Neo Zygisk

NeoZygisk is a Zygote injection module implemented using ptrace, which provides Zygisk API support for APatch/KernelSU and serves as a replacement of Magisk’s built-in Zygisk.

Requirements

General

• No multiple root implementation installed

APatch

• Minimal APatch version: 10762

KernelSU

• Minimal KernelSU version: 10940
• Minimal KernelSU Manager (ksud) version: 11424
• Kernel has full SELinux patch support

Magisk

• Minimal version: 26402
• Built-in Zygisk turned off

Design goals

1. NeoZygisk always synchronises with the Magisk built-in Zygisk API design, which are copied into the source folder injector.
2. NeoZygisk aims to provide a minimalist implementation of Zygisk API; unnecessary features are thus not considered.
3. NeoZygisk guarantees to clean its injection trace inside applications processes once all Zygisk modules are unloaded.
4. NeoZygisk helps to hide the traces of root solutions through its design of DenyList, as explained below.

DenyList

Current root solutions of Android are implemented in a systmeless way, meaning that they overlay the filesystems of the device by mounting instead of overwriting the actual file contents. DenyList is designed to help the mounting trace hiding, which provides the following controls over how mount namespaces are defined for app processes.

1. For applications granted with root privilege, both root solutions mount points and modules mount points are present in their mount namespaces.
2. [APatch/KSU only] For applications without root privilege and not on the DenyList, only modules mount points are present in their mount namespaces. As an example, this is the ideal configuration for applying font customization modules to their target applications. Note: this is not implemented for Magisk, which needs root mounting points to receive root permission requests.
3. For applications on the DenyList, their root privilege will be dropped even granted intentionally. A clean mount namespace will be provided for them to hide the traces of root solutions.
