Some vendor apps are using platform key for signing.
This moves them to untrusted_app domain when the system partition is
switched to a Generic System Image (GSI), because the value of
platform's seinfo in /system/etc/selinux/plat_mac_permissions.xml
has been changed.
Duplicating the device-specific platform seinfo into
/vendor/etc/selinux/vendor_mac_permissions.xml to make it
self-contained within the vendor partition.
Bug: 157141777
Test: boot the device with a GSI, then `adb shell ps -eZ | grep qtidata`
Test: ./build/make/tools/releasetools/sign_target_files_apks \
--default_key_mappings path/to/keydir \
-o out/dist/<lunch>-target_files-*.zip \
signed-tardis-target_files.zip and checks the platform seinfo in
/vendor/etc/selinux/vendor_mac_permissions.xml is replaced.

|
* A signature is a hex encoded X.509 certificate or a tag defined in
|
|
keys.conf and is required for each signer tag. The signature can
|
|
either appear as a set of attached cert child tags or as an attribute.
|
|
* A signer tag must contain a seinfo tag XOR multiple package stanzas.
|
|
* Each signer/package tag is allowed to contain one seinfo tag. This tag
|
|
represents additional info that each app can use in setting a SELinux security
|
|
context on the eventual process as well as the apps data directory.
|
|
* seinfo assignments are made according to the following rules:
|
|
- Stanzas with package name refinements will be checked first.
|
|
- Stanzas w/o package name refinements will be checked second.
|
|
- The "default" seinfo label is automatically applied.
|
|
|
|
* valid stanzas can take one of the following forms:
|
|
|
|
// single cert protecting seinfo
|
|
<signer signature="@PLATFORM" >
|
|
<seinfo value="platform" />
|
|
</signer>
|
|
|
|
// multiple certs protecting seinfo (all contained certs must match)
|
|
<signer>
|
|
<cert signature="@PLATFORM1"/>
|
|
<cert signature="@PLATFORM2"/>
|
|
<seinfo value="platform" />
|
|
</signer>
|
|
|
|
// single cert protecting explicitly named app
|
|
<signer signature="@PLATFORM" >
|
|
<package name="com.android.foo">
|
|
<seinfo value="bar" />
|
|
</package>
|
|
</signer>
|
|
|
|
// multiple certs protecting explicitly named app (all certs must match)
|
|
<signer>
|
|
<cert signature="@PLATFORM1"/>
|
|
<cert signature="@PLATFORM2"/>
|
|
<package name="com.android.foo">
|
|
<seinfo value="bar" />
