9pfs: prevent opening special files (CVE-2023-2861)
Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
Christian Schoenebeck [Wed, 7 Jun 2023 16:29:33 +0000 (18:29 +0200)]
9pfs: prevent opening special files (CVE-2023-2861)
The 9p protocol does not specifically define how server shall behave when
client tries to open a special file, however from security POV it does
make sense for 9p server to prohibit opening any special file on host side
in general. A sane Linux 9p client for instance would never attempt to
open a special file on host side, it would always handle those exclusively
on its guest side. A malicious client however could potentially escape
from the exported 9p tree by creating and opening a device file on host
side.
With QEMU this could only be exploited in the following unsafe setups:
- Running QEMU binary as root AND 9p 'local' fs driver AND 'passthrough'
security model.
or
- Using 9p 'proxy' fs driver (which is running its helper daemon as
root).
These setups were already discouraged for safety reasons before,
however for obvious reasons we are now tightening behaviour on this.

Let's fix this because Xen will do just that in a few commits, and because

hw/xen: Simplify emulated Xen platform init
I initially put the basic platform init (overlay pages, grant tables,
event channels) into mc->kvm_type because that was the earliest place
that could sensibly test for xen_mode==XEN_EMULATE.
The intent was to do this early enough that we could then initialise the
XenBus and other parts which would have depended on them, from a generic
location for both Xen and KVM/Xen in the PC-specific code, as seen in
https://lore.kernel.org/qemu-devel/
20230116221919.
1124201-16-dwmw2@infradead.org/
However, then the Xen on Arm patches came along, and *they* wanted to
do the XenBus init from a 'generic' Xen-specific location instead:
https://lore.kernel.org/qemu-devel/
20230210222729.957168-4-sstabellini@kernel.org/
Since there's no generic location that covers all three, I conceded to
do it for XEN_EMULATE mode in pc_basic_devices_init().
And now there's absolutely no point in having some of the platform init
done from pc_machine_kvm_type(); we can move it all up to live in a
single place in pc_basic_devices_init(). This has the added benefit that
we can drop the separate xen_evtchn_connect_gsis() function completely,
and pass just the system GSIs in directly to xen_evtchn_create().
While I'm at it, it does no harm to explicitly pass in the *number* of
said GSIs, because it does make me twitch a bit to pass an array of
impicit size. During the lifetime of the KVM/Xen patchset, that had
already changed (albeit just cosmetically) from GSI_NUM_PINS to
IOAPIC_NUM_PINS.
And document a bit better that this is for the *output* GSI for raising
CPU0's events when the per-CPU vector isn't available. The fact that
we create a whole set of them and then only waggle the one we're told
to, instead of having a single output and only *connecting* it to the
GSI that it should be connected to, is still non-intuitive for me.

Unlike other subprojects, these require an overlay directory to include

The build defines are passed through a subproject option, and posted
back to users of the library via the dependency's compile_args.
The only remaining user of GIT_SUBMODULES and GIT_SUBMODULES_ACTION

meson: subprojects: replace submodules with wrap files
Compared to submodules, .wrap files have several advantages:
* option parsing and downloading is delegated to meson
* the commit is stored in a text file instead of a magic entry in the
git tree object
* we could stop shipping external dependencies that are only used as a
fallback, but not break compilation on platforms that lack them.
For example it may make sense to download dtc at build time, controlled
by --enable-download, even when building from a tarball. Right now,
this patch does the opposite: make-release treats dtc like libvfio-user
(which is not stable API and therefore hasn't found its way into any
distros) and keycodemap (which is a copylib, for better or worse).
dependency() can fall back to a wrap automatically. However, this
is only possible for libraries that come with a .pc file, and this
is not very common for libfdt even though the upstream project in
principle provides it; it also removes the control that we provide with
--enable-fdt={system,internal}. Therefore, the logic to pick system
vs. internal libfdt is left untouched.
--enable-fdt=git is removed; it was already a synonym for
--enable-fdt=internal.

configure: remove --with-git= option
The scenario for which --with-git= was introduced was to use a SOCKS proxy
such as tsocks. However, this was back in 2017 when QEMU's submodules
used the git:// protocol, and it is not as important when using the
"smart HTTP" backend; for example, neither "meson subprojects download"
nor scripts/checkpatch.pl obey the GIT environment variable.
So remove the knob, but test for the presence of git in the configure and
git-submodule.sh scripts, and suggest using --with-git-submodules=validate
+ a manual invocation of git-submodule.sh when git does not work. Hopefully
in the future the GIT environment variable will be supported by Meson.

mkvenv: always pass locally-installed packages to pip
Let pip decide whether a new version should be installed or the current
one is okay. This ensures that the virtual environment is updated
(either upgraded or downgraded) whenever a new version of a package is
requested.
The hardest part here is figuring out if a package is installed in
the venv (which also has to be done twice to account for the presence
of either setuptools in Python <3.8, or importlib in Python >=3.8).

tests: Use separate virtual environment for avocado
This reverts commits
eea2d141179 ("Makefile: remove $(TESTS_PYTHON)",
2023-05-26) and
9c6692db550 ("tests: Use configure-provided pyvenv for
tests", 2023-05-18).
Right now, there is a conflict between wanting a ">=" constraint when
using a distro-provided package and wanting a "==" constraint when
installing Avocado from PyPI; this would provide the best of both worlds
in terms of resiliency for both distros that have required packages and
distros that don't.
The conflict is visible also for meson, where we would like to install
the latest 0.63.x version but also accept a distro 1.1.x version.
But it is worse for avocado, for two reasons:
1) we cannot use an "==" constraint to install avocado if the venv
includes a system avocado. The distro will package plugins that have
"==" constraints on the version that is included in the distro, and, using
"pip install avocado==88.1" on a venv that includes system packages will
result in this error:
ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
avocado-framework-plugin-varianter-yaml-to-mux 98.0 requires avocado-framework==98.0, but you have avocado-framework 88.1 which is incompatible.
avocado-framework-plugin-result-html 98.0 requires avocado-framework==98.0, but you have avocado-framework 88.1 which is incompatible.
make[1]: Leaving directory '/home/berrange/src/virt/qemu/build'
2) we cannot use ">=" either if the venv does _not_ include a system
avocado, because that would result in the installation of v101.0 which
is the one we've just reverted.
So the idea is to encode the dependencies as an (acceptable, locked)
tuple, like this hypothetical TOML that would be committed inside
python/ and used by mkvenv.py:
[meson]
meson = { minimum = "0.63.0", install = "0.63.3", canary = "meson" }
[docs]
# 6.0 drops support for Python 3.7
sphinx = { minimum = "1.6", install = "<6.0", canary = "sphinx-build" }
sphinx_rtd_theme = { minimum = "0.5" }
[avocado]
avocado-framework = { minimum = "88.1", install = "88.1", canary = "avocado" }
Once this is implemented, it would also be possible to install avocado in
pyvenv/ using "mkvenv.py ensure", thus using the distro package on Fedora
and CentOS Stream (the only distros where it's available). But until
this is implemented, keep avocado in a separate venv. There is still the
benefit of using a single python for meson custom_targets and for sphinx.
