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

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

This prevents denials from being generated by the base policy. Over time, these rules will be incrementally tightened to improve security. Change-Id: I4be1c987a5d69ac784a56d42fc2c9063c402de11
