A previous change moved property_service into its own thread, since
there was otherwise a deadlock whenever a process called by init would
try to set a property. This new thread, however, would send a message
via a blocking socket to init for each property that it received,
since init may need to take action depending on which property it is.
Unfortunately, this means that the deadlock is still possible, the
only difference is the socket's buffer must be filled before init deadlocks.
This change, therefore, adds the following:
1) A lock for instructing init to reboot
2) A lock for waiting on properties
3) A lock for queueing new properties
A previous version of this change was reverted and added locks around
all service operations and allowed the property thread to spawn
services directly. This was complex due to the fact that this code
was not designed to be multi-threaded. It was reverted due to
apparent issues during reboot. This change keeps a queue of processes
pending control messages, which it will then handle in the future. It
is less flexible but safer.

This steps up our garbage collection threshold over time when mounting
userdata with checkpointing=disable for f2fs. With this scheme, we step
up the percent of disk we will tolerate being unusable during
checkpointing. At 100%, the filesystem will be able to always mount.
This means we will attempt to mount at most 10 times, for a max time of
about 50 seconds.
Also logs mount time under ro.boottime.init.mount.[target]
If the device does not support checkpoint=disable:[n%], it will mount
with checkpoint=disable, which is equivalent to checkpoint=disable:0%

libselinux is currently being copied to APEXes. This is risky because
the library is not designed to be portable; part of it is tied to the
specific version of the Android that it was developed for.
This change fixes the problem by declaring that the library supports
a stub with the list of C APIs that are included in the stub. Then there
is only one copy of libselinux in /system/lib and other APEXes use the
copy by dynamically linking to it.
Also, adbd no longer statically links to it, because doing so brings
libselinux in it.

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).

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.

In case of GSI on DSU, /data is mounted on the following stack:
userdata -> userdata_gsi -> actual block device, and fstab returned from
ReadDefaultFstab() function will say that /data should be
mounted onto userdata_gsi. This configuration wasn't supported.
To support it, fs_mgr_get_mounted_entry_for_userdata now unwinds the
dm-device stack /data is mounted onto, and for each entry in fstab
resolves corresponding block device (in case of logical partitions by
asking DeviceMapper to resolve name -> path, and for other cases by
reading a symlink), and then checking whenever resolved block device
belongs to the unwinded stack.

liblog is a platform library that provides stable C API. There is no
need to include the library, especialy by statically linking to it, in
any APEX. It not only wastes the storage/ram, but also is incorrect
because the socket interface to logd which is implemented in liblog is
not guaranteed to be stable.
Fixing this issue by converting static_libs: ["liblog"] into
shared_libs: ["liblog"], in which case the dependency to the library
is satisfied via the stub variant of the library.
As a result, we could restrict the availablity of the library to
the platform and the runtime APEX.
