Subject: [PATCH] ARM: KVM: Check KVM_CAP_ARM_IRQ_LINE_LAYOUT_2 for smp_cpus >
256
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Host kernel within [4.18, 5.3] report an erroneous KVM_MAX_VCPUS=512
for ARM. The actual capability to instantiate more than 256 vcpus
was fixed in 5.4 with the upgrade of the KVM_IRQ_LINE ABI to support
vcpu id encoded on 12 bits instead of 8 and a redistributor consuming
a single KVM IO device instead of 2.
So let's check this capability when attempting to use more than 256
vcpus within any ARM kvm accelerated machine.

¦struct CpuTopology in MachineState at that time. See commit

Subject: [PATCH] ARM64: record vtimer tick when cpu is stopped
The vtimer kick still increases even if the vcpu is stopped when VM has
save/restore or suspend/resume operation. This will cause guest watchdog
soft-lockup if the VM has lots of memory in use.

Subject: [PATCH] arm64: Add the cpufreq device to show cpufreq info to guest
On ARM64, CPU frequency is fetched by ACPI CPPC, so we add virtual
CPPC registers and ACPI _CPC objects.
On ARM64 platform, cpu frequency is retrieved via ACPI CPPC.
A virtual cpufreq device based on ACPI CPPC is created to
present cpu frequency info to the guest.
The default frequency is set to the nominal frequency of Hi1616, which
will not support CPPC in future. On Hi1620 we are fetching the value
from Host CPPC sys file.
The default frequency is set to host cpu nominal frequency,
which is obtained from the host CPPC sysfs. Other performance
data are set to the same value, since we don't support guest
performance scaling here.
All performance data are set to the same value for we don't support
guest initiating performance scaling.
We don't emulate performance counters and simply return 1 for all
counter readings, and guest Linux should fall back to use the desired
Performance counters are also not emulated and they simply
return 1 if read, and guest should fallback to use desired
performance value as the current performance.

Subject: [PATCH 2/5] memory: unref the memory region in simplify flatview
The memory region reference is increased when insert a range
into flatview range array, then decreased by destroy flatview.
If some flat range merged by flatview_simplify, the memory region
reference can not be decreased by destroy flatview any more.
In this case, start virtual machine by the command line:
qemu-system-x86_64

-machine pc,accel=kvm,usb=off,dump-guest-core=off
-cpu host

-object memory-backend-file,id=ram-node1,prealloc=yes,mem-path=/dev/hugepages,share=yes,size=8589934592
-numa node,nodeid=1,cpus=4-7,memdev=ram-node1
-no-user-config

-device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x6

And run the script in guest OS:
while true
do
setpci -s 00:06.0 04.b=03
setpci -s 00:06.0 04.b=07
done
I found the reference of node0 HostMemoryBackendFile is a big one.

Subject: [PATCH] nbd: Fix regression with multiple meta contexts
Detected by a hang in the libnbd testsuite. If a client requests
multiple meta contexts (both base:allocation and qemu:dirty-bitmap:x)
at the same time, our attempt to silence a false-positive warning
about a potential uninitialized variable introduced botched logic: we
were short-circuiting the second context, and never sending the
NBD_REPLY_FLAG_DONE. Combining two 'if' into one 'if/else' in
bdf200a55 was wrong (I'm a bit embarrassed that such a change was my
initial suggestion after the v1 patch, then I did not review the v2
patch that actually got committed). Revert that, and instead silence
the false positive warning by replacing 'return ret' with 'return 0'
(the value it always has at that point in the code, even though it
eluded the deduction abilities of the robot that reported the false
positive).
Fixes: bdf200a5535

Subject: [PATCH 1/2] qemu-bridge-helper: restrict interface name to IFNAMSIZ
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The network interface name in Linux is defined to be of size
IFNAMSIZ(=16), including the terminating null('\0') byte.
The same is applied to interface names read from 'bridge.conf'
file to form ACL rules. If user supplied '--br=bridge' name
is not restricted to the same length, it could lead to ACL bypass
issue. Restrict interface name to IFNAMSIZ, including null byte.
This patch fixes CVE-2019-13164.

Subject: [PATCH] qxl: check release info object
When releasing spice resources in release_resource() routine,
if release info object 'ext.info' is null, it leads to null
pointer dereference. Add check to avoid it.

From 0814ef80cdf212c68b73fc1fbad4eeece3560ef9 Mon Sep 17 00:00:00 2001
From: Ying Fang <fangying1@huawei.com>

Subject: [PATCH] tests/bios-tables-test: disable this testcase
We will change ARM virt ACPI FACP and PPTT table in order to
support CPU topology information presentation. However our
change make this testcase fail since we changed the table
totally and we cannot apply patch with rpmbuild system.

Subject: [PATCH] util: add slirp_fmt() helpers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Various calls to snprintf() in libslirp assume that snprintf() returns
"only" the number of bytes written (excluding terminating NUL).
https://pubs.opengroup.org/onlinepubs/9699919799/functions/snprintf.html#tag_16_159_04
"Upon successful completion, the snprintf() function shall return the
number of bytes that would be written to s had n been sufficiently
large excluding the terminating null byte."
Introduce slirp_fmt() that handles several pathological cases the
way libslirp usually expect:
- treat error as fatal (instead of silently returning -1)
- fmt0() will always \0 end
- return the number of bytes actually written (instead of what would
have been written, which would usually result in OOB later), including
the ending \0 for fmt0()
- warn if truncation happened (instead of ignoring)
Other less common cases can still be handled with strcpy/snprintf() etc.
