Merge remote-tracking branch 'remotes/philmd-gitlab/tags/python-next-20200714' into staging

Python patches for 5.1

- Reduce race conditions on QEMUMachine::shutdown()

1. Remove the "bare except" pattern in the existing shutdown code,
which can mask problems and make debugging difficult.
2. Ensure that post-shutdown cleanup is always performed, even when
graceful termination fails.
3. Unify cleanup paths such that no matter how the VM is terminated,
the same functions and steps are always taken to reset the object
state.
4. Rewrite shutdown() such that any error encountered when attempting
a graceful shutdown will be raised as an AbnormalShutdown exception.
The pythonic idiom is to allow the caller to decide if this is a
problem or not.

- Modify part of the python/qemu library to comply with:

. mypy --strict
. pylint
. flake8

- Script for the TCG Continuous Benchmarking project that uses
callgrind to dissect QEMU execution into three main phases:

. code generation
. JIT execution
. helpers execution

Merge remote-tracking branch 'remotes/philmd-gitlab/tags/sdcard-CVE-2020-13253-pull-request' into staging

Fix CVE-2020-13253

By using invalidated address, guest can do out-of-bounds accesses.
These patches fix the issue by only allowing SD card image sizes
power of 2, and not switching to SEND_DATA state when the address
is invalid (out of range).

This issue was found using QEMU fuzzing mode (using --enable-fuzzing,
see docs/devel/fuzzing.txt) and reported by Alexander Bulekov.

iotests: Specify explicit backing format where sensible

There are many existing qcow2 images that specify a backing file but
no format. This has been the source of CVEs in the past, but has
become more prominent of a problem now that libvirt has switched to
-blockdev. With older -drive, at least the probing was always done by
qemu (so the only risk of a changed format between successive boots of
a guest was if qemu was upgraded and probed differently). But with
newer -blockdev, libvirt must specify a format; if libvirt guesses raw
where the image was formatted, this results in data corruption visible
to the guest; conversely, if libvirt guesses qcow2 where qemu was
using raw, this can result in potential security holes, so modern
libvirt instead refuses to use images without explicit backing format.

The change in libvirt to reject images without explicit backing format
has pointed out that a number of tools have been far too reliant on
probing in the past. It's time to set a better example in our own
iotests of properly setting this parameter.

iotest calls to create, rebase, and convert are all impacted to some
degree. It's a bit annoying that we are inconsistent on command line
- while all of those accept -o backing_file=...,backing_fmt=..., the
shortcuts are different: create and rebase have -b and -F, while
convert has -B but no -F. (amend has no shortcuts, but the previous
patch just deprecated the use of amend to change backing chains).

Merge remote-tracking branch 'remotes/elmarco/tags/dbus-vmstate7-pull-request' into staging

Add dbus-vmstate

Hi,

With external processes or helpers participating to the VM support, it
becomes necessary to handle their migration. Various options exist to
transfer their state:
1) as the VM memory, RAM or devices (we could say that's how
vhost-user devices can be handled today, they are expected to
restore from ring state)
2) other "vmstate" (as with TPM emulator state blobs)
3) left to be handled by management layer

1) is not practical, since an external processes may legitimatelly
need arbitrary state date to back a device or a service, or may not
even have an associated device.

2) needs ad-hoc code for each helper, but is simple and working

3) is complicated for management layer, QEMU has the migration timing

The proposed "dbus-vmstate" object will connect to a given D-Bus
address, and save/load from org.qemu.VMState1 owners on migration.

Thus helpers can easily have their state migrated with QEMU, without
implementing ad-hoc support (such as done for TPM emulation)

D-Bus is ubiquitous on Linux (it is systemd IPC), and can be made to
work on various other OSes. There are several implementations and good
bindings for various languages. (the tests/dbus-vmstate-test.c is a
good example of how simple the implementation of services can be, even
in C)

dbus-vmstate is put into use by the libvirt series "[PATCH 00/23] Use
a slirp helper process".

iotests: Make 110 work with data_file

The only difference is that the json:{} filename of the image looks
different. We actually do not care about that filename in this test, we
are only interested in (1) that there is a json:{} filename, and (2)
whether the backing filename can be constructed.

So just filter out the json:{} data, thus making this test pass both
with and without data_file.

qemu-img: Saner printing of large file sizes

Disk sizes close to INT64_MAX cause overflow, for some pretty
ridiculous output:

$ ./nbdkit -U - memory size=$((2**63 - 512)) --ru

qemu-img: Saner printing of large file sizes

Disk sizes close to INT64_MAX cause overflow, for some pretty
ridiculous output:

$ ./nbdkit -U - memory size=$((2**63 - 512)) --run 'qemu-img info $nbd'
image: nbd+unix://?socket=/tmp/nbdkitHSAzNz/socket
file format: raw
virtual size: -8388607T (9223372036854775296 bytes)
disk size: unavailable

But there's no reason to have two separate implementations of integer
to human-readable abbreviation, where one has overflow and stops at
'T', while the other avoids overflow and goes all the way to 'E'. With
this patch, the output now claims 8EiB instead of -8388607T, which
really is the correct rounding of largest file size supported by qemu
(we could go 511 bytes larger if we used byte-accurate sizing instead
of rounding up to the next sector boundary, but that wouldn't change
the human-readable result).

Quite a few iotests need updates to expected output to match.

Merge remote-tracking branch 'remotes/cminyard/tags/i2c-for-release-20190228' into staging

This has been out there long enough, I need to get this in.

This was changed a little bit since my post on Feb 20 (to which
there were no comments) due to changes I had to work around:

Change b296b664abc73253 "smbus: Add a helper to generate SPD EEPROM
data" added a function to include/hw/i2c/smbus.h, which I had to move to
include/hw/smbus_eeprom.h.

There were some changes to hw/i2c/Makefile.objs that I had to fix up.

Beyond that, no changes.

Thanks,

-corey
