320e08b8fb new supercall impl (#511)
* refactor: replace throne tracker with ksud token

* use snprintf

* refactor: new supercall impl

- Import the sukisu command

* disable seccomp for supercall users

* kernel: fmt clear

* kernel: Enable macro protection for sulog

- Only enabled on kernel versions greater than 5.10.245

* kernel: Refactor kprobe hooks and implement LSM hooks for improved security handling

* debug mode

* kernel: Add functionality to generate and validate authentication tokens for cmd_su

* kernel: Simplified manual SU command processing for code

* kernel: replace renameat hook with fsnotify

* Revert "refactor: replace throne tracker with ksud token"

This reverts commit aa2cbbf9cd.

* kernel: fix compile

* kernel: fix compile below 6.0

* Fix compile err; Add become_manager

* kernel: install fd for manager automaticlly

- extend to import the corresponding command

* manager: new supercall impl

* temp changes for ksud

* ksud: fix compile

* fix wrong opcode

* kernel: fix compile

* kernel: Fixed hook type and KPM status retrieval errors

* kernel: Fixed potential null pointer issue with current->mm in kernel version 5.10

When calling get_full_comm() within system call hooks, current->mm may be null (prctl). A fallback mechanism for current->comm must be added beforehand to prevent null pointer dereferences when accessing mm->arg_start/arg_end.

d5d2bb35d2 kernel: throne_tracker: offload to kthread tiann #2632
Run throne_tracker() in kthread instead of blocking the caller.
Prevents full lockup during installation and removing the manager.

By default, first run remains synchronous for compatibility purposes
(FDE, FBEv1, FBEv2)

Features:
- looks and waits for manager UID in /data/system/packages.list
- run track_throne() in a kthread after the first synchronous run
- prevent duplicate thread creation with a single-instance check
- spinlock-on-d_lock based polling adressing possible race conditions.

Race conditions adressed
- single instance kthread lock, smp_mb()
- track_throne_function, packages.list, spinlock-on-d_lock based polling
- is_manager_apk, apk, spinlock-on-d_lock based polling

This is a squash of:
https://github.com/tiann/KernelSU/pull/2632

Original skeleton based on:
`kernelsu: move throne_tracker() to kthread`
`kernelsu: check locking before accessing files and dirs during searching manager`
`kernelsu: look for manager UID in /data/system/packages.list, not /data/system/packages.list.tmp`

49b01aad74 kernel: Introducing Tracepoint Hook Type Support
Tracepoint is a predefined hook point in the kernel, compared to Kprobe,
it is more stable and has lower performance overhead, although compatibility
is relatively poor, it is still worth trying

By the way, we have also included the config definitions related to hook types
in Kconfig, to enhance cleanliness

Improve and merge types that do not require hooks

Introducing the hook type prctl

These patches is based on https://github.com/backslashxx/KernelSU/issues/5

b56448a929 kernel: Modify and adjust KernelSU Kconfig (#538)
1. List KSU as a "KernelSU" menu
2. Overlayfs[1] may be disabled for some early kernels(4.4.y), so
choosing depends on OVERLAY_FS here is useless.
3. KSU_DEBUG is a bool option, it is not a module, fixed from tristate
to bool.
4. Adjust the config order

432eb318ac kernel: Kconfig: Remove KPROBES dependancy (#453)
For those who want to Implement KernelSU Manually with KPROBES disabled.

When KPROBES Broken and Still enabled, this will causing Loop at splash
logo even Already Manually Imported because this
842c0b674f/kernel/ksu.c (L57).
And when KPROBES is disabled, KSU also will not compiled (I Know it'll
still build if obj-y is set for KSU, but it's better to remove, who
knows if someone set as obj-$(CONFIG_KSU)).
