b92e5b5c48 Find a zoned partition automatically
Since we cannot create a gpt table on zoned LU, we cannot make a generic symlink
from it. Instead, let's make it by uevent, "/dev/block/by-name/zoned_device".
Note that, we support only one zoned device in the system.

5140f3ad47 init: Wait for daemon to fully spin up all threads
During selinux transition, daemon will notify `init` process
by writing to file "/metadata/ota/daemon-alive-indicator".

Init will wait until daemon notifies it. Furthermore, daemon
will only write to that file once all threads are spin up
and attached to dm-user misc devices.

Once snapshot-merge is completed, this file will be removed.
Additionally, during boot, init will also ensure that
there are no stale files and will try to remove just
before selinux transition.

Bug: 262407519
Test: OTA on Pixel - Verify new file exits and init waits until daemon
is fully up.

6b88d1684c Parser::ParseConfigFile returns Result<void>
ParseApexConfigs() uses Parser::ParseConfigFile() to parse .rc files in
the target apex. ParseConfigFile() returning bool (with logging on
error) doesn't propagate the error message back to the callers
(including apexd or PackageManager).

We'd better to migrate other Parse*() methods of Parser class to return
Result<T>. But this change focuses on plumbing error progagation for
APEX configs.

f85317fb43 Make an error message more informative
From

system/core/init/init_test.cpp:219: Failure
Failed
Value of: service-&gt;Start()
  Actual: createProcessGroup(0, 15611) failed for service 'console'
  Expected: is ok

The above error message does not contain enough information to
root-cause the test failure. Hence this CL that makes an error message
more informative.

f1e3bfff40 host_init_verifier: add check for root services and linux capabilities
If a service that runs under root doesn't have the capabilities field in
it's definition, then it will inherit all the capabilities that init
has.

This change adds a linter to detect such services and ask developers to
explicitly specify capabilities that their service needs. If service
doesn't require any capabilities then empty capabilities fields should
be added in the service definition.

The actual access control list on what capabilities a process can use is
controlled by the SELinux, so inheriting all the init capabilities is
not a security issue here. However, asking services to explicitly
specify the capabilities they need is a good defense-in-depth mechanism.

So far this linter only checks the services on /system partition.

All currently offending services are added to the exempt list. I will
work on fixing some of them in the follow-up changes.

ae412804ca Run the console test with /dev/null
The availability of /dev/console varies across different devices and
even across different build variants (ex: userdebug/user). Instead of
relying on the device-specific condition, use the /dev/null as the
console device for the test.

Inseob Kim
a049a9928b Kill services even when cgroups is disabled
process_cgroup_empty_ is used to indicate that a service is already
killed or not. If cgroup support lacks, services cannot be killed
because process_cgroup_empty_ is always true.

This change fixes it by not assigning process_cgroup_empty_ as true.
Instead, make KillProcessGroup send signals even when cgroup is
disabled. Also DoKillProcessGroupOnce() is updated so it returns a number of killed processes, excluding already dead processes. This behavior agrees with its name (DoKillProcessOnce), and it prevents regression upon missing cgroups, because kill(-pgid) will always
"succeed" so KillProcessGroup will loop even when all processes are
already dead.

d6bf86b8cf Support sysfs changes in the Linux 5.15 kernel.
DM_DEV_CREATE no longer creates sysfs nodes. Note this in ueventd and
add some helper APIs to libdm, so devices can be created with a

devices was wrong.
