Month: 2025-10 — KernelSU monthly summary. Key features delivered: Stability improvement for Cgroup PID writes by removing trailing newline when writing a PID to a cgroup node. Major bugs fixed: Resolved issue #2804 by ensuring no newline is written to the cgroup node (commit 1364710021ee7fa25785526d1ef335f3a4d6ddc0). Overall impact: Higher reliability of PID management in cgroups across devices, reducing hangs and kernel-hook triggers. Technologies/skills demonstrated: Rust-based low-level IO handling, Linux cgroup interfacing, precise, minimal patching and commit discipline in tiann/KernelSU.

September 2025 (tiann/KernelSU): Three focused updates delivering stability, guidance, and architecture readiness. Key changes: 1) Isolated process unmount handling for zygote forks: refactored user ID checks, renamed is_unsupported_uid to is_unsupported_app_uid and is_appuid to is_non_appuid, and improved unmount logic to reduce crashes and ensure consistent behavior. Commit 4d3560b12bec5f238fe11f908a246f0ac97e9c27. 2) Shizuku service template compatibility disclaimer: updated the template description to indicate that Shizuku modules may not work with this template, improving user guidance. Commit 78e3ec18748acdc5427c4b981342b8296860b895. 3) Resetprop binary update: updated resetprop binary for aarch64 and x86_64. Binary contents differ, indicating a binary replacement/update with no visible code changes in diff. Commit 66d1188790b0f3dbf6d35246fb49e2f54dbce08d. All changes committed to tiann/KernelSU.
