NAME

       mozilla_selinux - Security Enhanced Linux Policy for the mozilla processes

DESCRIPTION

       Security-Enhanced Linux secures the mozilla processes via flexible mandatory access control.

       The  mozilla  processes execute with the mozilla_t SELinux type. You can check if you have these processes running by executing the ps com-
       mand with the -Z qualifier.

       For example:

       ps -eZ | grep mozilla_t

ENTRYPOINTS

       The mozilla_t SELinux type can be entered via the mozilla_exec_t file type.

       The default entrypoint paths for the mozilla_t domain are the following:

       /usr/lib/[^/]*firefox[^/]*/firefox, /usr/lib/[^/]*firefox[^/]*/firefox-bin, /usr/lib/mozilla[^/]*/reg.+,  /usr/lib/mozilla[^/]*/mozilla-.*,
       /usr/lib/firefox[^/]*/mozilla-.*,  /usr/bin/mozilla-[0-9].*,  /usr/lib/netscape/.+/communicator/communicator-smotif.real, /usr/bin/mozilla-
       bin-[0-9].*, /usr/bin/mozilla, /usr/bin/netscape, /usr/bin/epiphany, /usr/bin/epiphany-bin, /usr/lib/galeon/galeon,  /usr/bin/mozilla-snap-
       shot, /usr/lib/netscape/base-4/wrapper

PROCESS TYPES

       SELinux defines process types (domains) for each process running on the system

       You can see the context of a process using the -Z option to ps

       Policy  governs the access confined processes have to files.  SELinux mozilla policy is very flexible allowing users to setup their mozilla
       processes in as secure a method as possible.

       The following process types are defined for mozilla:

       mozilla_t, mozilla_plugin_config_t, mozilla_plugin_t

       Note: semanage permissive -a mozilla_t can be used to make the process type mozilla_t permissive. SELinux does not deny access  to  permis-
       sive process types, but the AVC (SELinux denials) messages are still generated.

BOOLEANS

       SELinux	policy	is  customizable based on least access required.  mozilla policy is extremely flexible and has several booleans that allow
       you to manipulate the policy and run mozilla with the tightest access possible.

       If you want to allow confined web browsers to read home directory content, you must turn on the mozilla_read_content boolean.  Disabled	by
       default.

       setsebool -P mozilla_read_content 1

       If  you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd server, you must turn on the authlo-
       gin_nsswitch_use_ldap boolean. Disabled by default.

       setsebool -P authlogin_nsswitch_use_ldap 1

       If you want to deny user domains applications to map a memory region as both executable and writable, this is dangerous and the	executable
       should be reported in bugzilla, you must turn on the deny_execmem boolean. Enabled by default.

       setsebool -P deny_execmem 1

       If  you	want  to  deny	any  process  from ptracing or debugging any other processes, you must turn on the deny_ptrace boolean. Enabled by
       default.

       setsebool -P deny_ptrace 1

       If you want to allow all domains to use other domains file descriptors, you must turn on the domain_fd_use boolean. Enabled by default.

       setsebool -P domain_fd_use 1

       If you want to allow all domains to have the kernel load modules, you must turn on  the	domain_kernel_load_modules  boolean.  Disabled	by
       default.

       setsebool -P domain_kernel_load_modules 1

       If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.

       setsebool -P fips_mode 1

       If you want to enable reading of urandom for all domains, you must turn on the global_ssp boolean. Disabled by default.

       setsebool -P global_ssp 1

       If you want to allow confined applications to run with kerberos, you must turn on the kerberos_enabled boolean. Enabled by default.

       setsebool -P kerberos_enabled 1

       If you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.

       setsebool -P nis_enabled 1

       If you want to allow confined applications to use nscd shared memory, you must turn on the nscd_use_shm boolean. Enabled by default.

       setsebool -P nscd_use_shm 1

       If  you	want  to  allow  regular  users  direct dri device access, you must turn on the selinuxuser_direct_dri_enabled boolean. Enabled by
       default.

       setsebool -P selinuxuser_direct_dri_enabled 1

       If you want to allow unconfined executables to make their stack executable.  This should never, ever be	necessary.  Probably  indicates  a
       badly  coded  executable,  but  could  indicate	an  attack.  This  executable  should be reported in bugzilla, you must turn on the selin-
       uxuser_execstack boolean. Enabled by default.

       setsebool -P selinuxuser_execstack 1

       If you want to support ecryptfs home directories, you must turn on the use_ecryptfs_home_dirs boolean. Disabled by default.

       setsebool -P use_ecryptfs_home_dirs 1

       If you want to support fusefs home directories, you must turn on the use_fusefs_home_dirs boolean. Disabled by default.

       setsebool -P use_fusefs_home_dirs 1

       If you want to support NFS home directories, you must turn on the use_nfs_home_dirs boolean. Disabled by default.

       setsebool -P use_nfs_home_dirs 1

       If you want to support SAMBA home directories, you must turn on the use_samba_home_dirs boolean. Disabled by default.

       setsebool -P use_samba_home_dirs 1

       If you want to allows clients to write to the X server shared memory segments, you must turn  on  the  xserver_clients_write_xshm  boolean.
       Disabled by default.

       setsebool -P xserver_clients_write_xshm 1

       If you want to support X userspace object manager, you must turn on the xserver_object_manager boolean. Enabled by default.

       setsebool -P xserver_object_manager 1

NSSWITCH DOMAIN

       If  you	want  to allow users to resolve user passwd entries directly from ldap rather then using a sssd server for the mozilla_plugin_con-
       fig_t, mozilla_t, mozilla_plugin_t, you must turn on the authlogin_nsswitch_use_ldap boolean.

       setsebool -P authlogin_nsswitch_use_ldap 1

       If you want to allow confined applications to run with kerberos for the mozilla_plugin_config_t, mozilla_t, mozilla_plugin_t, you must turn
       on the kerberos_enabled boolean.

       setsebool -P kerberos_enabled 1

FILE CONTEXTS

       SELinux requires files to have an extended attribute to define the file type.

