From: Geert Uytterhoeven <geert+renesas@glider.be>
Date: Thu, 26 Apr 2018 11:04:38 +0100
Subject: [PATCH] device_tree: Increase FDT_MAX_SIZE to 1 MiB
It is not uncommon for a contemporary FDT to be larger than 64 KiB,
leading to failures loading the device tree from sysfs:
qemu-system-aarch64: qemu_fdt_setprop: Couldn't set ...: FDT_ERR_NOSPACE
Hence increase the limit to 1 MiB, like on PPC.
For reference, the largest arm64 DTB created from the Linux sources is
ca. 75 KiB large (100 KiB when built with symbols/fixup support).

Subject: [PATCH] ccid: Fix dwProtocols advertisement of T=0
Commit d7d218ef02d87c637d20d64da8f575d434ff6f78 attempted to change
dwProtocols to only advertise support for T=0 and not T=1. The change
was incorrect as it changed 0x00000003 to 0x00010000.
lsusb -v in a linux guest shows:
"dwProtocols 65536 (Invalid values detected)", though the
smart card could still be accessed. Windows 7 does not detect inserted
smart cards and logs the the following Error in the Event Logs:
Source: Smart Card Service
Event ID: 610
Smart Card Reader 'QEMU QEMU USB CCID 0' rejected IOCTL SET_PROTOCOL:
Incorrect function. If this error persists, your smart card or reader
may not be functioning correctly
Command Header: 03 00 00 00
Setting to 0x00000001 fixes the Windows issue.

From 99aaadeae3b73ce65b3695a9fcae454ac09db81d Mon Sep 17 00:00:00 2001

Subject: [PATCH] tcg/arm: Fix memory barrier encoding
I found with qemu 2.11.x or newer that I would get an illegal instruction
error running some Intel binaries on my ARM chromebook. On investigation,
I found it was quitting on memory barriers.
qemu instruction:
mb $0x31
was translating as:
0x604050cc: 5bf07ff5 blpl #0x600250a8
After patch it gives:
0x604050cc: f57ff05b dmb ish
In short, I found INSN_DMB_ISH (memory barrier for ARMv7) appeared to be
correct based on online docs, but due to some endian-related shenanigans it
had to be byte-swapped to suit qemu; it appears INSN_DMB_MCR (memory
barrier for ARMv6) also should be byte swapped (and this patch does so).
I have not checked for correctness of aarch64's barrier instruction.

We currently pass an integer as the subcode parameter. However,
the upper bits of the register containing the subcode need to
be 0, which is not guaranteed unless we explicitly specify the
subcode to be an unsigned long value.

Subject: [PATCH] nbd/client: fix nbd_negotiate_simple_meta_context
Initialize received variable. Otherwise, is is possible for server to
answer without any contexts, but we will set context_id to something
random (received_id is not initialized too) and return 1, which is
wrong.
To solve it, just initialize received to false. Initialize received_id
too, just to make all possible checkers happy.
Bug was introduced in 78a33ab58782efdb206de14 "nbd: BLOCK_STATUS for
standard get_block_status function: client part" with the whole

Subject: [PATCH] nbd/client: Relax handling of large NBD_CMD_BLOCK_STATUS
reply
The NBD spec is proposing a relaxation of NBD_CMD_BLOCK_STATUS
where a server may have the final extent per context give a
length beyond the original request, if it can easily prove that
subsequent bytes have the same status, on the grounds that a
client can take advantage of this information for fewer block
status requests. Since qemu 2.12 as a client always sends
NBD_CMD_FLAG_REQ_ONE, and rejects a server that sends extra
length, the upstream NBD spec will probably limit this behavior
to clients that don't request REQ_ONE semantics; but it doesn't
hurt to relax qemu to always be permissive of this server
behavior, even if it continues to use REQ_ONE.

Subject: [PATCH] qxl: fix local renderer crash
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Make sure we only ask the spice local renderer for display updates in
case we have a valid primary surface. Without that spice is confused
and throws errors in case a display update request (triggered by
screendump for example) happens in parallel to a mode switch and hits
the race window where the old primary surface is gone and the new isn't
establisted yet.

