Raspberry Pi - SO_RCVBUFFORCE: Operation not Permitted

[JoeIzzard]

I am using this image in a Raspberry Pi environment, and am getting the following error repeating continuously. Everything seems to be working but the log is just full of this as log level 3.

starting.
open_ep: SO_RCVBUFFORCE: Operation not permitted
cannot read additional dns hostnames from testparm
cannot read netbios aliases from testparm

thanks - I'll look into it - is it a arm64 or arm32 bit image? what kind of raspi are you using?

thanks :)

does it work other than this error? or did you experience anything strange

[MarvAmBass]

seems to be an issue with the new shipped wsdd2 daemon (the new zeroconf stuff)

https://github.com/Netgear/wsdd2/issues/26

can you try to give wsdd2 the required net_cap?

just add the following to your docker-compose.yml

    cap_add:
      - CAP_NET_ADMIN

[MarvAmBass]

if it helps I'll update the README and maybe I'll make wsdd2 optional - so that people can choose to disable this service

thanks and kind regards

I have the same problem since today, suddenly appeared.

cap_add: - CAP_NET_ADMIN
didn't need any change

use docker swarm with 4 pi's

[MarvAmBass]

problem confirmed - evaluating... (rpi4 - 64bit bullseye)

[MarvAmBass]

error was reproduced, just add the following to your docker-compose.yml to solve problem

    cap_add:
      - CAP_NET_ADMIN

I tried to disable WSD by adding
WSDD2_DISABLE: 1

but it end with repeated error in log:
runsv wsdd2: fatal: unable to start ./run: file does not exist

and samba not working

[MarvAmBass]

thanks - I'll look into it

[MarvAmBass]

@pavelriha I've just pushed a fix, can you repull and retry?

I've just pushed a fix, can you repull and retry?

wow, that was super fast :)

BTW I tried adding the CAP_NET_ADMIN but it doesnt help, I still get
open_ep: SO_RCVBUFFORCE: Operation not permitted

WSDD2_DISABLE: 1
now works better, no error in log, but the container freeze in state "starting", last log entry is
Service "SambaBackupServer" (/services/samba.service) successfully established.

any idea?

[MarvAmBass]

you're just lucky I'm online.

super strange, I tested the open_ep: SO_RCVBUFFORCE: Operation not permitted and it worked on my raspberry pi 4 without problems after I added CAP_NET_ADMIN

to be honest, wsdd2 was a feature request - I never used it and I don't know if it works - if it doesn't even work I will remove it - but right now it only looks like this small warning/error appears

but does samba work? can you connect to it?

samba_1  | >> EXTERNAL AVAHI: found external avahi, now maintaining avahi service file 'samba.service'
samba_1  | >> EXTERNAL AVAHI: internal avahi gets disabled

those are the logs if I start it locally using the default docker-compose.yml from this repo - it seems to work fine

those are my logs when I disable wsdd2 like you did - but samba is working

I will try the default compose .. I'm using the image for a few months with some user/shares config, it worked fine, but after I accidentaly pulled new version, it stoped working :(

would be fine if you could use TAGs, so we could go back to working version..
