In case a setuid or setgid binary is mislabeled with a generic context,
either via a policy mistake or a move by the distribution package,
executing it will be checked by the file permission execute_no_trans on
the generic file context (e.g. bin_t). The setuid(2)/setgid(2) syscall
within will then be checked against the unchanged caller process
context, which might have been granted the capability permission setuid/
setgid to initially drop privileges. To avoid that scenario split the
execute_no_trans permission in case of a setuid/setgid binary into a new
permission execute_sxid_no_trans.
For backward compatibility this behavior is contained in a new policy
capability.

Adding the refpolicy list to this thread as their opinion seems
particularly relevant to this discussion.
FWIW, this looks reasonable to me but I would like to hear what others
have to say.

I think this a band-aid to cover up the real problem, which is the mislabeled files.

It's hard to disagree with that, and the kernel is probably the wrong
place to apply a band-aid unless it is the only option left.
