1105 fails to boot....
by Tom London
Running strict/enforcing, latest rawhide:
After installing latest packages, relabeling /etc, /bin, /lib, ....
and rebooting, the system produces lots of udev type errors
(cannot remove /dev/.udev_tdb/classSTUFF) and hangs
on 'adding hardware'
Boots (with messages) in permissive mode.
Here are the 'early' AVCs:

New policy for DCC
by David Hampton
This is a new strict policy for the DCC spam filter. It is based on the
selinux-policy-strict-sources-1.23.2-1 fedora RPM. This policy requires
the definition of dcc reserved ports that were in the net_contexts diff
I sent last Wednesday. Please let me know if there are any problems
with or changes needed to this policy.

Experiences with selinux enabled targetted on Fedora Core 3
by Richard E Miles
In order to become more familiar with the selinux capabilities I did the
following:
Started selinux in permissive mode for targetted. I recieved warnings for the
following services:
portmap, ntpd, and ntpdate.
I then ran fixfiles check. After it ran for quite some time. It did not
report any problems.
So I enabled targetted and rebooted. I then received error warnings for the
same services. The following relevent messages from dmesg follow:
<snip>

Obviously something is amiss. I do not know how to correct these messages for
the services. Does anyone know how the fix this delemma? If not should I
bugzilla it?

Tweaks to the amavis policy
by David Hampton
I've added support to the (unused) amavis policy to allow interaction
with additional mail filters, and added a new type specifically for
quarantined spam and viruses. I also tweaked the network access to
limit ports that can be used by amavisd. I'd appreciate any feedback on
these changes or tips on how to write better policies. Thanks.
David
P.S. These diffs are based on the files from the selinux-policy-strict-
sources-1.22.1-2 rpm.

Tweaks to the clamav policy
by David Hampton
I've added support to the (unused) clamav policy to allow listening for
service requests on a TCP socket, and for interacting with amavis. I
also made some tweaks that tighten up the network access allowed by
freshclam, split the freshclam and spamd log files into two different
types, and make the clamd control socket a unique type. Thanks.
David

hello all, I just joined the list
by nanocurie
Hello all,
I just joined the list. I just downloaded and installed FC3, and
noticed that it had SE-Linux installed by default. I thought okay, so the
NSA now can/will take control of my secure computers. Good, if there's
anyone I'd want controlling them other than I. Then I saw the post about
setools, and saw how they can be used in an enterprise environment. Reminds
me of Active Directory. Cool. This is probably better.
Just kidding bigbrother.
I look forward to learning with you all about SElinux