Subject: [PATCH] tcg: Limit the number of ops in a TB
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
In 6001f7729e12 we partially attempt to address the branch
displacement overflow caused by 15fa08f845.
However, gcc/testsuite/gcc.target/aarch64/advsimd-intrinsics/vqtbX.c
is a testcase that contains a TB so large as to overflow anyway.
The limit here of 8000 ops produces a maximum output TB size of
24112 bytes on a ppc64le host with that test case. This is still
much less than the maximum forward branch distance of 32764 bytes.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Commit 9b0605f9837b ("cpus: tcg: unregister thread with RCU, fix
exiting of loop on unplug") changed the exit condition of the loop in
the vCPU thread function but forgot to remove the beginning 'while (1)'
statement. The resulting code :
while (1) {
...
} while (!cpu->unplug || cpu_can_run(cpu));
is a sequence of two distinct two while() loops, the first not exiting
in case of an unplug event.
Remove the first while (1) to fix CPU unplug.

Subject: [PATCH] s390x/css: disabled subchannels cannot be status pending
The 3270 code will try to post an attention interrupt when the
3270 emulator (e.g. x3270) attaches. If the guest has not yet
enabled the subchannel for the 3270 device, we will present a spurious
cc 1 (status pending) when it uses msch on it later on, e.g. when
trying to enable the subchannel.
To fix this, just don't do anything in css_conditional_io_interrupt()
if the subchannel is not enabled. The 3270 code will work fine with
that, and the other user of this function (virtio-ccw) never
attempts to post an interrupt for a disabled device to begin with.

Subject: [PATCH] pc-bios/s390-ccw: struct tpi_info must be declared as

I've run into a compilation error today with the current version of GCC 8:
In file included from s390-ccw.h:49,
from main.c:12:
cio.h:128:1: error: alignment 1 of 'struct tpi_info' is less than 4 [-Werror=packed-not-aligned]
} __attribute__ ((packed));
^
cc1: all warnings being treated as errors
Since the struct tpi_info contains an element ("struct subchannel_id schid")
which is marked as aligned(4), we've got to mark the struct tpi_info as
aligned(4), too.

Subject: [PATCH] s390x/ccw: make sure all ccw devices are properly reset
Thomas reported that the subchannel for a 3270 device that ended up
in a broken state (status pending even though not enabled) did not
get out of that state even after a reboot (which involves a subsytem
reset). The reason for this is that the 3270 device did not define
a reset handler.
Let's fix this by introducing a base reset handler (set up for all
ccw devices) that resets the subchannel and have virtio-ccw call
its virtio-specific reset procedure in addition to that.

Subject: [PATCH] blockjob: expose error string via query
When we've reached the concluded state, we need to expose the error
state if applicable. Add the new field.
This should be sufficient for determining if a job completed
successfully or not after concluding; if we want to discriminate
based on how it failed more mechanically, we can always add an
explicit return code enumeration later.
I didn't bother to make it only show up if we are in the concluded
state; I don't think it's necessary.

Subject: [PATCH] blockjob: Fix assertion in block_job_finalize()
Every job gets a non-NULL job->txn on creation, but it doesn't
necessarily keep it until it is decommissioned: Finalising a job removes
it from its transaction. Therefore, calling 'blockdev-job-finalize' a
second time on an already concluded job causes an assertion failure.
Remove job->txn from the assertion in block_job_finalize() to fix this.
block_job_do_finalize() still has the same assertion, but if a job is
already removed from its transaction, block_job_apply_verb() will
already error out before we run into that assertion.

Subject: [PATCH] qemu-io: Use purely string blockdev options
Currently, qemu-io only uses string-valued blockdev options (as all are
converted directly from QemuOpts) -- with one exception: -U adds the
force-share option as a boolean. This in itself is already a bit
questionable, but a real issue is that it also assumes the value already
existing in the options QDict would be a boolean, which is wrong.
That has the following effect:
$ ./qemu-io -r -U --image-opts \
driver=file,filename=/dev/null,force-share=off
[1] 15200 segmentation fault (core dumped) ./qemu-io -r -U
--image-opts driver=file,filename=/dev/null,force-share=off
Since @opts is converted from QemuOpts, the value must be a string, and
we have to compare it as such. Consequently, it makes sense to also set
it as a string instead of a boolean.

