NAME

       fetchmail_selinux - Security Enhanced Linux Policy for the fetchmail processes

DESCRIPTION

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

       The  fetchmail  processes  execute with the fetchmail_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 fetchmail_t

ENTRYPOINTS

       The fetchmail_t SELinux type can be entered via the fetchmail_exec_t file type.

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

       /usr/bin/fetchmail

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 fetchmail policy is very flexible allowing users to setup their fetch-
       mail processes in as secure a method as possible.

       The following process types are defined for fetchmail:

       fetchmail_t

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

BOOLEANS

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

       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 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

MANAGED FILES

       The  SELinux  process  type fetchmail_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.

       cluster_conf_t

	    /etc/cluster(/.*)?

       cluster_var_lib_t

	    /var/lib/pcsd(/.*)?
	    /var/lib/cluster(/.*)?
	    /var/lib/openais(/.*)?
	    /var/lib/pengine(/.*)?
	    /var/lib/corosync(/.*)?
	    /usr/lib/heartbeat(/.*)?
	    /var/lib/heartbeat(/.*)?
	    /var/lib/pacemaker(/.*)?

       cluster_var_run_t

	    /var/run/crm(/.*)?
	    /var/run/cman_.*
	    /var/run/rsctmp(/.*)?
	    /var/run/aisexec.*
	    /var/run/heartbeat(/.*)?
	    /var/run/cpglockd.pid
	    /var/run/corosync.pid
	    /var/run/rgmanager.pid
	    /var/run/cluster/rgmanager.sk

       fetchmail_uidl_cache_t

	    /var/lib/fetchmail(/.*)?
	    /var/mail/.fetchmail-UIDL-cache

       fetchmail_var_run_t

	    /var/run/fetchmail.*

       root_t

	    /
	    /initrd

       sendmail_log_t

	    /var/log/mail(/.*)?
	    /var/log/sendmail.st.*

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

       STANDARD FILE CONTEXT

       SELinux	defines  the  file  context types for the fetchmail, 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 fetchmail_etc_t '/srv/fetchmail/content(/.*)?'
       restorecon -R -v /srv/myfetchmail_content

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

       The following file types are defined for fetchmail:

       fetchmail_etc_t

       - Set files with the fetchmail_etc_t type, if you want to store fetchmail files in the /etc directories.

       fetchmail_exec_t

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

       fetchmail_home_t

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

       Paths:
	    /root/.fetchmailrc, /home/[^/]*/.fetchmailrc

       fetchmail_initrc_exec_t

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

       fetchmail_log_t

       - Set files with the fetchmail_log_t type, if you want to treat the data as fetchmail log data, usually stored under  the  /var/log  direc-
       tory.

       fetchmail_uidl_cache_t

       - Set files with the fetchmail_uidl_cache_t type, if you want to store the files under the /var/cache directory.

       Paths:
	    /var/lib/fetchmail(/.*)?, /var/mail/.fetchmail-UIDL-cache

       fetchmail_var_run_t

       - Set files with the fetchmail_var_run_t type, if you want to store the fetchmail files under the /run or /var/run directory.

       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.
