I don’t know what this is but I DON’T want to allow it and I don’t want to see this in the audit log anymore

First off 3 terms:

• SElinux – Security-Enhanced Linux (SELinux) is a Linux feature that provides a mechanism for supporting access control security policies, including U.S. Department of Defense style mandatory access controls, through the use of Linux Security Modules (LSM) in the Linux kernel. (wikipedia)
• ProLiant Support Packs (PSP) represent operating system (OS) specific bundles of ProLiant optimized drivers, utilities, and management agents.
• RHEL (Red Hat Enterprise Linux) – CentOS (Community ENTerprise Operating System, RHEL Clone)

So basicly what I did to get rid of these messages is that I wrote a new module called pspignore to ignore, without allowing them. Here’s what I did:

Make a local directory for my modules

mkdir -p /etc/selinux/local

cd /etc/selinux/local

Download my custom module which include “dontaudit” for these conditions.

wget http://tommi.org/static/ignorepsp.te

Build the module and install it

checkmodule -M -m -o ignorepsp.mod ignorepsp.te

semodule_package -o ignorepsp.pp -m ignorepsp.mod

semodule -i ignorepsp.pp

That should be it. The main thing can be found at the bottom of ignorepsp.te:

dontaudit ifconfig_t device_t:chr_file { read write };
dontaudit ifconfig_t initrc_t:netlink_route_socket { read write };

Hope this is helpfull.

Install packages:

oracle-instantclient11.1-basic-11.1.0.7.0-1.x86_64.rpm
oracle-instantclient11.1-devel-11.1.0.7.0-1.x86_64.rpm
oracle-instantclient11.1-sqlplus-11.1.0.7.0-1.x86_64.rpm

Put the relevant libraries into the textrel_shlib_t context:

semanage fcontext -a -t textrel_shlib_t /usr/lib/oracle/11.1/client64 /lib/libnnz11.so
semanage fcontext -a -t textrel_shlib_t /usr/lib/oracle/11.1/client64/lib/libclntsh.so.11.1
semanage fcontext -a -t textrel_shlib_t /usr/lib/oracle/11.1/client64/lib/libsqlplus.so
semanage fcontext -a -t textrel_shlib_t /usr/lib/oracle/11.1/client64/lib/libociei.so
semanage fcontext -a -t textrel_shlib_t /usr/lib/oracle/11.1/client64/lib/libsqlplusic.so
restorecon -R -v /usr/lib/oracle/11.1/client64/lib/

Put the libraries into the path of the dynamic library loader

echo "export ORACLE_HOME=/usr/lib/oracle/11.1/client64" > /etc/profile.d/oracle.sh

Set the path to the tnsnames.ora, I like /etc/tnsnames.ora

echo “export TNS_ADMIN=/etc/tnsnames.ora” >> /etc/profile.d/oracle.sh

Of course you have to have a valid tnsnames.ora file available.

Logout and login to update your environment and voila, you should be able to run sqlplus, install perl-DBD-Oracle or php-oci8, python, whatever your flavor is..

Ohh, and merry christmas!
