[MIR] vulkan-tools

[Miriam España Acebal]

------ vulkan-tools ------

[Availability]

   vulkan-utils package is present since Focal, as part of vulkan-tools package: <https://launchpad.net/ ubuntu/+source/vulkan-tools> as transitional package <https://launchpad.net/ubuntu/+source/vulkan-tools/ 1.2.131.1+dfsg1-1> : amd64 arm64 armhf ppc64el riscv64 s390x.

   In this case, vulkan-tools has to be MIR (it's source for vulkan-utils).

   The package was in sync until it had to be changed to accomodate the MIR requirements (delta contains now dep8 tests, but it's going to be fordwarded to Debian). Package with test is here:
https://code.launchpad.net/~mirespace/+git/vulkan-tools (ppa:mirespace/impish-vulkan-tools-adding-dep8-tests).

[Rationale]

   This tool is included in our GKE images for Focal and the package needs to be on main for this (so, after MIR, it needs to be promoted up to (including) Focal).

 → Building: It builds ok.

    vulkan-tools package is well maintained in Debian and also in upstream.

    It uses a debian/watch file.

    Although the package scans HW (as its target functionality is to show vulkan information related to gpu) and in that sense also "deals with exotic HW", it incorporates a mocked ICD driver that we used e. g. for testing.

[Standards compliance]

  dh style simple rules, no compat file.

[Maintenance]

  Upstream is active, the package is maintained in Debian and is a simple command tool application. Once the dep8tests were fordwarded and accepted on Debian, the package can be a sync again. In the meantime, server team is going to sign up for Ubuntu.

[Background information]

  vulkaninfo outputs various types of Vulkan information such as:

  -device properties of identified GPUs

  -Vulkan extensions supported by each GPU

  -recognized layers

  -supported image formats and format properties.

  Vulkan is a next generation graphics and compute API that provides high-efficiency, cross-platform access to modern GPUs.

  vulkan source package [1] seems to be renamed to [2] (it is also not present in the removals file [3]). Upstream [4] is now Read-only, with recommendations to use the new repositories (vulkan-tools among others).

[Availability]

   vulkaninfo tool is present up to Bionic in package vulkan-utils, as part of vulkan source package: <https://launchpad.net/ubuntu/+source/vulkan> in updates pocket <https://launchpad.net/ubuntu/+source/vulkan/1.1.70+dfsg1-1ubuntu0.18.04.1> : amd64 arm64 armhf i386 ppc64el s390x

[Rationale]

   This tool is included in our GKE images for Bionic and the package needs to be on main for this reason. Because the source package changes for the needed tool to be MIR -vulkaninfo-, here is presented this MIR for vulkaninfo in Bionic and the submitted MIR for vulkan-tools is [5] for the rest of the Ubuntu series.

[Christian Ehrhardt  (paelzer)]

FYI - this is meant to be eventually promoted throughout all our releases.
Since the location changed there is also bug 1947020 for <=Bionic.
While the source changed and even more the source-name, since the rational and many other things are actually the same I'm merging them here.

[Christian Ehrhardt  (paelzer)]

@Lukas - could you in the very same context also look at src:vulkan for Bionic please?

[Lukas Märdian (slyon)]

Hi Miriam!
I checked the vulkan-tools MIR for Jammy/Impish/Hirsute/Focal, which looks rather straight forwards, but requires a few additional changes before the MIR team can give the final ACK.

Also, I checked the vulkan MIR for Bionic, that seems to be much more complicated. Please see my remarks in the next comment. I will be requesting security review for this one, too.

------ vulkan-tools ------
[Summary]
TODO: MIR team ACK, pending some requested changes (see below).

This MIR is looking pretty good overall, I do not see any big security constraints and I think we do not need a security review. But the proposed autopkgtests should be integrated and a build-time test suite needs to be added in addition to integrating the LTO workaround (or fix) into the package itself. All of those changes need to be SRUed into the stable series down to Focal/Bionic.
This does NOT need a security review
List of specific binary packages to be promoted to main: vulkan-tools (we can probably skip the transitional vulkan-utils package).

Notes:
As this MIR is to be backdated to Hirsute/Focal (and Bionic for src:vulkan) we need the proposed changes to be SRUed to those series first. (see https://wiki.ubuntu.com/StableReleaseUpdates)

Required TODOs:
* Add build-time tests that fail the build if they don't pass
* Integrate the proposed autopkgtests
* avoid the lto-disabled list (for arm64), should be fixed (or worked around) inside the package itself
* SRU those changes down to the stable series (Impish/Hirsute/Focal/Bionic)

Recommended TODOs:
* Add a team bug subscriber
* Check build warning (in Focal version): "cube.cpp:2067:38: warning: ‘void* memset(void*, int, size_t)’ clearing an object of non-trivial type"
* Try to keep vulkan-tools more up-to-date in the future

[Duplication]
* There is no other package in main providing the same functionality.

[Dependencies]
OK:
* no other Dependencies to MIR due to this (glslang-tools is only a build-dep, all others are in main already)
* No dependencies in main that are only superficially tested requiring more tests now

[Embedded sources and static linking]
OK:
* no embedded source present
* no static linking

[Security]
OK:
* history of CVEs does not look concerning (no CVEs found)
* does not run a daemon as root
* does not use webkit1,2
* does not use lib*v8 directly
* does not parse data formats
* does not open a port
* does not process arbitrary web content
* does not use centralized online accounts
* does not integrate arbitrary javascript into the desktop
* does not deal with system authentication (eg, pam), etc)

[Common blockers]
OK:
* does not FTBFS currently
* no translation present, but none needed for this case (user visible)?
* not a python/go package, no extra constraints to consider in that regard

Recommended:
* The package does not contain any autopkgtests. Those are being prepared but we want them to be inside the archive and SRUed to all relevant series (i.e. down to Focal/Bionic):
https://git.launchpad.net/~mirespace/+git/vulkan-tools/log/?h=impish-vulkan-tools-adding-dep8-tests

Problems:

------ src:vulkan (Bionic) ------
[Summary]
TODO: MIR team ACK, pending some requested changes (see below) and security review.

