Description Radek Novacek 2013-07-25 07:41:08 EDT
+++ This bug was initially created as a clone of Bug #988330 +++

OpenLMI-Networking provider needs a policy. This is similar request as bz979037 and bz983422 and bz987951.

Network provider manages network devices using NetworkManager via D-Bus.

Audit messages are attached.

Result of `ausearch -m avc -ts 12:16 | audit2allow`, with my comments:

#============= NetworkManager_t ==============
allow NetworkManager_t dhcpc_t:process { siginh noatsecure rlimitinh };
# ^^^ this doesn't seems to be related

#============= firewalld_t ==============
allow firewalld_t iptables_t:process { siginh noatsecure rlimitinh };
# ^^^ this doesn't seems to be related

#============= pegasus_openlmi_networking_t ==============
allow pegasus_openlmi_networking_t passwd_file_t:file { read getattr open };
allow pegasus_openlmi_networking_t pegasus_data_t:dir write;
allow pegasus_openlmi_networking_t proc_net_t:file { read getattr open };
allow pegasus_openlmi_networking_t self:capability { setuid net_admin setgid };
allow pegasus_openlmi_networking_t self:netlink_route_socket { write getattr read bind create nlmsg_read };
allow pegasus_openlmi_networking_t self:udp_socket { create connect getattr };
allow pegasus_openlmi_networking_t sysfs_t:file { read write getattr open };
allow pegasus_openlmi_networking_t sysfs_t:lnk_file read;
allow pegasus_openlmi_networking_t system_dbusd_t:unix_stream_socket connectto;
allow pegasus_openlmi_networking_t system_dbusd_var_run_t:dir search;
allow pegasus_openlmi_networking_t system_dbusd_var_run_t:sock_file write;

#!!!! This avc can be allowed using the boolean 'global_ssp'
allow pegasus_openlmi_networking_t urandom_device_t:chr_file { read open };

#============= pegasus_t ==============
allow pegasus_t chkpwd_t:process { siginh noatsecure rlimitinh };
allow pegasus_t pegasus_openlmi_networking_t:process { siginh noatsecure rlimitinh };

Please check if the permission is reasonable for networking-handling provider. 
What the provider does:
* D-Bus communication with NetworkManager
* reading /proc/net/dev
* reading /sys/class/net/*/flags
* generating UUIDs with libuuid
* communication with pegasus (same for all providers)
