avcs for readahead :(
by Antonio Olivares
Dear fellow testers and Selinux experts,
Upon applying the most recent updates, I am encountering some denied avcs for readahead. I previously posted about readahead, but i got no response, maybe implying that they are not important or that it is okay for selinux to step in and stop readhead from creating trouble.
SELinux: initialized (dev binfmt_misc, type binfmt_misc), uses genfs_contexts
type=1400 audit(1220049017.315:7): avc: denied { fowner } for pid=653 comm="readahead" capability=3 scontext=system_u:system_r:readahead_t:s0 tcontext=system_u:system_r:readahead_t:s0 tclass=capability

Postfix, /root/.forward, SELinux, F9, Strange AVC
by Brian Chadwick
Hi All.
Well, I have scoured the docs and cant find anything that looks like the
problem I am having here.
I have a .forward file in /root .. Mail to root should divert to my user
account, but SELinux stops Postfix from doing so. If I set SELinux to
permissive, then it works, but of course logs the same AVC.
SETroubleshooter says to restorecon -R './root' ... ./root is a relative
path ... so what does this mean? It doesnt work.
[root@admin ~]# restorecon -R -v './root'
restorecon: stat error on ./root: No such file or directory
[root@admin ~]#
.forward File Context:
[root@admin ~]# ls -Z /root/.forward
-rw-r--r-- root root unconfined_u:object_r:admin_home_t:s0 /root/.forward

Postix Booleans:

allow_user_postgresql_connect --> off

Output from Troubleshooter:
Summary
SELinux is preventing the local from using potentially mislabeled files
(./root).
Detailed Description
SELinux has denied local access to potentially mislabeled file(s)
(./root). This means that SELinux will not allow local to use these
files. It is common for users to edit files in their home directory or
tmp directories and then move (mv) them to system directories. The
problem is that the files end up with the wrong file context which
confined applications are not allowed to access.
Allowing Access
If you want local to access this files, you need to relabel them using
restorecon -v './root'. You might want to relabel the entire directory
using restorecon -R -v './root'.

Troubleshooter says to restorecon for ./root. What is this? .. That is a
relative path, not a full path.
Can anyone help decipher this AVC and provide a fix?

SELinux and Nagios (Fedora 9 + Nagios)
by dbcooper
Hello,
I've setup (via default yum repos) Nagios (nagios-2.11-3.fc9.i386 and all
the needed plugs).
I'm getting the following messages when using SELinux in Target/Enabled
mode.
My knowledge is very limited with SELinux and I'm trying to learn the proper
way to troubleshoot/resolve issues on my own, and hopefully I can use
this as my firts learning curve with it.
Thanks for any suggestions.
---------------------------------------------------------------------------------------------------------------
Summary:
SELinux is preventing ping (ping_t) "read" to

SELinux denied access requested by ping. It is not expected that this access
is
required by ping 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

selinux - nspluginscan, and xine denials
by Antonio Olivares
Two alerts from selinux
Summary:
SELinux is preventing nspluginviewer from changing a writable memory segment
executable.
Detailed Description:
The nspluginviewer application attempted to change the access protection of
memory (e.g., allocated using malloc). This is a potential security problem.
Applications should not be doing this. Applications are sometimes coded
incorrectly and request this permission. The SELinux Memory Protection Tests
(http://people.redhat.com/drepper/selinux-mem.html) web page explains how to
remove this requirement. If nspluginviewer does not work and you need it to
work, you can configure SELinux temporarily to allow this access until the
application is fixed. Please file a bug report
(http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this package.
Allowing Access:
If you trust nspluginviewer to run correctly, you can change the context of the
executable to unconfined_execmem_exec_t. "chcon -t unconfined_execmem_exec_t
'/usr/bin/nspluginviewer'". You must also change the default file context files
on the system in order to preserve them even on a full relabel. "semanage
fcontext -a -t unconfined_execmem_exec_t '/usr/bin/nspluginviewer'"
Fix Command:
chcon -t unconfined_execmem_exec_t '/usr/bin/nspluginviewer'

I have recently installed xine(xine-lib-1.1.15 and xine-ui from source) and I got this one immediately following:
What should I do? Should I just apply the fix and move on?
Summary:
SELinux is preventing xine from making the program stack executable.
Detailed Description:
The xine application attempted to make its stack executable. This is a potential
security problem. This should never ever be necessary. Stack memory is not
executable on most OSes these days and this will not change. Executable stack
memory is one of the biggest security problems. An execstack error might in fact
be most likely raised by malicious code. Applications are sometimes coded
incorrectly and request this permission. The SELinux Memory Protection Tests
(http://people.redhat.com/drepper/selinux-mem.html) web page explains how to
remove this requirement. If xine does not work and you need it to work, you can
configure SELinux temporarily to allow this access until the application is
fixed. Please file a bug report
(http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this package.
Allowing Access:
Sometimes a library is accidentally marked with the execstack flag, if you find
a library with this flag you can clear it with the execstack -c LIBRARY_PATH.
Then retry your application. If the app continues to not work, you can turn the
flag back on with execstack -s LIBRARY_PATH. Otherwise, if you trust xine to run
correctly, you can change the context of the executable to
unconfined_execmem_exec_t. "chcon -t unconfined_execmem_exec_t '/usr/bin/xine'"
You must also change the default file context files on the system in order to
preserve them even on a full relabel. "semanage fcontext -a -t
unconfined_execmem_exec_t '/usr/bin/xine'"
Fix Command:
chcon -t unconfined_execmem_exec_t '/usr/bin/xine'

