[Qemu-devel] [PATCH 02/11] ATAPI: STARTSTOPUNIT only eject/load media if powercondition is 0

[Kevin Wolf]

From: Ronnie Sahlberg <ronniesahlberg@gmail.com>

The START STOP UNIT command will only eject/load media if
power condition is zero.

If power condition is !0 then LOEJ and START will be ignored.

>From MMC (sbc contains similar wordings too)
  The Power Conditions field requests the block device to be placed
  in the power condition defined in
  Table 558. If this field has a value other than 0h then the Start
  and LoEj bits shall be ignored.

[Qemu-devel] [PATCH 03/11] ide: Fix error messages from static code analysis (no real error)

[Kevin Wolf]

From: Stefan Weil <sw@weilnetz.de>

Report from smatch:
hw/ide/core.c:1472 ide_exec_cmd(423) error: buffer overflow 'smart_attributes' 8 <= 29
hw/ide/core.c:1474 ide_exec_cmd(425) error: buffer overflow 'smart_attributes' 8 <= 29
hw/ide/core.c:1475 ide_exec_cmd(426) error: buffer overflow 'smart_attributes' 8 <= 29
...

The upper limit of 30 was never reached because both for loops terminated
when 'smart_attributes' reached end of list, so there was no real buffer
overflow.

Nevertheless, changing the code not only fixes the error report, but also
reduces the size of smart_attributes and simplifies the for loops.

[Qemu-devel] [PATCH 05/11] vdi: Fix warning from clang

[Kevin Wolf]

From: Stefan Weil <sw@weilnetz.de>

ccc-analyzer reports these warnings:

block/vdi.c:704:13: warning: Dereference of null pointer
            bmap[i] = VDI_UNALLOCATED;

block/vdi.c:702:13: warning: Dereference of null pointer
            bmap[i] = i;
            ^

Moving some code into the if block fixes this.
It also avoids calling function write with 0 bytes of data.

[Qemu-devel] [PATCH 07/11] ahci: properly reset PxCMD on HBA reset

[Kevin Wolf]

From: Jason Baron <jbaron@redhat.com>

While testing q35, I found that windows 7 (specifically, windows 7 ultimate
with sp1 x64), wouldn't install because it can't find the cdrom or disk drive.
The failure message is: 'A required cd/dvd device driver is missing. If you
have a driver floppy disk, CD, DVD, or USB flash drive, please insert it now.'
This can also be reproduced on piix by adding an ahci controller, and
observing that windows 7 does not see any devices behind it.

The problem is that when windows issues a HBA reset, qemu does not reset the
individual ports' PxCMD register. Windows 7 then reads back the PxCMD register
and presumably assumes that the ahci controller has already been initialized.
Windows then never sets up the PxIE register to enable interrupts, and thus it
never gets irqs back when it sends ata device inquiry commands.

This change brings qemu into ahci 1.3 specification compliance.

Section 10.4.3 HBA Reset:

"
When GHC.HR is set to '1', GHC.AE, GHC.IE, the IS register, and all port
register fields (except PxFB/PxFBU/PxCLB/PxCLBU) that are not HwInit in the
HBA's register memory space are reset.
"

I've also re-tested Fedora 16 and 17 to verify that they continue to work with
this change.

[Qemu-devel] [PATCH 10/11] Don't require encryption password for 'qemu-img info' command

[Kevin Wolf]

From: "Daniel P. Berrange" <berrange@redhat.com>

The encryption password is only required if I/O is going to be
performed on a disk image. The 'qemu-img info' command merely
reports metadata, so it should not ask for a decryption password

Are any of these appropriate for -stable?  I think some are, below:

This?  Appears to be a minor case.

Most likely this.  Jason?

This, but does anyone really use sheepdog with savevm/loadvm?
Probably a very minor issue too, not worth -stable.

And this,

And probably this too?  I'm not sure about this one.

I think all of your suggestions would be appropriate, even though most
of them fix rather theoretical cases.

Yes, this fixes a real visible bug with AHCI CD-ROMs.

Hm, that's unfortunate.  It works for me.  (At least now.)

I've pushed the tag to Github:

https://github.com/XanClic/qemu.git tags/pull-block-2019-05-07

I hope that works better.


Sorry for the inconvenience,

Yep, that worked fine: I've applied that.

Please update the changelog at https://wiki.qemu.org/ChangeLog/4.1
for any user-visible changes.

(Strace says that we seem to successfully connect to
the git.xanclic.moe server and do some talking to it,
but the first time the client issues a "fetch" command
the server never replies and the client is just blocked
in read().)

Self-NACK.  Sorry, I don't quite know how the locking fix slipped in
there, but it shouldn't be here.

 * Copy offloading for qemu-img convert (iSCSI, raw, and qcow2)

   If the underlying storage supports copy offloading, qemu-img convert will
   use it instead of performing reads and writes.  This avoids data transfers
   and thus frees up storage bandwidth for other purposes.  SCSI EXTENDED COPY
   and Linux copy_file_range(2) are used to implement this optimization.
