* Reduce libs needed for decrypt and clean up old decypt filesEthan Yonker2014-12-041-157/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | Trim cryptfs.c to remove functions that TWRP does not use for decrypt and remove the need for libfs_mgr from cryptfs.c by passing some items to cryptfs.c from the partition manager. Add support for new fstab flags: encryptable and forceencrypt=/path/to/cryptokey For example: flags=forceencrypt=/dev/block/platform/sdhci-tegra.3/by-name/MD1 Note that "footer" is the default, so you do not need to set this flag on devices that use the footer for the crypto key. Also add mounttodecrypt if you need to mount a partition during the decrypt cycle for firmware of proprietary libs. Clean up decrypt and only support one version Android 5.0 lollipop decrypt should be backwards compatible with older versions so we will only support one version, 1.3 that came with 5.0 lollipop. Remove support for Samsung TouchWiz decrypt. It does not work with the latest versions of Samsung encryption anyway and it has not been updated to work with any AOSP decryption higher than 1.1 Change-Id: I2d9c6e31df50268c91ee642c2fa090f901d9d5c9
* Check crypto footer before offering to decryptEthan Yonker2014-02-261-0/+1
| | | | | | | | | Verify that we have a valid footer with proper magic before setting things up for decryption to help prevent user confusion when dealing with data partitions that fail to mount. Also check to make sure that the block device for /data is present. Change-Id: Ie87818fe4505a8bf71df7d3934c114e7328ef3ca

* TWRP-ify AOSP codeDees_Troy2012-09-051-0/+89
Pull in most TWRP sources Stub out partition management code Make it compile -- probably will not boot Kind of a mess but have to start somewhere
