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 aa2cbbf.
* 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: fix spin lock mutual

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
* Fix ksud build, take 3
* 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
