SELinux is preventing /sbin/dhclient from read, write access on the file /tmp/ffiEg7Nhe (deleted).

*****  Plugin catchall (50.5 confidence) suggests  ***************************

If you believe that dhclient should be allowed read write access on the ffiEg7Nhe (deleted) file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep dhclient /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

*****  Plugin leaks (50.5 confidence) suggests  ******************************

If you want to ignore dhclient trying to read write access the ffiEg7Nhe (deleted) file, because you believe it should not need this access.
Then you should report this as a bug.  
You can generate a local policy module to dontaudit this access.
# grep /sbin/dhclient /var/log/audit/audit.log | audit2allow -D -M mypol
# semodule -i mypol.pp

Comment 1 Miroslav Grepl 2011-09-20 11:50:41 UTC
Looks like NM is leaking to dhclient

Comment 2 Daniel Walsh 2011-09-20 15:32:23 UTC
One hint on this could be a bash redirection could cause this type of problem.

Comment 3 Fedora End Of Life 2012-08-07 16:04:51 UTC
This message is a notice that Fedora 15 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 15. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. At this time, all open bugs with a Fedora 'version'
of '15' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that
we were unable to fix it before Fedora 15 reached end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged to click on
"Clone This Bug" (top right of this page) and open it against that
version of Fedora.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

The process we are following is described here:
