Review request for mesos and Mesos Reviewbot.

Bugs: MESOS-7363

Repository: mesos


It is possible for a malicious client to send
libprocess SUBSCRIBE requests that will trigger the
!frameworks.principals.contains(...) CHECK. This can happen
if the client sends a subscribe with a framework ID, then a
second subscribe with a different framework ID but the same
UPID. The invariant in the master is that a UPID uniquely
identifies a given framework. This is violated if we allow
multiple frameworks with the same UPID.


  src/master/master.cpp e547d2c410471f42bfeaae40a8b57ca30033e54f 


Testing (updated)

make check (Fedora 25). Internal fuzzer run.
