Split system_app from system. system_app is for apps that run in the system UID, e.g. Settings. system is for the system_server. Split them into separate files and note their purpose in the comment header of each file. Change-Id: I19369abc728ba2159fd50ae6b230828857e19f10 Signed-off-by: Stephen Smalley <sds@tycho.nsa.gov>

Create attribute for moving perms out of domain Motivation: Domain is overly permissive. Start removing permissions from domain and assign them to the domain_deprecated attribute. Domain_deprecated and domain can initially be assigned to all domains. The goal is to not assign domain_deprecated to new domains and to start removing domain_deprecated where it is not required or reassigning the appropriate permissions to the inheriting domain when necessary.

app_domain(system_app)
Resolve overlapping rules between app.te and net.te. There is some overlap between socket rules in app.te and the net.te rules, but they aren't quite identical since not all app domains presently include the net_domain() macro and because the rules in app.te allow more permissions for netlink_route_socket and allow rawip_socket permissions for ping. The current app.te rules prevent one from ever creating a non-networked app domain. Resolve this overlap by: 1) Adding the missing permissions allowed by app.te to net.te for netlink_route_socket and rawip_socket. 2) Adding net_domain() calls to all existing app domains that do not already have it. 3) Deleting the redundant socket rules from app.te. Then we'll have no effective change in what is allowed for apps but allow one to define app domains in the future that are not allowed network access. Also cleanup net.te to use the create_socket_perms macro rather than * and add macros for stream socket permissions.

net_domain(system_app)
Address bug report denials. Triggering a bug report via Settings > Developer Options > Take bug report generates a number of denials. Two bugs here: 1) According to the "allowed" list in frameworks/native/cmds/servicemanager/service_manager.c , media apps, nfc, radio, and apps with system/root UIDs can register as a binder service. However, they were not placed into the binder_service domain. Fix them. 2) The bugreport mechanism queries all the services and java programs and asks them to write to a shell owned file. Grant the corresponding SELinux capability. Addresses the following denials: <5>[ 149.342181] type=1400 audit(1389419775.872:17): avc: denied { write } for pid=4023 comm="dumpsys" path="/data/data/com.android.shell/files/bugreports/bugreport-2014-01-10-21-55-46.txt.tmp" dev="mmcblk0p28" ino=82094 scontext=u:r:keystore:s0 tcontext=u:object_r:shell_data_file:s0 tclass=file <5>[ 149.371844] type=1400 audit(1389419775.902:18): avc: denied { write } for pid=4023 comm="dumpsys" path="/data/data/com.android.shell/files/bugreports/bugreport-2014-01-10-21-55-46.txt.tmp" dev="mmcblk0p28" ino=82094 scontext=u:r:healthd:s0 tcontext=u:object_r:shell_data_file:s0 tclass=file <5>[ 149.980161] type=1400 audit(1389419776.512:22): avc: denied { write } for pid=4023 comm="dumpsys" path="/data/data/com.android.shell/files/bugreports/bugreport-2014-01-10-21-55-46.txt.tmp" dev="mmcblk0p28" ino=82094 scontext=u:r:drmserver:s0 tcontext=u:object_r:shell_data_file:s0 tclass=file <5>[ 150.095066] type=1400 audit(1389419776.622:23): avc: denied { write } for pid=1514 comm="Binder_C" path="/data/data/com.android.shell/files/bugreports/bugreport-2014-01-10-21-55-46.txt.tmp" dev="mmcblk0p28" ino=82094 scontext=u:r:system_app:s0 tcontext=u:object_r:shell_data_file:s0 tclass=file <5>[ 150.096748] type=1400 audit(1389419776.632:24): avc: denied { getattr } for pid=3178 comm="Binder_3" path="/data/data/com.android.shell/files/bugreports/bugreport-2014-01-10-21-55-46.txt.tmp" dev="mmcblk0p28" ino=82094 scontext=u:r:system_app:s0 tcontext=u:object_r:shell_data_file:s0 tclass=file <5>[ 150.097090] type=1400 audit(1389419776.632:25): avc: denied { write } for pid=1514 comm="Binder_C" path="/data/data/com.android.shell/files/bugreports/bugreport-2014-01-10-21-55-46.txt.tmp" dev="mmcblk0p28" ino=82094 scontext=u:r:untrusted_app:s0 tcontext=u:object_r:shell_data_file:s0 tclass=file <5>[ 154.545583] type=1400 audit(1389419781.072:43): avc: denied { write } for pid=1423 comm="Binder_A" path="/data/data/com.android.shell/files/bugreports/bugreport-2014-01-10-21-55-46.txt.tmp" dev="mmcblk0p28" ino=82094 scontext=u:r:media_app:s0 tcontext=u:object_r:shell_data_file:s0 tclass=file <5>[ 156.000877] type=1400 audit(1389419782.532:44): avc: denied { write } for pid=1423 comm="Binder_A" path="/data/data/com.android.shell/files/bugreports/bugreport-2014-01-10-21-55-46.txt.tmp" dev="mmcblk0p28" ino=82094 scontext=u:r:radio:s0 tcontext=u:object_r:shell_data_file:s0 tclass=file <5>[ 156.022567] type=1400 audit(1389419782.552:45): avc: denied { write } for pid=1423 comm="Binder_A" path="/data/data/com.android.shell/files/bugreports/bugreport-2014-01-10-21-55-46.txt.tmp" dev="mmcblk0p28" ino=82094 scontext=u:r:radio:s0 tcontext=u:object_r:shell_data_file:s0 tclass=file <5>[ 156.043463] type=1400 audit(1389419782.572:46): avc: denied { write } for pid=1423 comm="Binder_A" path="/data/data/com.android.shell/files/bugreports/bugreport-2014-01-10-21-55-46.txt.tmp" dev="mmcblk0p28" ino=82094 scontext=u:r:nfc:s0 tcontext=u:object_r:shell_data_file:s0 tclass=file <5>[ 156.062550] type=1400 audit(1389419782.592:47): avc: denied { write } for pid=1423 comm="Binder_A" path="/data/data/com.android.shell/files/bugreports/bugreport-2014-01-10-21-55-46.txt.tmp" dev="mmcblk0p28" ino=82094 scontext=u:r:radio:s0 tcontext=u:object_r:shell_data_file:s0 tclass=file Change-Id: I365d530c38ce176617e48b620c05c4aae01324d3

