6 initrc_selinux - Security Enhanced Linux Policy for the initrc pro‐
7 cesses
8
10 Security-Enhanced Linux secures the initrc processes via flexible
11 mandatory access control.
12 The initrc processes execute with the initrc_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16 For example:
18 ps -eZ | grep initrc_t
20
24 The initrc_t SELinux type can be entered via the amtu_initrc_exec_t,

247 SELinux defines process types (domains) for each process running on the
248 system
249 You can see the context of a process using the -Z option to ps
251 Policy governs the access confined processes have to files. SELinux
253 initrc policy is very flexible allowing users to setup their initrc
254 processes in as secure a method as possible.
255 The following process types are defined for initrc:
257 initrc_t
259 Note: semanage permissive -a initrc_t can be used to make the process
261 type initrc_t permissive. SELinux does not deny access to permissive
262 process types, but the AVC (SELinux denials) messages are still gener‐
263 ated.
264
267 SELinux policy is customizable based on least access required. initrc
268 policy is extremely flexible and has several booleans that allow you to
269 manipulate the policy and run initrc with the tightest access possible.
270 If you want to deny user domains applications to map a memory region as
274 both executable and writable, this is dangerous and the executable
275 should be reported in bugzilla, you must turn on the deny_execmem bool‐
276 ean. Enabled by default.
277 setsebool -P deny_execmem 1
279 If you want to control the ability to mmap a low area of the address
283 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
284 the mmap_low_allowed boolean. Disabled by default.
285 setsebool -P mmap_low_allowed 1
287 If you want to disable kernel module loading, you must turn on the
291 secure_mode_insmod boolean. Enabled by default.
292 setsebool -P secure_mode_insmod 1
294 If you want to allow unconfined executables to make their heap memory
298 executable. Doing this is a really bad idea. Probably indicates a
299 badly coded executable, but could indicate an attack. This executable
300 should be reported in bugzilla, you must turn on the selin‐
301 uxuser_execheap boolean. Disabled by default.
302 setsebool -P selinuxuser_execheap 1
304 If you want to allow unconfined executables to make their stack exe‐
308 cutable. This should never, ever be necessary. Probably indicates a
309 badly coded executable, but could indicate an attack. This executable
310 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
311 stack boolean. Disabled by default.
312 setsebool -P selinuxuser_execstack 1

318 The SELinux process type initrc_t can manage files labeled with the
319 following file types. The paths listed are the default paths for these
320 file types. Note the processes UID still need to have DAC permissions.
321 file_type
323 all files on the system
325
328 SELinux requires files to have an extended attribute to define the file
329 type.
330 You can see the context of a file using the -Z option to ls
332 Policy governs the access confined processes have to these files.
334 SELinux initrc policy is very flexible allowing users to setup their
335 initrc processes in as secure a method as possible.
336 STANDARD FILE CONTEXT
338 SELinux defines the file context types for the initrc, if you wanted to
340 store files with these types in a diffent paths, you need to execute
341 the semanage command to sepecify alternate labeling and then use
342 restorecon to put the labels on disk.
343 semanage fcontext -a -t initrc_var_run_t '/srv/myinitrc_content(/.*)?'
345 restorecon -R -v /srv/myinitrc_content
346 Note: SELinux often uses regular expressions to specify labels that
348 match multiple files.
349 The following file types are defined for initrc:
351 initrc_devpts_t
355 - Set files with the initrc_devpts_t type, if you want to treat the
357 files as initrc devpts data.
358 initrc_exec_t
362 - Set files with the initrc_exec_t type, if you want to transition an
364 executable to the initrc_t domain.
365 Paths:
368 /etc/init.d/.*, /etc/rc.d/rc.[^/]+, /etc/rc.d/init.d/.*,
369 /opt/nfast/sbin/init.d-ncipher, /usr/libexec/dcc/stop-.*,
370 /usr/libexec/dcc/start-.*, /usr/lib/systemd/fedora[^/]*,
371 /opt/nfast/scripts/init.d/(.*), /etc/rc.d/rc, /etc/X11/prefdm,
372 /usr/sbin/startx, /usr/bin/sepg_ctl, /usr/sbin/start-dirsrv,
373 /usr/sbin/open_init_pty, /usr/sbin/restart-dirsrv, /etc/syscon‐
374 fig/network-scripts/ifup-ipsec, /usr/share/system-config-ser‐
375 vices/system-config-services-mechanism.py
376 initrc_state_t
379 - Set files with the initrc_state_t type, if you want to treat the
381 files as initrc state data.
382 initrc_tmp_t
386 - Set files with the initrc_tmp_t type, if you want to store initrc
388 temporary files in the /tmp directories.
389 initrc_var_log_t
393 - Set files with the initrc_var_log_t type, if you want to treat the
395 data as initrc var log data, usually stored under the /var/log direc‐
396 tory.
397 initrc_var_run_t
401 - Set files with the initrc_var_run_t type, if you want to store the
403 initrc files under the /run or /var/run directory.
404 Paths:
407 /var/run/utmp, /var/run/random-seed, /var/run/runlevel.dir,
408 /var/run/setmixer_flag
409 Note: File context can be temporarily modified with the chcon command.
412 If you want to permanently change the file context you need to use the
413 semanage fcontext command. This will modify the SELinux labeling data‐
414 base. You will need to use restorecon to apply the labels.
415
418 semanage fcontext can also be used to manipulate default file context
419 mappings.
420 semanage permissive can also be used to manipulate whether or not a
422 process type is permissive.
423 semanage module can also be used to enable/disable/install/remove pol‐
425 icy modules.
426 semanage boolean can also be used to manipulate the booleans
428 system-config-selinux is a GUI tool available to customize SELinux pol‐
431 icy settings.