Subject: [PATCH] qemu-img: Use only string options in img_open_opts
img_open_opts() takes a QemuOpts and converts them to a QDict, so all
values therein are strings. Then it may try to call qdict_get_bool(),
however, which will fail with a segmentation fault every time:
$ ./qemu-img info -U --image-opts \
driver=file,filename=/dev/null,force-share=off
[1] 27869 segmentation fault (core dumped) ./qemu-img info -U
--image-opts driver=file,filename=/dev/null,force-share=off
Fix this by using qdict_get_str() and comparing the value as a string.
Also, when adding a force-share value to the QDict, add it as a string
so it fits the rest of the dict.

"Some AMD processors only support a non-architectural means of enabling

this to a guest, an architectural definition has been created through a new
CPUID bit, 0x80000008_EBX[25], and a new MSR, 0xc001011f. With this, a
hypervisor can virtualize the existence of this definition and provide an
architectural method for using SSBD to a guest.
Add the new CPUID feature, the new MSR and update the existing SSBD
support to use this MSR when present." (from x86/speculation: Add virtualized

Subject: [PATCH] i386: define the AMD 'virt-ssbd' CPUID feature bit
(CVE-2018-3639)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
AMD Zen expose the Intel equivalant to Speculative Store Bypass Disable
via the 0x80000008_EBX[25] CPUID feature bit.
This needs to be exposed to guest OS to allow them to protect
against CVE-2018-3639.

-Locking and thread synchronisation
-----------------------------------
-
-Previously the synchronisation of the main thread and the vCPU thread
-was ensured by the holding of the BQL. However the trend has been to
-reduce the time the BQL was held across the system including under TCG
-system emulation. As it is important that batches of events are kept
-in sequence (e.g. expiring timers and checkpoints in the main thread
-while instruction checkpoints are written by the vCPU thread) we need
-another lock to keep things in lock-step. This role is now handled by
-the replay_mutex_lock. It used to be held only for each event being
-written but now it is held for a whole execution period. This results
-in a deterministic ping-pong between the two main threads.
-
-As the BQL is now a finer grained lock than the replay_lock it is almost
-certainly a bug, and a source of deadlocks, to take the
-replay_mutex_lock while the BQL is held. This is enforced by an assert.
-While the unlocks are usually in the reverse order, this is not
-necessary; you can drop the replay_lock while holding the BQL, without
-doing a more complicated unlock_iothread/replay_unlock/lock_iothread
-sequence.

- Spectre v4 vulnerability mitigation support for KVM guests.
High level description of vulnerability: Systems with microprocessors
utilizing speculative execution and speculative execution of memory
reads before the addresses of all prior memory writes are known may
allow unauthorized disclosure of information to an attacker with
local user access via a side-channel analysis.
This change permits the new x86 cpu feature flag named "ssbd" to be
presented to the guest, given that the host has this feature, and
KVM exposes it to the guest as well.
For this feature to be enabled, via adding it to the qemu commandline
(eg: -cpu <model>,+spec-ctrl,+ssbd), so the guest OS can take advantage
of the feature, spec-ctrl and ssbd support is also required in the host.
Another new x86 cpu feature flag named "virt-ssbd" is also added to
handle this vulnerability for AMD processors.

- Replay code introduced an issue for AHCI emulation, where on Windows 10
I/O would stop randomly, and Windows would then reset the AHCI device.
The issue is not yet fully identified, but reverting some of those
changes is at least for now a workaround. (bsc#1094406)

- Spectre v4 vulnerability mitigation support for KVM guests.
High level description of vulnerability: Systems with microprocessors
utilizing speculative execution and speculative execution of memory
reads before the addresses of all prior memory writes are known may
allow unauthorized disclosure of information to an attacker with
local user access via a side-channel analysis.
This change permits the new x86 cpu feature flag named "ssbd" to be
presented to the guest, given that the host has this feature, and
KVM exposes it to the guest as well.
For this feature to be enabled, via adding it to the qemu commandline
(eg: -cpu <model>,+spec-ctrl,+ssbd), so the guest OS can take advantage
of the feature, spec-ctrl and ssbd support is also required in the host.
Another new x86 cpu feature flag named "virt-ssbd" is also added to
handle this vulnerability for AMD processors.
(CVE-2018-3639 bsc#1092885)

- Replay code introduced an issue for AHCI emulation, where on Windows 10
I/O would stop randomly, and Windows would then reset the AHCI device.
The issue is not yet fully identified, but reverting some of those
changes is at least for now a workaround. (bsc#1094406)
