While setting up GFS2 on f17, I got some SELinux denials: SELinux is preventing /usr/sbin/dlm_controld from 'read, write' accesses on the file qb-cfg-request-1344-1564-16-header. ***** Plugin catchall (100. confidence) suggests *************************** If you believe that dlm_controld should be allowed read write access on the qb-cfg-request-1344-1564-16-header file by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # grep dlm_controld /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:dlm_controld_t:s0 Target Context system_u:object_r:corosync_tmpfs_t:s0 Target Objects qb-cfg-request-1344-1564-16-header [ file ] Source dlm_controld Source Path /usr/sbin/dlm_controld Port <Unknown> Host gnode1.example.com Source RPM Packages dlm-3.99.5-1.fc17.x86_64 Target RPM Packages Policy RPM selinux-policy-3.10.0-145.fc17.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name gnode1.example.com Platform Linux gnode1.example.com 3.5.1-1.fc17.x86_64 #1 SMP Thu Aug 9 17:50:43 UTC 2012 x86_64 x86_64 Alert Count 2 First Seen 2012-08-17 11:00:09 EDT Last Seen 2012-08-17 11:00:59 EDT Local ID 2bf1bba5-2330-4698-a353-245cbf4b58bf Raw Audit Messages type=AVC msg=audit(1345215659.222:123): avc: denied { read write } for pid=1564 comm="dlm_controld" name="qb-cfg-request-1344-1564-16-header" dev="tmpfs" ino=20970 scontext=system_u:system_r:dlm_controld_t:s0 tcontext=system_u:object_r:corosync_tmpfs_t:s0 tclass=file type=AVC msg=audit(1345215659.222:123): avc: denied { open } for pid=1564 comm="dlm_controld" path="/dev/shm/qb-cfg-request-1344-1564-16-header" dev="tmpfs" ino=20970 scontext=system_u:system_r:dlm_controld_t:s0 tcontext=system_u:object_r:corosync_tmpfs_t:s0 tclass=file type=SYSCALL msg=audit(1345215659.222:123): arch=x86_64 syscall=open success=yes exit=EBADF a0=7fff43a39270 a1=2 a2=180 a3=7fff43a38e80 items=0 ppid=1 pid=1564 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm=dlm_controld exe=/usr/sbin/dlm_controld subj=system_u:system_r:dlm_controld_t:s0 key=(null) Hash: dlm_controld,dlm_controld_t,corosync_tmpfs_t,file,read,write audit2allow #============= dlm_controld_t ============== #!!!!
