Seems that Android 13 doesn't allow any more access to /system/bin/ip command.
I tried to list the connected hotspot devices via ip neigh [1].
The error message is:
Cannot bind netlink socket: Permission denied
Is there any way to fix that issue in Android 13?
So far I tried it with the following terminal apps
Google has removed the possibility to bind netlink socket to retrieve arp table from targetSdkVersion 30 through SELinux policies. If you have root, you can disable SELinux policies and it will work, giving the command su -c setenforce 0 when you're done with ip neigh command, I suggest you to enforce SELinux policies again with command su -c setenforce 1
Without using bind function, I've made a library that does a workaround that consist in sending via netlink socket a type message not listed (30) and then I've used the socket receive to see which data system returns to that socket. From that, I've noticed that the received data was the arp table.

targetSdk setted to 32 otherwise it works.

ipcommand without flags return anything? (the screenshot shows a typoneith, which would showObject "neith" is unknown, try "ip help"on Android 12)ipreturns, that it is not installed, and I can do that viaiproute2ortermux-toolspackage. I'll try that now...
