Permission to connect to adb was removed from untrusted_app when
the domain_deprecated attribute was removed. Add it back to support
debugging of apps. Grant to all apps as eventually
domain_deprecated will be removed from everything.

Shell user needs to be able to get current device battery_level via

Only allow shell to access the same subset of ioctl commands as
untrusted_app. This reduces the attack surface of the kernel

Access to /proc/cpuinfo was moved to domain_deprecated in commit
6e3506e1. Restore access to everyone.

Allow the shell user to stat() /dev, and vfsstat() /proc and other
labeled filesystems such as /system and /data.

Access to /proc/cpuinfo was explicitly granted to bootanim, but is no
longer required after moving it back to domain.te. Delete the redundant
entry.

Commit 4e2d2245 restored access to
/sys/devices/system/cpu for all domains, but forgot to remove the
redundant entry from bootanim.te. Cleanup the redundant entry.

Addresses the following denials:

  avc: denied { getattr } for pid=23648 comm="bionic-unit-tes" name="/" dev="proc" ino=1 scontext=u:r:shell:s0 tcontext=u:object_r:proc:s0 tclass=filesystem permissive=0

Start labeling the directory /sys/kernel/debug/tracing. The files
in this directory need to be writable to the shell user.

Remove global debugfs:file write access. This was added in the days
before we could label individual debugfs files.

Even though /dev/ion can allocate memory when opened in read-only mode,
some processes seem to unnecessarily open it in read-write mode.
This doesn't seem to be harmful, and was originally allowed in
domain_deprecated. Re-allow it.

Change-Id: Iac21a1ec4b9e769c068bfdcdeeef8a7dbc93c593

Add initial support for labeling files on /sys/kernel/debug.
The kernel support was added in https://android-review.googlesource.com/122130
but the userspace portion of the change was never completed until now.

Start labeling the file /sys/kernel/debug/tracing/trace_marker . This
is the trace_marker file, which is written to by almost all processes
in Android. Allow global write access to this file.

This change should be submitted at the same time as the system/core
commit with the same Change-Id as this patch.

- Add a new 'dumpstate' context for system properties. This context
  will be used to share state between dumpstate and Shell. For example,
  as dumpstate progresses, it will update a system property, which Shell
  will use to display the progress in the UI as a system
  notification. The user could also rename the bugreport file, in which
  case Shell would use another system property to communicate such
  change to dumpstate.
- Allow Shell to call 'ctl.bugreport stop' so the same system
  notification can be used to stop dumpstate.

The extra permissions are not needed. Delete them.

This change also adds read permission for /data/misc/zoneinfo
back to all domains. libc refernces this directory for timezone
related files, and it feels dangerous and of little value to
try to restrict access. In particular, this causes problems when the
shell user attempts to run "ls -la" to show file time stamps in
the correct timezone.

Bug: 25433265
Change-Id: I666bb460e440515151e3bf46fe2e0ac0e7c99f46

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.

1) Don't use the generic "system_data_file" for the files in /data/nativetest.
Rather, ensure it has it's own special label. This allows us to distinguish
these files from other files in SELinux policy.

2) Allow the shell user to execute files from /data/nativetest, on
userdebug or eng builds only.

3) Add a neverallow rule (compile time assertion + CTS test) that nobody
is allowed to execute these files on user builds, and only the shell user
is allowed to execute these files on userdebug/eng builds.

When the toolbox domain was introduced, we allowed all domains to exec it
to avoid breakage.  However, only domains that were previously allowed the
ability to exec /system files would have been able to do this prior to the
introduction of the toolbox domain.  Remove the rule from domain.te and add
rules to all domains that are already allowed execute_no_trans to system_file.
Requires coordination with device-specific policy changes with the same Change-Id.

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.
