Tested with selinux-policy-3.13.1-160 1. selinux boolean virt_use_glusterd is available # getsebool -a | grep glusterd virt_use_glusterd --> on 2. When this boolean is set to 'on' and gfapi statedump could be triggered and written to /var/run/gluster (In reply to SATHEESARAN from comment #3) > Tested with selinux-policy-3.13.1-160 > > 1. selinux boolean virt_use_glusterd is available > # getsebool -a | grep glusterd > virt_use_glusterd --> on > > 2.

Description of problem: ----------------------- When triggering the statedump of gfapi application(QEMU), avc denial logged in audit.log and statedump is not dumped in to /var/run/gluster Version-Release number of selected component (if applicable): ------------------------------------------------------------- RHEL 7.3 ( 3.10.0-514.16.1.el7.x86_64 ) libselinux-utils-2.5-6.el7.x86_64 selinux-policy-3.13.1-102.el7_3.16.noarch libselinux-2.5-6.el7.x86_64 libselinux-python-2.5-6.el7.x86_64 selinux-policy-targeted-3.13.1-102.el7_3.16.noarch RHGS 3.3.0 interim build ( glusterfs-3.8.4-25.el7rhgs ) How reproducible: ------------------ Always Steps to Reproduce: ------------------- 1. Create a QEMU process that uses QEMU driver for glusterfs (libgfapi) 2. Trigger gfapi application statedump from gluster node Actual results: --------------- No gfapi statedump under /var/run/gluster and AVC denial message logged in audit.log Expected results: ----------------- gfapi application should dump the statedump under /var/run/gluster Additional info: ---------------- Snip from audit.log <snip> type=AVC msg=audit(1495796194.193:981): avc: denied { write } for pid=14873 comm="qemu-kvm" name="gluster" dev="tmpfs" ino=109984 scontext=system_u:system_r:svirt_t:s0:c399,c698 tcontext=system_u:object_r:glusterd_var_run_t:s0 tclass=dir </snip>
