StubVolumes are managed from outside Android (e.g. from Chrome OS). So,
their disk recreation on vold reset events should also be handled from
outside by 1) listening to reset events, and 2) calling
createStubVolume() for existing StubVolumes on reset events.

Test: 1) vold does not crash, and 2) existing volumes are successfully

FUSE BPF aims at achieving comparable performance to bind-mounts, with
the flexibility of FUSE.
Disable data and obb bind-mounts in favor of the FUSE filesystem if the
system implements the feature.

This allows for easier bumping of the KeyMint/Keystore2 version level.
At the moment this change should have no effect: the same dependency
is used, just reached via a default rather than explicitly.
However, when the Keystore2 version increases in the near future, using
this default should mean that no change is needed here: the default
definition will change to -V2 and this will be referenced here.

IVold.MOUNT_FLAG_VISIBLE is split into MOUNT_FLAG_VISIBLE_FOR_READ and
MOUNT_FLAG_VISIBLE_FOR_WRITE.
Accordingly, VolumeBase::MountFlags::kVisible is split into
kVisibleForRead and kVisibleForWrite.

This has to be allowed as a workaround until there is a way for
userspace to check the maximum DUN size directly.

Now that FDE is no longer supported, the "defaultcrypto" and "encrypt"
events are never triggered. Therefore, the actions in vdc.rc aren't
needed anymore.

Since Android 10, new devices have been required to use FBE instead of
FDE. Therefore, the FDE code is no longer needed.
Remove most of cryptfs.cpp. A few parts of it need to be kept in order
to support the dm-crypt method of adoptable storage encryption.
Keep the FDE-specific binder methods stubbed out for now until their
callers can be removed.

This is needed to debug vold mounting errors before adb is up. It also
helps diagnose failures on devices that store dmesg persistently.
Tested by adding an error log with serial attached.

This patch adds more error logging to mountFstab. In a few cases, the
were error paths with no existing error logs. In other cases, the log
messages are there to help understand error flow in logs (for example
when a function with lots of error paths returns false).

Default buffer size of 4 pages causes many missed log records
because of ring buffer overflows. This change adds a dynamic
sizing, up to 32 pages, that has shown to decrease dropped
records pretty much to nil
Fallback code automatically decreases the buffer size in case
of kernel memory fragmentation - some logs are still much
better than no logs at all

Test: manual, adb install <Apk>; checked for fallback by
increasing max size to 1024 pages

http://aosp/1845900 creates the directory with the wrong permission
and context. And when we attempt to fix it in http://aosp/1860276, the
device would fail to boot if the device is already on the bad build.
As a temporarily fix, already delete that checkin directory in vold. And
we can revert the deletion when the droidfood daily polulation gets out
of the bad state.
Bug: 203742483
Test: Update from TP1A.211016.001 and make sure the boot doesn't fail

Gmscore runs in cache group, so set the own:group of the checkin
directory to system:cache to align with other use cases. Because we
want proper user separation when accessing the dir, also provide
user id to set the correct selinux mls_level.
Bug: 197636740
Test: check selinux label, make sure checkin can access the directory.

- Original code of re-opening /proc/self/fd/fd does not work
due to selinux violation.
- fd (=pipe) passed over binder should be used as it is.
