Easiest way I could find to determine if we have the old or the
new mkfs.f2fs version is to pipe the usage output to grep and
grep the output for "reserved" and redirect the output to a file.
If the file has any data in it, then we must have the old
mkfs.f2fs that uses -r.

* 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.

cryptfs.cpp based on CAF tag LA.UM.7.3.r1-05900-sdm845.0
Used CAF because AOSP no longer contains code for qcom's hardware
crypto.

instead of hard-coded /system path
I updated most of the references I found,
but there might be more
For devices that have to mount system at /system_root,
this allows system to be bind mounted to /system
and detected properly by TWRP

Building in 9.0 may require you to add a flag to your twrp fstab
with the fileencryption details like:
fileencryption=ice:aes-256-heh
Verify this against your device's stock fstab of course.

* /persist can be mounted early while TWRP is parsing the fstab so
as soon as the partition is parsed, mount and adjust the time
accordingly.
* Store a backup settings file on /persist. Having a 2nd copy of
the settings file in the /persist partition allows for early
reading of the file and adjust timezone and brightness to user
preference while still on TWRP splash.
* Add the qcom ats time offset in TWRP settings file and use it
if no better ats file is found. This will also allow devices
with a persist partition, but no ats files in it, to adjust
the time offset during early boot.
* Use /persist/time/ as Qualcomm time fix source, based on

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
and inheritance to use the same call patterns for creating and
reading a digest. Now a library.
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.
See https://en.wikipedia.org/wiki/SHA-2

-Change backup display name to say that we are excluding storage
-Add warning message during backup of any partition with data media
-Also eliminate unused variable from twrpTar class
Maybe this will make the people in issue 276 happy, but probably not because
they already lost their data, or because the warning text is yellow instead of
red.

The PartitionSettings struct contains some data elements that are duplicates
of data elements in the TWPartition class that is contained within the
PartitionsSettings.Part element. We will eliminate this duplication to help
reduce the chances for programming bugs.
Specifically, this fixes problems where the current file system does not
match the backed up file system.

this is to prevent a race condition to occur when mounting an adopted
storage volume just after it was decrypted. After setting up the
decrypted volume using cryptfs_setup_ext_volume(), Decrypt_Adopted()
immediately calls Mount(), which will call Check_FS_Type(), which will
fail in blkid_new_probe_from_filename, as the device node was not
created yet.

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.

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.

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:

Conditionally run Add_MTP_Storage() after wipe if:
1) is wiped successfully
2) is storage (already implemented)
3) mount succeeds
Previous to this commit, Add_MTP_Storage() was called before mounting
storage, which fails. Mounting storage right after wipe should not be
a problem since Update_System_Details() does it anyways (and doesn't
complain if already mounted).

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.

Secure block discard/trim was fixed by:
https://github.com/CyanogenMod/android_external_f2fs-tools/commit/6b39b93d83ab4ccb1913ecbc7a5a3e16766a011f
Once fixed, formatting using discard/trim takes a LONG time. Other TWRP
formatting methods are already insecure. It doesn't make sense for this
one type of partition to have secure wipe when none of the others do.

* Fix several %s --> {1}
* Be consistent in usage of cancelled vs. canceled (both spellings
acceptable)
Tip for finding strings missing from language files:
1) Find all messages:
egrep -hr "gui_msg.+=" > /tmp/msgs.txt
2) Regex replace to trim them down
WHAT: ^\s+gui_msg(?:[^"]+)"([a-zA-Z0-9_]+)=([^"]+).+
WITH: $1
Note that $2 can be used to retain the message
3) Find missing strings:
for i in $(cat /tmp/msgs.txt); do
if ! grep -q $i gui/theme/common/languages/en.xml; then
echo $i;
fi
done

-Improve code for partitioning sdcards
-Allow user to select a device for partitioning (must be removable)
-Use sgdisk to partition sdcards
-Set default sizes for ext and swap to 0
-Change increments for ext to 256MB and swap to 64MB
Note: sgdisk is included in 6.0. I have included a static prebuilt
sgdisk for trees that do not have sgdisk, however the prebuilt
sgdisk is a decent bit larger than the old parted binary. The old
parted binary is quite old at this point and we only have it for
armv7a. sgdisk should be maintained by AOSP and can be built from
source so it should work across architectures.

