    NAME

    samba_selinux - Security Enhanced Linux Policy for Samba
     
    

    DESCRIPTION

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

    FILE_CONTEXTS

    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
    If you want to make this permanant, i.e. survive a relabel, you must add an entry to the file_contexts.local file.
    /etc/selinux/POLICYTYPE/contexts/files/file_contexts.local

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

     

    SHARING FILES

    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

     

    BOOLEANS


    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 boolean.

    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

    You can disable SELinux protection for the samba daemon by executing:

    setsebool -P smbd_disable_trans 1
    service smb restart

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