Failed to create namespace

[intelligentpotato]

Hello.

I can not get the redroid-11-wifi image to work.

I enabled mac80211_hwsim via modprobe mac80211_hwsim

Verified that it works:

# iw dev
phy#0
        Interface wlan0
                ifindex 70
                wdev 0x1
                addr 02:00:00:00:00:00
                type managed
                txpower 20.00 dBm

Unfortunately the container gets stuck and keeps repeating the following errors in logcat:

I am launching the image using the following command:

docker run -itd --rm --privileged \
    -v ~/data0:/data \
    -p 5550:5555 \
	--name redroid11 \
    teddynight/redroid:redroid-11-wifi \
    ro.product.cpu.abilist=x86_64,arm64-v8a,x86,armeabi-v7a,armeabi \
    ro.product.cpu.abilist64=x86_64,arm64-v8a \
    ro.product.cpu.abilist32=x86,armeabi-v7a,armeabi \
    ro.dalvik.vm.isa.arm=x86 \
    ro.dalvik.vm.isa.arm64=x86_64 \
    ro.enable.native.bridge.exec=1 \
    ro.enable.native.bridge.exec64=1 \
    ro.dalvik.vm.native.bridge=libhoudini.so

The host system is Ubuntu 20.04.

Is this a known bug and what can I do to circumvent it?

Appreciate your work, your image with libhoudini saved me a lot of time!

Virtwifi subsystem (init.wifi.sh) depends on the linux network namespace isolation to work. And the container got stuck because the init failed to execute the init.wifi.sh script.
execns : Cannot open network namespace 'router' at '/proc/115/ns/net': No such file or directory means that there's something wrong with the namespace.
Make sure that the folder /data/vendor/var/run/netns/ exists.
May be you can try to manually run the command createns router, and then execns router /system/bin/ip inside the container. If the createns command works, then it will output the help msg of the ip command instead of the error msg like Unable to open file /data/vendor/var/run/netns/router.pid for namespace router1: No such file or directory.
I've met this problem before when I was trying to intergrate the subsystem into redroid, but I have forgot how I solved it.
The image runs both on my laptop (Manjaro with zen kernel) & my server (debian 11 with proxmox kernel & cgroupv1 disabled).
I have to admit that I have little knowledge about that😳, hopefully information above may be helpful to you.

In fact, the virtwifi subsystem is still buggy. The container will get stuck serval days later after it boots on my server(debian 11).
