Subject: [PATCH] Give healthd permission to write sys properties to allow
quick boot from charger mode.
Property being set: sys.boot_from_charger_mode. If healthd attempts to write
this property without the policy changes we get the following audit message:
[ 45.751195] type=1400 audit(1403556447.444:7): avc: denied { write } for pid=99 comm="charger" name="property_service" dev="tmpfs" ino=3229 scontext=u:r:healthd:s0 tcontext=u:object_r:property_socket:s0 tclass=sock_file permissive=0
These changes are needed to support the following system/core commit:
faster booting from charger mode
