When a user issues `fastboot flash vendor_boot:foo ramdisk.img`, the fastboot driver
fetches the vendor_boot image from the device,
determines if `foo` is a valid vendor ramdisk fragment,
repacks a new vendor boot image, then
flash the vendor boot image back.
This requires vendor boot header V4.
As a convinent alias, `fastboot flash vendor_boot:default ramdisk.img`
flashes the whole vendor ramdisk image. This works on vendor boot header
V3 & 4.

The `fastboot fetch` command is a wrapper around
the fetch protocol. It:
- getvar max-fetch-size
- get the size of the partition
- read the data by chunks, chunk size = max-fetch-size.
The name of the partition is passed directly to the device
(with the usual has-slot magic for flashing etc.) If we support
fetching partitions other than vendor_boot in the future, no change
in the driver is needed.

Some devices, such as the Essential PH-1, don't have an
updated bootloader and the bootloader is appending an extra
underscore.
This patch works around that issue by sanitizing the slot to be
inline with modern expectations.
Offending commit: 42b18a518b
Most of the commit above is not needed because an underscore + slot
is automatically appended when flashing to a partition. Normally, this
would result in something like boot__b instead of boot_b, where b is the
current slot.
Test: flash an image on mata without specifying slot, boots

SnapshotManager::New() is now preferred in recovery. Previously we used
NewForFirstStageMount(), which is technically incorrect as that enables
code paths specifically for first-stage init.
We also explicitly label the snapuserd context, since rootfs in recovery
has unlabelled files.
Finally, we add a timeout to internal calls to
CreateSnapshotsAndLogicalPartitions. Without this, WaitForDevice() calls
will terminate immediately, which breaks VABC given the more complex
device stacking that is created.

Right now fs_mgr_overlayfs_teardown() does slightly different things
when called from the userspace or recovery. This is accomplished by many
runtime checks, runtime assumptions and conditional execution of code.
This makes the control flow of the function very hard to follow, and
assumptions becomes more fragile as the function becomes more complex.
This CL forks fs_mgr_overlayfs_teardown() and removes "recovery" bits
from it. A new entry point TeardownAllOverlayForMountPoint() is added
for recovery.
Recovery (fastbootd) should call TeardownAllOverlayForMountPoint() to
teardown overlays of all sources (cache dir, scratch device or DSU).
While fs_mgr_overlayfs_teardown() should only be called from the
userspace.
Also apply some linter suggestions.

This is a re-landing of the original CL, with a few changes:
- The correct device is now returned in MapUpdateSnapshot.
- The old API is used for tests, and the new API is only tested when
used on a VABC device.
- A sync() call has been added to ensure that writes to the base and
target snapshot devices have been fully flushed. This makes
IsPartitionUnchanged detect the MapUpdateSnapshot bug.
Implement OpenSnapshotWriter for non-compressed Virtual A/B. This is
done by adding an OnlineKernelSnapshotWriter class, which forwards all
writes to a dm-snapshot block device.
This also introduces a new ISnapshotWriter class which extends
ICowWriter, and adds features specific to libsnapshot (versus ICowWriter
which is intended only for the new COW format). The OpenSnapshotReader
call has been moved here since the writer retains all the information
needed to create the reader.
To test the new call, vts_libsnapshot_test has been modified to use
OpenSnapshotWriter.
As part of this change, all consumers of libsnapshot must now link to
libsnapshot_cow.

The build system has added the new target named 'linux_cross' which is
the cross-compiled (i.e. arm on x86) host target. libfastboot is now
configured to use usb_linux.cpp not only for linux_glibc (which is the
native host target using glibc), but for all Linux-based host targets
including linux_glibc, linux_bionic, and the new linux_cross.
Note that the device target 'android' is also included in the 'linux'
target. But that doesn't cause a problem because libfastboot is a host
library which is not enabled for the device target.

Status() is called with an empty string to handle `fastboot oem`
commands. This currently emits a set of spaces and sets
last_start_time such that the epilog can track the time spent in this
command. Emitting the spaces is problematic however, since it results
in the follow:
$ fastboot oem device-info
(bootloader) Verity mode: false
(bootloader) Device unlocked: true
(bootloader) Device critical unlocked: true
(bootloader) Charger screen enabled: true
OKAY [ 0.000s]
Finished. Total time: 0.000s
If we skip emitting the spaces, then we get the correct result:
$ fastboot oem device-info
(bootloader) Verity mode: false
(bootloader) Device unlocked: true
(bootloader) Device critical unlocked: true
(bootloader) Charger screen enabled: true
OKAY [ 0.001s]
Finished. Total time: 0.001s
There are no other uses of Status() with an empty string, so this
changes won't impact other commands.

It's not possible to programmatically determine which fastboot mode a
device is in, without sending a getvar:is-userspace query. Unfortunately
this is not possible asynchronously, and may interrupt other queries
being processed.
This patch changes fastbootd's USB interface name to "fastbootd". Note
that tools use the protocol number/class and not this string, so it
should be safe to extend. When using "fastboot devices", the interface
name is now listed if set. Note that currently only the Linux version of
the fastboot tool is capable of reading the interface name.

