8 years agoLet's reinvent storage, yet again!
Jeff Sharkey [Wed, 24 Jun 2015 18:49:24 +0000 (11:49 -0700)]
Let's reinvent storage, yet again!

Now that we're treating storage as a runtime permission, we need to
grant read/write access without killing the app.  This is really
tricky, since we had been using GIDs for access control, and they're
set in stone once Zygote drops privileges.

The only thing left that can change dynamically is the filesystem
itself, so let's do that.  This means changing the FUSE daemon to
present itself as three different views:

/mnt/runtime_default/foo - view for apps with no access
/mnt/runtime_read/foo - view for apps with read access
/mnt/runtime_write/foo - view for apps with write access

There is still a single location for all the backing files, and
filesystem permissions are derived the same way for each view, but
the file modes are masked off differently for each mountpoint.

During Zygote fork, it wires up the appropriate storage access into
an isolated mount namespace based on the current app permissions.  When
the app is granted permissions dynamically at runtime, the system
asks vold to jump into the existing mount namespace and bind mount
the newly granted access model into place.

overall user experience.

To help set user expectations, this change offers to execute a
real-world benchmark on a storage device, returning a metric that can
be used to compare internal and external storage.  The benchmark is
generated from the strace-instrumented storage access patterns of
typical apps.

A typical device completes the benchmark in under two seconds on
internal storage, a UHS-3 SD card is even faster (!), but a very slow
Class 4 SD card takes about 30 seconds to complete, giving us a clear
signal.

The measured benchmark numbers are logged along with information
about the storage device, such as manufacturer, model, etc.  Card
serial numbers are scrubbed from output.

Support for private (adopted) volumes.

This adds support for private volumes which is just a filesystem
wrapped in a dm-crypt layer.  For now we're using the exact same
configuration as internal encryption (aes-cbc-essiv:sha256), but we
don't store any key material on the removable media.  Instead, we
store the key on internal storage, and use the GPT partition GUID
to identify which key should be used.

This means that private external storage is effectively as secure as
the internal storage of the device.  That is, if the internal storage
is encrypted, then our external storage key is also encrypted.

When partitioning disks, we now support a "private" mode which has
a PrivateVolume partition, and a currently unused 16MB metadata
partition reserved for future use.  It also supports a "mixed" mode
which creates both a PublicVolume and PrivateVolume on the same
disk.  Mixed mode is currently experimental.

For now, just add ext4 support to PrivateVolume; we'll look at f2fs
in a future change.  Add VolumeBase lifecycle for setting up crypto
mappings, and extract blkid logic into shared method.  Sprinkle some
more "static" around the cryptfs code to improve invariants.

Progress towards dynamic storage support.

Wire up new Disk and VolumeBase objects and events to start replacing
older DirectVolume code.  Use filesystem UUID as visible PublicVolume
name to be more deterministic.

When starting, create DiskSource instances based on fstab, and watch
for kernel devices to appear.  Turn matching devices into Disk
objects, scan for partitions, and create any relevant VolumeBase
objects.  Broadcast all of these events towards userspace so the
framework can decide what to mount.

Keep track of the primary VolumeBase, and update the new per-user
/storage/self/primary symlink for all started users.

Provide a reset command that framework uses to start from a known
state when runtime is restarted.  When vold is unexpectedly killed,
try recovering by unmounting everything under /mnt and /storage
before moving forward.

Remove UMS sharing support for now, since no current devices support
it; MTP is the recommended solution going forward because it offers
better multi-user support.

Switch killProcessesWithOpenFiles() to directly take signal.  Fix
one SOCK_CLOEXEC bug, but SELinux says there are more lurking.
