Description
Hi,
I have an Android 12 device with socketcan support. I wrote a basic canbus code. This code scans the canbus devices and selects one, just like in the qt sample codes. When I run the code, I get the following logs on application output screen of QT. I have root access. Dmesg also gives the same output. If I set Selinux to permissive, all canbus features work perfectly on my Android. If I set Selinux to Enforcing, my app and any qt canbus examples cant accessing canbus anymore. What should I do to pass Enforcing Selinux ?
I'am using Qt6.5.3 right now but older Qt6 versions is already had same problem. I tried 6.2, 6.4 and 6.5.
