From 431955e872aa010376b1f94665908c2ba8194b44 Mon Sep 17 00:00:00 2001

Subject: Initial redhat build
This patch introduces redhat build structure in redhat subdirectory. In addition,
several issues are fixed in QEMU tree:
- Change of app name for sasl_server_init in VNC code from qemu to qemu-kvm
- As we use qemu-kvm as name in all places, this is updated to be consistent
- Man page renamed from qemu to qemu-kvm
- man page is installed using make install so we have to fix it in qemu tree
We disable make check due to issues with some of the tests.
This rebase is based on qemu-kvm-5.2.0-16.el9

+QEMU tracing using systemtap-initscript
+---------------------------------------
+
+You can capture QEMU trace data all the time using systemtap-initscript. This
+uses SystemTap's flight recorder mode to trace all running guests to a
+fixed-size buffer on the host. Old trace entries are overwritten by new
+entries when the buffer size wraps.
+
+1. Install the systemtap-initscript package:
+ # yum install systemtap-initscript
+
+2. Install the systemtap scripts and the conf file:
+ # cp /usr/share/qemu-kvm/systemtap/script.d/qemu_kvm.stp /etc/systemtap/script.d/
+ # cp /usr/share/qemu-kvm/systemtap/conf.d/qemu_kvm.conf /etc/systemtap/conf.d/
+
+The set of trace events to enable is given in qemu_kvm.stp. This SystemTap
+script can be customized to add or remove trace events provided in
+/usr/share/systemtap/tapset/qemu-kvm-simpletrace.stp.
+
+SystemTap customizations can be made to qemu_kvm.conf to control the flight
+recorder buffer size and whether to store traces in memory only or disk too.
+See stap(1) for option documentation.
+
+3. Start the systemtap service.
+ # service systemtap start qemu_kvm
+
+4. Make the service start at boot time.
+ # chkconfig systemtap on
+
+5. Confirm that the service works.
+ # service systemtap status qemu_kvm
+ qemu_kvm is running...
+
+When you want to inspect the trace buffer, perform the following steps:
+
+1. Dump the trace buffer.
+ # staprun -A qemu_kvm >/tmp/trace.log
+
+2. Start the systemtap service because the preceding step stops the service.
+ # service systemtap start qemu_kvm
+
+3. Translate the trace record to readable format.
+ # /usr/share/qemu-kvm/simpletrace.py --no-header /usr/share/qemu-kvm/trace-events /tmp/trace.log

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

+QEMU tracing using systemtap-initscript
+---------------------------------------
+
+You can capture QEMU trace data all the time using systemtap-initscript. This
+uses SystemTap's flight recorder mode to trace all running guests to a
+fixed-size buffer on the host. Old trace entries are overwritten by new
+entries when the buffer size wraps.
+
+1. Install the systemtap-initscript package:
+ # yum install systemtap-initscript
+
+2. Install the systemtap scripts and the conf file:
+ # cp /usr/share/qemu-kvm/systemtap/script.d/qemu_kvm.stp /etc/systemtap/script.d/
+ # cp /usr/share/qemu-kvm/systemtap/conf.d/qemu_kvm.conf /etc/systemtap/conf.d/
+
+The set of trace events to enable is given in qemu_kvm.stp. This SystemTap
+script can be customized to add or remove trace events provided in
+/usr/share/systemtap/tapset/qemu-kvm-simpletrace.stp.
+
+SystemTap customizations can be made to qemu_kvm.conf to control the flight
+recorder buffer size and whether to store traces in memory only or disk too.
+See stap(1) for option documentation.
+
+3. Start the systemtap service.
+ # service systemtap start qemu_kvm
+
+4. Make the service start at boot time.
+ # chkconfig systemtap on
+
+5. Confirm that the service works.
+ # service systemtap status qemu_kvm
+ qemu_kvm is running...
+
+When you want to inspect the trace buffer, perform the following steps:
+
+1. Dump the trace buffer.
+ # staprun -A qemu_kvm >/tmp/trace.log
+
+2. Start the systemtap service because the preceding step stops the service.
+ # service systemtap start qemu_kvm
+
+3. Translate the trace record to readable format.
+ # /usr/share/qemu-kvm/simpletrace.py --no-header /usr/share/qemu-kvm/trace-events /tmp/trace.log

RHEL may need to override some default property inherited from upstream.
This is currently handled in the class_options() function of the latest
machine type, and thus the defaults need to be carried around each time
we add a new RHEL machine.
Override the defaults in a dedicated function to be called by the
latest RHEL machine type.

