Move domain_deprecated into private policy This attribute is being actively removed from policy. Since attributes are not being versioned, partners must not be able to access and use this attribute. Move it from private and verify in the logs that rild and tee are not using these permissions. Bug: 38316109 Test: build and boot Marlin Test: Verify that rild and tee are not being granted any of these permissions. Change-Id: I31beeb5bdf3885195310b086c1af3432dc6a349b

Restore app_domain macro and move to private use. app_domain was split up in commit: 2e00e6373faa6271d7839d33c5b9e69d998ff020 to enable compilation by hiding type_transition rules from public policy. These rules need to be hidden from public policy because they describe how objects are labeled, of which non-platform should be unaware. Instead of cutting apart the app_domain macro, which non-platform policy may rely on for implementing new app types, move all app_domain calls to private policy. (cherry-pick of commit: 76035ea01971156895cf0d8efc1876bfa2025bd6) Bug: 33428593 Test: bullhead and sailfish both boot. sediff shows no policy change.

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

Confine all app domains, but make them permissive for now. As has already been done for untrusted_app, isolated_app, and bluetooth, make all the other domains used for app processes confined while making them permissive until sufficient testing has been done.

te_macros: introduce add_service() macro Introduce the add_service() macro which wraps up add/find permissions for the source domain with a neverallow preventing others from adding it. Only a particular domain should add a particular service. Use the add_service() macro to automatically add a neverallow that prevents other domains from adding the service. mediadrmserver was adding services labeled mediaserver_service. Drop the add permission as it should just need the find permission. Additionally, the macro adds the { add find } permission which causes some existing neverallow's to assert. Adjust those neverallow's so "self" can always find. Test: compile and run on hikey and emulator. No new denials were found, and all services, where applicable, seem to be running OK.

# Perform HwBinder IPC.
hwbinder_use(radio)
Annotate most remaining HALs with _client/_server This switches most remaining HALs to the _client/_server approach. To unblock efforts blocked on majority of HALs having to use this model, this change does not remove unnecessary rules from clients of these HALs. That work will be performed in follow-up commits. This commit only adds allow rules and thus does not break existing functionality. The HALs not yet on the _client/_server model after this commit are: * Allocator HAL, because it's non-trivial to declare all apps except isolated apps as clients of this HAL, which they are. * Boot HAL, because it's still on the non-attributized model and I'm waiting for update_engine folks to answer a couple of questions which will let me refactor the policy of this HAL.
