Steps for compile Mainline Kernel Linux using WSL2

Compile Mainline Kernel for WSL2

Steps for compile Kernel Linux 5.15.0

Actual Kernel

$ uname -a
Linux DESKTOP-ID 4.19.128-microsoft-standard #1 SMP Tue Jun 23 12:58:10 UTC 2020 x86_64 GNU/Linux

Work Dir linux

$ mkdir -p linux
$ cd linux

Install Requirements for Build

$ sudo apt install git bc build-essential flex bison libssl-dev libelf-dev dwarves

Download Linux source code

$ wget https://github.com/torvalds/linux/archive/refs/tags/v5.15.zip -O v5.15.zip

Unzip Linux sources

$ unzip v5.15.zip

Download Config WSL

$ wget https://github.com/microsoft/WSL2-Linux-Kernel/raw/linux-msft-wsl-5.10.y/Microsoft/config-wsl

Copy Config WSL as Default Config to the Linux configs

$ cp config-wsl linux-5.15/arch/x86/configs/wsl_defconfig

Generate the Configuration and Build

$ cd linux-5.15
$ make KCONFIG_CONFIG=arch/x86/configs/wsl_defconfig -j4

Copy Linux kernel to YOUR_USER

$ cp arch/x86/boot/bzImage /mnt/c/Users/YOUR_USER/

Edit the configuration for WSL

$ vim /mnt/c/Users/YOUR_USER/.wslconfig
[wsl2]
kernel=C:\\Users\\YOUR_USER\\bzImage

Shutdown WSL

$ wsl --shutdown

Check shutdown the distro WSL

$ wsl -l -v

Start distro

$ wsl -d Debian

New Kernel Linux

$ uname -a
Linux HP450-2 5.15.0-oleksis-microsoft-standard-WSL2 #1 SMP Mon Nov 29 01:14:26 EST 2021 x86_64 x86_64 x86_64 GNU/Linux

$ sudo apt install git bc build-essential flex bison libssl-dev libelf-dev

Download Linux source code

$ wget https://github.com/torvalds/linux/archive/v5.11.zip -O v5.11.zip

Prepare the directory as Case Sensitive.

> $linuxSrc =  "linux-5.11"
> $net_netfilter = "$linuxSrc\net\netfilter"
> $uapi_netfilter = "$linuxSrc\include\uapi\linux\netfilter"
> $uapi_netfilter_ipv4 = "$linuxSrc\include\uapi\linux\netfilter_ipv4"
> $uapi_netfilter_ipv6 = "$linuxSrc\include\uapi\linux\netfilter_ipv6"
> $subfolders = @("$linuxSrc", "$linuxSrc\net", "$net_netfilter", "$linuxSrc\include", "$linuxSrc\include\uapi", "$linuxSrc\include\uapi\linux", "$uapi_netfilter", "$uapi_netfilter_ipv4", "$uapi_netfilter_ipv6")
> # Create sub-folders
> $subfolders | % {New-Item -Path ".\$_" -ItemType Dir}

Set Case Sensitive. Run as Administrator!

> @($net_netfilter, $uapi_netfilter, $uapi_netfilter_ipv4, $uapi_netfilter_ipv6) | % {fsutil.exe file setCaseSensitiveInfo "$_" enable}

Check Case Sensitive. Run as Administrator! (Optional)

> fsutil.exe file queryCaseSensitiveInfo $net_netfilter
El atributo que distingue mayúsculas de minúsculas del directorio .\linux-5.11\net\netfilter está habilitado.

Unzip Linux sources

$ unzip v5.11.zip

Download Config WSL

$ wget https://raw.githubusercontent.com/microsoft/WSL2-Linux-Kernel/linux-msft-wsl-4.19.y/Microsoft/config-wsl

Copy Config WSL as Default Config to the Linux configs

$ cp config-wsl linux-5.11/arch/x86/configs/wsl_defconfig

Generate the Configuration and Build

$ cd linux-5.11
$ make KCONFIG_CONFIG=arch/x86/configs/wsl_defconfig -j2

Copy Linux kernel to YOUR_USER

$ cp vmlinux /mnt/c/Users/YOUR_USER/

Edit the configuration for WSL

$ vim /mnt/c/Users/YOUR_USER/.wslconfig
[wsl2]
kernel=C:\\Users\\YOUR_USER\\vmlinux

Shutdown WSL

$ wsl --shutdown

Check shutdown the distro WSL

$ wsl -l -v

Start distro

$ wsl -d Debian

New Kernel Linux

$ uname -a
Linux DESKTOP-ID 5.11.0-oleksis #1 SMP Fri Feb 26 19:48:22 CST 2021 x86_64 GNU/Linux

Extras

Mount externals disk drivers. Run as Administrator!

wmic diskdrive list brief
wsl --mount \\.\PHYSICALDRIVE1 --bare
