NAME

6       hald_selinux - Security Enhanced Linux Policy for the hald processes
7

DESCRIPTION

9       Security-Enhanced  Linux secures the hald processes via flexible manda‐
10       tory access control.
11
12       The hald processes execute with the hald_t SELinux type. You can  check
13       if  you  have  these processes running by executing the ps command with
14       the -Z qualifier.
15
16       For example:
17
18       ps -eZ | grep hald_t
19
20
21

ENTRYPOINTS

23       The hald_t SELinux type can be entered via the hald_exec_t file type.
24
25       The default entrypoint paths for the hald_t domain are the following:
26
27       /usr/sbin/hald,                           /usr/libexec/hal-hotplug-map,
28       /etc/hal/device.d/printer_remove.hal,                 /etc/hal/capabil‐
29       ity.d/printer_update.hal

PROCESS TYPES

32       SELinux defines process types (domains) for each process running on the
33       system
34
35       You can see the context of a process using the -Z option to ps
36
37       Policy  governs  the  access confined processes have to files.  SELinux
38       hald policy is very flexible allowing users to setup  their  hald  pro‐
39       cesses in as secure a method as possible.
40
41       The following process types are defined for hald:
42
43       hald_mac_t, hald_dccm_t, hald_sonypic_t, hald_acl_t, hald_t, hald_keymap_t
44
45       Note:  semanage  permissive  -a  hald_t can be used to make the process
46       type hald_t permissive. SELinux does  not  deny  access  to  permissive
47       process  types, but the AVC (SELinux denials) messages are still gener‐
48       ated.

BOOLEANS

52       SELinux policy is customizable based on least  access  required.   hald
53       policy is extremely flexible and has several booleans that allow you to
54       manipulate the policy and run hald with the tightest access possible.

FILE CONTEXTS

332       SELinux requires files to have an extended attribute to define the file
333       type.
334
335       You can see the context of a file using the -Z option to ls
336
337       Policy  governs  the  access  confined  processes  have to these files.
338       SELinux hald policy is very flexible allowing users to setup their hald
339       processes in as secure a method as possible.
340
341       EQUIVALENCE DIRECTORIES
342
343
344       hald  policy  stores  data  with  multiple different file context types
345       under the /var/log/pm directory.  If you would like to store  the  data
346       in  a different directory you can use the semanage command to create an
347       equivalence mapping.  If you wanted to store this data under  the  /srv
348       dirctory you would execute the following command:
349
350       semanage fcontext -a -e /var/log/pm /srv/pm
351       restorecon -R -v /srv/pm
352
353       hald  policy  stores  data  with  multiple different file context types
354       under the /var/run/pm directory.  If you would like to store  the  data
355       in  a different directory you can use the semanage command to create an
356       equivalence mapping.  If you wanted to store this data under  the  /srv
357       dirctory you would execute the following command:
358
359       semanage fcontext -a -e /var/run/pm /srv/pm
360       restorecon -R -v /srv/pm
361
362       hald  policy  stores  data  with  multiple different file context types
363       under the /var/run/hald directory.  If you would like to store the data
364       in  a different directory you can use the semanage command to create an
365       equivalence mapping.  If you wanted to store this data under  the  /srv
366       dirctory you would execute the following command:
367
368       semanage fcontext -a -e /var/run/hald /srv/hald
369       restorecon -R -v /srv/hald
370
371       STANDARD FILE CONTEXT
372
373       SELinux  defines  the file context types for the hald, if you wanted to
374       store files with these types in a diffent paths, you  need  to  execute
375       the  semanage  command  to  sepecify  alternate  labeling  and then use
376       restorecon to put the labels on disk.
377
378       semanage fcontext -a -t hald_var_run_t '/srv/myhald_content(/.*)?'
379       restorecon -R -v /srv/myhald_content
380
381       Note: SELinux often uses regular expressions  to  specify  labels  that
382       match multiple files.
383
384       The following file types are defined for hald:
385
386
387
388       hald_acl_exec_t
