<p class=MsoNormal>Hi<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>I've got an executable file script.sh labeled
xyz_exec_t. I've also defined a domain xyz_t and added
daemon_domain(xyz_t, xyz_exec_t) in the .te file.<o:p></o:p></p>
</div>
<div>
<div>
<p class=MsoNormal>When compiled and inserted, the file context labels
seem to be enforced correctly. Normally the executable script.sh is invoked by
the init scripts. As per the domain transition rule, I expect it show up xyz_t
as its domain in ps -efZ . But the transition does not work as expected. The
process runs as an unconfined domain. <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>But when I add runcon in the line where the init script
invokes the executable with the domain as xyz_t, the process runs in the proper
context.<o:p></o:p></p>
</div>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>Once I remove the runcon and invoke the init script, the
domain transition I applied in the custom module does not work out. <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>Any suggestions ? <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>NB: The system is on permissive mode and this particular
domain xyz_t has also been defined as a permissive domain. <o:p></o:p></p>

<p class=MsoNormal><span style='color:#1F497D'>It might help us to see the exact
rules that have been defined. Hopefully this will show something up
(thanks Dominick!):<o:p></o:p></span></p>

<p class=MsoNormal><span style='color:#1F497D'>If your executable is normally
run by init scripts, it will be coming from initrc_t, not unconfined_t, which
