ARM/Android Kodi fails WoL for DLNA #18856

Open gccfla opened 3 years ago

gccfla commented 3 years ago

Bug report

Describe the bug

Here is a clear and concise description of what the problem is:

On Android, "Settings>System>Power saving>Try to wakeup remote servers on access" draws a "MACdiscover failed for 192.168.1.92".

Expected Behavior

Here is a clear and concise description of what was expected to happen:

Silence? Or maybe a reassuring message saying MAC address had been ascertained?

Actual Behavior

MAC address, needed for WoL somehow fails.

Possible Fix

Way above my pay grade!

To Reproduce

Steps to reproduce the behavior:

  1. Install working MiniDLNA server with functioning WoL on Linux box and use requisite magic to tell Kodi about it.
  2. Enable "Try to wakeup remote servers on access" in Settings
  3. See the dialog, hear the bell.

Debuglog

Additional context or screenshots (if appropriate)

Here is some additional context or explanation that might help:

All my Kodi boxes are Android. Log is from MiBox4, but same problem on NVidia Shield.

Your Environment

Used Operating system:

I would hedge a bet that the default selinux policy will deny using SIOCGARP on android.

It would be interesting to know if this problem is specific to android though.

The function in question is here https://github.com/xbmc/xbmc/blob/master/xbmc/platform/android/network/NetworkAndroid.cpp#L105

I installed Kodi 18.9 from Fedora repository on my Linux box (uname -r is 5.9.9-100.fc32.x86_64). I do not get "MAC discover failed..." warning, nor is there a corresponding message in debug log. So your SIOCGARP hypothesis may be right. But ioctl() is a hornets' nest I've lately managed to avoid.

Alas, my sleeping MiniDLNA remains comatose when I try to explore its contents. My tpcdump fu is weak, but after disabling my firewall (which I really hate doing),

# tcpdump -UlnXi enp0s10 ether proto 0x0842 or udp port 9

comes up empty, telling me (I think), no WoL packets are sent.
