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.

177 The SELinux process type qdiskd_t can manage files labeled with the
178 following file types. The paths listed are the default paths for these
179 file types. Note the processes UID still need to have DAC permissions.

232 SELinux requires files to have an extended attribute to define the file
233 type.
234 You can see the context of a file using the -Z option to ls
236 Policy governs the access confined processes have to these files.
238 SELinux qdiskd policy is very flexible allowing users to setup their
239 qdiskd processes in as secure a method as possible.
240 STANDARD FILE CONTEXT
242 SELinux defines the file context types for the qdiskd, if you wanted to
244 store files with these types in a diffent paths, you need to execute
245 the semanage command to sepecify alternate labeling and then use
246 restorecon to put the labels on disk.
247 semanage fcontext -a -t qdiskd_var_run_t '/srv/myqdiskd_content(/.*)?'
249 restorecon -R -v /srv/myqdiskd_content
250 Note: SELinux often uses regular expressions to specify labels that
252 match multiple files.
253 The following file types are defined for qdiskd:
255 qdiskd_exec_t
259 - Set files with the qdiskd_exec_t type, if you want to transition an
261 executable to the qdiskd_t domain.
262 qdiskd_tmpfs_t
266 - Set files with the qdiskd_tmpfs_t type, if you want to store qdiskd
268 files on a tmpfs file system.
269 qdiskd_var_lib_t
273 - Set files with the qdiskd_var_lib_t type, if you want to store the
275 qdiskd files under the /var/lib directory.
276 qdiskd_var_log_t
280 - Set files with the qdiskd_var_log_t type, if you want to treat the
282 data as qdiskd var log data, usually stored under the /var/log direc‐
283 tory.
284 qdiskd_var_run_t
288 - Set files with the qdiskd_var_run_t type, if you want to store the
290 qdiskd files under the /run or /var/run directory.
291 Note: File context can be temporarily modified with the chcon command.
295 If you want to permanently change the file context you need to use the
296 semanage fcontext command. This will modify the SELinux labeling data‐
297 base. You will need to use restorecon to apply the labels.
298
301 semanage fcontext can also be used to manipulate default file context
302 mappings.
303 semanage permissive can also be used to manipulate whether or not a
305 process type is permissive.
306 semanage module can also be used to enable/disable/install/remove pol‐
308 icy modules.
309 semanage boolean can also be used to manipulate the booleans
311 system-config-selinux is a GUI tool available to customize SELinux pol‐
314 icy settings.
