### Untrusted apps.
###
### This file defines the rules for untrusted apps. An "untrusted
### app" is an APP with UID between APP_AID (10000)
### and AID_ISOLATED_START (99000).
###
### untrusted_app includes all the appdomain rules, plus the
### additional following rules:
###
type untrusted_app, domain;
permissive untrusted_app;
app_domain(untrusted_app)
net_domain(untrusted_app)
bluetooth_domain(untrusted_app)
allow untrusted_app tun_device:chr_file rw_file_perms;
# Internal SDCard rw access.
allow untrusted_app sdcard_internal:dir create_dir_perms;
allow untrusted_app sdcard_internal:file create_file_perms;
# External SDCard rw access.
allow untrusted_app sdcard_external:dir create_dir_perms;
allow untrusted_app sdcard_external:file create_file_perms;
# ASEC
allow untrusted_app asec_apk_file:dir { getattr };
allow untrusted_app asec_apk_file:file r_file_perms;
# Execute libs in asec containers.
allow untrusted_app asec_public_file:file execute;
# Create tcp/udp sockets
allow untrusted_app node_type:{ tcp_socket udp_socket } node_bind;
allow untrusted_app self:{ tcp_socket udp_socket } { create_socket_perms accept listen };
# Bind to a particular hostname/address/interface (e.g., localhost) instead of
# ANY. Normally, apps should not be listening on all interfaces.
allow untrusted_app port:{ tcp_socket udp_socket } name_bind;
# Allow the allocation and use of ptys
# Used by: https://play.google.com/store/apps/details?id=jackpal.androidterm
create_pty(untrusted_app)
# Used by Finsky / Android "Verify Apps" functionality when
# running "adb install foo.apk".
# TODO: Long term, we don't want apps probing into shell data files.
# Figure out a way to remove these rules.
# XXX Adding writing to shell_data_file to fix 10290009; this needs a real fix,
# as allowing apps to write shell data files is a significant possible security
# vuln
allow untrusted_app shell_data_file:file rw_file_perms;
allow untrusted_app shell_data_file:dir r_dir_perms;
