Memory protection and system-config-securitylevel
by Kamil J. Dudek
Hello everybody
Forgive me, if this subject has already been mentioned here, but I
simply couldn't find answer anywhere.
Few days ago I started system-config-securitylevel. I found something
interesting in "Modify SELinux policies". A memory protection - there
are four options in there. Two of them are enabled, with a description
that if having this enabled is required by some program, it should be
reported to bugzilla. I didn't do it, because of very strange effects
after turning it off.
Disabling
"Allow all executable files to map memory areas as executable and
readable, which is dangerous and such program should be reported to
bugzilla"
and
"Allow all executable files to mark stack as executable.That shouldn't
ever be required"
option(translation from polish) made system act very strange. First
thing I've observed was that Kobo game stopped working. GMPC stopped
playing. Also stuff outside of Fedora like Java and NVidia drivers
failed. So I should have "reported to bugzilla" to many application to
make it have any sense. Such bug report would be only annoying but
according to system-config-securitylevel...
What is it with these two options? To make everything work properly they
should be enabled, but their description that they should be disabled is
confusing.
Thank you and forgive me any mess I've done by this post

mount point labels
by Clarkson, Mike R (US SSA)
I'm attempting to create the labeled mount point with the following
command:
mount -t nfs -o context=system_u:object_r:import_file_t:s0
nas:/vol/home /home/SimulatedImport/output/home
The mount point is created without any errors, but the label that I
specify in the mount command is not used. Instead of
system_u:object_r:import_file_t, the context of the
/home/SimulatedImport/output/home is system_u:object_r:nfs_t:s0.
ls -dZ /home/SimulatedImport/output/home
drwxr-xr-x root root system_u:object_r:nfs_t:s0
/home/m252/SimulatedImport/output/home
I'm running RHEL5 with a policy built as mls off of the targeted policy.
Does anyone know why the context label is not taking?
Thanks

I get these AVCs when running from xinetd and making a client

I tried creating and loading a policy module:
# grep "rsync" /var/log/audit/audit.log | audit2allow -M rsyncd
# semodule -i rsyncd.pp
Here is rsyncd.te:
module rsyncd 1.0;
require {

type rsync_t;
class netlink_route_socket create;
class file { read write };
}
#============= rsync_t ==============
allow rsync_t self:netlink_route_socket create;
allow rsync_t var_run_t:file { read write };
But I still get these AVCs:

Additionally, when using xinetd I don't ever get any log messages in
/var/log/rsyncd.log like I do when I run "rsync --daemon" directly:

Sendmail milters in Fedora 8
by Paul Howarth
Since upgrading my mail server from Fedora 7 to Fedora 8, I've come
across some problems with the sockets used for communication between
sendmail and two of the "milter" plugins I'm using with it, namely
milter-regex and spamass-milter. It's very likely that other milters
will have similar issues.
The sockets used are created when the milter starts, as follows:
milter-regex:
/var/spool/milter-regex/sock (var_spool_t, inherited from parent directory)
spamass-milter:
/var/run/spamass-milter/spamass-milter.sock (spamd_var_run_t, in policy)
These are pretty well the upstream locations, though I'm open to moving
the milter-regex socket from /var/spool to /var/run or elsewhere for
consistency.
Since moving to Fedora 8, I've had to add the following to local policy
to get these milters working:
allow sendmail_t spamd_var_run_t:dir { search getattr };
allow sendmail_t spamd_var_run_t:sock_file { getattr write };
allow sendmail_t var_spool_t:sock_file { getattr write };
allow sendmail_t initrc_t:unix_stream_socket { read write connectto };
The last of these is the strangest, and relates to Bug #425958
(https://bugzilla.redhat.com/show_bug.cgi?id=425958). Whilst the socket
file itself has the context listed above, the unix domain socket that
sendmail connects to is still initrc_t, as can be seen from the output
of "netstat -lpZ":
...
unix 2 [ ACC ] STREAM LISTENING 14142
5853/spamass-milter system_u:system_r:initrc_t:s0
/var/run/spamass-milter/spamass-milter.sock
unix 2 [ ACC ] STREAM LISTENING 13794
5779/milter-regex system_u:system_r:initrc_t:s0
/var/spool/milter-regex/sock
...
So, my questions are:
1. Why are the sockets still initrc_t?
2. Is this a kernel issue or a userspace issue that should be fixed in
the milters?
3. Should there be a standard place for milter sockets to live, and if
so, where?
4. How come this worked OK in Fedora 7 and previous releases?
Paul.

Fedora buildsys and SELinux
by Karsten Wade
As announced on fedora-devel-list[1], we'd like to come to a resolution
(consensus, actions) on the challenges we have with SELinux in the
Fedora build system.
I expect the following:
* All the parties are here now needed to figure this out
* Someone better than me is going to reply with specifics about what is
not working in the buildsys
* We all agree it's pretty important to get this figured out in a good
way
One example of a project blocking on this work is the Fedora spin
server. We would have to put a non-SELinux secured server in the loop
somewhere for the actual spin building, and any way we do that is going
to be hacky and whacky.
The main problem I see outside of the technical issues is a marketing
one. Fedora's infrastructure is a set of open tools that anyone can
download and make work themselves. We know that people do that. Fedora
Infrastructure is a feature producer; just as Fedora Docs supplies a
full-course documentation toolchain, so does Infrastructure supply a
full-course FLOSS project toolset.[2]
We do *not* want to be explaining that a new feature doesn't work with
SELinux. At the very minimum, we have been consistent about the value
of SELinux in Fedora, and to ship something as a Fedora feature that
cannot run under SELinux ... well, that would be bad.
This is why other Fedora folks are asking the Fedora SELinux team to
take this off the backburner.
Thanks - Karsten
[1] https://www.redhat.com/archives/fedora-devel-list/2008-April/msg01064.html
[2] Yep, that's right; Fedora Infrastructure is a feature of Fedora.
For example, the new grid project 'Fedora Sleepwalker' is looking to get
integrated into firstboot or some kind of JoinBuddy. When that happens,
adding your install to the Fedora Sleepwalker grid is going to be touted
as a major feature for that release.

