Should be fixed in selinux-policy-3.13.1-13.el7 or higher. I'm going to close this bug as a duplicate of the RHEL bug that is tracking the issue, since Spacewalk does not own the selinux-policy package. *** This bug has been marked as a duplicate of bug 1154242 *** This BZ closed some time during 2.5, 2.6 or 2.7. Adding to 2.7 tracking bug. |
Description of problem: Using osad on CentOS 7 logs several AVC and prevents it from working. Most AVCs look similar to the ones introduced with CentOS 6.6 (See #1161288). The following AVCs are logged on osad startup: time->Wed Feb 4 17:16:12 2015 type=SYSCALL msg=audit(1423066572.058:8509): arch=c000003e syscall=2 success=yes exit=3 a0=7fa84d9ed3a7 a1=80000 a2=1b6 a3=0 items=0 ppid=9843 pid=9844 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm="osad" exe="/usr/bin/python2.7" subj=system_u:system_r:osad_t:s0 key=(null) type=AVC msg=audit(1423066572.058:8509): avc: denied { open } for pid=9844 comm="osad" path="/etc/resolv.conf" dev="dm-0" ino=17018233 scontext=system_u:system_r:osad_t:s0 tcontext=system_u:object_r:net_conf_t:s0 tclass=file type=AVC msg=audit(1423066572.058:8509): avc: denied { read } for pid=9844 comm="osad" name="resolv.conf" dev="dm-0" ino=17018233 scontext=system_u:system_r:osad_t:s0 tcontext=system_u:object_r:net_conf_t:s0 tclass=file ---- time->Wed Feb 4 17:16:12 2015 type=SYSCALL msg=audit(1423066572.058:8510): arch=c000003e syscall=5 success=yes exit=0 a0=3 a1=7fff6641bba0 a2=7fff6641bba0 a3=0 items=0 ppid=9843 pid=9844 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm="osad" exe="/usr/bin/python2.7" subj=system_u:system_r:osad_t:s0 key=(null) type=AVC msg=audit(1423066572.058:8510): avc: denied { getattr } for pid=9844 comm="osad" path="/etc/resolv.conf" dev="dm-0" ino=17018233 scontext=system_u:system_r:osad_t:s0 tcontext=system_u:object_r:net_conf_t:s0 tclass=file ---- time->Wed Feb 4 17:16:12 2015 type=SYSCALL msg=audit(1423066572.058:8511): arch=c000003e syscall=41 success=yes exit=3 a0=2 a1=1 a2=6 a3=0 items=0 ppid=9843 pid=9844 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm="osad" exe="/usr/bin/python2.7" subj=system_u:system_r:osad_t:s0 key=(null) type=AVC msg=audit(1423066572.058:8511): avc: denied { create } for pid=9844 comm="osad" scontext=system_u:system_r:osad_t:s0 tcontext=system_u:system_r:osad_t:s0 tclass=tcp_socket ---- time->Wed Feb 4 17:16:12 2015 type=SYSCALL msg=audit(1423066572.058:8512): arch=c000003e syscall=42 success=yes exit=0 a0=3 a1=7fff6641ded0 a2=10 a3=0 items=0 ppid=9843 pid=9844 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm="osad" exe="/usr/bin/python2.7" subj=system_u:system_r:osad_t:s0 key=(null) type=AVC msg=audit(1423066572.058:8512): avc: denied { name_connect } for pid=9844 comm="osad" dest=443 scontext=system_u:system_r:osad_t:s0 tcontext=system_u:object_r:http_port_t:s0 tclass=tcp_socket type=AVC msg=audit(1423066572.058:8512): avc: denied { connect } for pid=9844 comm="osad" scontext=system_u:system_r:osad_t:s0 tcontext=system_u:system_r:osad_t:s0 tclass=tcp_socket ---- time->Wed Feb 4 17:16:12 2015 type=SYSCALL msg=audit(1423066572.573:8513): arch=c000003e syscall=42 success=yes exit=0 a0=3 a1=7fff6641e530 a2=10 a3=3 items=0 ppid=9843 pid=9844 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm="osad" exe="/usr/bin/python2.7" subj=system_u:system_r:osad_t:s0 key=(null) type=AVC msg=audit(1423066572.573:8513): avc: denied { name_connect } for pid=9844 comm="osad" dest=5222 scontext=system_u:system_r:osad_t:s0 tcontext=system_u:object_r:jabber_client_port_t:s0 tclass=tcp_socket ---- time->Wed Feb 4 17:16:12 2015 type=SYSCALL msg=audit(1423066572.625:8517): arch=c000003e syscall=54 success=yes exit=0 a0=3 a1=1 a2=9 a3=7fff6641ee5c items=0 ppid=1 pid=9845 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm="osad" exe="/usr/bin/python2.7" subj=system_u:system_r:osad_t:s0 key=(null) type=AVC msg=audit(1423066572.625:8517): avc: denied { setopt } for pid=9845 comm="osad" laddr=1.2.3.212 lport=49717 faddr=1.2.3.212 fport=5222 scontext=system_u:system_r:osad_t:s0 tcontext=system_u:system_r:osad_t:s0 tclass=tcp_socket Backporting some changes from rawhide selinux-policy makes osad work. Scheduling package updates work and osad ping works, too. The following local policy fixes the issues: policy_module(osad-selinux,1.0) require { type jabber_client_port_t; type osad_t; } corenet_tcp_connect_http_port(osad_t) corenet_tcp_connect_jabber_client_port(osad_t) corecmd_exec_bin(osad_t) dev_read_urand(osad_t) auth_use_nsswitch(osad_t) optional_policy(` rpm_domtrans(osad_t) ') Maybe less permissions are needed, but due to unavailability of an selinux-policy package from RHEL 7.1, I was unable to check, whether the issues were already addressed in newer policy. Version-Release number of selected component (if applicable): On CentOS 7.0: selinux-policy-3.12.1-153.el7_0.13 osad-5.11.52-1.el7 How reproducible: Always Steps to Reproduce: 1. Install osad 2. Start osad Actual results: osad fails to start and AVCs are logged Expected results: osad starts up and works Additional info:
