NAME
mcstransd - MCS (Multiple Category System) daemon. Translates SELinux MCS/MLS labels to human readable form. SYNOPSIS
mcstransd DESCRIPTION
This manual page describes the mcstransd program. This daemon reads /etc/selinux/{SELINUXTYPE}/setrans.conf and /etc/selinux/{SELINUXTYPE}/secolors.conf configuration files, and communi- cates with libselinux via a socket in /var/run/setrans. It also watches for files created in /var/run/setrans and uses the contents of these files to generate translations to the names. For example writing a file /var/run/setrans/mydomain with content of s0:c1,c2 will cause mcstrans to translate s0:c1,c2 to mydomain. AUTHOR

NAME
setrans_selinux - Security Enhanced Linux Policy for the setrans processes DESCRIPTION
Security-Enhanced Linux secures the setrans processes via flexible mandatory access control. The setrans processes execute with the setrans_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 setrans_t ENTRYPOINTS
The setrans_t SELinux type can be entered via the setrans_exec_t file type. The default entrypoint paths for the setrans_t domain are the following: /sbin/mcstransd, /usr/sbin/mcstransd 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 setrans policy is very flexible allowing users to setup their setrans processes in as secure a method as possible. The following process types are defined for setrans: setrans_t Note: semanage permissive -a setrans_t can be used to make the process type setrans_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. setrans policy is extremely flexible and has several booleans that allow you to manipulate the policy and run setrans 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 MANAGED FILES
The SELinux process type setrans_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 root_t / /initrd security_t /selinux setrans_var_run_t /var/run/setrans(/.*)? /var/run/mcstransd.pid 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 setrans policy is very flexible allowing users to setup their setrans processes in as secure a method as possible. STANDARD FILE CONTEXT SELinux defines the file context types for the setrans, 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 setrans_exec_t '/srv/setrans/content(/.*)?' restorecon -R -v /srv/mysetrans_content Note: SELinux often uses regular expressions to specify labels that match multiple files. The following file types are defined for setrans: setrans_exec_t - Set files with the setrans_exec_t type, if you want to transition an executable to the setrans_t domain. Paths: /sbin/mcstransd, /usr/sbin/mcstransd setrans_initrc_exec_t - Set files with the setrans_initrc_exec_t type, if you want to transition an executable to the setrans_initrc_t domain. setrans_var_run_t - Set files with the setrans_var_run_t type, if you want to store the setrans files under the /run or /var/run directory. Paths: /var/run/setrans(/.*)?, /var/run/mcstransd.pid 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.
