dlm_controld_selinux(8) SELinux Policy dlm_controld dlm_controld_selinux(8)

NAME dlm_controld_selinux - Security Enhanced Linux Policy for the dlm_con- trold processes

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

The dlm_controld processes execute with the dlm_controld_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 dlm_controld_t

ENTRYPOINTS The dlm_controld_t SELinux type can be entered via the dlm_con- trold_exec_t file type.

The default entrypoint paths for the dlm_controld_t domain are the fol- lowing:

/usr/sbin/dlm_controld

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

The following process types are defined for dlm_controld:

dlm_controld_t

Note: semanage permissive -a dlm_controld_t can be used to make the process type dlm_controld_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. dlm_controld policy is extremely flexible and has several booleans that allow you to manipulate the policy and run dlm_controld with the tight- est access possible.

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

setsebool -P allow_daemons_dump_core 1

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

setsebool -P allow_daemons_use_tcp_wrapper 1

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

setsebool -P allow_daemons_use_tty 1

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

setsebool -P allow_domain_fd_use 1

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

setsebool -P allow_kerberos 1

If you want to allow sysadm to debug or ptrace all processes, you must turn on the allow_ptrace boolean. Disabled by default.

setsebool -P allow_ptrace 1

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

setsebool -P allow_ypbind 1

If you want to allow cluster administrative cluster domains memcheck- amd64- to use executable memory, you must turn on the clus- ter_use_execmem boolean. Disabled by default.

setsebool -P cluster_use_execmem 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 enable support for upstart as the init program, you must turn on the init_upstart boolean. Enabled by default.

setsebool -P init_upstart 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 dlm_controld_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 per- missions.

cluster_log

cluster_var_lib_t

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

configfs_t

dlm_controld_tmpfs_t

dlm_controld_var_run_t

/var/run/dlm_controld.pid

initrc_tmp_t

root_t

/ /initrd

sysfs_t

/sys(/.*)?

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

STANDARD FILE CONTEXT

SELinux defines the file context types for the dlm_controld, 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 dlm_controld_exec_t /srv/dlm_controld/con- tent(/.*)? restorecon -R -v /srv/mydlm_controld_content

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

The following file types are defined for dlm_controld:

dlm_controld_exec_t

- Set files with the dlm_controld_exec_t type, if you want to transi- tion an executable to the dlm_controld_t domain.

dlm_controld_tmpfs_t

- Set files with the dlm_controld_tmpfs_t type, if you want to store dlm controld files on a tmpfs file system.

dlm_controld_var_log_t

- Set files with the dlm_controld_var_log_t type, if you want to treat the data as dlm controld var log data, usually stored under the /var/log directory.

dlm_controld_var_run_t

- Set files with the dlm_controld_var_run_t type, if you want to store the dlm controld 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 pol- icy modules.

semanage boolean can also be used to manipulate the booleans

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