2016-02-17Restore some old decrypt functionalityEthan Yonker1-5/+66
Some of the convoluted convert_hex_ascii_to_key code is needed to properly decrypt CM 12.1 patterns where grid size is larger than 3x3. Change-Id: I497e17980046c60d2c69ba56e4b83c8b64b0b80e
2016-02-16cryptfs: major overhaul and cleanupSultan Qasim Khan1-575/+32
- Don't upgrade HW encrypted Lollipop devices to Marshmallow crypto - Fix support for passwords and patterns with an odd number of elements - Remove unused code - Fix build warnings Change-Id: I25f015085e5c859d0353f42f6a2fbc7ccecd48ed
2016-01-25Adopted Storage supportEthan Yonker2-1/+47
-Detects, decrypts, and mounts an adopted SD card if a secondary block device is defined (usually mmcblk1) -Handles unified storage -Displays the adopted storage in MTP along with internal -Factory Reset - wiped just like a data media device, we retain the keys folder and the storage.xml during a factory reset -Backup / Restore -Disable mass storage when adopted storage is present -Read storage nickname from storage.xml and apply it to display names in the GUI -Read storage.xml and determine what storage location is in use for /sdcard and remap accordingly libgpt_twrp is source code mostly kanged from an efimanager project. It is GPL v2 or higher, so we will opt for GPL v3. Change-Id: Ieda0030bec5155ba8d2b9167dc0016cebbf39d55

2014-12-21Allow non datamedia devices to wipe encryptionEthan Yonker2-1/+2
With 5.0 L, we decrypt automatically if the default_password is used. Non datamedia devices do not get the format data button so they cannot wipe encryption off the device. This patch add a wipe encryption button where the format data button would normally be located on the Wipe page. This patch also attempts to remove / delete the dm-crypt block device before formatting. Change-Id: I100d5d154d6c49254fd48e23279df973db5f23ae

2014-12-12Fixes for compiling crypto in older treesDees Troy3-18/+3
Some of these fixes needed to be made anyway. Note that older trees will still need to have files / repos copied into them from newer trees. Namely we need: system/security/softkeymaster hardware/libhardware/include/hardware/keymaster.h Maybe others as I did not document very carefully what I was pulling in.

2014-12-04Reduce libs needed for decrypt and clean up old decypt filesEthan Yonker34-8281/+53
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
2014-11-18Tweak 5.0 L decryptEthan Yonker1-7/+7
Mount the vendor partition if it exists so we can use any proprietary files we may need. Relocate auto decrypt when default_password is in use to after all partitions are added so that we can mount the vendor partition. Change-Id: I93455a35695779f53ef57a82d3d45c7216c13639

2014-11-12Add lollipop decrypt supportEthan Yonker3-0/+3903
Kang in cryptfs.c and cryptfs.h from vold. Use TW_INCLUDE_L_CRYPTO := true to enable. Ramdisk must contain the normal fstab file in the root in the usual format of: fstab.{ro.hardware} For examble for Nexus 5: fstab.hammerhead Or on many Qualcomm devices: fstab.qcom Tested against Android 5.0 lollipop on Nexus 7 2012 grouper. Not sure if or how this will work when we are dealing with a device with a hardware keystore. Long term we need to add a GUI element to allow entering a pattern. For now you can decrypt a pattern unlock by converting the dots to numbers in the following format: 123 456 789 So an upper-case L would translate to 14789 as a password entered on the keyboard.

2014-11-03Remove dependence on build hax in makefilesMatt Mower1-2/+0
Update makefiles to no longer rely on INTERNAL_RECOVERY_FILES. Define LOCAL_ADDITIONAL_DEPENDENCIES instead. Set LOCAL_LDFLAGS to properly link recovery executable. Change-Id: I4542104c69399b5a19674b9772ab89c3709efa72
2014-09-03Build block TWRP with RECOVERY_VARIANTMatt Mower4-5/+10
Enable TWRP to reside alongside other recoveries with the naming convention: bootable/recovery(-flag). If TWRP resides at bootable/recovery and a device does not specify RECOVERY_VARIANT, then it will build like normal. If TWRP resides at bootable/recovery-twrp, then its makefiles will only be parsed if a device specifies 'RECOVERY_VARIANT := twrp'. This prevents TWRP specific makefile warnings/errors (notably, missing DEVICE_RESOLUTION) when another recovery is being built. Change-Id: I8f02fffcd79c309c7123b9428eedc69af02e126e
2014-02-26Check crypto footer before offering to decryptEthan Yonker4-2/+45
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
2013-12-19crypto: Fix crypto dependencies for ICS/Samsung methodsOliverG964-7/+14
- libmincrypt renamed to libmincrypttwrp that is an static library - libjpegtwrp does not exist - libfs_mgrtwrp is for JB decryption methods This fixes making full builds when TW_INCLUDE_CRYPTO_SAMSUNG := true and TW_INCLUDE_CRYPTO := true are set. Somehow typing make recoveryimage doesnt push the mentioned issue. Change-Id: I7cad5db4f51152a1a8209e619b188ca88d7c74d1
