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.

BUG: Some devices having issues with mounted apex while flashing some packages.
TEST: Added a device specific script in the device tree, which deloaded the apex, which are not needed and its fine.

In order to make sure the crypto state and type is set
properly if the device is encrypted, move this check to
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.

For the back-up menu, we can detail what the super partition includes by
aggregating one of BOARD_GOOGLE_DYNAMIC_PARTITIONS_PARTITION_LIST or
BOARD_QTI_DYNAMIC_PARTITIONS_PARTITION_LIST.
We comma-separate the list and capitalise the first letter of each
dynamic partition.

fastbootd is a userspace daemon that runs in the recovery
ramdisk. It allows writing single partitions to the super
partition via fastboot CLI. When TWRP sees the fastboot option
in the misc partition during startup, it will start with
the fastbootd page and fastbootd running. Otherwise it will
run recovery normally.

* 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.
This fixes the decryption issue.
Translate more partitions i.e., ODM, Product.
Added more partitions in unmount partitions.

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.

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.

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.

This patch uses the loop device to mount files under
/sbin/ from /system/apex in order for the device to
use libraries or other files store inside these files.
Each apex file is mounted over a loop device into a
directory correpsonding to the apex filename under
/sbin/.
Once apex mounting is completed, TWRP will set a
property twrp.apex.loaded to true so that init
can use them as a LD_LIBARY_PATH source.

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.

* Always use "/system" to interact with the frontend and replace it
with the detected path before taking actions.
* Don't replace the pretty display name and backup name set during
processing fstab after wipe. This improves UX and ensures that the
system backup is always named system.ext4.win despite the actual
mount point is /system_root so TWRP is able to recover either SAR or
non-SAR backups.
Change-Id: Ie2594d2678d0c75ce25c0d1087d47b035b3f10e9
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

ANDROID_ROOT environment variable is also used by other Android
components thus it should ALWAYS be /system in order not to break other
tools. On the other hand, AOSP does have a system property to indicate
system-as-root, just make use of it.

This allows flame to boot TWRP. Still will need to work on
super partition for vendor and system access.
The plan will be to cherry-pick any updates to android-9.0
through gerrit.twrp.me to this branch as a WIP.
Set TW_INCLUDE_REPACKTOOLS := true
Must also have:
AB_OTA_UPDATER := true
Use magiskboot and provide GUI options to allow users to repack
their existing boot image to install TWRP (or kernels) so we can
stop having to provide installation zips for AB devices. There is
also an option to try to fix a recovery bootloop if the kernel
has been patched to always boot the ramdisk for root, etc.
You will need to pull the below repo into external/magisk-prebuilt

* 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.

This update splits old MTP code and new MTP code from Google
into two trees, legacy and ffs. Depending on the SDK level,
the build system will select the correct version. The reason
for separating the versions out are due to older android trees
not supporting the updated MTP code from Google.
Most MTP code is from Google, with additions needed from
implementing the Java functions in C++ for TWRP and FFS.
We assume if you are in android-9.0 or above, your kernel
has support for FFS over MTP. Verify that your init.rc
is mounting the MTP FFS driver to the proper location.
