1 This fork of Android differs in the following ways: 2 - README.android 3 - All Android.mk and Android.bp files 4 - ALL MODULE_LICENSE_* files 5 - libselinux/include/selinux/android.h 6 - libselinux/src/android/android.c 7 8 All other changes should be upstreamed to selinux as 9 Android no longer carries changes outside of those files. 10 11 The upstream project can be found at: 12 https://github.com/SELinuxProject/selinux 13 14 Thus, since all changes are in separate files, updates merged from 15 upstream should occur with no merge conflicts. 16 17 This fork differs from upstream libselinux in at least the following ways: 18 19 * The Android fork omits compiling many of the src files and specifies 20 custom build configurations. The exact details, are encoded in the 21 Android.bp and Android.mk files. 22 23 * The SELinux policy files are all located in / rather than under 24 /etc/selinux since /etc is not available in Android until /system 25 is mounted and use fixed paths, not dependent on /etc/selinux/config. 26 27 * The kernel policy file (sepolicy in Android, policy.N in Linux) does 28 not include a version suffix since Android does not need to support 29 booting multiple kernels. 30 31 * The policy loading logic does not support automatic downgrading of 32 the kernel policy file to a version known to the kernel, since this 33 requires libsepol on the device and is only needed to support mixing 34 and matching kernels and userspace easily. 35 36 * restorecon functionality, including recursive restorecon, has been 37 been upstreamed as selinux_restorecon(), but there are residual 38 differences between it and selinux_android_restorecon(). 39 40 * Support for seapp_contexts, a new Android-specific SELinux 41 configuration file has been added within android.c. 42
