Commit https://android.googlesource.com/kernel/common/+/f0ce0eee added
CAP_SYS_RESOURCE as a capability check which would allow access to
sensitive /proc/PID files. However, in an SELinux based world, allowing
this access causes CAP_SYS_RESOURCE to duplicate what CAP_SYS_PTRACE
(without :process ptrace) already provides.

Use CAP_SYS_PTRACE instead of CAP_SYS_RESOURCE.

Test: Device boots, functionality remains identical, no sys_resource
denials from system_server.

Right now, the hwcomposer hidl hal is unable to figure out where
to get the hidl mapper implementation.

It is expected that all graphics composer objects will need this
permission. The interfaces are written to work together with the
"IMapper" being the same-process ("sphal") component and the
"IComposer" interface being the binderized compoenent.

Currently, some jni libs in /vendor/lib are allowed to be executed
in java process by labelling them as same_process_hal_file. This is
wrong because those jni libs are not in fact same process HALs.

After b/37481404, those jni libs for vendor apks are embedded inside the
apk just like downloaded apks.

In order to make this possible, appdomain is allowed to execute
vendor_app_file. Note that allowing this is not a Treble violation because
vendor_app_file is Java and JNI code only. Native libraries in
/vendor/lib are still prevented from being loaded in apps except for
those are labeled as same_process_hal_file AND are loaded via the
'sphal' namespace.

Specify per-service rules for PDX transport. Now being able to
grant permissions to individual services provided by processes,
not all services of a process.

Also tighter control over which permissions are required for
client and server for individual components of IPC (endpoints,

New binder kernel changes extend the areas where
binder will set real-time scheduling priorities
on threads; to make sure the driver can correctly
determine whether a process is allowed to run
at real-time priority or not, add the capability
to the services that need it.

Test: processes run at real-time prio on incoming

When installd clears cached files on external storage, the sdcardfs
kernel filesystem needs to be kept in the loop to release any cached
dentries that it's holding onto.  (Otherwise the underlying disk
space isn't actually released.)

installd can already delete the underlying files directly (via the
media_rw_data_file rules), so this technically isn't expanding its
capabilities.
