*** This bug is a security vulnerability ***

Public security bug reported:

It was discovered that Linux incorrectly accounted the number of in-
flight fds over a unix domain socket to the original opener of the file-
descriptor. This allows another process to arbitrary deplete the
original file-openers resource limit for the maximum of open files.
Instead the sending processes and its struct cred should be credited.
