init.rc: disable kernel module autoloading
There is a longstanding bug where file-based encryption causes spurious
SELinux denials of module_request because it uses the kernel's crypto
API, and the crypto API tries to autoload kernel modules.
While this sometimes indicate missing kconfig options, it can still
happen even if all needed kconfig options are enabled. This is because
a crypto algorithm can be a composition like "hmac(sha512)", and the
crypto API will first look for the full composition before it
instantiates it using the components like "hmac" and "sha512". But
often an implementation of the full composition doesn't exist.
However, as far as I can tell, Android doesn't actually use kernel
module autoloading at all. First, Android never changes
/proc/sys/kernel/modprobe from the default of "/sbin/modprobe", yet this
isn't where modprobe is located on Android. Android's SELinux policy
contains a neverallow rule that ensures that only init (not even
vendor_init) can write to this setting, so vendors can't be changing it.
Vendors could potentially be setting CONFIG_STATIC_USERMODEHELPER_PATH,
which overrides the path of all usermode helpers including modprobe.
But this is a relatively new kconfig option, available only in
android-4.14 and later. Also, for a vendor to actually do this they'd
also need to extend the SELinux policy with a domain_auto_trans rule to
allow their usermode helper to be executed by the kernel.
Android does increasingly use kernel modules, and GKI (Generic Kernel
Image) will require them. However, the modules are actually inserted by
userspace by 'init', not autoloaded.
It's possible to disable kernel module autoloading completely by setting
/proc/sys/kernel/modprobe to an empty string. So, let's do that.
This prevents lots of spurious SELinux denials, and allows removing
unnecessary rules to allow or dontaudit the module_request permission.
Note: when the kernel doesn't have CONFIG_ANDROID_BINDERFS enabled, this
change exposes a kernel bug that causes a WARNING in get_fs_type(). To
avoid this WARNING, a kernel fix should be applied too -- currently
under discussion upstream
(https://lkml.kernel.org/r/20200310223731.126894-1-ebiggers@kernel.org).

Bug: 146477240
Bug: 148005188
Bug: 149542343
Test: Tested on cuttlefish and coral:
- Checked that /proc/sys/kernel/modprobe contains /sbin/modprobe
before this change, and the empty string after.
- Checked that if all SELinux rules for module_request are removed,
there are SELinux denials for module_request before this change
but none after.
- Ran lsmod both before and after and verified that the list is the
same, i.e. checked that this change doesn't break how Android
actually loads kernel modules.

Support for stopping/starting post-data-mount class subsets.
On devices that use FDE and APEX at the same time, we need to bring up a
minimal framework to be able to mount the /data partition. During this
period, a tmpfs /data filesystem is created, which doesn't contain any
of the updated APEXEs. As a consequence, all those processes will be
using the APEXes from the /system partition.
This is obviously not desired, as APEXes in /system may be old and/or
contain security issues. Additionally, it would create a difference
between FBE and FDE devices at runtime.
Ideally, we restart all processes that have started after we created the
tmpfs /data. We can't (re)start based on class names alone, because some
classes (eg 'hal') contain services that are required to start apexd
itself and that shouldn't be killed (eg the graphics HAL).
To address this, keep track of which processes are started after /data
is mounted, with a new 'mark_post_data' keyword. Additionally, create
'class_reset_post_data', which resets all services in the class that
were created after the initial /data mount, and 'class_start_post_data',
which starts all services in the class that were started after /data was
mounted.
On a device with FBE, these keywords wouldn't be used; on a device with
FDE, we'd use them to bring down the right processes after the user has
entered the correct secret, and restart them.

init: add builtin check for perf_event LSM hooks
Historically, the syscall was controlled by a system-wide
perf_event_paranoid sysctl, which is not flexible enough to allow only
specific processes to use the syscall. However, SELinux support for the
syscall has been upstreamed recently[1] (and is being backported to
Android R release common kernels).
[1] https://github.com/torvalds/linux/commit/da97e18458fb42d7c00fac5fd1c56a3896ec666e
As the presence of these hooks is not guaranteed on all Android R
platforms (since we support upgrades while keeping an older kernel), we
need to test for the feature dynamically. The LSM hooks themselves have
no way of being detected directly, so we instead test for their effects,
so we perform several syscalls, and look for a specific success/failure
combination, corresponding to the platform's SELinux policy.
If hooks are detected, perf_event_paranoid is set to -1 (unrestricted),
as the SELinux policy is then sufficient to control access.
This is done within init for several reasons:
* CAP_SYS_ADMIN side-steps perf_event_paranoid, so the tests can be done
if non-root users aren't allowed to use the syscall (the default).
* init is already the setter of the paranoid value (see init.rc), which
is also a privileged operation.
* the test itself is simple (couple of syscalls), so having a dedicated
test binary/domain felt excessive.
I decided to go through a new sysprop (set by a builtin test in
second-stage init), and keeping the actuation in init.rc. We can change
it to an immediate write to the paranoid value if a use-case comes up
that requires the decision to be made earlier in the init sequence.

As the presence of these hooks is not guaranteed on all Android R
platforms (since we support upgrades while keeping an older kernel), we
need to test for the feature dynamically. The LSM hooks themselves have
no way of being detected directly, so we instead test for their effects,
so we perform several syscalls, and look for a specific success/failure
combination, corresponding to the platform's SELinux policy.
If hooks are detected, perf_event_paranoid is set to -1 (unrestricted),
as the SELinux policy is then sufficient to control access.
This is done within init for several reasons:
* CAP_SYS_ADMIN side-steps perf_event_paranoid, so the tests can be done
if non-root users aren't allowed to use the syscall (the default).
* init is already the setter of the paranoid value (see init.rc), which
is also a privileged operation.
* the test itself is simple (couple of syscalls), so having a dedicated
test binary/domain felt excessive.
I decided to go through a new sysprop (set by a builtin test in
second-stage init), and keeping the actuation in init.rc. We can change
it to an immediate write to the paranoid value if a use-case comes up
that requires the decision to be made earlier in the init sequence.

init: add builtin check for perf_event LSM hooks
Historically, the syscall was controlled by a system-wide
perf_event_paranoid sysctl, which is not flexible enough to allow only
specific processes to use the syscall. However, SELinux support for the
syscall has been upstreamed recently[1] (and is being backported to
Android R release common kernels).
