ldconfig denials during mock builds
by Todd Zullinger
Hi,
I recently noticed some problems when building packages for rawhide
with mock. The mock logs have a log of these:
/sbin/ldconfig: Can't create temporary cache file /etc/ld.so.cache~: Permission denied
error: %postun(glibc-2.6-4.i686) scriptlet failed, exit status 1
The audit messages look like this:
avc: denied { read } for comm="ldconfig" dev=sda2 egid=502 euid=0 exe="/sbin/ldconfig" exit=-13 fsgid=502 fsuid=0 gid=502 items=0 name="lib" pid=4247 scontext=user_u:system_r:ldconfig_t:s0 sgid=502 subj=user_u:system_r:ldconfig_t:s0 suid=0 tclass=dir tcontext=user_u:object_r:var_lib_t:s0 tty=(none) uid=0
avc: denied { write } for comm="ldconfig" dev=sda2 egid=502 euid=0 exe="/sbin/ldconfig" exit=-13 fsgid=502 fsuid=0 gid=502 items=0 name="etc" pid=4247 scontext=user_u:system_r:ldconfig_t:s0 sgid=502 subj=user_u:system_r:ldconfig_t:s0 suid=0 tclass=dir tcontext=user_u:object_r:var_lib_t:s0 tty=(none) uid=0
I'm guessing this has to do with the contexts on etc:
$ ll -dZ /etc/ /var/lib/mock/fedora-development-i386/root/etc/
drwxr-xr-x root root system_u:object_r:etc_t /etc/
drwxrwsr-x build mock user_u:object_r:var_lib_t /var/lib/mock/fedora-development-i386/root/etc/
Is this something that needs to be fixed in mock or in the selinux
policy?
Thanks,

selinux-policy-targeted no src directory ?
by MARK ROWE
Hi All,
Please can someone suggest a solution to the following, I am not that familiar with Linux and have been tasked to re-configure 2 existing servers that cannot be upgraded due to company policy etc:
I have 2 servers running MySQL on Fedora Core 4 and need to set them up for master/slave replication. This I have done but have found that SELinux is stopping the mysqld on the slave from making a network connection to the master.
I downloaded selinux-policy-targeted-1.23.16-6.noarch.rpm and installed it with no errors reported but it failed to create the /etc/selinux/targeted/src directory. I tried several times at installing the package but each time it failed to create the right directories.
Can anyone suggest how I can get this installed correctly or how I can get SELinux to allow mysqld network connection without it?
Regards,
Mark.

Or setup a transition from the SGE Daemons to sshd_t:s0-SystemHigh

Need help with SELinux and SGE/ssh
by Orion Poplawski
I'm running Sun Grid Engine on a CentOS 5 cluster and am having trouble
with SELinux preventing the proper setup of parallel environments.
Turning SELinux off allows everything to work properly.
The problem seems to be when SGE tries to use ssh to login to a remote
machine. As part of this process, it starts up a private sshd daemon to
handle the connection. The relevant error appears to be:
type=USER_LOGIN msg=audit(1186001097.981:19489): user pid=12066 uid=0
auid=0 subj=root:system_r:unconfined_t:s0-s0:c0.c1023 msg='acct=steph:
exe="/usr/sbin/sshd" (hostname=?, addr=192.168.0.120, terminal=sshd
res=failed)'

selected-context=user_u:system_r:unconfined_t:s0-s0:c0.c1023:
exe="/usr/sbin/sshd" (hostname=?, addr=?, terminal=? res=failed)'
sshd reports:
Aug 1 14:44:58 coop00 sshd[12066]: error: deny MLS level
SystemLow-SystemHigh (user range s0). Continuing in permissive mode
I'm at a loss here. Can anyone explain what is going on and what is
failing? How can I make it work without running in permissive mode?
Thanks!

[ANN] SETools 3.3 Release
by Christopher J. PeBenito
A new release of SETools is now available on the Tresys OSS site, from
http://oss.tresys.com. The primary changes this release are performance
enhancements, especially for source policies, the ability to select
which AV rules are compared (allow and dontaudit only, for example) in
sediff and sediffx, and a rewrite of libsefs with C++. The complete
change log for this release follows.
SETools 3.3:
SETools:
* SETools now has an external dependency upon libsqlite3 >= 3.2. The
supplied configure script will enforce this dependency.
* pkg-config scripts are installed with the SETools libraries.
libsefs:
* Rewrite of library to have proper namespaces and much more usable
object-oriented design.
* SWIG wrappers generated for this library if the appropriate
configure flags are set.
findcon, searchcon:
* Merge searchcon's functionality into findcon. The searchcon tool
has been removed from SETools.
indexcon, replcon:
* Updated to use new libsefs design.
apol:
* Updated to use new libsefs design.
* Modified to use the SWIG Tcl interface rather than a custom C
library. apol is now a combination of a Tcl script (simply called
'apol') and associated packages that are required at runtime.
* Neverallow rules are only loaded and expanded when the user
performs a search for them. This will dramatically speed up
initial policy load time.
awish:
* awish is no longer needed and thus has been removed from SETools.
sediff, sediffx:
* Instead of differentiating "AV rules" or "TE rules", user now
specifies which particular rule to compare (allow, dontaudit,
type_transition, etc.).
* Neverallow rules are only loaded and expanded when the user
performs a diff upon them. This will dramatically speed up
initial policy load time.

Policycoreutils man pages translation to Russian language
by Andrey Markelov
Hello,
I translated all 20 man pages from policycoreutils to Russian language. Before that work I had some experiences with translation (as example translation to Russian RHEL4 doc in A.B.A. Inventa - http://www.rhd.ru/docs/). So, i hope that my translation - ok. Also, translation was checked by my colleague - RHCX. Is it possible to include translated pages in policycoreutils package?
Also i open ticket #250741 in bugzilla.

newrole?
by bradley
I recently have decided I was going to play with selinux. Before I set
the selinux value to enforcing I read up on it online and saw that to
change my privileges I need to use the newrole command. It seemed
simple enough, but I don't seem to have this command and there's also no
man page on it. When I checked fedora forums some one had the same
problem, and the only reply to it was to send an email here. Does
anyone have any information that can help me out? I am using fedora 7
on a thinkpad T60 by the way.
