* use snprintf

* refactor: new supercall impl

- Import the sukisu command

* disable seccomp for supercall users

* kernel: fmt clear

* kernel: Enable macro protection for sulog

* 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: fix spin lock mutual

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.

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

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`

c0066b68f5 kernel: support the case that init_task.mnt_ns != zygote.mnt_ns(WSA) (#698)
Basic support for the case that init_task.mnt_ns != zygote.mnt_ns(WSA),
just copy nsproxy and fs pointers for solve #276.

Note the copy in `apk_sign.c` is not required but suggested for
secure(ensure the checked mnt_ns is what ns android running, not created
by user, although many distributions does not have user ns.).

Tested with latest release on Win10 19045.3086(with WSAPatch).

Further review required for:
- [x] Security of this operation (without locking).
- [x] The impact of these modifications on other Android distributions.