[BUG] legacy typenames of se-postgresql still remain

I got the following access denied logs, when I tries to connect
SE-PostgreSQL (postgresql_t) from PHP script (httpd_t) via unix
domain socket (/tmp/.s.PGSQL.5432).
type=AVC msg=audit(1218613044.484:10388): avc: denied { write }

However, both permissions are allowed via postgresql_stream_connect()
independent from any booleans, if required types are provided by
postgresql.te.
postgresql_stream_connect() and postgresql_unpriv_client() are put
within same optional_policy section at apache.te.
postgresql_unpriv_client() requires trusted procedure related types,
but postgresql.te declares them in legacy names.
old: sepgsql_trusted_domain_t --> new: sepgsql_trusted_proc_t
old: sepgsql_trusted_proc_t --> new: sepgsql_trusted_proc_exec_t
Could you apply the attached patch?
It fixes them as upstream doing.

file contexts change on reboot

I'm not sure, but I think I'm hitting a precedence issue which is

The situation is a standard RHEL5.2 with all errata applied; plus the
following modifications
I have a local policy modification introduced by one rpm:
/usr/sbin/semanage fcontext -a -t var_log_t -s system_u
'/var/opt/ft/log'
And a separate policy module containing:
/var/opt/ft/log/libft_.* --
gen_context(system_u:object_r:lsb-ft-asn_rw_t,s0)
The net result is:
root@lstlinux57 14:56:56 ~> semanage fcontext -l | grep '/opt/ft'
/var/opt/ft/asn(/.*)? all files
system_u:object_r:lsb-ft-asn_rw_t:s0

system_u:object_r:var_log_t:s0
/var/opt/ft/log/snmpd\.log all files

I suspect that the problem lies with the ordering of those
'/var/opt/ft/log' lines. Am I on the right track? How can I sort
things out?

Clamd getting out of hand...
by Arthur Dent
Hello All,
I have been using SELinux in enforcing mode on my F8 box for some time
now. I had to go through a bit of pain to get clamassassin working with
clamd to scan my emails but it worked OK.
This weekend I upgraded to F9 and have now had about a gazillion AVC
denials related to clamd.
I have therefore been forced to use audit2allow to add to the already
pretty cumbersome local policy I had with F8.
I list the policy below. All of the entries are as a result of some
denial and subsequent audit2allow policy generation.
My question is basically - can one of you gurus tell me if all this
stuff is still necessary? Is there a policy in the works that might
avoid all this?
Thanks in advance

nspluginwrapper policy issue
by Rahul Sundaram
Hi,
Summary:
SELinux is preventing npviewer.bin (nsplugin_t) "getattr" to /dev/dri/card0
(dri_device_t).
Detailed Description:
SELinux denied access requested by npviewer.bin. It is not expected that
this
access is required by npviewer.bin 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:
Sometimes labeling problems can cause SELinux denials. You could try to
restore
the default system file context for /dev/dri/card0,
restorecon -v '/dev/dri/card0'
If this does not work, there is currently no automatic way to allow this
access.
Instead, 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)

Realplayer problem
by Rahul Sundaram
Hi
Summary:
SELinux is preventing the plugin-config (nsplugin_config_t) from executing
/opt/real/RealPlayer/mozilla/nphelix.so.
Detailed Description:
SELinux has denied the plugin-config from executing
/opt/real/RealPlayer/mozilla/nphelix.so. If plugin-config is supposed to
be able
to execute /opt/real/RealPlayer/mozilla/nphelix.so, this could be a labeling
problem. Most confined domains are allowed to execute files labeled
bin_t. So
you could change the labeling on this file to bin_t and retry the
application.
If this plugin-config is not supposed to execute
/opt/real/RealPlayer/mozilla/nphelix.so, this could signal a intrusion
attempt.
Allowing Access:
If you want to allow plugin-config to execute
/opt/real/RealPlayer/mozilla/nphelix.so: chcon -t bin_t
'/opt/real/RealPlayer/mozilla/nphelix.so' If this fix works, please
update the
file context on disk, with the following command: semanage fcontext -a
-t bin_t
'/opt/real/RealPlayer/mozilla/nphelix.so' Please specify the full path
to the
executable, Please file a bug report
(http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this
selinux-policy
to make sure this becomes the default labeling.
