Build the selinux_version file. · 8b7545bf

Robert Craig authored 11 years ago


The selinux_version file is used to perform policy
versioning checks by libselinux and SELinuxMMAC. When
loading policy a check is first performed to determine
if the policy out in /data/security/current should be
used to override the base policy shipped with the device.
The selinux_version file is used to make that choice. The
contents of the file simply contains the BUILD_FINGERPRINT
that the policy was built against. A simple string comparison
is then performed by libselinux and SELinuxMMAC.
