+SPECIFIC POLICY FILE INFORMATION
+
+mac_permissions.xml:
+ ABOUT:
+ The mac_permissions.xml file is used for controlling the mmac solutions
+ as well as mapping a public base16 signing key with an arbitrary seinfo
+ string. Details of the files contents can be found in a comment at the
+ top of that file. The seinfo string, previously mentioned, is the same string
+ that is referenced in seapp_contexts.
+
+ This file can be replaced through BOARD_SEPOLICY_REPLACE containing the
+ value "mac_permissions.xml", however, appending (UNION) does NOT exist
+ and will cause a build time failure. It is important to note the final
+ processed version of this file is stripped of comments and whitespace.
+ This is to preserve space on the system.img. If one wishes to view it in
+ a more human friendly format, the "tidy" or "xmllint" command will assist
+ you.
+
+ TOOLING:
+ insertkeys.py
+ Is a helper script for mapping arbitrary tags in the signature stanzas of
+ mac_permissions.xml to public keys found in pem files. This script takes
+ a mac_permissions.xml file and configuration file in order to operate.
+ Details of the configuration file (keys.conf) can be found in the subsection
+ keys.conf. This script is also responsible for stipping the comments and
+ whitespace from the xml file.
+
+ keys.conf
+ The keys.conf file is used for controlling the mapping of "tags" found in
+ the mac_permissions.xml signature stanzas with actual public keys found in
+ pem files. The configuration file can be used in BOARD_SEPOLICY_UNION and
+ BOARD_SEPOLICY_REPLACE variables and is processed via m4.
+
+ The script allows for mapping any string contained in TARGET_BUILD_VARIANT
+ with specific path to a pem file. Typically TARGET_BUILD_VARIANT is either
+ user, eng or userdebug. Additionally, one can specify "ALL" to map a path to
+ any string specified in TARGET_BUILD_VARIANT. All tags are matched verbatim
+ and all options are matched lowercase. The options are "tolowered" automatically
+ for the user, it is convention to specify tags and options in all uppercase
+ and tags start with @.
+
+ NOTE: The pem files are base64 encoded and PackageManagerService, mac_permissions.xml
+ and setool all use base16 encodings.

- Sample signer stanza for install policy
-
- Rules:
- * A signature is a hex encoded X.509 certificate and is required for each signer tag.
- * A <signer signature="" > element may have multiple child elements:
- allow-permission : produces a set of maximal allowed permissions (whitelist).
- deny-permission : produces a blacklist of permissions to deny.
- allow-all : a wildcard tag that will allow every permission requested.
- package : a complex tag which itself defines allow, deny, and wildcard sub elements for
- a specific package name protected by the signature
- * Zero or more global <package name=""> tags are allowed. These tags allow a policy
- to be set outside any signature for specific package names.
- * Unknown tags at any level are skipped.
- * Zero or more signer tags are allowed.
- * Zero or more package tags are allowed per signer tag.
- * A <package name=""> tag may not contain another <package name=""> tag. If found, it's skipped.
- * A <default> tag is allowed that can contain install policy for all apps not signed with a
- previously listed cert and not having a per package global policy.
- * When multiple sub elements appear for a tag the following logic is used to
- ultimately determine the type of enforcement:
- ** A blacklist is used if at least one deny-permission tag is found
- ** A whitelist is used if not a blacklist and at least one allow-permission tag is found
- ** A wildcard (accept all permission) policy is used if not a blacklist and not a whitelist
- and at least one allow-all tag is present.
- ** If a <package name=""> sub element is found then that sub element's policy is used
- according to the above logic and overrides any signature global policy type.
- ** In order for a policy stanza to be enforced at least one of the above situations must
- apply. Meaning, empty signer, default or package tags will not be accepted.
- * Each signer/default/global package tag is allowed to contain one <seinfo value=""/> tag.
- This tag represents additional info that each app can use in setting a SELinux security
- context on the eventual process. Any <seinfo value=""/> tag found as a child of a
- <package name=""> tag which is protected (sub element of signer or the default tag) is
- ignored. It's possible that multiple seinfo tags are relevant for one app. In the event
- that this happens, the seinfo tag that will be applied is the one for which the corresponding
- policy stanza is used in the policy decision.
- * Strict enforcing of any xml stanza is not enforced in most cases. This mainly applies to
- duplicate tags which are allowed. In the event that a tag already exists, the original
- tag is replaced.
- * There are also no checks on the validity of permission names. Although valid android
- permissions are expected, nothing prevents unknowns.
- * Enforcement decisions:
- - All signatures used to sign an app are checked for policy according to signer tags.
- Only one of the signature policies has to pass however.
- - In the event that none of the signature policies pass, or none even match, then
- a global package policy is sought. If found, this policy mediates the install.
- - The default tag is consulted last if needed.
- - A local package policy always overrides any parent policy.
- - If none of the cases apply then the app is denied.
-
-
- Example global package policy
- <package name="com.foo.com">
- <allow-permission name="android.permission.INTERNET" />
- <allow-permission name="android.permission.WRITE_EXTERNAL_STORAGE" />
- <allow-permission name="android.permission.ACCESS_NETWORK_STATE" />
- </package>
-
- Sample stanzas are given below based on the AOSP developer keys.
