      cryptfs: Remove dm-crypt device on failed table load · 50730033
      nkk71 authored
       * The dm-crypt device needs to be removed from
         the device-mapper driver list otherwise it will
         remain busy and cannot be used later on by
         other processes (eg vold_decrypt) or for further
         testing/debugging in recovery.

      crypto: Use system's vold for decryption · 71c6c50d
      nkk71 authored
        If TWRP crypto fails to decrypt partition, mount the system
        partition and use system's own vold to attempt decryption.
        This provides a fallback for proprietary OEM encryption as well as
        encryption methods which TWRP hasn't been updated for.
        Requirements in device tree:
        * fstab.{ro.hardware} in device/recovery/root
          The fstab does not need to be complete, but it does need the
          data partition and the encryption entries.
        * 'TW_CRYPTO_USE_SYSTEM_VOLD := true' in BoardConfig
        * 'TW_CRYPTO_USE_SYSTEM_VOLD := <list of services>'
        * Setting the flag to 'true' will just use system's vdc+vold
        * Setting the flag with additional services, will also start them
          prior to attempting vdc+vold decryption, eg: for qualcomm based
          devices you usually need 'TW_CRYPTO_USE_SYSTEM_VOLD := qseecomd'
        * For each service listed an additional import will be automatically
          added to the vold_decrypt.rc file in the form of
          You will need to add any not already existing .rc files in
          your device/recovery/root folder.
        * The service names specified in the vold_decrypt.{service}.rc files
          have to be named 'sys_{service}'
          eg: 'service sys_qseecomd /system/bin/qseecomd'
        * Any service already existing in TWRP as {service} or sbin{service} will
          be stopped and restarted as needed.
        * You can override the default init.recovery.vold_decrypt.rc file(s)
          by placing same named ones in your device/recovery/root folder.
          If you do, you'll need to manually add the needed imports.
        * If /vendor and /firmware folders are temporarily moved and symlinked
          to the folders and files in the system partition, the properties
          'vold_decrypt.symlinked_vendor' and 'vold_decrypt.symlinked_firmware'
          will be set to 1.
          This allows for additional control in the .rc files for any extra
          actions (symlinks, cp files, etc) that may be needed for decryption
          by using: on property:vold_decrypt.symlinked_vendor=1 and/or
          on property:vold_decrypt.symlinked_firmware=1 triggers.
        Debug mode: 'TW_CRYPTO_SYSTEM_VOLD_DEBUG := true' in BoardConfig
        * Specifying this flag, will enable strace on init and vdc, which will
          create separate log files in /tmp for every process created, allowing
          for detailed analysis of which services and files are being accessed.
        * Note that enabling strace will expose the password in the logs!!
        * You need to manually add strace to your build.
      Thanks to @Captain_Throwback for co-authoring and testing.
      Tested successfully on HTC devices:

      Fix decrypt of odd number length PIN on hardware crypto · 9f1f2f74
      Ethan Yonker authored
      I am not sure if we are really fixing anything other than we are
      allowing the decrypt process to continue. On hardware crypto the
      password never seems to match what is expected from the data in
      the footer, probably because the data is not stored in the footer
      and TZ does all the work. Still, if it works, it is hard to fault
      the patch.

      Allow non datamedia devices to wipe encryption · d79d9bce
      Ethan Yonker authored
      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.

      Some of these fixes needed to be made anyway. Note that older

      newer trees. Namely we need:
      Maybe others as I did not document very carefully what I was

      Reduce libs needed for decrypt and clean up old decypt files · 253368a0
      Ethan Yonker authored
      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:
      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

      sure if or how this will work when we are dealing with a device

      Build block TWRP with RECOVERY_VARIANT · 55c75cad
      Matt Mower authored
      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.