Note that we did not publish a rhel-8.3.0 machine on s390x, so we
need to add the respective hw_compat entry in the rhel-8.2.0 machine.
Also, the hw_compat entry for 8.1 was missing; however, the contents
there are not relevant for s390x.

Subject: block/vpc: Make vpc_open() read the full dynamic header
The dynamic header's size is 1024 bytes.
vpc_open() reads only the 512 bytes of the dynamic header into buf[].
Works, because it doesn't actually access the second half. However, a
colleague told me that GCC 11 warns:
../block/vpc.c:358:51: error: array subscript 'struct VHDDynDiskHeader[0]' is partly outside array bounds of 'uint8_t[512]' [-Werror=array-bounds]
Clean up to read the full header.
Rename buf[] to dyndisk_header_buf[] while there.

Subject: s390x: Use strpadcpy for copying vm name
Using strncpy with length equal to the size of target array, GCC 11
reports following warning:
warning: '__builtin_strncpy' specified bound 256 equals destination size [-Wstringop-truncation]
We can prevent this warning by using strpadcpy that copies string
up to specified length, zeroes target array after copied string
and does not raise warning when length is equal to target array
size (and ending '\0' is discarded).

Subject: net/eth: Simplify _eth_get_rss_ex_dst_addr()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The length field is already contained in the ip6_ext_hdr structure.
Check it direcly in eth_parse_ipv6_hdr() before calling
_eth_get_rss_ex_dst_addr(), which gets a bit simplified.

In eth_parse_ipv6_hdr() we called iov_to_buf() to fill the 2 bytes of
the 'ext_hdr' buffer, then _eth_get_rss_ex_dst_addr() tries to access
beside the 2 filled bytes.
Fix by reworking the function, filling the full rt_hdr buffer on the
stack calling iov_to_buf() again.

NVMe drive cannot be shrunk.
Since commit c80d8b06cfa we can use the @exact parameter (set
to false) to return success if the block device is larger than
the requested offset (even if we can not be shrunk).
Use this parameter to implement the NVMe truncate() coroutine,
similarly how it is done for the iscsi and file-posix drivers
(see commit 82325ae5f2f "Evaluate @exact in protocol drivers").

to use non-PIE objects and fail to link. Therefore, upstream
QEMU looks at the meson version in order to decide between
b_staticpic=false and b_staticpic=$pie.
Unfortunately, b_staticpic=$pie still has a negative effect
on performance when you QEMU is compiled with --enable-pie
like RHEL does. Therefore, we have backported the fix
to Meson 0.55.3-3.el8. We can require it and unconditionally
use b_staticpic=false.
The patch is RHEL-specific, but a similar change is included
in the larger patch for "meson: switch minimum meson version to
0.56.0".

From: Greg Kurz <groug@kaod.org>
Running a guest with 128 NUMA nodes crashes QEMU:
../../util/error.c:59: error_setv: Assertion `*errp == NULL' failed.
The crash happens when setting the FWNMI migration blocker:
2861 if (spapr_get_cap(spapr, SPAPR_CAP_FWNMI) == SPAPR_CAP_ON) {
2862 /* Create the error string for live migration blocker */
2863 error_setg(&spapr->fwnmi_migration_blocker,
2864 "A machine check is being handled during migration. The handler"
2865 "may run and log hardware error on the destination");
2866 }
Inspection reveals that papr->fwnmi_migration_blocker isn't NULL:
(gdb) p spapr->fwnmi_migration_blocker
$1 = (Error *) 0x8000000004000000
Since this is the only place where papr->fwnmi_migration_blocker is
set, this means someone wrote there in our back. Further analysis
points to spapr_numa_associativity_init(), especially the part
that initializes the associative arrays for NVLink GPUs:
max_nodes_with_gpus = nb_numa_nodes + NVGPU_MAX_NUM;
ie. max_nodes_with_gpus = 128 + 6, but the array isn't sized to
accommodate the 6 extra nodes:
struct SpaprMachineState {
.
.
.
uint32_t numa_assoc_array[MAX_NODES][NUMA_ASSOC_SIZE];
Error *fwnmi_migration_blocker;
};
and the following loops happily overwrite spapr->fwnmi_migration_blocker,
and probably more:
for (i = nb_numa_nodes; i < max_nodes_with_gpus; i++) {
spapr->numa_assoc_array[i][0] = cpu_to_be32(MAX_DISTANCE_REF_POINTS);
for (j = 1; j < MAX_DISTANCE_REF_POINTS; j++) {
uint32_t gpu_assoc = smc->pre_5_1_assoc_refpoints ?
SPAPR_GPU_NUMA_ID : cpu_to_be32(i);
spapr->numa_assoc_array[i][j] = gpu_assoc;
}
spapr->numa_assoc_array[i][MAX_DISTANCE_REF_POINTS] = cpu_to_be32(i);
}
Fix the size of the array. This requires "hw/ppc/spapr.h" to see
NVGPU_MAX_NUM. Including "hw/pci-host/spapr.h" introduces a
circular dependency that breaks the build, so this moves the
definition of NVGPU_MAX_NUM to "hw/ppc/spapr.h" instead.

