backslashxx ae36e2085c kernel: handle optional backports (#99) 
Cherry pick from https://github.com/backslashxx/KernelSU/commit/8bb9518060b06152b99f11465e20febc45359d3c https://github.com/backslashxx/KernelSU/commit/a4a7db7f40556287bfe53b65e998283c06363dd9

Backporting is cool, but not everyone has the skills for it.
This commit does NOT make it required, but it will allow compiler
to use whats in-kernel if it exists.

The following are backportable:
 - kernel_read / kernel_write
 	< 4.14, backport chain, tested on 4.9
 	https://github.com/torvalds/linux/commit/e13ec939e96b13e664bb6cee361cc976a0ee621a
	https://github.com/torvalds/linux/commit/bdd1d2d3d251c65b74ac4493e08db18971c09240

	https://github.com/torvalds/linux/commit/ac452acae1caa1a451142a30b4e1ea09cfac4410

 - strncpy_from_user_nofault
 	for 5.4, apply: https://github.com/torvalds/linux/commit/bd88bb5d4007949be7154deae7cef7173c751a95
 	for 4.x, apply: https://github.com/xiaomi-sdm678/android_kernel_xiaomi_mojito/commit/424e21f3b01ddaeb86cef7efd3f519a7e342fb67
 	for any failures, just SKIP THIS or check dependency chain of, https://github.com/gregkh/linux/commit/3d7081822f7f9eab867d9bcc8fd635208ec438e0
 		this got backported to v4.4.236, v4.9.236, v4.14.197, v4.19.144

- hint, `curl $url.patch | git am`

5ec1cff 87fc6b2784 kernel: clear securebits 
fix adb shell cannot escape to root after https://github.com/tiann/KernelSU/pull/2381
 2025-01-27 20:05:54 +06:00
Wang Han a05b790da6 Avoid unnecessarily overriding capabilities (#2381) 
Previously all capabilities were overridden with 0xffffffffffffffff,
which is
not what normal processes have. This causes PR_CAPBSET_DROP prctl
fail because it is dropping invalid caps. Fix it.

This fixes
https://gitlab.com/kalilinux/nethunter/apps/kali-nethunter-app/-/issues/378.

SsageParuders b18c39e911 Improve seccomp disable && Add locking to protect cred modifications in escape_to_root (#2320) 
- When disabling Seccomp, ensure that current->sighand->siglock is held
during the operation.
- Locking to ensure safe access and modification of the `cred` structure
within the `escape_to_root` function.

---

I think this issue described in #2236 may have been caused by concurrent
read-write access without proper locking.

ExtremeXT 72739facc8 kernel: expose allowlist workaround as Kconfig option 
Useful for situations where the SU allowlist is not kept after a reboot.
As per upstream this is only used for < 4.10 and Huawei HiSilicon devices.
but theres user reports having issues even on 4.14/4.19 samsung kernels.
Expose this option so users affected can opt-in.

backslashxx 36fb6085ef kernel: require path_umount backporting 
Most kernel builders have to touch their kernel source code anyway so
we might as well tell them to backport path_umount to achieve some sort
of feature parity.

This enforces a path_umount backport, not a suggestion.
Its a requirement from now on.

You will backport path_umount and you will like it.

Huy Minh 3acb13df65 kernel: Relax dentry_path_raw compare in core_hook (#2041) 
On Android-x86 (or BlissOS) it initialize Android by using switch_root
or chroot, when checking a path with dentry_path_raw() it will show the
whole real path instead of the path that we want.

Relax the checking requirement by using strstr to look for
"/system/packages.list" in the string instead of requiring the path to
be "/system/packages.list"

This fixes #1783
