vold: fix handling of discs with multiple majors on DirectVolume::getShareDevice()

2012-07-10T19:10:35+00:00

The method DirectVolume::getShareDevice() returns an invalid device if the partition referenced by
mPartIdx is bad. A bad partition is one where the major/minor numbers on disk don't match what is
expected.

The original major number is stored for bad partitions so the fix attempts to retrieve it and
return it if applicable.

This fix is one part of fixing ICS encryption on the i777 (and possibly other devices) where bad
partitions may exist.

DirectVolume: handle discs with multiple major numbers

2012-07-10T19:10:35+00:00

CFlag: BOARD_VOLD_DISC_HAS_MULTIPLE_MAJORS

Allows Direct Volume to handle discs with multiple major numbers.
Needed on Samsung Galaxy S II and variants.

For example:
mmcblk0p1 - 179:0
mmcblk0p2 - 179:1
mmcblk0p3 - 179:2
mmcblk0p4 - 256:0
mmcblk0p5 - 256:1

Add the ability to revert a crypto mapping when unmounting a volume

2011-09-01T01:09:35+00:00

Add the force_and_revert option to the unmount command which will force
the unmount, and revert a crypto mapping.  This is used during factory
reset so that when the internal sdcard volume is formatted, it formats
the raw device, not the encrypted mapping.

vold: allow to store key in a file on another partition

2011-06-02T23:30:14+00:00

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.
