Created attachment 825730 [details]

Description of problem:
Support for physical disks was added to the OpenLMI Hardware provider. To provide this information, it needs access to smartctl and lsblk programs.

Please, add appropriate policies to the RHEL-7 and Fedora 20+.

What is a path to OpenLMI Hardware provider?
Comment 3 Peter Schiffer 2013-11-19 09:16:59 EST
It should be:
Comment 4 Miroslav Grepl 2013-11-19 10:52:27 EST
We probably want to add a new openlmi type using

$ cat mypol.te

# make -f /usr/share/selinux/devel/Makefile mypol.pp
# semodule -i mypol.pp
# chcon -t pegasus_openlmi_hardware_exec_t /usr/libexec/pegasus/cmpiLMI_Hardware-cimprovagt

re-test and collect all AVC msgs.

recollected AVC msgs
Comment 6 Miroslav Grepl 2013-11-19 13:19:16 EST
Something is wrong.

ls -lZ /usr/libexec/pegasus/cmpiLMI_Hardware-cimprovagt
Comment 7 Peter Schiffer 2013-11-20 05:43:14 EST
# ls -lZ /usr/libexec/pegasus/cmpiLMI_Hardware-cimprovagt
-rwxr-xr-x. root root unconfined_u:object_r:pegasus_openlmi_hardware_exec_t:s0 /usr/libexec/pegasus/cmpiLMI_Hardware-cimprovagt
Comment 8 Miroslav Grepl 2013-11-21 05:12:05 EST
Which is OK. We should not see pegasus_t but pegasus_openlmi_hardware_t.

Comment 10 Miroslav Grepl 2013-11-21 09:04:55 EST
could you try to play around the policy from the comment #4.
Comment 11 Miroslav Grepl 2013-12-09 15:44:07 EST
Any update?

this is the latest avc log for the whole hardware provider (after calling all classes and associations).

Also, output of audit2allow says:

#============= pegasus_openlmi_hardware_t ==============
allow pegasus_openlmi_hardware_t dmidecode_exec_t:file { read getattr
open execute execute_no_trans };
allow pegasus_openlmi_hardware_t fixed_disk_device_t:blk_file { read
getattr open ioctl };
allow pegasus_openlmi_hardware_t fsadm_exec_t:file { read execute open
getattr execute_no_trans };
allow pegasus_openlmi_hardware_t hwdata_t:file { read getattr open };
allow pegasus_openlmi_hardware_t memory_device_t:chr_file { read open };
allow pegasus_openlmi_hardware_t self:capability sys_rawio;
allow pegasus_openlmi_hardware_t udev_var_run_t:file { read getattr open };

Do you need any other information to update selinux policy? Please don't forget we need it on both, RHEL-7 and Fedora 20+.


Comment 13 Miroslav Grepl 2014-01-07 12:06:22 EST
pegasus_openlmi_hardware_t is what I wanted to see.

    Add support for cmpiLMI_Hardware-cimprovagt provider
Comment 17 Tomas Smetana 2014-01-24 07:26:30 EST
Sorry for the late update: I re-did the steps in comment #4:

[root@rawhide-local ~]# ls -lZ /usr/libexec/pegasus/cmpiLMI_Hardware-cimprovagt
-rwxr-xr-x. root root unconfined_u:object_r:pegasus_openlmi_hardware_exec_t:s0 /usr/libexec/pegasus/cmpiLMI_Hardware-cimprovagt

So this seems to be OK.