Allow the reordering of the PCIe capabilities for MSI around the PCIe
capability.
This changed incompatibly way back in QEMU 2.7 and in RHEL we fixed
it up in bz 1447874 unconditionally putting it back.
The xhci code got reorganised between 5.0 and 5.2; and we lost this
fixup on rebase.
This time, add it as a property, and enable the property for old
machine types; this will allow us to drop this patch once the
old machine types go.

This allows us to differentiate between regular IOMMU map/unmap events
and DEVIOTLB unmap. Doing so, notifiers that only need device IOTLB
invalidations will not receive regular IOMMU unmappings.
Adapt intel and vhost to use it.

Although they didn't reach the notifier because of the filtering in
memory_region_notify_iommu_one, the vt-d was still splitting huge
memory invalidations in chunks. Skipping it.
This improves performance in case of netperf with vhost-net:
* TCP_STREAM: From 1923.6Mbit/s to 2175.13Mbit/s (13%)

Device IOTLB invalidations can unmap arbitrary ranges, eiter outside of
the memory region or even [0, ~0ULL] for all the space. The assertion
could be hit by a guest, and rhel7 guest effectively hit it.

Since b1b0393c3c5 the pvpanic test checks for a different
result (3) expecting it to get that on new machine types.
But, downstream, our 'pc' machine type is old, so switch the
test to q35, so it gets the new behaviour it's expecting.

O-Subject: [RHEL-AV-8.4.0 qemu-kvm PATCH 1/1] memory: clamp cached translation in case it points to an MMIO region
Bugzilla: 1904392
RH-Acked-by: Danilo de Paula <ddepaula@redhat.com>
RH-Acked-by: Dr. David Alan Gilbert <dgilbert@redhat.com>
RH-Acked-by: Thomas Huth <thuth@redhat.com>
From: Paolo Bonzini <pbonzini@redhat.com>
In using the address_space_translate_internal API, address_space_cache_init
forgot one piece of advice that can be found in the code for
address_space_translate_internal:
/* MMIO registers can be expected to perform full-width accesses based only
* on their address, without considering adjacent registers that could
* decode to completely different MemoryRegions. When such registers
* exist (e.g. I/O ports 0xcf8 and 0xcf9 on most PC chipsets), MMIO
* regions overlap wildly. For this reason we cannot clamp the accesses
* here.
*
* If the length is small (as is the case for address_space_ldl/stl),
* everything works fine. If the incoming length is large, however,
* the caller really has to do the clamping through memory_access_size.
*/
address_space_cache_init is exactly one such case where "the incoming length
is large", therefore we need to clamp the resulting length---not to
memory_access_size though, since we are not doing an access yet, but to
the size of the resulting section. This ensures that subsequent accesses
to the cached MemoryRegionSection will be in range.
With this patch, the enclosed testcase notices that the used ring does
not fit into the MSI-X table and prints a "qemu-system-x86_64: Cannot map used"
error.

Drop IPv6 message shorter than what's mentioned in the payload
length header (+ the size of the IPv6 header). They're invalid an could
lead to data leakage in icmp6_send_echoreply().

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

Some graphs may contain an indirect reference to the first BDS in the
chain that can be reached while walking it bottom->up from one its
children.
Doubling-processing of a BDS is especially problematic for the
aio_notifiers, as they might attempt to work on both the old and the
new AIO contexts.
To avoid this problem, add every child and parent to the ignore list
before actually processing them.

