vold works with two broad classes of block devices: untrusted devices
that come in from the wild, and trusted devices like PrivateVolume
which are encrypted.
When running blkid and fsck, we pick which SELinux execution domain
to use based on which class the device belongs to.

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.

Extend vold to look up and set SELinux contexts on the
device nodes it creates for extra loop devices and for volumes.
Prior to this change, these device nodes simply inherited the type
of their parent directory /dev/block, i.e. block_device, and vold
therefore required create_file perms to block_device:blk_file.
With this change we can scope vold down to accessing specific
block device types.
This depends on change Id3bea28f5958086716cd3db055bea309b3b5fa5a
to allow vold to use setfscreatecon().

We now run an sdcard fuse daemon on top of a physical SD card.
Add support for that.

When mounting an encrypted filesystem vold calls fs_mgr, which
will call e2fsck on the fielsystem if it's configured to, and
fs_mgr will attempt to log the output the kernel log. However,
if won't log anything unless the klog level is set to 6, aka INFO.

Change vold to use the unified fstab. This includes both
support for sdcards, and changes to the crypto code to work
with some changes to the fs_mgr library api.

Add support for keeping the keys in a separate file on another partition,
for devices with no space reserved for a footer after the userdata filesystem.
Add support for encrypting the volumes managed by vold, if they meet certain
criteria, namely being marked as nonremovable and encryptable in vold.fstab.
A bit of trickiness is required to keep vold happy.

* commit '08da5c1f17afefe3c9f4f4d4456c5757dede62e1':
vold: replace strsep by strtok_r
|
| | |
| |
| |
| |
| |

It permits more white spaces between words in vold.fstab.

The usb_mass_storage switch no longer exists in our 2.6.35 kernel.
Instead we will consider mass storage to be available if both USB is connected
and the USB mass storage function is enable.