There is a chance that devices are failing to reboot in the lab due to
sync() taking explicitly long during reboot. Let's add the sync()'s

set_active command must be restricted when a merge is in progress.
In addition, introduce a "snapshot-update merge" command for assisting
with erase requests when a merge is in progress. As in recovery, this

This introduces two new commands to the fastboot protocol:
- getvar snapshot-update-status - Return "none", "snapshotted", or
"merging" depending on the current status set by the boot control
HAL.
- snapshot-update [cancel] - Cancel any pending snapshot-based updates
via the boot control HAL. After this, the HAL should return
MergeStatus::CANCELLED and "update-merge-status" should be "none".
If no argument is specified, the snapshot-update-status is returned
via an INFO response.
Bootloaders are expected to implement this in a manner consistent with
the boot control HAL.
Fastboot-based tooling should expect wipes of userdata to fail when
update-merge-status returns "merging". Thus, the force flag now cancel
any pending snapshots.

load_buf_fd() attempts to find the size of the file that it is about
to load by first calling sparse_file_import_auto() then using
sparse_file_len() upon success or falling back to the file size on the
filesystem on failure.
This is problematic however as sparse_file_import_auto() creates a
sparse_file out of the normal file, but does not resparse it, so an
assertion fails during the sparse_file_len() call.
This is fixed by using sparse_file_import() instead. This will fail
in the case that the file is not sparse and the call to
sparse_file_len() will be properly skipped.

Currently, during a 'fastboot flashall/fastboot update', the 'getvar
max-download-size' command is issued once to the device when it is in
bootloader mode and the same value is used even after the device boots
into fastbootd. If the max-download-size returned by bootloader is
greater than the max-download-size in fastbootd, this could break flash
as large images are broken down into chunks before downloading by using
the max-download-size variable. This will cause fastbootd to return
an error since it checks whether the buffer being downloaded has a size
greater than the max-download-size limit.

As part of a refactor, commit db511207ed
added a timeout for receving responses for commands. Unfortunately,
the timeout is optimistic as to how quickly target devices can complete
such operations. Flash and erase commands can be quite slow on devices
with traditional flash chips. The fastboot protocol is already adept
at handling such cases because it allows for sending INFO packets during
these periods. We may receive one or more INFO packets during tehse long
operations. Every time we receive an INFO packet, it proves the remote
end is alive, but busy, which should reset our timeout timer.

On retrofit devices, if both slots contain dynamic partition builds,
then "flashall" will attempt to write secondary images to dynamic
partitions in the other slot. At worst, this can fail with an error. At
best, it will result in the "other" partition not being mounted on first
boot.
This patch therefore deletes logical partitions for secondary images, on
retrofit devices only. On a Pixel device on the "b" slot, this means
"system_a" and "vendor_a" will be deleted before flashing, and therefore
system_other and vendor_other will be flashed to physical partitions
instead.

Retrofit devices will have two super partitions, spanning the A and B
slots separately. By design an OTA will never cause "A" or "B"
partitions to be assigned to the wrong super. However, the same is not
true of fastbootd, where it is possible to flash the inactive slot. We
do not want, for example, logical "system_a" flashing to super_b.
When interacting with partitions, fastbootd now extracts the slot suffix
from a GetSuperSlotSuffix() helper. On retrofit devices, if the partition
name has a slot, that slot will override FastbootDevice::GetCurrentSlot.
This forces partitions in the inactive slot to be assigned to the correct
super.
There are two consequences of this. First, partitions with no slot
suffix will default to the current slot. That means it is possible to
wind up with two "scratch" partitions, if "adb remount" is used on both
the "A" and "B" slots. However, only the active slot's "scratch" will be
visible to the user (either through adb or fastboot).
Second, if one slot does not have dynamic partitions, flashing will
default to fixed partitions. For example, if the A slot is logical and B
is not, flashing "system_a" will be logical and "system_b" will be
fixed. This works no matter which slot is active. We do not try to
upgrade the inactive slot to dynamic partitions.

On retrofit devices, it is easy to accidentally overwrite
system/vendor/product by flashing system in the bootloader. The reason
is that GPT system_a is really the super partition, and the bootloader
doesn't know it.
Addressing this in bootloaders would require two separate commands: one
that rejects flashing system/vendor/product, and another for
expert/factory use that would allow direct flashing.
This patch introduces protection into the host fastboot tool instead.
It's not mutually exclusive with bootloader changes; having protection
in the host tool affords us better and consistent UI. However it does
rely on users having newer builds.
With this change, the following will not work in the bootloader:
fastboot flash system # or vendor, product, etc
The message is the same whether or not the device is a retrofit. To
continue anyway, you can do:
fastboot flash --force system
If we decide on bootloader protection as well, the --force flag can be
re-used.

This patch adds a new variable, "super-partition-name", to query the
name of the super partition (with a slot suffix if it has one). The
fastboot flashing tool has been updated to query this variable.
Since the super partition name can no longer be determined without
fastbootd, the presence of super_empty.img is used to test for
dynamic partition support rather than the presence of a super partition.

The purpose of this code was to support preserving partitions across a
flashall operation. Since we are not supporting persistent read-write
partitions, this merging code is effectively useless - it is preserving
only partitions that will be deleted.
Additionally, this code does not merge partition group changes, since
doing so accurately is difficult. Partition size changes aren't sent
until after update-super resolves, so a valid re-grouping could be
rejected during update-super if the existing partitions are too big.
This patch removes the update-super merging code until a use case comes
along and we can properly evaluate how it should work.