RH-Acked-by: Eric Blake <eblake@redhat.com>
The documentation for bdrv_set_aio_context_ignore() states this:
* The caller must own the AioContext lock for the old AioContext of bs, but it
* must not own the AioContext lock for new_context (unless new_context is the
* same as the current context of bs).
As blk_set_aio_context() makes use of this function, this rule also
applies to it.
Fix all occurrences where this rule wasn't honored.

The driver is supposed to honor the blk_size field but the protocol
still uses 512-byte sector numbers. It is incorrect to multiply
req->sector_num by blk_size.
VIRTIO 1.1 5.2.5 Device Initialization says:
blk_size can be read to determine the optimal sector size for the
driver to use. This does not affect the units used in the protocol
(always 512 bytes), but awareness of the correct value can affect
performance.

Use VIRTIO_BLK_SECTOR_BITS and VIRTIO_BLK_SECTOR_SIZE when dealing with
virtio-blk sector numbers. Although the values happen to be the same as
BDRV_SECTOR_BITS and BDRV_SECTOR_SIZE, they are conceptually different.
This makes it clearer when we are dealing with virtio-blk sector units.
Use VIRTIO_BLK_SECTOR_BITS in vu_blk_initialize_config(). Later patches
will use it the new constants the virtqueue request processing code
path.

Move blk_exp_close_all() from bdrv_close() to qemu_cleanup(), before
bdrv_drain_all_begin().
Export drivers may have coroutines yielding at some point in the block
layer, so we need to shut them down before draining the block layer,
as otherwise they may get stuck blk_wait_while_drained().

From: Roman Kagan <rvkagan@yandex-team.ru>
When the reconnect in NBD client is in progress, the iochannel used for
NBD connection doesn't exist. Therefore an attempt to detach it from
the aio_context of the parent BlockDriverState results in a NULL pointer
dereference.
The problem is triggerable, in particular, when an outgoing migration is
about to finish, and stopping the dataplane tries to move the
BlockDriverState from the iothread aio_context to the main loop. If the
NBD connection is lost before this point, and the NBD client has entered
the reconnect procedure, QEMU crashes:

Fix it by checking that the iochannel is non-null before trying to
detach it from the aio_context. If it is null, no detaching is needed,
and it will get reattached in the proper aio_context once the connection
is reestablished.

Bugzilla: 1887883

From: Roman Kagan <rvkagan@yandex-team.ru>
When an NBD block driver state is moved from one aio_context to another
(e.g. when doing a drain in a migration thread),
nbd_client_attach_aio_context_bh is executed that enters the connection
coroutine.
However, the assumption that ->connection_co is always present here
appears incorrect: the connection may have encountered an error other
than -EIO in the underlying transport, and thus may have decided to quit
rather than keep trying to reconnect, and therefore it may have
terminated the connection coroutine. As a result an attempt to reassign
the client in this state (NBD_CLIENT_QUIT) to a different aio_context
leads to a null pointer dereference:

Fix it by checking that the connection coroutine is non-null before
trying to enter it. If it is null, no entering is needed, as the
connection is probably going down anyway.

Document the qemu-storage-daemon tool. Most of the command-line options
are identical to their QEMU counterparts. Perhaps Sphinx hxtool
integration could be extended to extract documentation for individual
command-line options so they can be shared. For now the
qemu-storage-daemon simply refers to the qemu(1) man page where the
command-line options are identical.

