### Neverallow rules
###
### logd should NEVER do any of this
# Block device access.
neverallow logd dev_type:blk_file { read write };
# ptrace any other app
neverallow logd domain:process ptrace;
# Write to /system.
neverallow logd system_file:dir_file_class_set write;
# Write to files in /data/data or system files on /data
neverallow logd { app_data_file system_data_file }:dir_file_class_set write;