The legacy src:vulkan package is quite big and contains embedded sources. It is of much bigger scope than the vulkan-tools and vulkan-loader packages there were split out of it in newer series. Any required changes would need to be SRUed into Bionic first. I wonder if this is really worth the effort to get it MIRed? I'd also like to ask for a security review with special regard to the embedded sources, as those have not been covered by the newer vulkan-loader MIR (LP: #1742711).
This does need a security review, so I'll assign ubuntu-security
List of specific binary packages to be promoted to main: vulkan-utils, libvulkan1 (libvulkan-dev can be excluded)

Notes:
The src:vulkan MIR in Bionic basically combines the MIRs of src:vulkan-loader (libvulkan1) and src:vulkan-tools (vulkan-utils) that are already (being) accepted in newer series. Therefore, it is pretty similar to the "vulkan-tools" MIR above and the "vulkan-loader" MIR in LP: #1742711, but due to embedded sources it is of much bigger scope.

Required TODOs:
* get rid of the embedded sources (or take maintenance of those, in coordination with the security team)
* make use of the integrated test suite, so that it fails the build if any tests fails
* keep track of symbol names & changes in a debian/libvulkan1.symbols file

Recommended TODOs:
* Add a team bug subscriber
* add autopkgtests
* fix lintian errors
* fix some build warnings

[Duplication]
* There is no other package in main providing the same functionality.

[Dependencies]
OK:
* no other Dependencies to MIR due to this (quilt is only a build-dep)
* No dependencies in main that are only superficially tested requiring more tests now?

[Embedded sources and static linking]
OK:
* no static linking (some static linking in loader/ and external/glsl is only used for Windows builds)

Problems:
* embedded glslang, spirv-{tools,headers}, hlsl, glm and vkjson sources

[Security]
OK:
* history of CVEs does not look concerning
* does not run a daemon as root
* does not use webkit1,2
* does not use lib*v8 directly
* does not parse data formats
* does not open a port
* does not process arbitrary web content
* does not use centralized online accounts
* does not integrate arbitrary javascript into the desktop
* does not deal with system authentication (eg, pam), etc)

[Common blockers]
OK:
* does not FTBFS currently
* no translation present, but none needed for this case (user visible)?
* not a python/go package, no extra constraints to consider in that regard

Problems:
* does have a test suite, but that doesn't seem to run during build
* no autopkgtest

[Packaging red flags]
OK:
* Ubuntu does not carry a delta (but might need one to carry the proposed changes)
* d/watch is present and looks ok (if needed, e.g. non-native)
* the current release is packaged (almost, lacking 1 release behind, afterwards the package was split into vulkan-loader and vulkan-tools)
* Upstream update history is good
* Debian/Ubuntu update history is slow (but acceptable)
* promoting this does not seem to cause issues for MOTUs that so far m...

While this is for CPC, Server team members work on it. Thereby I know that while obviously we'd appreciate a faster review, this can happen past 22.04 - but not much later. Also we have to face that the >=Focal tasks still have some TODOs to even enter security review queue - therefore this can't be of "Panic we need it now priority".

The intention is to have the required TODOs resolved by ~April and to get security review completed afterwards by Mid 2022. Setting priority to Medium (can be high once required TODOs are done), and milestone to 22.04 (the latest currently existing milestone).

Also - since the current task on >=Focal is not on Lukas but on Miriam I'm assigning the task to her.

[Brian Murray (brian-murray)]

Ubuntu 21.10 (Impish Indri) has reached end of life, so this bug will not be fixed for that specific release.

[Rodrigo Figueiredo Zaiden (rodrigo-zaiden)]

I reviewed vulkan 1.1.70+dfsg1-1ubuntu0.18.04.1 as checked into bionic.
This shouldn't be considered a full audit but rather a quick gauge of
maintainability.

vulkan is an API to control GPUs with many attributes, mainly: driver loaders,
validation layers and tools. This source package existed up until bionic and
was later split in 3 other packages: vulkan-loader, vulkan-tools and
vulkan-validationlayers. The MIR is targeting vulkan-utils package that in
later releases is part of the vulkan-tools source package.

My main concern is that upstream does not maintain this code[1] anymore, it was
moved to other repos[2][3][4][5] and the code does not match, that is, the
backport is not trivial and more than that, the code has changed too much and
many fixes can't be backported as far as I could dig into.

The most concerning issues would be (the highs from Coverity, excluding
external/):
- An out-of-bounds in loader/loader.c:3403, it was fixed in vulkan-loader but
the backport is quite a big change[6], increasing the chance of regressions.

- A memory overlap issue in loader/ that still exists in the newer repos, and
I've reported to upstream to get their opinion:
https://github.com/KhronosGroup/Vulkan-Loader/issues/988

- Two use-after-free issues in layers/vk_layer_logging.h that I couldn't find
the corresponding fix in vulkan-layer new repo[4].

I understand that the loader/ and layers/, the main points of my criticism were
moved to vulkan-loader, that is not in the MIR for newer releases (it is
vulkan-tools), but for bionic I believe we can't skip checking it since we would
be promoting vulkan-utils package. So, I would suggest this MIR to be rejected.
From a security point of view, this code is not maintainable.

Security team NACK for promoting vulkan to main: the code maintainability is
not sustainable.

There has been not further update for too long, for now we consider it invalid.
Feel free to re-open if there is effort backing it up and motivation to bring it to main.
