-8 qemu-kvm PATCH 44/44] test-bdrv-drain: Test draining job source child and parent
Bugzilla: 1637976
RH-Acked-by: Max Reitz <mreitz@redhat.com>
RH-Acked-by: John Snow <jsnow@redhat.com>

For the block job drain test, don't only test draining the source and
the target node, but create a backing chain for the source
(source_backing <- source <- source_overlay) and test draining each of
the nodes in it.
When using iothreads, the source node (and therefore the job) is in a
different AioContext than the drain, which happens from the main
thread. This way, the main thread waits in AIO_WAIT_WHILE() for the
iothread to make process and aio_wait_kick() is required to notify it.
The test validates that calling bdrv_wakeup() for a child or a parent
node will actually notify AIO_WAIT_WHILE() instead of letting it hang.
Increase the sleep time a bit (to 1 ms) because the test case is racy
and with the shorter sleep, it didn't reproduce the bug it is supposed
to test for me under 'rr record -n'.
This was because bdrv_drain_invoke_entry() (in the main thread) was only
called after the job had already reached the pause point, so we got a
bdrv_dec_in_flight() from the main thread and the additional
aio_wait_kick() when the job becomes idle (that we really wanted to test
here) wasn't even necessary any more to make progress.