Label app data directories for system UID apps with a different type. We were using system_data_file for the /data/data directories of system UID apps to match the DAC ownership of system UID shared with other system files. However, we are seeing cases where files created in these directories must be writable by other apps, and we would like to avoid allowing write to system data files outside of these directories. So introduce a separate system_app_data_file type and assign it. This should also help protect against arbitrary writes by system UID apps to other system data directories. This resolves the following denial when cropping or taking a user photo for secondary users: avc: denied { write } for path="/data/data/com.android.settings/cache/TakeEditUserPhoto2.jpg" dev="mmcblk0p28" ino=82120 scontext=u:r:untrusted_app:s0 tcontext=u:object_r:system_data_file:s0 tclass=file avc: denied { write } for path="/data/data/com.android.settings/cache/CropEditUserPhoto.jpg" dev="mmcblk0p30" ino=602905 scontext=u:r:untrusted_app:s0 tcontext=u:object_r:system_data_file:s0 tclass=file Bug: 14604553 Change-Id: Ifa10e3283b07f6bd6ecc16eceeb663edfd756cea Signed-off-by: Stephen Smalley <sds@tycho.nsa.gov>

Restore system_app access to system-owned /data directories. System UID apps want to be able to create/write to system-owned /data directories outside of their own /data/data package directory, such as /data/system/cache and /data/misc/keychain. Restore access (which was removed by Ifa10e3283b07f6bd6ecc16eceeb663edfd756cea when system_app_data_file was introduced for the /data/data package directories of system UID apps), but audit writes to system_data_file so we can look at introducing separate types for these directories in the future and ultimately remove access to the rest of the system-owned data.

set_prop(system_app, bluetooth_prop)
Replace unix_socket_connect() and explicit property sets with macro A common source of mistakes when authoring sepolicy is properly setting up property sets. This is a 3 part step of: 1. Allowing the unix domain connection to the init/property service 2. Allowing write on the property_socket file 3. Allowing the set on class property_service The macro unix_socket_connect() handled 1 and 2, but could be confusing for first time policy authors. 3 had to be explicitly added. To correct this, we introduce a new macros: set_prop(sourcedomain, targetprop) This macro handles steps 1, 2 and 3. No difference in sediff is expected.

Introduce a system_radio_prop type for sys. properties that can be set by radio or system. Introduce a dhcp_prop type for properties that can be set by dhcp or system. Drop the rild_prop vs radio_prop distinction; this was an early experiment to see if we could separate properties settable by rild versus other radio UID processes but it did not pan out.
