ad5315d442 shell: access to clear logs
Bug: 13464830

b3cb9695c4 Clarify init_shell, shell, and su domain usage.
init_shell domain is now only used for shell commands or scripts
invoked by init*.rc files, never for an interactive shell.  It
was being used for console service for a while but console service
is now assigned shell domain via seclabel in init.rc.  We may want
to reconsider the shelldomain rules for init_shell and whether they
are still appropriate.

shell domain is now used by both adb shell and console service, both
of which also run in the shell UID.

su domain is now used not only for /system/bin/su but also for
adbd and its descendants after an adb root is performed.

88ce951d89 Create new conditional userdebug_or_eng
Create a new m4 macro called userdebug_or_eng. Arguments
passed to this macro are only emitted if we're performing
a userdebug or eng build.

Merge shell.te and shell_user.te and eliminate duplicate
lines. Same for su.te and su_user.te

396015c395 Remove ping domain.
ping in Android no longer requires any additional privileges beyond
the caller.  Drop the ping domain and executable file type entirely.

Also add net_domain() to shell domain so that it can create and
use network sockets.

712ca0a4d5 Confine shell domain in -user builds only.
Confine the domain for an adb shell in -user builds only.
The shell domain in non-user builds is left permissive.
init_shell (shell spawned by init, e.g.  console service)
remains unconfined by this change.
Introduce a shelldomain attribute for rules common to all shell
domains, assign it to the shell types, and add shelldomain.te for
its rules.

d99e6d5fa1 Restrict the ability to set SELinux enforcing mode to init.
Also make su and shell permissive in non-user builds to allow
use of setenforce without violating the neverallow rule.

0130154985 Make sure exec_type is assigned to all entrypoint types.
Some file types used as domain entrypoints were missing the
exec_type attribute.  Add it and add a neverallow rule to
keep it that way.

77d4731e9d Make all domains unconfined.
This prevents denials from being generated by the base policy.
Over time, these rules will be incrementally tightened to improve
security.

81fe5f7c0f Allow all domains to read the log devices.
Read access to /dev/log/* is no longer restricted.
Filtering on reads is performed per-uid by the kernel logger driver.

c195ec3148 Split internal and external sdcards
Two new types are introduced:
sdcard_internal
sdcard_external

The existing type of sdcard, is dropped and a new attribute
sdcard_type is introduced.

The boolean app_sdcard_rw has also been changed to allow for
controlling untrusted_app domain to use the internal and external
sdcards.

Add policy for run-as program and label it in file_contexts.
Drop MLS constraints on local socket checks other than create/relabel
as this interferes with connections with services, in particular for
adb forward.
