Bug 1305757

Description of problem:
Opened a PDF file on a samba share from a virtual machine. I have no idea why samba is opening /usr/bin/ssmtp and /usr/bin/wodim. I have reported these before on earlier Fedora versions with no resolution.
SELinux is preventing /usr/sbin/smbd from 'getattr' accesses on the file /usr/bin/wodim.

*****  Plugin samba_share (75.5 confidence) suggests   ***********************

If you want to allow smbd to have getattr access on the wodim file
Then you need to change the label on '/usr/bin/wodim'
Do
# semanage fcontext -a -t samba_share_t '/usr/bin/wodim'
# restorecon  -v '/usr/bin/wodim'

*****  Plugin catchall_boolean (12.2 confidence) suggests   ******************

If you want to allow samba to share any file/directory read only.
Then you must tell SELinux about this by enabling the 'samba_export_all_ro' boolean.
You can read 'None' man page for more details.
Do
setsebool -P samba_export_all_ro 1

If you want to allow samba to share any file/directory read/write.
Then you must tell SELinux about this by enabling the 'samba_export_all_rw' boolean.
You can read 'None' man page for more details.
Do
setsebool -P samba_export_all_rw 1

If you believe that smbd should be allowed getattr access on the wodim 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 smbd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
