- virtiofsd-prevent-opening-of-special-files-CVE-2020-35517.patch
qemu (1:5.2+dfsg-4) unstable; urgency=medium
[ Michael Tokarev ]
* require libfdt >= 1.5.0-2 due to #931046
* qemu-user: attempt to preserve argv[0] when run under binfmt
(Closes: #970460)
This changes the enterpreter name for all linux-user registered
binfmts, so it potentially can break stuff. The actual binary
being registered now is /usr/libexec/qemu-binfmt/foo-binfmt-P,
which is a symlink to actual /usr/lib/qemu-foo[-static].
* ignore .git-submodule-status when building source
* some security fixes from upstream:
o arm_gic-fix-interrupt-ID-in-GICD_SGIR-CVE-2021-20221.patch
Closes: CVE-2021-20221
GIC (armv7): out-of-bound heap buffer access via an interrupt ID field
o 9pfs-Fully-restart-unreclaim-loop-CVE-2021-20181.patch
Closes: CVE-2021-20181
* non-security fixes from upstream:
pc-bios-descriptors-fix-paths-in-json-files.patch - fixes wrong paths
in edk2-firmware-related json files introduced in 5.2
[ Christian Ehrhardt ]
* d/control-in: avoid version mismatch of installed binaries
(Closes: #956377)
[ Dan Streetman ]
* Backport configure param --with-git-submodules and set to 'ignore'

Bug description:
qemu now breaks in Hirsute (it didn't 23h ago)
Broken:
https://launchpadlibrarian.net/524654684/buildlog_ubuntu-hirsute-amd64.qemu_1%3A5.2+dfsg-6ubuntu1_BUILDING.txt.gz
Good before:

Error:
../../disas/arm-a64.cc

../../disas/arm-a64.cc:20:1: note: ‘extern "C"’ linkage started here
20 | extern "C" {
| ^~~~~~~~~~
Also in disas/nanomips.cpp, ...
And indeed disas/arm-a64.cc has:
20 extern "C" {
21 #include "qemu/osdep.h"
22 #include "disas/dis-asm.h"
23 }
Through the chain of headers as reported above this gets to the templates
in /usr/include/c++/10/type_traits which fails due to that.
So C++ constructs within a C scope which is this bug.
Upstream qemu has not recently changed yet for this.
The code is the same since 2016 via commit e78490c44: "disas/arm-a64.cc:
Include osdep.h first" by Peter Maydell.
But what was different before to break it now?
To find that I was comparing Hirsute vs Hirsute-proposed ...
It is indeed failing in -proposed but working in hirsute-release.

With that I have a test env...
Doko asked me to test
https://launchpad.net/ubuntu/+source/gcc-10/10.2.1-19ubuntu1/+build/20995220/+files/g++-10_10.2.1-19ubuntu1_amd64.deb
That fails as well, but also good as well as bad case have 10.10.2.1-20ubuntu1
It must be something else.
The difference were ~340 packages I was upgrading them to spot what broke it.
I eventually found glib 2.66 -> 2.67 to break it.

Qemu try to fix/discussion at:
https://lists.gnu.org/archive/html/qemu-devel/2021-02/msg07294.html
This won't be the final solution, but it gets things going for the time being.
glib try to fix (also seems not to be ok for upstream, but would get
everything going for now). Thanks Laney btw:
