* crypto: Use system's vold for decryptionnkk712017-03-065-0/+736
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 or * 'TW_CRYPTO_USE_SYSTEM_VOLD := <list of services>' Notes: * Setting the flag to 'true' will just use system's vdc+vold or * 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 init.recovery.vold_decrypt.{service}.rc 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: M8 (KK through MM), M9 (MM and N), A9 (N), 10 (N), Bolt (N), Desire 626s (MM), U Ultra (N) HTC One X9 (MTK device) And by Nikolay Jeliazkov on: Xiaomi Mi Max Change-Id: I4d22ab55baf6a2a50adde2e4c1c510c142714227
* cryptfs: Fix encryption issue due to stack corruption.nijel82017-02-191-2/+2
| | | | | | | | | | | Ioctl BLKGETSIZE expects pointer to unsigned long as argument. On 64bit target using pointer to unsigned int can cause stack corruption due to type mismatch. props to https://github.com/aopp/android_system_vold/commit/f8b8787317fc94439b63bc891eeda83f7ae2f4f6 Change-Id: I1d76c65e29479c8f0cd44b6892069b21b8249b95

* Fix decrypt of odd number length PIN on hardware cryptoEthan Yonker2016-04-281-2/+2
| | | | | | | | | | | 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. Change-Id: Ibbb286382e82523bec2064f51fa07194f84820c2

* Merge up to AOSP marshmallow-releaseEthan Yonker2015-10-094-39/+367
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to maintain compatibility with older trees, we now have minadbd.old and minui.old. I had to use a TARGET_GLOBAL_CFLAG to handle ifdef issues in minui/minui.d because healthd includes minui/minui.h and there was no other alternative to make minui.h compatible with older trees without having to modify healthd rules which is outside of TWRP. Note that the new minui does not currently have support for qcom overlay graphics. Support for this graphics mode will likely be added in a later patch set. If you are building in a 6.0 tree and have a device that needs qcom overlay graphics, be warned, as off mode charging may not work properly. A dead battery in this case could potentially brick your device if it is unable to charge as healthd handles charging duties. Update rules for building toolbox and add rules for making toybox Use permissive.sh in init.rc which will follow symlinks so we do not have to worry about what binary is supplying the setenforce functionality (toolbox, toybox, or busybox). Fix a few warnings in the main recovery binary source code. Fix a few includes that were missing that prevented compiling in 6.0 Change-Id: Ia67aa2107d260883da5e365475a19bea538e8b97

* Allow non datamedia devices to wipe encryptionEthan Yonker2014-12-212-1/+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

* Fixes for compiling crypto in older treesDees Troy2014-12-123-18/+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.

* Reduce libs needed for decrypt and clean up old decypt filesEthan Yonker2014-12-0434-8281/+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

* Add lollipop decrypt supportEthan Yonker2014-11-123-0/+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.

* Build block TWRP with RECOVERY_VARIANTMatt Mower2014-09-034-5/+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
