Description Milos Malik 2012-04-10 18:44:40 UTC 
Description of problem:


Version-Release number of selected component (if applicable):
selinux-policy-targeted-3.7.19-145.el6.noarch
selinux-policy-doc-3.7.19-145.el6.noarch
selinux-policy-mls-3.7.19-145.el6.noarch
selinux-policy-3.7.19-145.el6.noarch
selinux-policy-minimum-3.7.19-145.el6.noarch
rusers-server-0.17-61.el6.x86_64

How reproducible:
always

Steps to Reproduce:
# service rusersd status
rpc.rusersd is stopped
# service rstatd status
rpc.rstatd is stopped
# run_init service rusersd start
Authenticating root.
Password: 
Starting rusers services:                                  [  OK  ]
# run_init service rstatd start
Authenticating root.
Password: 
Starting rstat services:                                   [  OK  ]
# service rusersd status
rpc.rusersd (pid 14248) is running...
# service rstatd status
rpc.rstatd (pid 14266) is running...
# ps -efZ | grep initrc_t
system_u:system_r:initrc_t:s0   nobody   14248     1  0 20:42 ?        00:00:00 rpc.rusersd
system_u:system_r:initrc_t:s0   root     14266     1  0 20:42 ?        00:00:00 rpc.rstatd

#

Actual results:
* both rpc.rstatd and rpc.rusersd run as initrc_t

Expected results:
* both rpc.rstatd and rpc.rusersd run in their own SELinux domain
Comment 1 Milos Malik 2012-04-10 20:45:21 UTC 
The daemon is not confined by SELinux. Please help SELinux folks to create a suitable policy module. You know that we should minimize the number of programs running as initrc_t, don't you?
Comment 2 Honza Horak 2012-04-16 12:38:39 UTC 
I tried to sum up some potential SELinux-related actions. However, re-assigning to selinux-policy, since I'm not able to write the rules myself. Hope the following helps; if any questions, just ask.

rstatd:
* daemonizes: fork + setsid
* writes log messages to Syslog
* reads /proc/stat
* reads /proc/net/dev
* reads /proc/diskstats
* reads /proc/uptime
* reads /proc/loadavg
* registers rpcbind services (udp socket):
    100001    3   udp   rstatd
    100001    2   udp   rstatd
    100001    1   udp   rstatd

rusersd:
* daemonizes: fork + setsid
* writes log messages to Syslog
* getutent()
* stat(/dev/ttyX)
* registers rpcbind services (udp socket):
    100002    3   udp   rusersd
    100002    2   udp   rusersd
Comment 3 RHEL Program Management 2012-07-10 08:19:54 UTC 
This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.
Comment 4 RHEL Program Management 2012-07-11 01:55:45 UTC 
This request was erroneously removed from consideration in Red Hat Enterprise Linux 6.4, which is currently under development.  This request will be evaluated for inclusion in Red Hat Enterprise Linux 6.4.
