Re: Possible bug..
by Mark Evers
Well, after alot of trying i did a fixfiles relabel and right after that a touch /.autorelabel and rebooted the machine, and dovecot works again.
I still don't know what went wrong, but it works again.

Subject: Possible bug..
First of all, i'm hoping i'm posting this the right way, but i've tried everything that i know
I'm having problems with Dovecot, and i've asked for help in #fedore on freenode.net, without success and they adviced me to post it here.
This is the error i get in /var/log/audit/audit.log when i start dovecot using webmin
type=AVC msg=audit(1134174789.681:11): avc: denied { read } for pid=2908 comm="dovecot" name="dovecot" dev=dm-0 ino=67858 scontext=system_u:system_r:dovecot_t tcontext=system_u:object_r:bin_t tclass=dir

On my screen i get "Starting Dovecot Imap: Fatal: unlink_directory() failed for /var/run/dovecot-login: Permission denied"
When i try to start dovecot using "service dovecot start" or /etc/rc.d/init.d/dovecot start i get "Starting Dovecot Imap: [FAILED]"
I've allready tried a fixfiles and even a touch /.autorelabel without luck.
The system is fully updated with yum, and removing/adding dovecot doesn't make a difference.
I Hope someone can help.
Thanks

mysqld_disable_trans leaves mysqld running as initrc_t?
by Chuck Anderson
I've disabled SELinux protection of mysqld since it was causing major
performance problems. This broke CGI scripts since httpd_script_t
couldn't connect to the mysql unix domain socket. audit2allow created
these rules which I put into local.te:
allow httpd_sys_script_t var_t:dir getattr;
allow httpd_sys_script_t initrc_t:unix_stream_socket connectto;
allow httpd_t initrc_t:unix_stream_socket connectto;
This fixed the problem. However, is mysqld supposed to be running as
initrc_t instead of unconfined_t when mysqld_disable_trans is set?

Allow apache to send mail?
by Robin Bowes
Hi,
Can anyone tell me how to allow apache (httpd) to send mail, i.e. to use
the smtp port?
I'm trying to enable notifications in Trac and am seeing this in the
audit log:

How do I modify my policy to allow this?

Spamassasin Problem
by W. Scott Wilburn
Hi,
Since upgrading from spamassassin.i386 3.0.4-2.fc4 to
spamassassin.i386 3.0.4-1.fc4, I get avc denied messages:
Nov 20 04:05:44 scooby kernel: audit(1132484744.807:45387): avc: denied
{ search } for pid=25548 comm="spamd" name=".spamassassin" dev=md0
ino=2197675 scontext=root:system_r:spamd_t
tcontext=user_u:object_r:user_home_t tclass=dir
FC4, targeted policy enforcing mode
selinux-policy-targeted-sources.noarch 1.27.1-2.11
Since the problem occurred with a spamassassin update, not selinux, I
assume something in the behavior of spamassassin has changed.
Any help appreciated.

The Second SELinux Symposium features two full days of SELinux-related
tutorials followed by a two-day technical agenda that includes papers,
presentations, and case studies by experts and practitioners with SELinux.
Topics for the symposium include in-depth discussions of the core SELinux
technology, emerging SELinux policy management and development tools,
experiences using SELinux to build secure system solutions, and the status
of SELinux within Linux. New this year is an invitation-only SELinux
developer summit, where the core developers and contributors of SELinux
discuss upcoming technology changes, requirements, and plans.
Papers for the symposium were selected via a community review process, and
include authors from several organizations including IBM, MITRE Corporation,
Pennsylvania State University, Purdue University, Red Hat, Tresys
Technology, Trusted Computer Solutions, University of Illinois, University
of Tulsa, University of Wisconsin, and the U.S. National Security Agency.

Selinux and RPM packaging (trac)
by Nicklas Norling
Hi,
Been looking around for quite some time and have found very little about
how one is
supposed to create rpm packages with selinux content.
Specifically I'm trying to create a rpm package of trac
http://projects.edgewall.com/trac/.
The Wiki there suggests .fc and .te files for it
http://projects.edgewall.com/trac/wiki/TracWithSeLinux.
How would you recommend I go about this project. Does selinux contain a
system
for plugging in .te and .fc files so contexts are recognized during the
package install or
should I submitt these files for inclusion in the normal policy packages
and wait for it
to hit the fans?
Do anyone have any pointers to best practis in these situations? What
can the .spec file
do in order to keep track of selinux permissions etc.
Thankful for any help,
/Nicke

udev slowness and selinux
by Jason Dravet
Hello,
I am running todays rawhide and udev is still slow, but it is better than it
was. Here are some numbers:
booting with selinux disabled: udev starts in 5 seconds
booting with selinux enabled (libselinux-1.27.28-1): udev starts in 26
seconds.
booting with selinux enabled (older than libselinux-1.27.28-1): udev started
in 50-60 seconds.
I am running udev-075-4, kernel-2.6.14-1-1740, libselinux-1.27.28-1, and
selinux-policy-targeted-2.0.9-1. I am running selinux in targeted enforcing
mode.
Thanks,
Jason
