Public bug reported:
The Debian Sid 5.0-6 qemu-kvm package can no longer get further than the
Clover bootloader whereas 5.0-6 and earlier worked fine.
So I built qemu master from github and it has the same problem, whereas
git tag v5.0.0 (or 4.2.1) does not, so something between v5.0.0 release
and the last few days has caused the problem.
Here's my qemu script, pretty standard macOS-Simple-KVM setup on a Xeon
host:
qemu-system-x86_64 \
-enable-kvm \
-m 4G \
-machine q35,accel=kvm \
-smp 4,sockets=1,cores=2,threads=2 \
-cpu

-drive id=SystemDisk,if=none,format=raw,file=/tmp/macos_catalina.img \
-device ide-hd,bus=sata.4,drive=SystemDisk \
-usb -device usb-kbd -device usb-mouse
Perhaps something has changed in Penryn support recently, as that's
required for macos?

Also on a related note, kernel 5.6/5.7 (on Debian) hard crashes the host
when I try GPU passthrough on macos, whereas Ubuntu20/Win10 work fine -
as does 5.5 kernel.

Indeed it is, but bear in mind it was QEMU 5.1 release feature freeze
this week so most developers are busy rebasing and fixing up bugs from
the resulting merge.
Given that you have already built QEMU from source, what would help
enormously is if you can do a "git bisect" between the v5.0.0 tag
(working) and your current master (not working) and provide the output
of "git bisect log" in this bug report. By identifying the individual
commit that broke your test case, it is much easier for developers to
understand the issue and propose a fix.
ATB,
Mark.

Thanks Mark, what an interesting exercise that was - and sorry, didn't
know 5.1 was due.
So the git bisect revealed this:
$ git bisect good
5d971f9e672507210e77d020d89e0e89165c8fc9 is the first bad commit
commit 5d971f9e672507210e77d020d89e0e89165c8fc9
Author: Michael S. Tsirkin <mst@redhat.com>
Date: Wed Jun 10 09:47:49 2020 -0400
memory: Revert "memory: accept mismatching sizes in memory_region_access_valid"
Memory API documentation documents valid .min_access_size and .max_access_size
fields and explains that any access outside these boundaries is blocked.
This is what devices seem to assume.
However this is not what the implementation does: it simply
ignores the boundaries unless there's an "accepts" callback.
Naturally, this breaks a bunch of devices.
Revert to the documented behaviour.
Devices that want to allow any access can just drop the valid field,
or add the impl field to have accesses converted to appropriate
length.

Woohoo! Simply reverting that one commit
5d971f9e672507210e77d020d89e0e89165c8fc9 from today's master gets me
running again.
Not sure where that leaves us though....?

that's an interesting observation. Thank you for finding this one. It'd
be much faster to find one of about 10 debian patches which affects this
but full qemu bisect works too, ofcourse.
Simon, I can't reach you by email, your mailserver apparently
malfunctioning, - I sent you instructions about how and what to do, but
all my emails returned back - connections to your mailserver times out
from a few of networks I have access to.
This commit breaking macos guest is interesting, perhaps we should try
to fix that for 5.1.. :)

Bug description:
The Debian Sid 5.0-6 qemu-kvm package can no longer get further than
the Clover bootloader whereas 5.0-6 and earlier worked fine.
So I built qemu master from github and it has the same problem,
whereas git tag v5.0.0 (or 4.2.1) does not, so something between
v5.0.0 release and the last few days has caused the problem.
Here's my qemu script, pretty standard macOS-Simple-KVM setup on a
Xeon host:
qemu-system-x86_64 \
-enable-kvm \

Perhaps something has changed in Penryn support recently, as that's
required for macos?

Also on a related note, kernel 5.6/5.7 (on Debian) hard crashes the
host when I try GPU passthrough on macos, whereas Ubuntu20/Win10 work
fine - as does 5.5 kernel.

the debian patch is:
revert-memory-accept-mismatching-sizes-in-memory_region_access_valid-
CVE-2020-13754.patch
i'm currently building a deb package without it.
mailserver has a geoip block and doesn't use ipv6, synapticconsulting at
gmail dot com should work.

yup, building debian 5.0-6 package minus that single patch gives me
working macos catalina again.
now just got to figure out why any kernel newer than 5.5 crashes the
host when using pci passthrough - i don't fancy bisecting a whole
kernel!

Thanks for the bisection, that's really helpful - that particular patch
fixes the way in which memory region access sizes are treated as valid.
The obvious device to look at here is isa-apple-smc since I suspect that
has less CI coverage.
Looking at the access sizes of all 3 MemoryRegions within
hw/misc/applesmc.c I think these would now reject all non-byte accesses
- does the following patch help at all?

