61783ffc82 Prevent original libselinux.so to be unmounted
libselinux.so will be unmounted when magiskd starts. If magiskd restarts (like it died before boot completed), the files we want to unmount is the original files because the modified files is unmounted in previous start, which will causes many crashes due to missing libselinux.so.

c0a2e3674c Reset file context from adb_data_file
In some cases (like weird ROMs that allow init to relabel context from system_file), module files will have an incorrent context, which will causes module not working properly.

44f005077d Don't copy sepolicy.rule to /persist on boot
* This seems to be a logic that has been abandoned for a
   long time. Now we automatically choose which partition
   to store sepolicy.rule. Furthermore, touching /persist is
   what we should avoid doing whenever possible.

95c964673d Initialized _root properly
Fix #4204

`_root` is uninitialized for non-root nodes. And it will cause `module_node::mount` fail because it uses `root()`. Once the bug is triggered, signal 11 is received but Magisk catch all signals and therefore stuck forever.

faccessat() should return 0 when success, but it returns random number with errno == 0 in x86 platform.

It’s a side effect of commit bf80b08b5f when magisk binaries ‘corretly’ linked with library of API16 .. lol

da723b207a Allow 3rd party code to load pre-specializing
Magisk's policy is to never allow 3rd party code to be loaded in the
zygote daemon process so we have 100% control over injection and hiding.
However, this makes it impossible for 3rd party modules to run anything
before process specialization, which includes the ability to modify the
arguments being sent to these original nativeForkAndXXX methods.

The trick here is to fork before calling the original nativeForkAndXXX
methods, and hook `fork` in libandroid_runtime.so to skip the next
invocation; basically, we're moving the responsibility of process
forking to our own hands.

On devices where the primary storage is slow to probe it makes sense to
wait forever for the system partition to mount, this emulates the
kernel's behaviour when waiting for rootfs on SAR if the rootwait
parameter is supplied.

This issue was encountered with some SD cards on the Nintendo Switch.

16e4c67992 Significantly broaden sepolicy.rule compatibility
Previously, Magisk uses persist or cache for storing modules' custom
sepolicy rules. In this commit, we significantly broaden its
compatibility and also prevent mounting errors.

The persist partition is non-standard and also critical for Snapdragon
devices, so we prefer not to use it by default.

We will go through the following logic to find the best suitable
non-volatile, writable location to store and load sepolicy.rule files:

Unencrypted data -> FBE data unencrypted dir -> cache -> metadata -> persist

This should cover almost all possible cases: very old devices have
cache partitions; newer devices will use FBE; latest devices will use
metadata FBE (which guarantees a metadata parition); and finally,
all Snapdragon devices have the persist partition (as a last resort).

Due to changes in ec3705f2ed, the app can

the daemon decide a socket name, send it to the app, have the app create
the socket server, then finally the daemon connects to the app through
the socket.

ec3705f2ed Redesign of MagiskSU's sepolicy model
Introduce new domain `magisk_client` and new file type `magisk_exec`.

Connection to magiskd's always-on socket is restricted to magisk_client
only. Whitelisted process domains can transit to magisk_client through
executing files labelled magisk_exec. The main magisk binary shall be
the only file labelled as magisk_exec throughout the whole system.
All processes thus are no longer allowed to connect to magiskd directly
without going through the proper magisk binary.

Connection failures are silenced from audit logs with dontaudit rules,
so crazy processes which traverse through all unix domain sockets to try
connection can no longer check logcat to know the actual reason behind
EACCES, leaking the denied process policy (which is u:r:magisk:s0).

This also allows us to remove many rules that open up holes in
untrusted_app domains that were used to make remote shell work properly.
Since all processes establishing the remote shell are now restricted to
the magisk_client domain, all these rules are moved to magisk_client.
This makes Magisk require fewer compromises in Android's security model.

Note: as of this commit, requesting new root access via Magisk Manager
will stop working as Magisk Manager can no longer communicate with
magiskd directly. This will be addressed in a future commit that
involves changes in both native and application side.
