Description of problem:

While working on HA - VRRP, i got different AVCs errors




[root@networker-64ceac62-aeea-4364-bd8c-b7f0d6fcaeac ~]# cat  /var/log/audit/audit.log | audit2allow -r

require {
	type neutron_t;
	type neutron_var_lib_t;
	type keepalived_t;
	class process { signal sigkill };
	class capability dac_override;
	class file { write execute getattr read open ioctl execute_no_trans };
}

#============= keepalived_t ==============
allow keepalived_t neutron_t:process sigkill;
allow keepalived_t neutron_var_lib_t:file { write execute ioctl read open getattr execute_no_trans };
allow keepalived_t self:capability dac_override;

#============= neutron_t ==============
allow neutron_t keepalived_t:process signal;



[root@networker-5d12223d-d960-4803-a46c-d35d3ec18daa ~]# cat  /var/log/audit/audit.log | audit2allow -r

	class file { execute read create ioctl execute_no_trans write getattr unlink open };
	class system module_request;
	class dir { write remove_name add_name };
}

#============= keepalived_t ==============

#!!!! This avc can be allowed using the boolean 'domain_kernel_load_modules'
allow keepalived_t kernel_t:system module_request;
allow keepalived_t neutron_var_lib_t:dir { write remove_name add_name };
allow keepalived_t neutron_var_lib_t:file { execute read create getattr execute_no_trans write ioctl unlink open };

The problem is 

/var/lib/neutron/ha_confs/e4bc9b4e-d540-4d91-8e3e-9a8bf66317fe/notify_backup.sh

is created on the fly. Am I correct?

Comment 4 Ofer Blaut 2015-01-13 06:04:35 UTC
Adding , ACK

There was problem with vrrp, i didn't noticed if it is because of notify_backup.sh

I can only control HA by removing HA ports
