Universal Android 15/16 Pseudo-Terminal (/dev/pts) & SELinux Permission Fixer

Magisk & KernelSU module designed to resolve pseudo-terminal allocation failures (/dev/pts/0 TTY unavailable) and SELinux denial rules on Android 15 & 16 (AOSP & Custom ROMs).

---

🔍 Technical Root Cause

Android 15+ mounts /dev/pts (pseudo-terminal slave) with restricted permissions (mode=600). This prevents external terminal applications, debugging binaries, and background root utilities from allocating pseudo-terminal file descriptors.

---

🛠 Fix Mechanism

This module automatically applies runtime mount re-permissions and SELinux policy rules during boot:

chmod 666 /dev/ptmx
mount -o remount,gid=5,mode=666,ptmxmode=0666 /dev/pts
chmod 666 /dev/pts/*

SELinux Policy Injections:

• allow untrusted_app devpts chr_file { read write open ioctl getattr }
• allow magisk devpts chr_file { read write open ioctl getattr }
