Command
# runcon -t spacewalk_monitoring_t -- perl -MDBI -e 'DBI->connect("dbi:Oracle:rhnsat", "rhnsat", "rhnsat", { RaiseError => 1 });'
generates the AVC on s390x while it does not on i386. The syscall is
bind(3, {sa_family=AF_INET, sin_port=htons(0), sin_addr=inet_addr("127.0.0.1")}, 16) = 0
I'm trying to figure out what's different on s390x vs. i386.
The problems stems from the fact that on s390x, the tcontext is lo_node_t:
type=AVC msg=audit(1243501001.030:2467): avc: denied { node_bind } for pid=3344 comm="test-bind-0" saddr=127.0.0.1
scontext=root:system_r:test_bind_t:s0-s0:c0.c1023 tcontext=system_u:object_r:lo_node_t:s0 tclass=udp_socket
while on i386 it's node_t:
type=AVC msg=audit(1243497648.065:717): avc: denied { node_bind } for pid=25329 comm="test-bind-0" saddr=127.0.0.1 scontext=root:system_r:test_bind_t:s0-s0:c0.c1023 tcontext=system_u:object_r:node_t:s0 tclass=udp_socket
corenet_udp_bind_all_nodes(spacewalk_monitoring_t) was added in cf44bdce656294f4181424b6843366258eda428a for bug 498930, so that addresses that type=AVC msg=audit(1242054323.116:367): avc: denied { node_bind } for pid=27887 comm="Monitoring" saddr=127.0.0.1 scontext=root:system_r:spacewalk_monitoring_t:s0 tcontext=system_u:object_r:lo_node_t:s0 tclass=udp_socket denial. The httpd_sys_script_t denial fixed in commit c8588264c801e5cddaa288e8ef17ae839ff32e7e.

Description of problem: Satellite-5.3.0-RHEL5-re20090507.1 installation on s390x / RHEL-5, monitoring & monitoring scout enabled, selinux enabled: # grep 'denied.*node_bind' audit.log type=AVC msg=audit(1242054323.116:367): avc: denied { node_bind } for pid=27887 comm="Monitoring" saddr=127.0.0.1 scontext=root:system_r:spacewalk_monitoring_t:s0 tcontext=system_u:object_r:lo_node_t:s0 tclass=udp_socket type=AVC msg=audit(1242117348.626:800): avc: denied { node_bind } for pid=1540 comm="upload_results." saddr=127.0.0.1 scontext=root:system_r:httpd_sys_script_t:s0 tcontext=system_u:object_r:lo_node_t:s0 tclass=udp_socket Version-Release number of selected component (if applicable): oracle-nofcontext-selinux-0.1-23.8.1.el5sat spacewalk-monitoring-selinux-0.5.7-2.el5sat How reproducible: Always Steps to Reproduce: 1. Install Satellite 5.3.0 on RHEL-5, selinux enabled. 2. Activate monitoring + monitoring scout 3. Watch /var/log/audit/audit.log Actual results: SELinux denials Expected results: No denials.
