6 tmpreaper_selinux - Security Enhanced Linux Policy for the tmpreaper
7 processes
8
10 Security-Enhanced Linux secures the tmpreaper processes via flexible
11 mandatory access control.
12
13 The tmpreaper processes execute with the tmpreaper_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep tmpreaper_t
20
21
22
24 The tmpreaper_t SELinux type can be entered via the tmpreaper_exec_t
25 file type.
26
27 The default entrypoint paths for the tmpreaper_t domain are the follow‐
28 ing:
29
30 /usr/sbin/tmpwatch, /usr/sbin/tmpreaper, /etc/rc.d/init.d/mountall-
31 bootclean.sh, /etc/rc.d/init.d/mountnfs-bootclean.sh
32
34 SELinux defines process types (domains) for each process running on the
35 system
36
37 You can see the context of a process using the -Z option to ps
38
39 Policy governs the access confined processes have to files. SELinux
40 tmpreaper policy is very flexible allowing users to setup their tm‐
41 preaper processes in as secure a method as possible.
42
43 The following process types are defined for tmpreaper:
44
45 tmpreaper_t
46
47 Note: semanage permissive -a tmpreaper_t can be used to make the
48 process type tmpreaper_t permissive. SELinux does not deny access to
49 permissive process types, but the AVC (SELinux denials) messages are
50 still generated.
51
52
54 SELinux policy is customizable based on least access required. tm‐
55 preaper policy is extremely flexible and has several booleans that al‐
56 low you to manipulate the policy and run tmpreaper with the tightest
57 access possible.
58
59
60
61 If you want to allow all domains to execute in fips_mode, you must turn
62 on the fips_mode boolean. Enabled by default.
63
64 setsebool -P fips_mode 1
65
66
67
68 If you want to allow system to run with NIS, you must turn on the
69 nis_enabled boolean. Disabled by default.
70
71 setsebool -P nis_enabled 1
72
73
74
76 The SELinux process type tmpreaper_t can manage files labeled with the
77 following file types. The paths listed are the default paths for these
78 file types. Note the processes UID still need to have DAC permissions.

131 SELinux requires files to have an extended attribute to define the file
132 type.
133
134 You can see the context of a file using the -Z option to ls
135
136 Policy governs the access confined processes have to these files.
137 SELinux tmpreaper policy is very flexible allowing users to setup their
138 tmpreaper processes in as secure a method as possible.
139
140 STANDARD FILE CONTEXT
141
142 SELinux defines the file context types for the tmpreaper, if you wanted
143 to store files with these types in a different paths, you need to exe‐
144 cute the semanage command to specify alternate labeling and then use
145 restorecon to put the labels on disk.
146
147 semanage fcontext -a -t tmpreaper_exec_t '/srv/tmpreaper/content(/.*)?'
148 restorecon -R -v /srv/mytmpreaper_content
149
150 Note: SELinux often uses regular expressions to specify labels that
151 match multiple files.
152
153 The following file types are defined for tmpreaper:
154
155
156
157 tmpreaper_exec_t
158
159 - Set files with the tmpreaper_exec_t type, if you want to transition
160 an executable to the tmpreaper_t domain.
161
162
163 Paths:
164 /usr/sbin/tmpwatch, /usr/sbin/tmpreaper, /etc/rc.d/init.d/moun‐
165 tall-bootclean.sh, /etc/rc.d/init.d/mountnfs-bootclean.sh
166
167
168 Note: File context can be temporarily modified with the chcon command.
169 If you want to permanently change the file context you need to use the
170 semanage fcontext command. This will modify the SELinux labeling data‐
171 base. You will need to use restorecon to apply the labels.
172
173
175 semanage fcontext can also be used to manipulate default file context
176 mappings.
177
178 semanage permissive can also be used to manipulate whether or not a
179 process type is permissive.
180
181 semanage module can also be used to enable/disable/install/remove pol‐
182 icy modules.
183
184 semanage boolean can also be used to manipulate the booleans
185
186
187 system-config-selinux is a GUI tool available to customize SELinux pol‐
188 icy settings.
