Something went wrong on our end

Nick Kralevich authoredChrome renderer processes dlopen() a shared library from gmscore. Open and read on app data file is already allowed, but execute isn't, so the dlopen() fails. This is a regression from K, where the dlopen succeeded. Longer term, there's questions about whether this is appropriate behavior for an isolated app. For now, allow the behavior. See the discussion in b/15902433 for details. Addresses the following denial: I/auditd ( 5087): type=1400 audit(0.0:76): avc: denied { execute } for comm="CrRendererMain" path="/data/data/com.google.android.gms/files/libAppDataSearchExt_armeabi_v7a.so" dev="mmcblk0p28" ino=83196 scontext=u:r:isolated_app:s0 tcontext=u:object_r:app_data_file:s0 tclass=file Bug: 15902433 Change-Id: Ie98605d43753be8c31a6fe510ef2dde0bdb52678Nick Kralevich authoredChrome renderer processes dlopen() a shared library from gmscore.

### This file defines the rules for isolated apps. An "isolated
### app" is an APP with UID between AID_ISOLATED_START (99000)
### and AID_ISOLATED_END (99999).
###
### isolated_app includes all the appdomain rules, plus the
### additional following rules:
###
type isolated_app, domain;
app_domain(isolated_app)
net_domain(isolated_app)
# read and write access to app_data_file is already
# granted via app.te. Allow execute.
# Needed to allow dlopen() from Chrome renderer processes.
# See b/15902433 for details.
