Currently, permissions for ctl. property apply to each action verb, so
if a domain has permissions for controlling service 'foo', then it can
start, stop, and restart foo.
This change implements finer grainer permissions such that permission
can be given to strictly start a given service, but not stop or
restart it. This new permission scheme is mandatory for the new
control functions, sigstop_on, sigstop_off, interface_start,
interface_stop, interface_restart.
Bug: 78511553
Test: see appropriate successes and failures based on permissions

System properties can be abused to get around Treble requirements of
having a clean system/vendor split. This CL seeks to prevent that by
neverallowing coredomain from writing vendor properties.

to workaround some VTS VtsKernelLtp failures introduced by
change on vfs_iter_write here:
abbb65899a%5E%21/#F3
for discussion please check threads here:
https://www.mail-archive.com/seandroid-list@tycho.nsa.gov/msg03348.html
Sandeep suggest to re-order the events in that thread,
that should be the right solution,
this change is only a tempory workaround before that change.