+QEMU Storage Daemon
+===================
+
+Synopsis
+--------
+
+**qemu-storage-daemon** [options]
+
+Description
+-----------
+
+qemu-storage-daemon provides disk image functionality from QEMU, qemu-img, and
+qemu-nbd in a long-running process controlled via QMP commands without running
+a virtual machine. It can export disk images, run block job operations, and
+perform other disk-related operations. The daemon is controlled via a QMP
+monitor and initial configuration from the command-line.
+
+The daemon offers the following subset of QEMU features:
+
+* Block nodes
+* Block jobs
+* Block exports
+* Throttle groups
+* Character devices
+* Crypto and secrets
+* QMP
+* IOThreads
+
+Commands can be sent over a QEMU Monitor Protocol (QMP) connection. See the
+:manpage:`qemu-storage-daemon-qmp-ref(7)` manual page for a description of the
+commands.
+
+The daemon runs until it is stopped using the ``quit`` QMP command or
+SIGINT/SIGHUP/SIGTERM.
+
+**Warning:** Never modify images in use by a running virtual machine or any
+other process; this may destroy the image. Also, be aware that querying an
+image that is being modified by another process may encounter inconsistent
+state.
+
+Options
+-------
+
+.. program:: qemu-storage-daemon
+
+Standard options:
+
+.. option:: -h, --help
+
+ Display help and exit
+
+.. option:: -V, --version
+
+ Display version information and exit
+
+.. option:: -T, --trace [[enable=]PATTERN][,events=FILE][,file=FILE]
+
+ .. include:: ../qemu-option-trace.rst.inc
+
+.. option:: --blockdev BLOCKDEVDEF
+
+ is a block node definition. See the :manpage:`qemu(1)` manual page for a
+ description of block node properties and the :manpage:`qemu-block-drivers(7)`
+ manual page for a description of driver-specific parameters.
+
+.. option:: --chardev CHARDEVDEF
+
+ is a character device definition. See the :manpage:`qemu(1)` manual page for
+ a description of character device properties. A common character device
+ definition configures a UNIX domain socket::
+
+ --chardev socket,id=char1,path=/tmp/qmp.sock,server,nowait
+
+.. option:: --export [type=]nbd,id=<id>,node-name=<node-name>[,name=<export-name>][,writable=on|off][,bitmap=<name>]
+ --export [type=]vhost-user-blk,id=<id>,node-name=<node-name>,addr.type=unix,addr.path=<socket-path>[,writable=on|off][,logical-block-size=<block-size>][,num-queues=<num-queues>]
+ --export [type=]vhost-user-blk,id=<id>,node-name=<node-name>,addr.type=fd,addr.str=<fd>[,writable=on|off][,logical-block-size=<block-size>][,num-queues=<num-queues>]
+
+ is a block export definition. ``node-name`` is the block node that should be
+ exported. ``writable`` determines whether or not the export allows write
+ requests for modifying data (the default is off).
+
+ The ``nbd`` export type requires ``--nbd-server`` (see below). ``name`` is
+ the NBD export name. ``bitmap`` is the name of a dirty bitmap reachable from
+ the block node, so the NBD client can use NBD_OPT_SET_META_CONTEXT with the
+ metadata context name "qemu:dirty-bitmap:BITMAP" to inspect the bitmap.
+
+ The ``vhost-user-blk`` export type takes a vhost-user socket address on which
+ it accept incoming connections. Both
+ ``addr.type=unix,addr.path=<socket-path>`` for UNIX domain sockets and
+ ``addr.type=fd,addr.str=<fd>`` for file descriptor passing are supported.
+ ``logical-block-size`` sets the logical block size in bytes (the default is
+ 512). ``num-queues`` sets the number of virtqueues (the default is 1).
+
+.. option:: --monitor MONITORDEF
+
+ is a QMP monitor definition. See the :manpage:`qemu(1)` manual page for
+ a description of QMP monitor properties. A common QMP monitor definition
+ configures a monitor on character device ``char1``::
+
+ --monitor chardev=char1
+
+.. option:: --nbd-server addr.type=inet,addr.host=<host>,addr.port=<port>[,tls-creds=<id>][,tls-authz=<id>][,max-connections=<n>]
+ --nbd-server addr.type=unix,addr.path=<path>[,tls-creds=<id>][,tls-authz=<id>][,max-connections=<n>]
+
+ is a server for NBD exports. Both TCP and UNIX domain sockets are supported.
+ TLS encryption can be configured using ``--object`` tls-creds-* and authz-*
+ secrets (see below).
+
+ To configure an NBD server on UNIX domain socket path ``/tmp/nbd.sock``::
+
+ --nbd-server addr.type=unix,addr.path=/tmp/nbd.sock
+
+.. option:: --object help
+ --object <type>,help
+ --object <type>[,<property>=<value>...]
+
+ is a QEMU user creatable object definition. List object types with ``help``.
+ List object properties with ``<type>,help``. See the :manpage:`qemu(1)`
+ manual page for a description of the object properties.
+
+Examples
+--------
+Launch the daemon with QMP monitor socket ``qmp.sock`` so clients can execute
+QMP commands::
+
+ $ qemu-storage-daemon \
+ --chardev socket,path=qmp.sock,server,nowait,id=char1 \
+ --monitor chardev=char1
+
+Export raw image file ``disk.img`` over NBD UNIX domain socket ``nbd.sock``::
+
+ $ qemu-storage-daemon \
+ --blockdev driver=file,node-name=disk,filename=disk.img \
+ --nbd-server addr.type=unix,addr.path=nbd.sock \
+ --export type=nbd,id=export,node-name=disk,writable=on
+
+Export a qcow2 image file ``disk.qcow2`` as a vhosts-user-blk device over UNIX
+domain socket ``vhost-user-blk.sock``::
+
+ $ qemu-storage-daemon \
+ --blockdev driver=file,node-name=file,filename=disk.qcow2 \
+ --blockdev driver=qcow2,node-name=qcow2,file=file \
+ --export type=vhost-user-blk,id=export,addr.type=unix,addr.path=vhost-user-blk.sock,node-name=qcow2

