PEKKA Chang fb109b5eec binder: fix missing prototype for zap_page_range_single deps.c implements zap_page_range_single() as a runtime compat shim (resolved via kallsyms_lookup_name), but deps.h never declared its prototype, and binder_alloc.c did not include deps.h. Newer compilers (Clang, building with -std=gnu11 and later defaults) treat an implicit function declaration as a hard error rather than a warning, so the module fails to build: binder_alloc.c:1029:3: error: call to undeclared function 'zap_page_range_single'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration] Declare the prototype in deps.h and include it from binder_alloc.c. Verified the module builds and links cleanly (binder_linux.ko) against kernel 7.1.1 with the fix applied; previously failed with the error above.		2026-06-21 15:20:27 +08:00

Anbox Kernel Module

This repository contains the kernel module necessary to run the Anbox Android container runtime. They're split out of the original Anbox repository to make packaging in various Linux distributions easier.

Install Instruction

You need to have dkms and linux-headers on your system. You can install them by sudo apt install dkms or sudo yum install dkms (dkms is available in epel repo for CentOS).

Package name for linux-headers varies on different distributions, e.g. linux-headers-generic (Ubuntu), linux-headers-amd64 (Debian), kernel-devel (CentOS, Fedora), kernel-default-devel (openSUSE).

You can either run ./INSTALL.sh script to automate the installation steps or follow them manually below:

First install the configuration files:

 sudo cp anbox.conf /etc/modules-load.d/
 sudo cp 99-anbox.rules /lib/udev/rules.d/

Then copy the module sources to /usr/src/:

 sudo cp -rT binder /usr/src/anbox-binder-1

Finally use dkms to build and install:
```
 sudo dkms install anbox-binder/1
```

You can verify by loading these module and checking the created device:

 sudo modprobe binder_linux
 lsmod | grep -e binder_linux
 ls -alh /dev/binder

You are expected to see output like:

binder_linux          114688  0
crw-rw-rw- 1 root root 511,  0 Jun 19 16:30 /dev/binder

Uninstall Instructions

ou can either run ./UNINSTALL.sh script to automate the installation steps or follow them manually below:

First use dkms to remove the module:
```
 sudo dkms remove anbox-binder/1
```
Then remove the module sources from /usr/src/:
```
 sudo rm -rf /usr/src/anbox-binder-1
```

Finally remove the configuration files:

 sudo rm -f /etc/modules-load.d/anbox.conf
 sudo rm -f /lib/udev/rules.d/99-anbox.rules

You must then restart your device. You can then verify module was removed by trying to load the module and checking the created device:

 sudo modprobe binder_linux
 lsmod | grep -e binder_linux
 ls -alh /dev/binder

You are expected to see output like:

modprobe: FATAL: Module binder_linux not found in directory /lib/modules/6.0.2-76060002-generic
ls: cannot access '/dev/binder': No such file or directory

Packaging:

Debian/Ubuntu:

sudo apt-get install devscripts dh-dkms -y 
git log --pretty=" -%an<%ae>:%aI - %s" > ./debian/changelog
debuild -i -us -uc -b 
ls -lrt ../anbox-modules-dkms_*.deb