Starting stunnel from xinetd
by Ian Pilcher
Running fully updated Fedora 8, trying to start stunnel from xinetd, and
getting a couple of denials:
type=AVC msg=audit(1205149512.996:2338): avc: denied { write } for

Aren't these things that stunnel should be expected to do?

postfix with maildir delivery
by freeslkr
Hello,
I'm trying out SELinux on Fedora 8 in permissive mode. I get AVCs
everytime postfix delivers mail to the maildir directories. It looks
like postfix doesn't have permission to create files. For example,
from /var/log/messages:
SELinux is preventing local (postfix_local_t) "link" to
./1208923427.P3686.myhost (mail_spool_t)
from /var/log/audit/audit.log:
type=AVC msg=audit(1208923427.350:95): avc: denied { link } for
pid=3686 comm="local" name="1208923427.P3686.myhost" dev=dm-3
ino=819271 scontext=system_u:system_r:postfix_local_t:s0
tcontext=system_u:object_r:mail_spool_t:s0 tclass=file
type=SYSCALL msg=audit(1208923427.350:95): arch=c000003e
syscall=86 success=yes exit=0 a0=2aaaaad599c0 a1=2aaaaad59ba0
a2=0 a3=0 items=0 ppid=2371 pid=3686 auid=4294967295 uid=0 gid=0
euid=1000 suid=0 fsuid=1000 egid=1000 sgid=0 fsgid=1000 tty=(none)
comm="local" exe="/usr/libexec/postfix/local"
subj=system_u:system_r:postfix_local_t:s0 key=(null)
Is my interpretation correct. If so, is it likely that this could be
corrected in a future policy version?
Thank you for you help

Gmail is buggy for some reason. I' ll try and keep this coherent. On
the i686 box, after I found and killed gam_server( i had to do it
twice for it to stay dead) I then got a couple more AVC's (posting
AVC's and observations follow):
SELinux is preventing iptables (iptables_t) "read write" to socket (fail2ban_t).
Detailed Description:
SELinux denied access requested by iptables. It is not expected that this access
is required by iptables and this access may signal an intrusion attempt. It is
also possible that the specific version or configuration of the application is
causing it to require additional access.
Allowing Access:
You can generate a local policy module to allow this access - see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Or you can disable
SELinux protection altogether. Disabling SELinux protection is not recommended.
Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi)
against this package.

Ok. That one is about iptables. Soon as I started fail2ban , the log
showed 3 AVC's as above. Stop Fail2ban and three more generated. Did
it twice to see if it was consistent. Started fail2ban twice, each
time I started it generated 3 AVC's as above, same when I stopped it ,
generated 3 AVC's per instance. So 12 total. When I stopped Fail2ban,
within a couple of minutes(can't be more exact didn't have a stop
watch) saw a new AVC(only after it stops, observations follow AVC):

Ok. After I stop Fail2ban i get one instance of this AVC related to
gam_server. I started and stopped Fail2ban twice so two AVC's related
to gam_server, once after each time I stop fail2ban. No I don't think
anyone is stupid, just being clear for my sake and yours. Also ran :
ps -eZ | grep rpm_t gam_server still dead. That was on i686 box. BTW
had to kill gam_server twice on x86_64 box for it to stay dead, same
as on i686. The x86_64 box is the same for the iptables AVC. Same
ratio, 3 AVC's generated when starting fail2ban and 3 AVC's when
stopping fail2ban. The difference is that the AVC generated after you
stop fail2ban is related to sendmail(observations follow AVC):

Checked processes on x86_64 no sendmail was or is running. Service
isn't usually running and isn't now.
Looks like a policy bug or both boxes have been tampered with, you
tell me, Sulphur is here so they will get nuked soon enough. The
sendmail bug may explain the strange behavior I have seen out of
Thunderbird and Gmail but sendmail AVC is only generated on x86_64
box, which incidentally is where I saw wierd behavior out of
Thunderbird but that may be separate issue, I don't think there is
enough evidence yet to make that conclusion despite my feeling that it
is related, i'll just have to keep my eyes peeled. I would file a bug
report but I'd like to understand this first so I might suggest, even
if I can't code, a fix but if you have to explain it ...the bug would
end up being read by someone that subscribes to this list so.....let
me know, I will file it if you ask me to. If logs, etc are needed I
will supply them but if its a genuine bug it should be easily
reproducible in under 30 minutes. I checked for processes running as
fs_t and system_mail_t before, during, and after starting/stopping
fail2ban on x86_64 box, I don't see anything. I feel like i am
forgetting something, anyway let me know about the bug report or if
you want more logs etc...
Thanks,