O-Subject: [RHEL-AV-8.4.0 qemu-kvm PATCH 1/5] docs: generate qemu-storage-daemon-qmp-ref(7) man page
Bugzilla: 1901323
RH-Acked-by: Sergio Lopez Pascual <slp@redhat.com>
RH-Acked-by: Stefan Hajnoczi <stefanha@redhat.com>
RH-Acked-by: Max Reitz <mreitz@redhat.com>
From: Stefan Hajnoczi <stefanha@redhat.com>
Although individual qemu-storage-daemon QMP commands are identical to
QEMU QMP commands, qemu-storage-daemon only supports a subset of QEMU's
QMP commands. Generate a manual page of just the commands supported by
qemu-storage-daemon so that users know exactly what is available in
qemu-storage-daemon.
Add an h1 heading in storage-daemon/qapi/qapi-schema.json so that
block-core.json is at the h2 heading level.

It was only set "once", and with the wrong value. As far as I can see,
libvirt still don't use it.

Two things, at this point:
* n->primary_device_id has to be set, otherwise
virtio_net_find_primary don't work. So we have a leak here.
* it has to be exactly the same that prim_dev->id because what
qdev_find_recursive() does is just compare this two values.
So remove the unneeded assignment and leaky bits.

check anywhere else.

We didn't use at all the -1 value, and we don't really care. It was
only used for the cases when this is not the device that we are
searching for. And in that case we should not hide the device.
Once there, simplify virtio-Snet_primary_should_be_hidden.

When handling guest range-based IOTLB invalidation, we should decode the TG
field into the corresponding translation granule size so that we can pass
the correct invalidation range to backend. Set @granule to (tg * 2 + 10) to
properly emulate the architecture.

From: Philippe Mathieu-Daudé <f4bug@amsat.org>
Per the ARM Generic Interrupt Controller Architecture specification
(document "ARM IHI 0048B.b (ID072613)"), the SGIINTID field is 4 bit,
not 10:
- 4.3 Distributor register descriptions
- 4.3.15 Software Generated Interrupt Register, GICD_SG
- Table 4-21 GICD_SGIR bit assignments
The Interrupt ID of the SGI to forward to the specified CPU
interfaces. The value of this field is the Interrupt ID, in
the range 0-15, for example a value of 0b0011 specifies
Interrupt ID 3.
Correct the irq mask to fix an undefined behavior (which eventually
lead to a heap-buffer-overflow, see [Buglink]):

SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior ../hw/intc/arm_gic.c:1498:13
This fixes a security issue when running with KVM on Arm with
kernel-irqchip=off. (The default is kernel-irqchip=on, which is
unaffected, and which is also the correct choice for performance.)

Adds the support for AMD 3rd generation processors. The model
display for the new processor will be EPYC-Milan.
Adds the following new feature bits on top of the feature bits from
the first and second generation EPYC models.
pcid : Process context identifiers support
ibrs : Indirect Branch Restricted Speculation
ssbd : Speculative Store Bypass Disable
erms : Enhanced REP MOVSB/STOSB support
fsrm : Fast Short REP MOVSB support
invpcid : Invalidate processor context ID
pku : Protection keys support
svme-addr-chk : SVM instructions address check for #GP handling

After fixing the _UID value for the primary PCI root bridge in
af1b80ae it was discovered that this change updates Windows
configuration in an incompatible way causing network configuration
failure unless DHCP is used. More details provided on the list:
https://lists.gnu.org/archive/html/qemu-devel/2021-02/msg08484.html
This change reverts the _UID update from 1 to 0 for q35 and i440fx
VMs before version 5.2 to maintain the original behaviour when
upgrading.

clean cherrypick +
adding the same quirk to RHEL's pc(7.6)/q35(8.3) machine types
to preserve old UID. pc-q35-rhel8.4.0 will have new UID as defined
by spec (but since it's not been released yet there is no risk of
breaking [non]existing Windows deployments and new installations
should pickup new PCI device enumeration just fine)

Bitmap's source persistence is transported over the migration stream and
the destination mirrors it. In some cases the destination might want to
persist bitmaps which are not persistent on the source (e.g. the result
of merging bitmaps from a number of layers on the source when migrating
into a squashed image) but currently it would need to create another set
of persistent bitmaps and merge them.
This patch adds a 'transform' property to the alias map which allows
overriding the persistence of migrated bitmaps both on the source and
destination sides.

