The test is not eligible for CTS. Reasons:
1. The init behavior does not directly affect app compat. App interact
with init only for the property service and that part is covered by
the Bionic test already.
2. This test doesn't run against the init binary installed on the
device. libinit where most of the init functionalities are
implemented is statically linked to this test binary. In other words,
this test is closer to a unit test for init.
3. This test is not compatible with Trunk stable where test and DUT are
built in different branches. The test depends on several (private)
libraries like libbase and libutils. Since the interfaces of the
libraries may have changed in the main branch, the test binary built
from the old test-dev branch may break.
This change does not remove the test. The test will still run as a unit
test during pre/post submit.
I didn't drop the `Cts` prefix from the name, because that requires
broader changes.

During PrepareSnapshotPartitionsForUpdate, we attempt to connect to
snapuserd with a 5s timeout, only to tell snapuserd to shutdown
immediately. If snapuserd isn't running, we will wait-out the whole 5
seconds. Change the logic to return early if socket_connect() calls
return ENOENT, indicating that snapuserd socket isn't used by any
process. This reduces allocateSpaceForPayload() time from 6s to 1s.

The android-4.14-stable and later kernels support the
FS_IOC_ADD_ENCRYPTION_KEY and FS_IOC_REMOVE_ENCRYPTION_KEY ioctls. This
has superseded the old way of adding fscrypt keys to the kernel, which
was to use the add_key() syscall to add keys to the "session" keyring.
On kernels that support the ioctls, Android doesn't use the obsolete
way. Since upgrading even just to Android 14 requires at minimum a
android-4.14-stable kernel (according to
https://source.android.com/docs/core/architecture/kernel/android-common#compatibility-matrix),
there is no need to support the obsolete way anymore.
Therefore, this commit removes the code from init that created a keyring
named "fscrypt" in the session keyring. It also removes the code that
created the session keyring itself, since the only reason that Android
even created a session keyring was just to hold the "fscrypt" keyring.
Flag: N/A for the following reasons:
- Removing obsolete code, which is fairly safe
- Very early code, so runtime flag cannot be used
- Even a build-time flag cannot be used, since init needs
recovery_available, which aconfig libraries do not support

With a regular x86 kernel we are always able to get 32
min bits for mmap randomization.
However to emulate 16KB for x86 app developers the kernel
can only provide 30 bits for the randomization due the to
larger page size (PAGE_SHIFT =+ 2).
Allow the min rand bits to be (32 - (PAGE_SHIFT - 12)) in
order to generically support larger than 4KB page sizes.
This should be a no-op change for all devices, except the
x86 16KB emulator, since they will always be able to get
32 random bits.

1, Previous implementation has the staged prop application done in
property_service, which caused a number of unnecessary changes which
including exposing apis like AddPersistentProperty. In addition, it made
the property_service logic complicated. A better design is to have the
staged value application done while reading the persistent properties
from file. This way, no change to property service. In addition, unit
test is much cleaner and efficient.
2, add a unit test to lock down the behavior. Specifically, it locks down that when a prop is staged, it should be applied the next time when the persistent prop is loaded. In addition, it should lock down that other persistent props are not overwritten.

The max_processes calculation is incorrect for KillProcessGroup because
the set of processes in cgroup.procs can differ between the multiple
reads in the implementation. Luckily the exact value isn't very
important because it's just logged. Remove max_processes from the API
and remove the warning about the new behavior in Android 11.
Note that we still always LOG(INFO) that any cgroup is being killed.

This fixes a bug introduced by I81b6bd984aad8f7ddec93ce74f4543e4f71be508
In the original CL, setting a sysprop `next_boot.<name>` and then
rebooting the device could remove all the persistent properties stored
in /data/property/persistent_properties. It happened because the
function `WritePersistentProperty` is called with a properties set which
is initialized as an empty set and then added with the properties which
had the next_boot prefix.
As a result...
Before the boot:
* persist.a = 1
* next_boot.b = 2
* next_boot.persist.c = 3
After the reboot:
* b = 2
* persist.c = 3
persist.a gets lost.
This change fixes the issue by populating properties set from the memory
and then save it to the file.