       You can see the context of a file using the -Z option to ls

       Policy governs the access confined processes have to these files.  SELinux mozilla policy is very flexible allowing users  to  setup  their
       mozilla processes in as secure a method as possible.

       STANDARD FILE CONTEXT

       SELinux	defines the file context types for the mozilla, if you wanted to store files with these types in a diffent paths, you need to exe-
       cute the semanage command to sepecify alternate labeling and then use restorecon to put the labels on disk.

       semanage fcontext -a -t mozilla_conf_t '/srv/mozilla/content(/.*)?'
       restorecon -R -v /srv/mymozilla_content

       Note: SELinux often uses regular expressions to specify labels that match multiple files.

       The following file types are defined for mozilla:

       mozilla_conf_t

       - Set files with the mozilla_conf_t type, if you want to treat the files as mozilla configuration  data,  usually  stored  under  the  /etc
       directory.

       mozilla_exec_t

       - Set files with the mozilla_exec_t type, if you want to transition an executable to the mozilla_t domain.

       Paths:
	    /usr/lib/[^/]*firefox[^/]*/firefox, 	       /usr/lib/[^/]*firefox[^/]*/firefox-bin,		      /usr/lib/mozilla[^/]*/reg.+,
	    /usr/lib/mozilla[^/]*/mozilla-.*, /usr/lib/firefox[^/]*/mozilla-.*, /usr/bin/mozilla-[0-9].*, /usr/lib/netscape/.+/communicator/commu-
	    nicator-smotif.real,  /usr/bin/mozilla-bin-[0-9].*,  /usr/bin/mozilla,  /usr/bin/netscape,	/usr/bin/epiphany,  /usr/bin/epiphany-bin,
	    /usr/lib/galeon/galeon, /usr/bin/mozilla-snapshot, /usr/lib/netscape/base-4/wrapper

       mozilla_home_t

       - Set files with the mozilla_home_t type, if you want to store mozilla files in the users home directory.

       Paths:
	    /home/[^/]*/.lyx(/.*)?,   /home/[^/]*/.java(/.*)?,	 /home/[^/]*/.adobe(/.*)?,   /home/[^/]*/.gnash(/.*)?,	 /home/[^/]*/.webex(/.*)?,
	    /home/[^/]*/.galeon(/.*)?,		/home/[^/]*/.spicec(/.*)?,	   /home/[^/]*/.IBMERS(/.*)?,	      /home/[^/]*/POkemon.*(/.*)?,
	    /home/[^/]*/.mozilla(/.*)?, /home/[^/]*/.phoenix(/.*)?, /home/[^/]*/.icedtea(/.*)?,  /home/[^/]*/.netscape(/.*)?,  /home/[^/]*/.quake-
	    live(/.*)?,   /home/[^/]*/.ICAClient(/.*)?,   /home/[^/]*/.macromedia(/.*)?,  /home/[^/]*/.thunderbird(/.*)?,  /home/[^/]*/.gcjwebplu-

	    /home/[^/]*/abc, /home/[^/]*/.gnashpluginrc

       mozilla_plugin_config_exec_t

       - Set files with the mozilla_plugin_config_exec_t type, if you want to transition an executable to the mozilla_plugin_config_t domain.

       mozilla_plugin_exec_t

       - Set files with the mozilla_plugin_exec_t type, if you want to transition an executable to the mozilla_plugin_t domain.

       Paths:
	    /usr/lib/xulrunner[^/]*/plugin-container,	/usr/lib/nspluginwrapper/npviewer.bin,	 /usr/bin/nspluginscan,   /usr/bin/nspluginviewer,
	    /usr/lib/firefox/plugin-container

       mozilla_plugin_rw_t

       - Set files with the mozilla_plugin_rw_t type, if you want to treat the files as mozilla plugin read/write content.

       mozilla_plugin_tmp_t

       - Set files with the mozilla_plugin_tmp_t type, if you want to store mozilla plugin temporary files in the /tmp directories.

       mozilla_plugin_tmpfs_t

       - Set files with the mozilla_plugin_tmpfs_t type, if you want to store mozilla plugin files on a tmpfs file system.

       mozilla_tmp_t

       - Set files with the mozilla_tmp_t type, if you want to store mozilla temporary files in the /tmp directories.

       mozilla_tmpfs_t

       - Set files with the mozilla_tmpfs_t type, if you want to store mozilla files on a tmpfs file system.

       Note:  File context can be temporarily modified with the chcon command.	If you want to permanently change the file context you need to use
       the semanage fcontext command.  This will modify the SELinux labeling database.	You will need to use restorecon to apply the labels.

COMMANDS

       semanage fcontext can also be used to manipulate default file context mappings.

       semanage permissive can also be used to manipulate whether or not a process type is permissive.

       semanage module can also be used to enable/disable/install/remove policy modules.

       semanage boolean can also be used to manipulate the booleans

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