Allow mapping of raw block devices (those without a partition table)
to partition names for first stage mount and ueventd. For example, a
block device `vdb` that contains only an ext4 metadata partition could
be mapped to `metadata` such that /dev/block/by-name/metadata is
created.
The mapping is provided by the `androidboot.partition_map` bootconfig
or kernel command line parameter.

The reason for two mount namespace (bootstrap/default) is that we have
two sets of different APEXes to activate. But in microdroid, we don't
need two separate mount namespaces because there's only one set of
non-updatable APEXes in built-in directories and payloads (passed from
host Android).

Currently there is no socket for daemon instances launched during the
selinux phase of init. We don't create any sockets due to the complexity
of the required sepolicy.
This workaround will allow us to create the socket with very minimal
sepolicy changes. init will launch a one-off instance of snapuserd in
"proxy" mode, and then the following steps will occur:
1. The proxy daemon will be given two sockets, the "normal" socket that
snapuserd clients would connect to, and a "proxy" socket.
2. The proxy daemon will listen on the proxy socket.
3. The first-stage daemon will wake up and connect to the proxy daemon
as a client.
4. The proxy will send the normal socket via SCM_RIGHTS, then exit.
5. The first-stage daemon can now listen and accept on the normal
socket.
Ordering of these events is achieved through a snapuserd.proxy_ready
property.
Some special-casing was needed in init to make this work. The snapuserd
socket owned by snapuserd_proxy is placed into a "persist" mode so it
doesn't get deleted when snapuserd_proxy exits. There's also a special
case method to create a Service object around a previously existing pid.
Finally, first-stage init is technically on a different updateable
partition than snapuserd. Thus, we add a way to query snapuserd to see
if it supports socket handoff. If it does, we communicate this
information through an environment variable to second-stage init.

This reverts commit 1c51525f66 because it
accidentally made reboot_on_failure be a no-op for all services. This
is because Reap() itself calls KillProcessGroup() on devices with a
vendor level >= R, which in turn sets SVC_STOPPING. I had overlooked
this somehow, probably because I didn't consider that a service can
consist of multiple processes.
It turns out that real FDE devices don't actually need the above commit
because FDE devices aren't allowed to have updatable apexes enabled, and
without updatable apexes enabled, apexd exits automatically and
therefore doesn't have to be stopped. This can be verified by using the
aosp_cf_x86_phone_noapex build target, rather than aosp_cf_x86_phone
which I had used for testing before. So just revert it for now.

If a bootconfig argument has a list of values, it has a space between
them in /proc/bootconfig.
Example:
BOARD_BOOTCONFIG := parameter=value1,value2,value3
In /proc/bootconfig, it looks like:
parameter = "value1", "value2", "value3"

"value1, value2, value3"
To keep consistent behavior with kernel cmdline the value string should be:

[Description]
In the Quiescent Reboot process,
the android init process will pass the reboot target name "quiescent"
to the kernel through reboot syscall.
Kernel will write the boot-quiescent flag
to the misc partition to notify the bootloader.
When rebooting, bootloader will be added to
bootargs androidboot.quiescent=1 to notify android .
In the new version of GKI,
the filp_open function is not allowed
so that it is impossible to write the quiescent flag
in the Kernel to the misc partition.

Add a new service flag SVC_STOPPING which tracks whether a service is
being manually stopped by init, and make the "reboot_on_failure" service
setting not apply when SVC_STOPPING is set.
This is needed for devices that use FDE, because otherwise the device
reboots during the following init script fragment:
on property:vold.decrypt=trigger_shutdown_framework
class_reset late_start
class_reset main
class_reset_post_data core
class_reset_post_data hal
... because that stops all services, including apexd which has been
marked with reboot_on_failure since
https://android-review.googlesource.com/c/platform/system/apex/+/1325212.
So init was killing apexd, then rebooting the device because apexd
"failed" due to having been killed. Making reboot_on_failure not apply
when init stops a service itself fixes the problem.

init starts services in "bootstrap" mount namespace until the "default"
mount namespace is ready even when init's current mount namespace is
"default".
apexd and linkerconfig are those processes to set up the mount
namespaces: apexd activates apexes and linkerconfig generates linker
configs.
Previously apexd is allowed to be started in the "current" namespace by
checking its "service name"(it should be "apexd"). But there can be a
certain environment apexd is started in a different way. For example, in
microdroid, apexd is started using "exec -- /system/bin/apexd --vm"
because it wants to run in a different execution mode.
So, instead of checking the service name, its executable's path is
checked against to allow apexd to be started in the current mount
namespace.

setting the build flag PRODUCT_SET_DEBUGFS_RESTRICTIONS true which in
turn sets ro.product.enforce_debugfs_restrictions true as well enables
sepolicy neverallow restrictions that prevent debugfs access. The
intention of the build flag is to prevent debugfs dependencies from
creeping in during development on userdebug/eng builds.

So we can extend platform policies with target specific compat rules.
This use case surface in the context of system only upgrade, when the
vendor policy cannot be updated, then the system_ext partition can
contain target specific compat policies.

Since recovery mode doesn't switch root to /first_stage_ramdisk, we need
to update the debuggable file paths for recovery mode. Without this,
adb needs to be authorized in recovery mode even with a debug
vendor_ramdisk.

Some devices might not have system_ext or product partitions. But init
has been refusing to use precompiled sepolicy because init always checks
system / system_ext / product hashes, regardless of existence. This
makes system_ext and product optional, so hash check can be skipped for
non-existing partitions. Of course system is always checked.

The androidboot.selinux property is loaded in a special way, because it

The androidboot.android_dt_dir property is special, because it is loaded
to find out where to get the other DT properties from, and those DT

Any service which is executed when Runtime apex is mounted, but
linkerconfig is not updated can fail to be executed due to missing
information in ld.config.txt. This change updates init to have a status
variable which contains if current mount namespace is default
and APEX is not ready from ld.config.txt, and use bootstrap namespace if
it is not ready.

This is a follow-up of I828ce999be6d786bf46dd5655dfda81d046906ab. The
change introduced a behavioral change that fstab is read twice: before
root is changed to /first_stage_ramdisk, and once again after that.
Previously, that happend only after the root is switched. That change
caused a problem when there is no fstab in DT and fstab is provided via
a file. The fstab file has been at
/first_stage_ramdisk/fstab.<hardware> because that file was supposed to
be read after the root switch.
With the change, init fails to read the fstab during the first attempt
because there is no /fstab.<hardware> at the moment. Here comes the
problem. Although it failed to read fstab, DoCreateService() is invoked
because ReadFirstStageFstab() doesn't report the failure; it returns an
empty fstab object. As a result, DoCreateDevices() is called but it
doesn't create the dm linear device because it couldn't find an fstab
entry having `logical` option.
Then after /first_stage_ramdisk becomes the root, the fstab file is
correctly read. But since the prior run of DoCreateDevices() is recorded
as 'done', init doesn't try to do that again; dm linear device is never
created. Then we fail to mount any of the logical partitions.
This change fixes the problem by modifying ReadFirstStageFstab()
function so that the failure is correctly reported back to the caller.
When it fails, DoCreateDevices() is not called.

Androidboot parameters are being moved from the kernel commandline to
bootconfig.
fs_mgr looks for these parameters in properties and falls back to
reading directly from /proc/cmdline. So both of these sources are
updated for bootconfig.
The androidboot parameters from /proc/bootconfig
are added as ro.boot properties, and fs_mgr will fall back to searching
/proc/bootconfig if it is too early.
Test: boot cuttlefish with androidboot.fstab_suffix and
androidboot.hardware in bootconfig and not in cmdline.
