bigbiff 998f839e82 super processing: use logical flag to denote super status
To support all partitions that are on the super partition
we now parse for the logical flag in fstab to denote super
status.

- Remove guards for the first character being '/'.
- Skip commented lines in fstab
- Build Backup_Display_Name from partitions in super.
The first four lines that are in fstab will be
displayed.

bigbiff a957f078be FsCrypt update: support fscrypt policies v1 and v2
This patchset introduces support decryption for Android 11.

In this update we deprecate ext4crypt. To specify the
policy version to use, use TW_USE_FSCRYPT_POLICY := 1 or
TW_USE_FSCRYPT_POLICY := 2. By default policy version will
be set to 2 if this variable is omitted.

bigbiff 1f9e4847ce twrpinstall: create library for twrpinstall
This library will need to mirror AOSP for any changes to installing
packages. The library has been separated out in order to make importing
updates from AOSP into the TWRP project.

twinstall.cpp has been removed from the recovery binary and added to
this library. It has been refactored for libziparchive.

Sideload has been reworked to use the newer methods from AOSP on
flashing packages through adb sideload.

We are also removing old libraries for adb and verifier.

Lastly before flashing a zip or image, we want to unlock block devices
for writing so that when an OTA is flashed to the inactive slot,
the flash will succeed.

a function and call it in cases where the default password
is being used and in cases where it isn't. This will ensure that
an unencrypted device isn't set as encrypted by mistake.

* Since some devices are unable to decrypt after processing of the fstab,
   because of the partition details updation, and after intro of dynamic partitioning
   here decryption process was going on after complete processing of the dynamic volumes.

 * This patch fix these issue, it process the logical volumes at their time not after all processing fstabs.

bigbiff ad58e1bfae repack: move sbin to /system ramdisk and update repacking
for android-10

This will support updating the ramdisk to a different
compression format and co-exist with magisk.

We are also cleaning up and removing non android-10
api makefile actions.

We are also moving twrp repacking to its own class. We
check the new ramdisk format and if it's different
we have magisk compress using the new ramdisk format.

bigbiff 25d25b9e67 log storage: change AB device log storage to /data/recovery
This patchset is now exlcuding /data/cache from backup, and removing it
from the wipe exclusion list to prevent errors on restore and wiping
/data.

This patchset changes the directory from /data/cache to /data/recovery for TWRP
to store logs and other file information. This will help with AB
devices that don't want recovery to mess with /data/cache.

This patchset will make ORS use /data/cache for AB devices.

Remove policy code because we don't need to set a policy for the
recovery directory.

bigbiff 7ba7500953 decrypt: AOSP 10 requires the use of fscrypt
fscrypt aosp doc: https://source.android.com/security/encryption/file-based
kernel fscrypt doc: https://www.kernel.org/doc/html/v4.18/filesystems/fscrypt.html

This commit implements the ability for TWRP to use fscrypt to decrypt
files on the fscrypt implementation. It has been implemented mostly
in a new successor library to e4crypt called libtwrpfscrypt. Most of the
code was ported from AOSP vold.

Notable updates include:
 - updated policy storage by libtar
 - lookup of fbe policies by libtwrpfscrypt
 - threaded keystore operations

Big thanks to Dees_Troy for the initial trailblazing
of encryption in TWRP.

bigbiff ee7b7ffba4 super partition: mount super partitions using fs_mgr
We are now requiring fstab v2 for android-10+ trees. You can
specify twrp flags using /etc/twrp.flags to label and
annotate partitions.

This patchset uses fs_mgr to load the super partition and build
device mapper blocks off vendor and system depending on the slot
in use. These are mapped to partitions in TWRP and allowed to
be mounted read-only. The super partition is also mapped into a
TWRP partition in order to backup the entire partition. You cannot
backup individual device mapper blocks due to the device can only
be read-only. Therefore you cannot write back to the device mapper.

Chaosmaster f6e42ce390 Implement autodetection for SAR, based on the installed system
This will detect whether SAR is present in the currently installed
OS and set the property ro.twrp.sar accordingly.
After setting the property it will call the bootscript
/sbin/sarsetup.sh (if present) to give device maintainers the
option to do setup operations depending on SAR-status, such
as modifiyng the fstab.

If no system is detected and AB_OTA_UPDATER is defined or built with
Android 10 and upwards, it will fallback to using SAR, otherwise it
will use ro.build.system_root_image as basis for deciding whether SAR
is required or not.

The property ro.twrp.sar will also be used by
TWPartitionManager::Get_Android_Root_Path()

This allows maintaining a single TWRP-build for devices switching
to SAR for Android 10.

