Define a domain for the bootanim service. Leave the domain permissive initially until it gets more testing. Change-Id: I9d88d76d1ffdc79a2eff4545d37a9e615482df50 Signed-off-by: Stephen Smalley <sds@tycho.nsa.gov>

# bootanimation oneshot service
bootanim: Remove domain_deprecated Remove domain_deprecated from bootanim. This removes some unnecessarily permissive rules. As part of this, re-allow access to cgroups, proc and sysfs, removed as a result of removing domain_deprecated. Bug: 25433265 Change-Id: I58658712666c719c8f5a39fe2076c4f6d166616c

type bootanim, domain;
Introduce system_file_type system_file_type is a new attribute used to identify files which exist on the /system partition. It's useful for allow rules in init, which are based off of a blacklist of writable files. Additionally, it's useful for constructing neverallow rules to prevent regressions. Additionally, add commented out tests which enforce that all files on the /system partition have the system_file_type attribute. These tests will be uncommented in a future change after all the device-specific policies are cleaned up. Test: Device boots and no obvious problems.

Allow bootanimation to talk to hwservicemanager.

allow bootanim gpu_device:chr_file rw_file_perms;
Adds GPU sepolicy to support devices with DRM gralloc/rendering ... such as Cuttlefish (Cloud Android virtual device) which has a DRM virtio-gpu based gralloc and (sometimes) DRM virtio-gpu based rendering (when forwarding rendering commands to the host machine with Mesa3D in the guest and virglrenderer on the host). After this change is submitted, changes such as aosp/1997572 can be submitted to removed sepolicy that is currently duplicated across device/google/cuttlefish and device/linaro/dragonboard as well. Adds a sysfs_gpu type (existing replicated sysfs_gpu definitions across several devices are removed in the attached topic). The uses of `sysfs_gpu:file` comes from Mesa using libdrm's `drmGetDevices2()` which calls into `drmParsePciDeviceInfo()` to get vendor id, device id, version etc. Bug: b/161819018 Test: launch_cvd Test: launch_cvd --gpu_mode=gfxstream Change-Id: I4f7d4b0fb90bfeef72f94396ff0c5fe44d53510c Merged-In: I4f7d4b0fb90bfeef72f94396ff0c5fe44d53510c

Resync lmp-dev-plus-aosp with master A DO NOT MERGE change merged from lmp-dev to lmp-dev-plus-aosp. This is expected, but it's causing unnecessary merge conflicts when handling AOSP contributions.

# Read access to pseudo filesystems.
bootanim: allow /proc/meminfo read Allow /proc/meminfo to be read by bootanim. Not sure why it's needed, but harmless enough. Modify domain_deprecated so it doesn't use r_dir_file(). /proc/meminfo is neither a symlink nor a directory, so it doesn't make sense to create allow rules for those classes of objects. Addresses the following denial: avc: denied { read } for comm="BootAnimation" name="meminfo" dev="proc" ino=4026536593 scontext=u:r:bootanim:s0 tcontext=u:object_r:proc_meminfo:s0 tclass=file permissive=0 This denial is only showing up on flounder, flounder_lte, or dragon devices.