Currently the alias mapping hash stores just strings of the target
objects internally. In further patches we'll be adding another member
which will need to be stored in the map so pass a copy of the whole
BitmapMigrationBitmapAlias QAPI struct into the map.

From: Roman Kagan <rvkagan@yandex-team.ru>
NBD reconnect logic considers the error code from the functions that
read NBD messages to tell if reconnect should be attempted or not: it is
attempted on -EIO, otherwise the client transitions to NBD_CLIENT_QUIT
state (see nbd_channel_error). This error code is propagated from the
primitives like nbd_read.
The problem, however, is that nbd_read itself turns every error into -1
rather than -EIO. As a result, if the NBD server happens to die while
sending the message, the client in QEMU receives less data than it
expects, considers it as a fatal error, and wouldn't attempt
reestablishing the connection.
Fix it by turning every negative return from qio_channel_read_all into
-EIO returned from nbd_read. Apparently that was the original behavior,
but got broken later. Also adjust nbd_readXX to follow.

O-Subject: [RHEL-AV-8.4.0 qemu-kvm PATCH 2/5] nbd/server: Quiesce coroutines on context switch

RH-Acked-by: Max Reitz <mreitz@redhat.com>
RH-Acked-by: Kevin Wolf <kwolf@redhat.com>
RH-Acked-by: Eric Blake <eblake@redhat.com>
When switching between AIO contexts we need to me make sure that both
recv_coroutine and send_coroutine are not scheduled to run. Otherwise,
QEMU may crash while attaching the new context with an error like
this one:
aio_co_schedule: Co-routine was already scheduled in 'aio_co_schedule'
To achieve this we need a local implementation of
'qio_channel_readv_all_eof' named 'nbd_read_eof' (a trick already done
by 'nbd/client.c') that allows us to interrupt the operation and to
know when recv_coroutine is yielding.
With this in place, we delegate detaching the AIO context to the
owning context with a BH ('nbd_aio_detach_bh') scheduled using
'aio_wait_bh_oneshot'. This BH signals that we need to quiesce the
channel by setting 'client->quiescing' to 'true', and either waits for
the coroutine to finish using AIO_WAIT_WHILE or, if it's yielding in
'nbd_read_eof', actively enters the coroutine to interrupt it.

From: Paolo Bonzini <pbonzini@redhat.com>
This property can be useful for distros to set up known-good ROM sizes for
migration purposes. The VM will fail to start if the ROM is too large,
and migration compatibility will not be broken if the ROM is too small.
Note that even though romsize is a uint32_t, it has to be between 1
(because empty ROM files are not accepted, and romsize must be greater
than the file) and 2^31 (because values above are not powers of two and
are rejected).

get_image_size() returns an int64_t, which pci_add_option_rom() assigns
to an "int" without any range checking. A 32-bit BAR could be up to
2 GiB in size, so reject anything above it. In order to accomodate
a rounded-up size of 2 GiB, change pci_patch_ids's size argument
to unsigned.

BRANCH: rhel-av-8.4.0
UPSTREAM: Merged
BREW: https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=35163495
When the pcie slot is initialized, by default PCI_EXP_LNKSTA_DLLLA
(Data Link Layer Link Active) is set in PCI_EXP_LNKSTA
(Link Status) without checking if the slot is empty or not.
This is confusing for the kernel because as it sees the link is up
it tries to read the vendor ID and fails:

This is really a problem with virtio-net failover that hotplugs a VFIO
card during the boot process. The kernel can shutdown the slot while
QEMU is hotplugging it, and this likely ends by an automatic unplug of
the card. At the end of the boot sequence the card has disappeared.
To fix that, don't set the "Link Active" state in the init function, but
rely on the plug function to do it, as the mechanism has already been
introduced by 2f2b18f60bf1.
