this year we have decided to adopt SELinux as part of our standard
platform. However we also build quite a few in-house RPM packages.
What we're trying to do now is to marry those two efforts, and make
those packages we build provide SELinux policies. Admittably we're
using RHEL6 for this purpose. I have already collected some
information, and it looks like building SELinux modules and
providing them with the package is the way to go.
I have started building module from scratch based on what we had to
do manually to get rid of SELinux warnings (running SELinux in
permissive mode at the moment):
$ chcon -R -h -t httpd_sys_content_t -u system_u /usr/libexec/foo*
$ chcon -R -t httpd_sys_rw_content_t -u system_u /var/lib/foo $
setsebool -P httpd_can_network_connect_db on
which resulted in policy:
with foo.if and foo.te pretty much empty.
What I struggle with are several things:
1. can I set up boolean's value from the policy module?
2. I had to manually relabel /usr/libexec/foo* and /var/lib/foo via
"fixfiles" after I added policy via:
$ semodule -i foo.pp
Can I create module in a way that upon it's activation it'll
relabel all needed pieces? (I played with semodule's "-d" and
with no effect)
3. I have seen several suggestions on how to package and install
.pp files with RPM:
latter seems to be more natural at least from logic/syntax
perspective. Which one is preferred for RHEL6 (I know it's a fedora
list, but I didn't see/find corresponsing RHEL list and sysadmin@
ML is kind of low on traffic and answers :( ).

In stead of adding a local policy module and setting a boolean, I
would do this all in one step.
semanage -S targeted -i - << _EOF
boolean -m --on httpd_can_network_connect_db
fcontext -a -t httpd_sys_content_t '/usr/libexec/foo(.*)?'
fcontext -a -t httpd_sys_rw_content_t '/var/lib/foo(/*)?'
restorecon -R -v /usr/libexec/foo /var/lib/foo
