NAME

       mailman_mail_selinux - Security Enhanced Linux Policy for the mailman_mail processes

DESCRIPTION

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

       The mailman_mail processes execute with the mailman_mail_t SELinux type. You can check if you have these processes running by executing the
       ps command with the -Z qualifier.

       For example:

       ps -eZ | grep mailman_mail_t

ENTRYPOINTS

       The mailman_mail_t SELinux type can be entered via the mailman_mail_exec_t file type.

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

       /usr/mailman.*/mail/wrapper,    /usr/lib/mailman.*/mail/mailman,    /usr/lib/mailman.*/mail/wrapper,	/usr/lib/mailman.*/bin/mailmanctl,
       /usr/lib/mailman.*/scripts/mailman,  /usr/lib/mailman.*/bin/mm-handler.*,  /usr/share/doc/mailman.*/mm-handler.*,  /usr/lib/mailman/bin/mm-
       handler.*, /usr/lib/mailman/bin/mailmanctl

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 mailman_mail policy is very flexible allowing  users  to  setup  their
       mailman_mail processes in as secure a method as possible.

       The following process types are defined for mailman_mail:

       mailman_mail_t

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

BOOLEANS

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

       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 allow all daemons to write corefiles to /, you must turn on the daemons_dump_core boolean. Disabled by default.

       setsebool -P daemons_dump_core 1

       If you want to enable cluster mode for daemons, you must turn on the daemons_enable_cluster_mode boolean. Enabled by default.

       setsebool -P daemons_enable_cluster_mode 1

       If you want to allow all daemons to use tcp wrappers, you must turn on the daemons_use_tcp_wrapper boolean. Disabled by default.

       setsebool -P daemons_use_tcp_wrapper 1

       If you want to allow all daemons the ability to read/write terminals, you must turn on the daemons_use_tty boolean. Disabled by default.

       setsebool -P daemons_use_tty 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 mailman to access FUSE file systems, you must turn on the mailman_use_fusefs boolean. Disabled by default.

       setsebool -P mailman_use_fusefs 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

NSSWITCH DOMAIN

       If you want to allow users to resolve user passwd entries directly from ldap rather then using a sssd server for  the  mailman_mail_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 mailman_mail_t, you must turn on the kerberos_enabled boolean.

       setsebool -P kerberos_enabled 1

MANAGED FILES

       The SELinux process type mailman_mail_t can manage files labeled with the following file types.	The paths listed are the default paths for
       these file types.  Note the processes UID still need to have DAC permissions.

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 mailman_mail policy is very flexible	allowing  users  to  setup
       their mailman_mail processes in as secure a method as possible.

       STANDARD FILE CONTEXT

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

       semanage fcontext -a -t mailman_mail_exec_t '/srv/mailman_mail/content(/.*)?'
       restorecon -R -v /srv/mymailman_mail_content

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

       The following file types are defined for mailman_mail:

       mailman_mail_exec_t

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

       Paths:
	    /usr/mailman.*/mail/wrapper,  /usr/lib/mailman.*/mail/mailman,   /usr/lib/mailman.*/mail/wrapper,	/usr/lib/mailman.*/bin/mailmanctl,
	    /usr/lib/mailman.*/scripts/mailman,    /usr/lib/mailman.*/bin/mm-handler.*,    /usr/share/doc/mailman.*/mm-handler.*,   /usr/lib/mail-
	    man/bin/mm-handler.*, /usr/lib/mailman/bin/mailmanctl

       mailman_mail_tmp_t

       - Set files with the mailman_mail_tmp_t type, if you want to store mailman mail temporary files in the /tmp directories.

       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.
