The company's own ota upgrade apk, download upgrade package upgrade, prompt package compatibility verification failed;
The errors reported by different OTA apks may be different, and the log s should be the same; 9.0 has strict authority management.
avc: denied { read } for name="config.gz" dev="proc" ino=4026532109 scontext=u:r:system_app:s0 tcontext=u:object_r:config_gz:s0 tclass=file permissive=0
The permission of the message is basically the same, but the object_r:config_gz; the name of config_gz, and the type of tclass=file; scontext=u:r:system_app: where is the weight limit needed; the above is the lack of read permission.
Online viewing is in device/XXX/sepolicy/basic/non_plat/system_app.te; some permissions can be added here, but config_gz and selinuxfs above may be private and cannot be defined under device;
The correct one is system/sepolicy/private/system_app.te.
+allow system_app config_gz:file { read open };
+allow system_app selinuxfs:file { read open };
Here's the log s that reported errors
