Michal, where is the socket located? We are missing /var/run/lvm(/.*)? gen_context(system_u:object_r:lvm_var_run_t,s0) on RHEL6. The socket is in its default location /var/run/lvm/lvmetad.socket. The location can be changed by environment variable LVM_LVMETAD_SOCKET, though. Yes we need that. We want the default labeling correct, if admin change the locations, they are responsible to change the labels. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory, and where to find the updated files, follow the link below.

Description of problem: When unconfined and unlabelednet modules are disabled, running automated test of lvmetad FAILes and causes AVCs. AVCs caused by test in permissive mode is listed below. The test PASSed with no AVCs with both mentioned modules enabled. ---- time->Wed Sep 5 14:53:17 2012 type=SYSCALL msg=audit(1346849597.163:29955): arch=c000003e syscall=49 success=yes exit=0 a0=4 a1=7fff2d04f090 a2=6e a3=ffffffff items=0 ppid=2827 pid=2828 auid=0 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=6 comm="lvmetad" exe="/sbin/lvmetad" subj=system_u:system_r:lvm_t:s0 key=(null) type=AVC msg=audit(1346849597.163:29955): avc: denied { create } for pid=2828 comm="lvmetad" name="lvmetad.socket" scontext=system_u:system_r:lvm_t:s0 tcontext=system_u:object_r:var_run_t:s0 tclass=sock_file ---- time->Wed Sep 5 14:53:19 2012 type=SYSCALL msg=audit(1346849599.297:29960): arch=c000003e syscall=87 success=yes exit=0 a0=406269 a1=7fff2d04ef80 a2=0 a3=0 items=0 ppid=1 pid=2828 auid=0 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=6 comm="lvmetad" exe="/sbin/lvmetad" subj=system_u:system_r:lvm_t:s0 key=(null) type=AVC msg=audit(1346849599.297:29960): avc: denied { unlink } for pid=2828 comm="lvmetad" name="lvmetad.socket" dev=sda3 ino=25177 scontext=system_u:system_r:lvm_t:s0 tcontext=system_u:object_r:var_run_t:s0 tclass=sock_file ---- time->Wed Sep 5 14:53:19 2012 type=SYSCALL msg=audit(1346849599.561:29961): arch=c000003e syscall=49 success=yes exit=0 a0=4 a1=7fffa25c8b20 a2=6e a3=ffffffff items=0 ppid=2879 pid=2880 auid=0 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=6 comm="lvmetad" exe="/sbin/lvmetad" subj=system_u:system_r:lvm_t:s0 key=(null) type=AVC msg=audit(1346849599.561:29961): avc: denied { create } for pid=2880 comm="lvmetad" name="lvmetad.socket" scontext=system_u:system_r:lvm_t:s0 tcontext=system_u:object_r:var_run_t:s0 tclass=sock_file Version-Release number of selected component (if applicable): selinux-policy-3.7.19-155.el6_3.noarch selinux-policy-targeted-3.7.19-155.el6_3.noarch lvm2-2.02.97-2.el6.x86_64 How reproducible: always Steps to Reproduce: 1. semodule -d unconfined; semodule -d unlabelednet 2.