No worries - I didn't spot that those memory regions were implemented as
single-byte registers which means the access size won't matter anyway.
I had a quick look at your command line again and the only other obvious
thing I spotted was that a 64-bit access to the q35 "blackhole" region
might also be affected by this change in logic. Does the diff below help
at all?

which will log any invalid accesses and see if anything appears on

Title:
Qemu after v5.0.0 breaks macos guests
Status in QEMU:
New
Bug description:
The Debian Sid 5.0-6 qemu-kvm package can no longer get further than
the Clover bootloader whereas 5.0-6 and earlier worked fine.
So I built qemu master from github and it has the same problem,
whereas git tag v5.0.0 (or 4.2.1) does not, so something between
v5.0.0 release and the last few days has caused the problem.
Here's my qemu script, pretty standard macOS-Simple-KVM setup on a
Xeon host:
qemu-system-x86_64 \
-enable-kvm \
-m 4G \
-machine q35,accel=kvm \
-smp 4,sockets=1,cores=2,threads=2 \
-cpu
Penryn,vendor=GenuineIntel,kvm=on,+sse3,+sse4.2,+aes,+xsave,+avx,+xsaveopt,+xsavec,+xgetbv1,+avx2,+bmi2,+smep,+bmi1,+fma,+movbe,+invtsc
\

-drive id=SystemDisk,if=none,format=raw,file=/tmp/macos_catalina.img \
-device ide-hd,bus=sata.4,drive=SystemDisk \
-usb -device usb-kbd -device usb-mouse
Perhaps something has changed in Penryn support recently, as that's
required for macos?
See also https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=964247
Also on a related note, kernel 5.6/5.7 (on Debian) hard crashes the
host when I try GPU passthrough on macos, whereas Ubuntu20/Win10 work
fine - as does 5.5 kernel.

Great work Simon! I'm not an ACPI expert but that certainly seems a
plausible solution - I'll have to defer the final review to someone else
though.
The quickest way to get this reviewed is to follow the procedure at
https://wiki.qemu.org/Contribute/SubmitAPatch which is basically send a
"git format-patch" email to the qemu-devel mailing list. Adding as CC
the appropriate maintainers shown by running
"./scripts/get_maintainer.pl /path/to/my.patch" as indicated in Section
2.1 "CC the relevant maintainer" will help ensure it gets the attention
of the right people.
ATB,
Mark.

I think we should add debugging patch by Mark to qemu too, — I suspect
there will be more cases like this, since this check were turned off for
a few years. Maybe not as printf's but as logging, I dunno, but the
info it collects is really a must-have.

Hi Simon,
Just in case you're not getting emails to the git@ email address on the
patch, there has been more follow up and discussion on the qemu-devel@
list:
https://lists.gnu.org/archive/html/qemu-devel/2020-07/msg04006.html
https://lists.gnu.org/archive/html/qemu-devel/2020-07/msg04621.html

ATB,
Mark.

Title:
Qemu after v5.0.0 breaks macos guests
Status in QEMU:
New
Bug description:
The Debian Sid 5.0-6 qemu-kvm package can no longer get further than
the Clover bootloader whereas 5.0-6 and earlier worked fine.
So I built qemu master from github and it has the same problem,
whereas git tag v5.0.0 (or 4.2.1) does not, so something between
v5.0.0 release and the last few days has caused the problem.
Here's my qemu script, pretty standard macOS-Simple-KVM setup on a
Xeon host:
qemu-system-x86_64 \
-enable-kvm \
-m 4G \
-machine q35,accel=kvm \
-smp 4,sockets=1,cores=2,threads=2 \
-cpu
Penryn,vendor=GenuineIntel,kvm=on,+sse3,+sse4.2,+aes,+xsave,+avx,+xsaveopt,+xsavec,+xgetbv1,+avx2,+bmi2,+smep,+bmi1,+fma,+movbe,+invtsc
\
-device
isa-applesmc,osk="ourhardworkbythesewordsguardedpleasedontsteal(c)AppleComputerInc"
\
-smbios type=2 \
-drive if=pflash,format=raw,readonly,file="/tmp/OVMF_CODE.fd" \
-drive if=pflash,format=raw,file="/tmp/macos_catalina_VARS.fd" \
-vga qxl \
-device ich9-ahci,id=sata \
-drive id=ESP,if=none,format=raw,file=/tmp/ESP.img \
-device ide-hd,bus=sata.2,drive=ESP \
-drive id=InstallMedia,format=raw,if=none,file=/tmp/BaseSystem.img \
-device ide-hd,bus=sata.3,drive=InstallMedia \
-drive id=SystemDisk,if=none,format=raw,file=/tmp/macos_catalina.img \
-device ide-hd,bus=sata.4,drive=SystemDisk \
-usb -device usb-kbd -device usb-mouse
Perhaps something has changed in Penryn support recently, as that's
required for macos?

Also on a related note, kernel 5.6/5.7 (on Debian) hard crashes the
host when I try GPU passthrough on macos, whereas Ubuntu20/Win10 work
fine - as does 5.5 kernel.

Hi Mark,
Yes I am getting the emails from qemu-devel thanks (seems pretty slow
though - the website is faster) I replied to a couple but its over my
head mostly now!
I didn't notice Michael had done a v2 patch for 5.1, that's fine with
me.
I wonder if we can get the debian 5.0 package updated with a patch, or
if we have to wait for 5.1 to be packaged with the fix already included
from upstream?
