UMS support with any volume, not only primary (1/3)

2012-11-02T16:18:48+00:00

This patch enables UMS support when any volume supports it, even when the
primary storage doesn't.

1. Vold: assign lun_numbers sequentially to the volumes being added to the
   VolumeManager.
2. Fix portions of code which assume that the device has UMS support iff the
   primary storage supports UMS.
   Instead, determine whether the device supports UMS by checking each volume.
3. Display the UMS option in Settings.apk when any volume supports it.

vold: Allow pre-configured device pairs to switch mountpoints

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

The use-case for this are devices with internal extended storage
(pseudo-SDCard emmc) and an actual microSD card reader.
In CM, we choose to use the microSD as primary storage, and leave
the internal partition mostly unused; some users usually come up with
imaginative and data-destroying ways of working around that.

This allows us to specify a pair of mountpoints which can be
switched from a user preference. For this vold.fstab:

-----
dev_mount sdcard /mnt/sdcard ...
dev_mount emmc /mnt/emmc ...
-----

We can add to build.prop:
"ro.vold.switchablepair=/mnt/sdcard,/mnt/emmc"

A persistent toggle (persist.sys.vold.switchexternal), controllable
through CMParts, can be presented to the user to allow choosing
something other than our default as primary storage.

    Use a list of possible lun paths instead of a hardcoded one.

    This will easily play nice with kernels that use gadget drivers and
    function drivers (ex: tethering support doesn't require a new vold).

    vold: cleanupAsec should only do work for EXTERNAL_STORAGE

    For devices like DINC which have both emmc and sdcard storage, only one
    of these is used for ASEC mounts.  When we're unmounting volumes, we
    need to discriminate which is which before forcing ASEC closures.

Add in ext4 support for ASEC containers

2012-04-25T21:15:15+00:00

Now forward locked applications will be in ASEC containers both internal
to the system and externally.

This change adds support for putting applications in ext4-based ASECs.

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.

Don't abort the encryption process if an internal volume is present but unmounted.

It is not a failure if the SD card is not mounted.
