prebuilts/api/33.0/private/seapp_contexts

# The entries in this file define how security contexts for apps are determined.
# Each entry lists input selectors, used to match the app, and outputs which are
# used to determine the security contexts for matching apps.
#
# Input selectors:
#       isSystemServer (boolean)
#       isEphemeralApp (boolean)
#       user (string)
#       seinfo (string)
#       name (string)
#       isPrivApp (boolean)
#       minTargetSdkVersion (unsigned integer)
#       fromRunAs (boolean)
#
# All specified input selectors in an entry must match (i.e. logical AND).
# An unspecified string or boolean selector with no default will match any
# value.
# A user, or name string selector that ends in * will perform a prefix
# match.
# String matching is case-insensitive.
# See external/selinux/libselinux/src/android/android_platform.c,
# seapp_context_lookup().
#
# isSystemServer=true only matches the system server.
# An unspecified isSystemServer defaults to false.
# isEphemeralApp=true will match apps marked by PackageManager as Ephemeral
# user=_app will match any regular app process.
# user=_isolated will match any isolated service process.
# user=_sdksandbox will match sdk sandbox process for an app.
# Other values of user are matched against the name associated with the process
# UID.
# seinfo= matches aginst the seinfo tag for the app, determined from
# mac_permissions.xml files.
# The ':' character is reserved and may not be used in seinfo.
# name= matches against the package name of the app.
# isPrivApp=true will only match for applications preinstalled in
#       /system/priv-app.
# minTargetSdkVersion will match applications with a targetSdkVersion
#       greater than or equal to the specified value. If unspecified,
#       it has a default value of 0.
# fromRunAs=true means the process being labeled is started by run-as. Default
# is false.
#
# Precedence: entries are compared using the following rules, in the order shown
# (see external/selinux/libselinux/src/android/android_platform.c,
# seapp_context_cmp()).
#       (1) isSystemServer=true before isSystemServer=false.
#       (2) Specified isEphemeralApp= before unspecified isEphemeralApp=
#             boolean.
#       (3) Specified user= string before unspecified user= string;
#             more specific user= string before less specific user= string.
#       (4) Specified seinfo= string before unspecified seinfo= string.
#       (5) Specified name= string before unspecified name= string;
#             more specific name= string before less specific name= string.
#       (6) Specified isPrivApp= before unspecified isPrivApp= boolean.
#       (7) Higher value of minTargetSdkVersion= before lower value of
#              minTargetSdkVersion= integer. Note that minTargetSdkVersion=
#              defaults to 0 if unspecified.
#       (8) fromRunAs=true before fromRunAs=false.
# (A fixed selector is more specific than a prefix, i.e. ending in *, and a
# longer prefix is more specific than a shorter prefix.)
# Apps are checked against entries in precedence order until the first match,
# regardless of their order in this file.
#
# Duplicate entries, i.e. with identical input selectors, are not allowed.
#
# Outputs:
#       domain (string)
#       type (string)
#       levelFrom (string; one of none, all, app, or user)
#       level (string)
#
# domain= determines the label to be used for the app process; entries
# without domain= are ignored for this purpose.
# type= specifies the label to be used for the app data directory; entries
# without type= are ignored for this purpose. The label specified must
# have the app_data_file_type attribute.
# levelFrom and level are used to determine the level (sensitivity + categories)
# for MLS/MCS.
# levelFrom=none omits the level.
# levelFrom=app determines the level from the process UID.
# levelFrom=user determines the level from the user ID.
# levelFrom=all determines the level from both UID and user ID.
#
# levelFrom=user is only supported for _app or _isolated UIDs.
# levelFrom=app or levelFrom=all is only supported for _app UIDs.
# level may be used to specify a fixed level for any UID.
#
# For backwards compatibility levelFromUid=true is equivalent to levelFrom=app
# and levelFromUid=false is equivalent to levelFrom=none.
#
#
# Neverallow Assertions
# Additional compile time assertion checks for the rules in this file can be
# added as well. The assertion
# rules are lines beginning with the keyword neverallow. Full support for PCRE
# regular expressions exists on all input and output selectors. Neverallow
# rules are never output to the built seapp_contexts file. Like all keywords,
# neverallows are case-insensitive. A neverallow is asserted when all key value
# inputs are matched on a key value rule line.
