[Qemu-devel] [PULL 01/19] scsi-disk: pass sense correctly for guest-recoverable errors

[Paolo Bonzini]

From: Shinichiro Kawasaki <shinichiro.kawasaki@wdc.com>

When an error was passed down to the guest because it was recoverable,
the sense length was not copied from the SG_IO data.  As a result,
the guest saw the CHECK CONDITION status but not the sense data.

[Qemu-devel] [PULL 02/19] scsi: explicitly list guest-recoverable sense codes

[Paolo Bonzini]

It's not really possible to fit all sense codes into errno codes,
especially in such a way that sense codes can be properly categorized as
either guest-recoverable or host-handled.  Create a new function that
checks for guest recoverable sense, then scsi_sense_buf_to_errno only
needs to be called for host handled sense codes.

[Qemu-devel] [PULL 03/19] scsi: add guest-recoverable ZBC errors

[Paolo Bonzini]

When running basic operations on zoned storage from the guest via
scsi-block, the following ASCs are reported for write or read commands
due to unexpected zone status or write pointer status:

     21h 04h: UNALIGNED WRITE COMMAND
     21h 05h: WRITE BOUNDARY VIOLATION
     21h 06h: ATTEMPT TO READ INVALID DATA
     55h 0Eh: INSUFFICIENT ZONE RESOURCES

Reporting these ASCs to the guest, the user applications can handle
them to manage zone/write pointer status, or help the user application
developers to understand the failure reason and fix bugs.

[Qemu-devel] [PULL 08/19] hw/i386: turn off vmport if CONFIG_VMPORT is disabled

[Paolo Bonzini]

From: Julio Montes <julio.montes@intel.com>

vmport device is not included when CONFIG_VMPORT is disabled, hence
QEMU fails with the following error:

`Unknown device 'vmport' for bus 'ISA': unknown.`

v2: imply VMPORT (Paolo Bonzini )

Should VMMOUSE also be implied?

[Qemu-devel] [PULL 09/19] memory: unref the memory region in simplify flatview

[Paolo Bonzini]

From: King Wang <king.wang@huawei.com>

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
-name guest=ubuntu,debug-threads=on
-machine pc,accel=kvm,usb=off,dump-guest-core=off
-cpu host
-m 16384
-realtime mlock=off
-smp 8,sockets=2,cores=4,threads=1
-object memory-backend-file,id=ram-node0,prealloc=yes,mem-path=/dev/hugepages,share=yes,size=8589934592
-numa node,nodeid=0,cpus=0-3,memdev=ram-node0
-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
-nodefaults
-rtc base=utc
-no-shutdown
-boot strict=on
-device piix3-usb-uhci,id=usb,bus=pci.0,addr=0x1.0x2
-device virtio-scsi-pci,id=scsi0,bus=pci.0,addr=0x2
-device virtio-serial-pci,id=virtio-serial0,bus=pci.0,addr=0x3
-drive file=ubuntu.qcow2,format=qcow2,if=none,id=drive-virtio-disk0,cache=none,aio=native
-device virtio-blk-pci,scsi=off,bus=pci.0,addr=0x4,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1
-chardev pty,id=charserial0
-device isa-serial,chardev=charserial0,id=serial0
-device usb-tablet,id=input0,bus=usb.0,port=1
-vnc 0.0.0.0:0
-device VGA,id=video0,vgamem_mb=16,bus=pci.0,addr=0x5
-device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x6
-msg timestamp=on

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.

[Qemu-devel] [PULL 11/19] util: merge main-loop.c and iohandler.c

[Paolo Bonzini]

main-loop.c has a dependency on iohandler.c, and everything breaks
if that dependency is instead satisfied by stubs/iohandler.c.
Just put everything in the same file to avoid strange dependencies
on the order of files in util-obj-y.

[Qemu-devel] [PULL 13/19] checkpatch: detect doubly-encoded UTF-8

[Paolo Bonzini]

Copy and pasting from Thunderbird's "view source" window results in double
encoding of multibyte UTF-8 sequences.  The appearance of those sequences is
very peculiar, so detect it and give an error despite the (low) possibility
of false positives.

As the major offender, I am also adding the same check to my applypatch-msg
and commit-msg hooks, but this will also cause patchew to croak loudly when
this mistake happens.

[Qemu-devel] [PULL 18/19] create_config: remove $(CONFIG_SOFTMMU) hack

[Paolo Bonzini]

CONFIG_TPM is defined to a rather weird $(CONFIG_SOFTMMU) so that it
expands to the right thing in hw/Makefile.objs.  This however is not
needed anymore and it has a corresponding hack in create_config
to turn it into "#define CONFIG_TPM 1".  Clean up.

[Qemu-devel] [PULL 19/19] vl: make sure char-pty message displayed by moving setbuf to the beginning

[Paolo Bonzini]

From: Wei Yang <richardw.yang@linux.intel.com>

Recently we found a behavior change after commit 6ade45f2ac93611
('char-pty: Print "char device redirected" message to stdout').

When we redirect output to a file, the message "char device redirected
to PTY_NAME (label LABEL)" would not be seen at the beginning of the
file. Instead, the message is displayed after QEMU quit. This will block
test automation.

The reason is this message is printed after we set line buffer mode. So
move this to the beginning.

Hi Paolo -- it looks like this may have broken the
travis config "--without-default-devices":

Here's a sample failing build:
https://travis-ci.org/qemu/qemu/jobs/559509325

minikconf barfs with "contradiction between clauses"

Traceback (most recent call last):
  File "/home/travis/build/qemu/qemu/scripts/minikconf.py", line 703,
in <module>
    config = data.compute_config()
  File "/home/travis/build/qemu/qemu/scripts/minikconf.py", line 253,
in compute_config
    clause.process()
  File "/home/travis/build/qemu/qemu/scripts/minikconf.py", line 188, in process
    self.dest.set_value(False, self)
  File "/home/travis/build/qemu/qemu/scripts/minikconf.py", line 118,
in set_value
    raise KconfigDataError('contradiction between clauses when setting
%s' % self)
__main__.KconfigDataError: contradiction between clauses when setting VMMOUSE


I guess this is Julio's commit 97fd1ea8c10658?

thanks

Alex Bennée already has a queued patch for this (and I did too but I
removed it in favor of his).  You can apply it directly from message-id
<20190717134335.15351-18-alex.bennee@linaro.org>.
