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.

* ksud: fix cargo check

* manager: Fixed an issue where the KSUD release and user-mode scanning switch failed to function correctly.

kernel: try introduce like susfs's method to fix prctl delay

* seccomp: allow reboot

* use u32

* update clang-format

* 4 spaces save the world

* ksud: Fix build on macOS

* manager: bump minimal supported kernel.

- When get_hook_type is empty, display “Unknown”.


* Fix ksud build (#2841)

* try fix ksud

* fix for macos

* remove any

* try fix allowlist

* bring lsm hook back

* fix: a lot again

* Fix ksud build, take 4 (#2846)

Remove init_driver_fd function for non-linux/android targets

* manager: Return to the native method via KSUd installation

* Merge with susfs-mian format
