Is it also generally useful in practice? Thoughts?
The locking is wrong. At the moment the entire kernel assumes that a
process uid is not changed by anyone else. After you've implemented uid
locking/refcounting for tasks you can add the syscall but until then its
not a good idea. I don't think its a good idea anyway - selinux can do
far more useful things.
Indeed. "Also it's not obvious that locking can be done right (or that
anybody cares). "
We can ignore it safely. sys_promote is a different approach from
selinux. sys_promote is to let sysadmin manually manipulate a running
process,
