The system property "vold.post_fs_data_done" is used by init and vold to
communicate with each other in order to set up FDE on devices that use
FDE. It needs to be gettable and settable by vold, and settable by init
and vendor_init. This was the case in Android 11 and earlier; however,
the change
https://android-review.googlesource.com/c/platform/system/sepolicy/+/1277447
("Rename exported and exported2 vold prop") broke this by giving this
property the type "vold_config_prop", which made it no longer settable
by vold.
Since none of the existing property types appear to be appropriate for
this particular property, define a new type "vold_post_fs_data_prop" and
grant the needed domains permission to get/set it.
This is one of a set of changes that is needed to get FDE working again
so that devices that launched with FDE can be upgraded to Android 12.

* changes:
Check that tracefs files are labelled as tracefs_type
Exclude vendor_modprobe from debugfs neverallow restrictions
Add neverallows for debugfs access
Add a neverallow for debugfs mounting
This reverts commit 57b64bd282.
Because it breaks the usage of boot-debug.img and
vendor_boot-debug.img.

Android R launching devices and newer must not ship with debugfs
mounted. For Android S launching devices and newer, debugfs must only be
mounted in userdebug/eng builds by init(for boot time initializations)
and dumpstate(for grabbing debug information from debugfs using the
dumpstate HAL).
This patch adds neverallow statements to prevent othe processes
being provided access to debugfs when the flag PRODUCT_SET_DEBUGFS_RESTRICTIONS
is set to true.

The type is declared in vendor policy, so the mapping should live

This patch adds ro.product.enforce_debugfs_restrictions to
property_contexts. When the property is set to true in non-user builds,
init mounts debugfs in early-init to enable boot-time debugfs
initializations and unmounts it on boot complete. Similarly dumpstate
will mount debugfs to collect information from debugfs during bugreport
collection via the dumpstate HAL and unmount debugfs once done. Doing
so will allow non-user builds to keep debugfs disabled during runtime.

NetworkStack GTS tests need get network_watchlist_service and
system_config_service to test their APIs which are used by
module. But it will block by avc denied when trying to get
these services. Thus, amend networkstack sepolicy that can get
these services correctly.
Bug: 185309847
Test: Verify GTS test can get service correctly.
