       samba_selinux - Security Enhanced Linux Policy for Samba


       Security-Enhanced Linux secures the Samba server via flexible mandatory
       access control.


       SELinux requires files to have an extended attribute to define the file
       type.   Policy  governs the access daemons have to these files.  If you
       want to share files other than home directories, those  files  must  be
       labeled samba_share_t.  So if you created a special directory /var/eng,
       you would need to label the directory with the chcon tool.

       chcon -t samba_share_t /var/eng

       To make this change permanent (survive a  relabel),  use  the  semanage
       command to add the change to file context configuration:

       semanage fcontext -a -t samba_share_t "/var/eng(/.*)?"

       This      command      adds      the      following      entry       to

       /var/eng(/.*)? system_u:object_r:samba_share_t:s0

       Run the restorecon command to apply the changes:

       restorecon -R -v /var/eng/


       If you want to share files with multiple domains (Apache,  FTP,  rsync,
       Samba),   you   can   set   a  file  context  of  public_content_t  and
       public_content_rw_t.  These context allow any of the above  domains  to
       read  the  content.   If  you  want a particular domain to write to the
       public_content_rw_t domain,  you  must  set  the  appropriate  boolean.
       allow_DOMAIN_anon_write.  So for samba you would execute:

       setsebool -P allow_smbd_anon_write=1


       SELinux  policy  is customizable based on least access required.  So by
       default SElinux policy turns off SELinux sharing  of  home  directories
       and  the use of Samba shares from a remote machine as a home directory.

       If you are setting up this machine as a Samba server and wish to  share
       the  home  directories,  you  need  to  set  the samba_enable_home_dirs

              setsebool -P samba_enable_home_dirs 1

       If you want to use a remote Samba server for the  home  directories  on
       this machine, you must set the use_samba_home_dirs boolean.

              setsebool -P use_samba_home_dirs 1

       system-config-selinux is a GUI  tool  available  to  customize  SELinux
       policy settings.
