Hello
I am using CentOS 6.4 and I want to store the logs from openswan
into a different file ( /var/log/ipsec ) than the default. For this
purpose I added
plutostderrlog=/var/log/ipsec
to ipsec.conf.
As long as I keep the server in permissive mode, openswan starts
OK. If, however, I switch to enforcing, the daemon refuses to start with
the following error message displayed in the console:
ipsec_setup: Starting Openswan IPsec
U2.6.32/K3.0.78-1.el6.elrepo.x86_64...
ipsec_setup: Cannot write to "/var/log/ipsec".
The audit log does not record anything useful so I tried to switch
dontaudit to off and see if anything useful comes out. After running
audit2allow and a bit of trial and error I came out with the following
custom policy :
module myipsec 1.0;
require {
type ipsec_t;
type var_log_t;
class file { write ioctl getattr append };
}
#============= ipsec_mgmt_t ==============
allow ipsec_mgmt_t var_log_t:file write;
The above policy worked for me but I am wondering if it is OK (I am
mostly confused by the fact that the class includes " write ioctl
getattr append " but the rule has only "write" ). And, assuming it is OK
can this custom policy ( or the corrected one if needed ) be included in
the default policy ?
TIA
