Same here. Already a fix available? Me too. So I mean, this simple module fixes it of course:
module fix_haproxy 1.0;
require {
type haproxy_exec_t;
type haproxy_t;
class file execute_no_trans;
}
#============= haproxy_t ==============
allow haproxy_t haproxy_exec_t:file execute_no_trans;
Would be nice if the policy would be updated to include this permission, as HAProxy cannot do some of the more fancy stuff without this. Or at least make it a boolean or something.
Any progress? The module suggested by Erik Logtenberg works.(In reply to Erik Logtenberg from comment #3) > So I mean, this simple module fixes it of course: > > > module fix_haproxy 1.0; > > require { > type haproxy_exec_t; > type haproxy_t; > class file execute_no_trans; > } > > #============= haproxy_t ============== > allow haproxy_t haproxy_exec_t:file execute_no_trans; > > > > > Would be nice if the policy would be updated to include this permission, as > HAProxy cannot do some of the more fancy stuff without this.
