6 qdiskd_selinux - Security Enhanced Linux Policy for the qdiskd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the qdiskd processes via flexible
11 mandatory access control.
12 The qdiskd processes execute with the qdiskd_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 qdiskd_t
20
24 The qdiskd_t SELinux type can be entered via the qdiskd_exec_t file
25 type.
26 The default entrypoint paths for the qdiskd_t domain are the following:
28 /usr/sbin/qdiskd
30
32 SELinux defines process types (domains) for each process running on the
33 system
34 You can see the context of a process using the -Z option to ps
36 Policy governs the access confined processes have to files. SELinux
38 qdiskd policy is very flexible allowing users to setup their qdiskd
39 processes in as secure a method as possible.
40 The following process types are defined for qdiskd:
42 qdiskd_t
44 Note: semanage permissive -a qdiskd_t can be used to make the process
46 type qdiskd_t permissive. SELinux does not deny access to permissive
47 process types, but the AVC (SELinux denials) messages are still gener‐
48 ated.
49
52 SELinux policy is customizable based on least access required. qdiskd
53 policy is extremely flexible and has several booleans that allow you to
54 manipulate the policy and run qdiskd with the tightest access possible.

153 you must turn on the nscd_use_shm boolean. Enabled by default.
154 setsebool -P nscd_use_shm 1
156
160 The SELinux process type qdiskd_t can manage files labeled with the
161 following file types. The paths listed are the default paths for these
162 file types. Note the processes UID still need to have DAC permissions.

237 SELinux requires files to have an extended attribute to define the file
238 type.
239 You can see the context of a file using the -Z option to ls
241 Policy governs the access confined processes have to these files.
243 SELinux qdiskd policy is very flexible allowing users to setup their
244 qdiskd processes in as secure a method as possible.
245 STANDARD FILE CONTEXT
247 SELinux defines the file context types for the qdiskd, if you wanted to
249 store files with these types in a diffent paths, you need to execute
250 the semanage command to sepecify alternate labeling and then use
251 restorecon to put the labels on disk.
252 semanage fcontext -a -t qdiskd_var_run_t '/srv/myqdiskd_content(/.*)?'
254 restorecon -R -v /srv/myqdiskd_content
255 Note: SELinux often uses regular expressions to specify labels that
257 match multiple files.
258 The following file types are defined for qdiskd:
260 qdiskd_exec_t
264 - Set files with the qdiskd_exec_t type, if you want to transition an
266 executable to the qdiskd_t domain.
267 qdiskd_tmpfs_t
271 - Set files with the qdiskd_tmpfs_t type, if you want to store qdiskd
273 files on a tmpfs file system.
274 qdiskd_var_lib_t
278 - Set files with the qdiskd_var_lib_t type, if you want to store the
280 qdiskd files under the /var/lib directory.
281 qdiskd_var_log_t
285 - Set files with the qdiskd_var_log_t type, if you want to treat the
287 data as qdiskd var log data, usually stored under the /var/log direc‐
288 tory.
289 qdiskd_var_run_t
293 - Set files with the qdiskd_var_run_t type, if you want to store the
295 qdiskd files under the /run or /var/run directory.
296 Note: File context can be temporarily modified with the chcon command.
300 If you want to permanently change the file context you need to use the
301 semanage fcontext command. This will modify the SELinux labeling data‐
302 base. You will need to use restorecon to apply the labels.
303
306 semanage fcontext can also be used to manipulate default file context
307 mappings.
308 semanage permissive can also be used to manipulate whether or not a
310 process type is permissive.
311 semanage module can also be used to enable/disable/install/remove pol‐
313 icy modules.
314 semanage boolean can also be used to manipulate the booleans
316 system-config-selinux is a GUI tool available to customize SELinux pol‐
319 icy settings.
