NAME

6       rolekit_selinux  -  Security Enhanced Linux Policy for the rolekit pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures  the  rolekit  processes  via  flexible
11       mandatory access control.
12
13       The  rolekit processes execute with the rolekit_t SELinux type. You can
14       check if you have these processes running by executing the  ps  command
15       with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep rolekit_t
20
21
22

ENTRYPOINTS

24       The  rolekit_t  SELinux type can be entered via the rolekit_exec_t file
25       type.
26
27       The default entrypoint paths for the rolekit_t domain are  the  follow‐
28       ing:
29
30       /usr/sbin/roled
31

PROCESS TYPES

33       SELinux defines process types (domains) for each process running on the
34       system
35
36       You can see the context of a process using the -Z option to ps
37
38       Policy governs the access confined processes have  to  files.   SELinux
39       rolekit  policy  is very flexible allowing users to setup their rolekit
40       processes in as secure a method as possible.
41
42       The following process types are defined for rolekit:
43
44       rolekit_t
45
46       Note: semanage permissive -a rolekit_t can be used to make the  process
47       type  rolekit_t  permissive. SELinux does not deny access to permissive
48       process types, but the AVC (SELinux denials) messages are still  gener‐
49       ated.
50
51

BOOLEANS

53       SELinux policy is customizable based on least access required.  rolekit
54       policy is extremely flexible and has several booleans that allow you to
55       manipulate  the  policy and run rolekit with the tightest access possi‐
56       ble.
57
58
59
60       If you want to deny user domains applications to map a memory region as
61       both  executable  and  writable,  this  is dangerous and the executable
62       should be reported in bugzilla, you must turn on the deny_execmem bool‐
63       ean. Enabled by default.
64
65       setsebool -P deny_execmem 1
66
67
68
69       If  you  want  to control the ability to mmap a low area of the address
70       space, as configured by /proc/sys/vm/mmap_min_addr, you  must  turn  on
71       the mmap_low_allowed boolean. Disabled by default.
72
73       setsebool -P mmap_low_allowed 1
74
75
76
77       If  you want to disable kernel module loading, you must turn on the se‐
78       cure_mode_insmod boolean. Enabled by default.
79
80       setsebool -P secure_mode_insmod 1
81
82
83
84       If you want to allow unconfined executables to make their  heap  memory
85       executable.   Doing  this  is  a  really bad idea. Probably indicates a
86       badly coded executable, but could indicate an attack.  This  executable
87       should  be  reported  in bugzilla, you must turn on the selinuxuser_ex‐
88       echeap boolean. Disabled by default.
89
90       setsebool -P selinuxuser_execheap 1
91
92
93
94       If you want to allow unconfined executables to make  their  stack  exe‐
95       cutable.   This  should  never, ever be necessary. Probably indicates a
96       badly coded executable, but could indicate an attack.  This  executable
97       should  be reported in bugzilla, you must turn on the selinuxuser_exec‐
98       stack boolean. Enabled by default.
99
100       setsebool -P selinuxuser_execstack 1

MANAGED FILES

105       The SELinux process type rolekit_t can manage files  labeled  with  the
106       following file types.  The paths listed are the default paths for these
107       file types.  Note the processes UID still need to have DAC permissions.
108
109       file_type
110
111            all files on the system
112
113

FILE CONTEXTS

115       SELinux requires files to have an extended attribute to define the file
116       type.
117
118       You can see the context of a file using the -Z option to ls
119
120       Policy  governs  the  access  confined  processes  have to these files.
121       SELinux rolekit policy is very flexible allowing users to  setup  their
122       rolekit processes in as secure a method as possible.
123
124       STANDARD FILE CONTEXT
125
126       SELinux  defines  the file context types for the rolekit, if you wanted
127       to store files with these types in a diffent paths, you need to execute
128       the  semanage  command  to  specify alternate labeling and then use re‐
129       storecon to put the labels on disk.
130
131       semanage  fcontext  -a  -t   rolekit_unit_file_t   '/srv/myrolekit_con‐
132       tent(/.*)?'
133       restorecon -R -v /srv/myrolekit_content
134
135       Note:  SELinux  often  uses  regular expressions to specify labels that
136       match multiple files.
137
138       The following file types are defined for rolekit:
139
140
141
142       rolekit_exec_t
143
144       - Set files with the rolekit_exec_t type, if you want to transition  an
145       executable to the rolekit_t domain.
146
147
148
149       rolekit_tmp_t
150
151       -  Set  files with the rolekit_tmp_t type, if you want to store rolekit
152       temporary files in the /tmp directories.
153
154
155
156       rolekit_unit_file_t
157
158       - Set files with the rolekit_unit_file_t type, if you want to treat the
159       files as rolekit unit content.
160
161
162
163       Note:  File context can be temporarily modified with the chcon command.
164       If you want to permanently change the file context you need to use  the
165       semanage fcontext command.  This will modify the SELinux labeling data‐
166       base.  You will need to use restorecon to apply the labels.
167
168

COMMANDS

170       semanage fcontext can also be used to manipulate default  file  context
171       mappings.
172
173       semanage  permissive  can  also  be used to manipulate whether or not a
174       process type is permissive.
175
176       semanage module can also be used to enable/disable/install/remove  pol‐
177       icy modules.
178
179       semanage boolean can also be used to manipulate the booleans
180
181
182       system-config-selinux is a GUI tool available to customize SELinux pol‐
183       icy settings.
