Request for Inclusion of ways to load ashmem, binder, and memfd in Fedora Remix for WSL for Waydroid and Anbox Support.

Feature Request: Add ashmem, binder, and memfd Support

---

Background

---

As a paying customer of Fedora-Remix-for-WSL from the Windows Store, I appreciate the ongoing efforts to maintain and enhance this distribution. Additionally, I have a strong interest in Waydroid, which is an Android container designed for Wayland.

Issue

---

Waydroid depends on the ashmem and binder kernel modules. In the future, it will transition to using memfd. Most Linux distributions typically ship with ashmem and binder built into the kernel, but this is not the case with Microsoft’s implementation.

I have wrote a script that downloads the kernel, compiles the headers, and loads ashmem and binder. However, this setup tends to break every time Whitewater Foundry or Microsoft updates WSL.

Request

---

It would be greatly beneficial if you could consider adding support for the following:

• ashmem
• binder
• memfd (for future compatibility)

Suggestion perhaps there could be a dnf package called android support that installs these modules

Hello @progressive-galib,

Thank you for taking the time to fill the request. Nowadays, loading modules in kernel is not supported by WSL, but will be supported soon when WSL comes with kernel 6. At that time we can consider adding packages that install those modules

[progressive-galib]

do you know any timeline or something like that on when it will be added to wsl kernel ? On Thu, Oct 24, 2024 at 12:47 AM Galib Mahfuzullah < ***@***.***> wrote:

It can happen any time. Microsoft has tried to ship this kernel twice and has rolled it back because many issues. Also, users are asking insistently for it

[progressive-galib]

any update on that ?

[crramirez]

Based on this recent release: https://github.com/microsoft/WSL2-Linux-Kernel/releases/tag/linux-msft-wsl-6.6.75.1 I may guess that they are preparing a release with kernel 6 around Ms build in may.

You can follow this discussion about the module management with the new kernel: microsoft/WSL#12586

I think now they should consider this feature seriously, because due to discontinued WSA (subsystem Android), the only lightweight way to run android is Waydroid.
