This new type will allow us to write finer-grained policy concerning asec containers. Some files of these containers need to be world readable. Change-Id: Iefee74214d664acd262edecbb4f981d633ff96ce Signed-off-by:

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

Permissive domains are only intended for development. When a device launches, we want to ensure that all permissive domains are in, at a minimum, unconfined+enforcing. Add FORCE_PERMISSIVE_TO_UNCONFINED to Android.mk. During development, this flag is false, and permissive domains are allowed. When SELinux new feature development has been frozen immediately before release, this flag will be flipped to true. Any previously permissive domains will move into unconfined+enforcing. This will ensure that all SELinux domains have at least a minimal level of protection. Unconditionally enable this flag for all user builds. Change-Id: I1632f0da0022c80170d8eb57c82499ac13fd7858

Settings > Developer Options > Profile GPU Rendering was broken, as it couldn't set a debug.* system property. In addition, system_app wasn't allowed to access init's property_service socket. Both fixed. In addition, allow system_app to write to radio_prop. Fixes the following denials: <5>[ 170.769658] type=1400 audit(1386722177.029:57): avc: denied { write } for pid=4142 comm="ndroid.settings" name="property_service" dev="tmpfs" ino=7457 scontext=u:r:system_app:s0 tcontext=u:object_r:property_socket:s0 tclass=sock_file <4>[ 170.770064] avc: denied { set } for property=debug.hwui.overdraw scontext=u:r:system_app:s0 tcontext=u:object_r:debug_prop:s0 tclass=property_service <3>[ 170.770148] init: sys_prop: permission denied uid:1000 name:debug.hwui.overdraw Bug: 12037026 Change-Id: I5e879ab339e68e9e4715266fc8a698ab6ad5756e

Allow writing to persist.sys and debug. This addresses the following denials (which are actually being enforced): <4>[ 131.700473] avc: denied { set } for property=debug.force_rtl scontext=u:r:system_server:s0 tcontext=u:object_r:shell_prop:s0 tclass=property_service <3>[ 131.700625] init: sys_prop: permission denied uid:1000 name:debug.force_rtl <4>[ 132.630062] avc: denied { set } for property=persist.sys.dalvik.vm.lib scontext=u:r:system_app:s0 tcontext=u:object_r:system_prop:s0 tclass=property_service <3>[ 132.630184] init: sys_prop: permission denied uid:1000 name:persist.sys.dalvik.vm.lib Change-Id: I5d114c0d963bf393f49f1bf13d1ed84137fbcca6

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. Change-Id: If55fe7af196636c49d10fc18be2f44669e2626c5 Signed-off-by:

This change removes the permissive line from unconfined domains. Unconfined domains can do (mostly) anything, so moving these domains into enforcing should be a no-op. The following domains were deliberately NOT changed: 1) kernel 2) init In the future, this gives us the ability to tighten up the rules in unconfined, and have those tightened rules actually work. When we're ready to tighten up the rules for these domains, we can: 1) Remove unconfined_domain and re-add the permissive line. 2) Submit the domain in permissive but NOT unconfined. 3) Remove the permissive line 4) Wait a few days and submit the no-permissive change. For instance, if we were ready to do this for adb, we'd identify a list of possible rules which allow adbd to work, re-add the permissive line, and then upload those changes to AOSP. After sufficient testing, we'd then move adb to enforcing. We'd repeat this for each domain until everything is enforcing and out of unconfined. Change-Id: If674190de3262969322fb2e93d9a0e734f8b9245

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:
