+++ This bug was initially created as a clone of Bug #209379 +++

Description of problem:

This problem was discussed in the LSPP conference call and on the
selinux and lspp mailing lists so I'm filing the bugzilla for
tracking purposes.  The issue was raised by Stephen Smalley and
according to Stephen, xinetd will run a service with different a
TE context that the service should have.
See:
https://www.redhat.com/archives/redhat-lspp/2006-October/msg00013.html

Version-Release number of selected component (if applicable):
I believe this is with Rawhide and perhaps FC6 and RHEL5.

To clarify, if xinetd simply runs the service in the peer context, then
the TE domain of the service won't be what we expect it to be, e.g.
instead of running gssftp (/usr/kerberos/sbin/ftpd) in ftpd_t, it would
end up running in the peer's domain (e.g. unconfined_t under targeted,
user_t under strict, or if we had a distinct domain for the ftp client,
whatever domain it would run in).

Looking back, I first raised this issue on redhat-lspp Sep 29 2005 (yes
2005) in response to earlier discussion of the xinetd patch, but
unfortunately lost track of it and didn't remember when the xinetd patch
finally resurfaced this year.  Sorry.

xinetd can ask the kernel what context it would normally run the service
in by default via security_compute_create(), and can adjust the MLS
component based on the peer context.
