Description of problem: $ sudo livecd-iso-to-disk --format --efi Fedora-19-x86_64-netinst.iso /dev/sdb SELinux is preventing /usr/sbin/useradd from 'ioctl' accesses on the file /dev/null. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that useradd should be allowed ioctl access on the null 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 useradd /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context unconfined_u:unconfined_r:useradd_t:s0-s0:c0.c1023 Target Context unconfined_u:object_r:device_t:s0 Target Objects /dev/null [ file ] Source useradd Source Path /usr/sbin/useradd Port <Unknown> Host (removed) Source RPM Packages shadow-utils-4.1.5.1-8.fc20.x86_64 Target RPM Packages Policy RPM selinux-policy-3.12.1-75.fc20.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name (removed) Platform Linux (removed) 3.11.0-3.fc20.x86_64 #1 SMP Tue Sep 3 21:52:28 UTC 2013 x86_64 x86_64 Alert Count 4 First Seen 2013-09-05 13:50:53 MSK Last Seen 2013-09-05 13:51:23 MSK Local ID 7a923795-eced-47c9-9693-8b589f543d54 Raw Audit Messages type=AVC msg=audit(1378374683.424:908): avc: denied { ioctl } for pid=13760 comm="useradd" path="/dev/null" dev="sda2" ino=3943313 scontext=unconfined_u:unconfined_r:useradd_t:s0-s0:c0.c1023 tcontext=unconfined_u:object_r:device_t:s0 tclass=file type=SYSCALL msg=audit(1378374683.424:908): arch=x86_64 syscall=ioctl success=no exit=ENOTTY a0=1 a1=5401 a2=7fffaf66a050 a3=7fffaf66a020 items=0 ppid=13753 pid=13760 auid=1000 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 ses=5 tty=pts0 comm=useradd exe=/usr/sbin/useradd subj=unconfined_u:unconfined_r:useradd_t:s0-s0:c0.c1023 key=(null) Hash: useradd,useradd_t,device_t,file,ioctl Additional info: reporter: libreport-2.1.6 hashmarkername: setroubleshoot kernel: 3.11.0-3.fc20.x86_64 type: libreport
