Does tuned actually have to read the disk device? This basically would allow it to read any file on the system. What does $ ls -Z `which hdparm` I believe you will need to fix labeling on your system. Dan, tuned is so close unconfined domain. $ ls -Z `which hdparm` -rwxr-xr-x. root root unconfined_u:object_r:fsadm_exec_t:s0 /usr/sbin/hdparm Yes I think we should make it unconfined by default. Lets add a fsadm_domtrans though |
Description of problem: SELinux is preventing hdparm from 'read' accesses on the blk_file sda. ***** Plugin catchall (100. confidence) suggests ************************** If sie denken, dass es hdparm standardmässig erlaubt sein sollte, read Zugriff auf sda blk_file zu erhalten. Then sie sollten dies als Fehler melden. Um diesen Zugriff zu erlauben, können Sie ein lokales Richtlinien-Modul erstellen. Do zugriff jetzt erlauben, indem Sie die nachfolgenden Befehle ausführen: # grep hdparm /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:tuned_t:s0 Target Context system_u:object_r:fixed_disk_device_t:s0 Target Objects sda [ blk_file ] Source hdparm Source Path hdparm Port <Unbekannt> Host (removed) Source RPM Packages hdparm-9.43-5.fc20.x86_64 Target RPM Packages Policy RPM selinux-policy-3.12.1-83.fc20.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.11.1-300.fc20.x86_64 #1 SMP Sat Sep 14 15:01:23 UTC 2013 x86_64 x86_64 Alert Count 3 First Seen 2013-09-28 12:07:35 CEST Last Seen 2013-09-28 12:19:28 CEST Local ID f2a60dee-fa56-43fd-a9e3-fb2673cde61c Raw Audit Messages type=AVC msg=audit(1380363568.221:434): avc: denied { read } for pid=3145 comm="hdparm" name="sda" dev="devtmpfs" ino=6615 scontext=system_u:system_r:tuned_t:s0 tcontext=system_u:object_r:fixed_disk_device_t:s0 tclass=blk_file type=SYSCALL msg=audit(1380363568.221:434): arch=x86_64 syscall=open success=no exit=EACCES a0=7fff3ae8af8e a1=800 a2=0 a3=19 items=0 ppid=568 pid=3145 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 ses=4294967295 tty=(none) comm=hdparm exe=/usr/sbin/hdparm subj=system_u:system_r:tuned_t:s0 key=(null) Hash: hdparm,tuned_t,fixed_disk_device_t,blk_file,read Additional info: reporter: libreport-2.1.7 hashmarkername: setroubleshoot kernel: 3.11.1-300.fc20.x86_64 type: libreport
