[Qemu-devel] [Bug 1358722] [NEW] latest acpi commits causes memory allocation fault in macosx

[Marco Minetti]

Public bug reported:

qemu release 2.1.0

Hi,
I've found a regression on MacOSX guest (10.9.4) after merging the following commits 

18045fb9f457a0f0cba2bd113c748a2dcb4ed39e pc: future-proof migration-compatibility of ACPI tables
868270f23d8db2cce83e4f082fe75e8625a5fbf9 acpi-build: tweak acpi migration limits

The migration limits make x86 chameleon bootloader generate a memory
allocation error with 0xdeadbeef address at line 899 in source file:

http://forge.voodooprojects.org/p/chameleon/source/tree/2360/branches/Bungo/i386/libsaio/acpi_patcher.c

I've not tried to recompile chameleon yet.

If you absolutely need those commits, you may be better off just
using qemu's git master branch altogether (which works fine, at
least for me). Grabbing two more or less arbitrary commits from git
and applying them on top of 2.1.0 may cause you to miss other changes
which actually enable those patches to work.

HTH,

Those commits are already included into 2.1.0 release tag. I tested
almost any commit refs from tag v2.1.0-rc3 to v2.1.0. Things get broken
with the commits above with or without following commits.

I'll wait for the next 2.1.x release on git.qemu.org to test again. I
actually prefer not to use master to build packages for my bleeding-edge
Ubuntu-based distro.

Thanks!

Hi, for what it's worth, I've observed other regressions related to the 
same commits. RedHat BZ 1128608; 
https://bugzilla.redhat.com/show_bug.cgi?id=1128608 appears to be a 
regression caused by commit 18045f.

These are definitely present in Qemu 2.1 and downstream packages based 
on 2.1.

Triaging old bug tickets... can you still reproduce this issue with the
latest version of QEMU? Or could we close this ticket nowadays?
