1This directory contains a number of tools related to policy, some of
2which are used in building and validating the policy and others are
3available for help in auditing and analyzing policy.  The tools are
4described further below.
5
6checkfc
7   A utility for checking the validity of a file_contexts or a
8   property_contexts configuration file.  Used as part of the policy
9   build to validate both files.  Requires the sepolicy file as an
10   argument in order to check the validity of the security contexts
11   in the file_contexts or property_contexts file.
12
13   Usage1:
14   checkfc sepolicy file_contexts
15   checkfc -p sepolicy property_contexts
16
17   Also used to compare two file_contexts or file_contexts.bin files.
18   Displays one of subset, equal, superset, or incomparable.
19
20   Usage2:
21   checkfc -c file_contexts1 file_contexts2
22
23   Example:
24   $ checkfc -c out/target/product/shamu/system/etc/general_file_contexts out/target/product/shamu/root/file_contexts.bin
25   subset
26
27checkseapp
28    A utility for merging together the main seapp_contexts
29    configuration and the device-specific one, and simultaneously
30    checking the validity of the configurations. Used as part of the
31    policy build process to merge and validate the configuration.
32
33    Usage:
34    checkseapp -p sepolicy input_seapp_contexts0 [input_seapp_contexts1...] -o seapp_contexts
35
36insertkeys.py
37    A helper script for mapping tags in the signature stanzas of
38    mac_permissions.xml to public keys found in pem files.  This
39    script is described further in the top-level sepolicy/README.
40
41post_process_mac_perms
42    A tool to help modify an existing mac_permissions.xml with additional app
43    certs not already found in that policy. This becomes useful when a directory
44    containing apps is searched and the certs from those apps are added to the
45    policy not already explicitly listed.
46
47    Usage:
48    post_process_mac_perms [-h] -s SEINFO -d DIR -f POLICY
49
50      -s SEINFO, --seinfo SEINFO  seinfo tag for each generated stanza
51      -d DIR, --dir DIR           Directory to search for apks
52      -f POLICY, --file POLICY    mac_permissions.xml policy file
53
54sepolicy-check
55    A tool for auditing a sepolicy file for any allow rule that grants
56    a given permission.
57
58    Usage:
59    sepolicy-check -s <domain> -t <type> -c <class> -p <permission> -P out/target/product/<board>/root/sepolicy
60
61sepolicy-analyze
62    A tool for performing various kinds of analysis on a sepolicy
63    file.
