This script will build the SELinux policy for multiple targets in parallel. To use it, run: ./build_policies.sh <Android root directory> <output directory> [specific targets to build] If you do not pass any individual targets, it will build all targets it can find. It will print out the list of failing targets. You can open up the corresponding log file in the output directory to see the exact errors. This script is still a work in progress. It currently cannot discover all build targets (it misses ones "lunch" does not list). Bug: 33463570 Test: Ran script to build multiple targets with and without failures.

This directory contains a number of tools related to policy, some of
|
|
which are used in building and validating the policy and others are
|
|
available for help in auditing and analyzing policy. The tools are
|
|
described further below.
|
|
|
|
build_policies.sh
|
|
A tool to build SELinux policy for multiple targets in parallel.
|
|
This is useful for quickly testing a new test or neverallow rule
|
|
on multiple targets.
|
|
|
|
Usage:
|
|
./build_policies.sh ~/android/master ~/tmp/build_policies
|
|
./build_policies.sh ~/android/master ~/tmp/build_policies sailfish-eng walleye-eng
|
|
|
|
checkfc
|
|
A utility for checking the validity of a file_contexts or a
|
|
property_contexts configuration file. Used as part of the policy
|
|
build to validate both files. Requires the sepolicy file as an
|
|
argument in order to check the validity of the security contexts
|
|
in the file_contexts or property_contexts file.
|
|
|
|
Usage1:
|
|
checkfc sepolicy file_contexts
|
|
checkfc -p sepolicy property_contexts
|
|
|
|
Also used to compare two file_contexts or file_contexts.bin files.
|
|
Displays one of subset, equal, superset, or incomparable.
|
|
|
|
Usage2:
|
|
checkfc -c file_contexts1 file_contexts2
|
|
|
|
Example:
|
|
$ checkfc -c out/target/product/shamu/system/etc/general_file_contexts out/target/product/shamu/root/file_contexts.bin
|
|
subset
|
|
|
|
checkseapp
|
|
A utility for merging together the main seapp_contexts
|
|
configuration and the device-specific one, and simultaneously
|
|
checking the validity of the configurations. Used as part of the
|
|
policy build process to merge and validate the configuration.
|
|
|
|
Usage:
|
|
checkseapp -p sepolicy input_seapp_contexts0 [input_seapp_contexts1...] -o seapp_contexts
|
|
|
|
insertkeys.py
|
|
A helper script for mapping tags in the signature stanzas of
|
|
mac_permissions.xml to public keys found in pem files. This
|
|
script is described further in the top-level sepolicy/README.
|
|
|
|
post_process_mac_perms
|
|
A tool to help modify an existing mac_permissions.xml with additional app
|
|
certs not already found in that policy. This becomes useful when a directory
|
|
containing apps is searched and the certs from those apps are added to the
|
|
policy not already explicitly listed.
|
|
|
|
Usage:
|
|
post_process_mac_perms [-h] -s SEINFO -d DIR -f POLICY
|
|
|
|
-s SEINFO, --seinfo SEINFO seinfo tag for each generated stanza
|
|
-d DIR, --dir DIR Directory to search for apks
|
|
-f POLICY, --file POLICY mac_permissions.xml policy file
|
|
|
|
sepolicy-check
|
|
A tool for auditing a sepolicy file for any allow rule that grants
|
|
a given permission.
|
|
|
|
Usage:
|
|
sepolicy-check -s <domain> -t <type> -c <class> -p <permission> -P out/target/product/<board>/root/sepolicy
|
|
|
|
sepolicy-analyze
|
|
A tool for performing various kinds of analysis on a sepolicy
|
|
file.