CM-13 tree completely changes the names of the binaries that are created
for ntfs-3g. If we are using a CM-13 tree (CM SDK 4) make sure the
dependencies and relinking are adjusted accordingly.
Also, adapt partition code so it can make use of whichever set of
binaries are present.

AMLogic based device uses paths like /dev/block/recovery and the
stock init binary either deletes or does not create mmcblk0p12
which breaks TWRP because TWRP cannot match up the path / name.
The ioctl method is probably more reliable anyway and certainly
should be faster.

This is similar to https://gerrit.omnirom.org/#/c/14014
A lot of the features built in the older patch set have been split
out into separate patches, most of which have already been merged.
The remaining functionality here should all be directly related to
language selection and loading. We always load English as a base
before loading other languages over the top of the base. The idea
is that if another language is missing a translation, then we will
still display the English.
Maybe still to do: read the /cache/recovery/last_locale file and
load a language based on that. For me, this file contains just:
en_US
We probably won't bother with region specific translations so we
would have to look at either trimming off the _US or using some
other method like perhaps a symlink or a combination of the two.
Thanks to _that for twmsg.cpp class

Note: Only works on ext2/3/4 partitions. Only tested on ext4.
We can use this in some cases to resize the data partition if an
incorrect fstab caused recovery to not reserve the 16KB for a
crypto footer.
Sometimes the BoardConfig for a custom ROM does not have the
correct size for the system partition and if the ROM flashes a
raw system image, that image will not take up the full block
device. Running resize2fs can fix the size and may allow more
room in the system partition for customizations like busybox or
a larger gapps package.
Sometimes flashing a factory image may flash userdata with an
image with a file system that does not take up the full size of
the block device (e.g. factory images for the Nexus 6 will flash
userdata with a ~24GB userdata image, wasting ~30GB of space).
Using resize2fs we can easily fix this issue without having to do
a full format data.

Mounting system as rw can prevent future OTA updates. The purpose
of this patch set is to prevent TWRP from mounting sytem as rw on
the first boot. Device maintainers should update their twrp.fstab
files on these devices to include an additional line:
/system_image emmc /dev/block/../system
This line will allow TWRP to create a raw system image backup to
ensure that the user can return to an original state for future
OTA updates.

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.

Implement a pipe between TWRP and MTP to allow TWRP to tell MTP
to remove storage partitions as they become unavailable (e.g.
during a wipe, unmount, etc) instead of disabling MTP completely.
This includes some fixes and improvements in destructors to
properly remove / delete various items. This also means that we
will not be toggling adb off and on quite as often.
I do not like that we had to add another thread, but we were
unable to use select() on the mtp_usb character device because
this device does not support polling. Select always returned
indicating that the mtp file descriptor was ready to be read and
the resulting read would block. The read block prevented us from
being able to include reading of the pipe between TWRP and MTP in
the main MTP thread.
We might want to add a return pipe letting TWRP know if the
removal of the storage device was successful, but I am not sure
how we want to implement this. It would invovle timeouts in both
TWRP and MTP to ensure that we returned a failure indicator in a
timely manner to TWRP and prevent deleting the storage device in
the case of a failure. Right now we make no attempt to ensure that
an MTP operation is underway like a large file transfer, but we
were not doing anything like this in the past. In some respects we
have limited control over what happens. If the user installs a
zip that unmounts a storage partition, we will not know about the
change in storage status anyway. Regular Android does not have
these troubles because partitions rarely get unmounted like in
recovery. At some point, we have to hold the user accountable for
performing actions that may remove a storage partition while they
are using MTP anyway.
Ideally we do not want to toggle the USB IDs and thus toggle adb
off and on during early boot, but I am not sure what the best way
to handle that at this time.

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

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.

Some devices (jewel, m8) have .android_secure at a non-standard
location. Allow a different partition to be specified as the home of
.android_secure using the fstab flag 'andsec'.
Using the /data/media variant of jewel as an example, recovery.fstab or
twrp.fstab could be edited like follows:
/external_sd vfat /dev/block/mmcblk1p1 flags=display="MicroSD";andsec
Note, this is NOT a method to move .android_secure in your ROM. Your ROM
must already write to this alternative location.

- Until the encrypted partition is decrypted, treat it as a disk image
instead of a filesystem so that it is properly backed up using dd.
- Make Partition::Wipe() use the filesystem from fstab for disk images
so that wiping an undecrypted /data makes it a plain unencrypted
partition again.
