<div class=Section1>
<p class=MsoPlainText>I have an app which runs from xinetd in the myapp_t
domain:<o:p></o:p></p>
<p class=MsoPlainText>
system_u:system_r:myapp_t<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>I am attempting to get myapp to exec the chfn program<o:p></o:p></p>
<p class=MsoPlainText>however it reports:<o:p></o:p></p>
<p class=MsoPlainText>chfn: system_u:system_r:myapp_t:SystemLow-SystemHigh is
not authorized to change the finger info of test5<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>I have tried these macros from the reference policy:<o:p></o:p></p>
<p class=MsoPlainText>usermanage_run_chfn(myapp_t,system_r,devpts_t )<o:p></o:p></p>
<p class=MsoPlainText>type myapp_devpts_t;<o:p></o:p></p>
<p class=MsoPlainText>type myapp_tty_device_t;<o:p></o:p></p>
<p class=MsoPlainText>userdom_change_password_template(myapp)<o:p></o:p></p>
<p class=MsoPlainText>usermanage_run_chfn(myapp_t,system_r,{ myapp_devpts_t
myapp_tty_device_t })<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>but things still don't work.<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>SELinux is not reporting denials in audit.log, presumably
because<o:p></o:p></p>
<p class=MsoPlainText>chfn calls security_compute_av() and reports the
"denial" itself.<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Is there policy I can write that will allow myapp to exec
chfn?<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Thanks,<o:p></o:p></p>