The default behavior (when no system is installed)
is determined by the build-flags AB_OTA_UPDATER and
BOARD_BUILD_SYSTEM_ROOT_IMAGE

dianlujitao 4879b37b5d Fix the long broken format function
* For EXT2/3:
   * Align mke2fs options with Android 9.0 fs_mgr_format.cpp.
 * For EXT4:
   * Note that make_ext4fs is still in use on Android 8.1 to workaround
     a FDE encryption bug even though mke2fs has become the default
     choice. The bug is fixed in Android 9.0+.
 * For F2FS:
   * Drop the broken "-r" option, it's never ported to O, explicitly
     pass number of sectors instead.
   * Keep all options aligned with Pie fs_mgr.
   * Check existence before start wiping, as Wipe_EXT4 does.
 * For all:
   * Calculate block size at runtime, and reserve the space specified
     via negative "length" option from fstab. Note that positive length
     will be ignored.
   * If the partition has crypto footer, and "length" is not specified
     in fstab, automatically reverse CRYPT_FOOTER_OFFSET (16384).
   * Remove the default crypto key location: footer, this is a bad
     assumption since most partitions don't use encryption! We need to
     know the real situation to decide whether to reserve crypto footer
     on format.
   * If the current action is "wipe" or "change filesystem", wipe crypto
     footer or block device after mkfs if the partition is
     unencrypted or undecrypted (e.g., wrong password).
   * If the current action is "format data", unconditionally wipe crypto
     footer or block device.

Ethan Yonker 6e8c27a52b Support v2 fstab format
Auto detect and support both the v1 and v2 fstab formats
Support putting TWRP style flags in a separate /etc/twrp.flags file

twrp.flags format is the same as twrp.fstab (v1 with TWRP flags)

Support using a wildcard in a block device and find all partitions:
/usb-otg vfat /dev/block/sda*

Support using sysfs entries (voldmanaged) and read uevents and scan for
wildcard partitions from uevent data. (twvold?)

May not be complete for some of the newer flags found in fstabs in newer
build trees and there is a slim chance of a crash if the user removes a
removable device while TWRP is performing actions. May need to add some
kind of mutex to prevent the 2 threads from causing this crash. We need
to start somewhere though and this change is pretty innocuous when not
using a v2 fstab.

This patch is to refactor twrpDigest using polymorphism

Use SHA2 from libcrypto. SHA2 is default if device has libcrypto.

Change string MD5 everywhere to use digest or Digest instead. Updated
string tags to digest. Translation will be required.

Switch out digest code into a driver class from partitionmanager.

SHA2 is better for digest creation due to decreased collision space
compared to MD5 and SHA1.

bigbiff ce8f83c48d ADB: Add adb backup for TWRP.
Functionality for client side to backup
tar and image streams over adbd to the client under backup.ab.

Using adb backup on the client side you can backup the partitions
TWRP knows about.

On the client side you can do the following:
adb backup -f <filename> --twrp <options> where options are
--compress: compress data
system: backup system
cache: backup cache
data: backup data
boot: backup boot
etc for each partition.

You can string multiple options,
i.e. adb backup -f <filename> --twrp --compress cache system data

adb backup in TWRP will take any option corresponding
to TWRP fstab partitions, e.g. efs boot as well.

If you do not specify the filename with the -f option,
adb will backup your data to a filename backup.ab on the client.
You can then rename the file and encrypt it with desktop tools.

If you don't want to use command line arguments:
adb backup --twrp

will bring up the gui and allow you to choose partitions
from the backup page.

To restore the backup use the following convention:
adb restore <filename>

Structures are used to store metadata in binary inside
of the file itself. If the metadata structure is modified,
update the adb version so that it will invalidate older
backups and not cause issues on restore. When restoring,
we currently do not support picking specific partitions.
It's all or nothing.

Ethan Yonker 472f506817 Improve progress bar handling for backup / restore / image flash
The progress bar will now be updated during image backups, restores
and during image flashing (except for sparse images which will require
significant changes to libsparse, and except for mtd nand using
flash_utils).

The progress bar will now be updated mid-file for file systems (tar) so
the user will see changes even during large file backup / restore.

Add a new progress tracking class to simplify handling of progress bar
updates. The class will only update the progress bar 5 times a second to
reduce the CPU load from updating the GUI frequently which does affect
backup times.

James Christopher Adduono d6f94acc9a Allow restoring to read-only file system
This allows the restoration of firmware or modems on read-only
mounted file systems. If the user is able to make a backup of
these partitions, it would only make sense they be allowed to
restore that backup. The current handling is dangerous in that
it happily wipes, but refuses to restore. :)

Note that it would be preferable to use the backup=emmc flag
instead in most cases, added by change:

Ethan Yonker b5fab76bea Replace fix permissions with fix contexts for emulated storage
Fix permissions rarely fixed anything on more recent versions of
Android and usually made things worse. Instead we will replace it
with a more dumbed down option that should fix contexts on
/data/media with a few improvements to ensure that contexts get
fixed for multiple users and on adopted storage.
